IPC: B41M5/52
Filed: 1982-09-21
Abstract: PURPOSE:To obtain an image having high resolution and clear and excellent color development by a method wherein a recording liquid of a specific water system is made to stick, by an ink jet method, onto a material prepared by forming on a supporting substance a layer which contains the particles of a filler and on which recording is to be made. CONSTITUTION:A coating liquid prepared by a method wherein the particles of a filler, such as silica, whose particle size is preferably about 1-30mum, and a binder such as polyvinyl alcohol, are dispersed in a medium and adjusted is applied onto a supporting substance, and thereby a material having a layer which is formed with the indefinite shapes of the particles of said filler appearing on the surface and on which recording is to be made is obtained. Then, the recording liquid whose water content is adjusted to be within 20-90wt% and which is introduced into minute holes is jetted from an orifice communicating with said minute holes so that it sticks onto said material whereon recording is to be made. Thereby a clear image is obtained without running or oozing of color even when another recording liquid of different color is made to stick onto the same place overlappingly.

Filed: 1991-07-04
Abstract: PURPOSE:To prevent trouble which is caused by a wiring pattern by securing and arranging a wiring area around a component in accordance with component characteristic information on the number of used pins of each component. CONSTITUTION:A rectangle which includes the outer shape of an actual component and has the smallest surface area is found as an approximate value of the component outer shape as to all components to be arranged (101) and all components are arranged so as to be close to each other (102). A free area is found from the sum of the area of the arranged components and the area of a substrate (103) and it is judged from the area of the free area whether or not a wiring area can be defined around the components for rearrangement, when there is not the free space, the process is ended. When there is the free area, the wiring area around each component is found from the characteristic information on the component, e.g. the number of used pins and the free area and the allocated wiring area is stored as an enlarged figure of the rectangle found as the approximate value of the component outer shape (104). Then the components are rearranged on the printed board in accordance with the outward shape of the respective reset components.

Title: Cutting crop in continuous hot rolling line
Inventor: YOSHIDA KUNIO
IPC: B21B15/00
Filed: 1989-06-26
Abstract: PURPOSE:To prevent occurrence of drawing phenomenon by measuring a plate thickness difference (called 'wedge') between both sides of a plate width of a sheet bar after coarse rolling and a strip wedge, and changing the cutting length on both sides of the plate width corresponding to the change of the wedge ratio based on both measurements at the time of cutting a tail end crop. CONSTITUTION:For a sheet bar 3 after coarse rolling, its thickness is measured, at both sides and its center by an entrance side width direction thickness gauge 14, and obtained information is sent to an upper computer 18. The thickness of a strip S after finish rolling is also measured by an exit side width direction thickness gauge 16 similarly, and obtained information is sent to the upper computer 18, where wedge ratio as the wedge divided by the plate thickness is calculated, and predicted value of partial elongation quantity is determined. A turn shift quantity DELTAl is calculated based on this, it is transmitted to an oil pressure control panel 24, and a crop shear 12 is turned right and left by a cylinder 28 to cut a rear end part of the sheet bar 3. Though the lengths at both sides become different from each other, they become almost equal to the final stage of finish rolling, thereby drawing phenomenon such as breakage of an edge can be prevented.

Title: Image forming device
Inventor: YAMAZAKI KOJI
IPC: G03G15/02
Filed: 1987-06-30
Abstract: PURPOSE:To improve the durability and reliability of a photosensitive body consisting of an amorphous silicon photosensitive body by providing no grid electrodes to all of corona dischargers which subject the above-mentioned photosensitive body to electrostatic charging and destaticizing treatments. CONSTITUTION:No grid electrodes are provided to all of the corona dischargers 2, 5, 7, 9 which subject the photosensitive body 1 to the electrostatic charging and destaticizing treatments. As a result, the generation of spark discharge is obviated and, therefore, even if the photosensitive body 1 is the amorphous silicon photosensitive body having easy susceptibility to damage by the spark discharge, the photosensitive body 1 is not damaged and is thereby rendered with higher durability and reliability. An image forming device which makes best use of the various outstanding characteristics of the photosensitive body 1 is thus obtd. A loss of a grid effect and the easy tendency to the generation of unequal electrostatic charge are resulted from the provision of no grid electrodes to the corona dischargers 2, 5, 7, 9, but the electrophotographic characteristics of the amorphous silicon photosensitive body are superior to the characteristics of the other photosensitive bodies. The high image quality is thus maintained stably for a long period of time.
