Filed: 1993-05-06
Abstract: PURPOSE:To reduce the scattering of a developer caused by the sudden decrease of air pressure in a developer layer by preventing irregularities in the developer layer due to the vibration of a developer layer thickness regulating member. CONSTITUTION:The level difference 17c of 0.4-1mm is formed in a direction away from a developing roller 6 in a place where the distance from the abutting part C of a thin layer blade 17 is <=1mm, the free end part 17a of the thin layer blade 17 on the downstream side in the moving direction of toner T is constituted as a thin part 17d smaller than the difference in level 17c and a small space 17e is formed in a region where the thin part 17d faces the developing roller 6. Thus, even if the thin layer blade 17 is vibrated, the free end part 17a of the thin layer blade 17 can be prevented from coming into contact with a toner layer just after passing the abutting part C. Moreover, even if the toner layer passes the difference in level 17c, the sudden decrease of the air pressure inside can be suppressed by the small space 17e, so that the scattering of the toner T can be suppressed.

Title: Emulator
Inventor: OBA SHIRO
IPC: G06F11/22
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To enable the normal execution of data transmission/reception even when pulse width is shorter than a specified standard by multiplying a clock for synchronous communication and supplying an operating clock to an emulator control circuit. SOLUTION: An emulator control circuit 21 fetches data supplied from a debug support unit 12 synchronously with a clock CLK-A for synchronous communication and performs data processing synchronously with an operating clock CLK-C. At such a time, since the clock CLK-A for synchronous communication is multiplied into operating clock CLK-C to be supplied by a clock multiplication circuit 22, when the pulse width of clock CLK-A is shorter than the AC standard, corresponding to such a state, the pulse width of clock CLK-C is shortened as well. Therefore, data processing at the control circuit 21 can be performed within real data holding time and data can be normally exchanged between the unit 12 and the control circuit 21.
