Title: Motor-driving circuit
Inventor: UZUKA MITSUO
IPC: H02P6/08
Filed: 1979-03-24
Abstract: PURPOSE: To change the rotating direction simply by a command signal, by providing a rotating-direction-changing device comprising npn and pnp transistors in a current switching-control circuit for a stator winding using the sensing signal of a rotor position.  
     CONSTITUTION: A signal which senses the rotor position is supplied from a light- emitting diode 1 and a shutter 2 to an emitter-follower circuit comprising transistors T 1 , T 2  and a resistor. From the emitter follower, is obtained a current-switching signal a which alternately becomes high and low at every 180° of electrical angle. During the period a motor is rotating in a forward direction, the high-level signal is supplied to a terminal 3, and a transistor T 11  is cut off without regard to the switching signal a. Therefore, a transistor T 10  is turned on and off depending on the current-switching signal, a transistor T 4  is turned on and off depending on the reversely phased signal of the collector of the TrT 10 , and the transistor T 3  is turned  on and off depending on the signal a of the emitter. Thus, coils LA and LB are alternately conducted at every 180°, and the motor is run in the forward direction. The motor is run in the reverse direction by supplying the low-level signal to the terminal 3.

Abstract: PURPOSE:To simplify the input operations of an operator by giving a prescribed correction to a correction object retrieved in response to a designated correcting function in accordance with sequence information on the set standard of the correction. CONSTITUTION:When an instruction is produced for start of a correcting function via an operator designating means 2, the means 2 gives a mode to a retrieving means 4 to retrieve the sequence information to be corrected out of document information stored in a document memory. Then an operator sets the standard sequence information for correction via a setting means 3 and this means 3 gives the set standard of correction to a correction means 5. The means 4 starts to retrieve the sequence information to be corrected out of a document memory 1 and gives successively the retrieved information to the means 5. The means 5 applies the prescribed correction to the retrieved correction object in accordance with the standard of correction. Thus it is possible to correct the sequence information in an extremely simple operation and with high accuracy.
