Title: Temperature compensation circuit
Inventor: ISHIHARA TSUTOMU
IPC: G05F1/56
Filed: 1984-11-12
Abstract: PURPOSE:To make a circuit suitable to MLS circuit integration by installing a detection circuit and a thermo-sensitive diffusion resistance having a positive temperature coefficient more than resistances connected between an input terminal at the inversion side and common terminal and between sources of an FET and a detection circuit. CONSTITUTION:A bridge circuit 100 is constituted in such a way that its drain is excited by the output of the FET30 of source follower arrangement, which is connected to an electric power source terminal 13. With this constitution the bridge circuit 100 and the thermo-sensitive diffusion resistance 12 go to the load of the source follower, and the load of an arithmetic amplifier 20 includes only the gate capacity of the FET30, whereby only the capacity load lies without a resistance load. Consequently the electric power consumption of the amplifier 20 can be significantly reduced. Moreover the FET30 simply bears a current equal to a load current, and the electric power consumption can be substantially reduced in terms of the overall circuit. Thus an extremely useful temperature compensation circuit suitable to the MOS integration can be realized.

Title: Low-temperature storage room
Inventor: MASE TOKUTARO
IPC: A23B7/12
Filed: 1989-09-14
Abstract: PURPOSE:To slow down the speed of variations in gas composition in a storage chamber, control deterioration in the quality of living foodstuffs and preserve them for a long period of time by allowing ethylene gas evolved from the foodstuffs stored in the storage chamber to be gradually absorbed by a gas absorbing member disposed at a part of an inner case good in heat conduction and discharging a portion of the absorbed ethylene gas into a space. CONSTITUTION:Each of top and bottom, front and rear, and right and left walls 3A to 3F is cooled by cold air, and the interior of each of storage chambers 10 is cooled indirectly by heat transfer from each wall surface. On the other hand, since living agricultural products stored in the storage chamber 10 respire and since the storage chamber 10 is closed, air in the closed storage chamber is only convected naturally, and gas composition in the storage chamber 10 varies due to ethylene gas evolved by the respiration of the agricultural products. However, the ethylene gas evolved is gradually absorbed by a gas absorbing member 20 disposed on each of the right and left side walls 3D to 3F, and a portion of the absorbed ethylene gas passes through holes 25 to be gradually discharged into a cold-air circulation space 11. Therefore, the density of the ethylene gas in the storage chamber 10, which gradually increases, is reduced, and the speed of variations in the gas composition can be slowed down, whereby the period of preservation of the agricultural products can be prolonged.

Title: Moxibustion device
Inventor: TERANISHI AKIHIKO
IPC: A61H39/06
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a moxibustion device capable of being used for a local lesion and excellent in handleability by providing a heat generating body with small heat capacitance having a heating part to be brought into contact with the lesion and a pulse generating circuit supplying pulse current to the heat generating body. SOLUTION: When a switch 26 is turned on at first, a power source part 24 supplies D.C. current to a transistor 18 and the pulse generating circuit 20 generates a pulse with a frequency set in a setting equipment 22. Thus, the switching of the transistor 18 is executed, the pulse current of the frequency being the same as that of the pulse is electrically energized in the heat generating body 10 and heating is periodically repeated. Since the heat generating body 10 has small heat capacitance, its temp. is immediately lowered to the normal one at the time of nonconductivity. Thus, the front surface of the heating part is put on the lesion, especially a pressure point, so that it is periodically repeated that the lesion is heated or made to be normal temp. in accordance with the pulse.  Therefore, the moxibution effect is increased by centralizing heat to one point without causing stimulous practice by simply heating by fixed temp.
