Title: Doctor blade for gravure printing
Inventor: KAMETAKA ATSUSHI
IPC: B41F9/08
Filed: 1994-11-18
Abstract: PURPOSE:To prevent the burr at the edge of a blade and the like from developing and enhance the stability on gravure printing by a method wherein stocks equipped with the difference in hardness or in wear are laminated to each other at the rear surface of the edge of the doctor blade. CONSTITUTION:In a doctor 1 for gravure printing, the part B' wears without developing burr at the same wearing rate as the wear the part C' due to the resin layer 5 coated on steel material 3, which acts as an original doctor and has the Vickers hardness of 580. Next, as for the resin coating layer 5, due to its low hardness, the layer 5 easily wears together with the wear of the surface A'. At the same time, the tip part E' wears evenly even under the low doctor pressure or falls off in fine fragments. Since the doctor blade 1 has two-layered structure so as to realize even wear at both its front surface side and its rear surface side by coming into contact with a gravure plate, the tip on the rear surface side also evenly wears, resulting in developing no burr at the tip part and accordingly preventing printing troubles such as feathering, arrow mark and the like from developing in printing.

Abstract: PROBLEM TO BE SOLVED: To make easier confirmation of power supply connection when installing a power conversion equipment, by providing means for judging the phase sequence and power conduction or power interruption within a power conversion equipment. SOLUTION: A three-phase AC power supply 1 has U, V, and W phases, voltage detection means 2a is located between U and V, voltage detection means 2b is connected between W and V, and outputs from these are connected to a power supply state computing element 4. And the output of Vq computing element 5 possessed by a power supply state computing element 4 is inputted to a state judging means 6 of a power supply and its output is connected to a power conversion equipment 39. If Vq is a constant value, then the phase sequence of the three-phase AC power supply 1 is in the order of U phase →V phase → W phase.  If Vq is a sine wave form where the positive and negative wave heights are equal, then the phase sequence is in the order of U phase → W phase → V phase, and if the Vq vibrates in a sine wave form with positive and negative values, with a positive offset, then the U phase or W phase is considered to be grounded and thus handled as a power interruption state.
