    摘要： The present invention relates to a microporous polyethylene film for use as battery separator. The microporous polyethylene film according to the present invention is characterized by having a film thickness of 5-40 μm, a porosity of 35-55%, a permeability from 2.5×10−5 to 10.0 10−5 Darcy, a puncture strength of at least 0.10 N/μm at 90° C., a puncture angle of at least 30° at 90° C., and a permeability from 2.0 10−5 to 8.0 10−5 Darcy after shrinking freely at 120° C. for 1 hour. The microporous polyethylene film in accordance with the present invention has very superior puncture strength and thermal stability at high temperature and takes place of less decrease of permeability due to low thermal shrinkage at high temperature, as well as superior permeability. Therefore, it can be usefully applied in a high-capacity, high-power battery to improve thermal stability and long-term stability of the battery.

    摘要： Disclosed is a device for varying valve timing and engaging a cam shaft, in particular for a V-type engine. The device includes a cam shaft on which cams are mounted, a cam shaft pulley for transmitting power from a crank shaft to the cam shaft, a plate for placing the cam shaft pulley in engagement with the cam shaft, and an electromagnet mounted on the cam shaft pulley, the electromagnet being selectively engaged with the plate when electric power is applied thereto. First and second locking pins are provided in the cam shaft for engaging the plate. The locking pins are arranged in relatively eccentric positions and have different radial positions. The engagement between the plate and the cam shaft is achieved selectively by engaging one of the locking pins with the plate. Structure is provided for controlling movement of the locking pins to engage the locking pins with the plate selectively and for applying electric power to the electromagnet according to driving conditions of a vehicle.
