Abstract: A vibration control device, while applying Gaussian vibration that matches a target vibration physical quantity PSD to a test piece, makes a corresponding vibration physical quantity non-Gaussian. Using a response vibration physical quantity PSD and a target vibration physical quantity PSD, a control vibration physical quantity PSD calculation generates a control vibration physical quantity PSD for generating a drive signal. A PSD conversion converts the control vibration physical quantity PSD into a control corresponding vibration physical quantity PSD of another dimension. Using the control corresponding vibration physical quantity PSD, a control corresponding vibration physical quantity waveform calculation calculates a control corresponding vibration physical quantity waveform that is non-Gaussian.

Abstract: A multicast network system is provided with a multicast network unit that delivers data between independent multicast network domains. The multicast network unit includes an extraction part for extracting a multicast delivery destination address from received data, a holder part for holding conversion data where the multicast delivery destination address corresponds to a delivery source address, and a judgment part for judging whether the multicast delivery destination address is held and outputting the result of a judgment. The multicast network unit also includes a filtering part which, when the result of the judgment is holding, converts the multicast delivery source address to an arbitrary delivery destination address and, when it is non-holding, discards the received data. The multicast network unit further includes a transmitter part for transmitting data containing the converted multicast address to the domain.

Abstract: In an absorption chiller-heater, warm water in the heat exchanger tubes of an evaporator is heated by spraying solution on the surface of the heat exchanger tubes of an evaporator, and the temperature of the solution is lowered at the same time. As a result, using a conventional low temperature solution pump, high temperature water of around 80.degree. C. may be produced without raising the temperature of the solution. Accordingly, it is not necessary to use heat resisting materials for the solution pump, and corrosion of the materials of the apparatus is less likely to occur. At the same time, since the temperature of the parts is lowered, thermal stress of the materials decreases.
