Abstract: A projection screen has a gold coated projection receiving surface that reflects light. The projection screen includes a support structure and an adhesive layer on top of the support structure. A fiber support is adhered to the support structure using the adhesive layer. A chalk and adhesive layer is applied on to the fiber support and a clay and adhesive layer is applied on to chalk and adhesive layer. A gold layer is applied to the clay and adhesive layer. A light or a portion thereof passes through each of the multiple ordered layers, including the gold layer, the clay and adhesive layer, the chalk and adhesive layer and reflects back a lustrous, iridescent image that has motion and depth qualities with transmuted color characteristics.

Abstract: A three-dimensional image projector, including a transparent display medium within which fluorescent substances are dispersed, the fluorescent substances being dispersed for performing the fluorescent light-emission of visible light by the irradiation with a laser beam of invisible light, a first-laser-beam scanning unit for scanning the inside of the transparent display medium by deflecting a first laser beam, the first laser beam being used for exciting the fluorescent substances, and a second-laser-beam scanning unit for scanning the inside of the transparent display medium by deflecting a second laser beam, the second laser beam being used for exciting the fluorescent substances, wherein a stereoscopic image is formed at a scanning intersection point of the first laser beam and the second laser beam inside the transparent display medium.

Abstract: An electron beam recording apparatus includes: a displacement detection unit including at least three displacement sensors disposed at each different angle in a radial direction of the turntable; a shape calculation unit for calculating, based on the detected displacements by the at least three displacement sensors, shape data corresponding to displacements of side surface of the turntable in the radial directions; a rotation runout computing unit for computing, based on the shape data and at least one displacement detected by the at least three displacement sensors, rotation runout of the turntable including a rotation asynchronous component and a rotation synchronous component; and a beam irradiation position adjustment unit for adjusting an irradiation position of the electron beam based on the rotation runout.

Abstract: A scanning device for scanning an original which is set at a predetermined position and has information recorded thereon comprises: a plurality of light emission members for emitting lights of different wavelengths from each other; a first reflection member having a plurality of reflection planes for selectively reflecting emitted lights of a plurality of wavelengths coming from the light emission members and an optical aid portion; a second reflection member for reflecting the lights reflected by the first reflection member to focus them on the original in a linear pattern; and an imaging optical system for focusing the lights of the linear pattern onto a sensor, whereby the sensor receives the information of the original.

Abstract: A charged particle generating device such as an ion implanter, a secondary ion mass spectrometer having a good mounting operability, a simple construction, good characteristics such as sensitivity, etc., owing to the fact that there is disposed a focusing electrode composed of the cylindrical electrodes disposed coaxially with each other, at least the inner electrode thereof having a plurality of openings.

Abstract: By using a fluorescer on the viewing surface of a visual screen and illumting the screen with ultra-violet light, a bright display of the scene is achieved when the laser scan system is operated in the negative mode to quench the fluorescence at spots on the screen that correspond to darker areas in the scene.

Abstract: Luminosity values of a structure carrying information, in particular grey scale values, are transformed into corresponding isochromates. The transformation is effected by optically imaging the information carrying structure onto a layer of liquid crystals. By this means, a thermogram corresponding to the information carrying structure produced in the layer of liquid crystals, so that the luminosity values of the structure carrying information is transformed into isotherms in the layer of liquid crystals, and the isotherms are converted into isochromates as a result of the colour/temperature behaviour of the layer of liquid crystals.

Abstract: A variable intensity fluorescent display, utilizing fluorescent segments for forming indicia when irradiated by an ultraviolet lamp, utilizes a separate source of infrared light, such as a variable intensity incandescent lamp and deep red, or infrared, filter and the like to provide quenching action in the fluorescent material in a controlled manner.

Abstract: Apparatus is disclosed for providing a visual representation of the absorption or transmission coefficients of the elements of a two dimensional matrix of elements notionally defined in a cross-sectional plane through a body. The representation is in the form of an analogue display comprising superimposed lines of information scanned on the surface of a suitable screen, the brightness of each line being indicative of the absorption suffered by penetrating radiation on traversing a respective path through said plane of the body. The orientation of each scanned line depends on the orientation of the respective path with respect to the body.
