Title: Power amplifier circuit
Inventor: TAKI YOICHIRO
IPC: G11B21/10
Filed: 1986-04-22
Abstract: PURPOSE:To improve crossover distortion by adding a voltage limit circuit based on a transistor(TR) to an operational amplifier. CONSTITUTION:A TR 18 is used for the connection of its base to the earth, a fixed potential value is applied to the base, its emitter is connected to the base of a TR 9 and its connector is connected to the inversional input terminal of an operational amplifier 3. A TR 19 is also connected to an operational amplifier 4. When an input signal 1 is increased, the output voltage of the amplifier 3 is reduced and the TR 9 is turned off, the TR 18 is turned on and a feedback loop is formed between the input and output of the amplifier 3. When the signal 1 is reduced, the TR 19 also executes similar operation and a feedback loop is formed between the input and output of the amplifier 4. Thus. crossover distortion can be sharply improved by adding the TRs 18, 19.

SOLUTION: A lighting circuit device 6 is formed for using an inverter transformer IT, having a leakage inductance ratio equal to or less than 2.5%, and a fluorescent lamp L having an external electrode is connected to the output side of the transformer IT. In this circuit configuration, when voltage is applied to drive a pulse generation circuit P, a switching element SW is turned on and off, thereby causing an inverter circuit IC to operate. Pulse wave power having voltage between 1 kV and 3 kV and a frequency equal to or less than a value between 20 and 50 Hz is applied from the inverter circuit IC to the external electrode of a glass bulb, having an inner diameter equal to or above 5.1 mm. In this case, the applied voltage is low, and the temperature rise of the bulb can be restrained.  At the same time, the deterioration of a brightness characteristic during a lighting time is restrained.

Abstract: PURPOSE:To omit an exclusive switch circuit and to shorten a gate delay time by setting an internal address signal at a latch circuit for external address signal as necessary and performing changeover between the external and internal address signals. CONSTITUTION:A switch means 104 inverts an external address signal via an inverter 104c and turns on and off a transmission gate 104a with control signals phi' and the inverse of phi' to set the external address signal at a latch circuit 1. Thus the external address signal is set under a latch state. The circuit 1 secures a loop connection between NAND gates 1a and 1b via an input terminal of one of both gates 1a and 1b. While the complementary refresh address setting signal RA1 and RA2 are inputted to the other input in a refresh state. In this case, the complementary signals phi and the inverse of phi' are set at 0 and 1 respectively so that both signals RA1 and RA2 can be set at the circuit 1. Thus the means 104 is turned off for separation of the external address signal. Then the address input is switched to a refresh address.
