Title: Method for setting reference white level of picture reading device
Inventor: INAGAKI TSUMORU
IPC: H04N1/407
Filed: 1988-01-25
Abstract: PURPOSE:To constantly maintain a white level in the vicinity of a reference white level by reading a white reference line by the line image sensor of plural bits constitution, comparing with a reference white level set beforehand for each bit and controlling the gain of a variable gain amplifier. CONSTITUTION:The reading of a white reference line 20 is executed by a line image sensor 13 prior to the reading of an original. White level data from the line image sensor 13, after being amplified by a variable gain amplifier 21, is inputted to an A/D converter 15 and compared with a reference white level V + ref for each bit. When the white level data are comparatively higher than the reference white level V + ref, the number of overflown bits is calculated by a first counter circuit 22, and when it reaches a previously set value, a count down is executed by an up and down counter 24. Consequently, the gain of the variable gain amplifier 21 is reduced and controlled, the level of the white level data to be inputted to the A/D converter 15 is lowered and approaches the reference white level V + ref.

Abstract: PURPOSE:To improve the patterning precision of a coil conductor and an upper magnetic film by lowering the height of steps near tracks, which are generated when a lower magnetic film is divided into tracks, by an insulating film and forming the coil conductor and the upper magnetic film on it. CONSTITUTION:The first insulating film 12 is formed to cover one plane of a substrate 11 and is subjected to plasma etching to form grooves 13 whose width is approximately equal to a prescribed track width. After a ferromagnetic amorphous alloy is formed on all of the surface of the first insulating film 12 including grooves 13, ferromagnetic metallic materials in parts other than grooves 13 are removed by ion etching or the like to form a lower magnetic film 14. Consequently, the lower magnetic film 14 is packed in grooves 13. Thus, the height of steps due to the lower magnetic film 14 is reduced by the first insulating film 12 in the part near a front gap. Coil conductors 15 and gap spacers 16 are formed by the semiconductor production process like a photolithography technique.
