Abstract: The invention provides a type of elastic nut, primary comprising first and second compression slots allowing for compression and connecting strips at the bottom of the retaining nut, with the connecting strips in alternate positions, so that when the retaining nut is used to hold a plug in place on the bolt, and further torque is applied to the retaining nut, the nut is held in place on top of the plug with elastic force, effectively holding the plug in place more tightly.

Abstract: The present invention discloses an adjustable back pad which is formed primarily by a back rack and two back rests. The back rack includes plural slot holes which are left-and-right symmetric and two elastomers. A rear side of each back rest is provided with an elastomer and an elastic element. When assembling the back rack with the back rests, a screw first penetrates a washer and then one slot hole of the back rack, followed by being locked into a lock hole at a center of the elastomer on the back rest. As there are ten elastic buffering pivots between the two back rests and back rack, the ergonomic and breathing back pad of the present invention can completely mitigate a pressure exerted to a lumbar vertebrae or a lower back of a user, thereby soothing fatigue and soreness and providing a most comfortable sitting cushion.

Abstract: An oil-free lubrication centrifugal refrigerant compressor for compressing low-pressure refrigerant into high-pressure refrigerant, includes: a housing; a refrigerant pathway; a compression module; a radial bearing; a first conducting member, collecting troughs and a first exhaust member. Therein, the compression module has a rotating shaft, a compressing member and a driving member; the radial bearing is rotatably disposed around the rotating shaft; the first conducting member conducts lubricating refrigerant fluid to the outer surface of the radial bearing and the inner surface of the rotating shaft so as to provide appropriate lubrication to the radial bearing and the rotating shaft when the driving member drives the rotating shaft to rotate and activate the compressing member to compress low pressure refrigerant into high pressure refrigerant; and the first exhaust member exhausts the lubricating refrigerant fluid, thereby solving the problem of contamination caused by using oil lubricants for compressors as encountered in prior techniques.
