Abstract: PROBLEM TO BE SOLVED: To always completely clean an image carrier, to lighten a burden imposed on the image carrier and a cleaning means and to prolong their lives by controlling the cleaning ability of the cleaning means in accordance with the operation condition of an image forming means. SOLUTION: This device has a 1st cleaning mode and a 2nd cleaning mode where the cleaning ability (actuation time, in this case) of a cleaning means 233 is different from each other as a mode for cleaning a transfer drum 202. When a register number is <=2 in a state where a monochrome mode and a full color mode are set, the 1st cleaning mode is executed. Thus, waste in a cleaning time is eliminated and the lives of a photoreceptor drum 206, the transfer drum 202, and the cleaning brush 233 are prolonged. Meanwhile, when the register number exceeds 2 in a state where the full color mode is set, the 2nd cleaning mode is executed. Even in the case the drum 202 is seriously contaminated, the drum 202 is surely cleaned.

Title: Back-filling block
Inventor: OKABE AKIRA
IPC: E02D17/04
Filed: 1984-04-03
Abstract: PURPOSE:To obtain strong back-filling blocks of a simple structure by using flat plates set in parallel with each other, while paired wedges slidably attached between the flat plates, and a cotter with a taper to fit the distance between the tiered portions of the wedges. CONSTITUTION:A back-filling block consists of flat plates 5 and 5' set in parallel with each other with freely set intervals, paired wedges 1 and 1' slidably attached between the flat plates 5 and 5', and a cotter 3 with a taper to fit the distance between the tiered portions 2 and 2' of the wedges 1 and 1'. The block is set between a waling and a sheathing wall and driven into the ground, whereupon a stretching force is produced between the waling and the sheathing wall due to the expansion of the distance between the flat plates 5 and 5' while the flat plate 5' is closely attached to the sheathing wall. The structure of the back-filling block can thus be simplified and the manufacturing cost of the block can be reduced. The block having high strength and toughness can thus be repeatedly used without danger of breakage and disorder.

Abstract: PURPOSE:To dispense with the exposure of a movable part and a special plate for detecting motion by integrating acceleration twice, and calculating the quantities of movement of a pointing device on a plane in the X-axial direction and the Y-direction. CONSTITUTION:A movement quantity measuring circuit 21 has an accelerometer 31 and an integrator 32, acceleration data outputted to a signal line 32 by the accelerometer 31 by detecting the acceleration is inputted by the integrator 33, which integrates the data twice to calculate and output the movement quantity of the pointing device to the signal line 32. A movement quantity measuring circuit 22 also has exactly the same structure. Then when the pointing device is moved on the horizontal plane 40 from a position 41 to a position 42, the X-axial accelerometer 31 of the pointing device detects the acceleration (g), which is integrated once by the integrator 33 to obtain time variation in speed (v). Further, this is integrated once more by the integrator 33 to detect the X-axial movement quantity (x) and the Y-axial movement quantity is detected similarly. Consequently, the exposure of the movable part is eliminated and the need for a plate for motion detection is eliminated.

Abstract: PURPOSE:To switch a signal switching circuit to a video side only when a video signal exists at a video input terminal by switching a signal switching circuit to a video input terminal side with the detecting output of a video signal detecting device. CONSTITUTION:When a video supplied to a video input terminal 4 is watched, a change-over switch 19 is closed and an and circuit 15 is closed. When a video signal is supplied to a video signal input terminal 4, an output terminal 14 of a video signal detecting circuit 12 comes to be a high level. As this result, since an output terminal 16 of the and circuit 15 comes to be a high level, a tuner video change-over switch 5 is switched to a video side. Consequently, a video signal connected to the video input terminal 4 is reflected through a switching circuit 5 and a color demodulating circuit 10 to a CRT 11. On the other hand, when the video signal does not exist at the video input terminal 4, the output of the detecting device 12 comes to be a low level, the change-over switch 5 is connected to a tuner side as it is and not switched to a video side.
