Abstract: A method and apparatus is provided for dynamic distribution of a communication channel load of sectorized-antennae or omni-directional antennae of cell sites in a cellular radio communication system. The channel load is distributed by narrowing an antenna (102) beamwidth of an overloaded sector of a cell site (100) and widening an antenna (104) beamwidth of an adjacent sector of the cell site (100). In an alternative embodiment, the channel load is distributed by reducing power of an antenna (124) of a cell site (120) which is adjacent to an overloaded cell site (100). Alternatively, the channel load is distributed by increasing power of an antenna (118) of a cell site (116) which is adjacent to an overloaded cell site (100). Subsequent to the channel load distribution, each of the subscriber units in the overloaded (100) and adjacent cell sites (116, 120) are handed off to the particular cell site which is best able to service the subscriber units.

Abstract: A contact plate has at least one of first contact portion provided thereon.  A contact member comprises at least one second contact portion wherein an operating force applied thereto may cause the second contact portion to touch the first contact portion so that predetermined electrical contact is established. The causing of the second contact portion touching the first contact portion results from an operating force elastically transforming the shape of the contact member.  A tilting mechanism functions to tilt the contact member with respect to the contact plate in response to an operating force being applied to the contact member.  The tilting occurs as a result of the tilting mechanism defines a manner of the elastic transformation of the contact member.

Title: Power conversion system, and a method of power conversion using such a power conversion system
Inventor: KONISHI HIROO
IPC: H02M7/19
Filed: 1994-03-11
Granted: 1997-02-25
Abstract: A power conversion system for converting between AC and DC power has a pair of line commutated converters connected in series.  Each is connected to a corresponding transformer, one of which is YY connected and the other Y.DELTA. connected.  A pair of minimum voltage detectors generates minimum voltage signals, a first one of these signals being YY related and the second being Y.DELTA. related.  The system has a control circuit that generates two phase control signals for controlling the pair of converters, respectively.  When a fault occurs in AC or DC apparatus connected to this system, the control circuit generates the phase control signals on the basis of the first and second minimum voltage signals, respectively.  In this way, each of the converters is controlled by an independent signal, so that the power conversion of each is optimized.

Abstract: A galvanized steel sheet has a coating layer of protective material applied to its surface where the steel sheet has been roughened prior to application of the protective material. The improvement is characterized by the roughened steel surface having a pattern which ensures desired consistent quantity of coating during application of the protective material. The pattern provided on the sheet surface has a multitude of depressions defined by a plurality of ridges. The upper surfaces of the ridges defining a plane for each side of the steel sheet, where the ridges have a surface area less than the nominal surface area of the sheet side. Each depression has a depth defined by a continuous side wall extending into the plane of the sheet side.     The side wall slopes downwardly of the plane at an angle greater than 45°.  The multitude of depressions on the sheet side picks up a sufficient quantity of coating material to provide the desired consistent quantity of coating on the sheet surface when solidified and adhered thereto. This improvement in the pattern on the sheet side can increase the amount of protective material provided by 2 to 3 times what can be realized with existing roughened surfaces of steel sheet prepared for galvanizing.

Abstract: Digitized audio information is compressed by retrieving a first audio sample from a digitized audio signal and storing it in its entire, uncompressed, form. The next audio sample is then retrieved and a signed difference between the first audio sample value and the next audio sample value is computed. If this difference value can be represented in fewer data segments than would be required to represent the next audio sample, the difference value is stored, rather than the value of the next sample, otherwise the next sample is stored. The invention proceeds in this fashion until the entire PCM audio signal is compressed and stored. The compressed data stream is decompressed to generate an output data stream by retrieving a stored sample and examining it to ascertain whether it is a difference value or a flag which indicates that the following data represents a coded amplitude value. If the sample is a difference value it is digitally added to the previous value (taking into account the sign) and the sum is inserted into the output data stream. The sum value is retained in order to be used to compute the next output value if the following sample is also a difference value. Alternatively, if the sample is a flag value it is discarded and the next sample is retrieved and inserted into the output data stream.

Title: Portable telephone set tracking connection system in mobile communication network
Inventor: KOYAMA JUNICHI
IPC: H04W76/04
Filed: 1995-02-24
Granted: 1999-12-21
Abstract: A tracking connection system includes a portable telephone set and a plurality of switching units. The portable telephone set receives a calling signal containing a called number and sends a response signal. Each switching unit has a unique management area, in which communication is performed with the portable telephone set, and transmits a calling signal to the portable telephone set present in the management area. Each switching unit includes a memory, a detecting section, and a tracking destination deciding section. The memory serves to store tracking sequence data indicating a sequence for tracking the portable telephone set in advance. The detecting section detects whether the portable telephone set as a calling target is present in the corresponding management area. The tracking destination deciding section decides the switching unit at a tracking destination of the portable telephone set as the calling target on the basis of the tracking sequence data in the memory, when the detecting section does not detect the presence of the portable telephone set.

Abstract: A tube-fitting assembly includes a formed tube, first and second threaded fitting members, and a sealing member. The tube has a first annular bead near an end of the tube and a second annular bead outboard of the first annular bead. The first threaded fitting member surrounds the tube and has a radially inwardly extending first shoulder inboard of the first and second annular beads. The second threaded fitting member has an annular second shoulder at an acute angle to a longitudinal axis of the tube. The second fitting member surrounds the end of the tube and is in threaded engagement with the second threaded member such that the second shoulder engages an outboard side of the second bead to establish a first seal between the tube and the second fitting member against leakage of fluid pressure. The sealing member is a washer or O-ring which surrounds the tube and engages the tube and at least one of the first and second threaded fitting members to establish a second seal against leakage of fluid pressure at temperatures which may relax the second fitting member and break the first seal. In a preferred embodiment the sealing member is made of silicone to maintain the second seal at the relatively high-temperatures.
