  • Publication number: 20090271017
    Abstract: In a machine tool which executes a plurality of programs simultaneously to perform machining, whether or not a precision machining operation period exists in each of the programs is analyzed before machining. If the precision machining operation period exists as a result of the analysis, the start timing and end timing of an ordered precision machining is recognized. Also, at least one of the speed, acceleration, and jerk of a general operation from start timing to end timing in a program for which the precision machining operation period is not specified is lowered. Accordingly, it is possible to provide a machine tool and its program conversion method, capable of performing precision machining with high precision without receiving an adverse effect from other operations, and capable of obtaining good machining efficiency.

    Abstract: This invention provides techniques for a CDMA system having high spectrum efficiency with low transmit power. Each transmitter comprises means of selecting some core-sequences out of multiple sequences to make them convey plural data, means of producing an enveloped selected sequence with such a method as to arrange as guard sequences to a repeated sequence made by repeating each of the selected core-sequences, means of modulating a user specific orthogonal carrier frequency by the enveloped selected sequence to produce a transmit-symbol, and means of transmitting the transmit-symbols. And a receiver comprises means of demodulating a receive-symbol with one of the user specific carrier frequencies to produce a base-band receive-symbol, means of separating respective components corresponding to the sequences selected by the user, by analyzing the base-band receive-symbol with a matrix composed of a channel response vector from the user to the receiver to detect plural data on the components.

  • Patent number: 7216995
    Abstract: A deployable reflector of the invention includes connection members that bridge plural extendable structures constituting a deployable truss structure and connect portions corresponding to nodes of a buckling mode occurring in the extendable structures when a surface cable system is given tension, with portions corresponding to antinodes thereof. The surface cable system includes an internal surface cable system and a circumferential surface cable system connected to the outer circumference thereof. A cable used for the internal surface cable system is high in stiffness and small in ratio of length variation to tension variation. A cable used for the circumferential surface cable system is lower in stiffness and smaller in ratio of the tension variation to the length variation than that used for the internal surface cable system. Given tension by the deployable truss structure via the circumferential surface cable system, the internal surface cable system forms predetermined surface shape.
