Patent number: 11967584Abstract: A power semiconductor device includes an insulating substrate on which a first conductor layer is arranged on one surface, a first conductor that is connected to the first conductor layer via a first connecting material, and a semiconductor element that is connected to the first conductor via a first connecting material. When viewed from a direction perpendicular to an electrode surface of the semiconductor element, the first conductor includes a peripheral portion formed larger than the semiconductor element. A first recess is formed in the peripheral portion so that a thickness of the first connecting material becomes thicker than other portions.Type: GrantFiled: November 5, 2019Date of Patent: April 23, 2024Assignee: Hitachi Astemo, Ltd.Inventors: Hiromi Shimazu, Yujiro Kaneko, Toru Kato, Akira Matsushita, Eiichi Ide

Patent number: 11260643Abstract: In order to provide a laminating apparatus that enables a film to be loaded in a reliable and easy manner without a complicated structure, a laminating apparatus 1 includes a sheet feed mechanism unit 10, a film cassette 20, and a press-bonding mechanism unit 30 configured to perform thermal press-bonding while sandwiching a sheet with a pair of films. The laminating apparatus 1 also includes an openable/closable upper unit 5, and employs a configuration in which the upper unit 5 is provided with one pressing roller 31 of a pair of pressing rollers of the press-bonding mechanism unit 30, and an upper member of another mechanism for performing a process in a state where the sheet is sandwiched between the films.Type: GrantFiled: May 26, 2017Date of Patent: March 1, 2022Assignee: LAMI CORPORATION INC.Inventors: Yoshihisa Sugata, Hiromi Matsushita, Katsuyoshi Fujiwara

Patent number: 7118266Abstract: A surface light source device of side light type has a guide plate, a primary light source for supplying illuminating light through an incidence surface, first and second edges at which major surfaces respectively intersect the incidence surface, and one or plural additive members arranged in direct contact with the emission surface and/or the back surface thereon in the vicinity of the first edge and/or the second edge. At least one of the additive members has a shield for preventing illuminating light from being incident to the first or second edge. For example, the shield includes absorptive areas formed on the additive members. Each of the absorptive areas is formed so that each of the absorptive areas crosses the first or second edge. A distal end of a reflector arranged in the primary light source or frame blocks incidence of light to the first and/or second edge. The light incidence block to each edge prevents luminance irregularities in the form of a bright line.Type: GrantFiled: April 5, 2004Date of Patent: October 10, 2006Assignee: Enplas CorporationInventor: Hiromi Matsushita

Patent number: 6504270Abstract: It is an object of the present invention to provide an uninterruptible switching regulator with which smaller size and lower cost can be achieved while the power supply efficiency is raised, which is accomplished by the effective utilization of an RCC type switching circuit. When the commercial AC input power supply 1 is operating normally, the AC-side RCC type switching circuit 21 is operated preferentially to supply power to the secondary drive circuit 25, but when there is a power outage with the commercial AC power supply 1, the DC-side RCC type switching circuit 69 is operated to supply power to the secondary drive circuit 25, and these two switching circuits can be switched at high speed.Type: GrantFiled: October 6, 2000Date of Patent: January 7, 2003Assignee: Nihon Protector Co., Ltd.Inventor: Hiromi Matsushita
