We have developed a systematic design task planning method based on a design structure matrix(DSM) and a lumped model- based framework for knowledge sharing in a concurrent design environment as key techniques for developing higher quality products in a shorter design time. The DSM facilitates systematic analysis of dependencies among design tasks and optimization of the design process. The framework based on a lumped model description of mechanical systems enables concurrent and cooperative work among multidisciplinary designers at an early stage of the design process. In this paper, we also discuss the relationships between these techniques and the product development flow from product definition to detailed design. (author)

The current technologies of hydraulic pumps and motors for construction machinery and vehicles are discussed. A bent axis type axial double piston pump for negative feedback control systems and a cam plate type double piston pump superior in responsibility for load sensing control systems are usually used for hydraulic shovels. A split flow type double piston pump is on the increase for mini-shovels, having an unsolved problem as pressure fluctuation. The use of piston pumps is increasing rapidly for cranes, and a cam plate type axial piston pump is mainly used for large cranes. A traveling motor integrated with a transmission gear is usually used for hydraulic shovels, and a swing motor with valves and a brake in its casing is also used. A bent axis type variable displacement motor combined with a transmission is on the increase for winches, and a reliable preventing system from drop of suspended loading is expected to be developed rapidly.

From the viewpoint that the manufacturing process, expendable items, and recycling should all be taken into consideration when machine tool energy consumption is the matter to discuss, it is concluded that the most important policy to follow in the effort to enhance energy conservation is to enable the tool to operate without hydraulic systems. For the realization of a general-purpose machine tool (lathe) to operate free of hydraulic systems, efforts are exerted to develop element technologies, tool rests, tail stocks, and chuck drives usable for the construction of a practical hydraulic system-free machine tool. In fiscal 2000, comprehensive evaluation of experimental machine tools continued, problems to solve for practical application were put together for the fabrication of improved units, and the improved units and an improved control method were integrated into a prototype of practical machine tools. The prototype was exhibited at Japan International Machine Tool Fair (JIMTOF) as a hydraulic system-free NC (numerically controlled) lathe Type LB300, and won a high valuation. The prototype was then tested for basic performance and for possibility of improvement, and problems to be solved before commercialization were isolated. (NEDO)

The software of automotive control systems has become increasingly large and complex. High level languages (primarily C) and the compilers become more important to reduce coding time. Most compilers represent real number in the floating point format specified by IEEE standard 754. Most microprocessors in the automotive industry have no hardware for the operation using the IEEE standard due to the cost requirements, resulting in the slow execution speed and large code size. Alternative formats to increase execution speed and reduce code size are proposed. Experimental results for the alternative formats show the improvement in execution speed and code size. 4 refs., 3 figs., 2 tabs.

Effects extended to industrial areas by new energy development were analyzed by using the industrial relation table. Technological development of new energies can mass-produce energy without being restricted by energy resource availability, and retaining manufacturing facilities can exhibit energy reserve function with security. The technologies may be suitable for local energy supply. In the aspects of industrial policies and people's living, demands on diversification and improvement of the people's living may be responded, levels of scientific technologies may be enhanced, and contribution to improving the industrial structure may be expected. The energy industry includes a large number of related industries and has vast related areas. A large number of technology induced effects can be expected in the course of research and development. A market of huge size may be estimated in the future, by which level elevation of the industrial structure would be supported. Early promotion of the new energy development is an urgent assignment for the 1980's. In order to achieve this goal, it is necessary to promote research and development, proliferation and practical application, for which the physical strength of the present Japan must be utilized to its maximum in making human and fund investments. Expansion and improvement in the industrialization infrastructures are also important, whereas the government's subsidies must be increased, and vitality in the private sector must be incorporated into organized force.

This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a machine tool field. Corresponding to construction of an environment-friendly recycling economic society and economic growth as estimated change in social and industrial structure during 2010-2025, major themes are reuse of machine tools, energy saving, environment design, chip treatment and resource recovery. With preparation of information infrastructures in an advanced information society, major issues are 3D-CAD, remote diagnosis, remote control and self-restoration. Because of decline of the birth rate, positive employment of aged persons and women is desirable. New machining technology for new materials, and fusion of various machining technologies are important. For micro-technology, study should be made on the concept and effect of micro-factory (energy saving, space saving, cost reduction, higher accuracy and higher speed). For higher-accuracy machine tool, static, dynamic, thermal and movement characteristics are the key for improving the proper technology. For faster machining. fine basic structural element, faster main spindle and faster feed are important. (NEDO)

