Abstract: - ABSTRACT -SEMICONDUCTOR LASER STRUCTURES               A laser structure with highly p-doped active material is described which has a particularly low linewidth enhancement factor .alpha..  Hence the emission linewidth of the laser structure 1 is relatively small.            The structure 1 shows a particular relationship between the photon energy E, the band gap energy Eg and the conduction band quasi Fermi level Efc of the active material which minimises .alpha., the valence band being degenerate.  These conditions can be used to design low  .alpha. laser structures.            Structures according to embodiments of the invention are of particular application to directly modulated lasers or absorption modulators and also find application in coherent optical detection.

Abstract: TITLE OF THE INVENTION    METHOD OF PRODUCING SUPERCONDUCTING WIRE     ABSTRACT OF THE DISCLOSURE    The present invention relates to a method of producing a  superconducting wire  capable  of  obtaining  a  ceramics superconducting wire having a high critical temperature.     Although a ceramics superconductor having a critical temperature of 30K or more has been recently developed, problems have occurred in that the workability is remarkably lowered due to the poor ductility and flexibility, so that it is very difficult to turn into a wire, and the constituent elements other than elements of the group IIa in the periodic table, elements of the group IIIa in the periodic table, cooper and oxygen, which enter superconducting materials as impurities when sintered at high temperatures after giving a desired shape to them to obtain such ceramics superconductor, have a bad influence upon superconducting characteristics such as critical temperature.    The present invention solves the above described problems and provides a method of producing a superconducting wire with a superconducting layer coated with Cu-Be alloys by coating a ceramics superconducting material with Cu-Be alloys and then turning into a wire material having an appointed shape by the area-reduction processing followed by sintering said wire material at a temperature range at which the superconducting layer can be formed.

Abstract: TRANSMISSION CONTROL WITH A CLUTCH PRIORITY VALVE           Abstract of the Disclosure A hydraulic transmission control uses a plurality of solenoid valves to control the engagement of friction devices during the shifting of a transmission between gear ratios.  A clutch priority valve is provided to prevent the continuous simultaneous engagement of friction devices which will establish more than one ratio.  Also provided is a manually controlled valve which permits the operator to determine the range in which the transmission will operate.         If the clutch priority valve has been actuated, the transmission ratio can be controlled between a low ratio, for example, second gear, and a high ratio, for example, third or fourth gear, by use of the manual valve in combination with an actuator mode valve.  The clutch priority valve, when actuated, is also operable to disengage a torque converter clutch.

Abstract: MULTI-DIRECTIONAL SIGNAL TRANSMISSION IN         A BLAST INITIATION SYSTEM     ABSTRACT     The invention provides a connector, a transmitter, a bi-directional device, and a method for increasing the reliability of borehole detonation by using the connectors and transmitters provided by the invention. The invention provides connectors, each connector having a well for receiving a blasting cap, one or more ports or channels for receiving a transmission line and/or downline, and means for joining one connector with another connector in a convenient manner.  The connectors are constructed so that detonation of a blasting cap in one connector will cause sympathetic detonation of a blasting cap in an adjoining connector. The detonation of blasting caps in the connectors also causes initiation of transmission lines and/or downlines which are inserted in the ports or channels through the connectors.  A transmitter is comprised of one or more of these connectors with the transmission lines being arranged so that the transmitter receives a signal from one line and outputs it to at least one other transmission line or downline.  A bi- directional device is provided that consists of a transmission line with blasting caps attached to each end and the caps are inserted into the wells of connectors as described below.  The method of the present invention includes the use of the transmitters and arranging them such that there are at least two signal paths from which a transmitter may receive an initiation signal.

Title: Rotational speed sensor
Inventor: SAKAI KAZUNORI
IPC: G01P3/488
Filed: 1988-07-21
Granted: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE      In order to detect a rotational speed of a rotating body, a cycle time of pulses converted from an electrical signal generated at a rotational sensor is counted.   In determining a cycle of the pulses, either a rising edge or a falling edge of the pulses is selected.  As the selection of the either edge affects accuracy of the rotational speed measurement, two modes are proposed.  One is suitable for a lower speed range in which either of the rising and falling edges is selected for every pulse monitoring period considering the relative phase position of the pulses and the pulse monitoring period.  The other is suitable for a higher speed range in which one fixed edge is utilized.   Here the edge is selected depending on the winding direction of the electric wire of the pick-up coil of the rotational sensor and independent of the pulse monitoring period.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides an improved assay for measuring thyroxine uptake by thyroxine bind-ing globulin in which thyroxine binding globulin (TBG) activity is measured directly.  The method comprises combining a sample in an aqueous solution with an enzyme donor (ED) conjugated to an analogue of poly-iodothyronine that competes with thyroxine for thy-roxine binding globulin binding sites.  An enzyme acceptor (EA) characterized by providing a modulated enzyme activity in relation to the amount of TBG activity is combined with an enzyme donor and sample in an aqueous solution.  The amount of enzyme activity in comparison to a control solution having a known amount of available TBG binding sites is determined.

Granted: 1993-11-09
Abstract: ABSTRACT           A distributed monitoring system is disclosed which may be used for collecting television channel tuning data, household purchase data, VCR channel usage data and the like; on site at a plurality of preselected households, wherein the system concentrates and transmits the collected data to a central site in a fault tolerant manner, transparent to the occupants of the household.  The novel system features a hub and spoke architecture for effecting communications between the central site and each household (remote site).  The hub and spoke architecture at each remote site comprises a hub unit, and a set of spoke meters.  The hub unit is adapted to be coupled, in a variety of ways, to a set of metering devices, one or more of which is coupled to one or more television receivers and/or cable television converters.  Not all of the metering devices need be coupled to the television receiver or cable converter, e.g., stand alone purchase meters and wands may be coupled to the hub.  The meters may be polled systemati-cally, e.g. on a virtually continuous or periodic basis, by the hub, which then collects and concentrates the data acquired by each meter.  As a result of this arrangement standard communications and data transmission "smarts" can be used at the meter level, meter storage requirements are kept to a minimum and no meter communications programming is required.  Additionally, the hub can be easily reprogrammed by downloading control software from the central site without having to modify the meters.

Abstract: Abstract of the Disclosure A high flow sodium chlorate oxygen generator assembly (10) of a relatively small diameter.  The generator assembly includes a chlorate candle (12) mounted within a containment vessel (14, 16, 18), the chlorate candle being provided with a deep conical recess (54) which is thinly coated with a rapidly combustible material (56).  Ignition of the rapidly combustible material is achieved by extending a hollow ceramic tube (58) from a primer (38) located at one end of the containment vessel, the hollow tube directing the flame from the primer, when ignited, towards the center of the deepest part of the conical depression.  The above construction provides a high surface area for burning, and also intensifies the heat flux within the chlorate candle thereby substantially increasing the rate of oxygen output over known chlorate candles of comparable diameters.
