Abstract: PURPOSE: A self-sustaining oscillation circuit including a power amplifier and a PWM(Pulse Width Modulation) modulator capable of input line regulation is provided, which solves a discordance between a resonant frequency of a transformer and a frequency of a driving circuit. CONSTITUTION: An E class power amplifier(1) is connected to an input port, and an output of the power amplifier is supplied to an LC filter(2) comprising an inductor L and a capacitor C. A transformer(6) outputs the first signal to drive a load(7) by receiving the output of the LC filter and outputs the second signal for a self-sustaining oscillation of the whole circuit through resistors R1 and R2 serially connected each other. A pulse shaper(4) is connected to a contact point of the resistor R1 and R2, and forms a saw tooth wave corresponding to a self-sustaining oscillation frequency using an output signal of the transformer. An error amplifier(5) generates an output voltage signal by comparing a predetermined load current value with a real current value of the load. A PWM modulator modulates a pulse width of the self-sustaining oscillation signal according to the saw tooth signal formed in the pulse shaper and a comparison signal of the error amplifier, and an input line regulation of the whole circuit is performed by the modulated self-sustaining oscillation signal.

Abstract: PURPOSE: A supplying method of heat to a vulcanization mold for tires is provided to improve the physical property of a completed tire by regularly supplying heat to a vulcanization mold and a bladder for vulcanizing the outside and the inside of a tire respectively. CONSTITUTION: A specific amount of steam is supplied into a bladder(10) to expand the bladder. The inside of a mold(22) is kept empty without green tires. Then, a valve(20) is opened, and 15kg/cm2 of high-temperature saturation steam is supplied into a dome(21) to preheat the mold. After that, the pressure is removed from the bladder. The mold is opened, and green tires are supplied into the mold. The bladder and the dome are heated. The green tires are closely adhered to the inside of the mold by expansion of the bladder. Thereby, the green tires are molded to tires. The mold has temperature higher than one of the bladder. The vulcanized degree of the inside and the outside of the green tires is different, and the physical property of the completed tires is irregular. To prevent this, 16-30kg/cm2 of ordinary-temperature inactive gas is supplied into the dome to balance the temperature of the mold with one of the bladder. The temperature deviation between the upper and the lower dome is reduced when condensate remaining at the lower part of the dome is drained out. If the temperature of the dome is lower than one of the bladder, the valve is opened to supply heat into the dome. Otherwise, another valve(30) is opened to reduce the temperature of the dome. Therefore, regular heat is supplied to the bladder and the physical property of tires is enhanced.
