A double-sided needle assembly includes an insert needle for inserting into a vessel; an afflux needle for supplying pharmaceutical liquid in an injector to the insert needle; and a luer member. The member connects the insert needle with the afflux needle through a space defined between the ends of the needles in the member, and holds the insert and afflux needles to fit to the syringe of the injector under pressure. The confirmation of the insertion of the insert needle into the vessel is accomplished by observing the space of the luer member.

A reagent feeder which can to be used in both a finger-push system and a slide system by only attaching and detaching a simple auxiliary component to and from a case body depending on the state of operation or a preference of the operator. The feeder includes a case body, a sphere discharge port and a discharge device, so as to discharge a sphere one by one by pushing down the discharge device. The discharge device is provided with an operation lever which extends out of the case body and can be pushed down by a finger. A slide cover surrounding an outer periphery of the case body is attached to the case body in such a way that it can be moved freely in a vertical direction and can be detached from the case body. The slide cover is engaged with the operation lever of the discharge device so that it can be moved integrally with the discharge device.

A radiation-shielded injector comprises a cylinder of radiation shielding material having a cutout, a transparent radiation shielding plate being fitted to the cutout, a through-hole being provided at the closed end of the cylinder, a winged finger holding member being fixed to the cylinder, a cap having a hole for the passage through of a plunger being detachably attached, and a syringe-type body encapsulated with radioactive material, the cap being attached to the free end of the cylinder whereby the body is fixedly caught between the closed end of the cylinder and the cap. The infected is characterized by forming a built-up portion like a bank of radiation shielding material on the cutout periphery of the cylinder, the peripheral lateral side of the transparent plate being thereby covered with the thickness of the built-up portion. The radiation-shielded injector thus designed can minimize leakage of radiation and effectively protect the operator from radiation exposure.

In a refrigerator, an intermediate heat exchanger as an evaporator in the refrigeration cycle 11 in which a flammable refrigerant is sealed is provided inside of a heat insulating material. A heat transferring device is provided between the intermediate heat exchanger and a heat exchanger for cooling. At the time of stop and occurrence of the refrigerant leakage, the refrigerant inside of the intermediate heat exchanger is recovered into the condenser or into the refrigerant recovery cylinder so that even if the refrigerant leaks out, a leaked amount of the refrigerant into the refrigerator is reduced.

Disclosed is an air conditioner and, in particular, an air conditioner which is capable of blowing out warm air in heating mode. In the air conditioner of this invention, the condenser is thermally separated into an air-upstream-side and an air-downstream-side heat exchanger, and the heat exchange capacity of the air-downstream-side heat exchanger is adjusted, so that, under preset operating conditions, the entire refrigerant in the air-downstream-side heat exchanger can be kept in the superheated-gas phase, thus making it possible to blow out warm air having a temperature higher than the condensation temperature. Further, the refrigerant temperature at the outlet of the air-downstream-side heat exchanger is measured by a temperature sensor, and the revolving speed of the compressor, the revolving speed of the fan, etc., is so controlled that the temperature measured is kept at a level higher than the condensation temperature. Thus, under all operating conditions, the entire refrigerant in the air-downstream-side heat exchanger can be kept in the superheated gas phase, thereby making it possible to blow out warm air having a temperature higher than the condensation temperature.

A control system for a compressor motor used with an air conditioning unit is disclosed. A current for generating a non-rotating magnetic field is supplied to the compressor motor to preheat a compressor. A current for generating a rotating magnetic field is also supplied to the compressor motor together with the current for generating a non-rotating magnetic field to heat the compressor. The heat pump using this control system is thus capable of transmitting sufficient heat energy immediately after start of the operation of the heat pump.
