Patent number: 10252386Abstract: A tool feeding mechanism for a tool driving device includes a cylinder mechanism, a positioning mechanism, and a holding mechanism. The cylinder mechanism moves a tool rotation driving device to hold and rotate a tool, in a tool axis direction on an exterior of a cylinder tube using power of a piston. The positioning mechanism is connected to the cylinder tube side of the cylinder mechanism either directly or indirectly in order to position the cylinder mechanism relative to a workpiece. The holding mechanism holds the tool rotation driving device such that the power of the piston in the cylinder mechanism is transmitted to the tool rotation driving device.Type: GrantFiled: August 20, 2013Date of Patent: April 9, 2019Assignee: SUBARU CORPORATIONInventors: Manabu Saito, Tatsuo Nakahata, Hideharu Takahashi, Toshio Nishino, Masao Watanabe

Publication number: 20070061496Abstract: The invention provides an electronic apparatus provided with electronic devices for carrying out data transmission/reception through serial communication, designed to maintain highly efficient data transmission and prevent communication errors. An RDY line 15 which is kept to a high level in a basic condition is provided and when this line is driven low by a transmitting side IC 11, a transmission request is transmitted to a receiving side IC 12 and upon receiving this request, the receiving side IC 12 drives the RDY line 15 to a low level until the own preparations for receiving data are completed, while the transmitting side IC 11 performs no data transmission until the RDY line 15 is driven high after the transmission of the transmission request, and in this way the transmitting side IC 11 and receiving side IC 12 perform a handshake.Type: ApplicationFiled: July 20, 2006Publication date: March 15, 2007Applicant: ORION ELECTRIC CO., LTD.Inventor: Toshio Nishino

Publication number: 20070002709Abstract: A disk replaying apparatus operates such that the polarity of an FA control signal is serially extracted, and a cycle T is extracted from the polarity. When a reciprocal (1/T) of the cycle T is within a “desired-rotational-speed×0.8<1/T<desired-rotational-speed×1.2” range, the reciprocal (1/T) of the cycle T is set to the rotational speed, or otherwise a cycle T is selected again. This operation is attributed to the fact a disk fixed in place is not completely parallel to the absolute position of an objective lens, such that an FE signal corresponding to the rotation of the disk can be extracted, and an FA control signal responsive thereto can be obtained. Thereby, the disk replaying apparatus exhibits high responsivity over the rotational speed control, and is realizable at low costs.Type: ApplicationFiled: June 19, 2006Publication date: January 4, 2007Applicant: ORION ELECTRIC CO., LTD.Inventor: Toshio Nishino

Patent number: 7020416Abstract: The process frame body has the guide portion, and the development device has the to-be-guided shaft. When the process frame body is unattached to the apparatus main body, the guide portion of the development device is absent, thus preventing proper attachment and positioning of the development device. The convex engagement portion is formed integrally with the development device so as to jut into the attachment path for the process frame body. This prevents attachment of the process frame body when the development device is attached first. If users try to attach the process frame body after attachment of the development device, the convex engagement portion interferes with the process frame body, thus preventing attachment of the process frame body.Type: GrantFiled: September 25, 2003Date of Patent: March 28, 2006Assignee: Sharp Kabushiki KaishaInventors: Keiji Kato, Toshio Nishino, Yasuyuki Ishiguro, Fumito Mizoguchi, Wataru Yoshida, Atsushi Inoue, Toshihide Ohgoshi

Patent number: 6868239Abstract: A detection mechanism is provided with a sealing member made of elastic material for preventing toner leakage between (a) a pierced wall surface of a toner tank through which a rotating shaft is inserted and (b) a second side plate provided on the rotating shaft. With this structure, a flat splicing surface of the sealing member is made to closely contact a second side plate that can be coated with a high lubricant member whose frictional forces is small. When a sealing force of the sealing member is strongly compressed, the sealing member prevents toner from coming into the sliding surface.Type: GrantFiled: May 6, 2003Date of Patent: March 15, 2005Assignee: Sharp Kabushiki KaishaInventors: Atsushi Inoue, Toshio Nishino, Wataru Yoshida, Fumito Mizoguchi, Keiji Katoh, Toshihide Ohgoshi

Patent number: 6853821Abstract: A toner cartridge stored in a developer casing includes a biasing force generating device, an actuating rod that switches the biasing device between an active state and a non-active state by one movement of a release member. A developer casing swings by the movement of the actuating rod and presses a developing roller with appropriate pressure to a photosensitive drum. There is a lock member that is restrained from moving by the movement of the actuating rod. The structure recited is capable of inserting and fixing the developer casing to an image forming device. Also, by one restore movement of the release member, the photosensitive drum and the developing roller are separated and the lock is released, thereby enabling removal/exchange of the developer casing.Type: GrantFiled: May 7, 2003Date of Patent: February 8, 2005Assignee: Sharp Kabushiki KaishaInventors: Yasuyuki Ishiguro, Keiji Kato, Toshio Nishino, Atsushi Inoue, Toshihide Ohgoshi, Humito Mizoguchi, Wataru Yoshida

Patent number: 6792217Abstract: A use status detecting mechanism includes a cover having an edge portion, in a portion of which a notch is formed, a moving member having a rod member, a spring portion, protrusions and grooves, and a shaft having a driving gear and ribs. In the unused state of a developing unit, the rod member is maintained to be exposed by the contact of the protrusions with the edge portion from the outside. When the developing unit is started to be used and rotation is transmitted to the driving gear, the moving member is rotated by the engagement of the ribs and the grooves, and the moving member is moved to the shaft side by the elastic force of the spring portion when the protrusions are opposed to the notches. Thus, the rod member is retreated from the exposed position.Type: GrantFiled: March 14, 2003Date of Patent: September 14, 2004Assignee: Sharp Kabushiki KaishaInventors: Toshio Nishino, Yasuyuki Ishiguro, Takeshi Wakabayashi, Toshihide Ohgoshi

Patent number: 6741822Abstract: Elastic members are fixed at one end to the housing of an image forming apparatus while their distal ends extend into the framework of the developing unit. When a toner cartridge is fitted to the framework of a developing unit, the distal ends of the elastic members abut the top surface of the toner cartridge, so that the elastic members are compressed to produce repulsive force, which in turn causes the developing unit to rotate clockwise about a support so as to bring the developer roller into pressing contact with a photoconductor.Type: GrantFiled: April 15, 2002Date of Patent: May 25, 2004Assignee: Sharp Kabushiki KaishaInventors: Yasuyuki Ishiguro, Wataru Yoshida, Toshihide Ohgoshi, Toshio Nishino, Atsushi Inoue, Takahiko Kimura

Publication number: 20030228160Abstract: In the present detection mechanism, a sealing member made of elastic material for preventing toner leakage is provided between (a) a pierced wall surface of a toner tank through which a second rotating shaft is inserted and (b) a second side plate provided on the second rotating shaft. In this manner, a flat sliding surface of the sealing member is made to closely contact the second side plate, so that it is possible to easily coat the sliding surface with a high lubricant member whose frictional forces is small. Thus, even when a sealing force of the sealing member is enhanced by strongly compressing the sealing member by means of the pierced wall surface and the second side plate so as to prevent the toner from coming into the sliding surface, it is possible to easily suppress unwanted resistance to rotation of the second rotating shaft.Type: ApplicationFiled: May 6, 2003Publication date: December 11, 2003Inventors: Atsushi Inoue, Toshio Nishino, Wataru Yoshida, Fumito Mizoguchi, Keiji Katoh, Toshihide Ohgoshi
