Title: Error correcting method
Inventor: ICHII HIROSHI
IPC: G11B20/18
Filed: 1983-07-15
Abstract: PURPOSE:To correct an error by making the error correction with a hardware pointer and an error correction code when the number of errors in reproduction occurring in one block is smaller than a fixed number, or with the error correction code only when not. CONSTITUTION:If there is no error in a record No1 and an error is found when a record No2 is read, a signal ''1'' is outputted to a decoder output PCNT and a signal ''1'' outputted by a register circuit 21 is used by an error correcting circuit to correct the error. If an error occurs as well when a record No3 is read, an output signal is sent out to an error correcting logical circuit similarly. When the number of output signals exceeds some value, the 1st error correction via the hardware pointer is made ineffective and the 2nd error correcting method by the error correcting function that an ECC logical circuit itself is switched to. Consequently, errors occurring at random in plural records can be corrected within the range wherein they are correctable with individual ECCs of code words.

Title: Method for supplying heat source to steelmaking converter
Inventor: FUJII TETSUYA
IPC: C21C5/30
Filed: 1984-06-25
Abstract: PURPOSE:To improve the refining capacity with use of an inexpensive heat source while preventing an increase in S concn. by spouting the powder or the liquid of a substance contg. C and gaseous O2 from the upper part of a converter through a lance, and blowing the mixture onto the surface of a molten iron bath in the converter as a flame. CONSTITUTION:Pulverized coal 6 is entrained by gaseous N2 as a carrier and introduced into a lance 2 in the conventional carburization operation in a conventional top and bottom-blown converter 1, and gaseous oxygen is simultaneously introduced into the lance 2. Then the pulverized coal 6 and the gaseous O2 are spouted from the leading end of the lance 2 at high speed to form a jet, and both jets are mixed by collision at a position comparatively close to the leading end of the lance due to the structure of the lance. Accordingly, a high- temp. flame 4 is formed above the surface of a molten iron bath 3, and the flame 4 is struck upon the surface of the molten rion bath to transmit the heat of the flame 4 to the molten iron 3. Consequently, the amt. of solid materials such as scraps can be increased, and the reduction of iron ore, Mn ore, etc. can be advantageously carried out in the converter.

Title: Two component type diazo copying material
Inventor: SUGURO YOSHIHIRO
IPC: G03C1/61
Filed: 1984-06-25
Abstract: PURPOSE:To improve the shelf stability of an image and to inhibit the discoloration or fading as well as to make the image easy to see because of a bluish color tone and high contrast to the ground by incorporating zinc chloride and a benzimidazole deriv. into a diazo photosensitive layer. CONSTITUTION:A photosensitive layer contg. a diazonium salt, a coupler, zinc chloride and at least one kind of benzimidazole deriv. is formed. The benzimidazole deriv. and zinc chloride in the layer make the color tone of an image bluish and increase the contrast. Since the amount of thiourea to be added can be reduced, reduction in shelf stability and acceleration of discoloration or fading as harmful side effects of thiourea are not caused. A very small amount of the benzimidazole deriv. incorporated into the photosensitive layer produces a significant effect in the presence of zinc chloride. A copy easy to see and having superior shelf stability can be obtd.

Title: Oxide superconducting wire and its manufacture
Inventor: MAEDA HIROSHI
IPC: H01B13/00
Filed: 1990-05-21
Abstract: PURPOSE:To improve magnetic field dependence of critical current density of a superconductor and improve pinning force by having non-superconductors mixed in an oxide superconductor in the shape of fine lines or ribbons. CONSTITUTION:Y-Ba-Cu-O, Bi-(Pb)-Ca-Sr-Cu-O, Tl-Ca-Ba-Cu-O, etc. are applicable as oxide superconductors, while gold, silver, platinum, etc. which do not easily react with the oxide superconductor and can be easily deformed by processing can be used as a non-superconduction phase. Non-superconductors in the shape of fine lines or ribbons are mixed lengthwise in an oxide superconducting wire. Thus movement of fluxoid quantum line which has entered inside the superconductor can be suppressed, and pinning force can be improved better than a conventional spot-like pinning force.
