摘要： PURPOSE:To perform a superior returning of discharged oil of a freezer to a compressor by a method wherein CFC-R23 is used as refrigerant for freezing cycle at a low temperature side of two-refrigerant freezer and refrigerant sucked into a compressor is controlled to be a wet state. CONSTITUTION:Refrigerant vapor of high temperature and high pressure from a high temperature compressor 1 flows into a condenser 2, condensed, liquefied there and its pressure is reduced by a high temperature side expansion valve 3. Refrigerant of low temperature side is cooled by a heat exchanger 4 and the former refrigerant evaporates by itself and then the refrigerant is sucked into the high temperature side compressor 1. Refrigerant R23 is used as a refrigerant for low temperature side freezing cycle, the refrigerant of high temperature and high pressure discharged from the low temperature side compressor 5 is cooled by the heat exchanger 4, condensed and liquefied there. The liquid refrigerant is reduced in its pressure by the low temperature side expansion valve 12, flows into the evaporator 7 to cool the cooled item, thereafter the refrigerant passes through a wetness sensor 13 and then the refrigerant is sucked into a compressor 1. A low temperature expansion valve controller 14 takes an output signal from the wetness sensor 13 and a degree of opening of the low temperature side expansion valve 12 is adjusted in such a way as the wetness becomes a predetermined wetness. Since a sucked refrigerant is adjusted to become a wet state, a returning characteristics of the oil of the freezer is improved and then a poor lubrication of the compressor for a low temperature freezing cycle is prevented.

摘要： PURPOSE:To enable accurate control of temperature and humidity in a sample chamber whenever illuminators are lit or not, by installing a temperature and humidity control point of a cultivation space in the sample chamber for growing a plant on the lee outside the sample chamber in a vessel. CONSTITUTION:In an air circuit in a vessel, air is sucked from a blower suction chamber 2 by a circulating blower 5, passed through a blower blowoff chamber 3 and subjected to temperature and humidity conditioning with a cooling dehumidifier 6, a heater 7 and a humidifier 8 and the air at the conditioned temperature and humidity is then blown off from an outlet 4' for blowing the air into the vessel provided in temperature and humidity conditioning chamber 4 into the sample chamber 1. On the other hand, light energy with an illuminance required for growth of a plant is irradiated from illuminators 10 provided in sample chamber 1. The temperature distribution in lighting the illuminators at this time is such that a position at the same temperature as that of the central part in the sample chamber is present in the blower suction chamber 2 where is on the lee in the vessel. In a controlling part 11, sensed values of temperature and humidity inputted from a temperature and humidity sensor 9 are compared with the preset values of temperature and humidity. If both values are different, commands are sent to the circulating blower 5, cooling dehumidifier 6, heater 7 and humidifier 8 for making the sensed values in agreement with the set values of the temperature and humidity. Thereby, the temperature and humidity of the air blown into the sample chamber 1 are controlled.

摘要： PURPOSE:To prevent not only the adhesion of scale to a humidifier and a sensor but also the freezing of a drain pipe by perfectly performing drainage, by providing a water supply and drain solenoid valve performing opening and closing operations at the time of the stoppage of an apparatus and at the time of a low temp. below 0 deg.C in a test chamber. CONSTITUTION:When an apparatus is operated under a temp. and humidity condition, water supply solenoid valves 13-1, 14-1 receive the supply of a current to open and to cut off drain solenoid valves 13-2, 14-2 and water is supplied to a humidifier 5 and a wet bulb sensor pot 6. When the apparatus is stopped, the water supply and drain solenoid valves are automatically set in reverse operation and the water in the humidifier 5 and wet bulb sensor pot 6 is discharged. At the time of a low temp. below 0 deg.C in a test chamber 1, the water supply solenoid valve 14-1 to the wet bulb sensor pot 6 is cut off and the drain solenoid valve 14-2 receives the supply of a current to open and to discharge the water out of the wet bulb sensor pot 6 and conduit 15.

摘要： PURPOSE:To execute a humidity control without being interrupted by replenishing with supplementary water to a humidifier after preheating it in advance by a preheating means provided on a high heat source part of a refrigerating cycle. CONSTITUTION:Exhaust gas of high temperature and high pressure, which is compressed by a compressor 6 flows into a heat exchanger 17 from an exhaust pipe 11, is heat- exchanged with water replenished from a supplementary water feed pipe 18 and heats water. On the other hand, the exhaust gas is cooled and flows into a condenser 9, is heat-exchanged with air by forced draft, is cooled and liquefied. A liquefied refrigerant liquid is led to an expansion valve 8 from a pipe 10, is pressure-reduced and expanded by the valve 8, and thereafter, flows into an evaporating chamber 3 of a thermo- hygrostat chamber 1, and cools and dehumidifies circulating indoor air by an air blower 2. Subsequently, refrigerant gas of a low temperature, which loses its cooling performance is absorbed into the compressor 6 again and is compressed. In this case, the humidifying operation is executed by replenishing supplementary water preheated in advance by the heat exchanger 17 to a hmidifier 12, together with an operation of an electric does not ocur heater 13, therfore, the interruption of generation of vapor by replenishment.

摘要： PURPOSE:To prevent a tray from getting out of position and to flatten the upside of an IC on a warped soft tray by a method wherein a mechanism which clamps an IC tray is provided. CONSTITUTION:A clamping pawl 7 which clamps a tray 5 is kept in a clamping state when a handler is in operation to transfer an IC from the tray 5 or a handler is out of operation. The clamping pawl 7 is kept in a clamping state by the spring force of a spring 10. By this process, the tray 5 can be prevented from getting out of position. Furthermore, the tray 5 on a tray lifting board can be controlled in level so as to be pressed against the clamping pawl 7 by the ascending motion of a lifting motor and a photoelectrical switch sensor 11. By this setup, the upside of an IC on the tray 5 such as a warped soft tray or a broad soft tray liable to warp can be flattened by correction.

摘要： PURPOSE:To perform the characteristic inspection and the lead outward-appearance inspection of an IC within the same process by a method wherein an IC lead inspection mechanism which is provided with a function to perform the lead outward-appearance inspection of the IC is installed inside a handler main body. CONSTITUTION:An IC lead inspection mechanism 2 which is provided with a function to perform the lead outward-appearance inspection of an IC is provided inside a handler main holy 1. For example, a supply container in which uninspected ICs have been loaded and stacked is set in a container feed part 5; the ICs in the container at the uppermost part are conveyed one by one, and their characteristic inspection is performed in test sockets 18, 19. Then, the ICs whose characteristic inspection has been finished are conveyed up to the position of an IC lead inspection part 27; the IC lead outward-appearance inspection is performed by means of the IC lead inspection part 27. The ICs whose inspection has been finished are sucked by means of a head 13 in a collection robot 12. According to the judgment of whether the result of the characteristic inspection is good or not and whether the result of the lead outward-appearance inspection in the lead inspection mechanism 2 is good or not, the ICs are sorted and collected in housing containers 7 to 9.
