摘要: Provided herein is an ultrasonic motor in which at least fluorocarbon polymer is present on the contact surface of at least either of the rotor of the stator. Since the fluorocarbon polymer provides a smooth contact surface, the ultrasonic motor generates no noise and produces a stable starting torque and holding torque. In addition, it has a long life with a minimum of wear.

摘要: The disclosure is directed to a composite thermal insulator including a Freon gas expanded plastic, and an evacuated powder insulation. The present invention provides a composite thermal insulator light in weight and having a superior heat insulating performance over a long period through replacement of a thick metallic container conventionally used for the evacuated powder insulation and considered indispensable for withstanding a load at one atmospheric pressure and for preventing vacuum leakage, by a film-like plastic container, with activated carbon disposed in it.More specifically, the composite thermal insulator of the present invention includes a Freon gas expanded plastic, a film-like plastic container evacuated to form a vacuum in its interior, and directly contacting and/or covered by the expanded plastic, and activated carbon or inorganic powder containing activated carbon tightly enclosed in the plastic container, light in weight, having a heat conductivity lower than 0.01 kcal/mh.degree.C. and a mechanical strength sufficient for actual use, with almost no variations with time in the heat insulating property.
