Title: Liquid crystal driving method
Inventor: KIKUCHI NAOKI
IPC: G02F1/133
Filed: 1992-08-19
Abstract: PURPOSE:To provide a liquid crystal driving method capable of preventing a drop in contrast and the flickering of a screen. CONSTITUTION:When a liquid crystal panel constituted holding a nematic liquid crystal having relatively high responsiveness is driven by a voltage averaging method, a frame frequency is set at over 80Hz and below 100Hz. As the frame frequency is set high from 80Hz to 100Hz, the period of time for selection is shortened, the response of the liquid crystal during the selection period is made small and thus, the drop in the contrast is prevented and the flickering of the screen is limited for the thining of a frame at the time of a gradation display.

Title: Writing utensil and pigment ink occlusion body
Inventor: TSUJIMOTO MASARU
IPC: B43K8/03
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To prevent characters from becoming unclear or blurred by forcing an inner cotton whose amount applied and cross section are almost uniform in the axial direction into an enclosure with plural tapered ribs in the axial direction on the inner cylinder face and forming the inner cotton in such a manner that the density of the inner cotton is thick on one of the sides in the axial direction and coarse on the other side and further connecting a pen point to the dense inner cotton. SOLUTION: An inner cotton 2 is pressed by ribs 13 to be deformed into a taper shape when the inner cotton 2 is forced into the inner cylinder part 11 of an enclosure 1 from the rear end part A of the enclosure 1, and consequently the fiber density of the inner cotton 2 on the pen point 3 side is higher than the fiber density on the tail plug 4 side. The pen point 3 is molded, like a bar, of a polyester fiber bundle or an acrylic fiber bundle so that the porosity is appropriate. Further the bar tip protrudes from the pen point part 12 of the enclosure 1 by an appropriate size required for writing. The inner cotton 2 deformed into the taper shape is of a higher fiber density on the pen point 3 side compared to the fiber density on the tail plug 4 side. Thus capillarity works intensively toward the pen point 3 so that a smooth and comfortable writing touch is ensured.

Title: Flow rate diagnosing device
Inventor: MARUYAMA HITOTSUGU
IPC: G01F25/00
Filed: 1985-10-03
Abstract: PURPOSE:To monitor the discharge flow meter of a pump at any time and to diagnose accurately and inform the soundness by estimating pump characteristics corresponding to respective pumps by function generators and calculating deviation between estimates. CONSTITUTION:When a flow meter 14 generates an abnormal counted value, an estimate signal S1 outputted by the 1st function generator 21 indicates an abnormal value. Consequently, the deviation signal e12 of a subtracter 24 and the deviation signal e31 have a value larger than a specific level. Then, the outputs ¦e12¦ and ¦e31¦ of absolute value generators 31 and 33 have abnormal values. Then, if the absolute value of deviation exceeds the threshold value (f) of a threshold setter 37, comparators 34 and 35 output a a logical value '1'. Then, the logical values '1' from the comparators 34 and 35 and the output of the logical value '1' obtained by inverting the polarity of the output of the logical value '0' of a comparator 35 by a NOT circuit 45 are inputted to an AND gate. Consequently, the output of the logical value '1' is sent out of the AND gate and supplied to a display device 28 to turn on an alarm lamp.

Title: Fluid-sealed type mount device
Inventor: KATAYAMA MOTOHIRO
IPC: F16F13/00
Filed: 1987-09-03
Abstract: PURPOSE:To produce an excellent vibration isolating effect against input vibration in a wide frequency area, by a method wherein a second moving means, absorbing a difference in a fluid pressure between first and second division chambers is mounted to a second partition member, forming an annular throttled part, so that it is deformable and displaceable by a given amount. CONSTITUTION:A thin section part 62 is formed to a bottom 57 of a second partition member 56. When a difference in a fluid pressure between first and second division chambers 58 and 60 is produced, the thin section is deformed by a given amount, and based on liquid column resonance phenomenon occasioned by deformation of the thin section part 62, input vibration in a frequency area set to the thin section part 62 is effectively shut off. An annular bottleneck part 70 to divide the second division chamber 60 into approximately two parts of chamber parts 66 and 68 is formed. When a difference in a fluid pressure between the two parts 66 and 68 is produced, fluids in the two chamber parts flow to the opposing chamber part through the bottleneck part 70. Based on the liquid column resonance action of noncompressive fluid, input vibration in a frequency area set to the bottleneck part is effectively shut out. This constitution enables provision of an excellent vibration isolating effect against input vibration in a frequency area wider than a conventional means.

Title: Manufacture of high purity metal
Inventor: NAYA KATSUHIRO
IPC: C22B5/02
Filed: 1988-09-07
Abstract: PURPOSE:To accelerate the precipitation speed of pure metals and to improve the productivity in an apparatus, at the time of manufacturing high purity metals by an iodination thermal decomposition method, by regulating the shape of a filament which thermally decomposes a compound of the metals and iodine to the foil one or the sheet one. CONSTITUTION:Material metals 5 contg. impurities of transition metals, particularly the metals such as Ti, Zr, Hf, V, Nb, Ta, Mn, Fe, Co and Ni are arranged at the part of an inner peripheral wall in a closed container 1 and a foil-shape or sheet shape filament 4 of high purity for the metals to be refined is disposed in the center part of the container 1. The inside of the closed container 1 is subjected to vacuum evacuation by a vacuum line 3; after that, I is fed thereto from an iodine-feeding line 2 and is brought into reaction with the material metals 5 into the vapor of iodide. High purity metals formed by the thermal decomposition of the metallic iodine vapor are precipitated on the surface of the filament 4 heated, e.g., to 1200 to 1300 deg.C by an outer electric power 6. Since the shape of the filament 4 is not the wire one but the foil one or sheet one having surface area, pure metals are largely precipitated per unit time on the filament 4 and the productivity in the apparatus can be improved.
