A quadrupole mass filter, or a multiple-pole mass filter in general, composed of a cylindrical main body made of an insulating material and having a star-shaped cross-sectional profile whose inward bulges are curved substantially hyperbolic, and four electrode layers of a high melting point metal deposited by a chemical vapor deposition (CVD) process. The four electrode layers are separated at the outward bulges of the star-shaped cross-sectional profile. The quadrupole mass filter has pre-rod electrodes.

This invention relates to an anode for use in an X-ray tube and a method of manufacturing the anode, and to a stationary anode X-ray tube. An anode base formed of copper or the like includes a recess formed in an end surface thereof and having an upwardly diverging inner peripheral wall. An anode target material such as tungsten is directly deposited in the recess by chemical vapor deposition.

Method of forming a catalytic bonding layer by chemical vapor deposition (CVD) onto carrier structures including internal combustion engine exhaust system and catalytic converter components, in order to bond a catalyst layer thereto, thereby providing a structure wherein additionally the bonding layer can be energized to promote catalytic conversion-activating preheating of the catalyst. In an electromagnetic induction catalytic preheating system, a ceramic lattice or a metallic network can form the base structure of the catalytic converter, wherein at least the latter is encompassed by an electrical/thermal insulating layer; around either induction coiling is wrapped and secured by a thermally insulating material. Upon engine start, current is electromagnetically induced in the catalytic bonding layer or the metallic network through the induction coiling. Furthermore, the specific heat capacity of the bonding layer is low, and its specific resistance can be predetermined; thus in heating quickly and efficiently, in tandem the catalyst is heated. The catalytic preheating is also made efficient by the insulating properties of the insulating layers.
