摘要： A high-voltage transformer includes a bobbin that holds a core at its center. This bobbin has eight winding grooves arrayed along the central axis of the core. A primary coil is wound around each of two outermost winding grooves with a predetermined number of turns. A secondary coil is wound around the six winding grooves near the center with a predetermined number of turns, which are distributed among these winding grooves. The cathode of a diode is connected through a terminal to one end of the secondary coil where the winding starts, while the anode of another diode is connected through another terminal to the other end of the secondary coil where winding ends.

摘要： A flyback transformer has a high-voltage bobbin. The bobbin is provided with a focus-pack connection terminal in addition to electronic-component mounting terminals. The focus-pack connection terminal is connected to one of the electronic-component mounting terminals which provides the desired high voltage. When the desired voltage changes, the focus-pack connection terminal is simply connected to another one of the electronic-component mounting terminals corresponding to the changed voltage, easily changing the focus-pack supply voltage.

摘要： An information recording disc has a control signal such as an address signal pre-recorded on a guide track which is pre-formed on the information recording disc at a position different from a track position where an information signal is to be recorded.

摘要： A high voltage generation circuit including a transformer, the transformer having a primary winding having a primary inductance; a power supply for supplying a voltage to the primary winding of the transformer; a switching element for controlling current flowing through the primary winding of the transformer from the power supply; and a resonance capacitor which resonates with the primary winding of the transformer when the switching element is off, so that a flyback pulse is generated. The circuit has a distributed inductance and a resonance capacitance. The switching element is controlled so as to be switched on nearly at the bottom of a quiescent ringing pulse which is produced by a resonance of the primary inductance of the transformer with a capacitance included in a circuit connected to the primary winding of the transformer, after the flyback pulse is generated.

摘要： Fine particles of a metal such as copper and silver can be obtained by reducing the corresponding metal compound solution with one or more reducing agents selected from the group consisting of L-ascorbic acid, L-ascorbate, D-erythorbic acid and D-erythorbate. Silver-palladium composite particles can also be obtained similarly by employing a colloidal palladium liquid and a silver compound solution.

摘要： The number of layers of a secondary winding of a flyback transformer for use in a PWM controlled high-tension voltage generator is increased to six or higher. The distributed capacitance of the flyback transformer is thus decreased, the frequency of ringing is increased, and the pulse width of a flyback pulse is narrowed. The timing of the on-operation of a control FET is expedited, and the input current to the flyback transformer is lowered. A compact and power-saving flyback transformer thus results.

摘要： A control circuit for controlling the erasing of an information signal recorded on an optical disk such that the information signal is erased except for the vertical blanking interval and for the interval corresponding to the address signal of the information on the disk. The rest of the information signal including the horizontal synchronizing signal is erased either continuously or intermittently or is not erased. The circuit produces a control signal which assumes a first logical state for enabling the erasing and a second logical state for disabling the erasing responsive to a horizontal synchronizing signal, a vertical synchronizing signal and a command signal commanding the erasing of a particular information signal on the disk.
