Title: Method for continuously pickling steel strip
Inventor: IKEZAKI EIJI
IPC: B21B45/06
Filed: 1991-04-23
Abstract: PURPOSE:To reduce the pickling time or to make the equipment compact by increasing the pickling capacity of a pickling soln. at the time of pickling a hot-rolled steel strip. CONSTITUTION:When a steel strip 1 is continuously pickled and descaled, the strip 1 is heated by a preheater 6 to the temp. close to the b.p. of a pickling soln. 3 under atmospheric pressure. The pickling soln. in a pickling tank 2 is then heated, boiled and bubbled or high-temp. vapor or gas is blown into the tank 2 to generate bubbles in the pickling soln., and the strip is descaled. Consequently, an active pickling reaction is initiated immediately after the strip is introduced into the pickling tank, the boundary layer formed on the strip surface in pickling is broken by bubbling, and the pickling rate is drastically increased since the soln. is agitated under high temps.

Title: Braille detecting method
Inventor: FUTAYADA KATSUYUKI
IPC: G06K9/20
Filed: 1979-07-24
Abstract: PURPOSE: To make it possible to read a sheet of one-sided or both-sided braille paper at a high recognition rate by deciding unevenness of a point by making use of the shade and highlight of light by detecting unevenness.  
     CONSTITUTION: When concave point 22 of braille paper with a convex point on the top side and the concave point on the reverse side is irradiated with light 26 from an upper right part, shade 27 is formed where no light strikes and highlight part 28 is formed where the light strikes perpendicular. Further, shade part 27 and the highlight part are also formed at convex point 21, but they are formed reversely. This phenomenon is utilized to decide unevenness. When the concave point is segmented, information on its highlight is increased by one scan in the subscan direction. This can be obtained by OR between information one line before and information on the current line. Next, shade information 61 is delayed by four lines to equalize timing in terms of time and both the pieces of information are AND-ed, so that points will well be separated. Then, since information 61 pairs with highlight information 62, unrequired points are discriminated and eliminated. Therefore, both-sided braille information paper can be read with accuracy.
