  • Publication number: 20110058114
    Abstract: An object-moving mechanism, which makes use of the flow of liquid crystal, is provided. A mechanism for causing a flow of liquid crystal comprising (i) a channel “L” defined by at least one wall surface “B,” (ii) liquid crystal “LC” which is put in the channel “L” and movable along said at least one wall surface “B”, and (iii) a means for turning the molecules “m” of the liquid crystal “LC” in a plane intersecting said at least one wall surface “B.” The mechanism makes use of the flow of the liquid crystal “LC” which is caused when the molecules “m” of the liquid crystal “LC” are turned. When the means for turning the molecules “m” of the liquid crystal “LC” turns the molecules “m” of the liquid crystal “LC” in a plane intersecting said at least one wall surface “B,” the liquid crystal “LC” flows along said at least one wall surface “B.” The flow of the liquid crystal “LC” can easily be utilized for making object-moving devices, sensors, actuators, etc.

  • Publication number: 20100183048
    Abstract: In a communication system including a plurality of pairs of a transmitting device 2 and a receiving device 3, the transmission performance in the pairs is to be improved. The transmitting device 2-k transmits a transmission signal sk(t) to the receiving device 3-k a plurality of number of times. The receiving device 3-k updates the weight matrix Wk and the hopping pattern Pk used by the FIR filter which performs filtering on the transmission signal rk(t) at a predetermined time interval. The receiving device 3-k transmits the updated hopping pattern Pk to the transmitting device 2-k. The transmitting device 2-k receives the hopping pattern Pk to be used for subsequent spread spectrum.

  • Publication number: 20020031260
    Abstract: Concerning feature extraction of documents in text mining, a method and an apparatus for extracting features having the same nature as those by LSA are provided that require smaller memory space and simpler program and apparatus than the apparatus for executing LSA. Features of each document are extracted by feature extracting acts on the basis of a term-document matrix updated by term-document updating acts and of a basis vector, spanning a space of effective features, calculated by basis vector calculations. Execution of respective acts is repeated until a predetermined requirement given by a user is satisfied.
