摘要:
Fixed scrolls 4, 5 are supported so to be movable axially relative to an orbiting scroll 6, so that a proper space is kept between wraps 4a, 5a and 6a to avoid an excessive load in the contacting area. Further, an end portion of an outer curve of the wrap 6a of the orbiting scroll 6 is formed to come close to or coincide to an outer edge of a panel 6f of the orbiting scroll 6 and an Oldham's coupling is accommodated in a concave groove 6e formed on an outer circumference surface of the panel 6f, so that the size of the scroll compressor is reduced.

A displacement type fluid machine in which a displacer and a cylinder are disposed between end plates, a space is formed by an inner wall surface of the cylinder and an outer wall surface of the displacer when the center of the displacer is put on the center of the cylinder, and a plurality of spaces is formed when the positional relationship between the displacer and the cylinder is for a gyration, is restrained from deterioration of the efficiency. One of the end plates and a vane protruding inwardly from the inside surface of the cylinder are fixed to each other so as to restrain the deformation of the vane and decrease the leakage of a working fluid due to the deformation.

A scroll type compressor comprises a stationary scroll and a rotary scroll which is assembled with the stationary scroll so as to define a closed space, the outer surface of the rotary scroll 22 is formed thereon with a tin compound film containing a tin compound and having a thickness of 50 .mu.m. Such a coating film is never peeled off from a member even after long time operation, and is excellent in sealability and conformability, in the displacement type compressor.
摘要:
An automatic urine disposal device has a urine collecting pad, vacuum pump, and urine tank. In the urine collecting pad, the top sheet comes in contact with the wearer's skin, the hydrophilic sheet is disposed on the bottom of the top sheet, and the urine absorbent sheet is disposed at the bottom. When discharged urine flows in the top sheet, the hydrophilic sheet widely diffuses urine to saturate its entire surface and then becomes non-breathable. As the vacuum pump vacuums the air from the urine tank, urine is directed from a urine drainage port of the urine collecting pad via a urine drainage tube to the urine tank which is a sealed container.

摘要:
In a method of correcting a distorted pipe end to an original substantially true circular cross-section, external loads are applied to the outer peripheral surface of the pipe adjacent to the end thereof to forcibly deform the pipe end to the substantially true circular cross-section. The external loads are maintained to keep this substantially true circular cross-sectional shape while an internal pressure is applied to the inner peripheral surface of the pipe end until a circumferential stress produced in the pipe reaches an amount which exceeds the yield stress of the pipe to give a radial permanent deformation to the pipe for thereby producing a circumferentially uniformly distributed residual stress in the pipe.

摘要:
A liquid cooling system for cooling a high heat generating body, such as a semiconductor element or the like, of the type used in an electronic apparatus that is small and thin in size, or in a personal computer equipped with such a structure therein. The system has a pump of the reciprocal movement type, a heat receiving jacket, a heat radiation pipe, and a connector pipe for connecting those parts with one another so as to form a closed loop filled with a cooling liquid. In the system, &Dgr;Vs is equal to or greater than &Dgr;Vp, wherein the inner volume change when the pump emits pulsation therefrom is &Dgr;Vp, the pressure caused by the volume change is P, and the volume change due to the pressure P that occurs in flow passage of the cooling liquid &Dgr;Vp other than within the pump, is &Dgr;Vs.
