Title: Magnetic head

IPC: G11B5/29
Filed: 1994-06-09
Abstract: PURPOSE:To obtain a magnetic head with which a high C/N and high density recording are obtainable by providing this magnetic head with conductors near the gap part in a track width direction. CONSTITUTION:Magnetic flux of a high frequency flows in direction D when recording current of a high frequency is passed to a coil 7 wound to enclose a head core 2 and a head core 3. consequently, the leak magnetic flux is generated in direction E in the gap part 4 at the front end. Recording of signal on a magnetic tape is executed by bringing the magnetic head into contact with the front end of the magnetic head and moving the tape or the head. At this time, the magnetic head is provided with the conductors 5, 6 near the gap part in the track width direction and, therefore, a large eddy current is generated in the conductors 5, 6 to hinder the magnetic flux when the high-frequency magnetic flux tends to flow toward the conductors 5, 6 from the head cores 2, 3. The flow of the magnetic flux toward the conductors 5, 6 is thereby prevented and, therefore, the magnetic head which does not generate the leak magnetic flux in the tack width direction and is capable of the high output and high density recording, is realized.

Abstract: PURPOSE:To reliably detect whether or not an object to be filled has been put into a bag in an intermittently table rotating bagging and packing apparatus equipped with a bearer provided for supporting a lower part of the bag at a position for putting the object. CONSTITUTION:A plate 19 which can freely rock is attached to an elevating frame 17, and a bearer 10 is attached to an end of the plate 19 to always apply force to the plate 19 by a spring 21 toward a head of a stopper 20.
