Patent CA-2015976-A1 (CA)
Title: Plasma etching apparatus with surface magnetic fields
Inventor: HERSHKOWITZ NOAH
IPC: C23F4/00
Filed: 1990-05-03
Abstract: ABSTRACT      A glow discharge etching apparatus includes a magnetic assembly for creating a surface magnetic field in close proximity to the walls of an etching chamber.  An electrode is located within the chamber for supporting the object to the etched.  A radio frequency signal is applied to the electrode so that it will emit secondary electrons upon bombardment by ions from an etching plasma created within the apparatus.  A control plate may be positioned at various locations within the apparatus to regulate the amount of electron leakage to the control plate and thereby regulate the etching process.  This apparatus provides improved uniformity and directionality of etching due to a low gas pressure and the surface magnetic field.

Patent CA-2021487-A1 (CA)
Inventor: MUNOZ JESUS J L
IPC: B01J29/20
Filed: 1990-07-18
Abstract: The invention refers to a process for the obtainment of a catalyst useful in the isomerization of light paraffins, fundamentally based on acid treatment of a synthetic mordenite at temperatures between 40 and 100° C followed by treatment with steam-air at temperatures between 300 and 600° C which makes it possible to optimize the SiO2/Al2O3 framework ratio and the amount of extraframework aluminum of the zeolite.  The mordenite thus obtained is mixed with an inorganic refractory oxide such as Al2O3 and a metal of group VIII, basically Pt, is added in an amount between 0.1 and 0.5% by weight referred to the final catalyst.  The catalyst has been tested in the isomerization of light refinery fractions (C5 and C6) and has a high activity and selectivity of branched isomers with a low production of gases and a high octane number for the light gasoline obtained.

Filed: 1991-01-18
Abstract: A multi-output DC-DC converter comprises a field-effect transistor connected to a one terminal of a DC voltage source, the transistor having a parasitic diode coupled in parallel relationship therewith. A resonant circuit is coupled at one end to the other terminal of the voltage source and a first diode is connected between the transistor and the other end of the resonant circuit to allow a forward current to flow therein. A second diode is connected in parallel with a series circuit formed by the transistor and the first diode to allow current to flow in a reverse direction, the second diode having a recovery time much smaller than the recovery time of the parasitic diode. A first rectifier-filter is coupled to the resonantcircuit for developing a first DC output voltage, and a second rectifier-filter is coupled across the terminals of the DC voltage source through the transistor for developing a second DC output voltage. A third diode is connected between the DC voltage source and the second rectifier-filter for blocking a current flow which would otherwise flow through the first and second diodes and the second rectifier-filter. Deviations of the first and second DC output voltages respectively from a reference voltage are detected and the gate of the transistor is driven by switching pulses having a frequency variable as a function of the deviation of the first DC output voltage and having a duration variable as a function of the deviation of the second DC output voltage.
