Patent CA-2146908-A1 (CA)
Inventor: VERKUIL ROGER L
IPC: H01L21/66
Filed: 1995-04-12
Abstract: The appts. comprises a device for establishing an amount of junction capacitance of the junction between the desired layer and the underlying substrate, and providing a signal indicative of the junction capacitance. A device generates a point location alternating current (AC) photovoltage between the desired layer and the underlying substrate. The photovoltage has a sinusoidal magnitude and frequency and is propagated radially outward from a point location along the desired layer by a resistive nature of the desired layer at an attenuation and phase shift. The generating device further provides a signal indicative of the AC sinusoidal frequency. A device monitors the attenuation and phase shift of the propagated AC photovoltage as a function of radial distance remote from the point location. The attenuation and phase shift monitoring device provides first and second output signals indicative of a first and a second monitored magnitude and phase at first and second radial distances, respectively. A device is responsive to the junction capacitance signal, the AC sinusoidal frequency signal, and the first and second attenuation and phase shift signals for generating an output signal indicative of a sheet resistance RS of the desired layer according to a prescribed sheet resistance model.

Abstract: A description is given of a block, for example a vertically perforated brick, having inner cavities (2) which carry out a heat-insulating function,  and of a method of producing said block. In order to reduce the radiant component of heat transfer in these dark cavities (2), the inner surface of the cavities (2) are provided with a heat-reflecting coating. Said layer may contain aluminum or similar heat-reflecting components. The layer is  applied  by  vapor  deposition  or  spraying,   if appropriate also on the abutment side (1) of the block, and can be applied before the brick is fired or, specifi-cally,  fired in. It is also possible to add a water-soluble heat-reflecting component to the clay,  which component,  during  the  drying  and/or  firing process, migrates onto the surface.

Patent CA-2163281-A1 (CA)
Title: Satellite stabilization system
Inventor: LEHNER JOHN A
IPC: G05D1/08
Filed: 1995-11-20
Abstract: A  satellite  stabilization  system  compensates  for  the destabilizing torque introduced by solar radiation pressure by the emplacement of tabs of material angled relative to the back surfaces of the antenna reflectors to intercept solar rays.  The material of the tabs interacts with the solar radiation in substantially the same manner as the interaction of the material on the back surface of each antenna reflector to produce a radiation pressure and consequential increment in a torque about an axis of the satellite.  Each of the tabs is constructed in the manner of a plate or disk, and is attached by means of a spring mount to the back surface of one of the reflectors.  The reflectors are angled relative to each other, as well as to a body of the satellite which holds feeds for illuminating the reflectors, for directing beams of radiation from the feeds towards the earth.   Due to the angulation of the reflectors to each other, the total solar energy incident upon a pair of of the reflectors is generally unequal, this resulting in a net torque from the solar radiation pressure which tends to rotate the satellite.   By virtue of the angulation of the tabs relative to the reflectors,  an increased amount of solar radiation is received by the reflector which is angled away from the sun's rays, thereby to equalize the torque from both of the reflectors.

Title: D.c. motor actuator for light modification
Inventor: HANCHETT NEVILLE B
IPC: G02B7/182
Filed: 1996-03-21
Abstract: A light system includes a laser light generator and an array of motor-driven mirrors aligned to deflect a beam of laser light in various directions to create a light show.   The motors are operated in a controlled sequence by a motor controller.   The motors are small d.c. permanent magnet motors which are driven from a d.c.  source whose voltage  is  adjustable  to vary the frequency of oscillation of the motors and, hence the mirrors.          Connected to each motor is a small coil spring whose coil is carried on the motor shaft and which has two extended arms, one of which is secured to a nearby stationary member and one which is secured to the mirror shaft.   The mirror shaft is movable between two stops.   The spring acts to oppose the direction of motion of the motor such that the motor is normally stalled out and driven back to one of the stops before it can be moved  far enough to impact the other stop.

Patent CA-2184347-A1 (CA)
Title: Automatic side view mirror tracking system
Inventor: BROWN JAMES L
IPC: G01S15/931
Filed: 1995-02-28
Abstract: An automatic side view mirror tracking and control system enables drivers of articulated vehicles such as tractor trailers to keep visual contact with the side and rear of the trailer throughout a turn while backing the vehicle. This is accomplished without driver intervention through the use of a microprocessor receiving the outputs of either a plurality of ultrasonic transducers or a pair of fluxgate compasses. The microprocessor uses the aforementioned outputs to determine the rotational angle between the trailer and the tractor. Based upon these determinations, the mirror is moved to a position commensurate with the subject angle so that the driver of the vehicle is able to view the side and rear corner of the vehicle. A software filter prevents the mirror from being moved unless a predetermined change in the vehicle angle is detected.
Patent CA-2184511-A1 (CA)
Inventor: HOMAN EDWIN DARYL
IPC: B01D21/00
Filed: 1996-08-28
Abstract: A system for separation of fluids and drill cuttings received from a borehole during an under-balanced drilling procedure.  The system is designed to cope with significantly varied pressures and flow rates, particularly in relation to gas content of drill fluids returned to the surface during the drilling process in a production zone, and to provide effective separation and to reduce the detrimental effect due to the presence of the drill cuttings in the returned drill fluids.  In the present invention there is utilized a first stage, high pressure vessel in which a major portion of the gases ad drill cuttings are separated, and a second stage, horizontal low pressure vessel, preferably of greater volume than the high pressure vessel, in which further separating is achieved, including the separate removal of the drilling liquid to be returned to the drill tube.  Because in under-balance drilling, the most serious variation in the pressure of the returning fluid is due to rapid increases in the proportion of gases in the drill fluid, the system of the present invention includes features allowing the control of the operating pressure in the high pressure vessel by way of the flow control of the gases exiting the high pressure vessel while the remaining separating procedure continues to provide effective results.
