Abstract: In the production of aspheric seamless capsules, seamless capsules (C1) comprising a filler covered with a coating are first provided and dried by means of dryer (12) until the solvent content of the coating becomes a given value. Subsequently, the seamless capsules are heated by heater (38) so as t o semi-solate the coating. Thereafter, the heated seamless capsules are molded into given aspheric form by molding unit (52) such as compression molding equipment. Since the dried coating of spherical seamless capsules is used in semi-solated form in the above manner, the elasticity thereof is reduced and the stress relaxation time is short. Accordingly, the molding operation can be accomplished within a short period of time, and the restoration to original spherical form can be avoided. Further, the property change in semi-solated form is slight, so that the temperature control is easy. After the molding into aspheric form, any drying is not needed, or the necessity thereof is slight. Therefore, the probability of crimpling of coating surface is low, a nd the degree of morphological dispersion is low.

Title: Adaptive resonant switching power system
Inventor: TSUI PING
IPC: H02M3/338
Filed: 2003-12-31
Abstract: A resonant switching power system operates with two resonant frequencies. A  first frequency depends on the secondary leakage inductance of an output transformer and capacitor. The first frequency varies with changes in the load because load changes alter the leakage inductance. A second resonant frequency depends on the gate source capacitance of two MOSFET power devices in the circuit and the leakage inductance of the circuit's driving transformer. Power is thereby supplied that is always in phase with the load so that switching in the power supply occurs when current is near zero. High thermal efficiency is thereby achieved.