A method for determining part re-use and recycling strategy in product design is considered for optimal design of total product life cycle based on the concept of Right Quality Products. For this purpose, it is important to be able to estimate part deterioration status under various product usage conditions. For supporting product designers' decision making about the product life cycle in preliminary design phase, the deterioration estimation is not required to be very exact, but to generate every possible deterioration modes qualitatively. Then, based on these deterioration modes, functional behaviour of target products is simulated, and possible product failure modes can be generated. By utilizing the FMEA (Failure Mode and Effect Analysis) method, the effects of failure modes are evaluated, and the results are fed back to product designers for confirming their design in terms of total product life cycle optimization. A basic methodology is considered, and case study has been done for a mechanical assembly of a one-time use camera. The assembly consists of injection molded parts. Various CAE methods have been used for predicting possible part failures due to initial residual stress, warp, fatigue, creep, and wear. Then kinematic and dynamic analysis of mechanical assembly has been done for detecting the effect of part deterioration on mechanism movements. Several critical failure modes have been detected, and the effects of those failures have been checked by the FMEA method. (NEDO)

The paper described a study made during 1995 through 1998 on the application of 3D woven C/C composite materials to machine parts. The materials are large in rigidity, small in specific gravity, excellent in specific rigidity, and suitable for high speed rotation. They are excellent in heat resistance/dynamic reformation and expected as materials which can exceed limits of the existing steel for machine parts. However, to use them as machine parts, a possibility of high precision cutting is required. Therefore, a study was made on metal multi-layer membrane coating to C/C composites. Pitch-system high-elastic carbon fibers were made a 4-directional material by orienting horizontally in 3 directions at 120 degrees per plane and also orienting vertically. Various materials such as W, Mo and WC were coated by the laser assisted plasma hybrid spraying method. High adhesion coats with little pore were obtained. Multi-directionally woven C/C composites used to be poor in surface precision workability, but the problem was able to be solved by coating surfaces with metal layers and metal multi-layer membranes. The application is expanded not only to polygonal mirrors (for laser printing machine) and milling spindles, but largely to machine parts. 11 figs., 1 tab.

Technologies that have to be developed before earthquake involve active vibration control, constant surveillance, management and maintenance of disaster preventing devices, preparation and updating of disaster-related databases, etc. Technologies need to be developed for real-time disaster control in case of earthquake, which involve instant-start vibration control devices, information gathering, airborne monitoring robots, rescue robots, etc. Also required are technologies for prompt assistance and recovery after earthquake, such as those for the physical soundness related diagnosis and assessment of structures, facilities, and machinery, and for their restoration, remedy, and reinforcement. What is required is the establishment of a comprehensive technology into which all the necessary element technologies are incorporated. Since coordination is necessary with other official projects being implemented in a unified way for an industrial area, this project will be effectively accomplished when it is also treated as an official project.

A survey is conducted about highly automated machines such as industrial robots. The task to be subjected to development as derived from a survey conducted about needs is the construction of a dangerous work robot. It is pointed out that work in coal mines, tall buildings, industrial complexes, or nuclear power plants may encounter large-scale accidents, and the task is how to perform such work in an automated way. The tasks concluded to be subjected to development after a seed survey analysis are categorized into three groups of element technologies, namely, sensors and recognition function, mechanism and materials, and control and data processing. These element technologies are to be ultimately integrated into a robot, for critical work which is a combination of a highly intelligent robot main body and an integrated management system. Since it will happen that humans have to directly operate such a robot under delicate conditions and share the burden of judgement and thinking, it is also necessary to develop technologies to solve problems of man-to-robot engineering. It is proposed that a dangerous work robot research and development program be established before development is started. (NEDO)

Introduction of a number of robots and consumption of a large amount of energy are unavoidable if a complicated process operation is to be carried out by robots in an extensive work site. Great energy conservation is contrived by developing robots applicable to manufacturing in performing a variety of operations in place of human beings and thereby reducing the number of robots to work. This paper explains the fiscal 2000 results. For dual-handed cooperative tasks, a function was examined capable of gripping an object without giving a humanoid robot an instruction of an exact gripping position. A method was designed to prepare a command for the other arm through a command for one arm, with torque impedance control employed for the purpose of avoiding damage due to collision. A study was conducted on a three-dimensional shape detecting model using a visual device of a robot. In grasping problems of balance control of a humanoid robot, the behavior of a robot consisting of multi-links was considered as behavior of inverted pendulum, with possibility checked for the stabilization of the balance. For the purpose of putting the virtual robot platform previously developed to practical use, a three-dimensional operation tool of run-time user interface was developed, with research conducted on the sophistication of robot application.

