Patent number: 10340765Abstract: A motor unit is received in a first space of a motor case. A frame contacts an inner peripheral wall of the motor case and is fixed in an inside of the motor case. A cutout, which is formed in at least one of the motor case and the frame, forms a seal groove, which extends in a circumferential direction between the motor case and the frame. A cover covers the seal groove and forms a second space in an inside of the cover. A seal material is received in the seal groove and limits intrusion of liquid, such as water, from an outside of the motor case and the cover into the first space and the second space. In this way, intrusion of the liquid into the first space and the second space can be limited with the seal material provided in the single seal groove.Type: GrantFiled: June 28, 2016Date of Patent: July 2, 2019Assignee: DENSO CORPORATIONInventor: Masashi Yamasaki

Publication number: 20180209922Abstract: The type and/or properties of a substance is identified highly accurately regardless of the thickness of the substance. A data processing apparatus processes counts detected at each of pixels of a photo counting detector in each of a plurality of energy ranges of X-rays. The X-rays are radiated from an X-ray tube, and transmitted through an object. The apparatus calculates an image of the object based on the counts, and sets a region of interest on the image. The apparatus further removes, from the pixel, pixel information showing a background present in the region of interest, and calculates, pixel by pixel, inherent information inherent to the substance, based on the counts detected at each of the respective pixels in each of the energy ranges of the X-rays in the region of interest. The inherent information indicates a transmission characteristic inherent to the X-rays.Type: ApplicationFiled: April 20, 2016Publication date: July 26, 2018Inventors: Tsutomu YAMAKAWA, Shuichiro YAMAMOTO, Yoshiharu OBATA, Masashi YAMASAKI, Masahiro OKADA

Patent number: 9742244Abstract: In a driver device, a controller substrate has a center part on which a rotation angle sensor is attached and an outer periphery portion which is fixed onto a heat sink. The heat sink has a cylinder part extending in an axial direction of the rotation shaft to contact the outer periphery portion of the controller substrate. The cylinder part of the heat sink is continuously formed along an entire periphery and has the same height at all portions. Such configuration provides an even deformation distribution of the cylinder part due to a temperature change, thereby reducing unevenness of heat stress distribution along a substrate plane and decreasing stress applied to the sensor, which facilitates a reduction of a detection error of the sensor.Type: GrantFiled: November 25, 2014Date of Patent: August 22, 2017Assignee: DENSO CORPORATIONInventors: Yasufumi Matsuo, Masashi Yamasaki
