Abstract: PURPOSE:To obtain a high-performance linear oxide superconductor of high reliability by individually heating and evaporating respective metallic materials making up the aimed oxide superconductor and by injecting, together with an oxygen-contg. carrier gas, the resultant ultrafine particles produced onto a substrate. CONSTITUTION:Respective metallic material making up the aimed oxide superconductor, e.g., respective ultrafine particles of Ba, Cu and Y, in a mutually mixed state, reach, through a main carrying tube 46 together with a carrier gas, an intermediate chamber 4; where an oxygen gas is introduced via a relevant inlet tube 29, so the oxygen gas is added to the carrier gas from the chamber 4 to a film-forming chamber 5, thus the oxidation of the above mixed ultrafine particles proceeds in a carrying tube 49.

Title: Detector for high-frequency current
Inventor: SATOU TAMOTSU
IPC: G01R15/18
Filed: 1980-12-01
Abstract: PURPOSE:To enable to prevent the production of an error due to a floating magnetic field and of an error due to magnetic saturation of a rodform magnetic core, by a method wherein two high-frequency detecting coils, coiled around a rodform magnetic core, are mounted at both sides of a conductor to be measured. CONSTITUTION:A high-frequency magnetic field, consisting of a high-frequency current component contained in a current flowing in a conductor 1, is generated in a concentric circle centering around the conductor 1. The high-frequency magnetic field generates a high-frequency induction voltage at detecting coils 2a and 2b by a focusing magnetic action of rodform magnetic cores 5a and 5b attached to a fixture stand 4, and induction voltages from the two detecting coils 2a and 2b are produced in a total sum at an output terminal 13. Over a floating magnetic field except a high-frequency current component flowing in the conductor 1 and existing in the proximity of the conductor 1, the induction voltages are not produced at the output terminal 3 resulting from the erasing of each other. This permits the reliable detection of a high-frequency current.

Each time an NNSS position measurement result is obtained, contents of the deviation table 11 are updated; and the omega correction quantity calculating circuit 12 supplies always optimum omega correction quantites LOP1S and LOP2S to the line-of-position calculating circuit 3. Consequently, a high-precision position measurement result is obtained in the output of the line-of-position calculating circuit 3.

CONSTITUTION:When a flywheel gear 4b and a worm gear 3 are at meshing positions, an installation plate 2 is shifted until the backlash between the both gears is eliminated, and the plate 2 is fixed onto a frame 7 by a screw 2a. Then, the helical gears 4a and 4b are shifted towards the frame 7, and the helical gear 4a is meshed with the worm gear 3, and an intermediate gear 4c and a gear 6 are meshed, and the helical gears 4a and 4b and the intermediate gear 4c set integrally are installed so as not to slip-off from a gear shaft 5 by utilizing an E-ring 8. Since the amount of dislocation of the helical gear 4a is less by the backlash portion than that of the helical gear 4b, the helical gear 4a is properly meshed with the worm gear 3.

Title: Hot water supply apparatus
Inventor: KOBAYASHI TOSHIHIRO
IPC: F23C99/00
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To recover latent heat of combustion exhaust gas while removing NOx by providing a water atomizing/supplying means in a supply/exhaust air passage on the upstream side of a heat exchanger thereby lowering combustion temperature or combustion exhaust gas temperature. SOLUTION: As a suction fan 36 is operated, outdoor air is introduced to a burner 22 as combustion air. During combustion, an upper solenoid valve 51 is opened and mist water is ejected from an upper nozzle 42 toward a supply fan 36. Combustion temperature of the burner 22 is lowered by that water and generation of NOx and NOx is reduced. Furthermore, NOx is reduced during combustion by hydrogen contained in steam and removed from combustion exhaust gas. Similarly, a lower solenoid valve 53 is opened and mist water is ejected from a lower nozzle 43 toward combustion exhaust gas. That water is ejected toward a region where NOx is generated easily and combustion exhaust gas is cooled when the water robs heat therefrom to produce steam. Consequently, generation of NOx is suppressed and generated NOx is dissolved into the ejected water and removed from combustion exhaust gas.

Filed: 1982-09-29
Abstract: PURPOSE:To provide chalcogen compd. which consists of specific ratios of Se and Ga and has excellent changes in electrical and optical properties when irradiated with heat and light. CONSTITUTION:Titled chalcogen compd. consists, by mol%, of 60-97% Se and 3-40% Ga.

The compd. is further less deteriorated by the repetition of the bleaching and the darkening, and since the crystal in the stage of the darkening is extremely fine and dense, the compd. is outstanding as a material for optical memory. The compd. has the photocurrent in the stage of the darkening larger by about 106 times as compared to the photocurrent in the stage of bleaching and the interesting electrical and optical properties such as the shift in the main peak position in the dependency of the photocurrent on wavelength are observed.
