Abstract: The invention relates to a method and the apparatus required for carrying out the method for the continuous production of billets or ingots of metals, in particular steels and Ni- and Co-base alloys using the method of electroslag remelting and electroslag continuous casting in downwardly open water-cooled ingot molds, in which the billet issuing downwardly from the ingot mold is pressed against at least one guide element arranged rigidly in respect of its position with respect to the ingot mold axis, by at least one clamping element arranged opposite the guide element, in such a way that the regions of the billet surface which are in contact with the guide or clamping elements change within short intervals of time, wherein at least one of the elements is driven to withdraw the billet while the others move with the billet and a contact with a current source can be made by way of at least one of the elements.

Abstract: A synthetic slag is produced by melting the mineral content of an organic carbon-containing mineral, for example, oil shale or tar sands, with a source of lime such as cement kiln dust. The organic carbon, especially hydrocarbon, content of the mineral is oxidized by oxygen gas, which typically is derived from air or an air/oxygen combination, in an exothermic reaction and the heat generated provides the thermal energy for the reaction between the mineral content and the source of lime. In this way the gaseous products will typically comprise nitrogen, unreacted oxygen, water vapor and carbon dioxide, and heat energy can be readily recovered from the hot off gas products evolving during the combustion reaction. The synthetic slag may be pelletized and employed as lightweight mineral aggregate or milled, or atomized and then milled, to cement fineness to provide slag cement.

Abstract: A method of controlling a magnetization easy axis of a ferromagnetic film, an ultrahigh-density, low power, nonvolatile magnetic memory using the control method, and a method of writing information on the magnetic memory. The method includes the step of arranging an electrode layer, a piezoelectric layer and a magnetic layer in a layered structure. Voltage is applied to the electrode layer to generate an electric field. Thereafter, lattice change is caused in the piezoelectric layer using the generated electric field. A magnetization easy axis of the magnetic layer is reversibly switched between in-plane and out-of-plane by exerting stress generated by the lattice change onto the magnetic layer.

Abstract: A number drawing apparatus includes a rotating unit and collecting holes. Each ball, supplied from a supply unit provided in the central portion of the rotating unit when it rotates, randomly rolls on a surface of the rotating unit. A centrifugal force by the rotation causes each ball to move outwardly from the rotating unit, and each ball is caught in one of catching holes. Unique identifying symbols are assigned to the catching holes. This enables the draw.

Abstract: A spring clutch has an arbor, a spring, and a sleeve. The spring at least partially surrounds the arbor and has a first portion coupled to the arbor to confine relative rotation of the first portion and arbor about an axis. The sleeve at least partially surrounds the spring and cooperates with the spring. The cooperation is sufficient so that an initial relative rotation between the arbor and sleeve in a first direction about the axis tends to uncoil the spring and bias the spring into firmer engagement with the sleeve. The cooperation is sufficient such that relative rotation in an opposite direction tends not to uncoil the spring and maintains the clutch in a disengaged condition.

Abstract: Disclosed is a method of electroplating a Ni—Fe—P alloy using a sulfamate solution and, in particular, a method of electroplating a Ni—Fe—P alloy using a plating solution containing nickel sulfamate, iron sulfamate, phosphorous acid, and a buffer agent. The method is advantageous in that a residual stress of a deposited layer is very low and has stable mechanical properties, and excellent thermal and corrosion resistance because the deposited layer is obtained by electroplating the Ni—Fe—P alloy using the sulfamate solution useful in a high rate plating process. Furthermore, the method can be applied to various parent metals such as stainless steel, Inconel and iron alloys, and to various fields because the chemical compositions of the deposited layer are readily controlled by varying the concentration of the plating solution.
