Title: Production of one-side terne alloy plated steel plate
Inventor: HIROMAE YOSHITAKA
IPC: C23C2/02
Filed: 1978-01-26
Abstract: PURPOSE:One side of a steel plate is coated with ultraviolet or electron beam curable resin and the resin is cured, and the coated steel plate is immersed into terne alloy bath, whereby only the uncoated surface is plated with the alloy, providing economically continuous, alloy plated, steel plate. CONSTITUTION:Steel plate 1 is supplied from the payoff roll 2 and its non-plating side is coated with an ultraviolet curable resin using the coater 3. The ocated resin is subjected to ultraviolet radiation from a high pressure mercury lamp 4 and cured. The one-side cured-resin-coated steel plate 1 is then immersed in terne alloy bath 5, in which the alloy reacts with only the resin-uncoated steel surface to cover this surface while the other resin-coated surface is left unplated. The terne alloy plating bath is maintained at a temperature of 300 to 400 deg.C so that thermal damage to the cured resin will not occur. The cured resin which has served for sealing is easily removed in next bonding process by treating for several seconds with 5 to 10% NaOH solution at a temperature of 70 to 90 deg.C.

Abstract: PURPOSE:To completely remove a protrusion irrespective of the size of the protrusion even when the thickness of a semiconductor wafer is irregular by relatively moving a working head at a predetermined interval from the surface of the wafer. CONSTITUTION:A working head 5 diffuses compression fluid from a diffuser 10 opened at a lower surface, and a fine gap is formed between the head 5 and a semiconductor wafer 3. Then, the wafer 3 is rotated clockwise, an arm 7 in which the head 5 is mounted is moved in a direction of moving direction X1 to relatively move the head 5 on the wafer 3, thereby cutting off a protrusion 2.

Abstract: PURPOSE:To stably operate an engine in a collective device of exhaust heat  from the internal combustion engine, by connecting a branch pipe opened to the  atmosphere to an exhaust gas system path between a heat collector and exhaust fan through a control valve opened and closed by a pressure detector signal. CONSTITUTION:If exhaust gas from an internal combustion engine 1 is decreased, also a pressure drop in exhaust gas system paths 2a, 2b connected to a heat collector 4 further to an exhaust fan 5 is decreased, and a head of the fan 5 is left enough. As a result, if back pressure of the engine 1 is decreased, the back pressure is detected by a pressure detector 6, and a control valve 8 is opened through a controller 9 to introduce the atmosphere via a branch pipe 7 to the path 2b and hold the back pressure to constant. Because the atmosphere is introduced in the downstream side of the collector 4, heat exchange performance of the collector 4 is not worsened. In this way, holding of the back pressure to constant can stably operate the engine even if its load is changed.
