摘要： A ferromagnetic iron alloy powder for a magnetic recording medium is composed of acicular iron-base particles of an average major axis length (X) of not less than 20 nm and not greater than 80 nm and have oxygen content of not less than 15 wt % and coercive force (Hc) of not less than [0.0036 X3−1.1 X2+110 X−1390 (Oe)] (where X is average major axis length expressed in nm). The ferromagnetic iron alloy powder is obtained by reacting metal powder composed of acicular iron-base particles having an average major axis length of not less than 20 nm and not greater than 80 nm with pure water in substantial absence of oxygen to form a metal oxide film on the particle surfaces. Optionally, the particles can be reacted with a weak oxidizing gas by a wet or dry method.

摘要： An apparatus for manufacturing a lens sheet comprises an application device, a substrate supply device, a pressing device and an irradiation device. The application device applies ionizing radiation curing type resin in the form of liquid on the upper surface of a forming die for a lens sheet to form an uncured resin body on the upper surface of the forming die. The substrate supply device places a substrate on the uncured resin body. The pressing device presses the substrate against the uncured resin body to flatten the uncured resin body, so as to form a uncured resin layer, while spreading the uncured resin body to an outside periphery of the forming die. The irradiation device irradiates ionizing radiation on the uncured resin layer through the substrate to cure the uncured resin layer.

摘要： A method for peeling a lens sheet having two pairs of opposite portions from a forming mold comprises the first to third peeling steps. The first peeling step is to pull up a pair of opposite portions of a lens sheet, which is formed on a forming mold, to peel partially the lens sheet from the forming mold. The second peeling step is to pull up the other pair of opposite portions of the lens sheet to peel partially the lens sheet from the forming mold. The third peeling step is to pull up further the two pairs of opposite portions to peel entirely the lens sheet from the forming mold.

摘要： Provided is a taping machine which enables shortening the time length for bonding to each other a Fresnel lens sheet and a lenticular lens sheet and for the inspection process as well as reducing the space occupied by apparatuses used for the both processes. The taping machine includes a table part that has placed thereon a Fresnel lens sheet and a lenticular lens sheet with the end surfaces thereof being regularly arranged and superposed over upon the other, and a tape-applying mechanism that bonds the end surfaces to each other by means of a tape. The table part has a black-colored opaque plate on which a transparent plate is mounted.
