Filed: 1978-07-24
Abstract: PURPOSE: To reduce the iron loss of a rotor by making a magnetic flux density distribution of the rotor uniform.  
     CONSTITUTION: When a gap between main core 2 and rotor core 4 is g, a cross-section of magnetic flux passing of main core (eq. a cross-section perpendicular to radial direction) is S 1  and a cross-section of magnetic flux passing of main core piece 2A (eq. a cross-section perpendicular to circumferential direction) is S 2 , g is set 0.8mm and less than 0.8mm and S 2 /S 1  is set 16∼20%. In comparison to S 1 , if S 2  may be too great or small, in general, the magnetic flux density is locally increased and the iron loss may be increased because it is proportional to substantially square of the magnetic flux density. This phenomenon can be found also when the gap is narrow. These relationships can be made clear by a characteristic curve as shown in the figure. As indicated in the figure, the iron loss can be reduced when g≤ 0.8mm, S 2 /S 1 =16∼20%.

Filed: 1983-05-21
Abstract: PURPOSE:To correct a phase shift caused in a reproduced component signal by changing a phase shift produced in the reproducing signal when each head moves on a scanning track so as to correct an address number of an address signal. CONSTITUTION:A phase shift of 1.5H's share is produced at each movement of head from one track group to the next track group by heads 1R-1G2. This phase shift is corrected by applying time correction through the switching operation of switching circuits 28B, 28G1 and 28G2 when each primary color signal is written from memories 21R-21G2 in a line address sequence control circuit 22. Then, the compensation is attained so as not to produce substantial color offset to a color signal S6 obtained from a decode circuit 13. Thus, the deterioration in the picture quality is compensated effectively.
