Title: Power converter
Inventor: ASAEDA TAKEAKI
IPC: H02M5/458
Filed: 1987-06-05
Abstract: PURPOSE:To improve conversion efficiency by composing a first inverter on the input side of a first transformer of a current control type, mounting a third inverter on the input side of a second inverter and charging a battery through a second transformer and a third diode rectifier. CONSTITUTION:A switch 25 is turned OFF on normal operation. Consequently, the AC voltage of an AC input power 1 is rectified by a first diode rectifier 2, and AC currents are controlled to a sinusoidal shape through a reactor 20 by a first inverter 8a. The reactor 20 is set up on the input side of the first inverter 8a, and the first inverter conducts current control type PWM control. Second and third inverters 13 and 21 perform voltage control type inverter operation to an input voltage source by PWM control at high frequency.

Title: Stripping method for semiconductor chip and its equipment
Inventor: SAKURAI MASAHIKO
IPC: H01L21/68
Filed: 1985-06-28
Abstract: PURPOSE:To make it easy to strip a semiconductor chip, by adsorbing the semiconductor chip under the condition that the bond strength of adhesive agent is decreased by heating the sheet of the lower surface of semiconductor chip. CONSTITUTION:The semiconductor chip 2 to be stripped is set right above the heater 9 by moving the ring 6, and the sheet 1 of the lower surface of semiconductor chip 2 is adsorbed by the adsorbing nozzle 7. The sheet 1 is heated by rising the temperature of the heater. By this the viscosity of the adhesive agent spread on the sheet is decreased, and the bonding strength is reduced. Therefore, the semiconductor chip is easily stripped when the adsorbing force is applied by the adsorbing collet 3. The semiconductor chip 2 adsorbed by the adsorbing collet 3 is mounted on the lead frame 10. Therefore, the stripping of the semiconductor chip is possible without pushing out the semiconductor chip in the direction of the adsorbing collet 3 by the pushing bar.
