  • Publication number: 20060139758
    Abstract: A microlens array sheet includes a light-shielding base having a first surface and a second surface opposite to the first surface and a microlens array attached to the first surface of the light-shielding base, the array having a plurality of microlens. The light-shielding base has a plurality of apertures that correspond to the microlenses. Each aperture has a conical trapezoid-like shape in which a size of each aperture on the first surface side is larger than another size of each aperture on the second surface side. Instead of the light-shielding base, the microlens array sheet may include a transparent base having a first surface and a second surface opposite to the first surface and a light-shielding layer, having a third surface and a fourth surface opposite to the third surface, provided on the second surface of the transparent base.

  • Patent number: 6652998
    Abstract: In a first forming process, by injecting a predetermined amount of oxygen gas, magnetic metal vapor 7a is deposited as a nonmagnetic underlayer on a base film F wound on one film winding roll 3B while advancing the base film F in a reverse direction (second direction) toward another film winding roll 3A along a cooling can roll 5 from a minimum incidence angle side to a maximum incidence angle side of an incidence angle controlling mask 9. In a second forming process, by injecting a extremely smaller amount of oxygen gas than in the first forming process, magnetic metal vapor 7a is deposited as a magnetic layer over the nonmagnetic underlayer while advancing the base film deposited with the nonmagnetic underlayer wound on the other film winding roll 3A in a forward direction (first direction) toward the film winding roll 3B along the cooling can roll 5 from the maximum incidence angle side to the minimum incidence angle side of the incidence angle controlling mask 9.

  • Publication number: 20020045543
    Abstract: Disclosed are alumina particles with a dispersed noble metal. The alumina particles are hollow-structured alumina particles which comprise alumina as a major component of the matrix, and in which at least one noble metal is dispersed in the alumina matrix and/or on the surface of the alumina particles with a dispersion degree of 10% or more when being measured by the CO adsorption method. The noble metal dispersion degree is so high that the alumina particles are suitable for making a catalyst. The resulting catalyst exhibits the purifying performance, which hardly differs before and after a high temperature durability test, and is extremely good in terms of the durability.

  • Patent number: 6254410
    Abstract: Described is a connector in which a plug can be pulled out of a receptacle without producing stress in the connector itself or a circuit board on which the connector is mounted. The plug is inserted into the receptacle so that the side wall of the plug makes contact with the interior wall of the receptacle. When the plug and the receptacle are coupled, a fitting space is formed therebetween. When compressed air is injected into this fitting space, the plug will be pushed up by a rise in the air pressure and therefore the plug can be pulled out of the receptacle. The use of air pressure in the fitting space to pull out the plug is advantageous because it can be implemented without producing biased stress in the plug or the receptacle.
