摘要： A surface-mount power resistor may be fabricated using a power resistor of conventional design as its core. A conventional resistor is reworked so as to flatten its leads from a point near their emergence from the generally tubular body of the resistor to the ends of the leads. The reworked resistor is then encapsulated from a point on the flattened portion of one lead to a corresponding point on the other lead, with the resulting mold being shaped as to have at least two opposing flat surfaces. The ribbon-shaped portions of the leads which exit from the molded body are then shaped as desired to afford the finished product. Similar surface-mount electrical components may be fabricated for any component with axial leads.

摘要： A lead immersion bath and method of superficially exchanging a tin layer for a lead layer, and a lead-tin alloy layer, respectively, which bath comprises an alkaline solution of a lead (II) compound and a complexing agent, in which the complexing agent has been chosen so that the complex constant of the lead complex in the solution used is smaller than the dissociation constant of hydroxyplumbite ions. The lead-tin alloy layer is obtained by a thermal treatment between 183°C and 232°C.

摘要： Permanent magnets are manufactured by grinding a magnetic phase having the composition RE₂(Fe, Co)₁₄B with a non-magnetic phase, orienting it magnetically, densifying and then sintering it. The non-magnetic phase may be a hydride or an alloy of a rare earth metal. The second phase must have a melting point lower than the magnetic phase.

摘要： A thin film capacitor is formed of a thin crystalline electrically insulative or semiconductive substrate. With the insulative substrate a thin conductive metal layer is deposited on the substrate and a thin film of a crystalline strontium barium niobate deposited on the thin conductive metal layer so that its 2.77 A spaced atomic planes are oriented in a non-perpendicular manner to the substrate and an additional thin conductive layer is deposited on the surface of the strontium barium niobate film. When a semiconductive substrate is employed the strontium barium niobate film is deposited directly on the substrate. These capacitors exhibit a low temperature coefficient of capacitance and a high capacitance density.

摘要： The invention provides a process for the production of coatings of condensation polymers on inorganic particles, in which the product consists mainly of polymer particles which particles contain one or a few pigment particles, and essentially no large aggregates and pigment-free particles. In the method the thickness of the coating can be adjusted through the quantity of monomer added.
In the process two separate stable suspensions are formed, one of these suspensions being that of a solid monomer in a first organic liquid, the other suspension being of finely divided inorganic particles in a second organic liquid, miscible with the first organic liquid. Further, said first suspension is added to said second suspension while stirring and heating said second suspension to the polymerization temperature of said monomer.
