Abstract: A method for manufacturing a semiconductor module incorporated with an optical isolator making use of a Faraday rotator formed of a magnetic garnet film in which a magnetically saturated condition is maintained even without any external magnetic field, in which, at the time the magnetic garnet film is exposed to a temperature of 100° C. or more in a step during manufacture, an external magnetic field is applied in the same direction as the direction of magnetization of this magnetic garnet film. This manufacturing method has an advantage that the high-coercivity film magnetic garnet film is not removed from its magnetically saturated condition even when heating steps are present in the course of manufacture.

Abstract: A technique for improving a ruggedness of a transistor against breakdown is provided. In a transistor of the present invention, a height of filling regions is higher than that of buried regions, so that a withstanding voltage of the filling regions is higher than that of the buried regions. Therefore, since avalanche breakdown occurs in an active region, causing an avalanche breakdown current to flow through the active region having a large area, current concentration does not occur. As a result, a ruggedness of an element against breakdown is increased.

Abstract: A constant-current battery charger includes a power supply for supplying a charge current to a secondary cell, and a current monitor for monitoring a charge current being supplied to the cell. A controller is included for varying the charge current in accordance with the monitored charge current. The controller calculates a current difference between a predetermined target current and the instant charge current, and generates a demand of varying the charge current at a first charge rate when the current difference is out of a predetermined range, and varying the charge current at a second charge rate when the current difference is within the predetermined range. The controller generates the demand repeatedly at regular or varying intervals for varying the charge current. The first charge rate is set to be higher than the second charge rate in order to make a rapid charging until it comes close to the target current.
