Title: Method for vacuum-refining extra-low carbon stainless steel
Inventor: KATAYAMA KENICHI
IPC: C21C7/10
Filed: 1995-03-20
Abstract: PURPOSE: To prevent the formation of excess chromium oxide by over-blowing and to control the end point with high accuracy. CONSTITUTION: At the time of executing vacuum oxygen decarburizing treatment and component adjustment to molten stainless steel subjected roughly to decarburization treatment by a VOD method, the basicity (%CaO)/(%SiO2 ) of slag is adjusted to 1.5-3.5. Successively, the chromium oxide concn. in the slag is calculated from the residual oxygen content ΣO2 in a vacuum vessel defined by ΣO2 =ΣO2in -ΣO2out and the oxygen blowing is stopped at the time point when the chromium oxide concn. reaches <40% and the decarburizing speed lowers to the target value, and further, the molten stainless steel is stirred with inert gas under high vacuum atmosphere, the decarburizing reaction is promoted with the solid oxygen in the slag.  Wherein, ΣO2in is the integrated quantity of the oxygen quantity blown from the lance and the oxygen quantity in the air leakage and ΣO2out is the oxygen integrated quantity of (O2 +CO+CO2 ) in the exhaust gas. It is desirable to adjust the basicity (%CaO)/(%SiO2 ) of slag within the range of 1.2-3.0 by using CaO-Al2 O3 base flux just before the vacuum decarburization treatment.

Title: Fluorescent lamp
Inventor: EBARA HIROYUKI
IPC: H01J61/44
Filed: 1981-06-09
Abstract: PURPOSE: To prevent the deterioration of the light output even when the tube wall load is increased, by coating the inner face of the tube type transparent air- tight container with the phosphor material mainly composed of specific amount of europium activted yttrium oxide phosphor material.  
     CONSTITUTION: The transparent air-tight container 1 forming the discharge path is bent at three positions into the cubic W-shape and formed to provide the discharge path as long as possible in the small occupied volume where the inner face is coated with the phosphor film 2. Said film is contaning at least 40wt% of europium activated yttrium oxide phosphor material. Consequently in a fluorescent lamp having heavy tube wall load of the air-tight container, the emission of the light from the phosphor material is promoted by utilizing the short wavelength ultra-violet ray having the wavelength of 185nm effectively resulting in a highly effective fluorescent lamp where the light output will never lower.

Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to supply medals or the like to an upper tank of each side island on both sides in the case that raising lifts are arranged on both islands at the center, and side islands are installed on both sides by arranging driven pulleys on both ends of a conveyer, and providing a driving part roughly at the lower center of the conveyer so that the conveyer can be driven in both directions. SOLUTION: A supplying conveyer belt between islands 30 is constructed by passing a belt 35 between driven pulleys 31 and 32 supported by axes on right and left of a frame 34, and a driving part 33 is provided roughly at the lower center of the conveyer 30. Power from a motor having reduction gear 40 of the driving part 33 is transmitted to the driven pulley 38 to drive the belt 35. This construction enables driving of the supplying conveyer belt between islands 30 in both right and left direction by merely controlling rotating direction of the driving force such as the motor having reduction gear 40, etc., in the driving part 33, and preventing trouble such as slipping of medals if the conveyer 30 is constituted longer. Therefore, medals can be distributed stably to each side island in the case that raising lifts are provided on both islands, and the side islands are installed on both right and left ends of the both islands.

IPC: G02F1/1333
Filed: 1988-04-11
Abstract: PURPOSE:To prevent the defective orientation by an electrostatic discharge and the touch of upper and lower electrodes and to provide least visibility to the transparent electrodes when no voltage is impressed by forming insulating films consisting essentially of SiO2 and ZrO2 between the transparent electrodes and oriented films. CONSTITUTION:A soln. contg. an org. silicone compd. and org. zirconium compd. is coated on the transparent electrodes 3 on glass substrates 1. The coatings are calcined by near IR irradiation in an atmosphere having the oxygen concn. higher than the oxygen concn. in the atm. to form the insulating films 6 which consist essentially of the SiO2 and ZrO2 and have high insulation resistance and high strength. The oriented films 4 are formed thereon. The generation of the defective orientation by the discharge of static electricity at the time of rubbing is, therefore, obviated. The touch that fine conductive powder breaks through the oriented films 4 and short-circuits the upper and lower transparent electrodes is prevented. Since the insulating films 6 have approximately the same refractive index as the refractive index of ITO films, the transparent electrodes are least visible when the voltage is not impressed.
