Abstract: PURPOSE:To provide conductivity to titled paper and to decrease curling of the original plate after said plate is discharged from an immersion type desensitization treating machine by adding and using fine conductive fibers in a back coating liquid so that the rear surface is made impermeable with water. CONSTITUTION:For example, carbon fibers, acrylic fibers reduced and deposited with metallic copper in the fibers, and metallic fibers such as stainless steel fibers having 0.1-10mm. cut length and 5-150 denier are used as conductive fibers. The conductive fibers are dispersed in water by using or without using a dispersant and thereafter other components for a back coating layer such as a pigment, binder and waterproofing agent are added to the soln. to prepare a coating liquid for the back coating layer. Said liquid is so coated on the rear surface that the fibers are uniformly dispersed over the entire coated surface and that the fibers contact with each other like network. Substantial conductivity is obtd. after the coating. The water permeability of the base paper is thus suppressed and the curling of the original paper in the stage of an immersion type desensitization treatment is decreased.

Filed: 1980-02-28
Abstract: PURPOSE: To provide a typewriter which sets right and left margin positions at a control part through a continuous single action under such mechanism that a recording head scans at the depression of a push-button on a margin set key and reading a distance to the right and left margin positions from a home position.  
     CONSTITUTION: In a typewriter where right and left margin positions can be independently set, a head moves until it detected right and left margin positions starting from a home position at the depression of a single margin set key and the value of a counter at time of detection is memorized at a control part. The counter moves to right from a home position as 0 which movement means "plus" and moves to left which signifies "minus". The pulses generated every fixed rotary angle of a motor has only to be counted. As a result, the right and left margins are set at positions 1, 3, and then printing is performed. Where a shift to the fifth line is carried out, only the left margin has to be changed to a position 2 and the right margin is automatically changed to a position 4.

IPC: G03G15/08
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To obtain a developer with which a good image can be formed without causing filming, splashing of a toner and image fog by specifying the shape of toner particles containing a positive electrification controlling agent, negative electrification agent, etc. SOLUTION: This developer contains toner particles in which at least two kinds of electrification controlling agents of a positive electrification controlling agent and a negative electrification controlling agent. The toner particles have 7 to 10μm 50% average diameter and 0.93 to 1.0 average circularity. Toner particles having <=0.93 circularity are included by 7 to 20% and the 10% average diameter in the distribution of particle size in accumulated number is 45 to 80% of the 50% average particle size. If the circularity is <0.93, the toner shows high aggregation degree to decrease the fluidity, which causes lack of the developing amt. of the toner on a photoreceptor and decreases the image density. Moreover, the cleaning property deteriorates and triboelectrification with the carrier is not enough to cause insufficient electrification.  As a result, this causes filming of the toner on a drum, splashing of the toner in a copying machine and increase in image fog.
