Title: Overvoltage protection circuit
IPC: H03F1/52
Filed: 1992-03-13
Abstract: PURPOSE:To eliminate the application of an overvoltage without necessitating special selection of a diode by forming a voltage less than a power supply voltage used for an amplifier circuit by at least one diode stage and suppressing an input terminal voltage based on the decreased voltage. CONSTITUTION:When a voltage higher than a voltage fed to a high voltage power terminal 10 is applied to an input terminal 11, a PNP type transistor (TR) 1 is operated and current flows from the input terminal 11 through the TR 1 and a voltage of the input terminal 11 of an amplifier circuit 7 is limited within a high voltage applied to the terminal 10. Similarly, when a voltage lower than a low voltage fed to a low voltage power supply terminal 13 is applied to the terminal 11, an NPN TR 2 is active and a current flows from a ground terminal 12 through the TR 2 and a voltage at the input terminal 11 of the amplifier circuit 7 is limited within a low voltage fed to the terminal 10. Thus, the special selection of constant voltage diodes 3, 4 is not required and application of an overvoltage to the amplifier circuit 7 is avoided.

The PC slab is fixed to the strut 5 on a truck 3 with a fastening jig 6, sent into a high-temp. and high- pressure curing furnace by the wheels 4, and cured. An alkaline component such as Ca(OH)2 oozing out from the PC slab during curing forms alkaline water with the condensed water deposited on the PC slab, hence the decorative sheet 2 is corroded by the alkali, and the quality is deteriorated. To prevent the phenomenon, the PC slab 1 is vertically or almost vertically supported on the truck 3. As a result, alkaline water is sufficiently trickled and not deposited on the surface of the decorative sheet, and the beautiful PC slab free of alkali corrosion on the decorative surface is easily obtained.
