    摘要: A valve plate includes a plurality of suction holes and a plurality of suction reed valves for opening and closing them. At least two of these suction reed valves have different natural frequencies. In this configuration, a natural frequency of one reed valve is larger. Therefore, even when an operation frequency is changed to a higher frequency, the compressor can suck a refrigerant gas into a cylinder efficiently without occurring delayed closing and reduction of a lift amount. Thus, refrigerating capacity and compression efficiency can be increased.

    摘要: To provide a two-cycle combustion engine of a simplified structure with the number of component parts reduced, which is effective to suppress a blow-off of the air/fuel mixture and is excellent in acceleration, the two-cycle combustion engine includes scavenging passages (13, 14) communicating between a combustion chamber (1a) and a crank chamber (2a), an air/furl mixture passage (11) for introducing an air/fuel mixture (EM) from a fuel supply device (3) to the crank chamber (2a), and a branch passage (10A) ramified off from the air/fuel mixture passage (11) for supplying a lean air/fuel mixture (TM) into the scavenging passages (14). During an intake stroke, the lean air/fuel mixture (TM) from the branch passage (10A) is introduced into the scavenging passages (14) and the air/fuel mixture (EM) is introduced from the air/fuel mixture passage (11) into the crank chamber (2a). During a scavenging stroke, the lean air/fuel mixture (TM) is supplied from the scavenging passages (14) into the combustion chamber (2a) prior to introduction of the air/fuel mixture (EM).

    摘要: Liquid packs 34 provided with liquid leading members 42 are stored in a container case 31 that is constituted by fitting a case main body portion 32 and a lid case 33 in fitting portions 27 and 28, support portions 13, which positions the liquid leading members 42 so as to be opposed to liquid introducing members 71 attached to a cartridge inserting portion 13, are provided on a front surface 32a of the container case 31, the fitting portions 27 and 28 are arranged in a state in which the fitting portions 27 and 28 traverses the support portions 43, and space portions 29 and 30 having a gap larger than a gap formed in the fitting portions 27 and 28 are formed near the support portions 43 in the fitting portions 27 and 28. In this way, liquid flowing through the fitting portions 27 and 28 due to the capillarity is retained by the space portions 29 and 30 and never flows to the fitting portions 27 and 28 further extending from the space portions 29 and 30.

    摘要: Herein disclosed is an electric blind of the type, in which a traverse rod drive motor, a tilt rod drive motor and their drive transmitting means are arranged at one end side of a casing frame so that the casing frame can be easily cut at the other end side without removing those motors and the drive transmitting means to leave a new casing from of a desired length. The traverse rod and the tilt rod can be cut together with the casing frame to improve the workability of the electric blind. This blind has its slats offset from the center line of the casing frame so that a shield cover can be extended to below the casing frame to prevent the light from breaking therethrough. In this blind, moreover, the positions of the clamping portions of brackets for supporting the two sides of the casing frame can be adjusted independently of one another so that the blind can be mounted on the wall or the like without any difficulty.

    摘要: An improved rotary machine such as centrifugal type compressor adapted to rotate under high load of the type including a plurality of impellers fixedly mounted (shrinkage-fit) on a main shaft. To effectively inhibit the rotor from vibrating due to loosened fitting of the impellers onto the main shaft the improvement consists of each of the impellers being provided with a sleeve portion which is made integral with the impeller. The sleeve portion is located at a position removed from the main part of the impeller along the axial direction of the main shaft with the position being determined in accordance with the theory of strength of materials in such a manner that displacement of the impeller in the radial direction due to centrifugal force resulting from rotation of the rotary machine has no effect on determination of the position of the sleeve portion, wherein the sleeve portion is shrink fit onto the main shaft of the impellers.
