Abstract: A technique for transferring discrete areas of material, such as hot stamping foil, from a carrier onto positions spaced apart along a substrate, such as paper. The carrier is dispensed at a rate that is much less than the speed of movement of the substrate. During transfer, a segment of the carrier is moved at the same speed as the substrate while, in between such material transfers, the speed of the carrier is sharply reduced and even reversed in direction in order to maintain the average speed of this carrier segment equal to the reduced speed at which the carrier is being dispensed. This is accomplished by a shuttle mechanism that is moved by its own motor, under control of a microprocessor-based motor control system, in synchronism with the speed of the substrate and transfer operations. This significantly improves the utilization of the material on the carrier, with an improved flexibility to adapt to various substrate speeds and ease of implementation in machinery.

Abstract: An improved method and apparatus for making a dual-layer DVD disc that does not require a stamping step (typically, as part of the 2P prior art manufacturing process) during its manufacture. As proposed by Mueller, a polycarbonate substrate is molded and coated with a semireflective data layer in the usual way. A PMMA substrate is molded and coated with a fully reflective data layer. Adhesive is placed on the semireflective data layer, and the fully reflective data layer is transferred from its PMMA substrate to the polycarbonate substrate. The polycarbonate substrate thus ends up with two data layers in conformance with the DVD specifications, and the PMMA substrate can even be recycled for another use. However, instead of using a PMMA substrate that is larger than the polycarbonate substrate as proposed by Mueller, in the invention they have equal diameters. This allows conventional molding equipment to be used with no major changes.

Abstract: In order to form a holographic grating of the invention, a resist pattern having a groove depth deeper than a desired depth of diffraction grating grooves is engraved in a photoresist layer provided on an optical glass base plate by an exposure method. Then, the photoresist layer is etched by an ion beam generated by a mixed gas containing a fluorine based gas and oxygen until the photoresist layer is completely deleted. In etching the photoresist layer, the ion beam is irradiated from a direction, which is perpendicular to a grooving direction of the resist pattern and is inclined from a normal line direction of the base plate. As a result, there can be formed the holographic grating in which the diffraction grating grooves are directly engraved in the optical glass base plate. Since the diffraction grating grooves are directly engraved in the optical base plate, the photoresist layer is not peeled off as in the conventional grating, and the holographic grating of the invention has excellent durability.
