Abstract: A 3-dimensional image display method stores in memory a plurality of interference patterns in bit format, and recursively projects orthoscopic real or virtual holographic images having both horizontal and vertical parallaxes. A 3-dimensional image display system has a cathode-ray tube comprising a screen made of cathodochromic material, an electron beam unit, and a laser unit.      The electron beam unit comprises an electron gun and an electron lens for writing the interference pattern on the screen by a scanning electron beam. The laser unit comprises a point source of coherent light and an optical lens for illuminating the screen by an expanded light beam, and for erasing the interference pattern on the screen. This invention relates to 3-dimensional image display method and system, and the principal use of the invention is for dynamic holograms, and for 3-dimensional computer and television video monitors.

Abstract: A signal transmission fuse is made of a tube (36) which encases a support ta pe (14) having a reactive coating (18') which is adhered to one side of the tape by a binder. A method of making the signal transmission fuse includes depositing on the support tape (14) a reactive paint (18) including a binder, which paint dries to form a reactive coating (18'). The coated support tape (14') is then folded, i.e., formed into a channel configuration, to provide an inner concave side of the tape o n which the reactive coating (18') has been disposed. The coated support tape is then enclosed, e.g., within an extruded plastic tube (36). O ne side of the support tape may be made of a first material (14a) to which the reactive coating adheres, and a second side may be made of a second material (14b) which bonds or adheres to the inner surface (36a) of the plastic tube (36) enclosing the coated support tape (14'). The binder causes even high loadings of the reactive coating (18') to adhere to the coated support tape (14') to prevent reactive materia l migration. The support tape also shields the reactive material from the hot, freshly extruded surrounding plastic tube (36) during manufacture.

Abstract: A pilot operated control valve has a body with an inlet and an outlet. A main valve poppet is movable within the body to selectively control flow of fluid between the inlet and outlet. The main valve poppet has a flexible diaphragm with a pilot passage therethrough which is opened and closed by movement of a pilot poppet. The diaphragm flexes due to a pressure differential that acts on the pilot poppet, which flexing compensates for adverse effects that the pressure differential has on the operation of the pilot poppet.

Abstract: At the time of vehicle start-up from the state of engine stopping, a hydraulic oil pressure (PSC) in a starting clutch (7) sometimes overshoots beyond a creeping pressure as a result of a rise in the hydraulic oil pressure in the hydraulic circuit, resulting in shocks. A hydraulic oil pressure command value (PSCCMD) to a linear solenoid valve (153) which controls the starting clutch pressure (PSC) is made smaller than the creeping pressure until the point of time at which the rise in the hydraulic oil pressure in the hydraulic circuit (= the point of time at which a condition of F2 = 1 is satisfied). Once a discrimination of a rise in the hydraulic oil pressure has been made, the command value is made higher than the creeping pressure for a predetermined period of time (i.e., for the period of YTM3 - YTM3B1), and is thereafter made to the creeping pressure.

Abstract: To provide a receiver not requiring any large circuit.

Abstract: In producing an approximation of an original speech signal from encoded information about the original speech signal, current parameters (EnPar(i)) associated with a current segment of the original speech signal are determined from the encoded information. Reproduction of a noise component of the original speech signal is improved by using at least one of the current parameters and corresponding previous parameters respectively associated with previous segments of the original speech signal (31, 37, 39) to produce a modified parameter (EnPar(i)mod). The modified parameter is then used (25, 40) to produce an approximation of the current segment of the original speech signal.

Abstract: A safety-lock mechanism for use with a multi-position window having a stationary window frame, a sash window frame positioned within the stationary window frame and selectively pivotable out of the stationary window frame about a vertical axis and a horizontal axis, and a drive train positioned between the sash window frame and the stationary window frame, the drive train being moveable between at least a first position which enables the sash window frame to be pivoted about the horizontal axis and a second position which enables the sash window frame to be pivoted about the vertical axis. The safety-lock mechanism includes a spring--biased pin provided on the sash window frame. The pin has a proximal end, a distal end, a locked position and an unlocked position, and is normally biased in the locked position. An aperture is provided within the drive train and is configured to receive the proximal end of the pin. In the locked position, the proximal end of the pin extends into the aperture so as to prevent movement of the drive train from the first position into the second position. When the pin is placed in the unlocked position, the drive train is capable of being moved from the first position into the second position, thereby allowing the sash window frame to be pivoted about the vertical axis.

Abstract: A novel rolling cone rock bit includes a plurality of PDC or other cutters mounted to the leg of the drill bit and positioned to cut the troublesome corner of the bottomhole. The plurality of cutters may be the primary cutting component at gage diameter, or may be redundant to gage teeth on a rolling cutter that cut to gage diameter. Consequently, the occurrence of undergage drilling from the wear and failure of the gage row on a rolling cutter is lessened. Another inventive feature is the inclusion of a mud ramp that creates a large junk slot from the borehole bottom up the drill bit. The resulting pumping action of the drill bit ramp speeds up the removal of chips or drilling cuttings from the bottom of the borehole, reduces the level of hydrostatic pressure at the bottom of the borehole and minimizes the wearing effect of cone inserts regrinding damaging drill cuttings.

Abstract: The armature is fabricated from pre-machined copper sheet metal parts with an electrical conductor pattern of nu-merous axially extending conductive bands. These precision machined sheet metal parts are cold rolled to form two work hardened cylinders, each cylinder having a complimentary pattern of electrically conductive bands creating a half-electric circuit. The two cold rolled metal cylinders are sized such that the smaller diameter inner cylinder fits inside the larger diameter outer cylinder. The surface of the inner cold rolled cylinder is over-wrapped with fiber strands, woven in several layers to provide physical spacing and electrical insulation. The fiber wrapped inner cylinder is placed inside the larger outer cylinder radially oriented to ensure that an electrical circuit is created by welding the inner and outer cylinder at the conductor tabs. The surface of this cylinder assembly is over-wrapped with fiber strands, woven in several layers and holding the two cylinders together.
