    摘要： New ceramic resistive igniter elements are provided that comprise a first conductive zone, a resistive hot zone, and a second conductive zone, all in electrical sequence. In preferred igniters, at least a substantial portion of the first conductive zone does not contact a ceramic insulator. Preferred igniters of the invention have a rounded cross-sectional shape for at least a portion of the igniter length.

    摘要： A method of forming a sputter target/backing plate assembly comprises the steps of: providing a target fabricated from a first material having a coefficient of thermal expansion; providing a backing plate fabricated from a second material having a coefficient of thermal expansion; providing a block fabricated from a third material having a coefficient of thermal expansion; positioning the block on one side of the backing plate; positioning the target on the other side of the backing plate; and subjecting the target, backing plate and block to elevated temperature and pressure to bond the target, backing plate and block together. The third material is selected so as to have a coefficient of thermal expansion which counteracts the effects of the coefficients of thermal expansion of the first and second materials. The third material may be selected so as to have a coefficient of thermal expansion which is approximately the same as the coefficient of thermal expansion of the first material.

    摘要： New ceramic heating elements are provided that have a recessed portion for receiving an electrical lead. Such ceramic heating elements can provide a reduced cross-sectional dimension across element regions that interface with electrical lead(s) as well as a more secure engagement of an electrical lead. Heating elements can be highly useful in a variety of application, including e.g. for fuel ignition for gas cooking appliances as well as vehicular glow plugs.

    摘要： A high purity titanium polycrystalline target with uniform grain size and near ideal (103) crystallographic orientation and a method of making. Uniform grain size from 10 .mu.m-500 .mu.m is achieved by using a fine grain five inch diameter titanium billet produced by hot working an electron beam cast billet. Greater than 80% (103) crystallographic orientation is achieved while maintaining uniform and optimal grain size in the target. The result is a higher collimated deposition rate with increased efficiency of bottom coverage of vias and a highly (002) oriented titanium film.
