Title: Production of vanadium
Inventor: MARUKAWA YUUJIYOU
IPC: C22B34/22
Filed: 1983-12-13
Abstract: PURPOSE:To recover vanadium in the form of a mixture composed of metallic vanadium and vanadium carbide at a high yield by maintaining the mixture composed of vanadium oxide and carbon at a high temp. under a vacuum condition. CONSTITUTION:Carbon, for example, graphite powder is mixed with V2O5 which is obtd. by thermal decomposition of, for example, ammonium (meta)vanadate and is generally powder. The material in this stage is preferably of about 30 mesh of finer than said size and the C/V2O5 ratio is preferably about 0.1-5.0. The mixture is made to compact powder and is molded to a briquette, etc. to permit easy putting of said mixture into and out of a hermetic vessel for performing a reduction stage. Such molding is transferred into the hermetic vessel and is held at a high temp. of about >=1,000 deg.C under the vacuum of about <=0.01atm. The V2O5 is then reduced to V and VC and generally the mixture composed thereof is obtd. as the resulted product. If such product is held, for example, at a high temp. of about >=1,000 deg.C for specified time under a vacuum according to need, the product is decarburized.

Title: Thick ceramic coating method
Inventor: SATA NOBUHIRO
IPC: C23C24/10
Filed: 1986-10-01
Abstract: PURPOSE:To carry out desired thick coating when the surface of a thin metal is coated with ceramics, by cooling the metal wall from the outside during the continuation of a reaction so as to prevent the burnthrough of the wall. CONSTITUTION:A powdery mixture of a highly reducing element with a metal oxide is filled into the hollow part of a metal tube under pressure and the upper part of the filled mixture is heated to initiate a thermit reaction. While the position of the tube is controlled, the reaction is allowed to proceed to form a thick ceramic layer between the surface of the resulting melt and the surface of the inner wall. The metal wall is cooled from the outside with a water cooling jig or the like during the continuation of the reaction. By this method, a desired ceramic coating layer can be uniformly formed on the surface of a low m.p. metal or a thin metal.

Title: Magnetic card
Inventor: OTSU MASAMITSU
IPC: B42D15/02
Filed: 1987-09-18
Abstract: PURPOSE: To protect a magnetic recording layer from the external magnetic field by mounting a magnetic shield layer made of a superconductive material on a surface of the magnetic recording layer. CONSTITUTION: A magnetic recording layer 2 is protected from the external magnetic field by a magnetic shield layer 1 and a magnetic shield layer 3. In the case where a signal is recorded and reproduced on the magnetic recording layer 2, a magnetic head and the magnetic recording layer 2 are magnetically shielded from each other by the magnetic shield layer 1, so that the recording and reproduction cannot be performed as it is. In the recording and reproducing, the magnetic shield layer 1 made of the superconductive material is heated to more than a critical temperature by a heater 5, and a part indicated by the slash is changed from the superconductive state to the non-superconductive state.  In the non-superconductive state, the Meissner effect cannot be found, and the magnetic shield action disappears only in the part of the slash, whereby the signal can be recorded and reproduced on the magnetic recording layer 2. The magnetic shield layer 3 is mounted adjacent to the magnetic recording layer 2 in this case, but the same effect can be obtained when it is mounted on a rear face of a base.

Title: Repairing method of structure and repairing member of structure
Inventor: NAITO TAKESHI
IPC: B29K63/00
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To easily repair a structure by hardening impregnated thermalhardening resin after attaching woven fabric made of reinforced fiber with the thermalhardening resin impregnated on it at a repairing point of a structure. SOLUTION: Woven fabric is woven by using carbon fiber for warp and alamide fiber for weft as reinforced fiber. Scuffing of the reinforced fiber is prevented by impregnating thermalhardening resin by epoxy resin and it is set in sufficient quantity required to secure permeability in a first resin impregnating process of this woven fabric. A second resin impregnating process is made by fixing such the woven fabric on a desired point to be repaired by using a proper adhesive and a proper hardening agent. Thereafter, both of epoxy resin in this second resin impregnating process and expoxy resin in the first resin impregnating process are hardened at normal temperature. Both of the epoxy resin becomes favourable in compatibility by using the same kind of resin for the thermal-hardening resin to be used for the first and second resin impregnating processes.

IPC: G01J1/02
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a rolling door shutter sensor which can clearly show the stuck position of a reflecting sheet by preparing a visible light-emitting part which projects the visible light in a same direction as the infrared rays which are projected from a light projection part. SOLUTION: A door shutter sensor 1 includes a visible light-emitting part 20 and a switch 21. The part 20 is set in a same direction as a light-receiving part 2 and a light projection part 4. The switch 21 is located between a power supply part 7 and the part 20. As a result of such a constitution, the visible light emitted from the part 20 is projected on the door shutter surface, when the switch 21 is closed with a door shutter kept closed completely after the sensor 1 has been attached at a desired position on the ceiling surface. Then a reflecting sheet can be stuck at the position where the visible light is projected. Thus, it is possible to clearly and visually decide a position, where the reflective sheet is stuck on the door shutter surface. Consequently, troublesome job requiring the reference to a correspondence table can be omitted.
