Title: Character processor
Inventor: MASAKI KATSUMI
IPC: B41J5/00
Filed: 1980-09-29
Abstract: PURPOSE: To make even the position of the print end of each line, by laying out evebly the character rows within a certain region when the character inhibited at the head or end of aline is automatically processed and printed out.  
     CONSTITUTION: When the characters of plural character rows are printed in even division, the region to be divided evenly is designated by the even division code and the characters are supplied among the divided regions. Thus an inhibit process is automatically executed to the supplied character row, and at the same time the character existing at the head or end of the line is excluded out of its position. Then an inhibit code is inserted there. With this process, the inhibit code is eliminated by the character line existing before the code. In this case, the print pitch is varied for the partial pattern forming a matrix pattern to discriminate character from a logogram character. Then the shift of the print position is compensated at the end of the character row of each line.

Title: Developing device and process cartridge loading it
Inventor: HIBI TAKASHI
IPC: G03G15/00
Filed: 1992-04-28
Abstract: PURPOSE:To equalize abutting pressure between a blade and a developing roller, to prevent toner from entering and retaining on the back surface side of the blade and to eliminate the density unevenness of an image. CONSTITUTION:The developing roller 2 is rotatably at the aperture part 1a of a developing container 1 and the elastic blade 5 fixed to a supporting member 3 is made to abut on the roller 2 in a trunk abutting state. The almost whole surface of the blade 5 is covered with a spacer 6 fixed to the supporting member 3. Besides, a gap S formed among the container 1, the blade 5, the supporting member 3 and the roller 2 is closed by an elastic seal member 7. At this time, the seal member 7 is prevented from being brought into contact with the spacer 6 and the lower edge 7a thereof is aligned with the lower edge 6a of the spacer 6. Thus, since the spacer 6 is not falsely deformed by the seal member 7, the abutting pressure between the blade 5 and the roller 2 is made uniform and the toner is prevented from entering and retaining on the back surface side of the blade 5.

Title: Reacting method for liquid
Inventor: YAMAGUCHI ITARU
IPC: C08F2/00
Filed: 1978-11-07
Abstract: PURPOSE:To facilitate the recovery of reaction products by making the mixing of reacting liquid components stronger and more rapid by a means that different kinds of reacting liquid components are interflowed and reacted on a rotary matter. CONSTITUTION:When making a reaction between different kinds of liquids each of which has reaction rate greatly different from each other, e.g., in the case of ionic polymerization, etc., different kinds of liquids are interflowed in the vicinity of right above the center of rotation of a rotary disk or bowl, whereupon an outside force exerts on the rotary direction and the centrifugal direction of the reacting liquid components as they rotate, while a shearing force is produced in the reacting liquid layers due to a movement speed gradient caused by outside force and frictional resistance on the rotating surface and in its inside. Thus, the strong and rapid mixing of the reacting liquid components is performed and they are diffused and dropped toward the outside of the rotating surface. In this way, the reaction of liquids can be made without the use of any diffusing solvent.

Title: Optical low pass filter
Inventor: IMADA SATORU
IPC: G02B27/46
Filed: 1989-05-30
Abstract: PURPOSE:To practically sufficiently suppress a carrier component by emitting separated luminous fluxes having approximately equal brightness from parallelogrammic or diamond emission position patterns. CONSTITUTION:After two separation positions PA and PB constituting one side of a parallelogram or a diamond are formed by first and second double reflection plates 31 and 32 having separation directions orthogonal to each other, a third double reflection plate 33 having +45 deg. or -45 deg. separation direction is laminated to form two separation positions PC1 and PC2 in positions to which separation positions PA and PB are moved in parallel. Consequently, emission positions patterns PTN1 and PTN2 which emit a set of four separated luminous fluxes from separation positions PA, PB, PC1, and PC2 forming apexes of the parallelogram or the diamond are generated when separated luminous fluxes are transmitted through first to third double reflection plates 31 to 33. Thus, the harmful carrier component is practically sufficiently suppressed.

Title: Combustion control system
Inventor: TANAKA EIICHI
IPC: F23N1/00
Filed: 1985-06-21
Abstract: PURPOSE:To enable the multistep control of burning rate of a burner with a compact construction, by providing a plurality of burners weighted by binary system, opening or closing burner nozzles by means of shape memory alloys, applying electric current thereto. CONSTITUTION:Each burning rate of burners 1a-1e shall be a weighted value therefor according to binary system. Suppose said value for 1a to be 300 kcal/h, then the value for 1b will be 600 kcal/h and 4,800kcal/h for 1e, whereas nozzles 2 also shall have a nozzle diameter corresponding in size to respective burning rate therefor. Fuel will be burned in each of the burners 1a-1e dependently on the opening conditions of each of opening and closing valves 3a-3e provided at nozzle means. By the combination of burners, thirty-one sorts of burning rates can be obtained ranging from min. burning rate 300 kcal/h to max. one 9.300 kcal/h with a stepwise difference of 300kcal/h. Control of hot-water temperatures is carried out by opening or closing the opening and closing valves 3 at nozzle means through a controller 7. When an electric current is applied to springs 17 from a controller 7, the temperature of springs made of shape memory alloys will rise to cause a valve 15 to open at a temperature higher than the transformation temperature. Since the burning rate and the control function can be varied linearly, the control system can be made simple, so that circuits for converting digital signals from a microcomputer to analogue signals can be omitted.
