A duplex printing instruction is accepted. The patch is of such a thickness as to substantially attenuate radiation by distance or consists of a material that has been formulated with radio-attenuating filler or is of radio-attenuating material. Using the set transmission power value, the base station apparatus transmits a transmit signal of the set transmission rate to a communication terminal apparatus. The feeder device, the metering device and the nozzle are adapted for applying strands to the receiving surface in the form of an elongated bead. The switch may switch from the second pulse train to the first pulse train and substantially maintain the first edge sharpness of the first pulse train during a low value of both the first and second pulse trains.
