Abstract: An electrophotographic plate for making a printing plate is provided. Said electrophotographic plate comprises an electrically conductive and hydrophilic base and a photoconductive layer provided thereon, said photoconductive layer containing an alkali and/or alcohol soluble polymer, a phtalocyanine pigment and a compound represented by the formula (I):(X).sub.n Y (I)where X represents thiobarbituric acid residue from which one hydrogen atom at 5-position has been eliminated and in which nitrogen atom in a ring may have a substituent; Y represents an n-valent substituted or unsubstituted alkylene or aralkylene residue; and n represents an integer of 2 to 4. This plate has high sensitivity and resolving power and from this plate a printing plate of high printing endurance and low printing strain can be made.

Abstract: The disclosed device includes a heater mounted on a plant stem for generating a heat flow Q so as to give a heat supply (Q-Q.sub.o) to water flow in the stem, Q.sub.o being heat loss, a means for controlling heat loss Q.sub.o or heat dissipation through surfaces of the heater and the plant stem at a constant level, a means for measuring difference of the stem temperature between the upstream and downstream ends of the heater, and a means for determining the water flow rate in the plant stem from the above temperature difference and the input power to the heater.
