Title: Cleaning device for image forming device
Inventor: TANAKA KAZUMOTO
IPC: G03G21/00
Filed: 1987-12-17
Abstract: PURPOSE:To constantly attain stable cleaning action regardless of the electrification characteristic of toner to be used by disposing a means which controls the surface potential of a cleaning roll. CONSTITUTION:A charge imparting means 7 which controls the surface potential of the cleaning roll 4 is disposed at the downstream of a scraper 5. The charge imparting means 7 controls the surface charge of the cleaning roll 4 so that it becomes an opposite polarity to the electrification polarity of the toner to be used. Thus, even if toner which is different from the other toner to be used in electrification characteristic is mixed, cleaning faulty, toner scattering, and image quality deterioration never occurs, and stable and well cleaning action can continuously be maintained.

Title: Floating gate type nonvolatile memory
Inventor: ARAKAWA HIDEKI
IPC: G11C16/04
Filed: 1987-12-15
Abstract: PURPOSE:To erase a floating gate type nonvolatile memory electrically by a method wherein a negative voltage is applied to a control gate and positive holes are injected into the floating gate. CONSTITUTION:A negative voltage, for instance, -3V--10V, which is approxi mately equal to a writing voltage is applied as a drain voltage Vd to a control gate 6 to erase a nonvolatile memory electrically. If a negative voltage is applied to the control gate 6, the breakdown strength of a P-N junction between a drain 3 and a substrate 1 at a part just under a floating gate 4 is degraded and the P-N junction is liable to be easily broken down. Therefore, pairs of positive holes and electrons are produced in the vicinity of the drain 3 just under the floating gate 4 and the positive holes are injected into the floating gate 4 by an electric field induced by applying a negative voltage to the control gate 6.
