Abstract: PURPOSE:To attain a satisfactory synchronous sound recording and at the same time to improve the operability by counting the time needed for a searching action interrupted in a reproduction mode and having a pause mode for a period equivalent to the difference between said counted time and the set time. CONSTITUTION:The timer time value T1 is compared with a proper time value T2 set previously between the pieces of music.

When the searching job is over, it is checked again whether T1>T2 is satisfied or not. Then the pause state is set up and continued until T1>T2 is satisfied. In other words, if the search time is shorter than the inter-music time, the pause mode is kept for the period equivalent to the difference between both time values. Then the pause mode is released at a time point when T1>T2 is satisfied. Then a sound record start signal is delivered via the line 22 after a fixed inter-music time is produced. At the same time, the muting mode of the music signal output is released.

Abstract: PURPOSE: To convert low level energy into high level energy by coupling one end of a shape-memory alloy member with a piston, engaging the other end with a cylinder and the like, and heating and cooling the alloy periodically. CONSTITUTION: When heated by a hot fluid flowing from an inlet 14, a shape- memory alloy member 4 is extended to return to a predetermined shape to push a piston 6 downward. The pressure of a non-compressive working medium in a cylinder 3 and a working medium sealing container 21 is elevated. A working medium outlet valve 10 is opened to discharge the working medium to a hydraulic drive device 12 through a pressure stabilizer 11 to drive the device. Then the inflow of the hot fluid is stopped by a signal of an electric control assembly 24. When cold fluid is introduced, the shape-memory alloy member 4 is cooled and becomes flexible. The piston 6 is pushed upward by a spring 15 and a working medium pump 20 to compress and deform the shape-memory alloy member. Low temperature waste heat can be used as a prime power by repeating the above-mentioned process.
