Abstract: PROBLEM TO BE SOLVED: To reduce the time till an image is outputted by detecting a voltage rise of a power supply of a SW transformer secondary side when a SW of a television receiver is closed to control the timing of power supply to each circuit and of data communication thereby surely and accurately preventing malfunction of each circuit and destruction of components. SOLUTION: A voltage detection circuit 6 detects a voltage rise at a secondary side of a SW transformer when a power SW is closed and gives the detected voltage to a microcomputer 8. The microcomputer 8 gives an ON signal to a constant voltage circuit 7 when the microcomputer 8 detects a voltage required for the constant voltage circuit 7, which applies a voltage to a deflection control circuit 9. After the deflection control circuit 9 receives the required voltage, the microcomputer 8 starts data communication to the deflection control circuit 9. Then the microcomputer 8 gives the ON signal to a high voltage on/off circuit 11, which applies a high voltage to a deflection output circuit 12.

Title: Digital-analog conversion circuit
Inventor: MORI YASUYUKI
IPC: H03M1/74
Filed: 1985-12-25
Abstract: PURPOSE:To speed up the D/A conversion by connecting a drain of a FET or a collector of a transistor (TR) constituting plural load current switch circuits and a source of a common gate FET or an emitter of a common base TR constituting a current/voltage conversion circuit in cascade. CONSTITUTION:Since drains of each FET are all connected to an emitter of a TR Q0, a summing current being the sum of load currents I1-In flows to the emitter of the TR Q0. Since FETs T1-Tn and the TR Q0 are connected in cascade, the output impedance viewed from the drain of the FETs T1-Tn is high and the input impedance viewed from the emitter of the common base TR Q0 is very low. Thus, the drain voltage of the FETs T1-Tn is almost unchanged and the mirror effect due to the gate-drain capacitance is less. Further, the TR Q0 acts like a common base circuit and the feedback from the output to the input is less. Thus, the titled circuit is operated in a high speed.

Title: Production of hot dip sn coated wire
Inventor: DOI SEIICHI
IPC: C23C2/38
Filed: 1988-11-21
Abstract: PURPOSE:To stably produce the hot dip Sn coated wire having excellent surface quality by passing molten Sn to an Sn plating section provided with an angle and running the wire in the direction opposite to this flow, thereby plating the wire. CONSTITUTION:The angle alpha is provided to the Sn plating section in a plating cell 1. This angle alpha is adequately about 5 to 30 deg. with horizontal.
