A voltage generating circuit that drives multiple output terminals in alternating positive and negative cycles has two resistor ladders, one resistor ladder generating voltages for the positive cycles, the other resistor ladder generating voltages for the negative cycles. Additionally, the light tile includes a bus bar system. Further, by use of the above guidance display, not only a normal person but also a person who has difficulty in hearing can be guided without fail. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle.
