Abstract: A ballast for discharge lamp. The ballast for discharge lamp for utilizing high frequency voltage is generated by alternatively switching two switching elements to light the discharge lamp. The ballast includes a primary winding of a switching transformer to which the high frequency voltage is applied; a secondary winding of a switching transformer for alternatively switching the two switching elements according to reverse electromotive voltage generated by application of high frequency voltage to the primary winding; and a stabilizer for stabilizing reverse electromotive voltage generating at the secondary winding.

Abstract: A patterned tape attached to a semiconductor chip in a chip scale package enhances process reliability in manufacturing of the chip scale package. A shape of the beam leads concentrates stresses in the part of the beam lead where the beam lead should be disconnected during the bonding of the beam leads to the chip bonding pads, and therefore, the part to be expected to be disconnected disconnects without damaging other parts of the beam lead. In addition, the reliability of a chip scale package is enhanced, because the beam lead attached to the chip bonding pad has little chance of being damaged during bonding.

Abstract: A fluorescent lamp lighting circuit is disclosed in which an instant lighting is possible, and a high reliability is ensured. Further, the circuit is compact, and the cost is low. The fluorescent lamp lighting circuit according to the present invention includes a discharge circuit section including a choke coil serially connected to a filament of a fluorescent lamp. It further includes a lighting circuit section connected serially to the filament and the choke coil so as to be turned on at certain intervals by supplying the power, and so as to be turned off after the starting of the glow discharge of the fluorescent lamp. It further includes a protecting circuit section for turning off the light circuit section after certain repetition of on/off operations of the lighting circuit section.
