Patent number: 10453640Abstract: A fuse unit includes a fuse element which includes a fusible portion, a housing which accommodates the fuse element in a state that the fusible portion is exposed to an outside thereof, and a cover which is attached to the housing so as to cover the fusible portion. The cover includes a pair of side wall portions which is disposed so as to face each other with the fusible portion interposed therebetween, and a connection portion which connects the pair of side wall portions. The housing includes a guide wall which is configured to guide the cover toward the fusible portion when the cover is attached to the housing. The guide wall is inclined to a direction intersecting a separation direction in which the cover is separated from the housing.Type: GrantFiled: August 7, 2017Date of Patent: October 22, 2019Assignee: Yazaki CorporationInventors: Norihiro Ohashi, Masayoshi Ozawa

Patent number: 10211438Abstract: An electronic component protecting cover includes a fixed cover portion, a hinge portion, and a rotatable cover portion. One of the fixed cover portion and the rotatable cover portion has engaging portions at two locations, and the other of the fixed cover portion and the rotatable cover portion has catching portions at two locations, the engaging portions and the catching portions being configured to be engaged with each other. Each of the engaging portions has a pair of locking tabs, and each of the catching portions has a pair of locking frames. Because each of the engaging portions and each of the catching portions has double-locking structure, sufficient locking force can be provided.Type: GrantFiled: June 29, 2015Date of Patent: February 19, 2019Assignee: YAZAKI CORPORATIONInventors: Norihiro Ohashi, Masayoshi Ozawa

Patent number: 10056720Abstract: A fuse unit includes a bus bar and a housing. The bus bar includes a power source-side connection section, an output-side connection section, and a fusible body. A terminal configured to be connected to the output-side connection section includes a bent section and protrusion sections. The housing includes a terminal accommodation section for accommodating the output-side connection. The accommodation space is enclosed with side walls standing upright on both sides of the output-side connection section in an insertion direction of the terminal and on a deep side thereof in the insertion direction of the terminal. The terminal accommodation section includes terminal insertion start-side movement restricting walls and a height-direction and terminal insertion start-side movement restricting wall.Type: GrantFiled: December 6, 2017Date of Patent: August 21, 2018Assignee: Yazaki CorporationInventors: Norihiro Ohashi, Masayoshi Ozawa

Publication number: 20170267194Abstract: A power delivery apparatus (100) for a vehicle includes an upstream delivering portion (10) and a downstream delivering portion (20). The upstream delivering portion (10) includes: an internal input terminal (11); an external input terminal (12); and a connecting terminal (13). The internal input terminal (11), the external input terminal (12) and the connecting terminal (13) are different terminals from one another. The downstream delivering portion (20) includes: a connected terminal (23); a fuse portion (22a-22e) connected to the connected terminal (23); and a downstream output terminal (21a-21e) outputting the electric power via the fuse portion (22a-22e). The upstream delivering portion (10) and the downstream delivering portion (20) are independent members each other and are assembled to be integrated with each other to allow connecting the connecting terminal (13) and the connected terminal (23).Type: ApplicationFiled: March 9, 2017Publication date: September 21, 2017Inventors: Yoshitake Aruga, Shinichi Akiyama, Sojiro Sato, Takumi Komaba, Norihiro Ohashi, Masayoshi Ozawa

Patent number: 5473960Abstract: A steering rack shaft having a shaft body and rack teeth formed in a predetermined axial region of the shaft body. This steering rack shaft is formed such that a workpiece is quenched, and is then heated for a predetermined time at a temperature exceeding 400.degree. C. so as to be thermally refined, and the rack teeth are subsequently formed. After the formation of the rack teeth, high-frequency induction hardening is provided to form a teeth-hardened layer. Hence, the machining of the rack teeth is facilitated while reducing strain, and the rigidity and toughness of the overall steering rack shaft are improved.Type: GrantFiled: March 10, 1994Date of Patent: December 12, 1995Assignee: Kabushiki Kaisha Yamada SeisakushoInventors: Hideji Sakamoto, Masayoshi Ozawa, Seiji Kanuki, Kenji Hoshino, Toshiaki Tanaka
