Abstract: PURPOSE:To obtain a thin film conductive layer having a firm bonding force to an AlN substrate by a method wherein the thin film conductive layer consisting of Al is formed on the AlN substrate. CONSTITUTION:A hot-pressed compact consisting of AlN powder, a sintered body using a sintering assistant, such as Y2O3, CaO and the like, and the like can be used for an AlN substrate 1 in a circuit board. In case an Al thin film conductive layer 2 is formed on the substrate 1, the surface of the substrate 1 is sufficiently cleaned by a wet cleaning method, a reverse sputtering method or the like before the formation. Provided that, in case the wet cleaning method is used, it is necessary to use a neutral surface-active agent because the substrate 1 is unstable to a strong acid and a strong alkali. After the substrate 1 is cleaned, the layer 2 is formed using a normal thin film formation method, such as a deposition method, a sputtering method, a CVD method and the like. Moreover, after a desired pattern is formed of a resist on the layer 2, a normal etching is performed. Thereby, the circuit board with a desired wiring pattern is obtained.

Abstract: PROBLEM TO BE SOLVED: To secure a communication space for cold air in a simple structure. SOLUTION: An outlet duct 71 for blowing cold air toward a ceiling-plane 2a is mounted at an upper end portion of a partition 63 partitioning a refrigerating chamber 2 and a cooling chamber 9. A cold air guide member 81 is mounted at a position ahead of the outlet duct 71. The cold air guide member 81 is suspended from a ceiling-plane 2a for a predetermined size and is so provided as to extend from an outlet port 75 toward a side face on the opposite side thereof along the entire width of the ceiling-plane 2a, and the front surface of the cold air guide member 81 is formed into a slope 84 whose inner part is inclined downward. Since the cold air guide member 81 interferes, foodstuffs (x) can only be packed to a position under the member 81, and, accordingly, a communication space for cold air is secured on the rear side of the cold air guide member 81. Cold air blown from the outlet port 75 of the outlet duct 71 passes through the above-mentioned communication space to reach the entire width of the ceiling-plane 2a and is sucked into the side of the cooling chamber 9 after passing through spaces among the foodstuffs (x). Thus, the cold air is favorably circulated and fed.
