Patent number: 5656095Abstract: A plurality of small bubbles are continuously generated by transmitting to washing water in a vessel, a high frequency ultrasonic wave from an ultrasonic vibrator which generates a high frequency output from a high frequency oscillator and intermittently transmitted low frequency ultrasonic waves from ultrasonic vibrators wherein the intermittent low frequency ultrasonic waves are produced from low frequency outputs from low frequency oscillators for short periods of time. The plurality of small bubbles are destroyed by the intermittent ultrasonic waves and the pressure from the sound of the ultrasonic waves in the washing water is thereby increased and washing performance is improved.Type: GrantFiled: October 27, 1994Date of Patent: August 12, 1997Assignee: Honda Electronic Co., Ltd.Inventors: Keisuke Honda, Toshiaki Miyamoto, Hideo Kouzaka

Patent number: 5448128Abstract: A vibration type driving device in which a piezoelectric element is interposed between a pair of blocks connected to each other by a rod, a part of the surface of the piezoelectric element being covered with an electrode. Application of high frequency voltage to the electrode causes resonance of vertical vibrations and bending vibrations, which is effective to generate elliptical movement of the end surface of the block. The electrode is divided into three or more sections, preferably into four sections. A change-over switch is provided for selecting the electrode sections to be energized in accordance with the direction of the driving force. This permits linear movement of an article in a desired direction.Type: GrantFiled: April 4, 1994Date of Patent: September 5, 1995Assignee: Honda Denshi Kabushiki KaishaInventors: Hiroki Endo, Keisuke Honda

Patent number: 5233274Abstract: A drive circuit is used in a Langevin type ultrasonic bolt-tightening motor in which a motor drive voltage having a given frequency is applied to a piezo-electric element in a stator section, the resulting longitudinal and torsional vibrations being effective to rotate a motor section. The drive circuit has a longitudinal vibration sensor for detecting the longitudinal vibration in the stator section, a torsional vibration sensor for detecting vibration in the stator section and a frequency controller for controlling the frequency of the motor drive voltage such that the phase difference between the detection signals of the longitudinal and torsional vibration sensors becomes 90 degrees so as to provide maximum efficiency. Thus, the frequency of the motor drive voltage can be feedback controlled to maintain an optimum drive frequency despite the varying of the optimum drive frequency due to changes in various factors.Type: GrantFiled: November 29, 1991Date of Patent: August 3, 1993Assignees: Asmo Co., Ltd., Honda Electronics Co., Ltd.Inventors: Yasuyoshi Honda, Masahiko Komoda, Keisuke Honda, Toshiaki Miyamoto, Yukinobu Tomida, Masanori Sato, Ryosuke Suganuma, Hideo Kouzaka
