Title: Manufacture of electric charge generation material dispersion liquid for manufacturing electrophotographic photosensitive body
Inventor: HONGO KAZUYA
IPC: G03G5/05
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing electric charge generation material dispersion liquid for manufacturing an electrophotographic photosensitive body which shows good electronic photo characteristics, excels in dispersion property in binding resin solution, and shows good electronic photo characteristics when an electrophotographic photosensitive body is manufactured by simple operation. SOLUTION: When electric charge generation material dispersion liquid for manufacturing an electrophotographic photosensitive body is manufactured by dissolving binding resin into solvent to prepare binding resin solution and adding and dispersing an electric charge generation material to the binding resin solution, the binding resin is heat-treated under reduced pressure or atmospheric pressure in gas atmosphere before the binding resin is dissolved in the solvent. It is preferable that the dissolution is done in inactive gas atmosphere such as nitrogen gas as gas atmosphere. When an electric charge generation layer is formed by using the electric charge generation material dispersion liquid, it is possible to manufacture an electrophotographic photosensitive body having excellent electrophotographic characteristics.

IPC: H03K21/08
Filed: 1982-07-13
Abstract: PURPOSE:To use extensively a measuring range remarkably at the positive side, by adding an approximate half value of a prescribed count value corresponding to a minimum display unit to an output count value to designate the sum as a correcting count value, and bringing together the value to integer numbers the minimum display unit corresponding to the count value. CONSTITUTION:An output volue of an A/D converter 3 is inputted to an adder 41 and a subtractor 42, and a signal S1 having a polarity of the converter 3 is inputted to the adder 41 and the signal S1 of the converter 3 is inputted to the subtractor 42 via an inverter 43. When the signal S1 is positive, the adder 41 performs the operation of [output count +20,000] and when the signal S1 is negative, the subtractor 42 performs the opeation of [20,000 count - output count] for outputting the output value of the circuits 41, 42 via an OR gate 44. Thus, the measuring range is used extensively twice for the positive polarity.

IPC: H04L69/40
Filed: 1987-05-18
Abstract: PURPOSE:To improve the debug efficiency by connecting a logic analyzer through a GP-IB standard interface between a debug device and a device to be debugged. CONSTITUTION:Denoting an object controller by a controller 31, a logic analyzer 4 decodes the sent order and sends a trigger condition signal to the controller 31 of the target machine 3. When the controller 31 of the target machine 3 runs, the trace data is collected based on the preset trigger condition and the collected trace data is stored in a trace buffer in the logic analyzer 4. Next, when the execution order of the trace condition display is sent to the logic analyzer 4 via the same interface as that at the setting, the logic analyzer 4 sends the trace data collected earlier to the host machine 1. Thus, the test execution personnel has only to apply a very simple man-machine interface to the host machine 1.

Abstract: PURPOSE:To make a gradual variation of a passage cross sectional area toward an opening by a method wherein two disk plates having a substantial conical shape are overlapped to be movable from each other, a plurality of flexible arcular opening or closing plates are disposed between the disks, one end of each of these opening or closing plates is pivotally supported at one disk plate and the other end of each of these opening or closing plates is pivotally supported at the other disk plate. CONSTITUTION:In the event that a disk plate 12 is rotated in a counter-clockwise direction through a knob 19, a pivotal supporting point of the disk plate 12 with an opening or closing plate 14 draws a circular locus with a pin 17 being applied a pivot point O17 and another locus with a center of the disk plate 12 being applied as a pivot point O12. Accordingly, as the disk plate 12 is rotated in a counter-clockwise direction, a midway part of the opening or closing plate 14 is curved by an amount corresponding to a difference in displacement between the circular locuses and an assembly of these several opening or closing plates 14 forms a funnel-like shape and is projected in one direction and an area of an opening 20 at an inner circumferential part is reduced. To the contrary, in the event that the disk plate 12 is rotated in a clockwise direction, the degree of curvature in the midway part of the opening or closing plate 14 is reduced and a projecting amount is reduced and then an area of opening 20 is increased. If this opening is disposed in the air passage, the cross sectional area of the passage is gradually varied toward the opening 20.
