摘要： A centrifugal injection machine comprises a rotor arm bearing at each of a pair of free ends a pivotably mounted container. A holder which retains a multiplicity of workpieces is insertable into a capsule or cavity within each container. The rotary arm contains a reservoir associated with each container or liquifying a charge of material. Upon rotation of the machine at a high velocity, the liquified material is transferred from the reservoir to the container in a vacuum and is pressurized therein as a result of centripetal acceleration. Upon the termination of a predetermined interval, a trip mechanism is activated to rotate the containers so that the molten liquid which has not been injected under pressure into recesses in the workpieces is ejected or discharged from the containers. The containers rotate within a vacuum chamber which is depressurized prior to the centrifuge operation.

摘要： The present invention provides free flowing and moisture resistant compositions from normally hygroscopic compositions by a process of mixing the hygroscopic material with a sealing material and heat treating. By controlling the sealing material added, the heat treatment time, and the heat treatment temperature, the sealing material forms a glassy coating on the hygroscopic material that is impervious to moisture while retaining free-flow properties. The present invention particularly provides free-flowing and moisture resistant sodium titanate and potassium titanate compositions having a moisture pick-up =

摘要： The present invention provides ceramic compositions for preparing multi-layer capacitors, having high dielectric constants between about 4900 and 5400, dissipation factors below about 2.0%, high insulation resistance capacitance products and stable temperature coefficient characteristics, by a process of mixing a major ceramic component with one or more precipitated dopant components. By controlling the conditions of the system, precipitated dopant particles are charged oppositely to major ceramic component particles and are thus associated with the major ceramic component particles.
