Filed: 1993-03-29
Abstract: In a video telephony system, a coaxial cable network, which is preferably a part of an existing cable television system, provides a local link for the transmission of the video telephone signals between each originating and destination location and a respective "head end" located on the cable company premises. Each of the head ends is connected to a "point of presence" of a telephone interexchange carrier so that a connection between pairs of head ends,and thus between a pair of video telephone locations, can be made via a switcheddigital network maintained by the carrier. Certain of originating and destination locations comprise a standard television set, serving as the audio/video display, and a consumer-type camera or camcorder, serving as the audio/video source. Others of the originating and destination locations comprise ISDN video telephones which are connected to the various points of presence of the interexchange carrier via local exchange carrier telephone networks. The video telephone numbers for cable subscriber locations are administered to be the sameas the standard ten- (i.e., area code plus seven-) digit telephone numbers used for regular telephone calls directed to those locations.

Title: Liquid level monitor
Inventor: MATTIS DONALD J
IPC: G01F23/292
Filed: 1993-07-15
Abstract: A liquid level monitor for sensing the level of liquid in a tank or vessel, typically an automobile radiator, employing a probe with a light emitting diode and phototransistor mounted inside an enclosure, the enclosure having a transparent lens through which light can pass, and the lens having a prism configuration which diffuses or alters stray light which occurs by reflection off an interior core wall of the vessel and prevents the diffused or dispersed light from rendering the phototran-sistor conductive and possibly leading to a false indi-cation or reading of liquid level. The light emitting diode is electrically excited with a high-intensity, short duration pulse, which improves the sensitivity of the monitor. The advantage of the present construction is that there are eliminated erroneous readings result-ing from stray light reflections off internal structures in the tank.

Title: A dielectric isolated high voltage semiconductor device
Inventor: SAKURAI NAOKI
IPC: H01L29/861
Filed: 1993-10-29
Abstract: A new semiconductor integrated circuit uses a dielectric separation substrate for realizing a high withstand voltage and high integration.  The arrangement extends a depletion layer of a main junction beyond an insulating layer sandwiched between a support and semiconductor islands by applying a bias voltage to the support and the islands.  This main junction is a pn junction to which a reverse bias voltage for securing the withstand voltage of the semiconductor element is applied. The impurity density and the thickness of the region between the bottom of the semiconductor island and the circuit element regions is set so that this region is fully depleted by a lower voltage than that at which avalanche breakdown would occur.  For this purpose the distance between the bottom part of the island and the main junction is made less than 1/14V µm when the withstand voltage of the circuit element is V volts.

Patent CA-2112892-A1 (CA)
Inventor: WIRTH JOHANNES
IPC: G01G11/00
Filed: 1993-04-06
Abstract: The bulk material, the amount of which is to be determined through second-integration or time-integration, passes over a top chute (2) onto a bottom chute (3) which defines the velocity of the bulk material. The bottom chute (3) channels the bulk material to a slide (4) which has the same angle of tilt as the bottom chute (3). The weight components of the amounts of bulk material on the slide (4) acting orthogonally along the direction of the slide (4) are determined by a load-sensing device (5). After passing down the slide (4), the bulk material impacts a vertically arranged deflector plate (6) which is rigidly connected to a connecting plate (8), with the deflector plate (6) at that point generating a force through its change in its pulse action which is determined by a second load-sensing device (7). The second load-sensing device (7) only measures the horizontal components of this change in pulse action, and, like the initial load-sensing device (5), is either parallel channeled or provided with parallel channeling.      Both load-sensing devices (5, 7) are connected via lines (11, 12) to a computer (13) which contains the evaluation formula and all relevant correction parameters stored in its memory. Both chutes (2, 3) and the load-sensing devices (5, 7) are supported by a frame (1). Once having been weighed the bulk material falls into a funnel (9).
