Title: Stator frame for rotary electric machine
Inventor: YAMADA TOYONOBU
IPC: H02K1/18
Filed: 1992-01-20
Abstract: PURPOSE:To eliminate the need of machine work for forming the projecting section of a stator frame so as to improve the adhesion between an iron core and the stator frame by supporting a stator core toward the diametral center of the stator frame and forming a plurality of projections respectively having recessed sections forming thin wall-thickness sections in the length direction on the surface of the stator frame which does not come into contact with the stator core. CONSTITUTION:Projections 4 protruding inward for supporting a stator core 3 are formed on the internal surface of a piece of steel pipe formed by cutting a steel pipe to a prescribed length or rolling a steel plate in a cylindrical shape and welding the seam thus formed. Recessed shapes 7 forming thin wall-thickness sections are formed at the center of the outer peripheral surfaces 6 of the projections 4 on the opposite sides to the contact faces 5 of the projections 4 which come into contact with the outer periphery of the core 3. Because of the recessed shapes 7, the contact faces 5 have projecting shapes 9. The title stator frame is formed by forming such projections having contacts faces 5 with projecting shapes 9 at, for example, six locations on the internal surface of the steel pipe. Therefore, the stator core 3 can be stably fixed to the stator frame 8.

Filed: 1980-01-29
Abstract: PURPOSE:To obtain best tracking with sure operation, by detecting the shift in tracking from the periodical information time relation included in the signal played back with the magnetic head, i.e., clock information. CONSTITUTION:The horizontal synchronizing signal is picked up from the television signal reproduced with a magnetic head 4 via a preamplifier 11, horizontal synchronizing signal separation circuit 12 or the like. On the other hand, the reference signal generating circuit 13 produces the pulse train reference signal having the equal period as the horizontal scanning period in phase- synchronizing with the revolution of a drum. This horizontal synchronizing signal and the reference signal are given to the phase comparison circuit 14 and a control circuit 15, and the control signal is fed to a bimorph plate 7 to deflect the head 4 for a prescribed amount toward the direction in response to the time difference signal. Since the phase relation between the horizontal synchronizing signal and the reference signal reproduced when the head 4 scans is changed according to the tracking of the head 4, the control signal corresponding to this change is fed to the plate 7 for correct tracking. With this constitution, the best tracking can be made.
