  • Publication number: 20130011219
    Abstract: In an embodiment, a booklet conveying device includes: a pair of conveying units; a positioning unit; a pressing unit; and a conveying-force changing unit. The pair of conveying units convey a booklet made of a stack of folded sheets, and change a distance therebetween. The positioning unit positions the booklet by making a leading-end portion of the booklet abut thereto. The pressing unit presses the booklet positioned by the positioning unit onto one of the conveying units in order to fix. The conveying-force changing unit changes the conveying force exerted by the conveying units.

  • Publication number: 20120085118
    Abstract: A refrigerant compressor that enhances compressor efficiency by both reducing an amplitude of pressure pulsations and reducing pressure losses in a discharge muffler space into which is discharged a refrigerant compressed at a compression unit. A low-stage discharge muffler space is formed in the shape of a ring around a drive shaft. In the low-stage discharge muffler space, a discharge port rear guide is provided in the proximity of a discharge port through which is discharged the refrigerant compressed by a low-stage compression unit. The discharge port rear guide is provided at a flow path in one direction out of two flow paths from the discharge port to a communication port in different directions around the drive shaft, and prevents the refrigerant from flowing in that direction, thereby causing the refrigerant to circulate in a forward direction in the ring-shaped discharge muffler space.

    Abstract: A device that enhances compressor efficiency by reducing pressure losses in a discharge muffler space into which is discharged a refrigerant compressed by a compression unit. A low-stage discharge muffler space is formed in the shape of a ring around a drive shaft. In the low-stage discharge muffler space, a communication port flow guide is provided so as to cover a predetermined area of an opening of a communication port from a side of a flow path in a reverse direction out of two flow paths in different directions around the drive shaft from a discharge port through which is discharged the refrigerant compressed by a low-stage compression unit to the communication port through which the refrigerant flows out. The communication port flow guide transforms a direction of a flow into a direction of a connecting flow path.
