Title: Manufacture if nagbetic powder for magnetic recording medium
Inventor: IDO TADASHI
IPC: C01G49/00
Filed: 1980-09-22
Abstract: PURPOSE: To manufacture magnetic powder for a magnetic recording medium with high recording density by removing a glassy substance contained in a hexagonal system ferrite composition with low coercive force contg. other atoms substituted for part of the constituent atoms and by disintegrating aggregated ferrite by ultrasonic  vibration.  
     CONSTITUTION: In order to provide coercive force iHc required by magnetic powder for a magnetic recording medium to magnetoplumbite type Ba ferrite, Co 2+ -Ti 4+ ions are substituted for part of Fe 3+  ions in the Ba ferrite. A glass forming substance is added to the resulting composition and mixed well. The mixture is melted by heating and cooled very rapidly by dropping onto twin rolls rotating at high speed to form an amorphous body. This body is kept at 700°C for 4hr to deposit hexagonal system ferrite by crystallization. The ferrite is washed with phosphoric acid, acetic acid or the like to remove the glassy component, and it is washed. Ultrasonic vibration is then applied to separate the secondarily aggregated ferrite particles into particles each having 0.01W0.3μm crystal particle size.

Abstract: PURPOSE: To decrease the overhead occuring at the level switching time by installing the main memory means possessing the interruption shunt regions of the prescribed number plus the plural interrruption level information storing means in a smaller number then that of the shunt regions.  
     CONSTITUTION: At the initial state, the initial value of interruption level register set selection register 4 is decoded by decoder 5 and then selected as the register set using 1st interruption level register 2 with the program of level l 0  under running. When the request of interruption level l 1  is given at time t 0 , the higher rank than level l 0  is detected at priority interruption decision circuit 12 to accept the interruption. Regsister 4 selects unused register set 3, and the information in read from interruption shunt region 9 of main memory 7 for the program running at level l 1  to be stored within set 3. When the unused register set is not available, the interruption level information stored in the oldest time is stored in the shunt region of memory 7. And then the interruption level information is stored in the register set.

Abstract: PURPOSE:To relax danger of an erroneous input caused by a hand touch, etc., by changing a shape of a spacer held between resistance film sheets to a shape of an acute angle, so that when pressure is applied widely to the side surface of a hand, etc., the spacer extends laterally. CONSTITUTION:This tablet is constituted of a resistance film sheet 1 of the upper side, a resistance film sheet 2 on a glass substrate 4, and a spacer 6 of an octahedron. One apex of the octahedron is stuck on the resistance film sheet 1, and the apex faced to this apex is stuck on the resistance film sheet 2. Also, each side of a quadrangle being a cross section in the vertical plane direction to the resistance film sheets 1, 2 of the spacer 6 makes an acute angle with the resistance film sheet. Accordingly, when small force of pressure per a unit area is applied to the resistance film sheet 1 extending over a wide range by the side surface of a hand, etc., the spacer 6 is deformed so as to extend laterally and the resistance film sheet 1 is also deformed in accordance tish this deformation of the spacer 6. As a result, the resistance film sheets 1 and 2 do not come into contact with each other by small force.
