Title: Hydraulic drilling jar for large hole
Inventor: ROBAATO DABURIYUU EBANSU
IPC: E21B31/113
Filed: 1992-03-02
Abstract: PURPOSE: To separately control increase in the diameter of an excavated fluid hole extending through a jar and both upward and downward jarring actions. CONSTITUTION: A double-acting hydraulic drilling jar 1 includes a mandrel 2 arranged in the housing 3 so as to be longitudinally slidable. A hammer 69 is disposed in the mandrel 2 to impart upward and downward jarring forces to the drill strings in the interaction with the anvil surfaces 64, 66 in the housing. A hydraulic valve arrangement permits the storage of large amount of static force before releasing the hammer 69 to strike the anvil surfaces with a great force. The hydraulic valve arrangement includes a tripping valve positioned to be actuated by a first pair of engaging surfaces in response to downward movement of the mandrel 2 in the housing 3 and a second pair of engaging surfaces in response to upward movement of the mandrel 2 in the housing 3. Thus, independent control over the upward and downward jarring action is achieved.

Filed: 1986-04-05
Abstract: PURPOSE:To prevent the generation of foam in welding glass by providing a protective film consisting of one kind of metal selected from Cr, Ti, Cu, and Zn or the oxide of said metal between the welding glass and material to be joined. CONSTITUTION:The layer consisting of one kind of the metal selected from Cr, Ti, Cu, and Zn or the oxide of said metal is provided between the welding glass and the material to be joined. The protective film 11 consisting of, for example, metallic chromium or chromium oxide is formed by sputtering, vapor deposition, etc., to 500Angstrom -5mum, more preferably to 500-3,000Angstrom  film thickness. The protective film 11 acts as a barrier to insulate the layers from each other at the time of heating and glazing the welding glass 7 to a molten state. The reaction of the welding glass 7 and the magnetic film 5 is thereby prevented and the generation of the foam is prevented.

Abstract: PURPOSE:To prepare the titled single crystal having high resistance without adding any additive component with high reproducibility and economically in a high-pressure liquid sealing pulling method by pulling up GaAs melt having a small range of temp. variation reduced by impressing magnetic field at high speed. CONSTITUTION:Starting materials and a sealing material in a crucible 3 provided in a high pressure vessel 1 are melted to form a molten liquid layer 6 of B2O3 at the top of the crucible and a melt layer 5 of GaAs in the bottom of the crucible. A pulling rod 8 is then moved downward, and when a seed crystal 7 is brought into contact with the melt 5, magnetic field is impressed by a magnetic field impressing apparatus 11 to the melt 5 to regulate the range of temp. variation near the boundary surface of the melt to below 1 deg.C. GaAs single crystal 10 is grown by pulling up the seed crystal 7 with >=15mm./hr pulling speed while rotating the seed crystal at a specified speed maintaining the range of the temp. variation.

Title: Production of zn-al alloy-plated steel wire excellent in corrosion resistance and fatigue resistance
Inventor: OCHIAI YUKIO
IPC: C23C2/38
Filed: 1990-03-29
Abstract: PURPOSE:To obtain the steel wire by specifying the thickness of an alloy layer after secondary plating in a method for applying hot-dip galvanizing as primary plating to a steel wire and subjecting this steel wire to immersion into an Al-containing Zn alloy bath as secondary plating. CONSTITUTION:A steel wire is subjected to primary plating and then to immersion, as secondary plating, into a bath of a Zn alloy containing 2-12% Al, by which a Zn-Al alloy-plated steel wire is obtained. In this method, the thickness of the alloy layer on the steel wire after secondary plating is regulated to 0.5-7mu. Although corrosion resistance can be improved by exerting hot-dip galvanizing as primary plating, a new alloy layer formed at this time contains a hard intermetallic compound and is hard and has strong preferential orientation in its growing direction. As a result, in the case where the origin of fatigue failure is formed in the new alloy layer, this failure is easily propagated and forms a crack having a size corresponding to the thickness of the alloy layer. Accordingly, it is desirable to minimize the thickness of the new alloy layer so long as it does not hinder corrosion resistance, and, by specifying the thickness as mentioned above, fatigue strength equal to that of conventional galvanized steel wire can be obtained.

Title: Method for welding synthetic resin film
Inventor: HIGUCHI GOROU
IPC: B29C65/78
Filed: 1983-05-06
Abstract: PURPOSE:To prevent peeling by performing perfect welding with a synthetic resin being a film substrate, by heating a film superposed part to be welded under pressure by a hot knife while simultaneously vibrating said hot knife in a press direction and a right- angle direction. CONSTITUTION:A film 3 is pinched under pressure and heated by an edge 6 in a welding part (d) and the outer peripheral surface of a pressure receiving roller 13 and the press pinched part of the film 3 is melted. In this state, the traverse vibration of a vibrator 10 is transmitted to the welding surfaces of an upper and a lower films 15, 15' which is doubly superposed through the edge 6 by folding back a fold superposed so that anti-fog treated surfaces are directed inside to a conveying direction and the anti- fogging agent interposed between surfaces to be welded is excluded by the mutual traverse sliding between the surfaces to be welded of the films 15, 15'. In the next step, both films are welded by a synthetic resin layer being the substrate of the film 3. At the same time, the leading end of the film 3 projected to the left of the welding part (d) is pinched and drawn to a left direction by an upper and a lower conveyors 16, 16' and cut at the welded part of the film but, because the upper and the lower films 15, 15' at the leading end edges 17 of the cut part are already welded mutually by the previous operation of the welding part (d), the cut part is formed into an individual side-seal type bag article 2.
