Title: Developing device for electrophotographic method
Inventor: MASUDA JITSUO
IPC: G03G15/08
Filed: 1985-12-09
Abstract: PURPOSE:To detect toner concentration accurately by providing a slight gap at the upstream side of a sensor head between the sensor head and a developing roller and further providing a control plane which has bored reducing holes as necessary. CONSTITUTION:The control plate 12 provided on the upstream side of the sensor head 9 is a plate made of a nonmagnetic material which has plural round holes (reducing hole) 13 bored in the center, the front end is bent to the downstream side to form the slight gap on the peripheral surface of the sleeve 4 of the developing roller 2, and the base end side is fixed to a ceiling part 14. The developer 6 in the developing tank 5 is controlled by the control plate 12 and not supplied to the side of the sensor head 9 by more than required, and even when the developer is cut off by a doctor 7, it never stays at this part and the flow becomes smooth. Consequently, even when the sensor head is left without being used for a long period and the concentration of the developer 6 nearby the sensor head 9 is high, the agitated developer 6 from the developing tank 5 flows in immediately on the start of a copying machine and the concentration recovers in a short time, so that correct toner concentration is detected. Consequently, picture quality is prevented from degradation at the start of the copying machine.

Title: Apparatus and method for processing of digital image signal
Inventor: JIEEMUZU ROBAATO UITEIKAA
IPC: H04N5/262
Filed: 1994-11-15
Abstract: PURPOSE: To remarkably reduce the cost of a device and method for processing digital picture signal by eliminating the need of line store. CONSTITUTION: In some cases, it becomes necessary to enlarge or reduce a raster-scanned picture at the time of displaying the picture on, for example, part of a computer display. The enlargement or reduction is attained by dividing the picture into a plurality of picture cells having a horizontal width narrower than that of the whole picture. Then a smoothing algorithm is successively applied to the line of each cell so as to generate new pixel data which vary depending upon the converting operations to be performed. A converting means stores the lines of data from one cell, with the number of lines being varied depending upon the used specific smoothing algorithm. In order to make the scanning of the picture cell constitution easier, additional synchronous pulses are generated. The pulses are composed of cell horizontal and vertical synchronizing pulses.
