Title: Color image forming device
Inventor: KAWABATA KATSUICHI
IPC: G03G5/04
Filed: 1995-04-21
Abstract: PURPOSE: To easily form a distinct image excellent in color balance and constituted by superimposing toner images by repeating charge, image exposure and non-contact reversal development to an image forming body provided with a photoconductor layer whose layer thickness is specified. CONSTITUTION: The surface of a photoreceptor drum (image forming body) 10 provided with the photoconductor layer whose layer thickness is 22-50μm is discharged by a precharge exposing lamp 95, and uniformly charged by a charger 20. Meanwhile, an original reading part 25 reads an original image and transmits a yellow image signal to an image exposure means 30 first so as to form an electrostatic latent image consisting of the distribution of low potential area by making yellow image exposing light incident on the surface of uniformly charged drum 10. Then, a developing device 40A develops a yellow toner image by making toner fly. The image-formed surface is charged again by the charger 20 and the image exposure means 30 forms the electrostatic latent image by making magenta image exposing light incident thereon.  At such a time, the potential of the incident area of the image exposing light is sufficiently lowered compared with background potential in the same manner as the yellow electrostatic latent image, thereby, the image excellent in the color balance is formed.

Abstract: PURPOSE:To recognize the page number of blank forms on a buffer memory, and to display the page number by displaying unprocessed printing data page number remaining in the buffer memory when printing operation is interrupted. CONSTITUTION:When printing data A from an external equipment 51 are input, the value of (n) is counted up at every input of one page, every page identification signal, and n=n+1 holds. The value of (n) is counted down at every output of one page section by printing, and n=n-1 holds. When printing operation is interrupted for some reasons, the input of the printing data A from the external equipment 51 is brought to an OFF state by on-line/off-line signals from a CPU 12. A CPU 13 outputs residual-page number display data J through the I/O port 12 at that time, and displays (n) onto a segment indicator 26 on a console panel 21.

Filed: 1978-08-11
Abstract: PURPOSE: To make it possible to apply the aniline point measurement to a wide range of petroluim, while ensuring high measurement accuracy, by using a temperature control circuit, a differential circuit and an arithmetic circuit together.  
     CONSTITUTION: Sample oil and aniline are injected in the same quantity into a sample cell 2, which is equipped with a light source 3 in a bath 1 and a light receiver 4, and are blended by means of a stirring rod 5. The bath 1 is heated by a heater 7 through a rising temperature control circuit 6 through an overall control circuit 14. When the temperature rising rate of the blended liquid reaches 1 to 2°C/min, the value dI/dT (wherein: T stands for the output corresponding to the quantity of the light transmitted; and T stands for the temperature of the liquid) is measured in a differential circuit 9 in accordance with the information from a thermometer 8 and the receiver 4. When this value becomes zero, the circuit 9 and the heating operation are stopped. The output I at that transparent point is stored as I s  in an arithmetic circuit 10, which calculates the relationship of ΔI=I s -I. On the other hand, the mixed liquid is cooled through a temperature lowering control circuit 11 so that the temperature when the value ΔI reaches the preset value is recorded as the aniline point in the printer 13.

IPC: C23F1/00
Filed: 1979-07-31
Abstract: PURPOSE: To make possible good etching by etching a film comprising essentially aluminum by an etchant comprising essentially carbon tetrachloride and boron trichloride.  
     CONSTITUTION: In the case of forming the electrodes and wirings of semiconductor devices with aluminum, dry etching is performed by using the mixed vapor of carbon tetrachloride and boron trichloride as an etchant, whereby the following effects are obtained.
