An optical fiber fusion splicer includes a discharge unit for producing an electric discharge to fusion splice optical fibers and a pressure sensor for producing a pressure detection signal representing the surrounding atmospheric pressure. In response to the pressure detection signal the discharge is controlled by a control unit so that a substantially optimum discharge current for the fusion splicing is provided to the discharge unit. The discharge control unit includes an adjusting unit for p...

A rapidly pulsed nuclear fusion reaction system including a firing chamber into which synchronized opposing beams of ionized gas such as deuterium/tritium are injected in the form of ion pulses which are adapted to collide at the mid point of the chamber. The pulsed ion beams are fed through respective orifices across which is applied a relatively high DC voltage. External to the firing chamber is means for generating a pulsed magnetic field interiorally of the chamber along the ion travel path ...

A process for performing intra-oral orthodontic practices including an electric fusion instrument that can be operated to weld inside the oral cavity.

A fusion system is provided whereby material in comminuted form or the like may be automatically fused under conditions which provide a homogeneously fused sample which then may be analyzed by analytical techniques to determine content of the material. The apparatus for carrying out the fusion provides control of the initial heating time, fusion time, and cooling time, as well as controlling the mixing or blending of the sample material during the fusion to ensure the homogenuity of the mixture.

A gold alloy for use in a dental restoration which does not cause discoloration and greening of dental porcelain after being cast and having a porcelain jacket fired thereon. The gold alloy also produces extremely clean castings. The alloy is 30-50% gold, 30-50% palladium, 5-30% silver, 0.01-5% of at least one element from silicon, boron, germanium and mixtures thereof and 0.01-1.0% of ruthenium. Other elements are included for strength.

A poloidal divertor for a toroidal plasma column ring having a set of poloidal coils co-axial with the plasma ring for providing a space for a thick shielding blanket close to the plasma along the entire length of the plasma ring cross section and all the way around the axis of rotation of the plasma ring. The poloidal coils of this invention also provide a stagnation point on the inside of the toroidal plasma column ring, gently curving field lines for vertical stability, an initial plasma curr...

This invention consists of a system which generates clean inexpensive electrical power by fusing isotopes of hydrogen or other lightweight material. Not unlike a cyclotron "turned wrong-side out" ions are accelerated each time they cross a gap between two perforated "bowls" across which is placed high frequency-high voltage. Accelerated ions leave the bowls and go into magnetic gaps or mirror-tubes arranged radially thereon and are generally reflected back through the center of the system betwee...

This invention relates to a nuclear fusion power plant for producing useful electrical energy by nuclear combustion of deuterium and lithium to helium. A large concentric plate capacitor is discharged rapidly through a mass of molten LiD.sub.1-x T.sub.x (O<X<1) that is situated at its center. Before this discharge, a conducting path had been thermally preformed between the electrodes by an ac current pulse. The high-temperature, high-pressure plasma is confined by the LiD liquid in a narro...

A process for fusion-bonding of resins, which comprises applying a layer of thermoplastic resin having a light transmittance lower than 20% and a melting point of 40.degree. to 250.degree. C. to a substrate and fusion-bonding the resin layer to the substrate by emission energy of a flash discharge lamp. The electric input energy J (joule) of the flash discharge lamp is controlled relative to the weight of the resin layer.

A process for fusion-bonding of resins, which comprises applying a thermoplastic resin having a melting point of 40.degree. to 300.degree. C. to a paper and fusion-bonding the resin to the paper by emission energy of a flash discharge lamp. The energy emission density of the flask discharge lamp is controlled relative to an electric input energy necessary for irradiation, the inner diameter of the bulb of the flash discharge lamp, the flash discharge passage length, and the pulse width.
