Title: Production of pigment dispersion for electrophotographic sensitive body
Inventor: SAITO ATSUSHI
IPC: B01J19/00
Filed: 1989-06-06
Abstract: PURPOSE:To obviate the contamination of a dispersion by the wear of the medium itself and to improve electrophotographic characteristics by previously pulverizing an org. photoconductive pigment in a dry state to <=5mum average grain size and dispersing the same wet without using dispersion media. CONSTITUTION:The org. photoconductive material is previously pulverized to <=5mum in the dry state and is dispersed wet without using the dispersion media. The sufficient and uniform dispersion is, therefore, executed by the means for dispersing the org. photoconductive material with weak external force, such as agitation, even if a powerful medium type dispersing machine is not used. Any of an impeller agitation method, jet agitation method, shaking agitation method, and ultrasonic dispersion method are usable as the above- mentioned wet dispersion method which does not use the media. The damaging of the photoconductive material in the dispersion process is obviated in this way and the electrophotographic characteristics are improved.

Title: Color palette processing method for image data of bit map form
Inventor: YANAGISAWA TETSUYA
IPC: G06T11/60
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of the processing speed of a computer system without applying any load to a CPU by calculating the AND of every color palette value of both image and pain-out data and deciding a display color by defining the above calculation result as the color palette value of every pixel. SOLUTION: A graphic processing part 4 calculates the AND of every bit between he color palette value of the image data which are written in a graphic RAM 5 and the color palette value of the paint-out data which are written in a working RAM 6. Then the part 4 uses the calculation result as the color palette value of every pixel and converts this palette value into the color data which are shown on a color table to output them to a DAC 7. The DAC 7 converts the color data into the analog signals and outputs them to a display. Thus, an image including 'A' (red) 'L' (green) and its background (black) is shown on the display. As a result, the load of a CPU 1 is reduced and the reduction of the processing speed of a computer system can be prevented.

Title: Scanning picture recording system
Inventor: SHIODA KAZUO
IPC: H04N5/84
Filed: 1978-11-21
Abstract: PURPOSE: To increase the gradation reproducibility by shifting the position of the scanning line with every frame to increase virtually the number of scanning lines and thus eliminating the gap between the scanning lines.  
     CONSTITUTION: The vertical synchronous signal taken out of the synchronous isolation circuit is made to pass through four units of the delay circuits which can be switched sequentially to be then supplied to the vertical deflection circuit. In such constitution, scanning line A is shifted up to dot-line position a1 on the screen and at the first frame and then to position a2 in the next frame. In the same way, the scanning line is shifted subsequently to position a3 in the third frame and then to position a4 in the fourth frame each. According to such shift of line A, the adjacent scanning line B also has the same shift. In this connection, the delay time is set to O for circuit A, 1/2 horizontal scanning period for circuit B, 1/4 for circuit C and 3/4 for circuit D respectively. In such way, the gap between the scanning lines can be eliminated to obtain a hard copy featuring the good gradation reproducibility.

Title: Ink device with inking roller moving in rectilinear and reciprocating shape
Inventor: HARII EMU GURAINAA
IPC: B41F31/14
Filed: 1981-09-14
Abstract: An inking unit for a printing press including a source of ink, a set of ink transfer rollers for establishing an ink film, a distributor roller vibrated endwise for distribution of the ink film and a form roller for applying the ink film to a plate on the plate cylinder. The form roller has a shaft and an outer cylindrical shell, the latter being rotated by surface engagement. A bearing between the shaft and the shell permits relative axial as well as rotational movement. A cam of the cylindrical, or drum, type mounted on the shaft has an endless wavy groove in which is received a cam follower in the form of a roller extending radially inwardly from the sleeve so that the sleeve reciprocates through a single cycle as a result of a single relative rotation of the shaft. The shaft is driven at a speed which causes the frequency of vibration of the form roller to differ from the frequency of vibration of the distributor roller so that the ghost image on the form roller is constantly being displaced and dissipated both peripherally and axially with respect to the image on the plate resulting in substantially ghost-free printing. A clutch is provided for remote switching between two modes of operation.

Title: Antenna device for reflecting mirror
Inventor: NAKAJIMA NOBUO
IPC: H01Q19/12
Filed: 1980-10-16
Abstract: PURPOSE:To remarkably reduce the wide angle level of a reflecting mirror antenna providing a power feeding horn, by multistage location of a cone shield for a major reflecting mirror. CONSTITUTION:Cone shield 8 having k-stages in arranged at a side plate 5 of cylindrical type provided to a main reflecting mirror 3. This shield 8 is formed by linking k sets of cone metallic plates with different vertical angle. Diffractive waves  are produced from an incident wave Ei0 from the mirror 3 at an edge formed with adjacent cone shields, but since a slope angle theta is set smaller around the inlet, te diffractive waves by the edge can be suppressed. Since the level of an incident wave incident to the k-th edge is sufficiently attenuated via distances S1-Sk, the diffractive waves at the k-th edge can be suppressed. Thus, the wide angle level of the reflecting mirror antenna can be reduced remarkably.
