IPC: G03G15/08
Filed: 1981-11-24
Abstract: PURPOSE:To coat a developer supporting member with magnetic toner in a uniform thin layer by providing a magnetic field generating means opposite to a magnetic doctor blade, and thus allowing the magnetic grains to stay between the developer supporting member and magnetic doctor blade. CONSTITUTION:When toner particles 4 passes through a magnetic brush formed of magnetic grains 6, the magnetic grains 6 are attracted strongly by a counter electrode 35 to a sleeve surface and brought into slide contact with the sleeve surface, so the toner particles 4 are scraped off from the sleeve surface. Then, a curtain of the magnetic brush having an enough gap for the toner particles to pass through is formed of the magnetic grains 6 between a blade 5 and a sleeve 2. When the toner particles 4 pass through the gap, its passing amount is restrained and also they are charged to the opposite polarity to the charge polarity of a latent image by friction with the magnetic grains 6 to be coated on the sleeve in a uniform thin layer 4a. Then, the toner layer 4a is carried through the rotation of the sleeve 2 to a developing area facing a photosensitive drum 1, thereby performing the development 1a of a static charge pattern on the photosensitive drum 1.

Title: Fixing method and device of diaphragm
Inventor: YANAI TAIJIROU
IPC: F16J3/06
Filed: 1982-10-27
Abstract: PURPOSE:To improve durability by providing thick section in the center of diaphragm then pressure inserting a boss in the center of back plate to a thick guide at the central hole section thereby requiring only one back plate and reducing compression stress when fixing a rod. CONSTITUTION:When pressure taken through a negative pressure take-in port 27 is lower than pressing force of spring, the thick section 23a of diaphragm 23 is pressed against the case through the spring 26. As the negative side pressure lowers to overcome the spring 26, the diaphragm 23 is pulled to the negative pressure side. Using the fact that the pulling force is applied only on the negative pressure side during operation, only one rear metal is requird to avoid concentration of stress thus to improve durability and to reduce rod fixing man power.

IPC: G03G15/00
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To precisely maintain the toner density in developer at a prescribed reference value, by combining a predictive toner consumption by a dot counter with the toner density detection in the developer by an ATDC sensor, in a digital electrophotographic copying machine. SOLUTION: The device is a copying machine constituted so that an electrostatic latent image is formed on a photoreceptor based on the digital image signal, and the latent image is developed by the toner. When humidity inside the machine is normal humidity (YES in step S16), the toner density in the developer is detected by the magnetic ATDC sensor, and the toner feeding is performed based on the detecting value (step S17 and S18). When humidity inside the machine is deviated from the normal humidity (NO in step S16), the toner feeding is performed (step S19) based on the toner consumption predicted from the dot count value as the density information contained in the image signal (step S12 and S13). Preferably, fuzzy inference is applied for deciding the toner replenishment quantity.

Abstract: PURPOSE:To enable an operator to be supplied with sound to obtain only a desired sound message by selecting the output destination of the sound message. CONSTITUTION:A plant monitoring device 11 transmits a sound message request signal (f) to a sound output controller 13 in accordance with the process or the state change of a plant. The controller 13 divides the sound message information (a) into the sound information (c) and the output destination information (b) respectively and sends the information (c) and (b) to each speaker 17 and a sound information selector 14 respectively. The selector 14 receives the information (b) and the degree of need to the sound message of an operator sent through a console 15 in the form of request signals e1 and e2 and decides whether or not the sound message should be informed to each output destination. This results of decision are used to the open/close of a switch 16 in the form of switch changeover signals d1 and d2. Therefore, the information (c) is transmitted to a speaker 17 only when the switch 16 is closed and then to the operator as a sound message.
