    摘要: Low density silicon nitride ceramics having improved bending an specific strengths over known silicon nitride ceramics derived from silicon nitride powder and polysilazane precursors are prepared by (A) intimately mixing about 50-80% by weight of silicon nitride powder with about 15-50% by weight of perceramic polysilazane binder, (B) pulverizing the mixture to form particles having a particle size smaller than 105 micrometers, (C) separating from those particles any particles having a particle size larger than about 105 micrometers, (D) molding the resultant composition having a particle size not larger than about 105 micrometers, and (E) pyrolyzing the molded composition in an inert atmosphere to a temperature of about 1200.degree.-1450.degree. C.; said preceramic binder being at least one polysilazane prepared by reacting an organodihalosilane with ammonia, treating the ammonolysis product with a basic catalyst which is capable of deprotonating an NH group that is adjacent to an SiH group, and quenching the resultant product with an electrophilic quenching reagent.

    摘要: This invention pertains to a lamp socket assembly for use in automotive applications and the like. The assembly includes a housing, a contact insert, and a body. The contact insert is captured in the cavity of the housing by the body. The body is welded to the housing. Lugs on the body secure the assembly to a panel. A seal is placed between a flange on the housing and the panel to seal the assembly to the panel. Contacts are retained in the contact insert by engagement of U-shaped portions in slots of the contact inserts. Blade terminals are inserted through windows in the housing, contact insert, and contacts to interlock the terminals with the contacts and to keep the contacts secured in their positions. A socket connector is sealingly secured to the housing and prevents moisture from entering the housing. In an alternative embodiment, no socket connector is provided but the blade terminals are crimped to wires for connecting the socket assembly to a source of electric power. In still another embodiment, the socket connector includes a protrusion for interlocking the body and the base together.
