Title: Magnetic head
Inventor: HAYAKAWA YUICHI
IPC: G11B5/11
Filed: 1985-10-16
Abstract: PURPOSE:To accurately record and reproduce the information by setting a ring-shaped conductor of a magnetic head at the outside of two types of coils and also at the inside of the side wall of a slider. CONSTITUTION:Both X and Y directions of the coil side face of the 1st coil 11 are enclosed by the side walls of sliders 2 and 3. While the X and Y directions of the coil side face of the 2nd coil 12 are also enclosed by the side walls of sliders 2 and 3. A ring-shaped conductor 20 is fixed by adhesion to the inside of the side walls of sliders 2 and 3. Thus the sliders 2 and 3 are shielded electromagnetically by the conductor 20 when an external magnetic field is applied from the X or Y direction. This prevents the interlinkage between the external magnetic field and the coils 11 and 12 set inside the conductor 20. In such a way, the accurate information can be recorded or reproduced.

Abstract: PURPOSE:To enhance breakdown strength reaching an erroneous ignition point and to prevent cut-off of the ignition due to induced noises and the like, by providing a third P layer along second P and N layers in a PNPN switch, and specifying the terminal voltage of a gate. CONSTITUTION:A U-shaped P3 layer 14 is provided so as to cover the outer surface of an N2 layer in a PNPN switch and so that the layer 14 is overlapped on a P2 layer. A gate terminal 12 is guided out of the P2 layer and connected to an MOS gate terminal 17 of the layer 14. The layer 14 is connected to a cathode terminal 13 through wiring 15. The voltage of the terminal 17 is made lower than the ON voltage of the P2 layer and the N2 layer. When the switch 1 is turned OFF, the device is operated as P1N1P2P3 transistor against the drastic forward voltage between an anode terminal 11 and the terminal 13. The amplification factor of an N1P2N2 transistor becomes zero. Erroneous ignition is prevented, and breakdown strength is enhanced. Meanwhile, during the time of the ignition a positive bias is applied to the terminal 12, and the layer 14 is changed into an N type. The device is operated as a P1N1P2N3 thyristor, and cur-off due to induced noises and the like is prevented.
