Title: Pickup coil for measurement of magnetic fields
Inventor: KAJOLA MATTI JAAKKO
IPC: G01R15/14
Filed: 1991-12-10
Granted: 2001-06-05
Abstract: The invention concerns a pickup coil to measure com-ponents of gradients. The coil consists of two pairs of loops connected in series; these pairs are then connected in parallel. The coil so formed has a low inductance, and no shielding currents are induced to superconducting coils in homogeneous magnetic fields. One coil can be employed to measure several field components simul-taneously when the coil is coupled to current sensing elements, for example to SQUIDs, so that the current components measured by the sensing elements do not couple magnetically because of the symmetry. This can be accomplished by connecting the said elements be-tween terminals between the loops (5, 6 and 7, 8). The inductance of this coil can be further reduced by subdi-viding the loops into party connected in parallel.

Title: Process and device for pulverization and separation
Inventor: NISHIBORI SADAO
IPC: B02C21/00
Filed: 1992-10-22
Granted: 2000-02-22
Abstract: The materials to be treated, for instance, molded resin articles with resin films coated thereon are treated by relatively simple means to separate and remove the resin film coatings from the surfaces thereof, and are further treated to recover them as a raw-form of resin material or a resin material regulated such that its particle diameter lies within a given particle diameter range, or the materials to be treated, for instance, powder materials are pulverized and granulated. A molded resin article is crushed to small pieces, to which compression impacts based on fine vibrations are in turn applied for squeezing, and resin film coatings separated off the small pieces are removed. The thus treated small pieces are further re-pulverized, and frictional crushing impacts are applied to the thus pulverized pieces as well for polishing and size-regulation. Alternatively, directional fine vibrations are applied to one of the inner and outer compression impact surfaces of inner and outer compression impact members that are located in opposition to each other with a given gap between them to pulverize and squeeze the material to be treated that is fed between the compression impact surfaces, thereby separating surface thin films therefrom for granulation.

Filed: 1993-02-03
Granted: 1999-02-23
Abstract: The adaptive bidirectional equalization process of the present invention first determines the point of lowest signal quality for the time slot being processed. Detection is then performed on the time slot in both directions until the processing meets at the point of lowest signal quality.  This process reduces the bit error rate as compared to performing standard equalization on the time slot.

Filed: 1993-03-15
Granted: 1996-01-30
Abstract: A  waveform  shaping  circuit  has  a  waveform equalizer, an envelope equalizer, a slice signal generator, and  a  comparator.    The  waveform  equalizer  serves  to waveform-equalize an optical readout signal, and compensates for interference between code bits.  The envelope equalizer serves  to envelope-equalize  the  output  signal  of  the waveform equalizer.  The envelope-equalized signal is sent from the envelope equalizer to the slice signal generator.          The slice signal generator stabilizes the slice signal.  The outputs of the waveform equalizer and the slice signal generator are applied as inputs of the comparator.   The comparator serves to compare both inputs with each other and produce a binary reproduction signal therefrom.

Abstract: A method of operating a spectrometer to determine property (13) and/or composition data of a sample comprises an on-line spectral measurement (1) of the sample using a computer controlled spectrometer, statistical analysis of the sample data based upon a statistical mode (2, 3, 4) using ample calibration data, and automatically, identifying a sample if necessary based upon statistical and expert system (rule-based) criteria.     Sample collection based upon statistical criteria consists of performing a statistical or rule-based check against the model to identify measurement data which are indicative of chemical species not in the samples already stored in the model. Samples identified either by a statistical criteria or using an expert system (rule-based decisions) are used preferably to isolate the liquid sample using a computer controlled automatic sampling system.      The samples can by saved for subsequent laboratory analysis in removable sample containers. The results of the laboratory analysis together with the on-line spectroscopic measurements are preferably used to update the model being used for the analysis.

Title: Localized surface glazing of ceramic articles
Inventor: MURNICK DANIEL E
IPC: C04B41/86
Filed: 1993-11-10
Granted: 1996-10-01
Abstract: A surface of a  ceramic article,  such as a glazed surface on a whiteware article, is treated with radiant energy such as infrared light from a laser to provide a localized remelting of the material at the surface in a fusing step.   After the fusing step, the surface  is  treated  with  further  radiant  energy, desirably over a larger surface encompassing the fused zone and also desirably at a lower power density so as to limit the rate of cooling of the fusion zone and the immediately  surrounding  regions,  thereby  preventing thermal  stress  cracking.     The  fusion  zone  and surrounding   regions   desirably   are   preheated   by additional  radiant  energy  immediately  prior  to  the fusing step so as to  further limit thermal  stresses during the fusing step.  The process can be employed, among many other uses, for repair of glaze defects and for decoration.

Title: Automatic network element identity information distribution apparatus and method
Inventor: CHAN DOUGLAS W
IPC: H04Q3/00
Filed: 1993-10-25
Granted: 1999-12-14
Abstract: In a telecommunications management network including a network element provisioned as a so-called Directory Services Network Element (DSNE) and at least one sub-network intended to include one or more network elements, the DSNE automatically distributes the identity information of all network elements in a sub-network to all the network elements in that sub-network. Specifically, the DSNE automatically distributes all the identity information for all network elements within a sub-network to a newly registered network element and also supplies the identity information for the newly registered network element to all the other network elements within the sub-network. Since, each sub-network can be defined as a set of network elements that require significant communications with each other, distribution of the identity information for all the network elements in the sub-network to all the network elements in that sub-network significantly reduces the number of queries made to the DSNE. Furthermore, in the event of a DSNE  failure, the network elements in a sub-network may still be capable of communicating with each other, thereby improving communications survivability. (FIG. 1).
