摘要： An optical module and method in which an optical element (32) and an optical waveguide (34) are formed on a silicon substrate (31) so that an optical axis of the optical element coincides with an optical axis of the optical waveguide. Metallized films (41, 42) are formed on the silicon substrate and on the optical waveguide respectively, and these metallized films are bonded to each other by mutual diffusion of their atoms.

摘要： A switching power source control circuit comprising a comparator, a thin-out-processed pulse generator, a thinned-pulse detector, and a reset speed regulator, wherein: the comparator compares an output signal of an error amplifier with a variable reference voltage generated by the reference voltage regulator to generate a signal for performing thin-out operation in accordance with a voltage difference between the output signal of the error amplifier and the reference voltage; the thin-out-processed pulse generator generates thin-out-processed pulses on the basis of the output signal of the comparator; the thinned-out pulse detector detects the generation of thinned-out pulses or driving pulses while always monitoring the thin-out-processed pulses generated from the thin-out-processed pulse generator, and changes the reference voltage of the reference voltage regulator in the case where the thin-out rate is in a range of from 0 to 1/2 in the direction to make it difficult to perform thin-out operation to thereby prevent continuation of thin-out operation whenever one thinned-out pulse is detected; and the reset speed regulator resets the reference voltage of the reference voltage regulator to an initial value in accordance with the output signal of the error amplifier.
