Publication number: 20130108785Abstract: A powder coating method is capable of forming a coating film having excellent adhesion and surface texture by using a thermosetting powder coating material. The powder coating method is configured to include: a heating step of heating a spring member; a coating step of causing a thermosetting powder coating material to adhere to a surface of the spring member, with a surface temperature T (° C.) of the spring member being in a range of “Tf?20?T<Tf+20” (Tf: a curing completion temperature (° C.) of the thermosetting powder coating material), and a curing step of curing the thermosetting powder coating material adhering to the surface of the spring member. In the curing step, the surface temperature T (° C.) of the spring member upon completion of the curing is desirably “Ts+30?T” (Ts: a curing start temperature (° C.) of the thermosetting powder coating material).Type: ApplicationFiled: April 1, 2011Publication date: May 2, 2013Applicant: CHUO HATSUJO KABUSHIKI KAISHAInventors: Takayuki Okamoto, Yasuhiko Kunita, Masami Wakita

Patent number: 8157545Abstract: A hermetic compressor includes a hermetic container arranged to store lubricating oil, a motor element accommodated in the hermetic container, an oil-feeding mechanism arranged to carry the lubricating oil, and a centrifugal pump arranged to carry the lubricating oil to the oil-feeding mechanism. The centrifugal pump includes a cylindrical portion having a hollow opening at the opening, and an aperture plate having a suction aperture formed therein. The aperture plate has an inner edge facing the suction aperture, and an outer edge of the aperture plate contacting an inner surface of the cylindrical portion. A portion of the aperture plate between the inner edge and the outer edge of the aperture plate is positioned more outward from the cylindrical portion than the inner edge and the outer edge are. This hermetic compressor does not produce fine metal powder during manufactured, having high reliability.Type: GrantFiled: October 27, 2008Date of Patent: April 17, 2012Assignee: Panasonic CorporationInventor: Takayuki Okamoto

Publication number: 20110262153Abstract: At least one of processing units is capable of being pulled out of a main body of an apparatus during the occurrence of a sheet conveyance jam. A first cutter and a second cutter are arranged in the vicinity of the processing unit. The first cutter is configured to cut the sheet on an upstream of the processing unit. The second cutter is configured to cut the sheet on a downstream thereof. When the processing unit is pulled, the sheet is cut on the upstream and downstream of the processing unit.Type: ApplicationFiled: December 7, 2010Publication date: October 27, 2011Applicant: CANON KABUSHIKI KAISHAInventors: Kanto Kurasawa, Yoshiaki Suzuki, Toshiaki Tokisawa, Masahito Yoshida, Kota Uchida, Takayuki Okamoto

Publication number: 20110211007Abstract: In the event that occurrence of a jam has been detected during conveyance of a sheet, the sheet is cut at a cutter unit, and a user is prompted to perform manual jam restoration processing according to the location where the jam has occurred. If the jam has occurred upstream from the cutter unit, the cut sheets left downstream from the cutter unit are discharged as completed articles.Type: ApplicationFiled: November 30, 2010Publication date: September 1, 2011Applicant: CANON KABUSHIKI KAISHAInventors: Takayuki Okamoto, Masahito Yoshida, Kota Uchida
