A polycrystalline silicon film 37 containing an n type impurity is deposited on the whole surface. The n type impurity is diffused through the residual polycrystalline silicon film 36 from a wiring 39 containing the n type impurity through heat treatment.

Title: Air conditioner
Inventor: YOSHITSUBAKI AKIFUMI
IPC: F25B41/00
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To reduce vibration and noise by fixing an elastic body to the way of a refrigerant piping and fixing the elastic body to a nearby structure thereby suppressing contact of the piping thereto or vibration of piping due to fluctuation of piping layout. SOLUTION: A refrigerant delivery piping 2 and a fixing metal 3 are fixed by an elastic body 1 and the fixing metal 3 is fixed to a base 4 secured with a vibration source, i.e., a compressor 5. Such a vibrationproof structure functions to correct relative positional shift of piping due to fluctuation of piping layout automatically thus preventing generation of abnormal noise due to contact of piping. Since the refrigerant delivery piping having high vibration level is fixed through an elastic body to the base, the elastic body absorbs vibration energy to reduce vibration of piping.