A highly safe and reliable robot is being developed capable of cooperating with human beings and executing complicated operations in a human working/living space. This paper describes the fiscal 2000 results. Development of robot motion library was continued for extended task for providing services to people in care houses for the aged controlling motions of the humanoid robot. A basic design for a personal service system by the humanoid robot was conducted with the aim of nursing assistance and for the objective of developing a portable terminal type tele-operation device. A public and a home cockpit were researched with the purpose of developing user interfaces for telexistence control. A dynamic simulator for humanoid robots was built, with motions of standing-up and walking examined, in order to develop basic theories for the dual-handed tasks aided by the leg-arm cooperative motion. To develop a robot that properly and safely cooperates and coexists with the human beings, it is essential to obtain a dynamically reasonable and natural control law, so that the basic studies were conducted in this direction. With the purpose of developing a motion capture and learning system, a virtual robot platform and an information acquiring interface were developed. Studies were also conducted on modeling technique for achieving realistic material properties from high-precision image synthesis and actual images. (NEDO)

A large quantity of coolant is used in the grinding process for ensuring high accuracy and quality in the work. This presents a serious problem from the viewpoint of environmental impact or energy conservation, and now environment-conscious grinding methods requiring no or less coolant are sought for. With a view to answering the demand, efforts are exerted to put to practical use, and improve, an EcoloG grinding technique. The goal is to reduce to half the energy that the grinding process is now consuming. The EcoloG technique is a grinding method under which vegetable oil mist is cooled for lubrication and a small amount of cooling water is fed to the point of grinding for removing chips. In fiscal 1999, a survey was conducted on technical literature, patents, and the like in and out of Japan for the study of the actual state of dry machining, and then the course of future studies was clearly established. Studies were also carried out aiming at the practical application and improvement of the EcoloG grinding technique, and the technique achieved a quality level as high as that of the conventional coolant-aided method in a process of grinding a shaft to have an accurate outer diameter by use of an ordinary wheel head.

R and D on harmonized molecular materials aim at establishment of the technology fabricating self-assembled organic molecular films on solid surfaces which have potentials of mechanical response to electric fields, electroluminescence or optical functions. Molecule harmonization expresses new structures and functions difficult to be expressed by each molecule alone, by cooperative interaction between molecules due to noncovalent bond. Functional thin films were developed by controlling alignment and/or arrangement of molecules with an aid of self-assembling processes. Thiol compounds with larger dielectric anisotropy were synthesized as electric field responsive self-assembled films. {pi}-conjugated compounds composed of phenyl-capped oligothiophenes were synthesized as electroluminescent self-assembled films, and their high crystallinity and efficient electroluminescence were found. Heat- and solvent-resistant lyotropic liquid crystalline (LLC) aligning polymers such as polyamine and polyimine were synthesized as new optically functional LLC dye self-assembled films. (NEDO)

A polygonal mirror in a printer and the main shaft of a high-speed milling machine are used as models for the development of technology for applying C/C (carbon/carbon) composite materials to machine components that are required to turn at high speeds. Various C/C composites are tested for flexural strength and thermal expansion for the designing and manufacturing of C/C composites for the polygonal mirror and main shaft. The first coating on the C/C composite is deposited by laser/plasma hybrid spraying, and is a Mo coating. A spraying robot is experimentally built for homogeneous coating. In the case of polygonal mirror, an Al coating is deposited further by the gas-deposition method. The polygonal mirror proves excellent in both dimension and reflectance, and attains the target speed of 45,000rpm. In the case of milling machine main shaft, however, it is not strong enough to withstand 40,000rpm although it is a success from a viewpoint of coating technology and manufacturing technology. 15 refs., 33 figs., 13 tabs.

This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a semiconductor equipment field, viewing until 5-10 years after. For the future semiconductor industry, the favorable cycling of creation of new demands through performance improvement, and further technology innovation through market expansion is essential absolutely. Since technology development is followed by investment, not only the performance of each equipment but also the higher productivity and cost balance of the whole factory are essential. Self-intelligent function and networking are thus necessary for the equipment. As measures for environment preservation and energy saving, such innovative technologies are required as recycling, reuse, reaction process improvement and alternative technology. Because of diverse final products and a short life time of products, a large-scale collective investment is becoming difficult. A mini-line sequential investment production system according to demand scales is under investigation. Some issues such as micro-technology, realization of 300mm wafer, modularization, CIM, reliability and standardization are also described. (NEDO)

