Patent number: 11302968Abstract: A first electrode sheet includes respective active material layers on a first face of a positive electrode metal foil and an opposing second face. The first face active material layer includes a parallel section along the first face, a tapered section between a positive electrode first lateral side of the first face and a first face parallel section and inclined inward towards a current collector inner region relative to a thickness direction of the first face active material layer, and a curved section forming a curved surface between and across the first face parallel and the first face tapered sections. A separator includes a first separator covering the side of the positive electrode metal foil first face, and a second separator covering the side of the second face. A first separator part lying flush against and contacting the first face tapered section arranged along the first face tapered section.Type: GrantFiled: November 16, 2016Date of Patent: April 12, 2022Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Atsushi Minagata, Yasuyuki Goda, Shinya Asai, Hiroyasu Nishihara

Publication number: 20180226687Abstract: An electrode assembly is an electrode assembly of a lithium ion secondary battery in which sheet-like positive electrodes and sheet-like negative electrodes are alternately stacked, with bag-like separators interposed therebetween. The area of the first main surface of each of the positive electrodes is smaller than the area of the first main surface of each of the negative electrodes, and the area of the second main surface of each of the positive electrodes is smaller than the area of the second main surface of each of the negative electrodes. The first main surfaces of the positive electrodes and the negative electrodes are opposed to each other, with the respective bag-like separators interposed therebetween, and the second main surfaces of the positive electrodes and the negative electrodes are opposed to each other, with the respective bag-like separators interposed therebetween.Type: ApplicationFiled: July 20, 2016Publication date: August 9, 2018Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Shinya ASAI, Atsushi MINAGATA, Hiroyasu NISHIHARA, Yasuyuki GODA

Patent number: 9446938Abstract: A capacitance type physical quantity sensor includes: a first substrate; and a second substrate bonded to the first substrate through an insulating film. The second substrate includes first and second groove portions at a place of the second substrate facing an end portion of the first and second support units formed on the first substrate on a side opposite to the movable unit. A part of the end portion of the first support unit protrudes over the first groove portion. A part of the end portion of the second support unit protrudes over the second groove portion.Type: GrantFiled: April 24, 2014Date of Patent: September 20, 2016Assignee: DENSO CORPORATIONInventors: Tetsuo Yoshioka, Shinya Asai, Jyunya Nishida

Publication number: 20140319967Abstract: The oscillation actuator of the invention uses ultrasonic vibrations generated in a stator to rotate a rotor, and a pre-load member causes a 30 MPa contact pressure between the rotor and the stator. Furthermore, a supply body impregnated with oil is provided inside a recess section in the stator, such that the contact section between the rotor and the stator is lubricated by oil supplied from the supply body. As the oil with which the supply body is impregnated, a fluorine-based oil having a kinetic viscosity at 40° C. of VG 400 according to the ISO viscosity classification is selected.Type: ApplicationFiled: December 7, 2012Publication date: October 30, 2014Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Shinya Asai, Masaki Takasan, Akihiro Suzuki, Yasuyuki Goda, Wataru Makishi

Publication number: 20140312738Abstract: A rotor 2 of an ultrasonic motor 1 is pressed to make contact with a pair of supporting parts 11, 12 of a stator 3. Contact surfaces 21, 22 are formed respectively following the shape of an outer circumferential surface 2b of the rotor 2, in the upper portions of the supporting parts 11, 12. Since different level sections 23, 25 are formed in the contact surface 21, and different level sections 24, 25 are also formed in the contact surface 22, the contact distance between the rotor 2 and the stator 3 is limited.Type: ApplicationFiled: July 30, 2012Publication date: October 23, 2014Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Akihiro Suzuki, Shinya Asai, Masaki Takasan, Kanji Erami
