Abstract: A candy holding device which is used to hold a piece of candy such as a sucker in a covering to protect the candy from dirt, etc. The cover is formed in two halves which in a folded condition encloses the candy. The two halves of the cover are connected at one end on swivel drums so that in use, the half covers are pulled apart and rotated from an upper position to a lower position. As the two half covers are rotated to the lower position the two halves are rotated about the swivel drums 180 degrees so that the two halves can be secured together to form a handle. In order to protect any candy that is left, the handles are moved upwardly and rotated 180 degrees to enclose the candy within the two half covers.

Abstract: A basketball game which can be played in bed by a sick person for exercise. The basketball hoop is secured to the backboard by use of integral end supports which fit into spaced spring-like fingers. The back of the hoop has a downwardly extending integral support which prevents the hoop from falling below a horizontal position perpendicular to the backboard. The hoop has a slot in the front and the net is slit so that a ball attached to a line can pass through the hoop and the line can pass through the slot and slit so that the player can retrieve the ball. The backboard is supported by a base which has frontward extending pieces that will fit between a mattress and spring for supporting the backboard and hoop in an upright position.

Abstract: A game in which one player throws a Bola Ball in such a manner that another player has difficulty in catching the Bola Ball. This can be achieved by placing a flexible cord of the Bola Ball in different positions on the stick. The player can then sling, fling, lob, twirl, etc. the Bola Ball at the other player depending on the position on the stick. After the other player has tried to catch the Bola Ball it's his/her turn to throw it back in any manner he/she wishes.

Abstract: A system and method of rapidly obtaining quantitative information as to the elemental constituents of coal, particularly the oxygen and sulfer content thereof. The system makes use of the photonuclear interaction to produce the desired radioactivity in the coal constituents. The above mentioned interaction is induced by high energy x-rays from a suitable electron accelerator. The induced radioactivity manifests itself by the emission of characteristic gamma rays among other things. These gamma rays are detected by conventional energy sensitive gamma-ray detectors such as germanium or sodium iodide crystals. The resultant signals are sorted and analyzed to provide the desired information.

Abstract: A method of improving the signal-to-noise ratio (dynamic range) in integrated optical spectrum analyzers. An integrated optical spectrum analyzer is formed with a lithium niobate (LiNbO.sub.3) substrate in its usual manner. Ions such as argon or hydrogen are implanted in the bottom and sides of the LiNbO.sub.3 which causes the substrate to absorb light at the wavelength of interest. The ion-implanted bottom and sides provide absorption with very little reflectivity and the amount of absorption is proportional to the effect of the ion and the time period of implantation. The bottom and sides behave as optical sinks, rather than as reflection or scattering centers.

Abstract: A method of achieving inversion in solid-state rare-earth materials for blue-green laser operation. A XeF excimer laser is used to pump a matching transition in divalent ytterbium in a host material. The host material is co-doped with a trivalent ion such as praseodymium (Pr.sup.3+) so that energy transfer to the trivalent ion will take place. Laser action is then from the Pr.sup.3+ ion. Alternative matching absorption transitions also occur in the trivalent rare-earth ions of Tb, Dy, Ho, and Nd.

Abstract: A method for accurately determining the compensation density of n-type naw-gap semiconductors. A semiconductor sample is irradiated with laser pulses of a particular density and pulse width for a particular time length with the sample maintained at a low temperature to generate photo-excited carriers within the semiconductor sample. Photons of energy less than the energy gap, E.sub.g, but greater than, E.sub.g /2, generate carriers uniformly throughout the semiconductor via the nonlinear mechanism of two-photon absorption. Photo-Hall measurements are made on the semiconductor sample during and after the laser pulse to determine the mobility, .mu., and carrier density, n, as a function of time using suitable equipment such as a computer controlled digital processing oscilloscope to display the curves. The curves displayed by the oscilloscope are compared with previously calculated curves to obtain a match and thereby determine the quality of the sample.

Abstract: A new class of solid-state laser which employs self-pumping from internal laser transitions to achieve inversion in other transitions. A LiYF.sub.4 laser having an activator of trivalent holmium is pumped by a standard flashlamp or by a doubled Nd laser to populate the .sup.5 S.sub.2 manifold. Inversion is achieved between .sup.5 S.sub.2 and .sup.5 I.sub.5 at 1.4 .mu.m. Employing appropriate mirrors, inversion is then produced between .sup.5 I.sub.5 and .sup.5 I.sub.7 at 1.7 .mu.m. Finally inversion is obtained between .sup.5 I.sub.7 and .sup.5 I.sub.8 at 2.06 .mu.m.

Abstract: A magnetic fluid transducer for producing a low-frequency sound field in a fluid medium. The device comprises a non-magnetic cylindrical housing with end windows. The housing is surrounded by a magnetic-field-generator means and contains a magnetic fluid within the housing. The magnetic field penetrates the housing and interacts with the magnetic fluid. A body force is developed within the fluid which produces an internal pressure in local regions defined by the lines of magnetic flux. This internal pressure is transmitted by an acoustic transmitting medium to the surrounding fluid as a sound pressure level.

Abstract: An optical system which detects acoustical signals in a fluid medium such as seawater. The acoustical sensor assembly includes an acoustical sensor which is formed by two optical fibers which have different sensitivities to acoustical signals and are connected with the optical radiation conductor or conductors by use of an optical coupler which couples optical radiation into each of the optical fibers of the acoustical sensor. Since the optical fibers of the acoustical sensor have different acoustical sensitivities to acoustical signals, the phase of the optical radiation transmitted through each optical fiber of the acoustical sensor will change differently due to acoustical signals incident thereon. The optical radiation from the optical fibers of the acoustical sensor is directed back through an optical fiber to a photodetector. The photodetector produces a modulated output signal in accordance with the acoustical energy detected.

Abstract: A method of forming a single, reliable n.sup.+ contact for discrete GaAs devices. A film of p-type Ge is deposited uniformly over the surface of a n-type GaAs substrate. Ions of phosphorous or arsenic are implanted to 5.times.10.sup.18 ions/cc at a depth of 1500 A. The ends and the sides of the substrate and Ge layer are capped by a CVD oxide and annealed at 450.degree.-500.degree. C. for about one hour. This process over-compensates the initial p-type layers which results in the Ge layer becoming n.sup.+. The oxide is removed by an etch process and the n.sup.+ Ge is etched to form two separate contact sections of n.sup.+ Ge. The n.sup.+ Ge is then metalized to form ohmic contacts by use of NiAu. A CVD oxide overcoat may again be applied and annealed at about 500.degree. C. to drive a shallow 200-500 A, n.sup.+ germanium diffusion into the substrate.
