摘要： Conventionally, there is a problem that it is impossible to provide an analog signal detecting circuit having high reliability and long lifetime under a bad environment since a photocoupler is used for electrical insulation of a digital signal. Then, an analog signal detecting circuit is provided with a carrier wave generating unit for generating a carrier wave, a pulse width modulating unit for pulse width modulating an analog signal inputted from the signal input terminal by using the carrier wave generated by the carrier wave generating unit and for outputting a digital signal, a reverse level shift HVIC for transmitting the digital signal from one power supply system to the other power supply system, and a demodulation unit for demodulating the digital signal transmitted to the other power supply system into an analog signal and for outputting it to a signal output terminal. As a result, even in the case where reference potentials are different from each other at signal input/output terminals, an analog signal can be detected.

摘要： In the present invention, when a power module is soldered to a heatsink, steam which is temperature-adjusted to at least the melting point of a solder is introduced from a steam generating tank into the flow path provided in the heatsink, the heatsink is heated and the solder is melted. Inert gas is introduced into a soldering tank from another route so as not to mix with the steam supplied to the heatsink. Voids in the solder are reduced and condensed by pressure regulation and as a result the negative impact of voids is eliminated.
