Title: Brush electrification control system
Inventor: WANO MASAHIRO
IPC: G03G15/02
Filed: 1986-12-17
Abstract: PURPOSE:To correct the drop of charging potential by controlling an impressed voltage outputting means in accordance with the charging potential of a recording body and keeping the charging potential at a prescribed value. CONSTITUTION:The surface potential of the recording body 2 charged by a conductive brush 1 is recognized by a surface potential recognizing means 3, a voltage control means 4 is driven and the output voltage, i.e. a brush impressing voltage, of an impressing voltage output part 5 is controlled by controlling a control voltage to be applied to the part 5 so that the surface potential is set up to a prescribed value. Since the voltage to be impressed to the conductive brush 1, i.e. the brush impressing voltage, is adjusted in accordance with the surface potential of the recording body 2, the charging potential can be prevented from being dropped due to the deterioration of charging capacity of the brush 1. Even if the brush 1 is deteriorated due to the increase of recording capacity and the charging capacity is dropped, the deterioration can be compensated by changing the brush impressing voltage, so that the maintenance of the brush 1 can be reduced.

Filed: 1990-11-08
Abstract: PURPOSE:To quickly locate damaged or worn portion and quantitatively determine the condition by holding a visual sensor in the direction at right angles to a slit laser beam receiving section and moving the sensor in parallel with a wall to be measured. CONSTITUTION:The image of the surface of a tile 1 is taken for a slit to obtain the coordinates (P11, P12) of both edges of the tile 1. The attitude of a hand is then changed so that the z axis in which a visual sensor is directed is perpendicular to the straight lines P11, P12. Taking the image of the surface of the tile 1 for a slit again, the edge points P11, P12 are measured. Then a hand is moved to a point without changing attitude by a certain distance in the direction x in the sensor coordinate system to take the image of the tile 1 surface for a slit to measure the tile 1 edge points P21, P22. The attitude of the hand is then changed so that the line P11, P12 is the y axis and the direction of P21 is the x axis. Movement in the x axis direction with the hand attitude unchanged enables calculation of all the measured data by the difference only in the z axis.

Filed: 1986-12-18
Abstract: PURPOSE:To obtain vivid pictures by applying a non-selecting voltage to the other liquid crystal panel while one liquid crystal panel is driven in the share driving phase period. CONSTITUTION:In a period Tt-up when an upper liquid crystal panel is driven to successively scan row-side electrodes and the share driving phase period is scanned, a non-selecting voltage Voff is applied to a lower liquid crystal panel.
