Abstract: PURPOSE:To obtain a building panel with regular patterns on the surface by pushing a rubber belt having rugged patterns on the surface moving at the same velocity as the moving velocity of the building panel after water is sprayed on a coating layer, providing the rugged patterns on the coating layer, and subsequently applying an overcoating material. CONSTITUTION:While the building panel 1 is moved up with the surface, the coating material is applied on the building panel surface to provide the coating layer on which water is sprayed, and later, the rubber belt 71 with the rugged patterns is pressed on the surface moving with nearly the same velosity as the moving velocity of the building panel 1 to provide the rugged patterns on the coating layer. Later, the overcoating material is applied on the coating layer. Hence, on the building panel the desired patterns are regularly provided. Also, since water is sprayed before the rubber belt is pushed, the sticking of the coating material on the surface of the rubber belt can become difficult. And, since the rubber belt is moved with nearly the same velocity as the moving velocity of the building panel, there is no shift between the coating layer and the rubber belt and the transferred patterns from the rugged patterns provided on the rubber belt are provided on the coating layer as they are.

IPC: F24F11/02
Filed: 1990-11-21
Abstract: PURPOSE:To make it possible to delay the start of freezing and reduce the amount of ice by lowering the frequency of a compressor by a specified value when a refrigerant discharge temperature from the compressor reaches the preset upper limit during heating operation and raising the frequency of the compressor by a specified value when it falls below the lower limit and repeating this procedure. CONSTITUTION:An attempt is made to decide if a refrigerant discharge temperature from a compressor 1 exceeds a specified value, say, 102 deg.C. If it exceeds 102 deg.C, the frequency of the compressor 1 is lowered by a smaller value than the maximum frequency, say, 20Hz. After the operation is monitored for three minutes under the same operating condition, an attempt is made to decide if the defrosting requirements are satisfied. When the decision result does not exceed 12 deg.C, the decision is made for whether or not the refrigerant discharge temperature falls below 98 deg.C. If it is decided that the temperature is 98 deg.C or below, it will be necessary to raise the operation frequency of the compressor 1 by 20Hz in order to increase the heating capacity.
