Abstract: A semiconductor device is provided with a power module capable of supplying an alternate current to a load, while a direct current is supplied from a battery to the power module for conversion into the alternate current, a cooling member capable of radiating heat generated by the power module, and a mounting member, integrally formed with a spring portion protruding in part therefrom and having elasticity, which allows the power module to be mounted on the cooling member under a state where one surface of the power module is caused to face the cooling member and the spring portion is pressed against the other surface of the power module in opposition to the one surface thereof.

Abstract: A presensitized offset printing plate is identified by its reflected light as one of the known presensitized plates of different light reflective characteristics. White light is casted on a freshly introduced presensitized plate to be tested so as to measure the intensity of the reflected light from the surface of the photosensitive layer thereon in four color signals, which are a magenta signal, yellow signal, cyan signal and black-and-white signal. Then the reflected light is compared in each color signal with the reference data which are inherently determined with respect to known presensitized plates of different light reflective characteristics, whereby the tested presensitized plate is recognized or identified as one of the known presensitized plates. Said reference data, which are different with respect to the known plates, are stored in memory means.
