摘要： Provided is a method for producing a tube, comprising:
extruding a melt-fabricable fluororesin from a mold of an extruder into a form of a tube,
leading the extruded melt-fabricable fluororesin to a cooling device to cool the extruded melt-fabricable fluororesin, and
winding a resulting cooled tube onto a winding reel using a winding device,
wherein a gas is fed from a head end of the tube wound onto the winding reel into a hollow of the tube,
the gas in the hollow is allowed to pass through a gas-introducing entrance of the mold and then through a gas-discharging hole of the mold to discharge the gas outside, thereby allowing the gas to flow along the hollow, and
an internal pressure of the hollow is kept higher than atmospheric pressure and lower than 0.5 kgf/cm 2 .

摘要： The present invention addresses the problem of providing a bimorph-type piezoelectric film that is less susceptible to the influence of pyroelectric noise resulting from temperature changes, and that makes it possible to provide a pressure-sensitive sensor or the like. The present invention provides a bimorph-type piezoelectric film comprising a first pyroelectric film having piezoelectric anisotropy in an in-plane direction, and a second pyroelectric film having piezoelectric anisotropy in an in-plane direction, the first pyroelectric film and the second pyroelectric film being disposed in such a manner that their surfaces on which electric charges of the same polarity are generated by a temperature increase are each outward-facing.
