Abstract: The pipe heater manufacturing process comprises a vacuum making process A for introducing a stainless steel pipe into a furnace and evacuating the inside of the furnace, for example, to a pressure of 0.5 Torr, a pipe end sealing process B for brazing and sealing plugs 3 to both ends of the pipe under vacuum and brazing, a process C for forming a lower insulating layer by repeating several times the steps of screen printing an insulating glass material and baking it in a state in which the two ends of the pipe are sealed, and similar formation process D of a heat generating layer and formation process E of an upper insulating layer. With this method, baking in an oxygen-free state inside the pipe makes it possible to obtain the oxidation-free clean state without high-temperature corrosion on the inside of the pipe having the fluid to be heated flowing therein and to manufacture a pipe heater in which a heating response was improved by forming thin heating layer and insulating layer.

Abstract: A cooling apparatus (1) has a compressor (2), a condenser (3), an expansion valve (5), an evaporator (6) and an electric valve (10), all connected to each other in this order by a piping line to form a refrigeration circuit. The apparatus further has a heating section (11) and a bypass (12), and a thermosensitive tube (13) of the expansion valve is disposed between the heating section (11) and the electric valve (10) so that temperature of a refrigerant having left this section is detected before entering this valve (10). The refrigerant remains as a gas-liquid mixture until it leaves the evaporator (6) such that temperature of the refrigerant is uniform within the evaporator and equal to the saturation vapor temperature of this refrigerant, and therefore fluctuation in the refrigerant temperature is diminished.

Abstract: Provided is a power cycle test apparatus that eliminates the need to measure a thermal resistance in a power cycle test and that pursues power saving in the evaluation of IGBT reliability by exactly applying a required thermal stress through the automatic adjustment of a stress current. The power cycle test apparatus performs a power cycle test for an IGBT to be tested by applying a thermal stress to the IGBT to be tested through the intermittent application of a stress current thereto. The apparatus applies the stress current to the IGBT to be tested and thereafter applies a current for measurement to the IGBT to be tested to measure a collector-emitter voltage of the IGBT to be tested. The apparatus further obtains a junction temperature of the IGBT to be tested from the measured collector-emitter voltage and a temperature coefficient of the IGBT to be tested.
