Abstract: PURPOSE:To obtain the film which has uniform physical properties along a width direction and is useful for a magnetic disk, etc., by heat treating a biaxially oriented thermoplastic resin film twice in a normal direction and a reverse direction at each specified temperature and compensating a bowing effect. CONSTITUTION:When the biaxially oriented film composed of a thermoplastic resin (e.g., a polyethylene terephthalate) is heat treated in two steps, the temperature range which is 40 deg.C higher than the glass transition point Tg of the thermoplastic resin and 60 deg.C lower than the melting point Tm of said resin is selected as a foregoing step heat treatment temperature T1 and a heat treatment is performed, the biaxially oriented film being made to run under a tension, then the film is once taken up by winding. Next, the film is rewound and is made to run in a reverse direction to the running direction of the foregoing step, being restrained at its both side edges and the later step heat treatment is performed at the heat treatment temperature T2 ranging from T1+20 deg.C to T1+100 deg.C (provided that T2 is below Tm-8 deg.C), thereby obtaining the desired film.

Abstract: PURPOSE:To make a power unit unnecessary, by interrupting supply of main fuel at the time of idle-up operation of an engine by introducing main bleed air from under a small venturi assembly disposed at the central portion of a large venturi. CONSTITUTION:A small venturi assembly 6 is disposed at the upper central portion of a large venturi 10 of a carburetor 9, and a main nozzle 2 is formed at the small venturi assembly 6. Main bleed air is introduced into a main fuel well 12 from an opening 13c formed at the level of the lower surface of the small venturi assembly 6 near the large venturi 10. With such an arrangement, the amount of air admixed to fuel is reduced by the function of the negative pressure of main bleed air at the time of idle-up operation of the engine when a cooler is set into operation, and fuel is not aspired by the negative pressure as high as that of the idling operation. Further, at the time of high-load operation of the engine, the amount of bleed air is reduced by the function of the negative pressure acted at the large venturi 10, and fuel supplied from the main nozzle is enriched. Therefore, it is unnecessary to provide a power unit specially.
