Abstract: PURPOSE:To efficiently attenuate a part of an original sound waves without especially limiting the frequency band by providing sound wave reflecting mirror, a sound concentrating microphone, and an opposite-phase sound wave radiation speaker. CONSTITUTION:As for a sound wave radiated by a front sound source S, a sound wave which is not cut off by the 1st sound wave reflecting mirror 1 and travels straight and an opposite-phase sound wave which is radiated from the opposite-sound wave radiation speaker 5 are in phase rotation relation of phase delay corresponding to a propagation distance at the position where they are equal in in-air propagation distance. At the position where the propagation distances are made equal, the opposite-phase sound wave from the speaker 5 is matched with the propagation state of the sound wave which travels straight without being cut off by the reflecting mirror 1 and both the sound waves are put together again to cause mutual interference, thereby greatly decreasing the wave motion energy of the sound wave radiated from the front sound source nearby the confluence point.

Title: Ice-based regenerative heat source apparatus and antifreezing control
Inventor: ONO YASUO
IPC: F24F5/00
Filed: 1994-03-30
Abstract: PURPOSE:To prevent freeze in the heat exchanger in air-conditioning operation so as to ensure proper performance of the air conditioning by providing a means of preventing damage to the heat exchanger which is due to freeze of chilled water inside a brine-water heat exchanger at the start of the air-conditioning operation. CONSTITUTION:During air-conditioning operation heat exchange takes place between an antifreeze liquid cooled by a heat source apparatus 1 and cold water returning from the load at a brine-water heat exchanger 2. A timer function is provided to set a period of time for which to put a brine pump in forced operation. A fixed period of time in advance of the start of air conditioning and stopping the heat source apparatus 1 but leaving the heat storage mode effective, the timer function sets a brine pump 17 alone in forced operation. As a result, the water inside a regenerative tank 3 undergoes a phase change to ice by virtue of the heat capacity of the brine and the temperature of the brine increases. Moreover, the operation of the brine pump 17 causes the temperature of the brine to increase through transmission of the motive power of the brine pump 17 to the brine. Thus the chilled water inside the brine-water heat exchanger 2 can be prevented from freezing.

Title: Piezoelectric drive type conveying device
Inventor: NAKAMURA YOSHINOBU
IPC: B65G27/26
Filed: 1986-03-19
Abstract: PURPOSE:To stabilize the vibration of an article to be conveyed to aim at enhancing the efficiency of conveyance and reducing noise, by arranging an a.c. power source for a vibrator such that the output frequency thereof is variable and the output waveform thereof is sinusoidal, thereby the working of adjustment for making the vibrator fall entirely into a resonance condition is simplified so that adjustment of the output frequency is alone required. CONSTITUTION:During adjustment to make a vibrator fall entirely into a resonance condition, when the output voltage of an a.c. power source device 8 is adjusted and then is applied to piezoelectric elements 5a, 5b, with the repetition of the expanding and contracting motions, a bimolf 3 is energized to effect flexural vibration so that an article 6 to be conveyed oscillates circumferential upward and downward inclined directions. When the power source device 8 is manipulated to change the output frequency thereof, the oscillation frequency of the bimolf 3 is made to be equal to the frequency of applied voltage so that the oscillation frequency of the bimolf 3 varies while the vibration of the article 6 to be conveyed also varies. Accordingly, when the these frequencies becomes equal to the natural frequency of the mechanical system, the entire system falls into a resonance condition so that the amplitude of the article 6 to be conveyed becomes maximum so that the conveying speed becomes maximum. Accordingly, since the working of adjustment may be simplified while the waveform of voltage applied to piezoelectric elements 5a, 5b from the power source device 8 is sinusoidal, no high frequency component is generated in the waveform of vibration of the article to be conveyed, thereby the vibration may be stabilized.
