Patent number: 9834247Abstract: A connector unit of a drive device includes an electric power supply connector, a signal connector, a base portion and leg portions and is fixed to an opposite side of a heat sink, which is opposite from an electric motor. The leg portions are formed at an outer peripheral edge of the base portion. A cover member receives the connector unit and the heat sink in the state where the electric power supply connector and the signal connector are exposed from the cover member. A connector side O-ring is installed between the base portion and the cover member. A height position of a first end surface of each leg portion is on a first side of a second base end surface of the base portion. With this construction, it is possible to limit deterioration of waterproofness of the drive device caused by a thermal load.Type: GrantFiled: November 29, 2016Date of Patent: December 5, 2017Assignee: DENSO CORPORATIONInventors: Tatsuya Abe, Yasufumi Matsuo, Shuhei Miyachi

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

Publication number: 20140145564Abstract: A housing and a rotary shaft of a motor are formed of non-magnetic material. A soft magnetic member is provided between a first axial end surface of a fixed core and a bearing. The soft magnetic member is provided on the fixed core side relative to the first bearing thereby to suppress magnetic flux leaking to a vicinity of one end part of the rotary shaft by leading the magnetic flux, which is generated from a rotor, to the rotor core through the fixed core and a casing. A magnetic angular position sensor fixed to one end part of the rotary shaft can detect a magnetic angular position of the rotor accurately without being affected by external magnetic field. As a result, noise generated by vibration of the motor can be suppressed.Type: ApplicationFiled: September 16, 2013Publication date: May 29, 2014Applicant: DENSO CORPORATIONInventors: Makoto TANIGUCHI, Jirou HAYASHI, Tatsuya INAGAKI, Akihito NAITOU, Hiroki TOMIZAWA, Masaaki YAMADA, Masashi YAMASAKI, Yasufumi MATSUO, Shuhei MIYACHI, Nobuhiko URYU

Publication number: 20120070361Abstract: Disclosed is a method for collecting hexachlorodisilane which is produced as a by-product in the production of trichlorosilane from tetrachlorosilane and hydrogen. The method has the steps of: reacting a source gas composed of vaporized trichlorosilane and hydrogen at a temperature ranging from 700 to 1400° C. to yield a reaction product gas; cooling the reaction product gas to a temperature ranging from 30 to 60° C. to yield a cooled condensate liquid containing hexachlorodisilane; and concentrating and collecting a high boiling material containing hexachlorodisilane from the cooled condensate liquid.Type: ApplicationFiled: March 30, 2009Publication date: March 22, 2012Applicant: DENKI KAGAKU KOGYO KABUSHIKI KAISHAInventors: Yasufumi Matsuo, Kouichi Takemura, Shin Sugimura

Patent number: 7017755Abstract: Rear ends of pushing rods 40 are axially connected to a support base 50, which is movably engaged with guide rails 60. A drive unit 70 is disposed to rotatably move wire belts 74 between wheels 73 and 71 at longitudinal front and rear ends of the guide rails 60, and the support base 50 is connected to the wire belts 74. The drive unit 70 is activated to guide the pushing rods 40 by the guide rails 60 so to make pushing and pulling operation of the pushing rods 40. A door 33 which is disposed at the back wall of a static grate 31 in a clinker cooler 30 is opened to fit the pushing rods 40 into a seal material 34 on the opening to push a large lump of coating C2 retained on the static grate 31. The pushing rods 40 have a double tube structure and are cooled by injecting cooling water from supply pipes 45.Type: GrantFiled: May 31, 2000Date of Patent: March 28, 2006Assignee: Denki Kagaku Kogyo Kabushiki KaishaInventors: Masura Nakamura, Tsuyoshi Yamamoto, Asaaki Nishioka, Shigetoshi Toyooka, Yasufumi Matsuo, Shunichi Nagasaki
