Title: Diagnosing system of circuit block
Inventor: TAKAHASHI HIROSHI
IPC: G06F12/16
Filed: 1982-04-08
Abstract: PURPOSE:To realize a diagnosis by a common diagnosis data, even for a circuit containing ROMs different in contents, by accessing a diagnosing input data only to the diagnosing region of the ROM, then diagnosing the working of a circuit block. CONSTITUTION:For an ROM 11 of a circuit block 1, the address of a part of the ROM 11 functions as a region for a diagnosis data with other addresses used to user regions respectively. The contents of the region for diagnosis data can be used in common as long as a circuit part 12 is used in common. An input terminal 3 is equivalent to the address to the ROM 11. A diagnosing input data accesses only to the diagnosing region of the ROM 11 and diagnoses the working of the block 1. As a result, the diagnosis is possible with use of a common diagnosis data regardless of any big change of the user region of the ROM 11. Thus it is possible to diagnose a circuit block including an ROM storing various kinds of contents with a common diagnosis data.

IPC: C21C7/00
Filed: 1979-05-14
Abstract: PURPOSE: To refine the low carbon high chromium steel economically while the oxidation loss of Cr is reduced by a method wherein a preliminary decarburized amount by the oxygen lancing in the atmosheric pressure is reduced and a decarburized amount is increased by a vacuum oxygen lancing.  
     CONSTITUTION: In case of preparing the low carbon high chromium steel, as a stock material, steel scraps, high carbon Fe-Cr, high carbon Fe-Ni or the like are used and molten by an arc furnace. In this time, if a molten C amount is 0.80% or below, a vacuum oxygen lancing method (VOD) is directly applied to decarburize and refine to a low carbon range and, if 0.80W1.20% or more, the oxygen lancing is carried out in the atmospheric pressure to decarburize. In the C content of this degree, the oxidation of Cr is low even by the oxygen lancing decarburization under the atmospheric pressure. Particularly, after a high Cr steel containing C: 0.30W 1.20% is subjected to the oxygen lancing in an oxygen quantity 0.5Nm 3 /min., the vacuum natural decarburization is carried out at least for 10 or more min. to prepare a low carbon high chromium steel without oxidizing Cr.
