    摘要： 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.

    摘要： Disclosed is a biaxially drawn polyhexamethylene adipamide film having a relative viscosity of at least 3.2 as measured at 25.degree. C. in aqueous 96% H.sub.2 SO.sub.4, a degree of crystallinity of from 35% to 45%, a birefringence (.DELTA.n) of not more than 0.006, as determined at any point in its entire area, and an initial modulus of elasticity in tension of at least 230 kg/mm.sup.2 as determined in ay direction across substantially its entire area. The film may be produced by a process wherein molten polyhexamethylene adipamide is extruded through a circular die gap and the tubular extrudate is brought in sliding contact with the outer periphery of an inside mandrel, thereby to be cooled, which process is characterized in that polyhexamethylene adipamide having a relative viscosity of from 3.3 to 5.0, as measured at 25.degree.
