Abstract: A propagation delay time of a cable assembly is measured by calculating a half of a time difference between a branch point of time-dependent variations of amplitude of reflection coefficient obtained by connecting a first connector with both terminals open-circuited and a second connector with one terminal short-circuited to a conversion adaptor in turn and a branch point of the time-dependent variations of the amplitude of reflection coefficient obtained by connecting one terminal of the cable assembly with other terminal connected to the first connector and one terminal of the cable assembly with other terminal connected to the second connector to the conversion adaptor in turn.

Abstract: A cam groove in a shuttling mechanism for shuttling a slide piece is formed into a generally S-shape, in order to provide a long shuttling distance of the slide piece which dispenses one by one coins stacked and stored in a coin tube, without sizable design changes of component parts.

Abstract: A coin discharge device has a removable coin tube cassette and an empty sensor 5 for accurately detecting the presence of coins within the coin tubes. A sensor mounting 30 is designed to withdraw the sensor 5 from the cassette accommodation part 22 when the coin tube cassette is removed from the device. However, when the coin tube device is inserted into the cassette accommodation part 22, the sensor mounting 30 moves the sensor 5 into the accommodation part 22 so that it abuts one side of the coin tube cassette to sense coins therein.

Abstract: The cooling device including a cold plate having an inside water passage through which a cooling water passes and having one surface provided with a cooling element corresponding to an integrated circuit element, a housing for fixing the cold plate to a substrate so that the cooling element is kept in close contact with the integrated circuit element, and a water leakage sensor provided inside the housing, is disclosed.
