Patent number: 8523603Abstract: A connector assembly includes a first connector and a second connector. The second connector is engageable with the first connector along a downward direction in a state where the first connector is below the second connector. The second connector includes a second contact, a second holding member and an operating portion. The operating portion is held by the second holding member so that a positional relation therebetween is kept when a force is applied to the operating portion along an upward direction and when a force is applied to the operating portion along a first horizontal direction perpendicular to the upward direction or a second horizontal direction opposite to the first horizontal direction. The second connector is removable from the first connector when a force is applied to the operating portion either along the upward direction or along the first or second horizontal direction.Type: GrantFiled: June 29, 2011Date of Patent: September 3, 2013Assignee: Japan Aviation Electronics Industry, LimitedInventors: Takahiro Yamaji, Akira Kimura, Kazushi Kamata, Shuichi Ishida, Tomomi Sakata

Patent number: 7189625Abstract: In a micromachine according to this invention, a polyimide film is formed on the surface of each electrode. The polyimide film is formed as follows. A substrate having each electrode and a counterelectrode are dipped in an electrodeposition polyimide solution, and a positive voltage is applied to the electrode. A material dissolved in the electrodeposition polyimide solution is deposited on a surface of the positive-voltage-applied electrode that is exposed in the solution, thus forming a polyimide film on the surface.Type: GrantFiled: October 4, 2005Date of Patent: March 13, 2007Assignee: Nippon Telegraph and Telephone CorporationInventors: Hiromu Ishii, Yasuyuki Tanabe, Katsuyuki Machida, Masami Urano, Shouji Yagi, Tomomi Sakata

Patent number: 6445845Abstract: An optical switch for switching a light path between two optical waveguides is provided. The switch has a slit formed diagonally cutting across the crossing point of crossing optical waveguides and a substance in the slit has a function of transmitting or reflecting an optical signal is selectively held in the slit. The slit is narrower than cores of the optical waveguides, and has a center line formed on a bisection of an interior angle between optical axes of the crossing optical waveguides. Thus, the substance in the slit serves to make optical intensity reflected to each of the optical waveguides uniform. Further, a crossing optical waveguide consists of a reflecting structure having its interior filled with air during reflection and the intersecting angle between the first group of optical waveguides is between 0 to 90 degrees and preferably substantially between 73 and 74 degrees.Type: GrantFiled: April 26, 2000Date of Patent: September 3, 2002Assignee: Nippon Telegraph and Telephone CorporationInventors: Tomomi Sakata, Hiroyoshi Togo, Fusao Shimokawa, Mitsuhiro Makihara
