traffic situations in a test course (riding condition) and while watching a traffic environmental video (non-riding condition). 9632604 Research on Combination of Combined Brake System and Antilock Brake System for Motorcycles Keishin Tanaka, Takushi Matsuto, Masaie Kato, Tatsuo Hayashi, Hiroshi Ishihara (Honda R & D Co., Ltd.) Basic requirements for a motorcycle brake system include achieving adequate deceleration and improving motorcycle stability during braking with easy operation. To help realize these requirements, Combined Brake System (CBS) and Antilock Brake System (ABS) for motorcycle were researched and developed. A new brake system which combines CBS with ABS was designed and installed on a test motorcycle. The results of braking tests showed high performance in deceleration and good braking feeling especially during ABS actuation.
The Phenolic Molding Compound for Flashless Injection Molding Hidemi Yazawa, Masaei Yamada (Sumitomo Bakelite Co.,

Ltd.) Phenolic molding compound is one of the thermoset engineering plastics which have a superior heat-resistance property. As a part of studies for obtaining similar processability to thermoplastic engineering plastics in phenolic molding compound, we studied a molding compound for flashless injection molding. We found the possibility of flashless injection molding by means of decreasing the injection pressure particularly at completion of the filling by improvement of rheorogical property. 9632622 Development of Auto-Deposition Painting Toshiya Kojima, Hideo Yano (Aisin Seiki Co., Ltd.), Motoo Nakano, Hitoshi Ishii (Nihon Parkerizing Co., Ltd.) As long-lasting rust resistance is required for auto parts, we developed non-electrolytic painting (auto-deposition painting) which gives a similar level of corrosion resistance to that of cation electrodeposition and helps reduce cost and save space. In addition, paint scrap, which is a disadvantage of non-electrolytic painting, was abolished by developing chelate type recycling technology. 9632631 Development of Inner Resin Hose for Fuel Masashi Sakakibara, Isamu Terasawa (Mitsubishi Motors Corporation), Hihumi Yasumatsu, Yasumichi Ogawa, Tadashi Kasamoto, Hiroshi Nobuhara (Marugo Rubber Industries, Ltd.) In the past, vapor hoses for Strict Evaporative Emission Regulation in U.S. have been made from fluoro elastomer (FKM, Terpolymer). But these are expensive and do not have a good barrier property to alcohol blended gasoline. We have developed a new hose which is layered with a special fluoroplastic and rubbers. This hose has better barrier properties to gasoline and blended gasoline than existing FKM rubber hose and achieves a certain cost reduction. This hose can be applied not only to vapor hoses but also to other fuel hoses, such as filler hoses. Thus it has a wide range of possibilities.
Development of Bumper Recycling Technology Applying Sandwich Injection Molding Atsushi Takeuchi, Minoru Makuta, Hitoshi 9632640
Ohgane, Kenji Hamabe, Osamu Aoki (Honda R&D Co., Ltd., Tochigi R&D Center) From the viewpoint of waste treatment and natural resources conservation, there is a strong demand for the study of the technology whereby automotive coated bumpers collected from the market can be recycled into brand-new bumpers. This study reports recycle technology for recovered bumpers using "Sandwich Injection Molding Method", eliminating the separation process of coated film from the substrate. 9632659 Development of a High Performance Plastic Material for Material Consolidation - Part 1: Development of a Consolidation Material for Automotive Interior Plastic Parts Nobuya Kawamura,
Takao Nomura, Takeyoshi Nishio, Hisayuki lwai (Toyota Motor Corporation Material Engineering Div.lI) A new automotive interior component material, TSOP-5 has been developed by refining the technology utilized to develop TSOP-I, the high modulus and high flow material for bumper covers. This new interior component material has excellent molding capability (MI = 30 dg/min.), yet still maintains high impact resistance which enables the material to be used in areas such as the dash board as well as trim covers required to meet the FMVSS 214, the new side impact regulation or the FMVSS 201, the new soft upper trim regulation. 9632668 A Method for Improving Lnadability of Aluminum Bearing - Alloy Deformation and Bonding Layer Thickness - Kazuo Mastuo, Koue Ookawa (NDC Co., Ltd) Loadability of Aluminum Bearing is studied from the stand point of alloy deformation and bonding layer thickness. Slide deformation of aluminum alloys under repeated loaded conditions are evaluated and the relation between loadability and alloy property bonding layer thickness is observed. 9632677 Tribological Characterisitics of Orientated Iron Electrodeposit Films for Application to Automobile Application Tatsuya Suzuki, Takahiro Gunji, Hiroshi Koinuma, Masamune Tabata (Honda R&D Co.,
Ltd.) Iron electrodeposit films of hexagonal-like-pyramid surface morphology, which have a high orientated (222) plane were obtained by means of electrolytic bath of ferrous sulfate and pulse current method. As a result, the films had uniform and fine roughness, exceeded oil wemess characteristic, and made increased resistance of oil flow on sliding surface. We also confirmed that the films gave decrease of coefficient of kinetic friction and improvement of anti-seizure property as compared with conventional iron electrodeposit films. Application of this surface material to piston skirt surface achieved reduction of friction loss. 9632686 Development of High Strength Connecting Rod by Forging Toyohisa Manabe, Motohide Moil, Masaaki Yano, Takashi Kobayashi (Toyota Motor Corporation), Naoki Iwama, Ichie Nomura (Aichi Steel Works Co. Ltd.) We examined the material and the forging process of connecting rods for the automobile engine in order to improve the fatigue strength and to reduce weight. We developed a higher fatigue strength of material than that of conventional type, and established a lower cost method of manufacturing to control a variety of forging conditions. The fatigue strength and the buckling strength increased without hardening, and it was easy to finish by machining. Moreover little decaburization occurred in this steel. We fitted a new automobile model engine with the new connecting rods. 9632695 Life Prediction of Thermal Fatigue for Cylinder Head Masashi Uchikura, Toshiharu Matsui (Mitsubishi Motors Corporation) The thermal loads on a cylinder head are aggravated by such requirements as lighter weight and greater power output for diesel engines. In this study, the life prediction method of thermal fatigue on cylinder head caused by the thermal load was examined, and it was found that the prediction for the thermal fatigue life based on both CAE analysis and thermal fatigue data of test pieces on each material was successfully correlated with that of an actual engine.
