Title: Manufacture of multipolar magnet
Inventor: TAKAHASHI TSUNETERU
IPC: H01F13/00
Filed: 1985-08-14
Abstract: PURPOSE:To accomplish the magnetization having sufficient strength even when the interval of a magnetized pole becomes very small by a method wherein the first magnetization is performed by abutting the protrusion of a roughened yoke on the surface of a molded body, and then the second magnetization, having the polarity different from that of the first magnetization, is performed by abutting the protrusion on the recess of the roughened yoke of the first magnetization. CONSTITUTION:A direct current or a pulse current is applied to coils 2 and 2', and they are excited in such a manner that both pole pieces 1 and 1' have the same pole. The generated magnetic flux phi moves from the protrusion 5A of an outer pole 3, crosses a formed body 10, enters the protrusion 7A of an internal pole 6, and returns to the pole pieces 1 and 1' passing through a magnetic path. As a result, the same pole (such as N-pole) can be formed on the molded body 10 simultaneously at the prescribed pitch. Then, the molded body 10 is shifted by a pole component against the outer pole 3 and the inner pole 6. A current of the direction opposite to the first magnetization is applied on the coils 2 and 2', and an S-pole is formed between each N-pole formed by the first magnetization. As a result, the multipolar magnet 1 whereon the N-pole and the S-pole are alternately formed can be obtained.

Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To allow the device to surely identify whether or not a signal is a letter box form even when waveform distortion by ghost or the like takes place. SOLUTION: A received video signal is given to an average value circuit 15 via a subtractor 12. The average value circuit 15 obtains a means value of bit areas B1, B2, B3, B4. The mean value depends on a level fluctuation. The means value is integrated by an integration circuit 16, the result is subjected to amplitude limit by an amplitude limit circuit 17 and the result is added to an output of an offset circuit 18, and the sum is given to a subtractor 12. The subtractor 12 cancels the level fluctuation component of the video signal and sets a criterion of a logic value to 0IRE. A bit string coincidence detection circuit 13 decides the logic value according to a sign bit from the subtractor 12 to identify the system of the input video signal.
