    Abstract: A matrix formation process 10 is configured with CVI process 12 and PIP process 14, 15, 16 in which a co-polymer containing at least polycarboxysilane (PCS) and polymethylsilane (PMS) is applied. Crosslinking of each polymer is performed at an intermediate temperature which is lower than the pyrolysis temperature of the polymeres. Polymer impregnation process 15 for infiltrating the co-polymer into a matrix, and inert gas firing process 16 for firing the material at a high temperature in an inert gas atmosphere. In the crosslink process, the mixed polymer is held at about 573K to 723K for a predetermined time. The conversion ratio of the co-polymer crosslinked into SiC in the subsequent firing process is increased, efficiency of filling SiC in the PIP process is increased, and an airtight ceramic-based composite material can be manufactured efficiently within a short time.

  • Patent number: 6337605
    Abstract: The present invention concerns an oscillator (20) intended to supply a periodic electric voltage (Vo) at a predetermined frequency (f). This oscillator includes: a reference source (23) able to provide a reference voltage (Vref), this reference source including a resistor (R) linked to said voltage; and supply means (24) able to receive the reference voltage and to supply said periodic voltage at said predetermined frequency, the supply means having a first temperature coefficient (&agr;24) so this frequency can vary under the influence of the temperature. This oscillator is characterised in that the resistor is formed to give the reference source a second temperature coefficient (&agr;23) equal to the first temperature coefficient, so that the temperature has the same influence on the reference voltage and on the supply means, which allows the periodic voltage to be supplied independently of the temperature.

  • Patent number: 6334962
    Abstract: A process of supplying moisture at low flow rates which permits high precision control of the flow of moisture to a semiconductor manufacturing line from an apparatus for the generation of moisture, characterized in that the flow of hydrogen to a moisture-generating reactor is controlled by means of a flow controller in such a way that an amount of hydrogen as fed is gradually increased from the start and reaches a specific set level such that when a specific time has passed, a predetermined rate of moisture begins to be produced and supplied to the semiconductor manufacturing line. The moisture is generated in the apparatus for generation of moisture in which hydrogen and oxygen are (a) fed into a reactor provided with a coat of platinum on the wall in the interior space, (b) enhanced in reactivity by the platinum catalytic action, and (c) caused to instantaneously react with each other at a temperature lower than the ignition point to produce moisture without undergoing combustion at a high temperature.

  • Patent number: 6336051
    Abstract: An agricultural harvesting machine (harvester) is automatically controlled and steered so as to completely harvest all crop in a field. A Global Positioning System (GPS) and an Inertial Navigation System provide data regarding the position and orientation of the harvester in a field. A Field Coverage Planner constructs a field coverage plan which defines a path for the harvester to follow in cutting crop from a field. Video images of the field in front of the harvester are derived alternately from two video cameras mounted on opposite sides of the harvester. The video images are processed in a Video Processing Computer to detect the crop line between cut and uncut crop and generate steering signals for steering the harvester along the crop line. Video images are also processed to detect the end of a row at the end of a field and supply a measure of the distance to the end of the row.
