Abstract: PURPOSE:To prevent a density in the central vicinity of an image from being light by giving a blade a curve shape reverse to a deflection curve generated since a blade edge faced to a sleeve is deflected in being pulled at a sleeve side in a uniform distributed load way by means of a magnet. CONSTITUTION:To the edge of a blade 3, a curve S is given at an ant-sleeve 2 side from the ideal line of the blade 3 edge from an ideal straight line A in which an interval between the blade 3 and sleeve 2 indicated by a broken line can be made linear. When the blade 3 is deflected in receiving the uniform distributed load magnetic force from the sleeve 2 by giving such a curve deltato the edge of the blade 3, the edge of the blade 3 is made to coincide with the ideal line A of the blade edge. Consequently, when the blade 3 receives the magnetic force form the sleeve 2, a distance between the blade 3 and sleeve 2 is made fixed anywhere. Thus, a density lowering in the image central vicinity generated since the thickness of a toner layer in the central vicinity is thinned can be prevented.

Title: Preference replacement system for sequential reusable resources
Inventor: KAWAI TOSHIYA
IPC: G06F9/46
Filed: 1988-07-15
Abstract: PURPOSE:To improve the processing efficiency of the title system by checking an under-process flag when a task gives an access to the sequential reusable resources and giving a process request to the running task when said flag is set. CONSTITUTION:A process A request task 1 secures the sequential reusable resources 5 and sets an under-process flag 51 at the resources 5 to reset the flag 51 when the due reference or replacement is through. Then the presence or absence of the flag 51 is checked when a process B task 2 gives an access to the resources 5. If the flag 51 is set, a process request is given to the running task 2. While the due reference or replacement is carried out when the flag 51 is reset. Thus the CPU process is never stopped and no suspended state is produced before the running task 2 can be locked. As a result, other events set on the tasks can be performed at one time and furthermore the processing efficiency is improved since the locking and unlocking actions are carried out by its own task.
