Abstract: Disclosed are power generation apparatuses. An exemplary power generation apparatus (1) is configured such that water vapor generated in a steam generator (2) is supplied to a scroll expander (3) to drive the scroll expander, wherein: a condensation device (5) is arranged in a discharge path (12) downstream of the scroll expander, the condensation device being configured to mix water vapor having passed through the scroll expander directly with cooling water to condense the water vapor; and the condensation device includes a control unit (10) that performs a control of adjusting the amount of cooling water supply so as to obtain condensed water having a predetermined temperature.

Abstract: An optimum antenna is readily selected from three or more antennas, by means of an existing device which is only capable of switching between two antennas. The device of the invention comprises: a switching device for receiving signals from two antennas as a pair of antenna selected from three or more antennas, and outputting the first signal (DATADET) indicating that receiving is in progress, and the second signal (ANTSEL) indicating which antenna being used for receiving; a judgement circuit for judging which antenna is suitable for receiving and actually being used in the said pair of antenna, on the basis of the said first and the said second signal of the said switching device; a setting circuit for resetting said pair of antenna on the basis of the output of said judgement circuit; and a switching circuit for selecting two antennas which is set by the said setting circuit as a pair and supplying the output thereof to the said switching device.
