Patent number: 8468634Abstract: An electric toothbrush includes a driving source, a vibrating member having a brush, a transmission mechanism for converting output of the driving source into vibration of the vibrating member, and control means for controlling output of the driving source. The control means has a plurality of operation modes for allowing the brush to perform a predetermined operation. The plurality of control modes are switched at high speed to allow brushing using a transient state at a time of operation mode switching. It is suitable to switch at high speed between operation modes using two resonance points in which resonance occurs in different directions. Accordingly, the electric toothbrush is improved in plaque removing power and sense of medical treatment.Type: GrantFiled: March 16, 2009Date of Patent: June 25, 2013Assignee: OMRON Healthcare Co., Ltd.Inventors: Toshiyuki Iwahori, Jun Shimoyama

Patent number: 5224492Abstract: In a CT image of a living body, contours of internal organs thereof are discriminated. Parameters are beforehand stored in a memory for a plurality of internal organs of the living body. Applicators are attached onto the living body and then a high frequency power is applied to electrodes disposed therein so as to heat an internal portion of the body. Based on an intensity of an electric field generated in the body due to the applied power and the parameters stored in the memory, a temperature distribution on the CT image is estimated. To retain an estimated temperature of an objective tumor at a predetermined target temperature, the high frequency power and the cooling water in the applicators are controlled. In the estimation of the temperature distribution, the parameters of the living body are repeatedly corrected to minimize a discrepancy between a temperature measured at a preset position and an estimated temperature associated therewith.Type: GrantFiled: June 11, 1991Date of Patent: July 6, 1993Assignee: Omron CorporationInventors: Noriyuki Takahashi, Tamaki Sakamoto, Jun Shimoyama, Eiji Kasai, Makoto Saito, Jin-ichi Matsuda, Kazuo Kato
