Abstract: A method for the manufacturing of parts, especially molds or cores, by a deposition technique, comprising the steps of: depositing a layer of a pourable composite material containing particles with a binder material coating, into a process area of a defined length and width fitting to the dimensions of a part to be manufactured; applying a moderating agent onto said composite material layer in a selective sub-area of said process area; inducing energy to solidify said selective sub-area, respectively the area of said process area void of said moderating agent; repeating the aforementioned steps; and separating of solidified composite material from non-solidified composite material.
Abstract: There is disclosed a superconductor junction structure comprising: a first superconducting layer of an oxide superconductor formed in a desired pattern on a substrate; a non-superconducting layer of a non-superconductor formed on at least a part of the side faces of the first superconducting layer, a portion of the surface of the substrate near the part, and a top face of the first superconducting layer; and a second superconducting layer of the oxide superconductor formed on the non-superconducting layer, the non-superconducting layer being formed thin at the part, and forming a tunnel barrier.
Abstract: A process is described for the hydrided of halogen-substituted compounds of the second to fourth period of Groups III to V of the periodic system, with the exception of gallium, aluminum, carbon, or nitrogen. A finely-granulated aluminum is added to a molten salt melt that consists of 50-67 molar % AlCl.sub.3 (anhydrous) and 50 to 33 molar % of sodium chloride. Then to the stirred, or by some other means dispersed suspension, hydrogen is introduced to hydrided the finely-dispersed aluminum. Thereafter the mixture is reacted with the halogen-substituted compound and the resulting hydrided compound is renewed.

Abstract: In a method of soil nailing a soil nail is placed in the ground by being fired from a barrel of a launcher, the method including the steps of loading the nail into the barrel with the nail being a loose fit in the barrel, providing the nail with a sabot which is a sliding fit in the barrel, supporting the barrel such that a forward end of the barriel is spaced from the surface of the ground into which the nail is to be fired, admitting pressurized gas to the barrel to apply an accelerating force to the sabot so as to drive the sabot and with it the nail towards the forward end of the barrel, allowing the nail to travel towards the ground surface such that the sabot exits from the barrel thereby discontinuing the accelerating force and allowing the nail to thereafter continue travelling to penetrate and become embedded in the ground under its own momentum.

Abstract: An abnormality of a key component of an electrostatic image-recording machine is detected using a surface potentiometer originally installed in the machine for use in controlling the charging voltage of the photoreceptor drum. The detectable components are: main charger, transfer charger, discharge lamp, and developing roller. They are judged abnormal if the voltage of the drum surface is out of a normal range when they are functioned before an actual recording process (or during warming-up of the machine).
