Patent number: 7438598Abstract: The connector housing 30 is formed with a pair of guide grooves 50a, 50b and a pair of side walls 60. The guide grooves 50a, 50b support the both side edges of the upper body portion 21 of the thick first card 20 and also the both side edges of the card body 11 of the thin second card 10 and guide these cards as they are inserted or extracted. The side walls 60 define, below a space between the paired guide grooves 50a, 50b, a space in which to accommodate the lower body portion 23 of the first card 20. This construction ensures that, whichever of the first and second cards is inserted, the elastic displacements of the contact terminals 40 of a card connector 1 remain the same, allowing the card to be electrically connected stably.Type: GrantFiled: November 2, 2000Date of Patent: October 21, 2008Assignees: Yamaichi Electronics Co., Ltd., Matsushita Electric Industrial Co., Ltd.Inventors: Toshiyasu Ito, Masaaki Oya, Kazutaka Taguchi, Takashi Torii, Hideki Kawai

Patent number: 7228544Abstract: In the prior art, a user bore a heavy burden on operating together different products having the same functions. A user 102 calls a job net managing function 105 via GUI/CLI 103, and defines a job net 106. A job net execution controlling function 109 interrupts a definition of the job net 106, and sequentially executes the defined jobs. The defined jobs call not real commands directly, but switchers 110 to 114 that define regularized interfaces. The switchers, referring to environment variables 101, select adaptors 115 and 116 properly to call real commands 117 and 118 corresponding thereto.Type: GrantFiled: February 20, 2003Date of Patent: June 5, 2007Assignee: Hitachi, Ltd.Inventors: Masanori Honda, Takaki Kuroda, Masaaki Oya, Masao Menjo

Patent number: 6984353Abstract: A method for manufacturing a polyimide sleeve where a polyimide sleeve of a high quality can be manufactured easily with a superior yield. A sleeve of a release resin is fitted on a planished metal core or a core at least whose outer surface is made of a release resin, and a polyimide precursor solution is applied on its outer surface. Next, after generating an imide reaction of the polyimide precursor by heating to form an almost completely cured polyimide sleeve, this polyimide sleeve is removed from the core together with the sleeve of the release resin. Furthermore, the polyimide sleeve is separated from the sleeve of the release resin.Type: GrantFiled: June 3, 2002Date of Patent: January 10, 2006Assignee: Showa Electric Wire & Cable Co., Ltd.Inventors: Toshinobu Asai, Masaaki Oya, Takayuki Yamazaki

Patent number: 6729892Abstract: A card connector that reliably holds an inserted card with a compact mechanism to prevent the falling of the card due to unexpected external forces. The card 10 is formed with the recess 18 to receive the locking portion. The elastic locking piece 50 is mounted to the eject member 41 that slides together with the card 10 as the card is inserted or retracted. The locking piece guide means 50b, 61 converts the motion of the eject member 41 in the card insertion/retraction direction into the motion of the locking portion 50c of the elastic locking piece 50 toward or away from the card so that the locking portion 50c is engaged in the recess 18 during the card insertion and, during the card ejection, is disengaged from the recess 18.Type: GrantFiled: April 11, 2001Date of Patent: May 4, 2004Assignee: Yamaichi Electronics Co., Ltd.Inventors: Toshihumi Takada, Masaaki Oya, Minoru Igarashi
