The outlet is unblocked when the compressor is inactive. The compressor may be activated and deactivated in accordance with the atmospheric temperature.

Abstract: A heater unit comprises a casing through which air flows in one direction from an inlet to outlets. A heater core is disposed within the casing for heating air passing therethrough. An air mix door is also disposed within the casing and has a pivotal end about which it is swingable for controlling the amount of air heated by the heater core and the amount of unheated air bypassing the same. In the above arrangement, air is difficult to pass through the heater core at a place adjacently behind the pivotal end of the air mix door whith respect to the direction of air flow. A tank portion of the heater core is disposed in the place adjacently behind the pivotal end of the air mix door with respect to the direction of air flow.

Abstract: A transistor protection device in accordance with the present invention includes a base platform consisting of a flat aluminum board for fixing a power transistor with small screws or the like. A supporting plate is placed at a prescribed distance from the base platform, and the base platform and the supporting plate are separated by means of solid heat conducting rods and hollow rods through which are inserted conductors. The heat conducting rods are arranged to have their top ends to make contact with the bottom surface of the power transistor which is the portion of maximum heat production in the power transistor, in order to conduct the heat generated to the outside of the power transistor. Because of the better radiation capability which takes place in relatively thin rods, there are installed a plurality of the heat conducting rods.

Abstract: First and second outlets direct conditioned air into a vehicular passenger compartment. When one of the outlets is blocked, the other outlet is unblocked. A control arrangement ensures that the temperature of the output air is the same regardless of which outlet is unblocked. This is achieved by adjusting the position of an air mix door, which determines the extent to which air is heated before being delivered as conditioned air, in accordance with which outlet is unblocked.

Abstract: A liquid colorant for ABS resins is described, comprising 100 parts by weight of a pigment or dye and 25 to 2,000 parts by weight of a liquid polyester, and having a viscosity of 1,500 poises or less at room temperature. This liquid polyester is prepared mainly from an aliphatic dicarboxylic acid and a dihydric alcohol, and usually has a viscosity of 10 to 1,500 poises at room temperture.
