Title: Method for assembling photosensitive drum
Inventor: ARAI KAZUYUKI
IPC: G03G5/00
Filed: 1992-10-21
Abstract: PURPOSE:To smoothly and accurately assemble the photosensitive drum in safety and maintain stable potential characteristics by making the width of protection paper, used to shield and protect the photosensitive drum, shorter than the length of the drum. CONSTITUTION:When the photosensitive drum 2 is assembled, the width of the protection paper 1 used on the surface of the photosensitive body for shielding and protection is made less than the length of the photosensitive drum 2. This photosensitive drum 2 has width (image area) (a) for actually copying a picture and characters and parts (outside the image area) (b) and (c) where neither the character nor characters are copied because of a process although a photosensitive layer is formed. Then the protection paper 1 only covers the image area (a), but possibly shift to one side during the assembly. In this case, the image area (a) is not covered and trouble is caused, so the minimum size of the protection paper 1 is set to the sum of the size of the image area (a) and a smaller size between the sizes of the parts (b) and (c) outside the image area. Therefore, the operation is performed while the top surface side of the photosensitive body drum is held, and the operation is carried out on a belt conveyor, thereby improving the productivity.

Abstract: PROBLEM TO BE SOLVED: To increase the effect with which raw material adhered to the belt surface is acraped off, assure an easy replacement of the scraping-off plates, prevent powder from falling off from the return run of belt to eliminate cleaning labor and obtain a clean work environment. SOLUTION: A weight 25 is engaged with and secured to a link 24 so that a galvanized iron 18 in a box 17 makes a sliding contact with the surface of the return run of belt with a continually constant pressing force. As a result, any matter (gypsum for example) adhered to the surface of the belt is scraped off at the upper end of the galvanized iron sheet 18. The galvanized iron sheet 18 is thin and its contact surface is smooth so that it is possible, by setting an appropriate pressing force of the belt, to totally scrape off the adhered gypsum with a certain wear. A sponge 20 prevents occurrence of a unilateral strike of the galvanized iron sheet 18 in the width direction of the belt. The galvanized iron sheet 18 is replaced by removing the weight 25 and pressing down levers 23A and 23B.  The box is removed, the galvanized iron sheet 18 is taken out from a groove 16, and another galvanized iron sheet 18j is inserted.

Abstract: PURPOSE:To reduce detent torque by assuming N for number of large teeth and M for number of small teeth, provided in each large tooth, and increasing or decreasing a pitch of the stator small teeth by an integral multiple pitch of 1/(N.M) with respect to a pitch of the small teeth provided in a rotor for a stator having each large tooth.

Forming small teeth 18 in an equal pitch in a rotor 12, the stator 10 forms in its each large tooth 14 four stator small teeth 20 with a pitch space shorter by 1/24 times the pitch of the small teeth 18 of the rotor 12. A change of permeance of the permanent magnet 16 is generated by each small tooth 20 in each large tooth 14, and the permeance change is displaced in its phase by every T/24 assuming T for one period of the basic electromotive voltage wave in each winding U, V, W. And detent torque is based on the period of T/N but negated by each other because the phase is shifted mutually by every pi.

IPC: H04N5/232
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To improve accuracy of predictive correction by detecting a predictive error from an image motion detection circuit, predicting a sharp change from a motion vector and adaptively changing a correction gain. SOLUTION: The detection of the predictive error is performed by an image motion detection circuit 4, besides, the sharp change (fluctuated point) is predicted from the output of a motion vector detection circuit 5 by a prediction circuit 6, and the correction gain is adaptively changed. In this case, a prediction error code comparator circuit 12 compares the output of the image motion detection circuit 4 in a current field with the stored code of the output of a gain control circuit 11 or a prediction circuit 9. When the codes are equal as a result, the predictive correction suppressing hand shaking for the actual motion is indicated but when the codes are different, oppositely, the predictive correction increasing hand shaking is indicated. Therefore, when the result shows the same code, the gain is increased but when the result shows the different codes, the gain is decreased.  When increasing the gain, an optimum value is provided by turning the output of the circuit 4 in the current field into '0' based on the predictive output of the preceding field.
