Title: Developing device of copier
Inventor: NAGAYAMA KATSUHIRO
IPC: G03G15/01
Filed: 1992-08-27
Abstract: PURPOSE:To decrease splashing of a toner from a developing tank by controlling the rotation speed of rollers in the developing tank when rotation of rollers is started and stopped in a manner that the rotation speed is slowly and continuously changed from the rotation speed in the developing period. CONSTITUTION:Rollers in the developing tank, especially, stirring rollers 32, 33 and developing roller 34 in a developing case 35 are controlled in a manner indicated by the time-rotation speed diagram. In the diagram with axis of abscissas for time and the axis of ordinates for rotation speed, the rotation speed during starting rotation in period t1-t2 for magenta developing is continuously increased to the constant speed Vc for development in period t2-t3 and then rotation is decreased in period t3-t4 from Vc to zero. Thereby, drastic change of the rotation in the starting and stopping periods is prevented, which decreases splashing of the toner. Thereby, mixing of toners in a developing device even when the copier contains lots of color toners is prevented, and thereby, reproducibility of colors can be improved for full-color copies and the inside of the machine is not contaminated with toners.

IPC: B01D29/11
Filed: 1989-09-01
Abstract: PURPOSE:To prevent consolidation of a gel layer and restrain permeation rates of valuable matters from falling and further make an apparatus smaller by connecting filters with ceramic filter in series, imparting pressure to liquids to be filtered on the side of uppermost stream to reduce differential pressure. CONSTITUTION:Liquid to be treated in a circulation tank 11 is circulated by means of a circulation pump 12 through filters 13 and 14 connected in series so that said liquid is passed through the inner side of ceramic filters 13a and 14a, while part of said liquid is passed through the ceramic filters under differential pressure between the inner and outer sides thereof, wherein the differential pressure is controlled to a predetermined pressure by means of pressure control valves 17b, 17d. In this manner, even when the feed pressure of the liquid is raised to increase the feed rate, it is not necessary to keep the differential pressure so high that a gel layer is consolidated, preventing thereby falling in filtering rates due to consolidation and restraining permeation rates of valuable matters from falling down, and further, since the filters are connected in series, enlarging the circulation pump 12 and associated pipings is not needed, so that the apparatus can be mede smaller.

Filed: 1986-09-27
Abstract: PURPOSE:To operate an explosion-proof mechanism at relatively low pressure by forming a plurality of grooves in the bottom of a battery container, and specifying the width of the flat part in the bottom of the groove to given times the thickness of the thin part formed by the groove. CONSTITUTION:Cross-shaped grooves 3 are formed in the bottom of a battery container 1. The bottom 3a of the groove 3 is flat and the width W of a flat part 3a1 of the bottom 3a is 1.4-1.5 times the thickness t of a thin part 4.

Filed: 1999-08-13
Abstract: PROBLEM TO BE SOLVED: To shorten a time for processing and developing plotting commands to bit map data by advancing to a next band when a band divided by a predetermined width in a vertical scanning direction of one page is a blank region, and processing and developing plotting commands to bit map data when the band includes a plotting region.

Abstract: PURPOSE:To detect the overload state of a processing unit with respect to a set timer time by providing a circuit detecting a difference between the set timer time and a data processing execution time during the timer time and a circuit raising an alarm depending on the comparison of the detected result with respect to a prescribed time.

Then the content set by the unit 1 is fed to an input terminal of a comparator 8 via a decrement counter 7. Thus, the comparator 8 compares the content of the counter 7 with a reference value preset to a preset value counter 9 and raises an alarm signal AL when the content of the comparator 8 is equal to or lower than the reference value. Then the unit 1 can know the excess of load relatively to the set value of the timer time to correct the timing of refresh or the timer time of the period at the post-processing.
