Abstract: PURPOSE:To reduce the software, to decrease the address detecting time and the number of components by connecting directly a Y address line of a key matrix to an input port of a CPU so as to eliminate the need for the scanning of the Y address. CONSTITUTION:X address lines X0-X15 connected to output ports P10-P13 of a CPU1 via a decoder 2 as a conventional device and the Y address lines Y0- Y7 are connected directly to input ports P20-P27 of the CPU1 via a resistance unit 4.

When the key is depressed, the cross point of the X and Y is connected and the Y address line is brought into the L level, then the CPU1 supervises the input ports P20-P27 and recognizes the Y address brought into the L level. Thus, the CPU1 can recognize the depressed key from the state of the output and input ports at that time.

Title: Electronic starter for fluorescent lamp
Inventor: TEI HIDEHARU
IPC: H05B41/18
Filed: 1989-05-11
Abstract: PURPOSE: To provide a compact electronic starter having compatibility with a glow starter by connecting a triac to a fluorescent lamp lighting circuit, and providing a voltage switching element, an electropositive heat resistance, and a time constant circuit in a triac ignition circuit. CONSTITUTION: As a power switch SW of a fluorescent lamp circuit gets continuous, a capacitor 4 is charged through an electropositive heat resistance 2 and a resistance 3, and a gate of a triac 1 is ignited through a voltage reactive switch element 5. The triac 1 then gets continuous, a current flows through a filament at both ends of a fluorescent lamp to heat the filament. In this condition, as a resistance value of the electropositive heat resistance 2 becomes higher by heat generation by the circuit current, a charge time constant to the capacitor 4 through the resistance 3 becomes larger. While heating to the electropositive resistance 2 is continued, therefore, ignition phase control of the triac 1 continues, while a triac energization current flows.  As the continuity current to the triac is disconnected at a phase voltage to cause a self- maintaining current or less, an excitation voltage is generated at both ends of the fluorescent lamp at that instant, thereby the fluorescent lamp is lighted.
