Abstract: PURPOSE: To make the constitution of a two-dimensional vibration testing machine simple by connecting a vibration table and a vibrating cylinder by way of plural static pressure shaft couplings and a movable shaft perpendicular to a piston rod thereby receiving rotation moment.  
     CONSTITUTION: With a cylinder 3 which drives a piston rod 4 as a vibrating source, a vibrating table 1 vibrates in one direction and at the same time rotation moment is generated. This moment is received by a movable shaft 16a perpendicular to the piston rod 15 which is driven by a cylinder 14 supported by static pressure bearings 16b, 16c. Hence, the vibrating table 1 is vibrated in the direction at a right angle to the vibrations by the cylinder 4 without being unaffected by the moment by way of one set of the cylinders 14, whereby two-dimensional vibration testing is accomplished. As a result, the need for receiving the moment by synchronously driving plural cylinders is eliminated and the constitution of the two-dimensional vibration testing machine may be simplified.

Title: Device for synchronous input of synchronous motor
Inventor: GOTOU MASUO
IPC: H02P1/52
Filed: 1978-02-15
Abstract: PURPOSE: To reduce a shock in parallel input by the means such that the loss of torque of motor is measured, a lag of phase of the motor is predicted according to a delay time from input cutoff to synchronous input, and the synchronous input is performed at the point the above prediction is estimated.  
     CONSTITUTION: When the dynamotor 1 of the pumping-up power plant is started by the thyristor starter 8-10 as a sychronous motor, the input current required to maintain the rated speed is measured by the power detector 20, the phase shift of motor from input cutoff to synchronous input is calculated by the phase-shift detector 21, and it is fed to the synchronization detector/speed equlizer 19 to control APPS 13, 14. Since the speed-change and phase-shift of the motor are proportinal to the input current in synchronous input, a smooth parallel input can be done by making the speed higher than the rated value and by detecting the synchronization on leading the phase by the synchronization detector/speed equalizer 19.
