Title: Air-fuel ratio control device for gas combustion device
Inventor: TSURUTA TORU
IPC: F23N5/02
Filed: 1994-04-07
Abstract: PURPOSE:To enable a positive ignition and a flame transfer to be carried out always under a proper air-fuel ratio in a gas combustion device even if a temperature in a combustion chamber is high or low. CONSTITUTION:A temperature within a combustion chamber is measured by a temperature sensor 17 and if the measured temperature is lower than a reference temperature (for example, 30 deg.C), an ignition and a flame transfer are carried at an air-fuel ratio in which a degree of gas rich in respect to a rational air-fuel ratio is set to be high and in turn if the measured temperature is lower than the reference temperature, the ignition and flame transfer are carried out at an air-fuel ratio in which a degree of gas rich is decreased. It amy also be assumed that a temperature of the combustion chamber is indirectly estimated in reference to a temperature TH of hot water remained in a hot water feeding-out pipe or an elapsing time elapsed from a flame extinguishing and the like.

IPC: H01L21/3065
Filed: 1989-04-13
Abstract: PURPOSE:To form a flat surface of a coating layer by a method wherein a recess generated on the coating layer is filled with first resin and after solidifying it with second resin solved by solvent which does not solve the first resin applied on the recess, the first resin, the second resin and the coating layer are etched at the same etching rate. CONSTITUTION:A recess 41 generated on the surface of a layer 4 for coating a semiconductor substrate is filled with first resin 6, then second resin 7 solved by such solvent that does not solve the first resin 6 is applied on it, and after solidification the first resin 6, the second resin 7 and the coating layer 4 are etched back by using etching method indicating the same etching rate to them. Use of resin insoluble to the second layer solvent as the first layer resin prevents the shape of two kinds of resin layers from being deformed due to melting of the first layer resin at the time of applying the second layer resin so that the surface of the second resin layer 7 can be completely flattened. Thus a flat surface of the coating layer can be obtained.
