Filed: 1990-08-10
Abstract: PURPOSE:To make the maximum use of high speed so as to improve the performance of a whole system by canceling the transmission waiting state of a buffer invalidation request command and storing the content of a register means in a common memory. CONSTITUTION:When write requests are generated for the same areas of two cache memories (M1 and M2) and the writing of data in the cache memory (M1) is faster than that of the cache memory (M2), the buffer invalidation request command from the cache memory M1 is transmitted on a system bus and the cache memory M2 cancels the holding buffer invalidation request command and stores data stored in the register means P0 in the common memory(CM)3. When the issuing of the buffer invalidation request command from the self memory is terminated, a cache memory 1A receives the write request from corresponding CPU and returns the termination response. Thus, high speed being the merit of a copy back system is made the maximum use of and the efficiency of the system can be improved.

Title: Image forming device installing developing device with paper dust removing function
Inventor: MIYAMOTO TAKESHI
IPC: G03G15/08
Filed: 1987-08-25
Abstract: PURPOSE:To remove fine paper dust or talc component remaining on the surface of a photosensitive body by installing a space expanding means for expanding the space between a developing sleeve and a doctor which specifies the height of the crest of developer in the developing sleeve in a specified value larger than the specified value at the time of not forming an image. CONSTITUTION:When the space between the developing sleeve 8 and the doctor 10 is expanded, the height of the napping of the developer in the developing sleeve 8 becomes high. When the best transferred image quality can be obtained at the time of specifying the height of the crest of the developer 16 in the specified value by the doctor 10, the contact pressure and the contact width between the developer 16 and the photosensitive body 1 becomes large if the space is expanded by a solenoid 13 as the space expanding means so as to make the height of the crest of the developer 16 high. Since the surface of the photosensitive body 1 is electrically neutral at the time of not forming the image, the fine paper dust and the talc component remaining on the surface of the photosensitive body 1 are electrostatically attracted to the developer having charges if the contact pressure and the contact width become larger. Thus, the dust can be removed from the surface of the photosensitive body 1 and incorporated in the developer 16.

Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent the outer cylinder of a straight-cylinder-type chimney from being resonated by wind by causing turbulence in the flow of air at the back of the outer cylinder which is the lee side. SOLUTION: A number of holes 8 are provided through the side wall of the upper part of an outer cylinder 7 at the required intervals along the circumferential and vertical directions.
