Abstract: PURPOSE:To control oxide film formed at annealing to the thickness of the extent without requiring pickling stage, by annealing steel sheet having a specified Cr content at suitable temp. and dew point, in annealing furnace of gaseous atmosphere having a specified compsn. composed of gaseous H2 and N2. CONSTITUTION:Steel sheet contg. 1-19wt% Cr is annealed by annealing furnace of gaseous atmosphere composed of 0-75% gaseous H2 and the balance substantially gaseous N2. Temp. of the annealing is regulated to a prescribed temp. in 650-900 deg.C range determined from Cr content of the steel sheet. Dew point of the gaseous atmosphere is controlled to a prescribed dew point of 0--40 deg.C range determined from annealing temp. of the steel sheet. The annealing carried out for <=60sec soaking time while using continuous annealing furnace for common steel sheet is favorable. By the titled annealing, thickness of oxide film formed on steel sheet is controlled to <=500Angstrom and pickling stage thereafter is made unnecessary.

The Si substrate 1 is lapped thereon, in the manner in which its front surface faces downward, and the SiO2 layer 3 and the SiO2 layer 4 are heated and stuck in an oxidizing atmosphere. Then a substrate 8 after sticking is dipped in an aqueous solution of 2.5% HF (electrolytic solution) 10, and the N-type Si substrate 1 of about 0.1-0.01OMEGAcm is eliminated by electrolytic etching. Then an active layer whose thickness is uniform and less than or equal to 1mum is stably obtained.

Abstract: PURPOSE: To slightly reduce the line width of a character to obtain a neat form of the character by preliminarily setting values for line width reduction of the character in a table at the time of rounding processing and using these boundary values to perform omission or raising processing. CONSTITUTION: The direction attribute of a point in the middle of processing is obtained, and coordinate data of the point is multiplied by 48/256. When rounding processing of a decimal fraction of the operation result is next performed, the processing is performed based on a table corresponding to the detected direction attribute. That is, when the direction attribute of the point in the middle of processing is, for example, '1', fractions of 0.9 and over are rounded up as 1 and the rest is cut away with respect to the X coordinate after reduction, and fractions of 0.2 and over are rounded up as 1 and the rest is cut away with respect to the Y coordinate after reduction. This boundary value table for raising and omission is so set that the character width is slightly reduced. By this constitution, the character width is slightly reduced to obtain a neat form of a character.

Filed: 1987-09-30
Abstract: PURPOSE:To obtain stable copied image quality by equipping a concentration sensor of toner which is made to adhere to the specified area of a photosensitive body, grounding a conductive developing tank through a variable resistance circuit and varying resistance values according to the concentration of the toner so that electrification quantity can be properly kept. CONSTITUTION:The developing tank 9 is grounded through the variable resistance circuit 20 and the toner concentration detecting sensor 24 is disposed by facing an image non-formed area positioned on the end part of the photosensitive body 7. Based on the reflected light quantity from a facing surface, the concentration of the toner is detected and conducted to a resistance value control circuit 21 so as to vary the resistance value of the variable resistance circuit 20. When the concentration of the toner is high, the resistance of the resistance circuit 20 becomes low and the quantity of the toner adhering to the surface of the photosensitive body can be reduced. On the contrary, when the output from the concentration sensor 24 is small, the resistance value of the circuit 20 becomes high and the toner adhering quantity is increased. Even in case of image forming action after leaving the titled device for a long time, the toner adhering quantity can be prevented from increasing and the stable copied image quality can be always obtained.
