Title: Method and apparatus for erratic doppler frequency shift compensation
Inventor: TAYLO DANIEL RICHARD
IPC: H04B7/185
Filed: 1997-07-10
Abstract: Erratic or unpredictable motion of a portable communication unit (110, fig.1) in a system having base and portable communication units (105,155 and 110, fig.1), produces Doppler frequency shifts which cannot generally be predicted or calculated using standard Doppler frequency offset generation. To compensate and track erratic Doppler frequency shifts, changes in the velocity vector of the portable unit are measured to provide differential velocity vectors which can be incorporated into the standard frequency offset generation. The velocity vector of the portable unit may be calculated using global positioning systems (GPS) or other standard methods. The standard frequency offset generation may be supplemented with the differential velocity vector once a tracking threshold level is exceeded, the threshold being either a velocity change, Doppler frequency shift or acceleration threshold. Alternatively, the standard frequency offset generation may be continuously supplemented without applying a threshold. The system has applications in aeroplanes and high speed trains.

Title: I.c. engine valve seat made from sintered Fe alloy
Inventor: OSHIGE HIROSHI
IPC: F01L3/04
Filed: 1997-12-22
Abstract: A process for manufacturing a valve seat which is made of a sintered Fe alloy and comprises a main layer of a valve seat and a contacting layer, comprises the steps of preparing either a powdery Cu or a powdery material containing Cu in a powdery Fe alloy, forming a green compact body with two green compact body layers, one of which is the main layer and the other of which is the contacting layer, and which are made of the prepared powdery Fe alloy containing Cu, sintering the green compact body. According to the present invention, the infiltration of Cu from the main layer to the contacting layer of the valve seat is not generated as the conventional sintering process for manufacturing the valve seat comprising the two layers without the independent infiltration treatment of Cu, and, therefore, the valve seat obtained of the present invention has an high abrasion resistance without decreasing of a strength of the main layer.

Title: Cordless telephone operating in public and private telephone systems
Inventor: OGATA SHIGERU
IPC: H04W48/18
Filed: 1998-01-29
Abstract: A base station of a private telephone system transmits incoming call signals intermittently at a frequency f1 and timing t1. A base station of a public telephone system (for example PHS) transmits incoming call signals intermittently at a different frequency f2 and timing t2. A cordless telephone operating in the private system performs intermittent reception at the frequency f1 and timing t1. If reception quality deteriorates then in the periods between intermittent reception the cordless telephone scans for the intermittent signals from the public system. The quality of reception of the public system is compared with that of the private system and if better the cordless telephone switches to the public system and intermittently receives at a frequency f2 and timing t2. Switching is also executed in a period between intermittent reception. Switching back to the private system is achieved in the same way.

Title: Flat panel display apparatus video data processing system
Inventor: KIM SE-YONG
IPC: G09G3/28
Filed: 1998-04-29
Abstract: A flat panel display apparatus eg a plasma display panel, and a method for processing video data thereof are disclosed. The method includes a first step of inputting N bits of sample data of respective red, green and blue in parallel 12a-12c, outputting inputted N data in series and rearranging 14a the inputted N data to N units of 1-bit data of respective red, green and blue. A second step 14b is storing a word in a memory in the word of unit in which among respective N units of 1-bit data with respect to rearranged red and blue, N/2 units of 1-bit data in an odd-numbered sequence are placed at an upper bit while N/2 units of 1-bit data in an even-numbered sequence are placed at a lower bit, and in which among N units of 1-bit data with respect to a rearranged green, N/2 units of 1-bit data in an odd-numbered sequence are placed at a lower bit while N/2 units of 1-bit data in an even-numbered sequence are placed at an upper bit. A third step is reading out simultaneously both upper 3N/2-bit data generated by combining upper N/2-bit data and lower 3N/2-bit data generated by combining lower N/2-bit data among a word of respective red, green and blue stored in the memory. A fourth step 14c includes the substeps of storing the upper 3N/2-bit data read out from the memory in harmony with an arrangement order of red, green and blue electrodes required by an upper address electrode driving section in a first storing area of a data interfacing section, and provisionally storing the lower 3N/2-bit data read out from the memory in harmony with an arrangement order of red, green and blue electrodes required by a lower address electrode driving section in a second storing area of the data interfacing section at the same time. A fifth step is outputting data stored in the first and second storing areas to the upper and lower address electrode driving section in sequence, respectively. Therefore, line patterns between the memory and the data interfacing section are simplified.

