Inventor: IMORI HIROMITSU
IPC: G06F9/46
Filed: 2001-10-04
Abstract: PROBLEM TO BE SOLVED: To prevent unnecessary system failure and enhance reliability of the system. SOLUTION: Assuming that a unit 101 requests a unit 102 to execute a store instruction and requests a unit 103 to execute a rfid instruction for switching from an OS to a user program (UP), the unit 103 causes a register 106 to have an identification bit 114 of '1' (UP) and notifies a circuit 107 of the execution of the rfid instruction. The circuit 107 sets a flag 108 and sets a register 109 to '0'. The value of the register 109 is added by a +1 circuit 110, and compared with the value of a register 112 by an identity circuit 111. When the values are identical, the circuit 107 resets the flag 108 to '0'. A failure notice is given from the unit 102 to the unit 104 and the circuit 107, and thereby, when the flat 108 is '1', the circuit 107 sets a flag 113 to '1' as failure during surveillance. Otherwise, the flag 113 is set to '0'.  When the flag 113 is '1', the failure is handled as occurring in the OS. When the flag 113 is '0', the failure is handled as occurring in the UP.

Title: Iron-based metal soft magnetic dust core
Inventor: SATO NAMIO
IPC: B22F1/00
Filed: 2001-10-19
Abstract: PROBLEM TO BE SOLVED: To provide an iron-based metal soft magnetic dust core for electronic parts having high magnetic properties, namely, high permeability, high magnetization saturation, a small loss, a stable DC superimposed characteristic, etc., and to provide a method of manufacturing the dust core. SOLUTION: It is found out that primary particles containing strains exist in the crystals of individual particles, and that the magnetic properties of this dust core can be improved by producing sub-grains of 150-700 nm in width in the particles by selecting treating conditions for relieving the strains. Since the high-frequency characteristic of the dust core becomes worse and uncontrollable when the mean particle diameter of iron powder exceeds 220 μm in the used material, the appropriate mean particle diameter of the iron powder is <=220 μm. In addition, although the magnetic properties of the dust core can be improved to some extent even when sub-grains have spherical shapes, the properties can be improved more when the aspect ratios of the sub-grains are adjusted to >=3.
