Abstract: PROBLEM TO BE SOLVED: To economically and easily perform sufficient internal sweeping on the transmission side of fibers by supplying a part of an impermeable dehydrated gas formed on the transmission side of the fibers in a module as countercurrent sweeping gas. SOLUTION: Supply gas 12 containing steam is supplied to the pores of the hollow fibers 22 of a gas separation module 10 under the pressure applied to the surface of a first tube sheet 14, and the steam transmits through the fibers 22 to be issued from an outlet 20 of the module 10, but dehydrated gas remains in the pores of the fibers 22. Staple fibers 24 piercing a second tube sheet 16 under pressure return a part of the dehydrated gas to the transmission side of the fibers 22 and countercurrent sweeping action is applied to the dehydrated gas on the transmission side of the fibers 22 to discharge the dehydrated gas from an outlet 18. As mentioned above, sweeping is performed by product gas.  Therefore, the sweep gas dilutes the concn. of transmitted water on the transmission side and the steam partial pressure on the transmission side is lowered to develop the high transmission speed of water.

Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To miniaturize a switching power supply circuit and to improve power conversion efficiency by switching between a twice voltage rectification operation and quadruple voltage rectification operation from an AC input voltage level. SOLUTION: When an AC input voltage VAC which is equal to or more than 150V is supplied, a voltage value divided by resistors R1 and R2 becomes equal to or more than a specific value and a zener diode ZD of a relay drive circuit 10 turns on. Therefore, a base potential of a transistor(Tr Q5x become equal to or more than a specific value, the emitter current of TrQ5x does not flow to a relay drive part RD1 , and a switch S1 is turned off. Then, smoothing capacitors Ci3 -Ci4 are charged, thus obtaining a rectification smoothing voltage 2Ei which is two times VAC. When VAC which is equal to or less than 150V is supplied, ZD does not turn on, thus turning on TrQ3 since based current flows via the resistor R3 and hence obtaining a rectification smoothing voltage 4Ei at the smoothing capacitors Ci3 and Ci4 .

Abstract: PURPOSE:To obtain the high-quality thin film of a cubic boron nitride usable as a semiconductor by supplying active N2 near to a substrate at the time of forming the thin film of the cubic boron nitride on the substrate by a molecular beam epitaxy method. CONSTITUTION:The active N2 activated by a microwave discharge is supplied as a nitrogen source near to the substrate to form the thin film by reaction near the substrate in the method for forming the thin film of the cubic boron nitride on the substrate by the molecular beam epitaxy method. The N2 having the high activity and the boron are brought into reaction according to the above-mentioned method and, therefore, the high-quality thin film of the c-BN is synthesized. Since the film formation is executed after evacuation to a super high vacuum, the contamination by the gases remaining in a chamber, for example, H2O or hydrocarbon, etc., is averted. Since the boron is liable to react with oxygen, an important requirement is to decrease the gases remaining in the chamber.
