IPC: H01J29/26
Filed: 1988-11-14
Abstract: PURPOSE: To provide high light transmissivity and a uniform thickness formed to stop an electron by containing a zinc sulfide layer and two silicon dioxide layers sandwiching this, in a barrier of a flat surface. CONSTITUTION: Two kinds of phosphors 2 and 4 are composed of powder of the respective phosphors 2 and 4 separated from each other by a barrier 3 of a flat surface, and are a superimposed layer, and are stuck on a transparent support body 1 of this screen, and the barrier 3 of the flat surface has a first silicon dioxide layer 31, a zinc sulfide layer 32 and a second silicon dioxide layer 33, and the zinc sulfide layer 32 is contained between the two silicon dioxide layers 31 and 33. A thickness of the silicon dioxide layers 31 and 33 is actually independent of operating voltage, and is selected so as to enhance light transmissivity of the zinc sulfide layer 32 having a high refractive index. Therefore, the total refractive index of the barrier layer 3 is reduced, and light transmissivity is enhanced thereby.

IPC: B41J29/36
Filed: 1987-11-13
Abstract: PURPOSE:To shorten correction time and reduce consumption of a ribbon, by correcting characters through grouping the characters for each identical paper feed position. CONSTITUTION:At the time of printing, character data on characters printed on a printing medium MA by a printing means MB is stored into a storage means MC. At the time of correcting characters, the paper feed position of the characters in a predetermined range specified by a correction instructing means MD is first detected by a paper feed position detecting means MF, and the characters are grouped for each identical paper feed position by a grouping means MG. Next, a correction order instructing means MH causes a correcting means ME to correct the characters in the predetermined range, for each group of the characters. The correcting means ME reads the characters in the predetermined range from the storage means MC, and corrects the characters at each identical paper feed position. By this, correction time is shortened, and a correction ribbon is prevented from being consumed at interruption in a continuous correcting operation.

Title: Developer for electrostatic latent image
Inventor: HAYASHI MAYUMI
IPC: G03G9/08
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To stabilize developing characteristics of a developer even when plastic deformation of a polyolefin is caused by introducing a proper amt. of carbon black having a specified oil supply amt. as a conductive fine particles to be added to a coating resin for a carrier. SOLUTION: This developer consists of a carrier comprising magnetic particles coated with a polyolefin and a toner containing a binder resin and a coloring agent. To the coating resin of the carrier, carbon black having 50-300ml/100g oil supply amt. is added by 5-50wt.%. If the oil supply amt. of carbon black is <=50ml/100g, dispersibility of the carbon black in the coating resin decreases, which makes difficult to stably control the volume specific resistance of the carrier. If the oil supply amt. is >=300ml/100g, good dispersibility is obtd. but the structure of the carbon black is easily broken, which render the volume resistance of the carrier unstable for long-term use.
