A steam turbine cycle of the present invention comprises a high pressure turbine 1, a reheating turbine 24, a boiler 4, feed heaters 6 for heating a feed water to the boiler 4 by a bleed steam from the turbines 1 and 24, a feed pump 12, and a condenser 10, the steam turbine cycle being a single-stage reheating cycle where a working fluid is water and using a Rankine cycle which is a regenerative cycle. A steam temperature at an outlet of the boiler is 590° C. or more. A temperature increase ratio between: a feed-water temperature increase in a first feed heater 7 corresponding to a bleed steam (high-pressure turbine exhaust bleed steam) 22 from an exhaust steam of the high pressure turbine 1; and an average of feed-water temperature increases in second feed heaters 8 where a pressure of the feed water is lower than that of the first feed heater 7; falls within 1.9-3.5.

A vehicle existence annunciator device drives a speaker by utilizing an electric power, which is supplied from an electric power source, to emit an annunciation sound to the outside of a vehicle. The vehicle existence annunciator device includes a counter-voltage-reduction unit configured to enhance a sound pressure level at a frequency, which is apt to linger in a human's ear, when a power supply voltage applied from the electric power source to the vehicle existence annunciator device decreases.

The present invention can reliably adjust the lip-sync between an video and audio at a decoder side, without making the viewer feel strangeness.In this invention, the encoded video frames to which video time-stamps VTS are attached and the encoded audio frames to which audio time-stamps ATS are attached, all received, are decoded, generating a plurality of video frames VF1 and a plurality of audio frames AF1. The video frames VF1 and audio frames AF1 are accumulated. Renderers 37 and 77 calculate the time difference resulting from a gap between the reference clock for the encoder side and the system time clock stc for the decoder side. In accordance with the time difference, the timing of outputting the plurality of video frames, one by one, on the basis of a timing of outputting the plurality of audio frames, one by one. Hence, the lip-sync can be achieved, while maintaining the continuity of the audio.
