Title: Developing roller for wet type developing device of electrophotography
Inventor: MACHIDA HAJIME
IPC: G03D5/06
Filed: 1979-06-28
Abstract: PURPOSE:To obtain good squeeze effect and images of good quality by using the developing roller which contains 10-90% short fibers of <=50 denier and <=5mm.  length in rubber, synthetic resin or metals. CONSTITUTION:10-90% short fibers of, for example, nylon, ''Tetoron '' or silk are kneaded in rubber, synthetic resin or the melt of metals and the mixture is molded to roller form, after which it is ground to be finished to a roller. Since the fibers are not ground, the fibers protruded from the surface of the roller. Here, the size of the short fibers is regulated to <=50 denier and <=5mm. length . If this roll is used as a developing roller, it will not remove toner images 13, unlike conventional rubber rollers. In addition, no gaps are produced around the toner images 13 and therefore the developing solution is evenly supplied, squeeze effect is good and the images of good quality may be obtained.

Filed: 1981-05-29
Abstract: PURPOSE:To efficiently carry out the cooling of an electric motor, by cooling both the upper coil end and lower coil end units of the motor in this way splitting the refrigerant gas discharged out of the scroll compressor. CONSTITUTION:The high pressure gas discarged out of a discharge opening 12 upon compression at a scroll compressor unit 2 flows around an electric motor unit 3 past a refrigerant gas passage 17 and a connection pipe 8 through. This gas partially flows downward along an electric motor unit 3, cooling a lower coil end 14 and the rest of gas flows into an upper coil end 15 while turning around the motor 3, and finally it is discharged out of the closed receptacle after having the upper coil end 15 cooled.

Abstract: PURPOSE:To eliminate the defective transfer that arises at the rear end of transfer paper by changing the magnitude of the voltage or current to be impressed on a corona discharging means in such a way that the charge quantity of the corona discharge at the rear end of the transfer paper is made smaller than the charge quantity of the corona discharge at the part except the rear end of the transfer paper. CONSTITUTION:A selector switch SW is kept connected to a terminal A in the stage of starting a copying operation and the high output current from a power source 32 for transfer is impressed on a corona wire 30. On the other hand, the switch SW is connected to a terminal B by the signal from a control circuit 33 at the timing at which transfer paper P detaches from guiding plates 6, 6, and the low output current from a power source 31 for transfer is impressed on the wire 30. More specifically, the current impressed on the wire 30 in accordance with the rear end of the paper P and the part except the rear end thereof is controlled, by which the charge quantity of the corona discharge applied on the rear end of the paper P is made smaller than the charge quantity of the corona discharge applied on the part except the rear end. As a result, the charge quantity applied over the entire surface of the paper p is consequently maintained at the charge quantity enough to obtain satisfactorily stable transfer efficiency and the charge density on the paper P is made uniform over the entire surface of the paper P.
