Publication number: 20150222036Abstract: A connector pair comprises a first connector and a second connector which are mateable with each other. The first connector includes a first contact having a first contact portion which has a first plating layer made of silver or silver alloy. The second connector includes a second contact having a second contact portion which has a second plating layer made of silver or silver alloy. The second contact portion has a contact start point and a final contact point. The second plating layer has Vickers hardness not less than 120 Hv but not more than 180 Hv. The Vickers hardness of the second plating layer is larger than Vickers hardness of the first plating layer. When the first connector and the second connector are mated with each other, the first contact portion slides on the second contact portion from the contact start point to the final contact point.Type: ApplicationFiled: November 14, 2014Publication date: August 6, 2015Applicant: JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Kazuomi SATO, Sae TSUGAWA

Publication number: 20150170976Abstract: The present invention provides technology for realizing higher purification of a polycrystalline silicon. First, trichlorosilane is prepared as a sample (S101) and then the carbon-containing impurities content in the trichlorosilane is analyzed by GC/MS-SIM method (S102). The quality of the trichlorosilane is determined based on the analysis results (S103) and the trichlorosilane determined to be a good material (S103: Yes) is used as the raw material for producing a high-purity polycrystalline silicon by CVD method (104). In case, the trichlorosilane determined to be a bad material (S103: No) is not used as the raw material for producing a polycrystalline silicon. When the impurities analysis by GC/MS-SIM method is performed using, as a separation column, a column having a non-polar column and a medium-polar column connected in series with each other, it is possible to simultaneously perform both of the separation of chlorosilanes and hydrocarbons and the separation of chlorosilanes and methylsilanes.Type: ApplicationFiled: June 13, 2013Publication date: June 18, 2015Applicant: Shin-Etsu Chemical Co., Ltd.Inventors: Kazunori Funazaki, Kazuomi Sato, Shuichi Miyao

Patent number: 7267573Abstract: Having conductive contacts (4), a first insulator (1) retaining the contacts, and a cable-side insulator, attachable/detachable relative to the first insulator, for retaining a flat cable (6). The cable-side insulator includes a second insulator (2) for receiving the flat cable, a third insulator (3) disposed so as to confront the second insulator via the flat cable, and a clamp (7) interposed between the flat cable and the third insulator. When the cable-side insulator is mounted to the first insulator, the second and third insulators are engaged with the first insulator to approach each other so that the flat cable is sandwiched between the clamp and the second insulator. In this state, the flat cable is connected to the contacts.Type: GrantFiled: July 6, 2006Date of Patent: September 11, 2007Assignees: Japan Aviation Electronics Industry, Limited, NEC CorporationInventors: Kazuomi Sato, Masahiro Yamauchi
