Patent number: 11953314Abstract: A bump inspection device images a wafer that includes a plurality of bumps arranged in parallel to each other. Each of the bumps is elongated along a first direction that is along a substrate surface. The bump inspection device includes: a laser-light source that emits laser light in a direction that is inclined relative to the substrate surface; a camera that images the substrate surface onto which the laser light is emitted; and a direction adjusting portion that adjusts an arrangement relation between the direction in which the laser light is emitted and an orientation of the wafer to allow the first direction to become inclined relative to the direction in which the laser light is emitted, in a plan view. The camera images the wafer while the first direction is inclined relative to the direction in which the laser light is emitted, in a plan view.Type: GrantFiled: January 11, 2023Date of Patent: April 9, 2024Assignee: NIDEC READ CORPORATIONInventors: Alexsandr Juk, Alain Ross, Takashi Miyasaka, Takeya Tsukamoto, Shigeya Kikuta

Patent number: 7477977Abstract: A power window device for use in a vehicle for raising and lowering each window glass. The power window device includes a drive unit for each door operable for raising and lowering the associated window glass. Each drive unit includes an EEPROM for retaining mounting position information of the position in the vehicle at which the window glass driven by the associated drive unit is located. A processor in each drive unit retrieves steering wheel position information of whether the steering wheel is located in the right or left side of the vehicle. The processor recognizes the position in the vehicle at which the associated drive unit is installed based on the mounting position information and the steering wheel information. This enables the drive unit to be used for both right hand and left hand drive vehicles.Type: GrantFiled: April 7, 2006Date of Patent: January 13, 2009Assignees: Kabushiki Kaisha Tokai Rika Denki Seisakusho, Aisin Seiki Kabushiki KaishaInventors: Kozo Nishimura, Akira Ogino, Seiichi Watanabe, Takashi Kikuta, Yukio Isomura

Patent number: 7276872Abstract: A power window device for lowering and raising window glasses. A window switch is operated to move a corresponding window glass. A motor drives the window glass when the window switch is operated. An ECU is provided for each window glass to control the motor in accordance with the operation of the window switch. An engine switch shifts positions to drive an engine. A control signal generator generates a signal to validate or invalidate control of the ECU over the motor. A control circuit determines that a signal wire connecting the ECUs to the control signal generator is in an unexpected condition when a signal cannot be received. The control circuit overrides the signals generated by the control signal generator when the signal wire is in an unexpected condition.Type: GrantFiled: December 19, 2005Date of Patent: October 2, 2007Assignees: Kabushiki Kaisha Tokai Rika Denki Seisakusho, Aisin Seiki Kabushiki KaishaInventors: Kozo Nishimura, Seiichi Watanabe, Masahiro Kasai, Takashi Kikuta, Yukio Isomura
