Title: Etching of metallic electrode
Inventor: IZUMI HIDEAKI
IPC: C23F1/26
Filed: 1979-08-17
Abstract: PURPOSE:To enable etching of Nb or T a metal in high reproducibility and controllability, by particularly reducing the mixing ratio of aqueous hydrogen peroxide to concentrated fluoric acid in a mixed solution of concentrated sulfuric acid, water, concentrated aqueous hydrogen peroxide and concentrated fluoric acid. CONSTITUTION:A metallic electrode containing Nb or Ta as main ingredients is etched by a solution obtained by mixing at volumetric ratio 30-50 of concentrated sulfuric acid, 45-65 of water, 0.2-3.0 of concentrated aqueous hydrogen peroxide and 1.0-5.0 of concentrated fluoric acid. By reducing the mixing ratio of the concentrated aqueous hydrogen peroxide and the concentrated fluoric acid particularly in this manner to suppress the etching rate of semiconductors, insulating films and metals other than Nb and Ta, Nb or Ta may be selectively etched in high reproducibility. If the solution temperature becomes lower than 0 deg.C the etching rate is abruptly decelerated, while if it becomes higher than 50 deg.C, uniform etching becomes impossible, and so it is preferred that the solution temperature is kept in the range of 0-50 deg.C.

Title: Automatic symmetric multi-layer welding method
Inventor: MANABE YUKIO
IPC: B23K9/127
Filed: 1985-05-16
Abstract: PURPOSE:To stabilize quality and to improve efficiency by obtaining the information on a groove with high accuracy by using a non-contact sensor and automating thoroughly the control of welding conditions. CONSTITUTION:The sensor 8 is oscillated in the direction approximately perpendicular to the weld line in front of a weld zone by a specified distance L and a distance signal is continuously fetched in at a micro-pitch. The signal and the sensor position signal are synthesized in an arithmetic unit 12 by which the groove shape is with high accuracy detected. The characteristic point (both shoulders of the groove, the deepest part in the groove) necessary for setting the aiming position in the symmetric multi-layer welding is determined from such groove shape. The sectional area of the unwelded part is then determined. The characteristic point in the groove and the sectional are of the unwelded part are the data of the high reliability from which the influences such as the inclination, waving, flaw, assembly error and spatter of the base metal surface are eliminated. The symmetric multi-layer welding is automatically executed by the techniques for profiling the weld line and controlling the welding conditions using the above-mentioned data having the high accuracy.

Filed: 1978-08-30
Abstract: PURPOSE:To reduce the time required for exchanging work at the exchanging of photoreceptors by coupling the rotary drum and its driving shaft by way of a cam thereby enabling the drum to be freely rotated with respect to the driving shaft. CONSTITUTION:A rotary drum 5 having a sheet-form photoreceptor 6 on the outside peripheral surface is so provided as to be able to rotate independently with respect to a revolving driving shaft.
