Title: Controller for induction motor
Inventor: SAKAMOTO KEIJI
IPC: H02P27/06
Filed: 1985-05-07
Abstract: PURPOSE:To suppress an unexpected noise and an iron loss increase without generating harmonic waves by reducing a torque command value in response to the excess of a terminal voltage when the terminal voltage exceeds the prescribed value. CONSTITUTION:Motor terminal voltage detecting means 6 detects the terminal voltage of an induction motor 3. Overvoltage detecting means 7 compares the detected voltage with a reference voltage such as the DC voltage of a PWM controller to detects that the terminal voltage of the motor 3 exceeds the reference voltage. Torque command reducing means 8 superposes a negative signal on the torque command signal in response to a voltage excess. Thus, when the terminal voltage becomes the prescribed value or higher, the torque command signal E decreases as compared with the normal case, the reduced torque command signal Ee is applied to a vector calculator 5, converted to a current command signal F, applied to a PWM controller 9, and the motor 3 is controlled on the basis of the command.

Abstract: PURPOSE: To automatically detect information on the position of a tape such as a ribbon in an ink ribbon cassette or the like, by moving a detection member, which is provided on the tape, to change the relative positions of the detection member and another one.  
     CONSTITUTION: The ink ribbon roll is rotatably supported on a shaft 6 in the ink ribbon cassette 2. The ribbon 1 pulled out of the roll is sequentially sent out by the cooperation of a drive roller 3 with a pinch roller 4. A loading spring 7 made of an electroconductive material is normally thrusted on the inside wall 2c of the cassette to prevent the ribbon from sagging. When the ribbon 1 is used to the vicinity of its end, an eyelet 1a provided near the end of the ribbon goes in between the inside wall 2c and the loading spring 7 to thrust the spring toward a switch 8 provided on a printing unit. As a result, the spring comes into contact with the electrodes 8a, 8b of the switch 8. The end of the ribbon is thus detected.
