Title: Continuous annealing method for stainless steel strip
Inventor: ISHIBASHI GENICHI
IPC: C21D1/70
Filed: 1989-11-20
Abstract: PURPOSE:To continuously anneal a stainless steel strip with good thermal efficiency without forming oxide scales and flaws on the surface of the steel strip by applying an aq. soln. contg. the powder of oxide ceramics and alkali silicate on the surface of the steel strip and annealing the steel strip at the time of continuous annealing of the stainless steel strip. CONSTITUTION:Rolling mill lubricants, etc., are removed from the surface of the stainless steel strip S by a degreasing tank 4 at the time of annealing of the stainless steel strip after cold rolling. Since the surface of the stainless steel strip is nearly a specular surface, the heat absorptivity thereof is not good and, therefore, the viscous aq. soln. prepd. by adding water to the powder of the oxide ceramics, such as Al2O3, SiO2, and TiO2, and alkali silicate salt, such as water glass in such a manner that the ratio of the alkali silicate salt in the solid content in the aq. soln. attains >=50% is applied on the surface. Such steel strip is subjected to direct type heating and annealing in an annealing furnace 6 consisting of a heating furnace 7 and a cooling furnace 8 to form the fired film of <=50mum thickness. The fired film of the ceramics system is peeled by a device 31 having brush rolls 32 and the steel strip is passed through a nitric acid tank 41 where the oxide scale on the surface of the stainless steel strip is removed; thereafter, the steel strip is subjected to rinsing 12 and drying 13, by which the continuously annealed stainless steel strip having excellent surface characteristics is produced with the good thermal efficiency.

Title: Method and device for encoding and decoding image
Inventor: OYAMA KOICHI
IPC: H04N19/625
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To solve the problem that an encoding (decoding) device incorporates an adder A, -1 multiplier which multiplies -1, a 1/2 multiplier which multiplies 1/2, a rounding device R which obtains an integer by rounding a decimal part, and multipliers M each of which makes arbitrary multiplication, each of the multipliers M requires a long time for multiplication, has a complicated structure and the number of which is inverse proportional to the speed of the device. SOLUTION: Four two-point (reverse) converters TW which rotate by π/4 or -π/4 can be replaced with one four-point (reverse) converter TQ. Since an encoding (decoding) device is constituted by using the new four-point (reverse) converter TQ containing no multiplier M, the number of multipliers M incorporated in the device is reduced to 15/39 of that of the conventional encoding (decoding) device and the operating speed of the device can be increased to an extremely fast speed. In addition, the constitution of the device becomes simple and the device can be constituted in an integrated circuit at a low cost.
