Filed: 1991-08-30
Abstract: PURPOSE:To prevent a large input/output load from being simultaneously im pressed to an auxiliary storage device in the case of swapping-out the page of a job on a main storage device to the auxiliary storage device at a virtual memory system. CONSTITUTION:In the case of swapping-out a job 10 on a main storage device 1, first of all, a moving means 31 moves a page group 11 having the fixed number of pages onto an auxiliary storage device 2. Afterwards, a judging means 32 judges whether the pages to be moved are remained or not. When it is judged that those pages are remained, a waiting means 33 executes a waiting processing for fixed time and afterwards, a page group 12 having the fixed number of pages is moved again by the moving means 31. Then, the processing similar to the above-mentioned processing is executed until the judging means 32 judges that no page to be moved is left.

Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a high reliable light amplifier preventing a connector end surface from being damaged owing to heat caused by an excess light output by using a fiber expanding a mode field size for the output connector end surface of the high output light amplifier. SOLUTION: A connector 5 is provided on a tip of an outputting optical fiber 4 leading out an optical signal amplified and outputted by the light amplifier 3, and the inserted core of the tip part of the optical fiber 4 is exposed for optically coupling to an external lead-out path. Then, the connector 5 is formed so that the mode field size of the core is expanded in a reversely tapered shape on the end surface. When the mode field size on the output fiber end surface is made a structure expanded in such a manner, spatial optical power density on the output fiber end surface is reduced by the much that an area is expanded. Thus, even when dirt exists on this part, heat absorption is reduced. That is, the caused heat is dispersed spatially, and a temp. rise is suppressed.

Title: Disc storage device
Inventor: TSUKADA MASAHARU
IPC: G11B20/10
Filed: 1988-09-30
Abstract: PURPOSE:To prevent data from being recorded in an unrelated sector when a recording mode is erroneously set at the time of execution of a command by inhibiting real-time erasing or recording operations while the command is executed. CONSTITUTION:When command transfer is completed, a CMD-TRD signal is set and it is informed to a CPU 11 that a command is transferred. The CPU 11 reads the command data latched by a command input circuit 13 and, when the command is, for example, a seeking operation command, instructs a control block 12 to move a head. If a recording mode is abruptly generated while seeking operations are executed, AND gate circuits 14 and 15 are closed and recording data CMW-DATA or recording clocks W-CLK are not sent to a MODEM 16, because they are not outputted from the gates 14 and 15. Thus no recording data are outputted. Therefore, even when the recording mode is erroneously set while the head crosses tracks, no data are erroneously written in an unrelated sector and destruction of previously recorded data can be prevented.

Title: Magnetic powder for high density magnetic recording and magnetic recording medium employing same
Inventor: KUBO OSAMU
IPC: C01G49/00
Filed: 1988-09-30
Abstract: PURPOSE:To suitably enlarge an aspect ratio and to remarkably decrease the temperature dependency of a coercive force, by substituting a predetermined amount of Zr or Hf, and other elements for controlling the valency number, for a part of Fe as a constitutive element. CONSTITUTION:At least one kind of elements which are selected from Zr and Hf which have the number of atoms of 0.05-0.5per chemical formula, and at least one kinds of elements which are selected from the elements other than Zr and Hf, are substituted for Fe atoms contained in a substitute hexagonal system ferrite which has an average particle size of 0.01-0.2mum and a coercive force of 200-2000Oe. On the other hand, for the magnetic recording medium employing the magnetic powder described above, the magnetic powder is coated on the surface of a supporting body. When the average particle size of the uniaxial anisotropy of hexagonal system ferrite crystal is less than 0.02mum, both the magnetization and coercive force are reduced, and therefore the play back output of the magnetic recording medium is lowered, while when the average particle size thereof is above 0.2mum, the coercive force is reduced and the noise in playback is remarkably increased during high density recording.
