    摘要: For producing an abrasive tape (11) including a film substrate (2) and a polishing abrasive layer (10) laminated on one surface of the film substrate (2) and having on the outer surface thereof a plurality of recessed parts (9), the film substrate (2) is wrapped partially around the outer peripheral surface of a roll formplate (1) having on the surface thereof a plurality of concavities (5), and, as the roll formplate (1) is rotated, the film substrate (2) is fed thereto. On one hand, an ionizing radiation curing type resin (3) is supplied into the interface between the roll formplate (1) and the film substrate (2) therearound to be formed by the concavities (5), and the recessed parts (9) are formed on the resin surface. During this forming, radiation rays (R) are projected from an ionizing radiation ray source (8) toward the resin (3) thereby to cure the resin (3) and, at the same time, to render the resin (3) and the film substrate (2) into an integral structure. The abrasive tape (11) obtained in this manner is separated from the roll formplate (1). The abrasive tape (11) thus obtained is of high product quality. The production method is highly efficient and is suitable for mass production of abrasive tapes of identical concave-convex surface figuration.

    摘要: A label having a sublimation transferred image constituted of an image-receiving sheet, comprising a tacky layer, a sheet substrate and an image-receiving layer laminated in this order on a peeling sheet. The tacky layer, sheet substrate and image-receiving layer form a label portion, and the image-receiving sheet has a structure peelable between the label portion and the peeling sheet. The label has one or more frames of sublimation transferred images formed by transfer of a sublimable dye in a colorant layer of a heat transfer sheet by heating according to an image information. The label portion is applied with half-cut treatment with cutting lines for sectionalizing every frame of the sublimation transferred image.

    摘要: A diversity system using a phase control circuit for combining respective outputs of a plurality of routes of different path lengths transferring the same analog signal. An analog variable delay circuit, which is capable of controlling its amount of delay by varying the repetition frequency of clock pulses, and a low-pass filter connected to the output of the analog variable delay circuit are inserted in each route other than a reference one of the plurality of receiving routes. A phase difference between the output signal of the low-pass filter and the signal of the reference route is detected. The repetition frequency of the clock pulses is controlled by the detected phase difference for controlling the analog variable delay circuit in a manner to reduce the phase difference, so that the phase difference between the respective output signals of the plurality of receiving routes is substantially negligible to allow combining the output signals. An analog variable delay circuit, whose delay time is controlled by the above clock pulses, is inserted in each route other than a reference one of a plurality of transmitting routes passing through the same transmission medium as the above receiving routes. The diversity in the transmitting routes is accordingly achieved.

    摘要: A circuit for compensating for the nonlinearity in a high-frequency amplifier, in which a pair of a first transmission line and a second transmission line respectively have a delay line and a nonlinear distortion generating high-frequency amplifier. An input signal is divided into two signal parts, which are respectively applied to the first transmission line and the second transmission line. The vector sum of respective outputs of the first transmission line and the second transmission line is obtained to provide a nonlinear characteristic for compensating for the amplitude and phase nonlinear characteristics in the high-frequency amplifier connected in cascade to this circuit.
