Title: Alloying method of molten metal plating
Inventor: MIZUTA SHIGEO
IPC: C23C2/28
Filed: 1985-04-27
Abstract: PURPOSE:To alloy a plating metal and steel plate uniformly and to improve the thermal efficiency of an alloying furnace by passing the plated steel plate after metal hot dipping through the alloying furnace in which a waste gas is used as a combustion supporting gas for fuel combustion thereby heating the steel plate. CONSTITUTION:A steel strip 1 is conducted to a metal hot dipping bath 2 where the strip is plated. The plated strip is then controlled of the deposition of the plating metal by the gas injected from gas injection nozzles 3 and thereafter the strip is passed through the alloying furnace 4 where the strip is heated. The alloying treatment of the plating metal and the strip 1 is thus executed. The waste gas from the alloying furnace recovered through a hood 5 is supplied as the combustion supporting gas for fuel combustion together with gaseous fuel to the burners 8 in the above-mentioned alloying furnace 4. The decreased combustion rate of the gaseous fuel, the decreased max. temp. of the flame and the increased volume of the waste combustion gas are thereby caused, by which the temp. distribution in the furnace is made uniform and the uniform alloying treatment is made possible. The thermal efficiency of the furnace 4 is improved by utilizing the sensible heat of the waste gas.

Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling an incinerator capable of suppressing emission of a hazardous substance; to the atmosphere by supplying an amount of air corresponding to the property (quality of waste) of waste. SOLUTION: Property of waste are obtained on the basis of the specific gravity and water content of the waste and the amount of air required in an incinerator 1 is calculated according to the property of the waste, and the standard amount and limit range of secondary combustion air is calculated and the amount of the secondary air supplied to the incinerator 1 through a nozzle 47B is changed within the scope of the limit range, and the total amount of the secondary combustion air supplied to the incinerator 1 through the nozzle 47B is changed so as to be equal with the standard amount of the secondary combustion air.  By employing this method, control is stabilized by supplying an amount of air corresponding with the quality of the waste, and further incomplete combustion is prevented and emission of an hazardous substance to the atmosphere is suppressed by producing turbulence by variation of the secondary combustion air and stirring combustion gas.

Title: Magneto-resistance effect head
Inventor: HAYAMA NOBUYUKI
IPC: G11B5/39
Filed: 1984-05-07
Abstract: PURPOSE:To secure an even output of reproduction by decreasing the space between both electrodes connected to a magneto-resistance effect MR element at the side close to a magnetic recording medium and therefore defining an area contributing to the smallest change of resistance as a reproduction output. CONSTITUTION:The space between electrodes 3 and 4 connected to an MR element 1 is decreased at an area close to a magnetic recording medium 2. Therefore a sense current flowing to the element 1 via electrodes 3 and 4 becomes uneven in the width direction of the element 1 and is concentrated at the area close to the medium 2. The change of resistance of said area contributes most to the reproduction output. Thus it is possible to secure easily an even reproduction output to a wide range of recording density without demagnetizing the medium 2. Furhtermore a bias current is obtained in proportion to the sense current in order to secure a bias state where the area close to the medium 2 has the maximum sensitivity. In this way, the reduction of the reproduction output is compensated in a high recording density mode and the satisfactory recording density characteristics are obtained.

Title: Quasi optimization method for scheduling problem
Inventor: SUZUKI TAKAHIKO
IPC: G06F19/00
Filed: 1994-03-24
Abstract: PURPOSE:To decide a production process schedule in a comparatively short time and to find a solution satisfied by a planner i.e., a quasi optimization solution by evading the nonexistence of the solution by performing self adjustment by varying the constraint condition of the production process schedule. CONSTITUTION:For example, in a manufacturing system of cement, a cement clinker from a calcining system 1 is stored transiently in an intermediate silo 2, and after it is milled in a milling system 3 with gypsum, cement as a final product is sent out from a product silo 4 to shipping equipment 5. In such a case, a state in which a targeted soultion can be obtained by clearing the constraint condition is generated when unmatching occurs between input data and the constraint condition. Therefore, a penalty constant and a penalty variable to relax the limiting value of a constraint equation are added. In this way, it is possible to set a state to which constraint condition importance should be given depending on the value of the penalty constant, and simultaneously, the solution of a linear programming problem is outputted by performing the self adjustment by supplying the excess share of a constraint value as the penalty variable.

Title: Flowmeter
Inventor: HANAI HIROKORE
IPC: G01F1/66
Filed: 1989-04-12
Abstract: PURPOSE:To measure a flow rate over a wide range while following up variation in flow rate continuously by providing two measurement blocks made of supermagnetostrictive materials in a flow passage tube at a constant-distance interval. CONSTITUTION:Pulses which are generated by a pulse generator 13 are amplified by an amplifier 14 and applied as a pulse current to a coil C1. Consequently, a measurement block B1 vibrates pulsating to send sound wave pulses into liquid to be measured which flows in the flow passage tube 10. A block B2, on the other hand, receives the sound wave pulses and is strained mechanically to vary magnetic flux. A coil C2 generates output pulses by the variation of the magnetic flux. Then the flow rate is calculated continuously and repeatedly from the time difference between the pulse input from the pulse generator 13 to an arithmetic circuit 16 and the pulse input from the coil C2. Consequently, the flow rate can be measured continuously over a wide range while following up variation in the flow rate.

Therefore, the power loss of the bridge 1 can be reduced by controlling the bridge 1 near 0V.
