Filed: 1993-09-21
Abstract: PURPOSE:To protect a heat insulating film from etching when a semiconductor thin film is etched even if the semiconductor thin film is overetched. CONSTITUTION:A substrate 2 has a hollow part 1. A heat insulating film 3 is so formed as to cover the hollow part 1 and to have its circumferential part supported by the substrate 2. A foundation protective film 4 having a required pattern is formed on the heat insulating film 3 and, further, a semiconductor thin film 5 for a semiconductor element and having a required pattern is formed in the surface region of the foundation protective film 4.

As the heat insulating film 3 is not etched, the mechanical strength of the heat insulating film 3 is not deteriorated when the hollow part 1 is formed for thermal isolation. Therefore, the breakage, etc., of the heat insulating film 3 which can occur with a conventional constitution can be avoided, so that the manufacturing yield can be improved.

Abstract: PROBLEM TO BE SOLVED: To protect an electrical dust precipitator and a blower from damage caused by the overheat in a fire in a tunnel by locating a liquid spraying means and a mist removing means in descending order in the upstream of the electrical dust precipitator in a ventilator equipped with the electrical dust precipitator in the flow path. SOLUTION: A liquid spraying means 11 is installed in the upstream of an electrical dust precipitator 5 and a mist removing means 12 such as a mist eliminator is installed between the liquid spraying means 11 and the electrical dust precipitator 5. Therefore, since the air temperature is reduced by spraying cooled liquid into hot air containing dust from the liquid spraying means 11, the damage caused by overheating the electrodes of the electrical dust precipitator 5 and a blower 3 can be prevented. Then, the sparking caused by the mist entering the electrical dust precipitator 5 and also the reducing of the dust collection efficiency of the electrical dust precipitator 5 can be prevented since the sprayed mist is removed by the mist removing means 12 before entering the electrical dust precipitator 5.