Title: Preventing sparking of electrical connectors
Inventor: REED NORMAN
IPC: H01R13/622
Filed: 1998-10-02
Abstract: Pins 20 are brought into electrical contact with sockets 18 by a thread 54 of a connector housing 26 rotating on a thread 56 on a socket housing. A rearwardly and outwardly diverging surface 60 on the socket housing is first aligned with the O ring 42 and then engages with an O ring 44 to seal therewith and compress that ring. Subsequent to the O rings being so engaged, further axial advancement causes the pins to make electrical contact with the sockets. The region that the pins and sockets have in common is sealed from the ambient surroundings by the interiors of the pin housing 24 and the socket housing 52 and by the O ring seals 38 and 44 and also by the interior of the ring housing 32. The resilience of the O ring seal will enable any explosion in that region to be contained with the resilience of the O ring seals assisting in absorbing the initial expansion on ignition.

Title: Multipart reinforcement bar especially for reinforcement, jumping bars, anchoring bars and others
Inventor: AICHER MAX
IPC: E04C5/12
Filed: 1993-12-03
Abstract: A multipart steel bar, in particular a concrete-reinforcing bar, comprises two identical bar pieces (2, 3) which have an approximately oval cross-section and a thread-like, corrugated profiling (10) on the curved side surfaces. The bar pieces (2, 3) are arranged such that they are parallel to one another and make contact with one another in the longitudinal direction in such a manner that a corrugation peak of one bar piece (2) comes to lie in a corrugation valley of the other bar piece (3), said bar pieces (2, 3) forming an overall cross-section with a circular envelope. At least over sub-regions of their length, the bar pieces (2, 3) are fixed by an enclosing device (14) which prevents the bar pieces from separating from one another under loading and may exhibit a corresponding internal thread. The reinforcing bar thus forms a reinforcing element which, although it can be handled as a single-part system, is a multipart element, in the case of which the bar pieces, as a result of the profiling on their inner contact surface, undergo a mutual positively locking connection over their entire length, this permitting, in the installed state, a redundancy of the reinforcing elements which has been unknown in the building industry hitherto. <IMAGE>

Title: Tie, a nocel endothelial cell receptor tyrosine kinase
Inventor: PARTANEN JUHA
IPC: C12N9/12
Filed: 1993-01-08
Abstract: The cloning, sequencing and expression of a novel receptor tyrosine kinase, termed tie, is described. The tie precursor comprises 1138 amino acid residues, about 1117 residues of which comprise the mature tie. The tie extracellular domain contains distinct stretches of amino acid sequence having features of the imunoglobulin, epidermal growth factor and fibronectin type III repeat protein families. Alternative splicing creates variants of tie which lack one of the epidermal growth factor homology domains. A specific tyrosine phosphorylated 117 kD glycoprotein is detected by specific tie-antisera from cultured cells expressing the tie gene. The tie mRNA is expressed in cultured endothelial cells as well as in a few tumor cell lines. In situ hybridization of human fetal and mouse embryonic tissues shows specific expression in endothelial cells of blood vessels. The tie DNAs and polypeptides of the invention may be useful in the diagnosis and treatment of certain diseases involving endothelial cells and their tie receptor such as neoplastic diseases involving tumor angiogenesis, wound healing, thromboembolic diseases, atherosclerosis and inflammatory diseases.
