Title: Data invalidating device for cache memory
Inventor: TOMIZAWA KATAYUKI
IPC: G06F12/08
Filed: 1993-11-19
Abstract: PURPOSE:To prevent redundant invalidating processing from being performed and processing speed from being decreased. CONSTITUTION:When data write from an input/output device 13 to a main memory device 102 is performed, and address on the present bus is compared with the one of a latch L1 by a comparator 105 at an invalidation control part 61, and the invalidation of a corresponding block is performed only when noncoincidence is obtained between them. Simultaneously, the address on the present bus is compared with the address of the latch by the comparator 105 even when data for the main memory device 102 is read out from a CPU 101. The latch L1 is cleared only when coincidence is obtained between them. In this way, when the input/output device 103 writes the data of the same block address successively, the block address written by the input/output device 103 remains without being cleared even when the CPU 101 reads out the data of another block address and transfers it to cache memory 107 in the middle way of write.

Abstract: PURPOSE:To prevent stress of a circuit or a malfunction of a safety circuit or the like by detecting the fact when a discharge lamp whose rated power is unfitted is connected. CONSTITUTION:When an electric power supply switch is turned on, a discharge lamp 49 is preheated.

Abstract: PURPOSE:To prevent the occurrence of a possibility that dust in a vacuum film forming chamber is moved to an exhaust device through an exhaust port to cause the malfunction and the failure of the exhaust device by installing a dust removal shutter that can freely be opened and dosed in an inlet of the exhaust port in the vacuum film forming chamber. CONSTITUTION:After a film forming chamber 1 is evacuated by a vacuum pump 7, a target 4 is irradiated with ions from an ion source 2 to stick sputter particles of the target 4 on a substrate 3, causing a film to be formed. After the film forming is finished, the ion source 2 and the vacuum pump 7 are stopped from operating and simultaneously a gate valve 6 is closed. Next, after an exhaust port 5 of the chamber 1 is closed by a shutter 9 by operating a knob 92, a leak device 8 is opened to let leak gas, such as dry gaseous nitrogen or dry air into the film forming chamber 1, causing the film forming chamber 1 to be at the same pressure as the atmospheric one, allowing the film formed substrate 3 to be taken out. In this case, a possibility that by the introduction of leak gas, such as dry gas, dust 10 in the film forming chamber 1 is blown up and enters a gate valve 6 and the vacuum pump 7 from the exhaust port 5 is prevented by the shutter 9, causing the fault of the gate valve 6 and the vacuum pump 7 due to dust entering to be prevented.

Title: Magnetic recording medium
Inventor: MINAMI KATSUTOSHI
IPC: G11B5/738
Filed: 1988-12-13
Abstract: PURPOSE:To improve the CSS durability of the magnetic recording medium and to prevent the damage of the medium and a magnetic head by interposing a layer consisting of Cr2O3 between a substrate consisting of a synthetic resin and a magnetic recording layer. CONSTITUTION:The layer consisting of the Cr2O3 is interposed between the substrate consisting of the synthetic resin and the magnetic recording layer of the magnetic recording medium formed with the synthetic resin on the substrate consisting of the synthetic resin. Namely, the layer consisting of the Cr2O3 which has higher in electrical conductivity and hardness than the synthetic resin used for the substrate is interposed between the substrate and the magnetic recording layer. The electrification of the substrate surface is suppressed in this way and, therefore, the pickup of dust, etc., on the substrate surface is obviated. The signal defects of the formed magnetic recording layer are drastically decreased and the damaging of the magnetic recording medium and the magnetic head is prevented. Further, the surface hardness of the magnetic recording medium increases and, therefore, the wear resistance of the surface is improved and the CSS durability is improved.
