摘要： To provide a coil bobbin for a transformer in which no through hole is formed in both sides of an upper flange to thereby prevent upsizing, and no long arm apt to splinter is formed on a terminal board, and the terminal board can be readily mounted to a flange. In the coil bobbin in which an end of an upper flange (3) formed on an upper end of a drum (2) is formed with a terminal board mounting portion (5), and in which a separately formed terminal board (8) is mountable on the terminal board mounting portion (5), an inside of the terminal board mounting portion (5) is formed with a rib (7), whose upper portion is formed with a plurality of plate-like walls, and an inner end of the terminal board (8) is formed with a plurality of through holes (17) in which said walls are inserted.

摘要： In a thermal cutting machine provided with an NC system of the type having a manual pulse generator allowing the operator to manually adjust the working head height from a workpiece a profile control apparatus is provided to maintain a reference distance between the head and a non-flat workpiece. The profile control apparatus is installed in the cutting machine, by adding only a head distance sensor and a Z-axis controller in parallel with the manual pulse generator via a selector switch. The Z-axis controller generates a pulse signal having a frequency proportional to a differential voltage between a reference head height determined by the NC system and an actual head height detected by the head distance sensor to correct the reference head height from the non-flat workpiece. The V-F conversion characteristics of the Z-axis controller are of Z-type, in particular, to reduce the profile error.
