Title: Cleaning device
Inventor: KOYAMA HAJIME
IPC: G03G21/10
Filed: 1987-02-12
Abstract: PURPOSE:To enhance cleanability by using magnetic power having such a grain size distribution where peaks of the distribution curve exist at at least two points. CONSTITUTION:The grain size distribution of the magnetic powder has the two peaks of the distribution curve. The grains sizes of the respective peaks exist on both sides of the average grain size of the magnetic powder. More specifically, this magnetic powder is a mixture composed of the magnetic powders of two kinds of the grain size groups; large grain sizes (for example, 200-400mum) and small grain sizes (for example, 40-100mum). The powder which contacts a residual toner 11 of a copying machine on a photosensitive drum 2 is the magnetic powder 12 of the small grain sizes and the contact probability of the toner 11 and the powder increases. Since the part of the ears except at the top end of a magnetic brush is formed of the powder 13 of the large grain sizes, the rigidity of the ears increases. The cleaning performance is thereby improved.

Title: Continuous hot dipping apparatus for hoop
Inventor: ONO YOSHIO
IPC: C23C2/40
Filed: 1980-03-07
Abstract: PURPOSE:To increase the passing speed of hoop, by installing bridle rolls for adjusting tension in the rear of a pretreating furnace, and by adjusting the tension in the pretreating furnace and the tension of the hoop at a nozzle separately. CONSTITUTION:Bridle rolls 14a, 14b driven by a motor are installed as substitutes of a turn down roll in the position, where the turn down roll is formerly arranged, in order to remove the relation between the tension of the hoop 13 in the furnace and the tension of the hoop at the nozzle 9. The tension of the hoop in the pretreating furnaces 2, 3, 4, 5 is set by the adjustment of the output of the motors of a tension-adjusting means 1 and of the bridle rolls 14a, 14b. The tension of the hoop at the nozzle 9 is set by the adjustment of output of motors for the bridle rolls 14a, 14b and a tension bridle roll 12. As a result, the tension at the nozzle 9 is set at a high value, so that there are no chances of contraction or out off of the hoop 13 in the pretreating furnace.

Title: Electrophotographic copying device
Inventor: YAMAMURA NAOKI
IPC: G03G15/00
Filed: 1990-02-08
Abstract: PURPOSE:To reduce running cost and to surely control the life of a drum unit by deciding whether the drum unit is new or old when it is mounted in a main body, rewriting a memory that it is already used and clearing a counter when the drum is new and continuously counting without clearing the counter when it has the history of use. CONSTITUTION:When the drum unit 1 is mounted in the main body 6, a control means 41 switches a power source device 20 to output a rated voltage to a fuse 10 and a decision means 30 judges whether the fuse 10 is normal or abnormal. In the case of judging that the fuse 10 is normal, the control means 41 switches the power source device 20 to overvoltage so as to cut out the fuse 10. Namely, a new memory stored by the drum unit 1 itself is rewritten that it is already used and the counter 9 is cleared as an initial condition for the new drum unit 1. In the case of judging that the fuse 10 is abnormal when the drum unit 1 is mounted in the main body 6, the counter 9 is not cleared. Therefore, the waste of paper and a large quantity of distinct printing are prevented. Thus, the running cost is reduced and the life of the drum unit is surely controlled.

CONSTITUTION:When an original point ORG is not previously fixed, the dimension drawing processing executes the setting processing 1 of the original point ORG. Namely, a horizontal line and a vertical line passing on the original point ORG are drawn. In preparatory processing for displaying as distributed shape about the center line, parallel lines symmetrical about the center line passing the original point ORG are formed and the dimension between both the horizontal lines is calculated and generated. On the other hand, the dimension from the original point ORG is calculated individually at portions which are not distributed about the center line and respective line dimension values are generated. About circules or taps belonging the same group, the dimension is generated based on following dimension and the generated dimension is drawn and displayed.

Title: Projection type display device
Inventor: AIDA KEN
IPC: G03B21/28
Filed: 1989-02-08
Abstract: PURPOSE:To enhance the brightness of a picture displayed on a screen by making the linearity in vertical or horizontal direction of a picture displayed on a screen of a projection type cathode ray tube nonlinear in the midway, providing a prescribed curvature in the vertical or horizontal direction of a mirror and displaying a picture with a different aspect ratio from an aspect ratio of the picture of the projection type cathode ray tube. CONSTITUTION:The linearity in the vertical direction of a picture is decreased in the midway (upper and lower elongation) as shown in figure C by controlling a vertical deflection system and the scanning line interval is decreased toward the center. Since a prescribed curvature is given in the vertical direction of the mirror 3, a magnified high vision picture displayed on a screen 4 corresponds to a picture displayed on a screen 1a of a projection tube 1 whose upper and lower parts are shrinked. Thus, the high vision picture whose aspect ratio is 16:9 is displayed as a picture whose aspect ratio is 4:3 on the screen 1a of the projection tube 1 and the substantial high vision picture whose aspect ratio is 16:9 is displayed on the screen 4.
