Title: Constant-voltage constant-frequency power source
Inventor: CHIFUKU TOSHIHITO
IPC: H02M7/48
Filed: 1984-12-10
Abstract: PURPOSE:To reduce the sizes of a transformer and an AC filter by driving a self-excited power inverter by a high frequency, and converting a high frequency AC voltage at the output side of a transformer to a commercial AC voltage. CONSTITUTION:A DC voltage applied from a power converter 1 or a storage battery 7 is switched, for example, by a high frequency of 20kHz by a single- phase self-excited power inverter 3 to convert to a high frequency AC power. The high frequency AC power output from the inverter 3 is converted to a voltage corresponding to the commercial frequency AC output voltage. Further, the output voltages of AC frequency converters 5A-5C of phases are independently controlled to be fed back to convert the 3-phase high frequency AC voltages into 3-phase 50Hz commercial frequency AC sinusoidal wave output voltages and to output it. Thus, since the inverter is operated in high frequency, the sizes of a transformer and an AC filter of components can be reduced.

Title: Piezoelectric resonator
Inventor: TANAKA MITSURU
IPC: H03H9/17
Filed: 1990-09-28
Abstract: PURPOSE:To suppress only a harmonic vibration component almost without obstructing a fundamental vibration component by forming an air gap whose size is lambda/3-lambda/30 to a region inserted between a couple of exciting electrodes in the inside of a piezoelectric body. CONSTITUTION:An air gap 14 is formed in the inside of a piezoelectric body 11. The air gap is located in a region inserted between a couple of exciting electrodes 12,13 and its size is selected in a range of lambda/3-lambda/30 (A is a wavelength of a fundamental vibration). Since the propagation loss by the air gap 14 is increased as the frequency becomes higher, the fundamental vibration 15 is not much suppressed, but a standing wave of a 3rd harmonic vibration 16 is not almost or not entirely caused. Moreover, 5th harmonic vibration components or over are suppressed more by the air gap 14. Consequently, a piezoelectric resonator 10 excites only the fundamental vibration 15 depending on the characteristic.

IPC: F28D9/00
Filed: 1990-09-28
Abstract: PURPOSE:To prevent corrosion of a heat exchanging plate by a method wherein a length of an end plate at a ground part is elongated by more than a specified size from a heat exchanging plate. CONSTITUTION:A stacked heat exchanger is constructed such that a plurality of heat exchanging plates 1 are piled up with every one plate being turned by 90 deg., respectively, and end plates 11 and 12 larger than the heat exchanging plate 1 are closely contacted with both ends, and fluid inlet pipes 5, 6 and outlet pipes 7 and 8 are fixed to the end plate 11. The heat exchanger is mounted on an iron mounting table 9. Since an end part of the mounting table 9 for the end plates 11 and 12 is elongated by more than 15mm from the heat exchanging plate 1, the heat exchanging plate 1 is not immersed in the condensed water droplets or rain water 10 accumulated in the mounting table 9 and thus a promotion of corrosion can be restricted. In addition, since the heat exchanging plate 1 and the mounting table 9 are not directly contacted, corrosion with electrolytic corrosion is not generated, either.
