Title: Speed detector in vector controller for induction motor
Inventor: ASHIKAGA TADASHI
IPC: H02P21/00
Filed: 1986-12-04
Abstract: PURPOSE:To improve unevenness in extremely low speed rotation by reducing speed detection ripple generated by sampling errors and the like by filter calculation only in the extremely low speed rotation. CONSTITUTION:Frequency signals corresponding to the rotational speed of a motor are led out and the rotational speed is calculated on the basis of the count and the period of reference clocks corresponding to the unit period of the frequency signals. At this time, filter calculation is effected on the rotational speed under the condition that the rotational speed is lower than an arbitrarily set filter calculation speed. Detection ripple is reduced by delaying speed detection at a speed below the arbitrarily set one. Thus, the motor can be operated in stable condition wherein there is no unevenness in rotation even in extremely low speed.

Title: Method for setting initial test force in press type hardness tester
Inventor: ODA MITSURU
IPC: G01N3/44
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To make a load of an initial test force highly accurate at a Rockwell hardness test. SOLUTION: A sample stage 22 is raised by rotating a sample stage motor 26 forward until a load slightly smaller than a predetermined initial test force is applied by an indenter 15 to a sample T. After the motor 26 is stopped, a motor 30 is driven to press the indenter 15 to the sample T via a load lever 11. The initial test force is set accordingly. At this time, a press force of the indenter 15 detected by a load sensor 50 is fed back to a control part 60 for the motor 30, so that the initial test force can be set highly accurately.
