摘要:
An instrument for recovering the functions of the carpal joint, the hand and the fingers including a ballonet operatively connected to an air supply for subjecting the ballonet to repeated expansion and contraction by feeding and discharging compressed air thereto. Finger-engaging members being provided on the outer surface of the ballonet. Fastening members being provided on the outer surface of the ballonet for fixation of the carpal joint region and the region adjacent thereto. An individual's hand positioned within the finger-engaging members and the fastening members is extended and fanned as the ballonet is inflated and contracted as the ballonet is deflated.

A method for manufacturing a microparticulate anatase or rutile titanium oxide dispersion from a peroxotitanic acid solution optionally containing tin, wherein the method for manufacturing an anatase or rutile titanium oxide dispersion is characterized in that the peroxotitanic acid solution is fed continuously to a flow reactor and subjected to hydrothermal treatment at 150 to 250° C. and 0.5 to 10 MPa. The invention makes it possible to provide a method for manufacturing a microparticulate anatase or rutile titanium oxide dispersion having excellent stability in regard to the titanium oxide microparticles and enabling a high-transparency photocatalytic thin film to be produced, and to provide a member having a photocatalytic thin film formed on the surface using this dispersion.

A WDM based sensor system, a method of interrogating a plurality of sensor elements, and a WDM based sensor interrogation system. The WDM based sensor system comprises a WDM MUX/DEMUX element for demultiplexing an optical input signal into a plurality of substantially non-overlapping signals in respective sensing channels; one or more sensor elements disposed in each sensing channel; wherein the MUX/DEMUX element multiplexes sensing signals from the respective sensing channels into an optical return signal; and a detector element for detecting the sensing signals in the multiplexed optical return signal.

In implementing an induction heating stress improvement (IHSI) method in a nuclear plant, cooling characteristic with respect to the inner surface of piping is improved by appropriate structure/layout of nozzles, and further, the cooling effect when applying IHSI to a real machine is verified by installing a thermometer, as well as air in the portion subjected to IHSI is removed by heating the piping prior to the execution of IHSI.

According to the present invention, incineration ashes of sewerage sludge are compacted with pressure, but without additives, to have the bulk specific gravity of 0.9-2.5. Since the green compact has sufficient strength and reduced volume in comparison with the incineration ashes before compacting, it enables mass dumping without causing secondary pollution. Moreover, if the green compact is fired to have the bulk specific gravity of 1.4-3.5, both the volume and weight are reduced much more, realizing easy handling of the resulted burned product.

A method for heating a riser of a molten refractory material in which after a heat molten refractory material is poured into a mold, a melt of the molten refractory material at an upper portion of the mold is directly subjected to induction heating by conducting an electric current by application of an AC voltage at a frequency of from 50 to 1,000 KHz to an induction coil with at least 2 windings around the riser portion containing said melt without induction heating the upper portion of the mold.

In an electromagnetic fluid operating apparatus such as an air compressor in which a piston with an armature axially reciprocates along a path substantially at a right angle to the magnetic flux generated by a stator core due to alternate operation by electromagnetic attraction and mechanical repulsion, exact collimations are automatically established between the armature and the stator core and between the piston and a cylinder for the piston when they are assembled together, thereby minimizing biased frictional abrasion of coacting sliding surfaces. Provision of an internal air reservoir at the air outlet terminal effectively reduces pulsation of air supplied by the apparatus.

摘要:
A handling method for a natural circulation boiling water reactor having a chimney having cylindrical chimney shell disposed above a core in a reactor pressure vessel, a plurality of square tubes disposed in the chimney shell, and a grid support plate with grid holes supporting and in communication with a lower end portion of the square tubes so that adjacent square tubes are disposed at an interval which exceeds the width of one square tube between them. The method includes steps shifting predetermined ones of the square tubes to the interval between the square tubes, and performing maintenance and inspection of members around a core via the grid holes which appear at positions from which the predetermined square tubes are taken out due to the shift of the predetermined square tubes.

A functional optical device has cores which are trenches, different portions of the cores being formed from different core materials. The optical device can be formed by forming trenches 5,7,9 within a substrate (normally a substrate 1 covered by a cladding layer 3), covering at least part of at least one trench 7 with a cover 11, depositing a first cladding material to fill the trenches 5,9 which are not covered, removing the cover 11, depositing a second cladding layer 15 of a second cladding material to fill the trenches 7 which were previously covered, removing core material outside the trenches 5,7,9 and applying a cladding layer to cover the trenches.
