Abstract:
A film removing apparatus comprises a substrate holding portion which holds a substrate having a coating film, a laser source which locally irradiates an alignment mark position of the substrate on the substrate holding portion with laser beams, and partially abrades the coating film from the substrate, a fluid supply mechanism including a main nozzle which supplies a predetermined fluid to the alignment mark position, a recovery mechanism having a suction opening which sucks the predetermined fluid supplied to the alignment mark position together with an abraded film component on the substrate, and a guide member which guides the predetermined fluid emitted from the main nozzle to the alignment mark position, and guides the predetermined fluid and the abraded film component to the suction opening of the recovery mechanism so as not to be diffused/leaked around the alignment mark position.
Abstract:
A process for incorporating a long persistent phosphor into a fabric material which occurs by firing a phosphor whithin a crucible, then grinding the resulting aggregate into a phosphor particulate of specified size, encapsulating the phosphor particulate witthin a water impervious coating material and then applying a specified ratio by weight of the encapsulated phosphor particulates into the fabric material. Further, a fibrous product is described incorporating encapsulated long persistent phosphor particles.

Abstract:
Disclosed is an optical recording medium, comprising a polymer alloy forming a phase-separated domain structure of a coating object, and a volatile substance interacting with the polymer alloy. The volatile substance in a vapor state is deposited on the surface of specific phase-separated domain, and dispersedly infiltrated into the phase-separated domain. The phase-separated domain and the volatile substance chemically interact with each other. The optical recording medium is operable to perform optical recording by utilizing change in the transmittance, reflectance, refractive index or surface potential thereof in response to irradiation of ultraviolet light, visible light, or infrared light from outside. The present invention can provide an optical recording medium suitable for high-density recording in a wide wavelength range.

Abstract:
An external mix air assisted spray nozzle assembly having a nozzle body, and an air cap for a directing pressurized air streams on a discharging liquid stream external to the liquid discharge orifice of the nozzle assembly for atomizing and forming the liquid into the desired spray pattern. The air cap includes an upstream internal air chamber, an external, downstream liquid discharge and mixing chamber, and a central opening coaxial with the liquid discharge orifice communicating between the upstream and downstream chambers. The air cap further includes a plurality of angled pressurized air discharge passages which communicate with an annular plenum of the air chamber disposed in surrounding relation to the central opening for enabling substantially uniform particle breakdown and distribution at lower air pressures than heretofore possible.
Abstract:
Multilayer-film mirrors are disclosed that exhibit high reflectivity to incident X-radiation independently of the angle of incidence and without significantly compromising optical performance. Also disclosed are X-ray optical systems and microlithography apparatus comprising such mirrors. In an embodiment a multilayer-film mirror is formed by alternately laminating Mo layers (a material in which the difference between its refractive index in the weak X-ray band and its refractive index in a vacuum is great) and Si layers (a material in which said difference is small) on a substrate. The ratio (null) of the thickness of the Mo layer to the total of the thickness of the Mo layer and the thickness of the Si layer has a distribution based on the distribution of angles of incidence of X-radiation on the mirror surface. By providing null with a distribution that corresponds with the distribution of the angles of incidence in the mirror surface, maximum reflectivity can be obtained at the angles of incidence at various points within the mirror surface. Because there is no need to change the period length in this case, there is no deterioration in the optical performance of the mirror.
Abstract:
A vacuum deposition process for depositing powdered phosphor on fiber optic face plates, such as the output fiber optic window of gated image intensifiers. The process involves resistive heating vacuum deposition of a powdered phosphor, such as Zn, CD, (S) to a thickness of 7900 Angstroms, for example, after which it is annealed which promotes a columnar growth and makes the phosphor efficient. The thus annealed phosphor can then be directly overcoated with aluminum of a thinner coating than over a powdered phosphor produced by prior known methods due to the smoother surface produced by this process.

A powder spraycoating apparatus comprising at least one compressed-air outlet (8) connected to a source (14) of compressed air from which it receives compressed air (15) at such a rate and such pressure that the compressed air at the compressed-air outlet (8) shall detach the powder's boundary layer from the powder duct (4) and shall concentrate the powder flow toward the radial flow center and make it swirl, at a site near the downstream end (6) of the powder duct (4).
Abstract:
A plurality of unconventional negative tribo-charging materials are described for use as the powder contact surfaces in tribocharging and corona powder spray guns, gun components, and powder delivery system components. The invention also provides a short barrel tribo-charging powder spray gun having an interchangeable powder contact insert and nozzle, with turbulence inducing air jets. The invention further provides novel tribocharging and corona gun designs. Improved powder coating systems are made possible wherein, for example, negative tribo guns can be utilized with negative corona guns to coat different parts of the same workpiece in a powder coating system. Also provided is an inside-out configuration in which pressurized air directs powder coating material outward towards a charging surface. Additional configurations provide air jet induced tribocharging and conventional tribocharging portions combined in a single gun.
