Publication number: 20240088287Abstract: A semiconductor device includes a semiconductor substrate, a first insulating film formed on an upper surface of the semiconductor substrate in an outer peripheral region so as to surround a cell region in plan view, and a resistive element formed on the first insulating film so as to surround the cell region in plan view. A second insulating film having a thickness thinner than that of the first insulating film is formed on the upper surface of the semiconductor substrate in the outer peripheral region. A dummy pattern is formed from a portion over the second insulating film to a portion over the first insulating film so as to cover a step occurring between the second insulating film and the first insulating film.Type: ApplicationFiled: July 5, 2023Publication date: March 14, 2024Inventors: Takahiro OHARA, Koichi ARAI, Yasunori YAMASHITA, Hideyuki YASHIMA

Patent number: 11903481Abstract: The plaque detecting device of the present invention comprises a light emitting unit (450) which irradiates ultraviolet or blue excitation light (L) toward the tooth surface (99a), and a first and second light receiving units (402) which receive radiated light (L?) from the tooth surface (99a). The first light receiving unit extracts the spectral component of a first wavelength region including the wavelength range of fluorescent light specific to plaque from the radiated light (L?), and obtains a first output value corresponding to the intensity of that spectral component. The second light receiving unit extracts, from the radiated light (L?), the spectral component of a second wavelength region containing the wavelength range of the fluorescent light specific to enamel and having a predetermined lower limit wavelength below the lower limit wavelength of the first wavelength region, and obtains a second output value corresponding to the intensity of this spectral component.Type: GrantFiled: January 17, 2022Date of Patent: February 20, 2024Assignees: Colgate-Palmolive Company, Omron Healthcare Co., Ltd.Inventors: Hideyuki Yamashita, Kosuke Abe, Hideaki Yoshida, Yasuhiro Kawabata, Masashi Kitamura

Publication number: 20230200669Abstract: In the present invention, a blood pressure measuring cuff is worn around a rod-shaped site to be measured of a subject in a circumferential direction. A light projecting unit is disposed only along an edge portion on one side or both sides of the cuff in a width direction, and irradiates a periphery of a target region of the site to be measured with light. A light receiving unit is provided in a sheet shape along a specific portion facing the target region on an inner surface of the cuff, and receives light scattered or reflected by the target region to obtain an image including a vein pattern of the target region. An authentication unit compares the vein pattern with a reference vein pattern registered in advance, and performs the vein authentication on the subject.Type: ApplicationFiled: March 6, 2023Publication date: June 29, 2023Applicant: OMRON HEALTHCARE CO., LTD.Inventors: Tatsuya KOBAYASHI, Hideyuki YAMASHITA, Maya MAKITA
