    摘要: In an infrared radiation source containing hot-pressed molybdenum disilicide reinforced with silicon carbide whiskers as the illuminant thereof, terminal portions of the illuminant having a protective dense silica film of 5 to 20 .mu.m in thickness formed on the surface thereof which portions are to be heated at a temperature of 400 to 800.degree. C. are either set to have a current density of at most 12 A/mm.sup.2 or disposed in dry air having a relative humidity at 25.degree. C. of at most 30% (absolute humidity: 0.00588). As a result, the low-temperature oxidation phenomenon that would otherwise be developed in the terminal portions of the illuminant is suppressed. Thus, there can be obtained an infrared radiation source containing an illuminant made of molybdenum disilicide reinforced with silicon carbide whiskers and having a long serviceable life span.

    摘要: An advanced liquid cooling system with an advanced cooling characteristic and high reliability, which is small in size and light in weight, is provided. In the liquid cooling system, heating units 2, which are semiconductors, are fixed on a base having high thermal conductivity. A liquid-passage hole 7 in the base 5 allows a liquid refrigerant 6 to pass through. Since the base 5 is made of material with high thermal conductivity, and the liquid-passage hole 7 extends in the vicinity of the heating unit 2 in the base, it is sufficient to transfer the heat of heating unit 2 the liquid refrigerant 6. This enables control of the temperature rise of the heating unit to be maintained low.
