Abstract: METHOD FOR PREPARING IMPROVED POROUS METAL-HYDRIDE COMPACTS AND APPARATUS THEREFOR               ABSTRACT OF THE DISCLOSURE The present  invention  relates  to  a method  and apparatus   for   preparing   metal-embedded   porous metallic-hydride (pmh) compacts capable of withstanding repeated  hydriding -  dehydriding  cycles  without disintegrating.  According to the invention, the finely divided hydridable metal alloy hydride is admixed with a finely divided metal selected from Al, Ni, Cu or other transition metals and charged with hydrogen.  The resulting mixture is sintered in a furnace in which hydrogen  is  introduced  at  a  pressure  above  the equilibrium pressure  to  the  prevailing  temperature, mechanical  stress being applied simultaneously.   The compacts  obtained  possess  outstanding  stability r as shown by the fact that they have remained intact even after more than 6000 cycles.

Abstract: FABRICATION OF STACKED MOS DEVICES          Abstract of the Disclosure In a process for manufacturing vertically integrated MOS devices and circuits, gate oxide and a gate are formed on a semiconductor substrate such as a silicon substrate.  A layer of polysilicon is then deposited over the wafer, the polysilicon contacting the substrate silicon through a window in the gate oxide.          The substrate silicon and the polysilicon are then laser melted and cooled under conditions that encourage crystal seeding from the substrate into the polysilicon over the gate.  Subsequently, ions are implanted into the silicon substrate and the polysilicon to form source and drain regions.  By introducing the source and drain dopants after melt associated seeding of the polysilicon, the risk of dopant diffusion into the device channel regions is avoided.

Abstract: ABSTRACT         In the plasma arc torch of this invention the same gas may be used for generating a plasma and for secondary  gas  flow  for  cooling  the  torch  and  the workpiece.  A torch housing defines a chamber which has an outlet at the end of the housing. The torch also includes an electrode in the chamber near the outlet and means in the chamber  for  separating  the gas flowing towards the outlet of the housing into a primary gas flow adjacent to the electrode for generating a plasma and a secondary gas flow away from the electrode for cooling the torch and the workpiece.  In the preferred embodiment, air may be used for both the plasma forming gas and the secondary gas and the electrode has a halfnium insert.          The torch has a torch tip adjacent to the electrode and the torch may be started without a pilot arc by touching the workpiece with the torch tip.  No standoff between the electrode and the workpiece needs to be maintained and the torch operator simply drags the torch tip on the workpiece resulting in a more accurate cut or weld.

Abstract: ABSTRACT     A mass spectrometer having a thermospray ion source, suitable for the analysis of liquid samples is disclosed. The source comprises a strongly heated atomizing nozzle through which the sample is pumped into a spray chamber, and an aperture in a cone, through which the ions pass through an electrostatic lens into a region in which a mass analyser is situated.  An electrode generates a repulsive electrostatic field which improves the efficiency of the transmission of ions through the hole in the cone.  The electrode is situated downstream of the hole in the cone.  By further increas-ing the potential on the electrode the nature of the ions passing through the hole in the cone can be changed from largely adduct and cluster ions formed by association of solvent molecules with sample ions in the thermospray to largely pseudomolecular sample ions similar to those formed by conventional chemical ionization.
