Publication number: 20240051484Abstract: An in-vehicle imaging device includes an impact detecting unit configured to detect an impact on a vehicle, a connection processing unit configured to connect to a first phone contact when the impact detected by the impact detecting unit is equal to or greater than a predetermined magnitude and to set a second phone contact as a destination of a connection when the impact is less than the predetermined magnitude, and an operation detecting unit configured to detect a user's operation. The connection processing unit connects to the second phone contact when the impact is less than the predetermined magnitude and the operation detecting unit detects an operation for connecting to a phone contact.Type: ApplicationFiled: October 24, 2023Publication date: February 15, 2024Inventors: Tomohiro MATSUOKA, Fumihiko YOKOYAMA, Takeshi KUCHINOMACHI, Yasuo SUGITA, Yoshiharu KOJI, Manabu KARASAWA

Publication number: 20170089262Abstract: A lubricating oil line of a gas turbine or a turbocharger includes a flow path component which allows passage of a lubricating oil. The flow path component used in the gas turbine includes a sump chamber and a vent line. A surface of the flow path component, which is exposed to a temperature approximately from 300 to 450° C. and comes into contact with the lubricating oil, is covered with a coating that includes nickel or a nickel-phosphorus alloy, and particles made of polytetrafluoroethylene.Type: ApplicationFiled: December 13, 2016Publication date: March 30, 2017Applicant: IHI CorporationInventors: Fumihiko YOKOYAMA, Yuka KATO

Patent number: 9322313Abstract: The present invention is a deposition prevention method of coking deposits using a turbocharger (120) including a turbine (122) including a flow path section having a vane section, a nozzle, and a housing, and a compressor (124) configured to introduce air into an engine (110) using rotation of the vane section of the turbine, and installed at an exhaust path (202) of the engine. The method includes a film coating process of forming a film including an element having a standard free energy change in a carbonization reaction of ?50 kJ/mol or more on at least one surface of the vane section, the nozzle and the housing of the flow path section of the turbine.Type: GrantFiled: December 26, 2011Date of Patent: April 26, 2016Assignee: IHI CORPORATIONInventor: Fumihiko Yokoyama

Patent number: 9206371Abstract: A bearing grease contains a base oil and a thickener. The base oil is a base oil mixture containing a polyalphaolefin and an ester. The bearing grease is used in an atmosphere of a fluorine compound refrigerant containing no hydrogen. A bearing using the bearing grease does not cause elution of grease for a long time. Further, since there is no need for a collecting system unlike lubricating oil, the arrangement around the bearing can be made compact. Thus, the bearing can be easily applied in a form of an energy recovery equipment to a vehicle or various industrial machineries.Type: GrantFiled: May 31, 2012Date of Patent: December 8, 2015Assignees: IDEMITSU KOSAN CO., LTD., IHI CorporationInventors: Yukitoshi Fujinami, Fumihiko Yokoyama

Patent number: 9062270Abstract: Bearing grease includes an ether base oil and a urea thickener, and is used in an atmosphere of a fluorine compound-based refrigerant. No grease is eluted for a long period in a bearing with use of the bearing grease. Moreover, since a collection system is unnecessary unlike a lubricating oil, the surroundings of the bearing can be made compact. Accordingly, the bearing with use of the bearing grease is easily applicable to automobiles and a variety of industrial machinery as an energy collection apparatus using the Rankine cycle.Type: GrantFiled: December 27, 2011Date of Patent: June 23, 2015Assignees: IDEMITSU KOSAN CO., LTD., IHI CorporationInventors: Yukitoshi Fujinami, Fumihiko Yokoyama
