Patent number: 10505407Abstract: A brushless motor comprising: a rotor; a stator core disposed at a radial direction outside of the rotor, and a stator case. The stator core includes an outer ring shaped section, teeth sections projecting out from the outer ring shaped section toward a radial direction inside, and an inner ring shaped section extending from end portions of the teeth sections. Protruding portions are formed at the outer ring shaped section so as to project toward a radial direction outside and so as to be disposed at even intervals around a circumferential direction of the outer ring shaped section. The stator case is integrated together with the stator core by a plurality of plastic deformation portions formed at an outer peripheral portion of the stator case at locations facing towards the protruding portions, and the plastic deformation portions are disposed at even intervals along a circumferential direction of the stator case.Type: GrantFiled: February 8, 2017Date of Patent: December 10, 2019Assignee: DENSO CORPORATIONInventors: Yoshinobu Nagao, Satoru Suzuki, Takashi Nagaya, Yoshihiro Adachi, Yukihide Ishino, Yoshitsugu Nakagawa, Masaru Irie, Toshihiro Matsuura

Patent number: 9593720Abstract: A motor includes a motor body, a pin, a core, and an input cam. The motor body includes a housing and an output shaft. The pin is arranged in the output shaft to extend in a direction orthogonal to a rotation axis of the output shaft. The core is pivotally supported by the pin and rotates coaxially with the output shaft. The input cam is annular and surrounds an outer circumference of the core. The input cam rotates integrally with the core. An end surface of the core closer to the housing includes a first deviated surface. The core includes an insertion portion into which the pin is inserted. When a center axis of the core is coaxial to the rotation axis of the output shaft, the first deviated surface is located at a position farther from the housing than the insertion portion.Type: GrantFiled: March 6, 2015Date of Patent: March 14, 2017Assignees: ASMO CO., LTD., Denso CorporationInventors: Yoshiyasu Inoue, Nobuhiro Matsumoto, Masanori Ozaki, Hirokazu Tajima, Masaru Irie, Taei Sugiura

Patent number: 9453508Abstract: An electric oil pump is coupled to a pump receptacle including an oil inflow passage and an oil outflow passage. The electric oil pump includes a motor, a pump rotor, a housing, and a check valve. The housing accommodates the motor and the pump rotor. The housing closes an opening of the pump receptacle and includes at least a fitted portion fitted into the pump receptacle. An oil compartment is formed between the pump receptacle and the housing. Oil flows into the oil compartment from the oil inflow passage when the pump rotor is rotated. The fitted portion is partially immersed in the oil collected in the oil compartment. The housing includes a suction port and a discharge port. A check valve, located in the housing, limits reversed flow of the oil from the oil compartment to the oil inflow passage.Type: GrantFiled: February 20, 2014Date of Patent: September 27, 2016Assignee: Asmo Co., LTD.Inventors: Mototsugu Suzuki, Masaru Irie

Patent number: 9334926Abstract: In a drive force transmission apparatus, when an input shaft is rotated in a normal rotational direction, a rotational force of the input shaft is transmitted to an output shaft through a one-way clutch to rotate the output shaft at a rotational speed, which is the same as a rotational speed of the input shaft. At this time, an input side sub-shaft is freed from an output side sub-shaft. In contrast, when the input shaft is rotated in a reverse rotational direction, the rotational force of the input shaft is transmitted to the output shaft through an input gear, a first gear, the input side sub-shaft, a two-way clutch, the output side sub-shaft, a second gear and an output gear. At this time, the output shaft is freed from an intermediate shaft.Type: GrantFiled: January 16, 2012Date of Patent: May 10, 2016Assignee: DENSO CORPORATIONInventors: Yuuya Takahashi, Yasuyoshi Suzuki, Hiroki Ozaki, Masaru Irie, Yoshiyasu Inoue, Takashi Kawasaki

Publication number: 20150222152Abstract: A motor includes a stator, a rotor, and a case. The stator includes a stator core and windings. The rotor is provided inside the stator. The rotor includes first and second rotor cores and a field magnet. The first and second rotor cores each includes a core base and claw-shaped magnetic poles. The core bases are opposed to each other and the claw-shaped magnetic poles of the first and second rotor cores are alternately disposed in a circumferential direction. The field magnet is disposed between the core bases in the axial direction. The field magnet is magnetized in the axial direction so as to cause the claw-shaped magnetic poles of the first rotor core and the second rotor core to function respectively as first magnetic poles and second magnetic poles. At least part of an end part of the case in the axial direction is made of a non-magnetic body.Type: ApplicationFiled: January 23, 2015Publication date: August 6, 2015Applicant: ASMO CO., LTD.Inventors: Yoji Yamada, Takahiro Tsuchiya, Chie Morita, Koji Mikami, Seiya Yokoyama, Masaru Irie

Patent number: 8258490Abstract: Prior to applying of ultraviolet rays to a surface of a wafer with a protective tape joined thereto that is placed and held on a holding table, an illumination sensor moves to a position below an ultraviolet irradiation unit having ultraviolet light emitting diodes arranged in one dimensional array to measure ultraviolet intensity in a position corresponding to a surface of the protective tape, and output voltage of each diode is controlled so as to maintain a uniform accumulated quantity of light in an area of the protective tape where ultraviolet rays are applied that is determined from the result of measurement and a turning velocity of the holding table.Type: GrantFiled: April 27, 2010Date of Patent: September 4, 2012Assignee: Nitto Denko CorporationInventors: Masayuki Yamamoto, Masaru Irie

Publication number: 20110139375Abstract: An adhesive tape joined to a wafer is irradiated with ultraviolet rays via diodes. Simultaneously, a heater heats the adhesive tape to a preset temperature. Consequently, an ultraviolet reaction with the diodes and an infrared reaction with the heater may ensure promotion of a polymerization reaction, which results in cure of an adhesive that is not curable with only ultraviolet rays. As a result, an adhesive force of the adhesion tape may sufficiently be reduced. After ultraviolet irradiation via the diodes and heating with the heater, a separation mechanism separates the adhesive tape from the wafer. Therefore, accurate separation may be realized of the adhesive tape joined to the wafer.Type: ApplicationFiled: December 13, 2010Publication date: June 16, 2011Inventors: Masayuki Yamamoto, Masaru Irie
