Title: Vane rotary compressor
Inventor: UCHIYAMA YOJI
IPC: F04C18/344
Filed: 1992-07-20
Abstract: PURPOSE:To reduce the power consumption by pouring a cooling liquid into a compression chamber, arranging an auxiliary vane having a communication hole between a main vane, and arranging the communication hole at a specific position, as for the constitution in which the vane which can be freely inserted and slipped off from a rotor is arranged. CONSTITUTION:The main part of a vane rotary compressor is constituted of a rotor 1 equipped with a main vane 2 and an auxiliary vane 3, stator 4 which accommodates the rotor 1, and a cooling liquid feeding means 5. In this case, as for the auxiliary vane 3, a communication hole 11 is arranged at the basic edge part close to the rotor 1. The communication hole 11 appears into a compression chamber 8 from the inside of the rotor 1 on the low pressure side close to a suction port 9 side, and is arranged at the position introduced into the rotor 1 on the high pressure side close to an exhaust port 10, and the compression chamber 8 is partitioned even by the auxiliary vane 3 on the high pressure side close to the exhaust port 10. Accordingly, on the high pressure side, the compression chamber 8 is contracted, and the compression pressure is increased, and the counterflow supplied from a gas/liquid separator 15 is reduced.

Title: Biosensor
Inventor: OKUMA KOICHI
IPC: C12Q1/00
Filed: 1988-08-30
Abstract: PURPOSE:To allow the simultaneous detection of plural kinds of chemical components with a small volume of a buffer soln. and plural sensors which are different in reaction living bodies by maintaining a bioreaction part at the pressure lower than the pressure in a buffer soln. reservoir to bleed the buffer soln. to the bioreaction part. CONSTITUTION:The sample soln. poured from an injection port 9 flows through a flow passage 7 in the bioreaction part 1 and flows out through a flow passage 8. The liquid pressure of the soln. flowing in the reaction part 1 is lowered than the liquid pressure in the buffer soln. reservoir 3 by the effect of a pump 5. The buffer soln., therefore, bleeds to the reaction part 1 side by passing the fine pores of an insoluble carrier 2 and maintains the circumference of the enzyme immobilized to the carrier 2 surface to specified pH. The enzyme is maintained at the optimum pH in such a manner and the chemical material generated by reacting with the substrate in the sample is detected by a detector 4. Since the buffer soln. is so bled as to maintain only the surface of the carrier 2 at the optimum pH, the smaller volume of the buffer soln. is necessitated.

Abstract: PROBLEM TO BE SOLVED: To attain heat insulation without useless heating by setting a heating capacity for obtaining the prescribed heat insulating temp. according to the volume of water decided by a boiling mode at the time of a heat insulation mode after boiling. SOLUTION: Only the base heater 8b for heat insulation of base heaters 8a, 8b is so controlled as to maintain the internally contained liquid at a prescribed heat insulation temp. in a low-capacity energizing state and to heat the liquid under the optimum condition meeting the volume of the water after initial boiling or reboiling when a heat insulation treatment is called after the boiling treatment. The information on the volume of the water decided at the time of the boiling mode is commonly used for the volume of the water of this time, by which the control and time for the operation to decide the volume of the water at the time of the heat insulation mode may be omitted.  The heating with the energy lessened in correspondence to the change in the volume of the water is attained in spite of a change in the volume of the water by pouring out of the internally contained liquid if the volume of the water is re-decided when the intenally contained liquid is poured and the optimum heating capacity meeting the volume of the water is set in order to maintain the prescribed heat insulation even in the time of the heat insulation mode.
