Patent number: 10229884Abstract: A semiconductor device includes a lead frame. One end portion of the lead frame is disposed outside a case, the other end portion of the lead frame is disposed over a front surface of an insulating board inside the case and near a semiconductor element, and the lead frame is formed in the case. Furthermore, the semiconductor device includes a temperature transducer disposed on a side of the other end portion of the lead frame opposite a laminated substrate and near a side portion of a semiconductor element. As a result, the temperature transducer is disposed near the side portion of the semiconductor element in the semiconductor device. Therefore, the temperature of the semiconductor element is properly detected. In addition, the length in the vertical direction of the case of the semiconductor device is reduced and miniaturization is realized.Type: GrantFiled: August 1, 2017Date of Patent: March 12, 2019Assignee: FUJI ELECTRIC CO., LTD.Inventor: Naoki Saegusa

Patent number: 9397015Abstract: A semiconductor device has an insulating substrate, a semiconductor element which is mounted on the insulating substrate, a hollow casing which surrounds a peripheral edge of the insulating substrate to contain the semiconductor element therein, and a sealing material which is charged into the casing to seal the inside of the casing. The casing has protrusion portions each of which partially protrudes from an upper surface of the casing. Thus, it is possible to provide a semiconductor device in which poor external appearance or lowering of adhesion to a cover can be prevented even when a sealing material is injected up to the vicinity of an upper surface of a casing.Type: GrantFiled: March 9, 2015Date of Patent: July 19, 2016Assignee: FUJI ELECTRIC CO., LTD.Inventors: Naoki Saegusa, Takashi Katsuki

Publication number: 20150026561Abstract: A system and method for displaying a web page prevents an operation error when the contents of display of the web page change. A vehicle-mounted device includes a touch panel and an input processor for performing an input operation corresponding to a position of contact of an indicator with a display screen. A proximity sensor and an indicator detector detects that the indicator has a predetermined positional relationship relative to the screen. A web browser obtains data on the web page, and a rendering engine performs web page display processing, including web page analysis processing and screen layout calculation for the data obtained. A display processor and a display device for displaying the web page subjected to the web page display processing are included. When the indicator has the predetermined positional relationship relative to the display screen, the web page display processing is stopped.Type: ApplicationFiled: May 20, 2014Publication date: January 22, 2015Applicant: Alpine Electronics, Inc.Inventors: Haruhiko Nakatsuji, Naoki Saegusa, Rintaro Kuroda
