摘要:
A phosphor layer is provided on a back glass substrate placed opposite a front glass substrate with a discharge space in between, and formed in a double-layer structure consisting of a first phosphor layer and a second phosphor layer having its surface covered by the first phosphor layer. The first phosphor layer is formed of materials that permit the passing-through of a xenon molecular beam but absorb a xenon resonance line in the vacuum ultraviolet light generated from a discharge gas by means of a discharge, and have a higher resistance to the resonance line than that of the second phosphor layer. The second phosphor layer is formed of materials that have, as compared with the first phosphor layer, a higher light-emission brightness based on the xenon molecular beam in the vacuum ultraviolet light generated from the discharge gas by means of the discharge.
摘要:
A discharge is initiated in a discharge space defined between the front glass substrate and the back glass substrate, whereby vacuum ultraviolet light is generated from a discharge gas filling the discharge space and excite phosphor layers. Each of the phosphor layers is formed of a firs phosphor having a resistance to an Xe resonance line, and absorbing the Xe resonance line and ultraviolet light in a longer wavelength range than the Xe resonance line and the Xe molecular beam but allowing the Xe molecular beam to pass through, and a second phosphor absorbing the Xe resonance line and the Xe molecular beam and generating ultraviolet light in a longer wavelength range than the Xe resonance line and the Xe molecular beam.

An edge exposure unit includes a projector, a projector holding unit, a substrate rotating unit, an outer edge detecting unit and a surface inspection processing unit. Each component of the projector holding unit operates to move the projector in an X direction and a Y direction. The projector irradiates a peripheral portion of a substrate with light transmitted from a light source for exposure through a light guide. Edge sampling processing is performed based on distribution of an amount of light received in a CCD line sensor of the outer edge detecting unit. Surface inspection processing is performed based on distribution of an amount of light received in a CCD line sensor of the surface inspection processing unit.

A booster circuit generates a boosted output by boosting a low voltage output supplied as a target to be boosted and feeds back a part of the boosted output, an output by the booster circuit itself, to the booster circuit as operation energy. An auxiliary booster circuit outputs start-up energy generated based on a low voltage output to the booster circuit as start-up energy that is necessary for starting up the booster circuit.

An automatic teller machine includes a customer operating touch panel 2 having a plurality of operating keys which are touched for actuation. Guide icons 3 which are embossed to represent the icons of the operating keys are provided in the periphery of the customer operating touch panel at positions corresponding to said plurality of operating keys.
摘要:
A method and apparatus for exposing a substrate to light perform the steps of inputting position data of a peripheral region along an outline of a chip region on a substrate, which has been placed on a spin chuck, detecting a reference position at an outer edge of the substrate inputting axial directions of the position data and aligning axial directions of an orthogonal shifting mechanism. Based on the position data inputted, light of an irradiator is shifted along the peripheral region to expose the peripheral region in a staggered way along the outline of the chip region. The method and apparatus may also perform the steps of inputting a shape of the chip region on the substrate as image information, deriving position data of the peripheral region along the outline of the chip region from the image information, and exposing the peripheral region to light based on the position data derived. The method and apparatus may also perform the steps of inputting shape information of the substrate, the chip region, and an area around a crossing point of scribe lines in the chip region on the substrate as image information, computing the positions of the peripheral region from the image information and the shape information of the substrate and the chip region; and exposing the peripheral region to light based on the positions of the computed peripheral region.
