Abstract: A power plant for producing electricity utilizing the buoyancy of a liquid. A first and second expandable chamber are each place in a liquid filled shaft are coupled together with a cable so that when one of the expandable chambers is raised, the other one is lowered. The cable is couple to a pulley for turning a generator for producing electricity. An electrode and electrolyte are placed within each expandable chamber for generating heat and steam to expand the expandable chamber when the expandable chamber is at the bottom of the liquid filed shaft. The increased volume of the expandable chamber causes it to rise in the liquid filled shaft at the same time as the other expandable chamber is reduced in volume and caused to be lowered into the other liquid filed shaft. A valve in the expandable chamber releases the steam causing the volume of the expandable chamber to be reduced. The released steam may be used to power a turbine or enter a heat exchanger.

Abstract: A catadioptric projection optical system for use in photolithography used in manufacturing semiconductors having a quarter waveplate following a reticle and multiple aspheric surfaces and calcium fluoride lens elements. A quarter waveplate following the reticle eliminates asymmetry in reticle diffraction caused by polarized illumination. The use of additional aspheric surfaces reduces the number of lens elements and aids in reducing aberrations. Calcium fluoride elements are used in the lens group adjacent the wafer to help minimize compaction. In one embodiment, only calcium fluoride material is used. The present invention provides a projection optics system having a numerical aperture of 0.75 for use with wavelengths in the 248, 193, and 157 nanometer range. The object and image locations are separated by a predetermined distance, making possible retrofitting of older optical systems.

Abstract: A fastener feeding mechanism for a power actuated gun (10, 310, 410, 510) having a track (16, 316, 416, 516) for holding a plurality of fasteners (18, 318, 636). Fasteners are biased by a spring (32, 372, 672) down the track towards a holding or latch mechanism (22, 322, 422, 522). The holding or latch mechanism has a retractable latch. The holding or latch mechanism holds a fastener in a predetermined position to be driven into a substrate. A guide (14, 314, 414, 514) attached to a barrel (12, 312, 412, 512) of a power actuated gun guides the barrel permitting the barrel to be advanced for firing and driving the fastener. After firing a bias on the guide causes the barrel to be retracted for the positioning of another fastener to be driven. The present invention greatly facilitates the driving of fasteners having a plate, and permits the driving of fasteners quickly resulting in more efficient and therefore less costly construction.

Abstract: An insert for a firearm having a large diameter portion extending a predetermined axial distance into a breech and a small diameter portion adapted to fit within the chamber of a barrel. The predetermined axial length of the larger diameter portion has a length long enough to prevent a hammer from striking a firing pin and short enough so that the hammer can be cocked and released by the trigger. In an embodiment a lock means prevents the insert from being removed from the firearm without authority. In another embodiment, a handle is used as a flag or for cocking. The firearm may be dry-fired for practice purposes without striking the firing pin. The insert is also readily visible so that a quick inspection of the firearm will confirm that the firearm is in a safe state. The present invention may be made to accommodate many different firearms and may also be used to safely dry-fire a firearm. The insert of the present invention also provides more realistic dry firing, greatly improving the effect of training.

Abstract: An alignment sensor having a fixed reference grating and a movable wafer grating receiving electromagnetic radiation from a coherent illumination source. The illumination source is split into two beams by a beamsplitter. One beam is directed to a fixed reference grating and the diffracted orders are collected. The other beam from the beamsplitter is directed to a movable wafer grating. The diffracted orders from the movable wafer grating are collected and caused to interfere with the diffracted orders from the fixed reference grating, causing a phase shift indicative of the wafer movement or misalignment with respect to the fixed reference grating. Multiple channels having discrete wavelengths or colors are used to optimize detection and alignment irrespective of wafer processing variables. A polarization fixture on the illumination source and a central polarizing portion on the beamsplitter is used to provide contrast optimization, or alternately a latent image metrology mode.

Abstract: A robust coiled filament electrode for a fluorescent lamp used in high vibration environments. A cylindrical mandrel is placed within coils in each end of a coiled filament electrode. The mandrel and the coiled filament electrode are held by a mounting post. The mounting post is bent over and crimped, holding the mandrel and coiled filament electrode. The mandrel extends inward between the two mounting posts, providing support for the coiled filament electrodes. The coiled filament electrode may be made by method or process of chemically dissolving selected portions of a mandrel. Lamp life is extended, as well as the variance between lamp life is substantially reduced. The present invention is particularly applicable to applications in avionics.

Abstract: A stereo camera capable of photographing a stereo picture maintaining an optimum stereo effect. Right and left lens boards 42R, 42L of a stereo camera 41 are coupled to a camera body 46 via upper and lower two sets of parallel links 47. Parallel grooves 45L, 45R are formed in the lateral direction in the inner portions of the lens boards 42L, 42R, and with which a circular eccentric cam 43 is engaged. When the shaft mounting the cam 43 is turned, the right and left lens boards 42R and 42L move in parallel describing circular loci, making it possible to automatically adjust the focal point as well as the distance between the optical axes of the lenses, which is important for accomplishing a stereo effect.
