Patent number: 6928851Abstract: A riveting apparatus has a support die with a support surface. The support surface supports a rivet that extends through a circuit board and an electrical connector. The support surface has a first inclined surface, a second inclined surface, and a depression positioned therebetween. The depression receives a head of the rivet and positionally aligns the rivet with an upper tool unit as the rivet is guided across the first inclined surface toward the second inclined surface. The upper tool unit fastens the rivet to the circuit board.Type: GrantFiled: December 20, 2002Date of Patent: August 16, 2005Assignee: Tyco Electronics AMP K.K.Inventor: Hiroshi Yagawa

Patent number: 6546618Abstract: A rivet coupling device 1 has a connector holder unit 250 which carries connectors 200 and a board 50. A supporting die 150 is disposed beneath the connectors 200, and an upper tool unit 92 is disposed above the connectors 200. The upper tool unit 92 can be lowered in order to couple rivets 220. In conjunction with this movement, a link mechanism 30 is actuated to move a cam plate 80, whereby the supporting die 150 is raised slightly by cam projections 148, so that the rivets 220 extending through the connector 200 are deformed between crimpers 134 on the upper tool unit 92 and the supporting die 150. Prior to rivet coupling, a slight gap is formed by the spring terminals between the board 50 and the connector 200. After rivet coupling is performed, this gap is eliminated without deforming the board 50.Type: GrantFiled: May 23, 2000Date of Patent: April 15, 2003Assignee: Tyco Electronics AMP K.K.Inventor: Hiroshi Yagawa

Patent number: 6316343Abstract: A method of manufacturing a transparent conductive film is provided, which is capable of obtaining a transparent conductive film having both reduced specific resistance and reduced film compressive stress, and a transparent conductive film manufactured by the same method is also provided. The temperature of a substrate placed in opposed relation to an anode is set to not more than 130° C. A plasma beam is generated by discharge plasma generating means constituting a cathode and guided to the anode such that an evaporation material received in the anode evaporates and particles of the evaporated materials are ionized, to thereby form the transparent conductive film on a surface of the substrate. The transparent conductive film thus formed is subjected to a heat treatment at a temperature of not less than 180° C. The resulting transparent conductive film has a specific resistivity of 230 &mgr;&OHgr;·cm or less and a film compressive stress of 0.35 GPa or less.Type: GrantFiled: March 29, 2000Date of Patent: November 13, 2001Assignees: Nippon Sheet Glass Co., Ltd., Sumitomo Heavy Industries, Ltd.Inventors: Syunji Wada, Hiroshi Yagawa, Motohisa Mineo, Yuichi Aoki, Ryoji Chikugo, Akihiko Yoshii

Patent number: 5343617Abstract: Simultaneous attaching of wires (13) through the pressure-connecting method to a number of electrical connectors (11) arranged in a row, makes it possible to process a larger number of electrical connectors at one time. A position-determining device (55) is provided for each electrical connector (11) which makes it possible to determine the position of each pressure-type contact of said electrical connectors (11) arranged in a row. The positioning determining device (55) is used to align a plurality of the electrical connectors (11) so that tolerance differences are not cumulative. FIG. 12.Type: GrantFiled: March 19, 1993Date of Patent: September 6, 1994Assignee: The Whitaker CorporationInventors: Hiromi Tanaka, Hiroshi Yagawa

Patent number: 5269206Abstract: An apparatus (11) for stripping cable (12) to remove a section of cable jacket (13) includes opposed stripping blades (15) each having a pair of adjacent blade sections (18) including semi-circular cutting edges (19) defined by grooves (20) operable to cut the jacket (13) peripherally with the adjacent blade sections (18) driven axially apart in a relative sense to pull the cut section of the jacket away from the cable. Pairs of guide and gripping members (16) having internesting teeth (23, 24) are positioned adjacent the blade sections (18) to grip the cable (12) and provide a support for the cable. A suction device (17) is displaced axially to receive the cut jacket section and remove such from the stripping site.Type: GrantFiled: December 2, 1992Date of Patent: December 14, 1993Assignee: AMP IncorporatedInventor: Hiroshi Yagawa
