Title: Regenerative power absorber
Inventor: TAGAMI YOSHIHIRO
IPC: B60M3/06
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To control absorption power continuously by providing a load distributing unit for determining load distribution to each of a plurality of unit choppers so as to adjust absorption power by the unit choppers. SOLUTION: Individual conduction ratios every unit chopper are generated by limiters 341 -343 , coefficient multipliers 344 -346 and adders 347 , 348 in a load distributing unit 34 from a conduction ratio δ to a regenerative power absorber 3. On the basis of these conduction ratios, PWM driving signals every unit chopper are generated by a chopper driving circuit 35 to control each unit chopper. In the regenerative power absorber 3, a conduction ratio uncontrollable range is only a range less than 0.1/3 and a range exceeding 2.9/3, and the conduction ratio uncontrollable range is reduced to 1/3 respectively on both lower limit side and upper limit side. Since the substantial conduction ratio uncontrollable range is thus reduced by a large margin, a control range of electric overhead line voltage is enlarged, and stabler electric overhead line voltage can be realized.

Filed: 1990-09-27
Abstract: PURPOSE:To conduct a stable excitation for preventing a superconductive wire rod from quenching, even if an electromagnetic force acts on the wire rod, by winding the binder of a member larger in heat shrinkage rate than the superconductive wire rod on the outer peripheral side of a superconductive coil and by using as a spool a member smaller in the heat shrinkage rate than the superconductive wire rod to suppress the minute movement of the superconductive wire rod.

Title: Position detector
Inventor: YAMANAMI TSUGUNARI
IPC: G06F3/046
Filed: 1986-10-27
Abstract: PURPOSE:To attain the simultaneous use of plural indicators by receiving a radio wave from a position indicator generated from each coil of a position detection section through the sending of the radio wave so as to detect a designated position of the position indicator, while offering excellent operability and high accuracy. CONSTITUTION:The loop coil 11-1 of a position detection section 1 is selected by a selection circuit 2 and connected to a transmission circuit 6 by a connection switch circuit 3, then the radio wave of a prescribed frequency is generated. A tuning inductive radio wave is generated at the tuning circuits 41, 45 of position indicators 4, 5 by the radio wave. When the circuit 3 switches the coil 11-1 to the position of a reception circuit 7, the radio wave is lost. The radio wave from indicators 4, 5 is received by the circuit 7, the coil 11-1 is excited in opposite polarity and induced voltages of the same frequency but different phase are combined and generated. The transmission/ reception of the radio wave is executed sequentially by switching all loop coils, as the distance between the loop coil and each indicator is smaller, the induced voltage is increased and reaches a maximum value at a position placed with the indicator. The value of each induced voltage is detected at every phase difference by the circuit 7 and a designated coordinate is obtained by a processor unit 8.
