Filed: 1987-07-07
Abstract: PURPOSE:To largely improve printing speed by forming a heat transfer printing ribbon of a transfer layer and a resistive base layer, and incorporating conductive carbon black and phenoxy resin in the base layer. CONSTITUTION:Conductive carbon black is dispersed in phenoxy resin as a sheet-like resistive base layer, and a transfer layer is provided on one side face of the base layer. If the thickness of the base layer is less than 2mum, its mechanical strength, such as tensile strength is not sufficient, and if it exceeds 30mum, it might be broken by bending, and it is set to 2-30mum. The carbon black of the base layer is preferably 15-50wt.%, and phenoxy resin is preferably 10wt.% or more. If the carbon black is less than 15wt.%, the specific resistance of the resistance layer becomes high, and if it exceeds 50wt.%, it becomes brittle. If the phenoxy resin is less than 10wt.%, its flexibility at ambient temperature and tensile strength at the tire of heating is not sufficient. The resin is of phenoxy resin which is crosslinked by isocyanate.

An automatic centering unit 25 obtains deviations in the directions X, Y of the probe 12 center from the center coinciding with the reference hole S of the spindle and memorizes the deviations az the reference values. And when a workpiece is worked in a required position with reference to another reference hole, the working position is corrected by employing the difference between the measured reference portion value and the reference value for correction amount. Thus, even a plurality of working reference holes can correspond to a single stored reference value to simplify a control unit.

The bubbles adhere onto the digested sludge grains and promote the floatation of the sludge. As a result, the sludge grains swarm on a surface of a solution in the floatation vessel 4. These floating sludge grains are skimmed and carried to a dehydrator 7. The digested sludge may be introduced into a pressure tank 12, compressed there with a compressed gas, and carried to the floating vessel.
