Title: Foreign matter recovering device for image carrier
Inventor: SAKO HIROYUKI
IPC: G03G21/10
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent a deterioration in the surface of an image carrier for which a single layer dispersion type photoreceptor is used and to remove foreign matter such as paper powder stuck to the surface by providing the image carrier and a foreign matter recovering brush whose top end comes into contact with the surface of the image carrier, in a state where the top end is turned to the downstream side in the rotational direction of the image carrier. SOLUTION: Each fiber of the brush part 65 of a paper powder recovering brush 62 is constituted so that each fiber comes into contact with the surface of a photoreceptor drum 5, in the state where each fiber is turned to the downstream side in the rotational direction of the surface of the drum 5. The brush part 65 is lightly energized to the surface side of the drum 5 by the elasticity of a base part 63. Further, a negative charge is applied to the brush part 65 and the paper powder stuck to the drum 5 is easily electrified to a positive polarity, so that the paper powder can be surely recovered by the application of the negative charge to the brush part 65. Further, this brush part 65 is tuned to the downstream side in the rotational direction of the surface of the drum 5, so that the contact pressure of the brush part 65 with respect to the surface of the drum 5 becomes small to reduce the deterioration in the surface of the drum 5.

Title: Mono-block type enclosed lead battery
Inventor: NAKAMURA KENJI
IPC: H01M2/12
Filed: 1989-04-07
Abstract: PURPOSE:To prevent the bulkhead of each cell from being strained, and also prevent electrolyte from being moved as well as to reduce cost while an reduction in exhaust air valve installation in number is being accompanied with by providing the bulkhead of each cell with a vent hole with a specified diameter, thereby providing one exhaust air valve for more than 2 cells. CONSTITUTION:A vent hole 1 is provided for the upper section of the bulkhead 3 of each cell so that the space on the upper section of each cell shall be for common ventilation. The aperture of the vent hole 1 shall be less than 0.2mm<2> but equal to or more than 0.002mm<2>, which allows air to pass through, but prevents electrolyte from being moved to a lesser extent. In this case, the values for these limits have been determined through experiments. This causes gasous pressure developed by each cell to be common when a battery is in operation while preventing the bulkhead 3 from being strained owing to gasous pressure, there is thereby no need for an reduction in battery capacity with the bulkhead 3 thickened. In addition, one exhaust air valve 7 is good enough for an assembly of more than 2 cells, the cell can thereby be reduced in number as compared with the case where the valve is provided for each cell.

Inventor: MORITA MASAKATSU
IPC: G06T7/00
Filed: 1991-04-19
Abstract: PURPOSE:To inspect the quality of tile units in an unmanned state. CONSTITUTION:The lightness T1-T9 of the exposed surface of each tile 2 of a tile unit 1 is found and a reference lightness range is fixed by adding or subtracting a threshold to or from the mean value Ta of the lightness T1-T9 calculated by Ta=(T1+T2+...+T9)/9. The deviation tn from the mean lightness Ta is calculated on all picture elements and whether or not each tile falls in the range is mutually discriminated, and then, the number of picture elements falling in the range is used as the number of tile surface picture elements. The number of tile surface picture elements is compared with the preceding number of tile surface picture elements. Regarding sheets, the deviation of each sheet is calculated by finding the means value Sa of the sheets and the numbers of sheet surface picture elements are compared with each other. Therefore, the shifting or stripping off of each sheet 3 of the tile unit 1 can be surely detected.

Title: Method and apparatus for removing pollutants from gas
Inventor: FURANKU RUISU DOBIASU
IPC: B01D47/02
Filed: 1978-07-20
Abstract: Air or other gases containing contaminants or requiring treatment are moved into at least one substantially continuous sheet of treating liquid at the entrance to a streamline flow passage having a smoothly curved convex interior surface progressively decreasing in cross-sectional area in direction of flow. A nozzle mounted adjacent the entrance end of the flow passage generates one or more substantially continuous sheets of treating liquid covering the entrance to the passage. The passage has a convex throat and an exit smaller than the entrance so that the gas and treating liquid entrained therein move through the passage at an accelerating velocity with smooth, substantially unidirectional flow, and are discharged therefrom with no discernible turbulence or splashing. The gas and the treating liquid are discharged from the flow passage into an eliminator chamber of large volume, whereupon the treating liquid and any entrained contaminants drop out of and are separated from the gas. The invention is particularly adapted to paint spray booths for removal of paint overspray from the booth ventilating air prior to discharge of the air to atmosphere.
