Abstract: PURPOSE:To obtain silencing effect effectively, while maintaining a speaker at a sufficient low temperature. CONSTITUTION:An active muffler device is constitution by a nearly cylindrical insulator 13 by which an exhaust pipe 11 is enclosed, a nearly cylindrical extended pipe 12 by which the insulator 13 is enclosed, a close part 14 for closing the insulator 13 and the extended pipe 12, a speaker box 15, and a speaker 16. The insulator 13 is maintained in a low temperature without directly heating by radiating heat of an exhaust pipe 11 since outside air passed in an outside air passage 18. Therefore, the speaker 16 is maintained in a low temperature sufficiently. Since an acoustic passage 19 is formed in a shape having the inclining angle which the close part 14 is 45+ or -5 deg. in relation to the shaft of the exhaust pipe 11, noise which is generated from the speaker 16 achieves in an interaction region without deteriorating output characteristic, so that silencing is achieved effectively.

Filed: 1990-11-29
Abstract: PURPOSE:To simplify the circuit constitution inexpensively and to detect accurately even a heterodyne signal including a standard NTSC signal and noise or the like by detecting a phase difference between a color clock and a monoclock. CONSTITUTION:A color clock locked to a burst in a video signal and a monoclock locked to a horizontal synchronizing signal are subjected to 1/N frequency division by a counter 11 and outputs are compared by a comparator 12.

Filed: 1990-11-29
Abstract: PURPOSE:To distribute comfortable air to all the corners of a room without generating rasping sound by driving a wind direction blade with a wind direction blade drive means when a fan or an air supply means reaches a preset rotational speed. CONSTITUTION:A control means 30 sets intermittent operation of a compressor in conformity with room temperature and a rotational speed of a fan 7 which is a means 1 to supply air and compares the fan's rotational speed detected by a rotational speed detection means 2 with a preset rotational speed and drives the means 1 to supply air so that both valves may be identical to each other. A wind direction blade drive means 6 drives a wind direction blade 5 and changes the direction of forced air. The control means 30 outputs a control signal only when the preset rotational speed is identical to the detected rotational speed of the fan when driving the wind direction blade drive means 6 and moves the wind direction blade 5 little by little. Due to this construction, the control means 30 sets a specified rotational speed and allows the rotational speed detection means 2 to detect the rotational speed of the fan which is the supply air means 1 and outputs a control signal to the supply air means 1 so that the preset rotational speed and the detected rotational speed may be identical to each other, thereby generating comfortable forced air.
