Title: Cutting composite formed of cemented carbide substrate and diamond layer
Inventor: DENNIS MAHLON D
IPC: B23P5/00
Filed: 1992-03-02
Abstract: A composite for cutting in subterranean formations comprises a cemented carbide substrate and a diamond layer adhered to a surface of the substrate.      That surface includes a plurality of spaced apart ridges forming grooves therebetween. The diamond layer has a thickness greater than a depth of the grooves and occupies the grooves to interlock with the substrate.      The diamond layer is comprised of a substantially uniform distribution of diamond particles having a grain size in a range of about 25-75 microns. The ridges are spaced radially inwardly from an outer periphery of the substrate, whereby the diamond layer includes an annular ring portion completely surrounding the plurality of ridges to provide radial reinforcement against the formation and propagation of cracks tending to occur in the vicinity of the ridges.

Title: Clock Synchronizing Circuit
Inventor: NEZU TOSHIYA
IPC: H03L1/02
Filed: 1994-01-26
Abstract: A clock synchronizing circuit comprises a voltage controlled oscillator (VCO) for producing an output signal whose oscillation frequency changes in response to control signals. A phase comparator compares a phase of an input signal and a phase of the output signal to thereby generate a phase difference signal. A filter filters the phase difference signal to thereby output a filtered phase difference signal. A frequency synchronizing circuit responsive to the filtered phase difference signal generates a first compensation signal for controlling a frequency of the output signal. A phase synchronizing circuit responsive to the filtered phase difference signal generates a second compensation signal for controlling a phase of the output signal. A signal supplying circuit feeds the first and second compensation signals as said control signals.

Patent CA-2122449-A1 (CA)
Title: Technique for correcting non-linearity in a photodetector
Inventor: CURBELO RAUL
IPC: H01J43/30
Filed: 1992-10-21
Abstract: A technique that corrects photodetector non-linearity without increasing the noise level in the detector signal. The detector (10) is coupled to a preamplifier (100) characterized by the absence of positive feedback, and the preamplifier signal is communicated to a linear amplifier whose output signal is then digitized. The digitized signal is then transformed according to stored calibration information that is representative of the non-linear characteristic of the photodetector. The transformed digitized value thus exhibits a linear characteristic as a function of the intensity of the light source (180). A number of embodiments perform the correction in hardware before digitizing the signal.

Abstract: A filter for rezeroing an in-vivo pressure sensor is disclosed. The filter operates in a signal mode and a rezero mode. In the signal mode, the filter is a low pass filter which filters out noise. In the rezero mode, the filter is a low pass filter which filters out the dynamic components of an in-vivo pressure signal caused bythe rezeroing of the pressure sensor. The filter is switchable between the signal and rezero modes. The filter is implemented by means of an active two pole RC filterwith a Butterworth response. A circuit is provided to shorten the time in which the filter reaches its final response characteristic. Also disclosed is a method forprocessing an output from an in vivo pressure transducer, the output signal comprising noise, a mean pressure signal and a dynamic pressure signal. The method comprises the steps of: receiving as an input, the output signal from thepressure transducer; filtering out the noise from the received input by means of a first filter circuit; and, filtering out the dynamic pressure signal while passing the mean pressure signal by connecting a second circuit to the first filter circuit.

Title: Thin electronic data input device
Inventor: AMIRI AHMAD
IPC: H01H13/702
Filed: 1995-03-02
Abstract: Conventional computer keyboards if made to a comfortable size for operation, are large and thick, with limited (pocket) portability, expandability, versatility and variety. Numerous moving keys and springs result in reduced reliability (stuck keys), some noise, and vulnerability to drink spills, fall or external shock. This invention is a Thin Electronic Data Input Device which we call "TEDID"for short,comprising an electronic data entry circuitry printed on a thin board, such that finger touching each symbol node on it will send a signal (unique to that symbol)to the receiving computer . The TEDID, being thin can be subdivided into "Sub- TEDIDs" connected by Flexible joints and/or flexible electronic cables, such that the assembly can be folded, some Sub TEDIDs can be removed or stacked . The TEDID can be of flexible material and be rolled or folded, hence pocket size for transport yet full size when unfolded for operation.  No moving parts increases resilience and reliability and washability. One of many of the uses of TEDID is to considerably reduce the thickness of portable computers (such as notebooks) .Another use is to manufacture pocket computers and printers replacing tiny,slow,uncomfortable keyboards with large but foldable TEDID.
