Abstract: A decorative relief finish pattern is formed by applying to the surface of a coated article or substrate a pattern-forming device composed of a rigid or semi-rigid porous, air-permeable material and having a design thereon. The pattern-forming device, when applied on the surface of the article or substrate a plurality of times, can form such a decorative relief pattern without any undesirable and noticeable protuberance and joints between the first rundown and the subsequent ones.

Abstract: A decorative relief pattern is formed on an article or substrate by first forming a layer of highly viscous material on the surface of the article or substrate, followed by applying a plurality of times to such a layer a roller having a surface design arrangement formed of a single design unit, or of several single design units, each design unit being made up of curved, linear convex bodies. The linear bodies may in fact be continuous lines or disconnected lines. Alternatively, the pattern is formed by applying the roller several times to the surface of the article or substrate while at the same time feeding the highly viscous material thereto. The method can provide an article or substrate with a decorative relief pattern having no directional traces in the direction of the rotary movement of the roller.

Abstract: A decorative relief finished surface is formed by applying to the surface of an object or substrate to be patterned an undercoat of coating material to a predetermined thickness, and forming an uneven pattern having a variety of projections on coated surface a plurality of times with a rolling device having a plurality of convex parts of curved continued, disconnected or perforated line shape which are formed in a random manner, with the intervals between the convex parts being substantially equal to each other, or by spraying coating material with a spray gun so as to form a multiplicity of projections of varying height. Then, the top portions of the projections of the partially hardened surface which extend beyond a predetermined height are pressed with a pressing roll, such that the projections are uniformly flattened to a predetermined thickness while the rest of the convex parts are left unflattened. The pressing roll is made of a hard or semi-hard, air-permeable, porous material.

Abstract: A detecting head for use in an apparatus for reading optically information recorded on a record carrier as a track or tracks comprising an optical system including a projection lens for projecting a light spot onto the track to be read and a device for detecting a relative position between the light spot and the track. The optical system further comprises a device for supporting the projection lens movably in a direction perpendicular to a track direction and a device for driving the projection lens in this direction. The projection lens is further moved in a direction parallel to the track or in a direction parallel to the optical axis of the projection lens.
