Title: System and method for variable speed wind power generation
Inventor: ARINAGA SHINJI
IPC: F03D7/04
Filed: 2001-05-16
Abstract: PROBLEM TO BE SOLVED: To properly control revolution speed in order to obtain a maximum electric power. SOLUTION: This variable speed wind power generation system comprises: setting equipment 15, 16 for setting a windmill parameter corresponding to a wind velocity; a computing unit 22 for computing a generated energy of an induction generator 1; and a revolution speed control instruction calculator 8 for calculating a revolution speed control instruction based on the windmill parameter, the generated energy, and the revolution speed of the induction generator 1. The windmill parameter is constituted only of three functions of an output set value P(V), a revolution speed set value N(V), and a pitch angle set value θ(V) which are described by the wind velocity (V).  By defining values of the three control variables corresponding to the wind velocity, proper and efficient control of an output of the induction generator or the revolution speed corresponding to the output is performed. Based on a magnitude relation of the output set value P(V) and the revolution speed set value N(V) corresponding to a rated output PRAT and rated revolution speed NG of the induced generator 1, limiters 34, 38 are added which regulate a pitch angle instruction θSET with respect to the windmill 2 and an output instruction PSET with respect to the induced generator 1 so that the instructions are within respective set regions. An excessive increase of revolution speed is effectively and simply prevented by such a control logic.

Title: Key operation detector
Inventor: KIMURA MASAJI
IPC: G10C3/12
Filed: 2001-05-24
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing cost by decreasing the number of elements necessary for the constitution of a key action detector for detecting the action of keys. SOLUTION: A wippen 15 exists normally in a position shown by solid lines and when the key is pushed, the wippen successively passes a first oscillation position shown by an arrow A and a second oscillation position shown by an arrow B. The laser beam L emitted by a light emitting element 33 does not normally fall onto a metallic plate 31 but when the wippen 15 oscillates to the first oscillation position, the light is reflected by the surface of the metallic plate 31 and is received by a light receiving element S1. When the wippen 15 oscillates to the second oscillation position, the light is reflected by the surface of the metallic plate 31 and is received by a light receiving element S2. The key is judged to be pushed when the light receiving elements S1 and S2 successively receive the laser beam L.  The number of the light emitting elements necessary for the constitution of the device can therefore be decreased.
