Patent number: 6628798Abstract: In a vibration actuator using a magnetic circuit device (14), a supporting arrangement (23) elastically supports the magnetic circuit device. A coil (17) is inserted into a magnetic gap (15) of the magnetic circuit device and is supported by a vibration plate (19). The vibration actuator has a first operation mode in which the magnetic circuit device mainly vibrates to transmit vibration through the vibration plate to the outside, a second vibration mode in which the coil mainly vibrates to produce a buzzer sound through the vibration plate, and a third vibration mode in which the magnetic circuit device and the coil mainly vibrate to produce a sound corresponding to a speech through the vibration plate.Type: GrantFiled: April 11, 2000Date of Patent: September 30, 2003Assignee: NEC Tokin CorporationInventors: Makoto Teshima, Koji Uchida, Yutaka Suzuki, Toru Kumagai

Patent number: 6163300Abstract: In a multi-band antenna (10) being provided with an antenna element having an LC parallel resonance circuit (3) and a first and a second radiation element (1,2) connected to opposite ends of the LC parallel resonance circuit, the LC parallel resonance circuit is constituted by self-resonance of an inductor itself. A telescopic whip antenna may be constituted by combining a small-size antenna and a whip antenna which is receivable in a radio device casing and expandable.Type: GrantFiled: July 23, 1998Date of Patent: December 19, 2000Assignee: Tokin CorporationInventors: Shigekazu Ishikawa, Makoto Teshima, Masashi Ikeda, Kazuo Minegishi

Patent number: 5047940Abstract: Slip control is carried out so as to reduce torque applied to the driven wheels by reducing torque generated by the engine when a slip value against the driven wheels on pavement is larger than a predetermined value. A shift characteristic of the automatic transmission interposed between the engine and the driven wheels is set as a first shift characteristic which is a basic characteristic at the time of ordinary running where no slip control is carried out and as a second shift characteristic set so as to become at least unlikely to cause downshifting during slip control compared with said first shift characteristic. As the slip control terminates, a return of the first shift characteristic is prohibited when the torque generated by the engine is large (for example, when a degree of operation of an accelerator is not zero) or when downshifting is caused if based on the first shift characteristics.Type: GrantFiled: June 7, 1989Date of Patent: September 10, 1991Assignee: Mazda Motor CorporationInventors: Toru Onaka, Toshiaki Tsuyama, Kazutoshi Nobumoto, Fumio Kageyama, Akira Sone, Makoto Teshima
