Title: Optical switch
Inventor: KAKO RYOJI
IPC: G02B26/08
Filed: 2002-11-01
Abstract: <P>PROBLEM TO BE SOLVED: To relax the allowable tolerance in manufacturing micro mirrors, to increase the yield and to reduce the cost.  <P>SOLUTION: In an optical switch, the optical path of an incident light beam is switched by forming a micro mirror 41 in an upright form on a movable electrode plate 11 arranged opposite to a fixed electrode plate 15, and the micro mirror 41 is moved by electrostatically driving the movable electrode plate 11 in the direction perpendicular to the plate face. The micro mirror 41 is provided with two reflection faces 42 and 43 which emit the incident light beam in an emitting direction which has a predetermined angle with respect to the incident direction by reflecting the incident light beam twice. Even when the micro mirror is manufactured by being rotated from a normal angular position, only a slight offset is generated because the direction of the emitted light beam does not deviate as much as twice the angle, which situation happens in a conventional rectangular solid type micro mirror.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide an opening and closing valve for a fuel cell of simple constitution that is automatically opened/closed to follow disconnection/connection of a main passage in a fluid feed line.  <P>SOLUTION: In an inner wall of a lower end surface of a body 14 composing this opening and closing valve for a fuel cell 10, a fluid inlet 44 having a valve seat 46 is provided. When pressure of compression air reaching the fluid inlet 44 becomes over total of pilot pressure in a second chamber 40 and resiliency energization force from a coil spring 82, a valve element 48 is pushed by the compression air to move up. Finally, a seat member 58 in a circular groove 56 provided in a lower end surface of a disc part 50 in the valve element 48 gets separated from the valve seat 46. As a result, the compression air passes from the fluid inlet 44 through a first chamber 38 to be discharged out of a second feed pipe 22. Air is thus fed through inside the opening and closing valve 10 for a fuel cell.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
