Title: Armature core
Inventor: UENO NOBUHITO
IPC: H02K1/16
Filed: 1993-04-06
Abstract: PURPOSE:To reduce the iron loss of the armature of a commutator motor by relax the saturation of magnetic flux at the tooth tip parts of the armature core. CONSTITUTION:This armature core is composed of a yoke 1 having an inner hole in the center, and a plurality of teeth 7a and 7b having T-shaped claws at their tip parts extending radially from the yoke 1, and the breadth of each tooth is made gradually wider toward the periphery. And a winding aerial wire 4a for a coil wound between slots 3a and 3b and a winding aerial wire 4b for one wound between slots 3a and 3c are formed. This shape makes it possible to widen the breadth of the tip parts of the teeth by utilizing parts of the slots incapable of being occupied by the armature windings. Accordingly, it becomes possible to relax magnetic saturation because of magnetic flux concentration at the tip parts of the teeth of the armature core without lowering the space factor of the armature winding, and reduce the iron loss of the armature.

Abstract: PURPOSE:To correct a discontinuous reproduction to a reproduction signal free from noises by using a connecting means which connects plural discontinuous signals to produce a continuous signal in response to a switching action of a reproduction head, a delay means, a correction means, etc. CONSTITUTION:A pulse J is produced synchronously with revolutions of head 3 and 4 and supplied to the 1st and 2nd MFFs 25 and 26. While a pulse M1 is supplied to BFFs 27 and 28 and produces signals B1 and B2. The signal B2 is set at L when the signal B1 is set at H, and a reproduction head is switched to obtain the reproduction signals W1 and W2 from heads 3 and 4. Then signals W1 and W2 are synthesized by a mixing circuit 13 and demodulated to a signal W3 through an FM demodulator 15. The signal W3 is turned into a signal W5 at the output of the 3rd switch 9. Both W3 and W5 have the same waveform. The output impedance of the 4th switch 10 is extremely reduced and the time constant of an accumulator 20 is reduced satisfactorily. As a result, both signal W4 and W6 have the same waveform. This reduces the noises which are produced when the discontinuous signals are connected and improves the quality of a reproduction signal.
