Title: Formation of optical fiber
Inventor: BENKATA ADEISESHIYAIA BAGABATO
IPC: G02B6/10
Filed: 1984-09-26
Abstract: A process for manufacturing a preform from which is drawn an optical fiber, the core of which comprises layers of different glass composition. Layers of glass soot are deposited on the flat, longitudinally extending sides of a thin, elongated mandrel. Adjacent soot coatings have different refractive indices. A preliminary coating of cladding glass soot is deposited on the laminated soot structure. The resultant composite body is consolidated and stretched to form a rod or core structure upon which the final coating of cladding soot is deposited. The resultant composite body is consolidated and drawn into an optical fiber. In a modification of the this method, the mandrel is removed after the planar soot coatings and preliminary coating of cladding soot are deposited thereon. The resultant soot body is consolidated and processed as described previously.

Title: Cathode-ray tube inspection pallet
Inventor: TANAKA YOSHIAKI
IPC: H01J9/42
Filed: 1985-09-10
Abstract: PURPOSE:To enable the automation of inspection of a cathode-ray tube, by providing an inspecting section on the body of a cathode-ray tube inspection pallet, a contact section for sending and receiving a signal to and from the outside of the pallet, and a sliding section which can be slid on the body of the pallet to insert the neck of a cathode-ray tube into the inspecting section. CONSTITUTION:When a cathode-ray tube 1 is received from an external transfer unit as a sliding section 12 remains protruded from the body of a cathode-ray tube inspection pallet, the tube can be transferred in a vertical direction without coming into contact with an inspecting section, because the sliding section remains protruded forward from the pallet body. After the cathode-ray tube is positioned and grasped by a pincher 11 on the sliding section, the sliding section is moved back to insert the neck 10 of the tube into the inspecting section to complete the setting of the tube on the pallet. Because of the setting, the connector of the inspecting section is electrically coupled to the cathode-ray tube, and a deflection yoke 19 and a purity coil and convergence coil section 20 are placed in prescribed positions. In each inspection position on an automatic inspection line, the cathode-ray tube is electrically coupled to an external inspection circuit through a contact section 26 so that the tube is subjected to a prescribed inspection.

Title: Method of stacking upper layer thin film over oxide superconducting thin film
Inventor: TANAKA SATOSHI
IPC: C01G1/00
Filed: 1993-07-19
Abstract: PURPOSE:To form a thin film of good crystallinity through formation of a good interface by making the substrate temperature in forming a non- superconducting film and insulator film under the maximum temperature not adversely affecting mutual diffusion and over the minimum temperature by which the crystalline thin film grows. CONSTITUTION:In stacking an SrTiO3 thin film over a Y1Ba2Cu3O7-x oxide superconducting thin film, film-forming is made at a substrate temperature lower than a temperature by which mutual diffusion occurs in an interface. Also, an Au thin film which is to be further stacked over this SrTiO3 thin film is formed at a substrate temperature by which a mutual diffusion does not occur between the Y1Ba2Cu3O7-x oxide film and the SrTiO3 thin film. Consequently, very little mutual diffusion in the interface occurs, thus forming a sharp interface.

Abstract: PURPOSE:To rapidly expel ethylene from the periphery of a stored product, by regulating the feed rate of air, gaseous carbon dioxide and nitrogen gas to a storehouse and controlling atmospheric gas partial pressure of oxygen, carbon dioxide, etc., in an atmosphere under a slight reduced pressure. CONSTITUTION:For example, half of air in a storing chamber (43a) is replaced with N2 from a nitrogen supply source 17 and evacuated with a vacuum pump 47 to provide 400Torr internal pressure. When CO2 is then introduced from a carbon dioxide supply source 15 to regulate the internal pressure to 450Torr, the O2 concentration can be adjusted to about 9% and the CO2 concentration can be adjusted to about 11%. The interior of the storing chamber (43a) is then evacuated while regulating pressure and flow rates from respective pressure sources 13, 15 and 17 of air, CO2 and N2 with pressure regulators (23a), (27a) and (31a) and flow regulators (25a), (29a) and (33a) of a gas composition/pressure regulating means (21a) and continuously feeding the gases so as to provide 450Torr internal pressure. The atmosphere is kept at a regulated atmosphere of about 9% O2 concentration and about 11% CO2 concentration and cooled to a given temperature by a cooler (51a). Thereby ethylene can be more rapidly expelled from the periphery of a stored product.

Title: Continuous mixing method for powdery or granular substance
Inventor: SAKAKIBARA TOICHI
IPC: B01F25/90
Filed: 1987-08-11
Abstract: PURPOSE:To continuously mix a large amount of powdery or granular substances with a simple apparatus by allowing powdery or granular substances which have been piled on and conveyed by a belt conveyor to fall from the outlet end of the belt conveyor, whereby a mixer placed in a position lower than the outlet by a predetermined level difference rotates and rod-shaped vanes in the mixer strike against the powdery or granular substances. CONSTITUTION:The outlet end of a belt conveyor 1 is related to the inlet end of the next belt conveyor 1 placed at a lower level. Then, powdery or granular substances 4 which have been so piled on the belt conveyor 1 as to form layers and conveyed in the direction indicated by an arrow are allowed to fall from the outlet end. Upon the falling, a mixer 5 placed in a position lower than the first belt conveyor 1 by a predetermined level difference H is rotated by the energy of the falling substances 4, and a rod-shaped lattice vane 8 of the mixer 5 strikes against the powdery or granular substances 4 having large and small particle diameters, whereby the substances are mixed and discharged as a material 6. In this method, the various kinds of powdery or granular substances 4 are conveyed, as a pretreatment, in the form of a sandwich with a layer of a submaterial 3 being superposed between layers of a main material 2. Thus, powdery or granular substances such as construction materials can be continuously mixed with the simple apparatus.

Title: Lead for electronic part
Inventor: SHINODA TAKEHIKO
IPC: C23C2/08
Filed: 1991-08-09
Abstract: PURPOSE:To provide excellent weldability and solderability with aluminium, smoothly conduct the welding with aluminium without causing troubles such as facility stop, and enhance productivity. CONSTITUTION:On the outer circumferential surface of a metal wire 1, a tin- plated layer 2, a soldered layer 5 consisting of 80-95wt.% of tin and the remainder of lead, and a tin-lead alloy soldered layer 6 consisting of 97-100wt.% of tin and the remainder of lead are applied successively from under. Since the outermost plated layer 6 having a small lead content prevents the adhesion of the middle solder layer 5 improving the solderability to a welder pass line, the stop frequency of the facility (welder) resulted from the plating layer adhesion is highly reduced, and productivity is improved. Further, since the content of lead is optimized, the formation of blow holes at the time of butt welding with aluminium is also prevented.
