Inventor: FIELER ELEANOR ROTH
IPC: C09K8/528
Filed: 1994-05-02
Abstract: A method for placement of a long life scale inhibitor into a formation where variable density scale inhibitors are utilized. A  substantially low density non-reactive fluid is loaded into the intervals (20, 22, 24, 26) of the formation to be treated. Afterwards, a high density first stage scale inhibitor (16) is injected into the interval (20). Thereafter, a low density spacer fluid (18) is injected into the well (10). Next, a second stage high density scale inhibitor having a density lower than the first stage inhibitor is injected into me interval (22). Subsequently, a low density spacer (18) is injected into the well (10). Volume increments ace repeatedly injected with decreasing fluid densities until a desired zone has been treated. The entire treatment is then overflushed with an inert high density fluid. Use of this method allows even inhibitor distribution in intervals of a formation with permeability variations thereby preventing scale build-up.

Patent CA-2169160-A1 (CA)
Title: Pulse width modulated dc-to-dc boost converter
Inventor: THOREN CHRISTER
IPC: H03K17/0814
Filed: 1995-06-07
Abstract: A pulse width modulated DC-to-DC boost converter circuit (300) in which switching losses are minimized.  The circuit operates at a constant frequency and in continuous mode  (at  a  constant  current).    Turn-on  losses  are minimized by causing the parasitic intrinsic capacitance of the main switching device (302) to be discharged before the switching device is switched to the conducting state, and reducing reverse recovery current from the output rectifier (320) of the circuit when the output rectifier turns off.  Turn-off losses in the switching device are minimized by causing a condition of zero volts across the switching device at turn-off.

Title: High frequency power measurement
Inventor: MATSUNAGA DEREK
IPC: G01R21/133
Filed: 1994-11-03
Abstract: A monitoring circuit (10) for an electrosurgical generator (11) has active and return output conductors. Voltage, current (24) and the inverse of current (24) picked up inductively are provided to adder circuits for summing the picked up voltage (20) and current (24) and computing the difference of the picked up voltage (20) and the current (24). Root mean square to direct current converters (26 and 28) signal RMS average values of the sum and difference. A microprocessor squares the values and applies them to a formula wherein the sum signals (22) have rubtracted therefrom the difference signals (25); the results are divided by four to provide the root mean square of the power applied to the load (12). During desiccation the output is regulated in response to impedance to shut off output. A diagnostic circuit relates impedance load and output response during operation to a look up table or a microprocessor algorithm to calibrate. Feedback modifies the output when the adders determine the power applied to the load (12) in real time. A method has generator output to active and return conductors (14 and 15) and to inductive pick ups (16 and 17) for voltage and current (24), computes sum and differential values (25), changes root mean square to direct currents (24), squares the values and subtracts the differential from the summation, then divides the result finding the root mean square value of the power.

Title: Temperature compensation of ferroelectric liquid crystal displays
Inventor: HUGHES JONATHAN RENNIE
IPC: G09G3/36
Filed: 1995-02-28
Abstract: The invention provides an addressing scheme with temperature compensation for temperature induced changes in liquid crystal material switching parameters. Temperature compensation is provided by measuring liquid crystal temperature, and varying the length of strobe waveforms accordingly. A ferroelectric liquid crystal cell is addressed by row and column electrodes forming an x,y matrix of display elements. A strobe waveform is applied to each row in sequence whilst appropriate data waveforms are applied to all the column electrodes. At each display element the material receives an addressing waveform to switch it to one of its two switched states depending upon the polarity of the addressing waveform. The data waveforms are e.g. alternating positive and negative pulses of period 2ts. The strobe waveform has a zero for one time period is followed by a unipolar voltage pulse of significant duration e.g. equal to or greater than 0.25 is or more. This may result in an overlapping of addressing in adjacent rows, e.g. the end of a strobe pulse on one row overlaps with the beginning of a strobe pulse on the next row. The display elements may be switched into one of their two states by one of two strobe pulses of opposite polarity. Alternatively a blanking pulse may switch all elements to one state and a strobe used to switch selected elements to the other state.

Title: Method for programming television-game
Inventor: AOYAMA KOJI
IPC: A63F13/45
Filed: 1996-12-12
Abstract: According to a method of programming a TV-game of the present invention, the event variation process is added between processes of the TV-game program. Therefore, one of the processes of the TV-game program or the event variation process is selected according to a situation of a TV-game scenario.      Namely, the event variation process is executed only when the event variation process is selected. The event variation process is not executed when another process is selected.      Therefore, the CPU load is light, because the event variation process is not executed at each time. Further, even if the characters of the TV-game are many, the character motion is not paused. Therefore, the TV-game can include a variety of situations, because the steps in the TV-program are not cut off.
