Title:
HEAT SHIELDING CASE
Document Type and Number:
Japanese Patent JPS60191316
Kind Code:
A
Abstract:
PURPOSE:To improve the heat insulating effect of a heat shielding case by securing a close combination at a lower part of the shielding case between a bottom part of an approximately flat plate structure and a cover part of a semidouble structure or a fully double structure and therefore keeping the warmed air within said shielding case. CONSTITUTION:A bottom part 11 of a heat shielding case which has an approximately flat plate structure includes a support part 11a for an IC1 containing an on-chip thermostatic chamber, a hollow part 11b into which an end of a cover part 12 for the main body of said shielding case is fitted and a hole 11c through which a pin 1a of the IC1 is put. The cover 12 of a semidouble space or fully double space structure is adhered to the part 11 at a lower part Z. Thus the 1st space 13 storing the IC1 and the 2nd space 14 are formed by both parts 11 and 12. In such constitution, the warmed air can be kept within the shielding case. This improves the heat insulating effect of said shielding case.
