Publication number: 20160217971Abstract: The purpose of the present invention is to provide a charged particle beam device and a sample holder for the charged particle beam device by which it is possible to form various environments, and perform in-situ observation and analysis without removing a sample from the charged particle beam device. In the present invention, inserting a detachable reverse side entry portion from a side facing a sample holding means, said portion being provided with a function for changing the state of a sample attached to the sample holding means, makes it possible to observe/analyze changes in the sample by a different process without removing the sample from the charged particle beam device by combining a reverse side entry portion having a different function with the sample holding means. The reverse side entry portion comprises two parts, and a tip thereof, which is one of the parts, is removable.Type: ApplicationFiled: September 5, 2014Publication date: July 28, 2016Inventors: Toshie YAGUCHI, Yasuhira NAGAKUBO, Toshiyuki IWAHORI

Patent number: 9144476Abstract: A three-axis acceleration sensor is mounted to a body of an electric toothbrush. A CPU detects the three-dimensional attitude of the body based on an output from the acceleration sensor and, based on the attitude of the toothbrush, estimates which portion is being brushed. Then, the CPU performs control for switching between operation modes (such as the rotational direction of a motor and the frequency of vibration of the brush) according to the estimated portion being brushed.Type: GrantFiled: March 9, 2009Date of Patent: September 29, 2015Assignee: OMRON HEALTHCARE CO., LTD.Inventors: Toshiyuki Iwahori, Akitoshi Miki

Publication number: 20140207388Abstract: A urine component analysis device with a correlation storage section stores data indicating a correlation between a measured concentration of a specific component in human urine and measured concentration of the specific urine component in one day. A data input section inputs data indicating concentration of the specific component in one subject's urine. A concentration of the specific component in total urine of the subject in one day is determined by conversion using the correlation storage section based on the concentration of the specific component in the urine. A total urine amount acquirement section acquires total amount of urine excreted by the subject in one day based on conversion or database. An excretion amount of the specific component in total urine of the subject in one day is calculated by multiplying the concentration of the specific component in total urine in one day, by the acquired total urine amount.Type: ApplicationFiled: February 5, 2014Publication date: July 24, 2014Inventors: Hideyuki YAMASHITA, Naoto OHGAMI, Toshiyuki IWAHORI, Hirotsugu UESHIMA

Publication number: 20140150535Abstract: In a urine component analysis device, a correlation storage section stores data indicating a correlation between a measured concentration in one urine and in total urine in one day for each of a first and second specific component in the urine excreted by a human. A data input section inputs data indicating a concentration of the first specific component and of the second specific component in one urine of a subject. A concentration of the first specific component and of the second specific component in total urine in one day are determined by performing conversion using the correlation stored in the correlation storage section based on the concentration of the first specific component and the second specific component in the one urine. A concentration ratio between the first specific component and the second specific component in total urine in one day is determined based on the results of conversion.Type: ApplicationFiled: February 5, 2014Publication date: June 5, 2014Inventors: Hideyuki YAMASHITA, Naoto OHGAMI, Yutaro OKUNO, Toshiyuki IWAHORI, Hirotsugu UESHIMA

Patent number: 8479341Abstract: An electric toothbrush includes bristles, a bristle driving unit, an orientation detection sensor, and an electrode-based contact detection unit for detecting contact with a body. The contact detection unit includes a first detection unit for detecting contact with or proximity to a rear surface side of a brush portion. The electric toothbrush detects orientation information based on an output from the orientation detection sensor, and estimates a brushing area based on at least the orientation information. In the area estimation, in the case where the brushing area determined based on the orientation information is a dentition surface on a right buccal side or a left lingual side or a dentition surface on a left buccal side or a right lingual side, it is determined whether the brushing area corresponds to the buccal side or the lingual side based on an electric signal obtained from the first detection unit.Type: GrantFiled: June 7, 2012Date of Patent: July 9, 2013Assignee: Omron Healthcare Co., Ltd.Inventor: Toshiyuki Iwahori

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
