Abstract: 1440285 Error correction INTERNATIONAL BUSINESS MACHINES CORP 24 April 1974 [4 June 1973] 18002/74 Heading G4A Data is stored on a plurality of independently accessible storage units, e.g. magnetic tape cartridges, and check bits, each of which is a function of a corresponding bit from each data storage unit, are stored on a check unit which may be used, in the event of a catastrophic loss of data on one of the data storage units and detected by an error checking facility associated with that unit, to restore the data on that unit. Extension of the system to include more than one check unit, each of which stores the check bits for one position of a Hamming code, is also mentioned. In normal operation, one of the data storage units is selected and data thereon is updated by read before write heads 15, 21. The difference e jk  between each old bit and the corresponding new bit is EXORed with the corresponding old parity bit p k  from the check unit to update the parity bits. The parity bits are initially recorded by successively (or simultaneously) reading the data storage units to record the modulo 2 sums of the corresponding bits, and data restoration is similar reading from the good data storage units and the check unit.

Title: Slag stopper device for furnace opening lid
Inventor: KAKITSUBO YUKIO
IPC: C21C1/06
Filed: 1987-03-09
Abstract: PURPOSE:To stably prevent the flowing out of slag at all times, by penetrating a main stopper body into the furnace opening of a torpedo ladle car, and providing a mechanism for blocking the slag with the stopper body when the torpedo ladle car is tilted. CONSTITUTION:A detaining hook 7 on a frame 2 side is dropped into a pin bracket C on the torpedo ladle car A side from the upper part and engaged with the bracket, and the slag stopper 1 is set. At this time the main stopper body 3 penetrates into a furnace opening B to cover the central part of the furnace opening, and an opening 17 is formed between the body 3 and a furnace opening wall D. When the car A is tilted, the detained hook 7 slides on the pin bracket C, hence an antislipping claw 9 on one side is detained by the pin of the pin bracket C, and the stopper 1 is not detached. Consequently, although molten iron flows out from the opening 17, slag is blocked by the main stopper body 3. When the car S is further tilted, the main stopper body 3 is moved to the titled side along a V-shaped guide hole 11 on the frame 2 side, hence the opening 17 is reduced, and the flowing out of slag is prevented.

Abstract: PURPOSE:To find overheating and prevent burning by using a sintered alloy impregnated with perfume at a heat generating part inside a motor. CONSTITUTION:A stator 2 and a rotor 3 are built inside a case 1. A grinding wheel is provided to rotate as a tool 5 on one side of the case 1 through a speed reducer 4, and an intake port 6 and a fan 7 are provided on the other side. Sintered alloy 10, which is impregnated with perfume with the insulated outside, is attached closely to the winding 9 of the stator 2. If overload occurs in the tool 5 during rotation, both the stator 2 and the rotor 3 overheat due to excessive currents flow, and the sintered alloy 10 is heated, and the impregnated perfume volatilizes. Since the smell of the perfume diffuses from the exhaust port 8 to the outside of the case 1 by the fan 7, the worker can confirm it easily and find the abnormal heat generation in the inside.

Abstract: PROBLEM TO BE SOLVED: To obtain a flexible conductive wire where the inexpensive conductive wire small in diameter is materialized, no tension strength is degraded at all even if it is made small in diameter, and it is excellent in straightness while the occurrence of small bending is prevented. SOLUTION: A primary coat layer 2 is formed as a core material over the outer circumference of an entire synthetic quartz glass core 1. The primary coat layer may be made of for example, nickel. A conductive layer 3 is disposed over the outer circumference of the primary coat layer 2. This conductive layer 3 is made out of a copper alloy, OFC and brass may be used as a conductive layer other than the aforesaid materials. The rupture strength of a quarts glass wire manufactured so as to be sheathed with a copper alloy 10 is roughly to the extent of 33.5 to 37.6N. As compared with the strength of a current discharge wire made of a copper alloy of 31.4N (0.2mm in outer diameter), the strength can be thereby remarkably improved, and furthermore, its outer diameter can be made smaller roughly from 0.2mm down to 0.13mm.
