    摘要: A rubber composition for tire treads is disclosed which is designed to exhibit high resistance to skidding on wet, icy and snowy roads. A selected rubber blend of styrene-butadiene rubber and natural rubber and/or polyisoprene rubber is combined with a selected carbon black of specified specific surface areas and also with a selected softener of specified viscosity-gravity constants. The styrene-butadiene rubber consists essentially of two styrene-butadiene block copolymers each having varied styrene and vinyl contents and a specified transition temperature width, one block having a higher glass transition temperature than the other.

    摘要: A heat pump system usable as an air-conditioning apparatus, a refrigerant apparatus, or a temperature-conditioning apparatus, having a heat capacity detection mechanism for detecting a signal indicative of a ratio of or a difference between the total heat-emitting capacity of the condenser and the total heat-absorbing capacity of the evaporator, and an energy-supplying mechanism for exerting energy onto the refrigerant, thereby compensating for insufficient total hear-absorbing capacity, especially in the cooling mode when condensation capacity increases due to, for example, a cold or wind environment.

    摘要: An engine-driven heat pump apparatus having a refrigerant circulation line which includes at least one inside heat-exchanger for exchanging heat between the air in a room and the refrigerant, and a pressure-controlling device for substantially maintaining the pressure on the high pressure side of the refrigerant circulation line by, for example, narrowing the opening of the expansion valve(s), decreasing the volume of air passing through the inside heat-exchanger(s), recirculating the air passing through the inside heat-exchanger(s), lowering the heat efficiency of the engine when the required quantity of radiated heat from the inside heat-exchanger(s) in use is increased, e.g., when the number of inside heat-exchanger(s) in use is increased, thereby maintaining or increasing heating power in the heating mode, irrespective of the number of inside heat-exchangers in use.

    摘要: An engine-driven heat pump apparatus having a refrigerant circulation line which includes a pressure-measuring device for measuring the pressure in the refrigerant circulation line downstream of a compressor and upstream of an expansion valve, and an exhaust heat controller for controlling the exhaust heat from the engine based on the pressure by, for example, changing the heat efficiency of the engine, e.g., by controlling at least one of (a) the ignition timing of the engine, (b) the opening and closing timing of an intake port valve and an exhaust port valve, and (c) the opening of a fuel gas-controlling valve, so as to efficiently increase heating power during heating operation at low temperatures, without increasing engine noise or shortening the life of the engine.
