Patent number: 8624408Abstract: In a circuit device of the present invention, the lower surface side of a circuit board and part of side surfaces thereof are covered with a second resin encapsulant, and the upper surface side and the like of the circuit board are covered with a first resin encapsulant. Since heat dissipation to the outside of the circuit device is achieved mainly through the second resin encapsulant, a particle size of filler contained in the second resin encapsulant is made larger than a particle size of filler contained in the first resin encapsulant. Heat dissipation to the outside of the circuit device is greatly improved.Type: GrantFiled: July 22, 2011Date of Patent: January 7, 2014Assignee: ON Semiconductor Trading, Ltd.Inventors: Katsuyoshi Mino, Masaru Kanakubo, Akira Iwabuchi, Masami Motegi

Patent number: 8481367Abstract: Provided is a method of manufacturing a circuit device in which a circuit element is resin-sealed with sealing resins formed integrally with each other. In the present invention, a resin sheet and a circuit board are housed in a cavity of a mold, and thereafter a first sealing resin formed of a tablet in melted form is injected into the cavity. At the time of injecting the first sealing resin, a second sealing resin formed of the resin sheet in melted form is not yet cured and is maintained in liquid form. Accordingly, the injected first sealing resin and the second sealing resin are mixed at the boundary therebetween, preventing the generation of a gap in the boundary portion and therefore preventing the deterioration of the moisture resistance and withstand voltage at the boundary portion.Type: GrantFiled: July 22, 2011Date of Patent: July 9, 2013Assignee: ON Semiconductor Trading, Ltd.Inventors: Katsuyoshi Mino, Akira Iwabuchi, Ko Nishimura

Patent number: 8305867Abstract: A lens including: a lens body having first and second surfaces; a flange part formed to protrude from a periphery of the lens body and to have a cylindrical outer circumferential surface; a lens installation surface formed at an outer edge part of the flange part; a recessed part formed as a part of the flange part such that a part of the cylindrical outer circumferential surface is recessed toward the optical axis; and a gate root part located at a central part of the recessed part. The gate root part has a flat surface which is in a same level with respect to the lens installation surface. The gate root part lies on an optical axis side with respect to a virtual curved surface formed by extending the cylindrical outer circumferential surface through the recessed part.Type: GrantFiled: June 3, 2011Date of Patent: November 6, 2012Assignee: Hoya CorporationInventors: Shungo Hanashiro, Akira Iwabuchi
