Abstract: To provide a thin wideband antenna unit capable of shrinking the size of a radiation element in a case where a dielectric is not used. In a wideband antenna unit 10 having a ground plate 12 and a flat shaped radiation element 14 disposed on a plane (x, y) flush with a plane where the ground plate extends, the radiation element 14 has an elliptically shape. The radiation element 14 and the ground plate 12 are apart from each other by a predetermined feeding distance ?FD. A ratio between an outside diameter 2aout in an ellipse's x-direction and an outside diameter 2bout in an ellipse's y-direction is 8:5. The elliptically shaped radiation element 14 has an elliptically shaped opening 14a which is concentric O with the elliptically shape. An inside diameter 2bin in the ellipse's y-direction is half of an outside diameter 2bout in the ellipse's y-direction.

The circuit board (25) has a rear surface (25L) provided with a 90-degree phase shifter formed thereon.

Abstract: An antenna unit consists of an EBG reflector, a single curl antenna supported at a central portion of the EBG reflector, and a periodic structure upper plate disposed apart from a principal surface of the EBG reflector by a predetermined distance. The EBG reflector includes a substrate having the principal surface and (Nx×Ny) square patches which are printed on the principle surface of the substrate and which are arranged in a matrix fashion (lattice structure). The periodic structure upper plate consists of a film and (Nx×Ny) square patch-like conductors printed on the film. The (Nx×Ny) square patch-like conductors are disposed so as to oppose to the (Nx×Ny) square patches, respectively.

The first antenna pattern and the second antenna pattern are disposed so as to be opposed to each other through the board with they electrically disconnected.

Abstract: Each of D flip-flops (FFs) 13a to 13f constituting a scan path circuit has a normal operation input circuit to be selected in a normal operation and a test operation input circuit to be selected in a test operation, and a control signal having an intermediate voltage between a supply voltage and a ground voltage is sent from a voltage generating circuit 17 to the test operation input circuit of each FF in the test operation. In this case, the amount of an output change in data in each FF is smoother than that in the case in which the supply voltage is applied. Consequently, the delay time of the data is increased. The intermediate voltage to be applied to each FF in the test operation is determined based on a feedback signal sent from a test circuit 15 for checking whether scanned-out data have an error or not.

Abstract: A data processor has sixteen processing elements that each include a register file and an arithmetic logic unit. A network unit connects between the register files of the processing elements and the arithmetic logic units of the processing elements. The network unit has a selector for simultaneously performing a plurality of data transfers which are each made from a register file of one processing element to an operation unit of another processing element. With the provision of this selector that can perform such simultaneous data transfers, the processing efficiency of the processing elements can be maintained even if a change occurs in operand assignments and the like.

Abstract: An electric-wire guide unit is provided with a fixed roller and a movable roller that is supported movably toward and away from the fixed roller, and holds an electric wire from both of the sides of the electric wire in cooperation with the fixed roller. An electric-wire nozzle unit is provided with a fixed nozzle guide and a movable nozzle guide that is slidably placed, and forms a nozzle opening through which the electric wire is inserted, in cooperation with the fixed nozzle guide.

An tension spring, which presses the movable roller in an approaching direction toward the fixed roller, is attached. In accordance with the size of the diameter of the electric wire to be held between the movable roller and the fixed roller, the movable nozzle guide is slide-operated through the link mechanism so that the nozzle opening is size-adjusted.
