摘要： PURPOSE:To smooth the falling of snow in a tank by self-weight of the snow by providing a constriction to a snow throwing port of the upper part of the snow-melting tank equipped with a heater to the bottom thereof to make small a throwing area, and preventing thrown snow from adhering to the internal wall of the tank. CONSTITUTION:A constriction 8 is provided to the upper part of circumferential wall of a snow-melting tank 2, and the area of a snow-throwing port makes smaller than the inside area of the snow-melting tank 2. Snow is thrown into the tank 2 through a grating 9 provided to an upper opening of the tank 2, thrown snow is heated by a heater 5 on the bottom thereof to change it into water, and snow into the tank 2 is subsequently lowered by self-weight of the snow. After the snow in the tank is melted, it is detected by a sensor 7, and power to the heater 5 is disconnected. Melt water is drained. According to the constitution, snow is not made to adhere to the inside wall of the tank, and the falling of snow can be made smoothly.

摘要： PURPOSE:To get a mean electrical power load by a method wherein a heating tower is operated to collect heat from surrounding air, the heat is accumulated in a heat accumulating tank acting as a low temperature heat source, the accumulated heat in the heat accumulation tank is applied as a heat source, and a heat pump is operated in a low electrical power load time range to get a high temperature heat source. CONSTITUTION:A heating tower with a cooling capability of 20 horsepower and having antifreeze (-10 deg.C) is operated for about 10 hours at a daytime with a surrounding air temperature of about 0 deg.C to 5 deg.C to collect heat with a temperature of antifreeze of -5 deg.C and a total quantity of heat of 500Mcal and store it in a heat collecting tank 5. Then, a heat pump 7 is operated with the antifreeze in the heat accumulating tank 5 being applied as a heat source at a nighttime of a low electrical power load time range to get hot water having a temperature of 50 deg.C. A coefficient of performance of the heat pump 7 is 2.4. This hot water is used as a part of a mean heating load of 70Mcal/h as a heating operation at 8:00 to 18:00 of a high electrical power load time range (10 hours) with a temperature difference of 10 deg.C and an efficiency of 0.85. Then, it is possible to get a mean electrical power load.

摘要： PROBLEM TO BE SOLVED: To provide a small turning torque, in a head for tightening a circular plate- shaped cover having small height, in the initial stage of cover tightening by means of contact pressure with the cover and provide a sufficiently large torque in the final stage of cover tightening. SOLUTION: In a head 10, one end 12a of a mounting shaft 12 is mounted to a chuck at the forward end of a drive axis of an electric motor, and a supporting seat 16 and a contact member 18 are provided on the other end 12b of the shaft 12 successively from the side of the shaft 12. The member 18 is made from natural rubber or silicone rubber and formed into a circular plate-shape. While the member 18 is being turned about the shaft 12, a contact surface 18a of the member 18 is brought into contact with the top surface of the circular plate-shaped cover. Since a surface contact is provided between the contact surface 18a and the top surface of the cover, turning torque given to the cover can be adjusted by corresponding to the contact pressure between the surface 18a and the top surface of the cover. As a result, by using a simple mechanism for lifting or lowering the head 10, problems can be solved and hence construction of device for attaching and detaching a cover using the head 10 can be simplified, resulting in reduced cost.

摘要： PROBLEM TO BE SOLVED: To provide a fire proof FRP sash excellent in fire proof safety without any breakage when the fire proof test of a B class fire proof door is performed and excellent in lightweight and heat insulation. SOLUTION: A sash bar such as a stile, a push edge and a frame fitted vertically and horizontally to glass plates 2, 3 integrally forms a first reinforcing fiber layer 4 comprising the woven fabric of a glass fiber during drawing forming of FRP and a second reinforcing fiber layer 5 provided continuously on the first reinforcing fiber layer 4 on the surface. When the fire proof test of a B class fire proof door is performed, the first reinforcing fiber layer 4 and the second reinforcing fiber layer 5 are cooperated to prevent breakage due to carbonization deterioration of FRP.
