Publication number: 20120294454Abstract: A mobile phone apparatus 10 is provided with a five conductor earphone jack 26, etc. which is used to be shared between four and five conductor earphone plugs. Also, the two plugs have a left audio terminal at the same position, but a right audio terminal and a GND terminal at opposite positions. When the earphone plug is inserted, a tone signal is output from a third jack terminal. At this time, if the four conductor earphone plug is inserted, a tone signal is output as a leakage signal from a first jack terminal through a four conductor earphone. Then, the leakage signal is amplified, and input to a controlling circuit (70). On the other hand, if the five conductor earphone plug is inserted, a leakage signal is not output.Type: ApplicationFiled: May 19, 2012Publication date: November 22, 2012Applicant: KYOCERA CORPORATIONInventors: Yasuyuki SAKAMOTO, Yoshiomi KUSUNOKI

Patent number: 7399098Abstract: The present invention is configured so that one light emission source such as a light emitting diode is placed inside an operation knob in front of a light guiding piece or in a bearing of the operation knob. A light beam from the light emission source is emitted to the interior of the operation knob. A reflected indirect light irregularly reflected inside the operation knob is received by the light guiding piece located at a rear surface of the operation knob. The light guiding piece has a transmission and diffusion function. The light is then guided toward an outer periphery to illuminate the rear surface of the operation knob.Type: GrantFiled: April 19, 2004Date of Patent: July 15, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroshi Nakamoto, Yasuyuki Sakamoto, Tomoki Sakamoto, Kiyotaka Matsuura

Patent number: 6454522Abstract: An impeller for a circumferential current pump is provided with a plurality of vanes, and each of the vanes has an upstream side surface and a downstream side surface in a rotating direction thereof and a center line between both these surfaces extends along a radial direction of a disc-shape member, the upstream side surface has a radially inside portion and a radially outside portion which are formed to be continuous so that the radially inside portion is in parallel to the center line and the radially outside portion is inclined forward in the rotating direction of the disc-shape member, and the downstream side surface is formed entirely to be parallel to the center line.Type: GrantFiled: March 29, 2001Date of Patent: September 24, 2002Assignee: Enplas CorporationInventors: Yasuyuki Sakamoto, Naotaka Tatsuzawa

Patent number: 6443692Abstract: An impeller for a circumferential current pump is injection molded and can be used as it is without being polished. The impeller (7) is provided with a plurality of vane grooves (12) on an outer periphery of a synthetic resin disc-like member (8) rotated by a motor, and is rotatably received with a substantially disc-like space (6) formed between a pump casing (4) and a pump cover (5). A disc-like recess portion (14) is formed in both side surfaces (10, 11) of the disc-like member (8). A formation is performed so that a ratio (L/2t) between the sum (t1+t2=2t) of a gap (t1) between one side surface (10) and the pump casing (4) and a gap (t2) between another side surface (11) and the pump cover (5), and a size (L=R0−H−R1) obtained by subtracting a radical groove length (H) of the vane groove (12) and a radial size (R1) of the recess portion (14) from a radial size (R0) of the disc-like member (8) satisfies a relation 66≦(L/2t).Type: GrantFiled: October 27, 2000Date of Patent: September 3, 2002Assignee: Enplas CorporationInventors: Yasuyuki Sakamoto, Naotaka Tatsuzawa, Yoichi Takeuchi

Patent number: 5625949Abstract: A method of securing to an operating lever in the form of an elongated metal plate an operating button made of thermoplastic resin and including a mounting tongue of a generally tubular configuration having a hollow defined therein. An anchor perforation and a stopper pawl are first formed in the operating lever and the operating button is then temporarily mounted on the operating lever with the operating lever slid into the hollow of the mounting tongue until an abutment defined in the mounting tongue and positioned within the hollow is brought into engagement with the stopper pawl.Type: GrantFiled: January 25, 1995Date of Patent: May 6, 1997Assignees: Matsushita Electric Industrial Co., Ltd., Katani Sangyo Co., Ltd., Seidensha Electronics Co., Ltd.Inventors: Kiyonori Ishida, Tomotaka Orita, Toshiyuki Hanada, Yasuyuki Sakamoto, Kazunori Shimoyama, Masanori Mizutani, Fumio Orito, Shigeru Ogaya

Patent number: 5194043Abstract: An air conditioner has rotatable first and second deflectors provided in an outlet for discharging conditioned air. The first deflector is rotatable about a substantially horizontal axis so as to variably deflect the conditioned air in vertical directions. The second deflector is rotatable so as to block a breadthwise portion of the outlet while forming an air passage in the remainder breadthwise portion of the outlet. The first and second deflectors are rotatable independently of each other.Type: GrantFiled: December 17, 1991Date of Patent: March 16, 1993Assignee: Hitachi, Ltd.Inventors: Norio Takahashi, Masato Sugita, Seimei Okabe, Kuniyuki Yamada, Kazunari Minami, Yoshimi Inoue, Yasuyuki Sakamoto
