Publication number: 20140138023Abstract: A plurality of thermoplastic articles are superimposed against a support, an infrared transparent solid is superimposed to form a superimposed body and infrared is irradiated to the superimposed body from the side of the infrared transparent solid. For the irradiation source, an Er: YAG laser or fiber laser is used. The interface temperature of the thermoplastic article becomes relatively lower and a high temperature region can be developed within the superimposed body due to the infiltration of laser energy. As a result, degradation of the surface configuration due to thermal damages in the infrared irradiation side surface layer of the thermoplastic articles can be suppressed.Type: ApplicationFiled: January 24, 2014Publication date: May 22, 2014Applicant: Campus Create Co., Ltd.Inventors: Yasuo Kurosaki, Kimitoshi Satoh

Publication number: 20110288800Abstract: The present invention provides a novel measurement method for system parameters of a 5-port junction used in a VNA (Vector Network Analyzer). A VNA is a device for measuring amplitude ratios and phase differences (S-parameters: scattering matrix elements) between incident waves and reflected waves of a DUT (Device Under Test), or between input waves and transmitted waves. What has been newly discovered is that for 5 ports, S-parameters can be expressed by a linear coupling using H and power difference ratios ({P(S)/P(0)}?1). It is possible to easily calculate parameter H using a minimum of three already known standards, and amount of calculation can be reduced compared to conventionally.Type: ApplicationFiled: February 2, 2010Publication date: November 24, 2011Applicants: CAMPUS CREATE CO., LTD., THE UNIVERSITY OF ELECTRO-COMMUNICATIONSInventors: Hajime Kondo, Toshiyuki Yakabe, Hatsuo Yabe

Patent number: 7879412Abstract: A diamond thin film coating method is provided that enables, with no need for an intermediate layer, the formation of a diamond thin film, which has conventionally been considered difficult because cobalt contained in a binding phase of a cemented carbide provides a catalysis for the formation of graphite. Cobalt in a binding phase (11) present in a surface of a cemented carbide substrate member comprised of a hard phase of a carbide (2) and a binding phase (1) containing cobalt, is silicidated into silicide (3), and thereafter the diamond thin film is formed.Type: GrantFiled: June 10, 2005Date of Patent: February 1, 2011Assignees: The University of Electro-Communications, Campus Create Co., Ltd.Inventor: Hideo Isshiki

Publication number: 20100099534Abstract: The present invention provides a transmission unit that can realize a high speed-shifting ratio, can realize reduced size, low cost and low noise, and is also capable of limiting slip loss. Outer peripheral surfaces of a small diameter rolling element and a supplementary rolling element are brought into contact with an outer peripheral surface of a large diameter rolling element. The supplementary rolling element is arranged at an almost opposite side to the small diameter rolling element, thus enclosing the large diameter rolling element between the small diameter rolling element and the supplementary rolling element. An inner peripheral surface of the pressure adjustment ring is brought into contact with the outer peripheral surface of the small diameter rolling element and the outer peripheral surface of the supplementary rolling element, and is supported by them.Type: ApplicationFiled: November 13, 2007Publication date: April 22, 2010Applicants: SHONAN INSTITUTE OF TECHNOLOGY, CAMPUS CREATE CO., LTD.Inventors: Masayoshi Muraki, Kikuo Okamura
