Publication number: 20060154683Abstract: A communication method and a communication system which enable a user to swiftly send a standard voice message or sound to one or more other communication perties during a conversation, and also simultaneously send a voice message to a plurality of other communication parties. A user can swiftly transmit a standard voice message or sound previously stored in his/her communication terminal even during a conversation. Thus, the other communication party who has the conversation with the user can listen to the message or sound instead of the user's voice. Further, when there are a plurality of other communication parties, a voice message can be simultaneously sent thereto.Type: ApplicationFiled: January 6, 2006Publication date: July 13, 2006Inventors: Yohei Umezawa, Yasushi Toda

Patent number: 6607112Abstract: There is provided a wire bonding apparatus operated steadily at a high speed without excitation of vibrations of an XY stage 102 and a capillary 104, which are movable parts. The wire bonding apparatus is configured so as to have a composite target path generating section 208 for generating a target path 109, in which the deceleration part of a go path and the acceleration part of a return path are composed to one continuous path, for a path part of reciprocating movement of said target path indicating a motion process of either one or both of the XY stage and capillary.Type: GrantFiled: August 2, 2001Date of Patent: August 19, 2003Assignee: NEC CorporationInventor: Yasushi Toda

Patent number: 6377522Abstract: A defined level comparator compares a track error signal with each of a predetermined upper limit level and a predetermined lower limit level so as to generate two comparison signals. A logic unit ANDs two comparison signals so as to obtain a track pull-in enabling signal. A header component removal arithmetic unit removes a header component from the track pull-in enabling signal in accordance with a header area signal. A track polarity inverter outputs a land/groove detection signal in which a polarity of a signal level is inverted every timing at which a signal level of the track pull-in enabling signal is in a track pull-in enabling state. A track polarity correcting and determining unit compares a polarity signal held by a sampling holder with the land/groove detection signal in the header area.Type: GrantFiled: December 17, 1999Date of Patent: April 23, 2002Assignee: NEC CorporationInventor: Yasushi Toda

The wire bonding apparatus is configured so as to have a composite target path generating section 208 for generating a target path 109, in which the deceleration part of a go path and the acceleration part of a return path are composed to one continuous path, for a path part of reciprocating movement of said target path indicating a motion process of either one or both of the XY stage and capillary. Therefore, the period of a composite target acceleration path can be set long while the required time until the end of path is shortened, and the wire bonding apparatus can be operated steadily at a high speed without excitation of vibrations of the XY stage and capillary, which are movable parts.Type: ApplicationFiled: August 2, 2001Publication date: February 7, 2002Applicant: NEC CORPORATIONInventor: Yasushi Toda

Patent number: 6124845Abstract: A cursor control device is provided which has good operability and can reflect clearly an operator's natural motion in accordance with a qualified value (conversion coefficient). The cursor control device is constituted of an operation plate 5 with an operation surface 7, an operation pressure detecting detector with a pressure-sensitive sensor 3 arranged on the back surface of the operation plate 5 to detect a touch pressure by a control member, and an arithmetic circuit. The arithmetic circuit performs an arithmetic operation of both the coordinate position and the moving rate of the control member using a detection signal from the operation pressure detection detector, and the movement of a cursor based on a first qualified value and a second qualified value. The first qualified value is determined according to the movement and the moving rate of a coordinate position. The second qualified value is determined according to the touch pressure of the control member.Type: GrantFiled: January 27, 1997Date of Patent: September 26, 2000Assignee: Alps Electric Co., Ltd.Inventors: Yasushi Toda, Hideki Suzuki

Patent number: 5448570Abstract: A communication system that performs time-division multiple access mobile communication using radio in a service area in which are disposed a plurality of base stations connected to a central station through a communication network. The central station selects and designates a master base station and a selected base station close to the master base station. The central station instructs the selected base station to synchronize a radio signal transmitted by the selected base station with a radio signal transmitted by the master base station. The central station further selects at least one additional base station close to the selected base station. The central station instructs the at least one additional base station to synchronize a radio signal transmitted by the additional base station with a radio signal transmitted by the selected base station. The process is repeated until all of the base stations are transmitting a synchronized radio wave.Type: GrantFiled: March 16, 1994Date of Patent: September 5, 1995Assignee: Kyocera CorporationInventors: Yasushi Toda, Tetsuya Yuda
