Title: Rotor of superconductive rotary electric machine
Inventor: UEDA AKINORI
IPC: H02K3/46
Filed: 1984-07-05
Abstract: PURPOSE:To effectively rigidly hold a superconductive field coil by disposing a retainer on a supporting member to press a wedge for holding the coil, thereby securing to a coil mounting shaft. CONSTITUTION:A supporting member 23 is disposed adjacent to the corner of a superconductive field coil 3 in a stepped slot 18, and secured by a bolt 24 to a coil mounting shaft 2. Then, a retainer 25 is disposed on the member 23, clamped by a bolt 25 to the member 23, and a wedge 27 is pressed radially inward, thereby holding the arc portion and the corner of the coil 3 rigidly. Thus, since the member 23 and the retainer 25 are not moved, it can prevent the coil 3 from moving during operation.

IPC: F04D29/36
Filed: 1979-11-02
Abstract: PURPOSE: To provide the rotor blade controlling system for the rotor blade control  type axial-flow fan, which is provided with a dead time generating means in its hydraulic circuit for operating the rotor blades, so that it may not respond to  short-period fluctuation of air amount but it is operated to move the blades in case that fluctuation in the air amount, having periods longer than a predetermined time length, is caused in controlling the amount of air to be supplied to a thermal power  plant or the like.  
     CONSTITUTION: An actually measured air amount (q) at the time is compared with an instructed air amount Q in a controller 17 and the output signal of the controller 17 is given to an actuator 13. Here, if fluctuation is caused in the actually measured air amount (q) and resultantly an arm of actuator 13 is moved vertically at short periods although the average air amount indicates correctly the instructed air amount Q, it only causes lateral movement of a piston 22 of a dead time generating means 20. Therefore, it is prevented that hydraulic pressure is acted to a control cylinder 6.
