Title: Power source protective circuit
Inventor: NAKAMURA SATOSHI
IPC: H02H9/02
Filed: 1988-12-09
Abstract: PURPOSE:To reduce the size of a power source protective circuit by employing a resistor having positive resistance-temperature characteristic as a current limiting resistor to be inserted in series with a switching element which is conducted detection of abnormal source voltage thereby reducing power to be consumed through the resistor. CONSTITUTION:A resistor 6 does not conducts and the resistance thereof is selected to limit the current below the maximum conducting current of a thyristor 5 under sufficiently cooled state. Upon erroneous application of AC 200V voltage onto an AC input terminal 1, the thyristor 5 is conducted by the voltage divided through voltage dividing resistors 7a, 7b. After conduction of the thyristor 5, resistance of the resistor 6 increases through self-heating and a protective fuse 2 is blown off thus protecting a smoothing capacitor 8 from breakdown. Resistance of the resistor 6 increases through self-heating as the temperature rises and thereby scarce power is consumed before blow-off of the fuse 2. By such arrangement, the size of the source protective circuit can be reduced.

The reduced metals are recovered. An extremely high temp. is generated by the oxidation decarburization and the exothermic reaction by the oxidation of the Fe, Mn, Ni and others during this refining stage and the refractory materials in the converter are eroded and, therefore, carbonates, such as CaCO3 and MgCO3, are used as the slag making agent and the inside of the converter is cooled by the endothermic reaction effected by the pyrolysis thereof, by which the erosion of the refractories is prevented. Since there is no need for using scrap, etc., as the coolant of the superheat converter like heretofore, the hit rate of the heat sizes and the yield of the valuable metals are improved.

Title: Cache invalidation control system
Inventor: SAKURAI YASUTOMO
IPC: G06F9/52
Filed: 1991-11-01
Abstract: PURPOSE:To provide the cache control system of plural hierarchies which can execute semaphore control without reducing the throughput of the system. CONSTITUTION:In the case that another processor 5 writes in a main storage device 1, if block data corresponding to that address is held in the buffer memory 4b of a cache 4, an invalidation control part 4c invalidates this block data. After the block data of the cache 4 is invalidated, the cache 3 invalidates the block data similarly to the cache 4. Since the cache 3 is invalidated after the cache 4 is invalidated, the cache 3 never reads the old data before invalidation of the cache 4, and the semaphore bit of the main storage device 1 and the semaphore bit of the cache 3 never become non-coincident.
