摘要： In a mobile communication terminal for performing wireless communication by receiving wireless signals according to CDMA communication system containing pilot signals by an antenna array containing a plurality of antenna elements (1-1 to 1-N), despreading processing is performed on received signals x1 to XN at each of the antenna array elements (1-1 to 1-N) according to a predetermined despreading code. An array response vector composed of pilot signals which are extracted by an array response vector detecting section for each of the antenna elements (1-1 to 1-N) represents the arriving direction of wireless signals. In order to form a directivity pattern of the antenna array containing antenna elements (1-1 to 1-N), a weighting operation is performed according to the array response vector. By doing this, it is possible to control the antenna array directivity pattern stably for performing wireless communication by receiving wireless signals according to a CDMA communication system.

摘要： To realize an adaptive antenna array system which improves reception quality of desired signals by properly suppressing interference signals. The system includes: a signal detection section which detects base station signals from signals received by antenna elements; a control section which selects desired signals and interference signals to be cancelled from among the detected base station signals; a spatial signature detection section which detects spatial signatures of the desired signals and the interference signals to be cancelled; a virtual-signal generation section which generates virtual-signals for the interference signals to be cancelled using the spatial signatures thereof; an array weight generation section which generates array weights for the antenna elements by multiplying the inverse matrix of a correlation matrix of the virtual-signals by the spatial signatures of the desired signals; and a signal combining section which combines the received signals using the array weights.

摘要： A nozzle to be connected between a conventional molding machine and a mold cavity for injecting molten resin of thermoplastics into a mold cavity where a gate at the front end of a cylinder of the nozzle opens and closes automatically according to the pressure of molten resin. A differential moving piston slidably disposed in the cylinder includes a front piston and a rear piston mounted on the front end and the rear end thereof respectively, a passage for molten resin axially drilled therethrough and a needle protruding forward from the front end of the front piston for mating with the gate according to the sliding movement thereof. A spring disposed in the cylinder pushes the differential moving piston forward to close the gate. Herein said front piston is larger in its effective area functioning as a piston head than that of said rear piston so that when the pressure of molten resin increases the differential moving piston slides backward to open the gate against the spring by the backward pushing differential force between the total pressure on the front piston and the total pressure on the rear piston.
