Title: Production of casting mold
Inventor: KAI TOSHIO
IPC: B22C9/02
Filed: 1983-03-14
Abstract: PURPOSE:To eliminate the need for a binder to obtain initial strength and to prevent the collapsion of a mold in the stage of rapping by bringing a refrigerant into contact with a granular material which is made wet and packing the material onto a pattern surface while pregressing the process of freezing. CONSTITUTION:A driving source 2 for rotating a sand mill 1 is operated and molding sand is continuously supplied from a supply mechanism 6 and a chute 7 through a supplying port 5 into the mill 1. On the other hand, water is fed from a feed mechanism 8 into the mill 1 and is kneaded with the molding sand, thereby producing the wet molding sand. A refrigerant is supplied to the wet molding sand from a refrigerant supplying mechanism 9 into the mill 1 to progress the process of freezing the molding sand. The molding sand frozen like sherbet on progression of the freezing is accelerated by the compressed air to be ejected from a booster 12 and is sprayed and packed through a conveying conduit 13 and a nozzle 14 into a molding flask mounted therein with a pattern. The molding sand sprayed and packed onto the pattern freezes and solidifies and permits rapping when held for a specified time.

Title: Method and device for driving liquid crystal panel
Inventor: KAMIYA KIYOSHI
IPC: G09G3/36
Filed: 1993-02-05
Abstract: PURPOSE:To provide the driving method and device which can make a display of constant picture quality irrelevantly to changes of driving conditions when a display is made on an active liquid crystal panel by a pulse width modulation system. CONSTITUTION:A pulse voltage as one factor of variation of voltage versus transmissivity characteristics 120 and charging characteristics 12 of a liquid crystal pixel is selected from among variation factors of the characteristics. There is a difference in charging characteristics between (a) and (b) owing to a difference in pulse voltage. For the cases (a) and (b), pulse width data for gradations 0-4 are prepared. When a driving voltage is a pulse voltage of (a), pulse width data corresponding to gradation versus pulse width of (a) is selected and the liquid crystal panel is driven by a pulse voltage modulated to the pulse width. Consequently, neither white nor black blur is generated and a false outline and a quantization noise become inconspicuous, so that deterioration in picture quality is eliminated.

Title: Solid-black preventing device of electrophotographic copying machine
Inventor: IWASAKI SHINICHI
IPC: G03G15/043
Filed: 1982-03-16
Abstract: PURPOSE:To prevent the formation of a solid-black part on transfer paper and to  reduce the consumption of toner, by arranging for a photoreceptor a light source for  blank exposure which provides the photoreceptor with the blank exposure having a  distribution corresponding to the size of an original and a position on a platen according to detection signals of sensors distributed so that they detect reflected light from  the original corresponding to the size of the original and the position on the platen. CONSTITUTION:The original 1 is illuminated by the exposure lamp 3 during copying  operation and its reflected light is projected on the photoreceptor by a reflecting  mirror 6 and a lens-mirror system which is not shown in a figure; and a CdS sensor 7  detects only reflected light from the original and an original cover through a light  shielding plate 8. Therefore, when the copying operation is carried out while no original is placed and the original cover is not closed, there is reflected light from neither  the original surface nor the reverse surface of the original cover, so the CdS sensor 7 detects almost no light. The circuit which includes four CdS sensor 7 as shown in the  figure allows a comparator 12 to generate an output when a potnetial at a point A  becomes higher than that at a point A and the blank exposure lamp is turned on to  expose the photoreceptor.
