Title: Electrifying brush mechanism, electrophotographic cartridge, electrophotographic recording unit and electrophotographic recorder
Inventor: KASUGA AKIHIRO
IPC: A46B7/10
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent a faulty image from being formed due to an undesirable curling of the bristles of a brush because an electrifying brush roller is reversely rotated when the rotation thereof is stopped and to realize mechanical removing of the soil of the electrifying brush roller by a simple mechanism. SOLUTION: The electrifying brush roller 14 is driven by a motor 30 through a gear 15, a reverse rotation preventing gear 16 and a gear 17. The gear 16 is constituted of a gear 18 having a projection part and a gear 19 having a recessed part where the projection part enters. The recessed part is formed to be a long hole in the circumferential direction and provided with a play between the projection part. Thus, even in the case that reverse rotating force is generated when the rotation of the motor 30 is stopped, it is absorbed by the play and the roller 14 is not reversely rotated. When the motor 30 is started to be rotated, the rotation start time of the roller 14 is delayed with respect to a photoreceptor 12 and the brush temporarily bristles up. Thus, the soil is mechanically eliminated.

Title: Centrifugal casting method
Inventor: KADOSE MASUO
IPC: B22D27/20
Filed: 1978-12-20
Abstract: PURPOSE: To float and remove non-metallic inclusions, segregated elements, etc. together with the air bubbles rising in the center of rotation and cast the clean cast ingot by forming the mold to vertical type and feeding gas into the molten metal from the bottom during rotation.  
     CONSTITUTION: When gas is fed into the molten metal through piping 22 while the mold is being rotated, air bubbles 19 float in the central part of the mold without diffusing. At this time, non-metallic inclusions and segregated element thickened portions 20 of smaller specific gravities are adsorbed by the air bubbles 19 and discharged to the molten metal surface from the central part. The upward current of the molten metal becomes downward current 21 as the air bubbles 19 elute, thereby making natural convection. At the same time, lining 6 causes the solidification of the molten metal around porous bricks 7 to stagnate, thereby maintaining gas supply. Unless the relations of d≤8461N×(square root of h) are established among the inside diameter d of the opening of the head top part refractories 2 of the pouring port and heat metal frame 1, the number of revolutions of mold Nrpm and the recess depth h of the molten metal surface, the molten metal will overflow and fly through the opening during rotation.

Abstract: PURPOSE:To prevent a resonance while matching with the state of a machine at the time of working by adding a variable frequency or a multifrequency component to a command system, finding a resonance frequency from a machine position signal with a driving mechanism, and removing the pertinent resonance frequency component from the command system. CONSTITUTION:A sweeping signal obtained by gradually changing the frequency by a constant amplitude, or a signal having the multifrequency component is impressed to the command system, the resonance frequency is found by frequency-analyzing the machine position signal, and the frequency component corresponding to the resonance frequency is removed from the command system. That is, in the same state as that at the time of the working, for example, in the state in which an object to be cut is placed on a table, the sweeping signal obtained by gradually changing the frequency by the constant amplitude by a sweeping signal generator 9 is impressed as a position command, before the working. Then, the resonance frequency is found by a frequency analyzer 10 with the sweeping signal. On the other hand, a notch filter 11 removes the resonance frequency from the command corresponding to the characteristic of the machine in the same state as that at the time of the working, so that the resonance of the machine can be prevented even when the arbitrary position command is issued at the time of the actual working.

IPC: G21K5/04
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To plot triangular patterns with high accuracy and oblique patterns at high speeds. SOLUTION: While the openings of first transfer mask 23-27 are formed in rectangular shapes, the openings of second transfer masks 8-12 are not formed in triangular shapes, but in polygonal shapes having obtuse angles. At the time of adjusting the size of a rectangular or triangular beam in each opening by setting the other angle than acute angles at 90 deg. or an obtuse angle, the rectangular beam passed through the first transfer masks 23-26 having rectangular openings is moved onto each opening on the second transfer masks 8-11. When the beam is moved, the moving extent of the first transfer mask image on the second transfer mask forms a triangle of a desired size by only using the triangular sections of the openings, and an acute angle is formed by one side of the moving first transfer mask image.  Since an oblique diagram is plotted by driving the diagram into polygons, the number of shots can be reduced and the diagram can be plotted at a high speed.
