Filed: 1990-06-20
Abstract: PURPOSE:To prevent jitter from being generated by the existence of phase difference between both clock signals by controlling a frequency changing means so that the phase of a regenerative clock signal can be same as that of an oscillated clock signal. CONSTITUTION:A clock oscillating means 1 oscillates the clock signal corresponding to the regenerative clock signal taken out of a signal recorded in a recording medium, and this oscillated clock signal is supplied at the same phase as that of the above-mentioned regenerative clock signal. A phase difference detecting means 5 detects the phase difference between the regenerative clock signal and the oscillated clock signal and based on the phase difference detected by the phase difference detecting means 5, a frequency changing means 2 is controlled so that the phase of the regenerative clock signal can be same as that of the oscillated clock signal. Thus, the phase of the regenerative clock signal can be coincident with that of the oscillated clock signal.

Abstract: PURPOSE:To increase the spread of the reproduction sound as well as the ambience by providing the desired delay time difference among the reproduction stereo signals produced through plural number of speakers by means of the balancer resistor of single operation plus the stereo signal delay part. CONSTITUTION:The right and left stereo signals supplied to terminals 1 and 1' are supplied to delay parts 2FR and 2RR plus 2FL and 2RL each. The delay time of parts 2FL-2RL are decided by repetitive frequency fc of the clock pulse generated at clock pulse generation part 3 plus delay parts 2FL-2RL composed of the charge transfer elements. And the delay parts supply the input stereo signals to power amplifier part 5 with the delay time mentioned above. Frequency fc is varied by the resistance value of resistor 4, and the resistance value is changed according to the turning direction of a piece of the knob. Accordingly, the control can be given to the arrival time of the reproduction sound sent from the ambient speakers even in the comparatively narrow space. Thus the spread of the reproduction sound and the ambience can be increased.

On the other hand, thermal energy imparted to feed air side fins 58 is transmitted to the surface plate on the exhaust side, and increased by the thermoelectric element to warm an exhaust side fins through other surface plate. Indoor air which has been introduced from the inside of the room into an exhaust duct case 16 makes contact with the exhaust side fins, robbing the exhaust side fins of heat and discharged out of the room. On the other hand, when the inside of the room is heated in winter season, a current flowing to the thermoelectric element is caused to flow in a manner reverse to the above described case, whereby the thermal energy of the exhaust air is drawn up by the thermoelectric plate through the surface plate, and is transmitted to the feed air. The feed air which is allowed to have a temperature which is equal to the room temperature is introduced into the room.
