Abstract: Scanning welding heads are introduced through respective openings of a workpiece into the workpiece by respective welding robots.  When a laser beam is emitted from a laser beam emitting device, the laser beam is applied to a beam splitter of one of the welding robots, which reflects about 50 % of the energy of the laser beam and introduces the laser beam into a scanning welding head.  The beam splitter passes the remaining 50 % of the energy of the laser beam therethrough.  The laser beam that has passed through the beam splitter is reflected by a totally reflecting mirror of another scanning welding head.  The scanning welding heads apply the laser beam to respective regions in the workpiece to weld the workpiece.

Title: Apparatus for detecting arcing faults and ground faults in multiwire branch electric power circuits
Inventor: ELMS ROBERT TRACY
IPC: H01H83/02
Filed: 2000-03-10
Granted: 2008-12-30
Abstract: A multiwire branch circuit including two line conductors and a grounded, common neutral conductor is protected by a two pole circuit breaker connected to independently interrupt overcurrent conditions in the two ungrounded line conductors. Three separate protection circuits provide arc fault protection for each of the ungrounded line conductors and ground fault protection for all three conductors. The arc fault detectors us e the bimetal of the thermal-magnetic trip device for the associated line conductor for current detection, and therefore, are individually referenced to the associated line voltage. Hence, the outputs of the arc fault detector s are electrically isolated from each other and from the output of the ground fault detector, but operate a common trip circuit to simultaneously open both poles of the two pole circuit breaker. The arc fault detectors have separate isolated power supplies. The ground fault detector is powered by a supply which is energized if either of the ungrounded line conductors is energized.

Abstract: The present invention provides a method and apparatus for preventing show-thru (and therefore misinsertion of unintended traffic) among uplink beams transmitted to a satellite. The method includes the steps of selecting (402) an uplink A stagger value, selecting an uplink B stagger value, coding (404) uplink A data to generate coded uplink A data, and coding (406) uplink B data to generate coded uplink B data. Subsequently, the method transmits (412) the coded uplink A data, staggered by the uplink A stagger value, in the uplink A and further transmits (414) the coded uplink B data, staggered by the uplink B stagger value, in the uplink B. During coding (404, 406), the method may use a full length error correcting code capable of correcting t errors. In such a case, the method generally selects an uplink B stagger value differing from the uplink A stagger value by more than t codeword symbols. Alternatively, the method, during coding (404, 406), may use a shortened error correcting code capable of correcting t errors. In such a case, the method generally selects an uplink B stagger value differing from the uplink A stagger value by at least one codeword symbol. The method is not limited to any particular number of uplink beams and may provide staggering for all same color uplink beams in a predetermined reuse pattern, for example.

Abstract: A digital broadcasting receiver is provided which can reproduce a carrier quickly and capture a desired signal at high speed. A carrier reproduction phase error detection circuit (6) detects a phase error voltage in accordance with a demodulation output obtained by demodulating a demodulated wave of a modulated wave during a predetermined section in a header section. A peak number calculation circuit (92) calculates an error frequency between a desired reception frequency and a reproduction carrier frequency in accordance with the phase error voltage. A differential coefficient calculation circuit (94) calculates the polarity of the error frequency. A step frequency control circuit (96) converts the calculated error frequency having the calculated polarity into a step frequency width for automatic frequency control. The reproduction carrier frequency is scanned at the converted step frequency width until a frame sync is established after the frame sync is detected. It is therefore possible to reproduce the carrier quickly and capture the desired signal at high speed.

Abstract: A high purity chemical-free microcrystalline cellulose having a low degree od polymerization can be obtained by a process that does not require the use of any acids such as HCl, H2SO4 as are needed in conventional acid hydrolysis processes. This process comprises the steps of preparing a pulp by repulping, filtration and trituration of a chemically produced cellulose. The so-prepared pulp is subjected to heating through a steam explosion treatment in order to obtain a treated pulp. A shearing force is applied onto the pulp at the end of the steam treatment. The treated pulp is then filtered, washed and bleached thereby to obtain the high purity chemical-free microcrystalline cellulose.  With this process, one may produce chemical free microcrystalline cellulose by using chemically produced cellulose such as kraft or bisulfite cellulose as starting material. The high purity microcrystalline cellulose obtained from the present process may be used in the pharmaceutical and nutritional industries.
