Title: Constant voltage circuit
Inventor: YOSHIHISA KOUZOU
IPC: G05F1/56
Filed: 1978-09-21
Abstract: PURPOSE: To avoid the malfunction with satisfaction of the base bias conditions although the elements have some dispersion by increasing the emitter area of the transistor constituting the starting circuit and thus using VBE in a small amount.  
     CONSTITUTION: As output transistor Q 11  is not turned on at the starting time, no bias is applied to the base of Q 7  and thus with no ON given to Q 7 . However, the current flows to the starting circuit via resistance R 1 , and as a result the bias is applied to the base of Q 6  constituting the differential switching circuit. Thus Q 6  is turned on. As a result, Q 4  and Q 5  forming the current Miller circuit are turned on to accordingly turn on Q 11 , and thus the reference voltage is generated at output terminal V 0 . The reference voltage is applied in the form of the base bias of Q 7  owing to the 1st bias circuit consisting of R 5  and R 6 . And Q 6  is turned off as soon as Q 7  is turned on. So that Q 10  is turned on to control Q 11 , thus obtaining the steady reference voltage at V 0 .

Title: Motor control unit of tape recorder
Inventor: KUSUDA TOORU
IPC: G11B15/48
Filed: 1979-09-10
Abstract: PURPOSE: To reduce and remove shocking load and unstable running of a tape, by making the capstan motor respond with the time constant to the speed change operation.  
     CONSTITUTION: When the switch 28 is set to the contact 29 in a state that the contact 27 of the variable resistor VR is moved suddenly or it is located at the left end of the resistor VR or its vicinity, in order to change the running speed of a tape, that is, the rotary speed of the capstan motor 11, the potential of the + input terminal 25 is also apt to follow. In this case, since a capacitor C 4  is provided, the potential of the terminal 25 does not reach the value decided by the resistor VR and resistors R 5 , R 6  immediately, but it is varied with the time constant. Accordingly, the rotary speed of the motor 11 is not changed suddenly but it is increased or decreased gradually. Thus, it is possible to reduce and remove shocking load by the capstan and the pinch roller, and also unstable running.
