Title: Isotopically pure single crystal epitaxial diamond films and their preparation
Inventor: BANHOLZER WILLIAM FRANK
IPC: C23C16/27
Filed: 1991-06-17
Abstract: The present invention is directed to the production of single-crystal diamond consisting of isotopically pure carbon-12 or carbon-13. The product is believed to be like that diamond product in application Serial No. 448,469, but is made by a different method. In the present invention, isotopically pure single-crystal diamond is grown on a single crystal substrate directly from isotopically pure carbon-12 or carbon-13. One method for forming isotopically pure single-crystal diamond comprises the steps of placing in a reaction chamber a single crystal substrate heated to an elevated CVD diamond-forming temperature. A gaseous mixture of hydrogen and a hydrocarbon of isotopically pure carbon-12 or carbon-13 is provided in the chamber. The gaseous mixture then is at least partially decomposed in the chamber to form an isotopically-pure single crystal diamond layer on the single crystal substrate disposed therein. The thus-formed isotopically-pure single crystal diamond layer optionally may be removed from the single crystal substrate. Another method for forming isotopically-pure single-crystal diamond comprises diffusing isotopically-pure carbon-12 or carbon-13 through a metallic catalyst/solvent under high pressure to a region containing a single crystal substrate to form an isotopically-pure single-crystal diamond layer on said single crystal substrate. The single crystal substrate is stable under the high pressure and elevated temperatures used during the diffusion process. The single crystal substrates optionally may be diamond, including the isotopically-pure single-crystal diamond films formed by the inventive method disclosed herein, thus forming multi-layered diamond structures.

Date Oct. 5, 1995A method and apparatus for processing rechargeable batteries include using a processor arranged to monitor the voltage of a battery when it is being discharged and to terminate the discharge after detecting that the rate of change of the voltage has passed through a termination pattern indicative of exhaustion of a cell of the battery. The determination is made by monitoring the voltage during discharge and detecting when the voltage curve thereof exhibits first convexity followed by concavity. The degree of convexity and concavity, and the time interval within which they must occur, are determined by the processor. The discharge is also terminated if the voltage reaches a predetermined voltage or if, after the termination pattern is detected, and before the voltage has reached a predetermined voltage, a predetermined amount of charge is removed from the battery. The invention also envisages recharging the battery first at high rate until the amount of charge returned to the battery is no more than the charge removed from the battery before the discharge was terminated. The charge may then be continued at a lower rate until the battery is overcharged to a predetermined extent.

Abstract: In a CDMA communication apparatus, two receiving circuits 2-1, 2-2 demodulate signals received by respective antennas 1-1, 1-2 and output reception signals. Two delay profile circuits 3-1, 3-2 associated with the receiving circuits shift the phases of the reception signals from the receiving circuits every predetermined interval, and correlate the reception signals with respect to known data to thereby output correlation value data. A searcher circuit 4 retrieves peaks from at least two correlation value data derived from the delay profile circuit and compares them. The power supply to at least one of the receiving circuits is then disconnected by switches 7-1, 7-2 and the oscillation frequency of a clock in the  communication apparatus is reduced based on this comparison.
