Patent number: 11143060Abstract: A rocker arm includes a pair of sidewalls disposed along a heightwise direction so as to be opposed to each other. The sidewalls define a space to house a roller and have opposed portions extending in the heightwise direction relative to adjacent portions which are adjacent to the opposed portions. The opposed portions have thinner portions having smaller thicknesses than the adjacent portions.Type: GrantFiled: March 8, 2017Date of Patent: October 12, 2021Assignee: OTICS CORPORATIONInventors: Naoyuki Yamane, Kiyoshi Masegi, Kimihiko Todo

Patent number: 10508688Abstract: A bearing device includes a support having a bearing hole, a shaft member slidably inserted into the bearing hole thereby to be rotatably supported by the support, the shaft member having an axial end surface and a locking part located on the axial end surface of the shaft member to protrude in an axial direction of the shaft member from an outer periphery of the axial end surface of the shaft member. The locking part is deformed by force applied to its axial protruding end so as to bulge outward in a radial direction intersecting the axial direction, so that the bulging part is capable of being locked to a peripheral part of the bearing hole on an outer surface of the support.Type: GrantFiled: October 21, 2015Date of Patent: December 17, 2019Assignee: OTICS CORPORATIONInventors: Hideki Oka, Eiichi Nozaki, Haruyasu Tanaka, Naoyuki Yamane

Patent number: 5436431Abstract: A toner image fixing device comprises a heat roller and a lamp heater. The lamp heater is formed from a nicrome wire stretched between clamp terminals, a silica tube and ceramic holders closely fitted to respective ends of the silica tube and which have an external diameter which is substantially the same as the diameter of the heating roller. The lamp heater is secured by a lamp holder and frame to the shaft of the heat roller. The heat roller is rotatably supported by a bearing and is driven by a driving gear.Type: GrantFiled: January 7, 1994Date of Patent: July 25, 1995Assignee: Sharp Kabushiki KaishaInventors: Masaru Tsuji, Hiroshige Araki, Hideki Gotoh, Yoshikazu Kondoh, Atsuyuki Kato, Yoshinobu Tateishi, Yuhi Akagawa, Mitsuyoshi Terada, Takashi Sugito, Toshihide Ohgoshi, Naoyuki Yamane

Patent number: 5239805Abstract: The object of the present invention is to provide a method of packaging a developer cartridge especially for use in the image-forming of the electrophotographic process, the method by which the operativity of users can be improved and the pollution due to the sealing member of the developer cartridge can be prevented. The object of the present invention is achieved by fixing a free end of the above sealing member held between the sealing portions of the packing bag when the packing bag is hermetically sealed. With this, the sealing member is pulled off in accordance with the developer cartridge being drawn out from the bag when it is used. When the whole part of the developer cartridge is drawn out, the sealing member is completely pulled off, and is left inside the packing bag.Type: GrantFiled: August 26, 1992Date of Patent: August 31, 1993Assignee: Sharp Kabushiki KaishaInventors: Katsuzo Uchida, Keiji Kato, Yukinori Andou, Naoyuki Yamane, Yasuo Imai

Patent number: 5235130Abstract: A developer cartridge is provided to prevent toner from overflowing a toner hopper into a development tank, and to prevent a toner supply roller from being deformed by heavy pressure. In order to achieve the object, the developer cartridge is provided with a seal member (8) in the toner hopper (2). The seal member has one end blocking a toner supply port (9) and the other end secured to a rotary shaft (7a) of an agitating member (7). The seal member is rolled up by rotating the agitating member when using the cartridge for the first time.Type: GrantFiled: September 18, 1992Date of Patent: August 10, 1993Assignee: Sharp Kabushiki KaishaInventors: Miki Demoto, Katsuzo Uchida, Keiji Kato, Naoyuki Yamane, Yasuo Imai, Hisashi Kunihiro
