Title: Manufacture of magnetic head
Inventor: KOSEKI HIDEO
IPC: G11B5/23
Filed: 1987-08-26
Abstract: PURPOSE:To improve a manufacture yield by forming a gap member of prescribed film thickness and a soft magnetic thin film forming the other magnetic circuit overlappingly on a gap forming face of core halves to improve the accuracy of the gap. CONSTITUTION:After a nonmagnetic material 4 is imbedded to cover the gap forming face after processing a winding slot 8 while leaving a winding hole 5 on the winding slot 8, the gap forming face is polished. Moreover, SiO2 as the gap member of prescribed thickness is formed by sputtering on the gap forming face and the soft magnetic thin film 2 forming one magnetic circuit is formed overlappingly on the gap member by the sputtering. Thus, the magnetic head block 10 is manufactured in this way and the nonmagnetic holder block 11 is bonded and cut off to obtain magnetic head chips. In the manufacture, since the gap is formed by stacking the thin films in the order of the gap member and soft magnetic thin film, the accuracy of the gap is improved and the manufacture cost is reduced.

Title: Control information communication system
Inventor: ITOU YOSHITAKA
IPC: G08C25/00
Filed: 1982-12-03
Abstract: PURPOSE:To prevent a controller from being failed because of a failure of a service processor transmitting information from a high-order processor to the controller or a transmission line and a transmission line by providing additionally a mechanism checking the normality of a signal from the service processor to the controller and a circuit driving the controller only at the normality. CONSTITUTION:The service processor 2 informs to the high-order processor 1 via a transmission line 5 the setting of the content of operation to an interface circuit 7. When the high-order processor 1 receives this information, the processor transmits a command to a service processor 3 via a transmission line 6 to make the processor 3 read the content set in the FF of the interface circuit 7. The service processor 3 reads the content of the FF in the interface circuit 7 by a signal 18 and informs it to the high-order processor 1 via the transmission line 6. The high-order processor 1 checks whether or not this content is coincident with the operation commanded to the service processor 2 at first, and when a failure is detected, the operation from the beginning is repeated again. When it is decided normal, the service processor 2 applies the power supply of a power supply device 11 via a control signal line 15.
