Publication number: 20130119786Abstract: A head of an output shaft of a linear actuator is modified so as to absorb vibrations that may be transmitted between the output shaft and a moving object. A linear actuator has an output shaft with a leading end to which a head is fixed. The head has an O-ring that is fitted thereto, and a part of the O-ring outwardly projects from the head. The O-ring is made of rubber that is softer than the material of the head. The head is contained in a containing space in an attachment, and in this condition, the O-ring contacts an inner circumferential surface of the containing space by deforming.Type: ApplicationFiled: February 23, 2012Publication date: May 16, 2013Applicant: MINEBEA MOTOR MANUFACTURING CORPORATIONInventors: Kazuo MURAMATSU, Katsutoshi SUZUKI

Patent number: 8373920Abstract: A display device includes a pair of insulating substrates facing each other, electrochromic elements, and an electrolyte layer. A plurality of electrodes constituting the electrochromic elements are disposed on an inner surface of one of the insulating substrates so as to be spaced from each other. One of the insulating substrates is formed of a flexible member whose outer surface is an input operation surface. A pair of counter electrodes of an input element are disposed between the pair of insulating substrates, the counter electrodes being spaced from the electrodes of the electrochromic elements when viewed in plan. An input operation is performed by bringing the counter electrodes close to each other or bringing the counter electrodes into contact with each other through pressing of the input operation surface.Type: GrantFiled: July 29, 2011Date of Patent: February 12, 2013Assignee: Alps Electric Co., Ltd.Inventor: Katsutoshi Suzuki

Publication number: 20130010510Abstract: First and second opposing ends are formed in a magnetic path forming member on which a power generation coil is wound. A rotating body has a permanent magnet, a first magnetization member and a second magnetization member. When an operating force does not act on an operating member, an end surface of the first magnetization member is opposed to the first opposing end via a gap and an end surface of the second magnetization member is opposed to the second opposing end via a gap. When the operating member is pressed, the rotating body rotates and when the force to the operating member is released, the operating member and the rotating body return. Since the rotating body and the magnetic path forming member do not come into contact with each other, the force required to operate the operating member is relatively weak and large electromotive force can be obtained.Type: ApplicationFiled: July 6, 2012Publication date: January 10, 2013Inventors: Yuji Inada, Katsutoshi Suzuki
