Patent JP-H03128629-A (JP)
Title: Power supply system
Inventor: SUGA IKURO
IPC: H02H7/12
Filed: 1989-10-13
Abstract: PURPOSE:To prevent the heat generation of a primary iron core and a primary winding during separation of a transformer by stopping the switch operation of a switching element during separation of the transformer by the use of an ON/OFF changeover means not to let currents flow to the primary winding at the time of separation of the transformer. CONSTITUTION:When separating a transformer 7 with a separator 8, an ON/ OFF changeover circuit 15 interlocks, and a control circuit 6 stops the switching operation of a switching element 5. Hereby, the delivery of energy from an AC/DC converter 4 is stopped, and the currents are made not to flow to a primary winding and the switching element 5. Moreover, when coupling the transformer 7, the ON-OFF changeover circuit 15 operates after the coupling is completed, and the control circuit 6 starts the switching operation of the switching element 5, and supplies power to load.

Filed: 1989-10-13
Abstract: PURPOSE:To stabilize an FET driving circuit and to prolong the life of an FET caused by radiation degradation by impressing inverse bias between the gate and source of the FET in a switching power source under a radiation irradiation environment. CONSTITUTION:An inverse bias circuit 7 is provided between the collector of a second transistor 4 for FET driving and the source of au FET transistor 5 and composed of the parallel circuit of a serial diode and a capacitor. A direct current power source 1 is connected between the collectors of first transistor 3 for driving and second transistor 4 for driving and connected to a frequency oscillator 2 while connecting respective bases. By the ON/OFF pulse of the frequency oscillator 2, the transistors 3 and 4 for driving alternatively repeat ON/OFF and execute ON/OFF control to the gate voltage of the FET transistor 5. Thus, the FET transistor 5 for switching is turned ON/OFF and a direct current to flow to a transe circuit is converted to an alternative current and outputted. During switching, the inverse bias is sent out to the base voltage of the FET transistor 5 by the inverse bias circuit 7.

IPC: H03G3/12
Filed: 1984-12-18
Abstract: PURPOSE:To improve the residual noise characteristic of a voltage gain control circuit by using DC feedback so as to suppress the fluctuation of an output DC voltage attended with the gain control. CONSTITUTION:An input signal is converted into a current I by a transistor (TR) Q3. The current I is branched by TRs Q1, Q2. A DC feedback circuit 1 is connected to the TR Q2. The DC feedback circuit 1 compares the signal output with a reference voltage to make the collector voltage of the TR Q2 constant so that the output DC level is always constant. Through the constitution above, the generation of noise due to excess circuits is eliminated and the gain is decreased and then the noise is decreased.

Title: Malfunction preventing system for station discrimination circuit
Inventor: NONAKA KENJI
IPC: H04Q1/30
Filed: 1990-10-04
Abstract: PURPOSE:To prevent malfunction even when a mis-output is caused from a read filter due to mechanical shock and vibration by outputting a detection signal from a gate circuit only when a reception signal and an output of the read filter exist simultaneously in a station discrimination circuit in a selection signal receiver. CONSTITUTION:A reception signal of a specific frequency is inputted to an amplifier 1, in which the signal is amplified up to a prescribed level, and then branched into two, the one is inputted to a read filter 2 passing only a specific frequency signal and the other is inputted as it is to a 2nd detection circuit 4. An output of the read filter 2 is inputted to a 1st detection circuit 3. The detection circuits detect an input signal and output logical 1 when the level of the input signal is a prescribed level or over. Outputs of both the detection circuits are ANDed by an AND gate 5 and the result is outputted to a reception start section as a detection signal. When no reception signal is inputted and the read filter causes a mis-output, the output of the 1st detection circuit 3 goes to 1, but the output of the 2nd detection circuit 4 goes to 0 and the output of level 1 from the 1st detection circuit 3 is blocked by the AND gate 5 and then no detection signal is outputted.

Filed: 1984-12-18
Abstract: PURPOSE:To reduce mixing of switching noises generated in chopper operation to video signals by synchronizing period of a chopper with a horizontal synchronizing signal and making at least one of rising or falling action in the blanking time of the horizontal synchronizing signal. CONSTITUTION:When a horizontal synchronizing signal is supplied to an input terminal at time 52, an AND circuit 3 takes the logical product of a direct signal from an AND circuit 32 and a signal delayed by a delay circuit 34, and generates a single pulse synchronized with rising of the horizontal synchronizing signal, and a transistor 37 becomes on. Consequently, a transistor 14 also becomes on, an output voltage V0 rises from a time t2. When the output voltage Vo becomes higher than the set voltage Vref of a reference voltage source 26, transistors 37 and 14 become off. Thus, on/off-control of the transistor 14 is made synchronously with the horizontal synchronizing signal, and specified DC current Vo can be obtained.
