Abstract: A method and a device for electrochemically machining workpiece having blade end plates at the longitudinal both ends of a blade-shaped portion having aerofoil shape in cross section by extending and retracting divided electrodes. A part of the blade-shaped portion and one blade end plate continued therewith are electrochemically machined by advancing the main electrode in an acute angle direction relative to the longitudinal direction of the blade-shaped portion. At the same time or subsequently, the remaining part of the blade-shaped portion and the other blade end plate continued therewith are electrochemically machined by slidably advancing an auxiliary electrode along the slope of the main electrode forming an acute angle relative to the blade-shaped-portion-machining-surface. Thus, the number of the parts of an electrode unit can be reduced and the structure thereof can be simplified.

Abstract: Disclosed is a rotation detecting sensor suitable for use under a vibration-abundant condition as e.g. a sensor disposed in an automobile body for detecting rotation of an engine or ABS. The sensor includes a detecting element for detecting rotation of a rotary body as a change in a magnetic flux and outputting a signal and an integrated circuit for processing the amplified signal into a pulse corresponding to the detected rotation of the rotary body. The signal processing includes an initialization such as a gain adjustment for obtaining an appropriate gain for use in the subsequent process of conversion of the amplified signal to the pulse. According to this invention, a re-initialization is effected to obtain a new initial value such as a new gain if the previously effected initialization is determined inappropriate.
