Abstract: In a sealing device for a rolling bearing wherein the clearance between an outer race and an inner race is sealed by a sealing plate fixed to the outer race side, the sealing plate has on its inner periphery an axially extending inner lip, a radially extending outer lip and an intermediate lip extending between said two lips and having the tip end thereof divided into two directions. The inner race has on its outer peripheral surface adjacent to the end thereof a concave seal groove having an inner shoulder and an outer shoulder having a diameter smaller than that of the inner shoulder. The inner lip of the sealing plate cooperates with the inner shoulder of the seal groove to form an inner sealing portion between the inner lip and the inner shoulder. The outer lip of the sealing plate cooperates with the outer shoulder of the seal groove to form an outer sealing portion between the outer lip and the outer shoulder.

Abstract: A vibration detection apparatus detects the vibration of an optical system such as a camera by dividing the incoming rays of light and causing pairs of photosensors to receive the divided rays of light and then comparing the shifts in the phases of the signals output from the pairs of photosensors.

Abstract: A slide way bearing has a track shaft and a slide member to be slidably mounted on the track shaft. Track shaft has on its side surfaces first ball rolling grooves of circulation cross-section. Slide member has at its inner surface second ball rolling grooves corresponding to the grooves in the track shaft, and within the slide member through-holes at the back of the respective second grooves. The first and second grooves and through-holes form ball circulating paths. The intersecting points of lines of contact between the balls and the first ball rolling grooves are located outside of the polygon formed by connecting the centers of the balls. The circulating paths lies on the plane substantially parallel with the bottom surface of the track shaft.

Abstract: This specification discloses a method of manufacturing a retainer for solid type roller bearing, a retainer manufactured by the method, and a cutting edge member used in the method. The specification also discloses the formation of roller retaining pawls around a roller retaining hole by cutting and removing post-like projections over a predetermined length by the cutting edge member, the post-like projections being formed on the wall surfaces of rectangular holes of a ring-like retainer member.

Abstract: A hydrogen-evolution electrode having a coating comprising at least one metal oxide selected from the group consisting of nickel oxide and cobalt oxide and at least one metal selected from the group consisting of nickel and cobalt has been found to exhibit extremely low hydrogen overvoltage and to have not only high catalytic activity but also high durability.

Abstract: A process for recovering trioxane from an aqueous solution containing trioxane and triethylamine by the distillation separation process which comprises feeding an aqueous solution containing trioxane and triethylamine to the first distillation column, distilling out triethylamine, trioxane and water from the column top of the first distillation column, withdrawing an aqueous solution containing the major part of the trioxane present in the fed solution from the column bottom of the first distillation column, feeding the withdrawn solution to the second distillation column and taking out the substantially whole quantity of the trioxane fed to the second distillation column from the column top of the second distillation column.

Abstract: In a planetary-roller transmission for transmitting power from one rotating shaft to another by a plurality of planet rollers pivotally supported, in contact with the outer periphery of a sun roller connected to the first rotating shaft and also with the inner periphery of an internal contact ring secured to a stationary member, by a carrier connected to the second shaft, all or any of the rollers and ring is an elastic one, which consists of a plurality of thick-walled cylindrical parts spaced apart axially of the associated shaft, a cylindrical part thinner than the thick-walled parts, with its inner or outer periphery serving as a surface to contact the mating roller or ring, and disk-shaped parts thinner than the thick-walled parts and connecting the both sides of the thin-walled cylindrical part separately to the thick-walled parts, so that, when the thick-walled cylindrical parts are pressed toward each other at the both outermost sides, the diameter of the thin-walled cylindrical part is changed, and t

Abstract: A conical roller bearing has a side plate of substantially L-shaped cross section fitted to the larger diameter side end portion of the inner peripheral surface of an outer race. The inner end surface of the side plate and the end surface of the larger diameter portion of a retainer are axially opposed to each other so that the inner end surface and the end surface of the larger diameter portion bear against each other when the cone has moved axially outwardly.

Abstract: An optical system for directing a light image of a scanned original to a charged photosensitive surface of an electrophotographic copying apparatus, includes an imaging lens located between the original and the photosensitive surface. The optical axis of the imaging lens is directed normally to the original and the lens is movable in a direction substantially parallel to the original during scanning of the original. At least one mirror is disposed to receive the imaging rays from the imaging lens to reflect them onto the photosensitive surface, and each mirror is moved synchronously in a different direction from the lens to maintain the rays reflected from the original at a proper position during scanning.

Abstract: A method of welding for hard surfacing comprises feeding a powdery mixture, prepared by adding at least one of the powders on NbC, VC, and TiC to the powder of an alloy steel containing either Fe, Ni, and Cr, or Fe and Cr as the chief components, to an arc produced between a base metal of iron or steel and a nonconsumable electrode shielded by an inert gas, and thereby forming a weld metal on the base metal.
