摘要： An improved squeegee roller particularly suited for use in an instant camera has a texture formed by stud-like bumps. A complex contour is provided to the roller by varying the heights of the bumps along the roller surface. In a method and apparatus for producing the roller a pulsed laser beam is used to produce the bumps and the energy of each pulse is varied according to a predetermined program to adjust the height of a bump formed.

摘要： A compound roll for rolling composed of a shell made of adamite having a carbon content of 1.4-2.5 weight % and a core made of forged or cast steel, the shell being metallurgically bonded to the core by casting an adamite melt around the already prepared core, and the shell having a large residual compressive stress. The adamite shell has a composition consisting essentially, by weight, of 1.4-2.5% of C, 0.6-0.8% of Si, 0.8-1.0% of Mn, 0.5-2.5% of Ni, 1.0-4.0% of Cr, 0.2-2.0% of Mo and the balance being essentially Fe. The residual compressive stress of the shell is desirably at least 20 kg/mm.sup.2 so that cracks are effectively prevented from penetrating into the depths of the shell, thereby preventing the breakage of the compound roll at a roll body thereof.

摘要： A rotor shaft for steam turbines has a journal portion to be supported by a bearing. The journal portion is provided with a sleeve for a bearing made of an alloy of bainite structure comprising 0.04 to 0.35% C, 0.2 to 2% Mn, less than 1% Si, 0.5 to 3% Cr, less than 5% Ni, and less than 0.5% V, having yield strength of more than 50 kg/mm.sup.2 and Lt of less than 24. The sleeve is divided into two semicylindrical segments, and they are arranged on a small diameter portion of the shaft adjacent to said journal portion, welded into one piece, and subjected to stress relief treatment at a temperature higher than a temperature of tempering conducted to the sleeve before welding. The welded sleeve is fitted on the journal portion by shrink-fit so that the sleeve can be served as a superior bearing.

摘要： Method and apparatus for producing cylindrical products having a range of hardness through a cross section such as a roll. The method includes conventional forging and heat treatment steps with or without the addition of a rapid water quench derived from direct impingement of a quench medium on the product as it rotates in a horizontal position, followed, as a final heat treatment, by subjection either to direct flame impingement in a horizontal, rotating condition or flame heat in a vertical furnace while rotating, again followed, preferably, by a drastic quench, and, also preferably an extremely low temperature deep freeze operation to thereby convert substantially all austenite to martensite. The invention makes possible the production of rolls capable of usage from original diameter to scrap diameter without reconditioning.
