Abstract: A piston type compressor includes a housing forming a cylinder bore. A drive shaft is supported by the housing. A cam plate is coupled to the drive shaft and is rotated by the rotation of the drive shaft. A piston is accommodated in the cylinder bore and is coupled to the cam plate. The rotation of the cam plate is converted into the reciprocating movement of the piston. In accordance with the reciprocating movement of the piston, gas is introduced into the cylinder bore, is compressed and is discharged from the cylinder bore. Compression reactive force is generated in compressing the gas by the piston, is transmitted to the housing through a compression reactive force transmission path and is received by the housing. A vibration damping member is made of a predetermined vibration damping alloy and is placed at least one location along the compression reactive force transmission path.

Abstract: A filter 42 comprises a cylindrical filter body 45 which is disposed in a suction passage 41, a lid portion 47 which closes an opening 45b positioned in a downstream side of the suction passage 41 in the filter body 45, communication holes 48 which penetrate through the filter body 45 and communicate the inside of the filter body 45 with the outside thereof, and filter elements 49, 50 which are disposed downstream of the communication holes 48 and the lid portion 47, in the filter body 45; wherein a gap between an outer circumferential surface 45c of the filter body 45 and an inner circumferential surface 45a of the suction passage 41 is closed upstream of the communication holes 48.

Abstract: An upper die supporting section for supporting an upper die is provided to a lower portion of a holder body 7, a pressing section for pressing the upper die against the upper die supporting section is provided to a lower portion of an upper die clamp 11 supported to the holder body 7 in a rocking manner with a vicinity of a center in a vertical direction being as a supporting point. A locking member which freely locks into a drop-proof groove provided to the upper die is provided to a lower portion of the upper die clamp 11, and it is biased towards the upper die supporting section. Clamping force applying means 13 for pressing an upper portion of the upper die clamp 11 so as to apply a clamping force for clamping the upper die using the upper die clamp 11 is provided.

Abstract: A disk cartridge, which is compact, which requires a small number of parts, and which is easily assembled, is provided. The disk cartridge of the present invention comprises an upper case and a lower case. Each of the upper case and the lower case is formed to be substantially circular. The upper case and the lower case define a disk-accommodating section when the lower case and the lower case overlap with each other. The disk cartridge is opened/closed by rotating the upper case relative to the lower case about a base point of a movable section which is provided for the upper case and/or the lower case. An information-recording disk is accommodated and removed in a state in which the disk cartridge is open.

Abstract: A cartridge and a drive unit that drives a cartridge and has an insertion opening into which the cartridge is inserted are provided. The drive unit includes a shutter which opens and closes the insertion opening, and a mechanism for locking a close state of the shutter so as to prohibit a different type of cartridge and the cartridge not facing a predetermined direction from proceeding to an inside of the drive unit, and for unlocking the close state so as to allow the shutter to proceed to the inside of the drive unit. The cartridge includes a unlock member that unlocks the close state of the shutter in cooperation with the mechanism.

Abstract: A damping device is arranged in a gas passage in a compressor for damping compression waves transmitted from suction valves. The damping device includes a damper arranged in a damper hole provided in a pipe fitting of the compressor housing. The damper has concentric inner and outer cylindrical walls, and end wall closing ends of the inner and outer cylindrical walls, and radial holes at the end of the inner cylindrical wall. The outer cylindrical wall is arranged in the damper hole and the inner cylindrical wall is fitted in the fitting hole leading to the suction chamber. A gas passage is formed by an inner passage portion, radial holes, an inter-wall passage portion, a radial passage portion at the end opposite to radial holes, and an outer passage portion between the outer cylindrical wall and the side cylindrical wall of the damper hole.

Abstract: The objects of the present invention are to improve the fan efficiency by the decrease of the shaft power of a fan and/or the increase of the pressure rise owing to a fan impeller, which are accomplished by the rational control of the energy based on the tangential velocity of the prerotation flow generating at ‘the region ahead of an impeller’ inside the suction pipe of a fan, and to reduce fan noise by the improvement of air flow at the portion in close vicinity to an impeller inside the suction pipe. The present invention is related to a by-pass unit (5) disposed upstream an impeller to control the energy generated by the air flowing into the impeller (1), comprising a specific region of a suction pipe (2) as a part of the by-pass unit (5), an air chamber (3), through which the air is able to pass, forming a closed spatial region outside the suction pipe (2), and communicating passages (4) for connecting the closed spatial region to the suction pipe (2).

Abstract: A reciprocating piston type compressor for compressing refrigerant gas for an automobile air conditioning system is improved to protect itself without protective control by a computer. The compressor detects the temperature of a part of the compressor in which the temperature increases to higher than a predetermined critical temperature when the compressor malfunctions, and changes a displacement control valve to reduce the displacement of the compressor when the detected temperature is higher than the predetermined critical temperature.

Abstract: An upper tool clamp is provided that is supported by a holder body arranged on an upper table of a press brake, so that the upper tool clamp can be oscillated between a clamped state and an unclamped state. A pressing member is mounted on a lower portion of the upper tool clamp in order to press an upper tool on an upper tool support portion which is mounted on a lower portion of the holder body. Further, an engage projection is formed on the upper tool clamp and freely engageable with a drop prevention groove which is formed on the upper tool. In addition, a first clamp/unclamp device and a second clamp/unclamp device are mounted on the holder body, respectively.
