Filed: 1993-04-09
Abstract: PURPOSE:To prevent occurrence of the cracking on the surface of a cast slab by using a heat-removing variable mold which can adjust the cooling speed corresponding to the casting speed by a mold where the heat-removing characteristics are variable in the continuous casting of steel. CONSTITUTION:The level 3 of the molten steel surface is positioned downward by 10mm or more from the boundary with the ceramics on the copper plate surface 1 without the ceramics in a normal case when the casting speed is over 0.5m/min by using the mold where the upper part of the mold for the continuous casting made of the water-cooled copper plate 1 is notched, and the ceramics 6 is attached thereto. When the casting speed is reduced to 0.5m/min or below, level 3 of the molten steel surface is positioned at the ceramics surface 6 to the upper part of the mold to execute the continuous casting of steel. In addition, the heat-removing characteristics can be variable by embedding the heating element into the upper part of a water-cooled continuous casting mold made of copper. This constitution prevents the surface temperature of the mold from being dropped, the thickness of the film of the powder from being increased, and also prevents occurrence of the cracking on the surface of the cast slab.

IPC: C09D5/00
Filed: 1980-06-20
Abstract: PURPOSE: A paint for preventing internal reflection of an optical member, highly effective for the prevention of internal reflection, which is obtd. by the incorporation of a metal oxide having refractive index higher than that of the optical member and high blackness.  
     CONSTITUTION: Optical member 1 such as a lens or prism consists of a lens made of glass of high refractive index of 1.7W1.8 and its side face 1a having a roughly sanded surface which does not transmit light, is coated with internal reflection- preventing paints 2. The paint 2 is prepared by mixing a clear resin obtd. by the copolymn. of a styrenated melamine resin and an acrylic resin, with a metal oxide having high blackness and refractive index of 2.0W3.0 which is higher than that of the optical member 1, as a main pigment. When the paint 2 is applied on side face 1a of the optical member, most of incident light 3 is not reflected as reflected light 4 but refracted as refracted light 5 toward the paint 2 and absorbed in the paint 2. Consequently, internal reflection rate is reduced and internally reflected light is sufficiently absorbed.

Abstract: PROBLEM TO BE SOLVED: To secure a confidential function for a FAX that has no memory by performing the scramble/descramble operations to replace the positions of received image data with each other on the same line based on a prescribed rule. SOLUTION: When a CPU 11 receives a call set in a confidential mode, a FAX serving as a device of the receiving side reads a confidential number (k) included in the call and then reads a scramble number (m) out of a scramble number area 174 in response to the number (k) stored in a confidential number area 171 of a confidential table 17T contained in a RAM 17. Then the CPU 11 performs the factorial expansion of the number (m) to store the coefficient thus obtained in an array fac [0 to 7] and produces a scramble displacement table as an array scr [0 to 7]. The CPU 11 decodes and scrambles the received data via a codec 18 and also outputs them to a printer 23. When the images are restored, the printed data are read by a CCD 21 and then descrambled through the adverse working of the array scr [0 to 7] and printed out by the printer 23.