With the aim of contributing to the development of optical elements, devices, sensors, high performance catalysts, etc., R and D was conducted on fundamental technologies for creating materials using harmonized molecular actions, and the fiscal 1999 results were reported. In the R and D of self-assembled molecular film materials, an electric-field sensitive self-assembled molecular film was experimentally manufactured, as were self-assembling electroluminescent and lyotropic liquid crystal pigmentary film materials. In the R and D of mesophase materials, for rod-like liquid crystal systems, a material was successfully developed possessing a transparency of 90% in the visible region accompanied with an optical phase difference of 4.0 microns. For disk-like liquid crystal systems, a diminishing tendency of obtainable photoelectric current was confirmed even with a small change in the orientation after photopolymerization. In the R and D of microporous materials, synthesis was performed for system-controlled metallosilicates and shape-controlled microporous materials. Further, structural correlation was examined for organic templates and microporous materials. (NEDO)

Evaluation of function-enriched edible oils: Preventive effect of lipid peroxidation; (a Heat exposure: Commercial rape-seed oil and extra virgin oil were used as controls. For preparation of the test samples (function fortified oils of tomato-juice waste-residue and grape wine- ferment waste-residues, it is described in above section (1. All oil preparations were exposed to high temperature at 150oC and peroxide value (POV, acid value and TBARS were measured at various times as described. The methods of measurements of POV, acid value and TBARS were adapted conventional standard method described elsewhere. (b Light exposure: Similar to (a they were exposed to excessive light using Nippon Ikaga Kikai (Tokyo, LH-200-RDS equipped with fluorescent light tube (x3, NEC FL40S-2XN, 3.2K lux at 390-730nm. Result and Discussions: (1 Extraction of carotenoids etc. Modern edible oil refining processes are highly elaborated and efficient. The most of the commercial edible oils in the market are so purified that many important antioxidant components are mostly removed during refining process. Oils became mostly colorless and odorless; and they lack are devoid of anti-oxidative or radical scavenging components. We measured anti-alkyl peroxy radical (ROO.-scavenging activity, and found that many commercial oils have very little such activity (Figure 1. Many disposal- of tomato juice or extraction waste-residues in wine making, yet contained significant amount of functionally useful components that may be recovered by immersing the dried waste residues in the functionally poor oil, ie., low grade oils. Figure 2A, B shows it was indeed possible to recover such component like lycopene and carotenoids, and the spectrum of this oil exhibits multiple peaks correspond tomato lycopene. (2 Antioxidation activity: (a Acid value after light and heat exposure. Commercial highly purified edible oils are vulnerable for oxidation and resulting in lipid or alkyl hydroperoxides formation (ROOH, which

The R and D were carried out on a system by which the long life of coolant of machine tools can be achieved and a system to process waste efficiently, economically and with less environmental loads, and the FY 2000 results were summed up. In the R and D of a system to prevent degradation of low energy coolant, measurement was made of effects of the degradation prevention system at a laboratory level, and it was found out that propagation of bacteria causing the degradation can be prevented with pH kept high. Further, it was admitted that the alkali effect on metal formability was not very much. As to the coolant processing, in the present situation, most of the coolant is taken back by industrial waste processing dealers. So, the development of the low energy waste liquid processing system is earnestly desired. In the R and D of the low energy waste liquid processing system, test on characteristics evaluation was conducted about each method of systems. Subjects to be improved/solved were extracted such as the point that volatile organic matters are included in condensed water after evaporation of waste liquid and there seems to be a possibility of needing the secondary processing.

A lathe, which is a central tool in a factory of automobiles or home electric appliances, tends to suffer decreased machining precision resulting from thermal deformation. This project is aimed at development of the energy-saving, high-precision lathe technologies using self compulsory cooling and thermal insensitive technologies as the countermeasures against the thermal deformation. The self compulsory cooling is a method of cooling by evaporation of water with an evaporative, water-absorptive cloth being bonded to a machine tool surface around the major axis. The thermal insensitive technologies include the three-dimensionally zero-center design technologies which help design a lathe in such a way to set the processing point (tool working point) at the base of thermal deformation in the X, Y and Z axis directions; material combination technologies to control thermal deformation; and coloring technologies to control thermal deformation. The development target is the high-precision lathe fabrication technologies, which realize a temporal precision change of 1 to 2 {mu}m or less per work dimension of 100mm. The activities cover 5 areas, including development of elementary technologies for each item and construction/evaluation of the full-size test unit. (NEDO)
