Title: Starting device for stabilized power supply circuit
Inventor: NABETA EIICHI
IPC: G05F1/10
Filed: 1990-02-15
Abstract: PURPOSE:To prevent a failure of the rise of the output voltage at the time of power-on by giving the control output of a differential amplifier to the base of an auxiliary transistor TR after the rise of the voltage between both ends of a load at the time of supplying a DC power. CONSTITUTION:A bidirectional conduction type semiconductor switch which is turned on after the rise of a voltage E2 between both ends of the load consists of an auxiliary TR T3 and a diode D1 and is inserted between the base of an auxiliary TR T2 and the control output terminal of a differential amplifier Q1. That is, all of the current passing a starting resistance R1 flows to the base of the auxiliary TR T2 at the time of power-on to surely turn on the auxiliary TR T2 and a main TR T1. Thus, the anti-parallel circuit of the TR T3 and the diode D1 is can be made conductive in two ways to perform the constant voltage control.

Title: Constant voltage-generating circuit
Inventor: IDE AKIRA
IPC: H01L21/822
Filed: 1986-02-21
Abstract: PURPOSE:To obtain a stable reference voltage which is not dependent upon a source voltage by a method wherein, while a constant current is applied to a variable impedance device, the DC impedance of the variable impedance device is controlled by vary by the source voltage and the reference voltage is taken out from both terminals of the variable impedance device. CONSTITUTION:For instance, if the value of a constant current I applied to a variable impedance device Rx is increased following the increase of a source voltage VCC, the DC impedance of the variable impedance device Rx is reduced by the increase of the source voltage VCC. Therefore, by controlling resistance ratio of R1 and R2 and so forth to regulate the differential DELTAVCC of the source voltage VCC which is applied to the variable impedance device Rx as a control signal, increase and decrease of a reference voltage Vout taken out from both terminals of the variable impedance device Rx cancel each other so that the reference voltage Vout can be stabilized regardless to the fluctuation of the source voltage VCC. With this constitution, the constant reference voltage Vout which is not dependent upon the source voltage VCC can be obtained.

Abstract: PURPOSE:To prevent a CD storage tray from jutting out of a magazine or shaking even if vibration or shock is applied by arranging an elastic tray stopper so as to be opposite to the side surface of the tray send-out side of the magazine. CONSTITUTION:The tray stoppers 721, 722 positioned at the neighborhood of the tray send-out port of the magazine 100 are projected from the upper part and the lower part of a supporting frame 700, and an opening a little larger than one sheet of the CD storage tray 101 is formed between the stoppers 721 and 722, and it makes a tray conveying line where the CD storage tray 101 passes through. The stoppers 721, 722 are made into one body by cutting and raising the metallic supporting frame 700, and since they have elasticity, they are in contact with the CD take-out port of the magazine 100 from the bottom by elastic force. Accordingly, they push the CD storage tray 101 upward, and hold it at a normal position in the inside of the magazine 100. Thus, the CD storage tray 101 is prevented from being caught in the inside of the magazine 100 or shaking or falling into a state that it can not be taken out.
