A self-inking marking device having adjustable print bands configured to be adjustable by a single adjustment knob, with a readily viewable display for viewing the current status of the print interface. The light-reflective anisotropic conductive adhesive contains a thermosetting resin composite, conductive particles, and a light-reflective acicular insulating particles. Thereby, a predetermined phase relationship can be generated even in cases where no strict phase relation is given between data and reference signal. The multiplier further includes a first carry propagate adder coupled to the plurality of carry save adders and configured to reduce a first and second portion of the redundant product to a multiplicative product during respective first and second carry propagate adder phases. The side wall is connected to a peripheral edge of the bottom and also has a protrusion extending from the side wall, where an upper of the shoe connects to the protrusion.
