IPC: H03H9/58
Filed: 1992-09-21
Abstract: PURPOSE:To shift a resonance frequency of spurious radiation toward high frequencies on purpose without change of a resonance frequency of the lengthwise vibration of a paper-tablet piezoelectric resonator and to process the resonator simply by cutting off one corner among corners formed by the electrode faces of the paper-tablet piezoelectric resonance plate and side faces employing the lengthwise vibration. CONSTITUTION:Electrodes 4, 5 are provided to one face 2 on the piezoelectric resonator plate 1 and other face 3 opposite to the face 2 in parallel and one corner 6 among corners formed by electrode faces and side faces of the piezoelectric resonator plate 1 is cut out. The effective values of the width and thickness of the resonator are simultaneously changed by cutting off the one corner in this way and the frequency of the spurious radiation is shifted toward higher frequencies without revision of the resonance frequency in the lengthwise direction. In this case, the resonance frequency of spurious radiation is shifted toward higher frequencies as the corner is much more cut off. Or the similar effect is obtained by cutting off the one corner 6 much more further to form a trapezoidal cross section perpendicular to the lengthwise direction of the piezoelectric resonance plate 1.

Title: Hot water heating device
Inventor: OKUMURA YUTAKA
IPC: F24H1/22
Filed: 1990-09-20
Abstract: PURPOSE:To provide a stable hot water heating operation and enable a frequent starting or stopping in operation of a heat source by a method wherein a heating with a heat source is stopped when the hot water temperature in a hot water circulation circuit is higher than the first set temperature and then the heating operation with the heat source is started when the hot water temperature is lower than the second set temperature lower than the first set temperature and a heating stopping time is longer than a predetermined time. CONSTITUTION:As the water temperature at an outlet port of a heat exchanger 6A is higher than the first set temperature of 88 deg.C, an output from a comparator 31 becomes 'L' and a micro-computer 29 sets a signal of an output port P3 to 'L' so as to terminate the combustion of a gas burner 11. Due to this fact, boiling of hot water in a hot water circulation passage or excessive heating can be prevented. At this time, the microcomputer 29 operates a timer TM stored therein. As a combustion stopping time of the gas burner 11 elapses 3 minutes, the timer TM times up, the temperature sensed by a water temperature sensor 16 is lower than the second set temperature 80 deg.C and an output from the comparator 31 becomes 'H', the micro-computer 29 causes the gas burner 11 to perform its combustion in accordance with this sequence. This hot water temperature control is optionally carried out as long as an operating signal is present irrespective of the number of operating signals and a temperature of the hot water supplied to the heaters 19A and 19B is kept at about 80 to 88 deg.C.
