Title: Method for aging gas sensor
IPC: G01N27/12
Filed: 1992-03-13
Abstract: PURPOSE:To eliminate an interfering gas so as to improve the certainty of aging at the time of aging a gas sensor by using an atmospheric gas from which small amounts of interfering gases are removed through activated carbon and, at the same time, to facilitate oxygen adsorption by making the partial pressure of the atmospheric oxygen used for the aging higher than the partial pressure of the atmosphere. CONSTITUTION:A pump 5 sucks air and introduces the sucked air to an adsorption tower 2 through a flowmeter 6. The tower 2 is provided with an activated carbon layer 1 through which small amounts of interfering gases contained in the air are removed. The cleaned air is introduced to an aging box 4 and used as the atmospheric gas of a gas sensor 3. When the partial pressure of atmospheric oxygen used for aging is made higher than that of oxygen contained in the atmosphere, the resistance-value restoring time of the sensor 3 becomes shorter as the partial pressure becomes higher. In other words, adsorption of oxygen to a metallic oxide semiconductor is facilitated and the semiconductor can be more quickly hardened by aging.

Title: Heat pump regeneration device
Inventor: YABUMOTO OSAMU
IPC: F24F5/00
Filed: 1988-03-07
Abstract: PURPOSE:To improve a performance factor (evaporation power/compression power) of a heat pump, by arranging two types or more of regeneration materials whose melting points are different from each other so that a temperature gradient along the flowing direction of a heat transfer medium of an outside load in a regenerating device may be approximately the same with a temperature gradient of refrigerant in an evaporator and/or a condenser. CONSTITUTION:For example, in a case using mixed refrigerant where the evaporation temperature of refrigerant inside an evaporator 8 varies from 2 deg.C to 7 deg.C from an inlet side to an outlet side, the ports a-b of a three-way change over valve 10 are communicated with each other during heat regeneration, and a pump 9 starts it operation, thereby circulating cooled water in the direction expressed by solid lines. After the evaporator 8 has cooled the cooled water returned from a regeneration device 1 from 10 deg.C to 5 deg.C, the cooled water is supplied to the regeneration device 1 so as to solidify a regeneration material 11 consecutively starting with a low melting point side (left side), while the temperature of cooled water rises to 10 deg.C at a high melting point side (right side) and returns to the evaporator 8 again. During irradiating operation, the ports a-c of the three way change over valve 10 are communicated with each other and a pump 13 starts its operation, thereby circulating the cooled water in the direction as described so that the cooled water at 12 deg.C may be led to the regeneration device 1 from the high melting point side ot the high melting point side, allowing the regeneration material 11 to absorb its melting heat from the cooled water toward the low melting point side. In this manner, the water cooled down to 7 deg.C is sent to a cooling load 14 again.
