Abstract: A scroll type fluid displacement apparatus includes a pair of scrolls having a circular end plate and a spiral element extending from an axial end surface of the circular end plate. An involute slit is formed in an involute plate. The spiral elements are inserted into the involute slit so that the involute plate and axial end plate adjoin one another. The involute slit includes an inner edge, an outer edge and an extreme line joining the inner edge with the outer edge. A first radial gap is formed between the extreme line and radial ends of the spiral element. The first radial gap is greater than a second radial gap formed between the inner and outer edges of the radial ends of the spiral element. First portions of the inner edge and outer edge are prevented from contacting the end of a spiral element even if the end of the spiral element thermally expands more than other portions of the spiral element.

Abstract: A printer control system for controlling a print characteristic of a printer for printing a print pixel signal synchronized to horizontal lines of an image. The print pixel signal has an arbitrary horizontal resolution and includes white print pixel signals representing white pixels of the image and black print pixel signals representing black pixels of the image.

Abstract: In an image printer performing multi-color printing, two magnetic poles having the same polarity are provided adjacent to each other in a position facing the printing body of the second developing agent holding body provided in the second developing unit, and development is performed under a condition satisfying the following formulas;B1.ltoreq.1100,1000.ltoreq.B2.ltoreq.1200,-300.ltoreq.B1-B2.ltoreq.0,F.apprxeq.0where B1 (gauss) is a magnetic flux density on the surface of the developing agent holding body of one magnetic pole of the magnetic poles arranged in the downstream side of the transmitting direction of the developing agent, and B2 (gauss) is a magnetic flux density on the surface of the developing agent holding body of the other magnetic pole of the magnetic poles arranged in the upstream side of the transmitting direction of the developing agent, and F (gf) is a rubbing force to the printing body of the magnetic brush in the second developing unit.

Abstract: An imaging apparatus such that residual toner on a transfer/conveyer mechanism such as a transfer belt and an intermediate transfer material is effectively removable. High-tension voltage opposite in magnetic polarity (plus) to the charged toner and a photosensitive drum is applied to a discharger 15 provided ahead of a drive member 12 for driving a transfer belt 6. The residual toner on the transfer belt 6 is removed by a brush 21, and the residual foreign substances come in contact with the photosensitive drum 1 and move onto the photosensitive drum 1 before a printing operation is started. The foreign substances are then removed by a photosensitive drum cleaner.

Abstract: A developing apparatus in which a stationary multipole permanent magnet is placed in a sleeve and in which development is performed by bringing a developer, which contains at least carrier and toner particles and is held on the periphery of a sleeve by use of the magnetic force of the multipole permanent magnet, into contact with a photo-conductive body owing to the rotation of the sleeve. For securing image density and for preventing the deposition of carrier onto the photo-conductive body, two magnetic pieces, each of which is arranged lengthwise in the direction of the axis thereof and which have the same polarity, are placed in a region in the multipole permanent magnet which faces the photo-conductive body in such a manner as to adjoin in the circumferential direction of said permanent magnet. This results in generation of the distribution of a magnetic field which has two peaks of magnetic force.

Abstract: A first-side toner image 25 is formed on a photo receptor 2 and transferred on a dielectric belt 19. A second-side toner image 18 is formed on the photo receptor 2. The two toner images 25 and 18 are simultaneously transferred on both sides of a print paper 26, and fixed thereon by paired heat rolls 30 and 31.

Abstract: A refrigerant compressor includes a compressor housing defining a chamber in which successive strokes of intake, compression, and discharge of a refrigerant gas are repeatedly performed. The chamber is divided into a compression chamber and a discharge chamber by a valve plate. A discharge hole links the compression chamber to the discharge chamber. The valve plate includes an end surface which faces the discharge chamber. A discharge valve regulates a flow of the refrigerant gas from the compression chamber to the discharge chamber. A valve retainer limits the bending movement of the discharge valve in the direction in which the refrigerant gas exits the discharge hole. The valve retainer is secured to an axial end surface of the valve plate together with the discharge valve by a fixing bolt. The discharge valve bends as it opens and closes the discharge hole. The valve plate includes an annular groove formed at the end surface thereof.
