  • Patent number: 7452908
    Abstract: This invention relates to compounds which are represented by the general formula [I] [in which A stands for a group of the following formula [ao] or [b0] Ar1, Ar2 and Ar3 stand for optionally substituted phenyl; k stands for 0 or 1; m, n and s stand for 0, 1 or 2; R1 stands for hydrogen or optionally substituted lower alkyl; R2, R3, R4 and R5 either stand for hydrogen or optionally substituted lower alkyl, or R2 and R3, or R4 and R5 together stand for trimethylene and the like; R60 stands for hydrogen, alkyl, or the like; R61 and R71 either stand for alkyl and the like, or together stand for trimethylene and the like; X stands for carbonyl or methylene; Y stands for nitrogen or methine; and Q? stands for anion], and the like. The compounds of the invention exhibit selective antagonism to muscarinic M3 receptors, and therefore are useful as safe and effective agents showing little side effect, for treating diseases of the respiratory, urinary and digestive systems.

  • Patent number: 7381032
    Abstract: In a hermetic compressor in a freezing refrigerating system or an air-conditioning system such as a refrigerator or a showcase, a construction is disclosed for intending to provide a low-noise hermetic compressor by effectively attenuating a pressure pulsation having occurred in a compression chamber with a suction muffler. By this construction, since a muffler cover 20 has a planar simple shape, the deformation upon molding becomes little and it can come into fully close contact with a muffler main body 19. Therefore, the pressure pulsation hardly leaks through the connecting portion between the muffler main body 19 and the muffler cover 20. The full silencing effect that the suction muffler 18 has is obtained and thereby noise can be reduced more effectively.

  • Patent number: 7244108
    Abstract: This invention relates to a hermetic compressor used on a refrigerant cycle such as a refrigerator, and discloses a low noise compressor designed to attenuate a resonance sound in a compression chamber and intake pressure pulsing more operatively at a position adjacent to their sources, which intake pressure pulsing occurs at an intake valve port. In the compressor, a resonance space 38 is provided adjacent to the intake valve port 29 that is closer in distance to a noise source. As a result, noise can be reduced more operatively than muffling functions of an intake muffler 31 do. In addition, although acoustic characteristics of the intake muffler 31 amplify noises having specific frequencies, such noises can be attenuated before being amplified.

  • Patent number: 7021425
    Abstract: A sealed electric compressor for use in, for example, an electric refrigerator, generates a little noise and can feed any moving part of its compressing element with refrigerator lubricant. An oil pickup tube is joined by insertion to the lowermost end of a crank shaft and includes a first centrifugal pumping portion and a second centrifugal pumping portion provided continuously and arranged at a smaller angle than that of the first centrifugal pumping portion. The second centrifugal pumping portion arranged at a smaller angle can spin in a pool of the refrigerator lubricant.

  • Patent number: 6957951
    Abstract: In a hermetic compressor for use on an air-conditioning unit as well as a refrigerating unit such as a refrigerator and a showcase, there is disclosed a constitution designed to provide a silently operated hermetic compressor that has an intake muffler readily assembled thereon. The hermetic compressor including a substantially disk-like elastic member disposed between the intake muffler at an outlet thereof and a cylinder head is provided, in which an outlet orifice of the intake muffler constantly remains pressed against an intake valve port through a gasket.
