20100165463 | TRIANGULAR-PYRAMIDAL CUBE-CORNER RETROREFLECTIVE ARTICLE HAVING CURVED REFLECTIVE LATERAL FACE - To provide a retroreflective article formed of many triangular-pyramidal cube-corner retroreflective element pairs. One-side groove angle formed between a cross line between a plane vertical to the common plane and to a V-groove vertical plane which includes the base line of a V-shaped groove is vertical to the common plane, and a reflective lateral face containing the base line of the v-shaped groove, and the V-groove vertical plane, does not form a constant angle in the reflective lateral face but the lateral face forms a curved and/or multiple surface. A base line constituting any directional V-shaped groove in retroreflective element pairs is a nonlinear base line which does not form a linear trajectory and the reflective lateral face formed of the V-shaped groove forms a curved and/or multiple surface. | 07-01-2010 |
20100110545 | RETROREFLECTIVE ARTICLE - A retroreflective object having a retroreflective clement layer in which a large number of cube corner retroreflective elements of total internal reflection type are disposed. In the back surface of the retroreflective element layer, an optical characteristic adjusting layer is partially provided, and in the back surface of the optical characteristic adjusting layer, an air layer is provided. With the invention, an optical characteristic adjusting layer for adjusting a hue and occupant area ratio can be provided on the back surface of the retroreflective element layer of an existing object in a simple way for easy adjustment, thus enabling a retroreflective object to be manufactured at high productivity and low cost. Therefore, retroreflective objects suitable for reflective plates for traffic related signs such as a traffic sign, a regulation sign, an information sign, and a construction work sign, commercial sings, and reflected-light sensors for visible light, laser beam, or infrared light can be manufactured effectively with use of existing products. | 05-06-2010 |
