Patent number: 9033680Abstract: An electric fan is provided, including a labyrinth structure with increased performance of preventing entry of a liquid into a receiving space to receive a stator and a rotor. A clearance is defined between an opposed wall portion of a base and an opposed wall portion of an impeller body, which are opposed to each other in an axial direction of a rotary shaft, to form a labyrinth structure. The opposed wall portion of the base and the opposed wall portions of the impeller body are shaped to form a volume expanding portion within the clearance. The volume expanding portion is constituted from a groove portion for expanding the clearance, having a volume larger than other portions within the clearance.Type: GrantFiled: March 21, 2014Date of Patent: May 19, 2015Assignee: SANYO DENKI CO., LTD.Inventors: Naruhiko Kudo, Tomoaki Ikeda, Haruhisa Maruyama

Patent number: 8164008Abstract: A cable is sandwiched between a first inner wall surface of a peripheral-wall-side pressing wall portion and a first inner wall surface of a cap-side pressing wall portion, between a second inner wall surface of the peripheral-wall-side pressing wall portion and a second wall surface of the cap-side pressing wall portion, and between a third inner wall surface of the peripheral-wall-side pressing wall portion and a third inner wall surface of the cap-side pressing wall portion to crank the cable to form a cranked portion of the cable. The peripheral-all-side pressing wall portion and the cap-side pressing wall portion sandwich the cranked portion therebetween. Thus, defective soldering may be prevented between a plurality of lead wires and a core-wire soldered portion to which core wires of the lead wires are soldered and connected.Type: GrantFiled: February 23, 2010Date of Patent: April 24, 2012Assignee: Sanyo Denki Co., Ltd.Inventors: Haruhisa Maruyama, Tomoaki Ikeda, Takahisa Toda

Patent number: 7742302Abstract: An axial-flow fan unit that produces less noise is provided. Blades 19 are exposed from a venturi 29. The shape of each of the blades 19 is so defined that a space formed between at least an inner surface 28a of each of web leg sections 28A to 28C and an edge 19a of each of the blades 19 located in the radially outward direction of the blades 19 expands toward the ends of the web leg sections 28A to 28C (or web bodies 30A to 30C). With this arrangement, noise produced when the blades 19 rotate along the web leg sections 28A to 28C is reduced.Type: GrantFiled: January 16, 2008Date of Patent: June 22, 2010Assignee: Sanyo Denki Co., Ltd.Inventors: Michinori Watanabe, Toshiki Ogawara, Haruhisa Maruyama

Publication number: 20090218079Abstract: There is provided a heat-emitting element cooling apparatus capable of enhancing cooling effect on a heat-emitting element as well as reducing noise. A heat sink includes a core portion and a plurality of radiation fins fixed to the core portion. Dimensions of the core portion and the radiation fins are defined in such a manner that the diameter L1 of the core portion should be 37% to 45% of the diameter L2 of a shape depicted by a virtual connecting line which connects end portions of the radiation fins.Type: ApplicationFiled: February 26, 2009Publication date: September 3, 2009Applicant: SANYO DENKI CO., LTD.Inventors: Michinori Watanabe, Haruhisa Maruyama, Toshiki Ogawara, Koji Ueno

Patent number: 7411327Abstract: There is provided a fan unit in which when the fan unit is conveyed, existence of a plurality of lead wires will not become an obstacle to the conveyance. Four lead wire engaging sections 27, 29, 31, and 33 are provided along the contour of an outer wall section 25 of a fan casing 15 as the fan casing 15 is viewed from a predetermined position in a forward direction. Then, the lead wire engaging sections 27, 29, 31 and 33 are configured to engage a part of lead wires 24 so as to prevent the lead wires 24 from coming out of the fan casing 15 one or more during the conveyance.Type: GrantFiled: May 12, 2005Date of Patent: August 12, 2008Assignee: Sanyo Denki Co., Ltd.Inventors: Michinori Watanabe, Toshiki Ogawara, Haruhisa Maruyama

Patent number: 7391691Abstract: In one embodiment, a disc has a substrate; a data layer on the substrate; an anomaly-feature in the data layer disc capable of generating a read anomaly having a predictable anomaly profile; and anomaly profile data recorded in the data layer for characterizing the anomaly-feature. A disc can be labeled by imposing an anomaly-feature in the data layer capable of generating a read anomaly having a predictable anomaly profile; and disposing anomaly profile data on the disc, wherein the anomaly profile data characterizes the anomaly-feature.Type: GrantFiled: August 24, 2004Date of Patent: June 24, 2008Assignee: General Electric CompanyInventors: Haruhisa Maruyama, Matthew F.
