Publication number: 20240103414Abstract: A fixing unit or device that can be used in an image forming apparatus includes a first heater element that is formed of a material that increases in electrical resistance with increases in temperature. A controller of the fixing unit is configured to vary a duty ratio of electric power applied to the first heater element during a start-up operation in which the temperature of the first heater element is raised to a target operating temperature. By varying the duty ratio during the start-up operation, changes in the resistance of the first heater element with the heating can be compensated. For example, the duty ratio can be increased during the course of the start-up to achieve the target operating temperature faster.Type: ApplicationFiled: December 1, 2023Publication date: March 28, 2024Inventors: Kiyotaka MURAKAMI, Kazuhiko KIKUCHI, Sasuke ENDO, Masaya TANAKA, Ryota SAEKI, Kousei MIYASHITA, Ryosuke KOJIMA, Yohei DOI, Yuki KAWASHIMA, Eiji SHINOHARA

Patent number: 11510581Abstract: A blood pressure measurement method includes wrapping a cuff around a site. The cuff includes: a first bladder that swells due to receiving fluid and is arranged at an outer surface of the site that corresponds to a first half surface where an artery is; and a second bladder that swells due to receiving fluid and is arranged at the outer circumferential surface of the measurement site that corresponds to a second half surface opposite to the first half surface. During inflation, the pressure of the second bladder is made larger than the first bladder by supplying more fluid such that the stroke amount by which the second fluid bladder swells is larger in the thickness direction. Then, the two bladders are inflated at equal rates. In the process of inflating, or in the process of deflating at rates equal to each other after inflating, blood pressure is measured.Type: GrantFiled: July 1, 2019Date of Patent: November 29, 2022Assignee: OMRON HEALTHCARE Co., Ltd.Inventors: Yoshihide Tokko, Ryosuke Doi, Hiroshi Koshimizu, Kenji Ono

Patent number: 10393557Abstract: Degradation of reliability of a thermal fluid flow sensor, caused by generation of a crack in an insulating film is prevented in the thermal fluid flow sensor including a detection section and a circuit section formed on the same substrate when stress adjustment is performed by forming a deep concave portion in an interlayer insulating film in the detection section and forming the insulating film having a tensile stress thereon. As a means thereof, stair-like step is provided in a side wall of a concave portion, formed in the interlayer insulating film on a diaphragm. Accordingly, each depth of a first concave portion and a second concave portion, which form the concave portion, is reduced, and coatability of the insulating film for the stress adjustment, which covers a side wall and a bottom face of the concave portion, is improved.Type: GrantFiled: November 26, 2015Date of Patent: August 27, 2019Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Noriyuki Sakuma, Yasuo Onose, Shinobu Tashiro, Ryosuke Doi
