Patent number: 8698491Abstract: A position detecting device has an output circuit, which controls voltages of signal lines connecting a power supply and a ground by a power side transistor and a ground side transistor. An output signal line connects a connection point of the signal lines and an output terminal. A first comparator circuit outputs a signal “1” when a current flowing in the line between the power supply and the connection point is larger than a normal current flowing into the ground from the power supply in a normal state. A second comparator circuit outputs a signal “1” when a current flowing in the line between the connection point and the ground is larger than the normal current. When the signal “1” is output from the first comparator circuit or the second comparator circuit, a cutoff circuit turns off a switch disposed in the output signal line.Type: GrantFiled: February 6, 2013Date of Patent: April 15, 2014Assignee: Denso CorporationInventors: Hiroyuki Shintani, Takamitsu Kubota, Yoshiyuki Kono

Patent number: 7915889Abstract: A linear displacement detection apparatus is configured to convert a linear displacement of a shaft into a rotary displacement of a sensor rotor of a rotary displacement sensor so as to detect the linear displacement. A sensor lever is fixed to the sensor rotor and rotatable about an axis of the sensor rotor. A sensor rod is located closer to the shaft than the sensor lever and configured to transmit the linear displacement of the shaft to the sensor lever. A bearing member is located closer to the shaft than the sensor rod and configured to release rocking of the shaft.Type: GrantFiled: September 10, 2008Date of Patent: March 29, 2011Assignees: Denso Corporation, Toyota Jidosha Kabushiki KaishaInventors: Hiroyuki Shintani, Hisataka Okado, Yoshiyuki Kono, Takashi Kawashima, Takamitsu Kubota, Shinji Ikeda

Patent number: 7893688Abstract: A position sensor includes a longitudinally extending permanent magnet member at least two longitudinally extending arc-shaped projecting elements respectively projecting from the opposite ends toward the inside space to confront each other at a distance and a pair of compatible main magnetic sensors disposed in the inside space along the longitudinal axis at an interval so as to generate a pair of output signals when the permanent magnet member shifts along the longitudinal axis. The opposite ends of the permanent magnet member are configured to surround a common inside space and polarized to have opposite magnetic poles so as to provide in the inside space a magnetic field whose magnetic flux density becomes a maximum at a longitudinal center of the inside space and gradually becomes smaller as a position of the inside space shifts from the longitudinal center along a longitudinal axis of the permanent magnet members.Type: GrantFiled: July 29, 2008Date of Patent: February 22, 2011Assignee: Denso CorporationInventors: Takashi Kawashima, Kimio Uchida, Yukinobu Kajita, Tatsuya Kitanaka, Koichiro Matsumoto, Yoshiyuki Kono, Hisataka Okado, Hiroyuki Shintani

Patent number: 7173392Abstract: A second member and a first member are applied with bias force to mechanically engage with each other at one of detent positions defining relative positions therebetween. An electric motor rotating a rotor therein when being supplied with electricity. Rotation of the rotor is transmitted to an output shaft manipulating the first member. A main controller controls the electric motor to switch the one of the plurality of detent positions. A rotor angle detecting unit detects rotor angle of the rotor. An output angle detecting unit detects output angle of the output shaft. The main controller includes a backlash calculating unit that calculates a backlash amount between the rotor and the first member in accordance with at least one of occurrence of a first region, in which change in the output angle is small with respect to change in the rotor angle, and a range of the rotor angle in the first region. The main controller incorporates the backlash amount into the control of the electric motor.Type: GrantFiled: May 19, 2006Date of Patent: February 6, 2007Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Masaaki Shinojima, Tomoyuki Kashiwagi, Kiyoshi Kimura, Hiroyuki Shintani, Masashi Hori
