Patent CA-2133073-A1 (CA)
Inventor: RAMOS FERNANDEZ ANTONIO
IPC: H03K17/74
Filed: 1993-12-29
Abstract: The object of the disclosed system is the fast switching of high voltage and short duration pulses on loads which require high instantaneous intensities, in order to provide said pulses in both directions; the system is capable in switching narrow band signals, and therefore long duration signals. The system is based on a very low series impedance switching channel which is comprised of two high voltage capacitors (C1) in series with two rectifying groups (GR1 and GR2) connected in opposition and whose conduction status is activated by forced injection, through said groups, of a direct current controlled by a reactive network in series with a conventional low voltage unidirectional switch (CBT), thereby providing for its logical control (SL) from digital circuits TTL or CMOS. This system applies more particularly and immediately to wide band units which operate with high frequency radiations, particularly of ultrasonic type, and in fields such as diagnosis and non invasive medical treatment and non destructive tests of aeronautical and nuclear structures. <IMAGE>

Title: Demodulator for manchester-coded fm signals
Inventor: DENT PAUL W
IPC: H04L25/49
Filed: 1994-04-29
Abstract: Binary signals that are transmitted by Manchester coding and frequency modulation are demodulated based on the behavior of the phase or complex vector value of the received signal.  The polarities of the information bits mat be determined by measuring the phase excursions in the middles of the Manchester symbols.  A phase reference is established from a plurality of candidate phase references as a basis for comparison of the mid-symbol phase.  The phase can be measured at the start-points and end-points of the symbols and averaged, or measured a plurality of times during each symbol period to generate a reference phase.

Patent CA-2147632-A1 (CA)
Title: Imaging medium and process
Inventor: GRASSHOFF JURGEN M
IPC: G03C1/675
Filed: 1993-10-22
Abstract: Acid can be generated by exposing a mixture of a superacid precursor and a dye to actinic radiation of a first wavelength which does not, in the absence of the dye, cause decomposition of the superacid precursor to form the corresponding superacid, thereby causing absorption of the actinic radiation and decomposition of part of the superacid precursor, with formation of a pro-tonated product derived from the dye, then irradiating the mixture with actinic radiation of a second wavelength, thereby causing decomposition of part of the remaining superacid precursor, with formation of unbuffered superacid. Preferably, following these irradiations, the imaging medium is heated while the superacid is admixed with a secondary acid generator capable of being ther-mally decomposed to form a second acid, the thermal decomposition of the secondary acid generator being catalyzed by the pres-ence of the superacid. The acid generation process may be used for imaging by bringing the superacid or second acid into contact with an acid-sensitive material which changes color on contact with acid, or the superacid may be used to trigger polymerisation, depolymerisation or other reactions.

Title: Pcvd process and device for coating domed substrates
Inventor: HEMING MARTIN
IPC: C23C16/52
Filed: 1995-03-29
Abstract: A PCVD process is disclosed for producing coating layers of uniform thickness on domed substrates. The substrate surface to be coated is arranged in relation to the gas passage surface of a gas shower. In order to determine the appropriate processing parameters, in a first series of test for one type of substrate to be coated the size of the gas passage surfaces and gas mass flows through the gas passage surfaces are kept constant while the intervals between plasma impulses are gradually modified, starting from an initial value t A until an optimum value t eff is determined and until the uniformity of the thickness profile of the layers generated on the substrate may no longer be improved. If required, during a second series of tests the value t eff may be kept constant while the thickness profile of layers is further modified by further optimising local parameters and/or the gas mass flows until its uniformity may no longer be improved. The device has a gas shower subdivided into zones and whose gas passage surfaces are arranged in relation to a substrate to be coated. The zones are connected by supply lines to a source of non film-forming gas and to a gas source that supplies fresh gas.
