Title: Digital automatic line equalizer for communication system
Inventor: YAMAGUCHI MASARU
IPC: H03H21/00
Filed: 1988-07-20
Granted: 1990-11-13
Abstract: Abstract of the Disclosure:     A digital automatic line equalizer for compensating distortion of a digital signal transmitted through a transmission line comprises a transversal filter (11) having a set of tap gains for producing an equalized signal as a filter output from the digital signal incoming thereto.  A first multiplier (200) squares a current one of the filter output to produce a squared signal and other multipliers (201-20?) multiplies the current and the previous ones of the filter output to produce product signals.  A calculator (21) calculates from the squared signal and the product signals a mean value of sum of the squared signal and weighed product signals for a predetermined time duration.  A controller (15) determines a set of values from the mean value to make the set of tap gains equal to the set of values thereby to maintain the mean value to a predetermined value as a reference value so that the transversal filter (11) produces the equalized signal.  The calculator (21) may comprise a plurality of weighing circuits (22) for producing the weighed product signals, an adder (25) for producing the sum, and an averager (26) for producing the mean value.  A controller (15) may comprise a comparator (27) for comparing the mean value and the reference value to produce an error signal, a memory (30) for storing a (Abstract of the Disclosure continued) plurality of sets of values for the set of tap gains, and a selection controller (29) for selecting one of the plurality of set of values in response to the error signal.

Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is a decoding equalizer of high definition television signal transmission mode, such as MUSE, and a subrange-type A/D converter suitable for the equalizer.  The decoding equalizer samples input data in equalization at a frequency twice the sampling frequency of the trunk system, with the equalizing A/D conveter operating at a lower resolution and higher speed than the A/D converter for the trunk system.  The subrange-type A/D converter includes A/D converters in multiple stages, with their driving clock frequencies being in certain relationship so that they are used commonly for the A/D conversion of the high definition television signal and the A/D conversion of a test signal for detecting the transmission characteristics.

Granted: 1998-12-15
Abstract: Novel methods for assaying a nucleic acid analyte are provided, which employ polynucleotides having oligonucleotide sequences substantially homologous to a sequence of interest in the analyte, where the presence or absence of hybridization at a predetermined stringency provides for the release of a label from a support. Particularly, various techniques are employed for binding a label to a support, whereupon cleavage of either a single or double strand, a label may be released from a support, where the release of the label can be detected as indicative of the presence of a particular oligonucleotide sequence in a sample.  The method finds use in diagnosis of disease, genetic monitoring, and analysis of nucleic acid mixtures.

Abstract: TITLE PROCESS FOR THE MANUFACTURE OF 1,4-BIS(4-PHENOXYBENZOYL)BENZENE      WITH A ZEOLITE CATALYST ABSTRACT OF THE DISCLOSURE 1,4-Bis(4-phenoxybenzoyl)benzene is made in a heterogeneous system by a reaction of diphenyl ether with 1,4-benzenedicarbonyl chloride at 190-250-C in the presence of a zeolite catalyst having a ring structure containing 12 oxygen atoms, which can be either an activated zeolite in hydrogen form or an iron-exchanged zeolite, which zeolite can be readily separated from the hot liquid phase in the reaction mixture. The mole ratio of diphenyl ether to 1,4-dicarbonyl chloride, when the catalyst is in hydrogen form, is about 50-80:1: when the catalyst is in iron-exchanged form, it is about 10-50:1; and the weight ratio of 1,4-benzenedicarbonyl chloride to zeolite in hydrogen form is 3:1 to 1:2, while the ratio of 1,4-benzenedicarbonyl chloride to zeolite in iron-exchanged form is 10:1 to 1:2. The product readily crystallizes in a high state of purity from the cooled solution. 1,4-Bis(4-phenoxybenzoyl)benzene is a valuable intermediate in the synthesis of polyetherketone resins.

Title: Remote control
Inventor: THOMPSON DAVID R
IPC: H02J13/00
Filed: 1989-03-23
Granted: 1994-11-22
Abstract: In the field of powerline carrier transmission and reception for remote control, a slave receiver counts cycles of carrier in a time window near to a zero-crossing of the power main.  The receiver is implemented using discrete components (1,2,3) and a microprocessor.  The discrete components form an input filter (1), a limiting preamplifier (2), a demodulator and noise filter (3) and means to detect the zero-crossing points (4).  A capacitor is charged and discharged, depending upon the rate of occurence of carrier cycles to produce a binary signal dependent on the digital value present on the carrier.  By measuring the length of time the binary signal is in one of its states in said time window, the microprocessor determines whether the signal resulted from noise or not.

Title: Generic code sharing arrangement for digital data processing system
Inventor: BRENDER RONALD F
IPC: G06F9/45

Granted: 1993-11-30
Abstract: ABSTRACT OF THE DISCLOSURE A compiler maintains a library of sharable program structures generated in response to instantiations of a generic program structure, along with characteristics of parameters which were used in generating the sharable program structure.  In response to an instantiation of a generic program structure, the compiler generates information relating to the characteristics and usage of each parameter which are used in connection with the instantiation.  The compiler then compares that information to the corresponding information associated with the sharable program structures in the library.  If the library contains a sharable program structure whose parameter information compares satisfactorily, that sharable program structure is used in connection with further operations in connection with the instantiation.  On the other hand, if the library does not contain such a sharable program structure, one is generated and stored in the library, along with the characteristics of the parameters used in its generation, for use in sharing with later instantiations. In addition, the just-generated sharable program structure is used in further operations in connection with the instantiation.

Abstract: Abstract A TECHNIQUE FOR CREATING AND EXPANDING ELEMENT MARKS IN A STRUCTURED DOCUMENT      A method for hierarchically expanding and contracting element marks in a structured document.  The structured document is hierarchically organized, such as documents written in Standardized General Markup Language (SGML).  An element consists of a begin tag and its associated content, and may optionally include an end tag.  The editor can mark an element, to produce an element mark, to indicate its selection for document processing operations such as moving, copying or deleting the content of the element mark.  The element mark can be hierarchically expanded to higher-level element marks by invoking the expand code as appropriate.  The method also can be used to adjust a stream mark to an element mark.

Abstract: A compressor and its external-rotor drive motor are arranged on a common stationary shaft in a unitary housing. On the end of the stationary shaft which is away from the compressor, a friction pump is mounted for pumping lubricant from a supply in the unit housing into an axial canal drilled in the stationary shaft. The impeller of the friction pump consists of a hollow cylinder which is coupled to the external rotor. The hollow cylinder is received in a pump housing which has an annular space between an inner and an outer housing part into which the hollow cylinder extends, forming an inner and an outer gap. The two gaps are in communication with each other and each contains at least one constriction which forces oil carried by rotation of the hollow cylinder past openings in the inner housing into the axial canal.
