Abstract:
A light-transmissive support disk supports a tube for attracting an LED chip, and a light-transmissive electrically conductive film is disposed on the support base. The LED chip is electrically connected to a negative terminal of a DC power supply by the light-transmissive electrically conductive film. An imaging unit is disposed coaxially with the tube and has a CCD camera for capturing an image of a light-emitting state of the LED chip via the support disk and a cover member when the LED chip attracted by the tube emits light. The light-emitting center of the LED chip can be detected accurately, and bonded easily and highly accurately on a board at a desired position thereon.
Abstract:
A method and a device for repelling pit vipers (rattlesnakes, copperheads, water moccasins) and boids (pythons, anacondas, boa constrictors) are disclosed whereby the snakes are irradiated with IR radiation having an appropriate wavelength and intensity to stimulate the IR-receptors of the snakes, thereby “jamming” the IR-receptors and/or producing an inimical electromagnetic environment that the snakes cannot tolerate.

Abstract:
Cleaning apparatus using ultraviolet rays comprises a cleaning head having a transparent body, a light source and a light guide member. capable of transmitting said ultraviolet rays from said light source to said transparent body. The transparent body is capable of transmitting ultraviolet rays. The light source is capable of emitting the ultraviolet rays. The light guide member is capable of transmitting the ultraviolet rays from the light source to the transparent body. The cleaning head may have preferably the transparent body and a group of brushes in which the group of brushes are supported by the transparent body. The cleaning apparatus may be applied for a vacuum cleaner.
Abstract:
The spherical aberration of an optical beam is determined by focusing the beam, and dividing its cross-section in at least two concentric zones. The sub-beams passing through the zones are focused each on a focus-detection system. The distance between the positions of the two foci is a measure for the spherical aberration present in the beam.
Abstract:
Multi-spectral products for simulating military and civilian objects or for identification and marking of those objects. The multi-spectral products are provided with sandwiched structure having a first layer and a second layer, overlapping with the first layer. The first layer is patterned by an image of the object in question, which is recognizable in visual specter. The second layer is made of material, which is capable of producing thermal contrast detectable in infrared specter. The second layer produces thermal contrast without using dedicated source of energy and its configuration corresponds to thermal signature cue of the object.
Abstract:
An adaptive optics system configured as an optical phase front measurement system which provides for relatively high resolution sampling as in holographic techniques but without the need for a reference beam. The optical phase front measurement system includes one or more lenses and a spatial light modulator positioned at the focal plane of the lenses and a camera which enables the phase front to be determined from intensity snapshots. The phase front measurement system allows for relatively long range applications with relatively relaxed criteria for the coherence length of the laser beam and the Doppler shift. As such, the system is suitable for a wide variety of applications including astronomy, long range imaging, imaging through a turbulent medium, space communications, distant target illumination and laser pointing stabilization.
Abstract:
In a particle projection lithography system, an alignment system is used to determine alignment parameters to measure the position and shape of an optical image of a pattern of structures formed in a mask and imaged onto a target by means of a broad particle beam, by means of an apparatus with a plurality of alignment marks adapted to produce secondary radiation upon irradiation with radiation of said particle beam. In order to allow for a variation of the alignment parameters along the optical axis, the alignment marks are positioned outside the aperture of the alignment system for the part of the beam that generates said optical image, arranged at positions to coincide with particle reference beams projected through reference beam forming structures provided on the mask while said optical image is projected onto the target, and situated on at least two different levels over the target as seen along the directions of the respective reference beams.
Abstract:
A lithography system for processing a substrate is disclosed. The lithography system includes a stage for moving the substrate relative to a beam. The lithography system further includes a chuck for securely holding the substrate during stage movement. The lithography system additionally includes a support assembly for holding the chuck in a fixed position relative to the stage while accommodating for deformations in either the chuck or the stage during processing so as to precisely locate the substrate relative to the stage and to reduce external stresses that cause substrate distortions.
Abstract:
A UV light utilizing an angled dichroic cold mirror reflector to selectively direct UV light out of a window on the side of the light housing while transmitting visible and infrared light out a window in the end of the housing to eliminate heat. The light may be used both as a flashlight and a black light for UV inspection. A removable cap can be placed over the end window to block visible light.
Abstract:
A powdered far-infrared radiator includes a quartz schist pulverized into a powder having a grain diameter not exceeding 6 &mgr;m and heat-treating the powder at or above 200° C. The quartz schist radiates far-infrared rays at an ordinary temperature.
