    摘要: The present invention relates to feeding liquid oxygen from the main condenser of the upper rectifying column of an air liquefying/separating unit into a xenon condensing column. The liquid oxygen is evaporated in varying amounts in correspondence to fluctuating amounts of liquid oxygen being fed into the xenon condensing column. The level and pressure of the liquid at the xenon condensing column is controlled and quantities of liquid oxygen is vented from the xenon condensing column at a constant level. The vented liquid oxygen is exchanged to high pressure oxygen gas in order to evaporate it, and this evaporated gaseous oxygen is supplied to a xenon absorptive column, and recovered as liquid oxygen through heat-exchangers.

    摘要: The present invention relates to a process for producing high purity xenon safely at a high yield from liquid oxygen in a main condenser of an air separating unit.The present invention involves a process for concentrating and recovering xenon by gasifying and introducing liquid oxygen led out from the main condenser in the air separating unit into an adsorption column field with an adsorbent which adsorbs xenon for adsorption and desorption, and a process for rectifying and recovering xenon by introducing concentrated xenon gas into a solid-gas separating column, which is cooled to a temperature at which xenon is solidified but components other than xenon such as oxygen and krypton in the concentrated xenon gas are not solidified to, catch xenon by condensation, then heating the solid-gas separating column after evacuating gas components remained therein.

    摘要: A method of consumable electrode arc welding is shown wherein the leading consumable electrode wire is mounted in parallel with a trailing filler wire, the latter inserted into a molten metal bath. Welding current is divided between the consumable electrode wire and the filler wire. These modifications improve the wettable boundary of the molten metal bath, prevent defects in the weld, and provide a high speed, highly efficient and high quality method of welding carbon steels, alloy steels, as well as aluminum and its alloys in a fully automatic as well as a semiautomatic operation. In an apparatus utilizing the above method, a single torch contains the consumable electrode and filler wire. One or more insulating contact tubes containing filler wire are mounted in a gas shield in parallel with a conductive contact tube containing consumable electrode wire. The unit is small in size and light-weight, and thus convenient for a welder to carry or hold during operation. Appropriate selection of one of the filler wires provided allows multidirectional operation without reorienting the torch. The unit produces a high-quality weld at rapid welding rates and is suitable for automatic and semiautomatic operation.

    摘要: This invention provides a manufacturing process which produces highly purified Xenon economically and safely with high recovery efficiency. In this invention liquid oxygen containing Xenon, which is vented from the main condenser in the upper rectification column of the air separating unit, is sequentially fed into multiple adsorptive columns filled with an adsorbent to selectively adsorb the Xenon. By a sequence of adsorbing-desorbing steps, Xenon is gradually condensed and, at the final state, highly purified Xenon is recovered. Hydrocarbons (CmHn) are removed from the product gas by a catalytic process. Xenon at a purity as high as 99.995% and at a yield as high as 95% is obtained by use of the present process.

    摘要: An optical circuit device makes lightwaves respectively having different wavelengths fall on a filter at different incident angles, respectively. The optical circuit device includes a filter, a mirror and a planar lightwave circuit provided with grooves holding the filter and the mirror therein, and an optical waveguide. The optical waveguide has a receiving part that guides a lightwave to the filter, a multipath reflection part in which the lightwave is reflected repeatedly, and an emitting part that guides lightwaves transmitted by the filter to an emitting end surface. The lightwave falls on the filter at least at two incident angles. The multipath reflection part is provided with a bend waveguide. The filter and the mirror are disposed substantially parallel to each other.

    摘要: An energy storage circuit includes a first capacitor connected with a power generating element via a first diode and a second capacitor connected with the power generating element via a second diode and a switch. The conduction state of the switch is controlled using the potential difference between its second and third electrodes (driving voltage V). The driving voltage when the switch enters its conductive state is higher than the driving voltage when the switch enters its non-conductive state.
