| 6445796 | Automatic telephone-line disconnect system A telephone disconnect system having a current-sensitive relay which automatically operates to electrically connect the telephone lines to the telephone network when the cradle switch of the telephone is closed, and which automatically operates to electri... | 09/03/2002 |
| 6328796 | Single-crystal material on non-single-crystalline substrate A method for making a multilayered structure with a single crystal film bonded to a polycrystalline substrate has the steps of: bonding a single crystal film to a polycrystalline substrate; and growing an epitaxial layer on said single crystal film bonded to said ... | 12/11/2001 |
| 6323108 | Fabrication ultra-thin bonded semiconductor layers The invention uses implantation, typically hydrogen implantation or implantation of hydrogen in combination with other elements, to a selected depth into a wafer with that contains one or more etch stops layers, treatment to split the wafer at this select... | 11/27/2001 |
| 6294109 | Ferroelectric and electroclinic liquid crystal materials with sub-ambient temperature stability, broad operation range, and fast dynamic response A new class of mesogenic compounds has the formula: ##STR1## where R1 is an ester (--COO--) group; R2 is H, NO2, CN, F, or Cl; R3 is H, CH2.dbd.CH, or (CH3)3 Si; k is 1 or 2; q i... | 09/25/2001 |
| 6285811 | Near-field optical microscope with infrared fiber probe A near field optical microscope according to the present invention has (1) a single mode infrared optical fiber made from chalcogenide glass, chalcohalide glass, or a combination thereof, having a probe end adapted as a probe for near field optical micros... | 09/04/2001 |
| 6265336 | High temperature ceramics derived from linear carborane-(siloxane or silane)-acetylene copolymers This invention relates to a new class of novel inorganic-organic hybrid ceramics that are formed from novel linear polymers of varying molecular weight and varying carborane content.... | 07/24/2001 |
| 6253615 | Method and apparatus for in situ measurements of corrosion of submerged surfaces An aspect of the present invention is an apparatus for inspecting a base of a liquid filled tank for corrosion, having (a) a housing for use in the liquid filled tank; (b) a set of one or more ultrasonic transducers mounted to the housing, for directing o... | 07/03/2001 |
| 6252262 | Metal passivating layer for III-V semiconductors, and improved gate contact for III-V-based metal-insulator-semiconductor (MIS) devices A passivating layer is provided for a III-V semiconductor. The passivating layer is preferably made of Fe and is used with III-V (especially GaAs) devices. At least one full monolayer of the passivating layer is formed, so that one full monolayer of the p... | 06/26/2001 |
