Abstract: PURPOSE: To insure the use of a low-temperature heat source by providing a refrigerant pressure booster between a low temperature generator and a condenser.  
     CONSTITUTION: A high-temperature generator 1 having a heater 2 heats to decompose dukyte dilute solution for separating refrigerant, combusts the refrigerant vapor fed out again, heats to decompose intermediate liquid for separating refrigerant The high-temperature generator 1 having a heater 2 heats to decompose diluted solution for separating refrigerant and combusts fed-out refrigerant as heat source again. A low-temperature generator 3 heats to decompose intermediate liquid for separating refrigerant. The refrigerant flowing in from said generators 1 and 3 is condensed and cooled by a condenser 4. Said low temperature generator 3 and condenser 4 are intercommunicated by a communicating pipe 19. A refrigerant pressure booster 20 such as centrifugal type gas compressor is provided in the medium portion of said communicating pipe 19 to lower temperature and pressure in said low-temperature generator 3. The temperature and pressure of said high- temperature generator 1 lowers in proportion to the refrigerant generating temperature and pressure of said low-temperature generator 3. Therefore, a lower temperature heat source can be used than conventional heat sources.

Title: Base metal powder for ceramic capacitor electrode
Inventor: FURUKAWA OSAMU
IPC: C23C18/32
Filed: 1987-06-23
Abstract: PURPOSE: To obtain low-cost base metal powder easy to be treated by plating the surfaces of first base metal powder as nuclei with a second base metal having a composition different from a first base metal through an electrolytic or electroless method.  
     CONSTITUTION: The surfaces of first base metal powder having mean grain size of 0.1W20μm are plated with a second base metal having a composition different from first base metal powder through an electrolytic or electroless method. Cu or a Cu-Ni alloy is used as the first base metal. Ni is employed as the second base metal, and Ni is used through electroless nickel plating. The quantity of adhesion of Ni is increased exceedingly when the grain size of Cu powder extends over 0.1μm or less, a burning temperature as an electrode is displaced to a higher temperature, and the breaking of the electrode is generated. When the grain size of Cu powder exceeds 20μm, screen printing is made difficult while the continuity of the electrode after sintering is also deteriorated. Accordingly, base metal powder is not oxidized even through a degreasing process in air, and the title electrode sufficiently displays a function as an internal electrode on the main baking of a reducing atmosphere (such as nitrogen), thus acquiring a continuous electrode film.

Filed: 1991-06-26
Abstract: PURPOSE:To provide a transistor structure capable of ultrahigh speed operation while preventing malfunctions such as soft errors so as to improve the reliability of ULSIs and large computers. CONSTITUTION:A transistor composed of a first region (101), a second region (102), and a third region (103) has at least one silicon part including an intrinsic region. The silicon part is bent in a plane or cross section. Therefore, the transistor having the bent structure is irradiated only at a small part with alpha-rays that tend to advance straight. The charge produced by a-ray irradiation is smaller as compared with the transistor's capacitance, and thus it is possible to prevent malfunction and realize ultrahigh speed operation.

Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To obtain an optical transmission system that can reduce a nonlinea optical effect as to a bit pattern of an overhead part consisting of a plurality of bits. SOLUTION: A plurality of transmitter side optical transmitters 1031, 1032,..., 103N receive a clock signal 102 with the same frequency and the same phase and transmit optical signals 1141, 1142,...114N whose overhead arrangement positions are changed for each wavelength by respective variable delay sections 107 under the control of a phase control section 126 to a transmitter side WDM device 121. In the device 121, these signals are multiplexed by a wave multiplexing section 123 and transmitted to a receiver side WDM device 133. Receiver side optical transmitters 1381, 1382,...138N receive demultiplexed optical signals.  Since the phase control section 126 deviates the arrangement position of the overhead for each wavelength and the resulting optical signals are transmitted, the nonlinea optical effect of the received optical signals is suppressed and the receiver side can receive the excellent signals.
