Title: Limited element dividing device
Inventor: TOMITA KENICHI
IPC: G06F17/50
Filed: 1988-08-02
Abstract: PURPOSE:To automatically perform limited element division satisfying a requested precision by setting initial element division again based on the discrimination result of convergence of error. CONSTITUTION:An error evaluating means 4 obtains error measure of each element to evaluate the analysis result in accordance with a limited element analysis plan. When a maximum value in the analysis area of error measure exceeds a requested analysis precision, an element division improving means 5 moves the nodal point of element division in accordance with error measure to improve element division. If the maximum value of error measure is not converged though these analysis and nodal point movement are repeated, a state monitor device 6 sends the signal, which indicates that the maximum value of error diverges, to an initial element division resetting means 7. Thus means 7 performs the processing to set initial element division again and sets new initial element division to a limited element analysis means 3 again. Thus, limited element division satisfying the requested precision is automatically performed.

Title: Multicolor developing device
Inventor: MATSUZAKA SATOSHI
IPC: G03G15/01
Filed: 1990-07-23
Abstract: PURPOSE:To prevent the occurrence of vibration at the time of switching a developing unit by constituting a device so that the supporting member of the developing unit may be rotated in a state where a circular member abuts on the surface of a photosensitive member. CONSTITUTION:By rotating the supporting member 4, the respective developing units 3 of a developing device 2 are properly rotated and positioned and selectively opposed to a photosensitive drum 1. A necessary gap between the developing roll 3a of the unit 3 and the photosensitive body 1 is always kept constant by the circular member 6. Since the member 6 is always in contact with the photosensitive body 1 even when the unit 3 is switched, intermittent impact is not given and the fault of an image by the impact is not caused. Then, a positioning member 7 can be used instead of the member 6.

Filed: 1982-11-04
Abstract: PURPOSE:To prepare discoidal tantalum oxide having excellent miscibility with other materials and suitable as an electronic material, by neutralizing a tantalum-containing solution with an aqueous solution of hydrazine, and calcining the resultant precipitate. CONSTITUTION:Tantalum oxide or tantalum chloride is dissolved in hydrofluoric acid at a concentration of about 0.1-100g/l.

Title: Font manager
Inventor: SUMIDA SACHIKO
IPC: G06F17/21
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To obtain the font manager equipped with an effective automatic font extracting function. SOLUTION: This font manager has a host I/F 111 for a two-way communication with a host device 112 and registers a font downloaded from the host device or other peripheral equipment in a disk drive 114. The font registered in the disk drive 114 is managed by a CPU 101 and the manager is equipped with a function which sends only a font registered previously in a controller 100 itself back when an internal font extraction instruction for answering a list of owned font names is sent from the host device 112. When font data are tool many to store in a reception area that the host device 112 has prepared, this function makes it possible to preferentially select a font of high use frequency in a ROM. Therefore, a waste of transmission of a large amount of font data and an overflow of the reception area can be avoided.

Title: Liquid crystal display device
Inventor: IIDA RIEKO
IPC: G02F1/1368
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To obtain a ferroelectric or antiferroelectric liquid crystal display device where a display performance is controlled after manufacture by having a dielectric layer having different electric capacities at an area between a first picture element electrode and a counter electrode and the area between a second picture element electrode and the counter electrode. SOLUTION: Since one picture element is constituted of picture element electrodes 9 and 10 and the thickness of oriented films 22 and 23 differs each other on the picture element electrodes 9 and 10, a different display performance is obtained by independently switching the picture element electrodes 9 and 10. Thus, in the case of switching only the picture element electrode 9, high contrast suitable for a monitor display is obtained because the areas of the oriented films 22 and 23 on the picture element electrode 9 are formed to be thin. Also, in the case of switching only the picture element electrode 10, high speed responsiveness suitable for a moving picture display is obtained because the areas of the alignment layers 22 and 23 on the picture element electrode 9 are formed to be thick.
