Title: Power supply
Inventor: NAKANO TOMOYUKI
IPC: H02M7/48
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of an undue stress in a switching element without requiring an intricate control circuit by starting operation of a self-excited inverter circuit, after a smoothing capacitor is charged with a predetermined voltage. SOLUTION: A high-frequency signal generated by turning transistors Q1, Q2 on/off is fed back, as a drive signal for the transistors Q1, Q2, to the gate terminal through a current transformer T1, in order to sustain the on/off operation. A self-exciting inverter circuit is constituted of the transistors Q1, Q2 and the current transformer T1. When the transistor Q1 is turned on, a capacitor C4 is discharged through a resistor R2 and the transistor Q1 and the operation of a starting circuit 1 is stopped. Since operation of the transistors Q1, Q2 can be started after the capacitor C1 is charged with a predetermined voltage, generation of undue current stresses in the switching element can be prevented without the use of a complicated control circuit.

Filed: 1990-10-09
Abstract: PURPOSE:To reduce residual air bubbles and to decrease an optical loss by incorporating dopant having lowering activity of the vitrescence temp. on to the piled layer of the base plate. CONSTITUTION:On to the base plate A, fine particles of glass are piled by flame piling method and piled layers B, C are formed successively. When the piled up layer C is vitrescent transparently by doping with Ge and Ti, the difference of the refractive index is produced between the core layer C' and the clad layer B'. Namely, an optimum vitrescence temp. (Tc) of the piled layer C are different from each other to be Tc<Ta, and in the case of forming the piled layer C, other than the main dopant of Ge and Ti effective for increasing the refractive index, the other auxiliary dopant capable of lowering the vitrescence temp. of the piled layer are simultaneously doped. Consequently, the optimum vitrescence temp. of the formed piled-layer C is changed from Tc to Tc- T and is dropped lower than Tc. By this means, the residual air bubbles are reduced and the reduction of the optical loss is attained.
