  • Patent number: 9952370
    Abstract: A method for manufacturing a stretched film for producing a long-length stretched film by stretching a long-length resin film while being conveyed so as to pass through an oven in a state in which the end portions of the resin film are held by first and second grippers, wherein the oven has a preliminary heating zone, a stretching zone, a thermal fixing zone, and a reheating zone in this order from an upstream side; the stretching zone includes a specific zone having a temperature gradient capable of setting a temperature of an end portion on a second gripper side is higher than a temperature of an end portion on a first gripper side by 5° C. or higher and 15° C. or lower; and the reheating zone has a temperature capable of heating the resin film to a temperature of Tg+5° C. or higher and Tg+20° C. or lower.

  • Patent number: 6335572
    Abstract: A portable heat transfer apparatus including a combustion device, a thermoelectric convertor for receiving the heat of the combustion device at its high temperature side, transferring the heat from its low temperature side to a heat exchanger, and generating electric power depending on the temperature difference between the high temperature side and low temperature side. A heat medium forced circulating device is driven by the power generated from the thermoelectric converter for transferring heat medium to the heat exchanger. Also provided is a heat releasing device for circulating and releasing the heat medium exchanged of heat in the heat exchanger. Therefore, the heat exchanger can be heated through the thermoelectric converter while heating the thermoelectric converter with the combustion device, and by heating with the heat exchanger. The temperature difference between the high temperature side and low temperature side of the thermoelectric converter can be obtained rationally and sufficiently.
