Title: Magnetic particle jet-type image forming apparatus
Inventor: ITO NOBORU
IPC: G03G15/09
Filed: 1994-06-15
Abstract: PURPOSE:To achieve high-speed operability, robustness against external disturbance factors, and a simple construction by jetting magnetic particles using magnetic field. CONSTITUTION:When a magnet roller 10 is rotated, shifting magnetic fields are generated around a sleeve 7 by magnetic poles N1-S4. With the shifting of magnetic field, magnetic particles 9 are limited to a constant amount by a limiter portion 8 and then conveyed to a region 18 where the sleeve 7 and a magnetic needle 13 face each other. When an excited magnetic pole opposite to the shifting magnetic pole of the magnet roller 10 is formed at the tip of the magnetic needle 13 by an instruction from an image information output apparatus, the magnetic particles 9 passing through the region 18 receive flying force directed to the opening of a nozzle 6. The thus-flown magnetic particles 9 jet out of the nozzle 6 and are retained onto an image-carrying drum 20 by the remaining magnetic force. The magnetic particles 9 are then conveyed together with rotation of the image-carrying drum 20 and transferred to a paper sheet or the like by transfer means. With this arrangement, a simple construction capable of high-speed operation and robust against external disturbance factors can be provided.

Abstract: PURPOSE:To discriminate a collected state of powder and to detect its full state by providing a cut-off means between a carrying means for carrying the powder and its driving system, stopping a rotation by cutting off driving in case when an overload has been given to the carrying means, and also, detecting it. CONSTITUTION:When a collecting vessel 16 becomes full, carrying reaction force to a carrying auger 7 becomes large, and a load torque of the carrying auger 7 increases. Subsequently, at the time point when this load torque has exceeded some value, that is, the collecting vessel 16 has become full, a torque limiter 8 works, driving to the carrying auger 7 from a driving motor 10 is cut off. When a rotation of the carrying auger 7 is stopped, a stop signal is outputted to a control part 21 by a detecting device 17, and a display for instructing a rejection of a collected developer is displayed on a display part 24a of an operating panel 24. In such a way, an operation failure and damage of parts are prevented, and also, a full state can be detected stably.

Title: Semiconductor memory device
Inventor: TOYODA KAZUHIRO
IPC: G11C5/06
Filed: 1978-10-30
Abstract: PURPOSE: To reduce the influence dependent upon parasitic resistances of a word line by changing the emitter area of an active element, which determines the holding current of a memory cell, so that holding currents of respective memory cells may be fixed.  
     CONSTITUTION: In case that holding currents i 1 Wi n  are flowed to memory cells CEL 1 WCEL n , which consist of transistors TrQ 1  and Q 2  and resistances r 1  and r 2 , through a word line, holding currents i 1 Wi n  are different in memory cell positions due to the voltage drop dependent upon parasitic resisrances R11WR1n, R21 and R2n of the word line, and holding currents of cells near the center are smaller than the average holding current. Therefore, the area of emitters e1We7 of an active element which determines holding currents is so set that this area may be large for cells near the center and may be smaller according as going toward left and right ends. As a result, inequality of holding currents can be compensated, and the noise margin of each memory cell can be made uniform.

Abstract: PROBLEM TO BE SOLVED: To provide an electrifying roller capable of preventing oil component and low molecular component of a conductive elastic layer consisting of rubber material from oozing and concentratedly leaking into a photoreceptor drum gap, excellently electrifying the photoreceptor drum, and having satisfactory durability. SOLUTION: In this electrifying roller 201 provided with the conductive elastic layer 203 on a conductive supporting body 202 and a resin layer 302 in which conductive particles 301 are dispersed on the conductive elastic layer 203, the conductive particles 301 in the resin layer 302 are reduced as nearer to an outer surface 304 in the thickness direction 305 of the resin layer.  Since the conc. of the conductive particles 301 in the resin material are reduced as nearer to the outer surface 304 in the thickness direction of the surface layer, the volume resistivity of the surface layer are increased as nearer to the outer surface 304, therefore the sufficient current required for electrification is allowed to flow in the roller radial direction, but the current along the roller outer surface is hardly caused to flow, thus the electrifying current is prevented from leaking into the photoreceptor drum gap along the roller outer surface.
