Abstract: PROBLEM TO BE SOLVED: To obtain a highly efficient motor having a good magnetic characteristic by forming an annular magnet integrally with a yoke by press-fitting the magnet in the yoke. SOLUTION: The yoke 33 of a motor has a step section 33B on its inner peripheral surface 33A and an annular magnet 34 having an outside diameter which is slightly larger than the inside diameter of the inner peripheral surface 33A is formed integrally with the yoke 33 by press-fitting the magnet 34 in the yoke 33 by means of a press-fitting jig 4.

Title: Programmable control circuit for radio or television receiver or either one thereof
Inventor: HANSU HOFUMAN
IPC: G04G15/00
Filed: 1983-11-22
Abstract: When programming a radio and/or television receiver for future transmissions, problems may occur due to overlapping of the programmed transmissions. For this purpose the individually programmed transmissions are provided with priority data which control the sequence in the event of overlapping transmissions. In the same way given transmissions can also be provided with blocking data which block the reception or reproduction, respectively, thereof. The use of the priority data is particularly efficient when the transmissions are controlled in addition or exclusively by transmitted identification numbers and consequently are only received during the actual transmission time, as then shifts with respect to the planned transmission times cannot be foreseen. Additional possibilities are derived from the storage of data characterizing the type of the transmission, when these data are transmitted simultaneously with the relevant transmission.
