Title: Production of magnetic head core
Inventor: ONISHI KAZUMASA
IPC: G11B5/133
Filed: 1985-03-27
Abstract: PURPOSE:To improve the capacity and the mass productivity of a magnetic head by forming primarily a magnetic head core and sintering it preparatorily under specific conditions to form a secondary formed core and forming the secondary formed core under specific conditions by a hot hydrostatic press. CONSTITUTION:A base material powder A is formed primarily into a core B having a prescribed shape by a to die PU and a bottom die PL of a press device 10. The primary formed core B is sintered for 1-5hr at 1,000-1,300 deg.C temperature in an inert atmosphere including vacuum by a preparatory sintering furnace 11. Thus, the density of the primary formed core B is enhanced without deforming to form a secondary formed core C. the secondary formed core C is put in a hot hydrostatic press 20 and is sintered for 1-3hr at 1,000-1,300 deg.C temperature and 200-2,000 atmospheres to complete a magnetic head core D. The shape of the primary formed core B is determined in consideration of shrinkage allowance. Thus, high-capacity magnetic heads are mass-produced inexpensively.

Filed: 1987-03-17
Abstract: PURPOSE:To easily prevent the overload of a supervising controller because of multiplex faults by providing a multiplex fault detection means that transmits a scanning stop signal after the lapse of a prescribed time period in case the number of faults exceeds a prescribed value. CONSTITUTION:In normal status, a fault signal 101 representing the location and the content of a fault detected by a scanning circuit 1 from an inputted fault information signal 100 passes through the multiplex faults detection circuit 2, then is processed by a fault processing circuit 3 from which a fault processing signal 104 is outputted. In case the number of faults within a unit time exceeds a determined value, the detection circuit 2 detects this state and starts its internal timer, and at the same time, transmits a scanning stop command signal 103 to the scanning circuit 1, and further, after the time-up of the timer, restarts the circuit 1 to scan. As a result, during the period in which above-said processes are achieved, the inputting of fault signals 101 into the processing circuit 3 can be blocked, hence the circuit 3 can be prevented from being overloaded.
