Title: Production of mixed gas of carbon monoxide with hydrogen
Inventor: NAKAMURA KENJI
IPC: C01B3/22
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To efficiently produce a mixed gas of carbon monoxide with hydrogen under mild temperature conditions in a simple process and a simple apparatus by decomposing methanol in the liquid phase in the presence of a copper chromium-based Raney type catalyst. SOLUTION: Methanol is decomposed in the liquid phase in the presence of a copper- chromium-based Raney type catalyst to produce a mixed gas of carbon monoxide with hydrogen. An alkali metal compound is effectively contained in the catalyst and/or a reactional liquid. Since the pressurized mixed gas of the carbon monoxide with the hydrogen is obtained by decomposing the methanol in the liquid phase, the resultant reactional product can readily be separated from the methanol which is a raw material. The copper-chromium-based Raney type catalyst can be obtained by developing an alloy comprising copper, chromium and aluminum with an aqueous solution of the alkali metal compound.  As the composition thereof, the amount of the copper is within the range of 0.1-50 wt.%, preferably 30-50 wt.% based on the total weight and the amount of the chromium is preferably within the range of 0.1-50 wt.%, preferably 0.5-20 wt.% based on the total weight. Furthermore, the amount of aluminum is within the range of 30-70 wt.%, preferably 40-60 wt.% based on the total weight.

Title: Eddy current type displacement meter
Inventor: MATSUHASHI KANJI
IPC: H01F5/00
Filed: 1978-12-14
Abstract: PURPOSE: To establish the displacement meter of eddy current type excellent less in the effect of temperature, by constituting the detection coil from the metal with higher electric resistance but lower in the temperature coefficient in comparison with copper and silver, such as Manganin.  
     CONSTITUTION: The eddy current type displacement meter measuring the displacement of vibration for the rotating body such as turbine takes the detection coil as the resonance circuit. The inductance of coil is changed with the distance between the coil and measured metal, causing the impedance of the resonant circuit change. This change is used for the measurement of the distance between the detection coil and the measured object with non-contact method, but this method is subjected to the effect of the temperature of the detection coil. By using the detection coil made of manganin and constantan which have much more specific resistance of the coil material than copper and silver and lower temperature coefficient, excellent eddy current type displacement meter without being effected by temperature can be established.

IPC: F25B15/00
Filed: 1990-06-15
Abstract: PURPOSE:To prevent flashing in an evaporator and preclude the generation of refrigerant mist by a method wherein refrigerant, condensed in a condenser, is precooled before entering the evaporator to reduce the temperature of the condensed refrigerant to the same level as a refrigerant temperature in the evaporator. CONSTITUTION:Refrigerant is absorbed by an absorber 1 and solution, whose concentration is reduced, is supplied to a low-temperature re-producer 3 and a high-temperature re-producer 5 by a solution pump 8 through a heat exchanger 6. When the solution is condensed in both re-producers, high-temperature refrigerant vapor is generated. The refrigerant vapor is sent into a condenser 4 to cool it and obtain condensed refrigerant, however, the temperature of the condensed refrigerant is higher than the inside temperature of the evaporator 2. In order to reduce the temperature, the refrigerant in a refrigerant tank 7 is circulated to a precool device 10 by a refrigerant pump 9. The temperature of the condensed refrigerant, discharged out of the precool device 10, becomes the same level ax the inside temperature of the evaporator 2 and, accordingly, flashing will never be caused when the condensed refrigerant enters the evaporator 2.

Abstract: PURPOSE:To prevent an action from being varied with variations in the gap between a movable side and a fixed side and enable accurate detection of a position, by applying specified input AC voltages to first and second transmitting electrode groups, using the potential difference between first and second receiving electrodes as an output voltage, and measuring and counting the phase differences between the output voltage and the input AC voltages. CONSTITUTION:Two transmitting electrode groups A7, B9 with a positional phase shift of pi/2 therebetween and two belt-shaped receiving electrodes A10, B11 are provided on one of the stationary side 5 and the movable side 6, whereas two coupling electrodes A12, B14 with a positional phase shift of pi therebetween are provided on the other side, oppositely to the transmitting electrode groups and the receiving electrodes. AC voltages with a time phase shift of pi/2 therebetween are applied respectively to the two transmitting electrode groups A7, B9, and the potential difference between the receiving electrode electrodes A10 and B11 which is varied according to the movement of a carriage is used as an output voltage. The phase differences between the output voltage and the input AC voltages are measured and counted by a circuit 20, thereby detecting the position of the carriage. Thus, even when the amplitude of an output signal is varied with variations in the gap between the movable side and the stationary side, accurate position detection can be achieved independent of the amplitude variations.
