Abstract: A hermetic compressor has low noise and high refrigerating capacity. This compressor includes a position adjustement mechanism, a communication cut-off mechanism, a flow path change-over mechanism, etc., in order to dispose an open end portion, inside of a sealed container, of a suction flow path through which a cylinder of a compressor communicates with the inside of the sealed container on a specified plane, so that it coincides with the positions of the nodes of a resonance mode occuring inside the sealed container.

Abstract: PROBLEM TO BE SOLVED: To provide a control device for a linear compressor capable of stabilizing the behavior of its piston and precluding increase in noise and vibrations, resulting from collision and/or lowering of the reliability. SOLUTION: The piston behavior is stabilized by furnishing the arrangement with an instability-sensing means to sense directly or indirectly that the piston behavior has become unstable and to emit instability-sensing signal and an unstableness, avoiding means to operate in conformity to the given signal.

Abstract: PROBLEM TO BE SOLVED: To improve productivity and reliability of a linear motor. SOLUTION: A smooth cylindrical shape can be formed easily by engaging a thin plate 9 having higher magnetic permeability among a plurality of projected portions 11 provided on a fixing belt 10 which may be curved, and by forming an outer yoke 8 in which the fixing belt 10 is formed cylindrically so that the thin plate 9 is laminated almost radially. Accordingly, productivity can be improved and moreover reliability can also be improved by preventing contact with a movable magnet.

Abstract: PROBLEM TO BE SOLVED: To enhance productivity and reliability, by easily forming a smooth cylindrical form of a linear motor. SOLUTION: The productivity can be enhanced because the smooth cylindrical form can be formed, and also the reliability can be enhanced by preventing contact with a mobile magnet, by equipping the linear motor with a cylindrical outer yoke 8 where a thin plate 9 high in permeability is bent repeatedly for stacking circumferentially.

Abstract: PROBLEM TO BE SOLVED: To miniaturize a vibration type compressor as well as preventing reduction of piston position detecting accuracy. SOLUTION: A fixing part 19a of a displacement detector 19 is disposed on the end part of the reverse compression chamber side of a cylinder 15, and a movable core part 19b is disposed on an outer peripheral part of a piston 16. Reduction of the position detecting accuracy caused by the influence of assembly accuracy can be prevented, and also the compressor can be miniaturized.

Abstract: PROBLEM TO BE SOLVED: To provide a slide member for a compressor, pump, etc., in this invention, having high reliability by attaining low friction in a slide location and improving abrasion resistance in the case a small amount of oil is supplied or even under a condition of oil free. SOLUTION: A compression mechanism, a refrigerant, and refrigerator oil are housed in a closed vessel, this slide member is characterized by consisting of compound material blending nickel powder and carbon powder by 1 to 30 wt.% in total relating to titanium boride ceramics powder of 70 to 99 wt.% in at least one slide material in the compression mechanism. In addition to abrasion resistance provided in titanium boride ceramics itself, by self lubrication with boride, a compressor and a pump are obtained in high reliability and high efficiency even in the case oil supply is in a poor condition.

Abstract: PROBLEM TO BE SOLVED: To provide a vibration type compressor preventing the occurrence of a fatigue failure and having high reliability by reducing the stress occurring on the arms of an elastic body when a piston is reciprocated and the elastic body repeats displacement in the piston axial direction. SOLUTION: When a piston is reciprocated and an elastic body repeats displacement in the piston axial direction, the elastic body is reciprocated with its arms 20a, 20b, 20c warped. The arms 20a, 20b, 20c form vortexes partially having fine portions and large portions with the arm widths smoothly changed. Fine portions are deformed relatively largely, the stress at the fine portions is relatively increased, and the stress at other stress concentrated portions can be reduced. When the piston is reciprocated and the elastic body repeats displacement in the piston axial direction, the stress occurring on the arms 20a, 20b, 20c can be reduced, thereby a vibration type compressor preventing the occurrence of a fatigue failure and having high reliability can be provided.
