Inventor: HASHIMOTO KATSUHIKO
IPC: B21B39/00
Filed: 1986-02-22
Abstract: PURPOSE:To realize the correct speed control of a carrier roller by correcting an advance rate estimation model equation by using the advance rate re- arithmetic operation vale amended by arithmetic operation from an observed advance rate and observed parameter value and by performing the speed control by using the estimation value adding the correction. CONSTITUTION:The advance rate is found by the advance rate estimation model equation by integrating the pulse number generated from the pulse generator 5 of a driving motor 4 while the tip of a rolled stock 1 is passed through the space between the tip position detecting devices 6, 7 at the rolling roll 2 outlet side, in the 1st stage. In the 2nd stage an advance rate re-arithmetic operation value is found with the re-arithmetical operation by using the observed value for the variable which is used for the arithmetic equation finding the advance rate. The speed of the rolled stock 1 at the roll 2 inlet side and outlet side is estimated by correcting the advance rate estimation model equation by the value obtd. at the 1st and 2nd stages, in the 3rd stage. A carrier table roller 3 is subjected to a speed control by setting to this estimation value. In this way the correct speed control of the carrier table roller can be performed.

Filed: 1987-02-19
Abstract: PURPOSE:To reduce N concn. in molten iron by charging ore containing element rising activity coefficient of N in the molten iron or element generating nitride by reacting with N, together with oxygen enrichment in blast in a blast furnace operation. CONSTITUTION:The oxygen enrichment in the blast is executed under the operation of fine powered coal blast in the blast furnace. Together with this, the ore containing one kind or more of elements, which increases the activity coefficient of N in the molten iron, such as Ni, B, or which generates the nitride by reacting with N in the molten iron, such as Ti, B, Nb, Ta, V, is charged by lump state from the furnace top in the blast furnace.

Abstract: PURPOSE:To provide a sensible heat storage device which is reduced in size and enables fetching of high temperature heat energy, by a method wherein high temperature liquid fed in a reduced pressure state from a pressure vessel in position above which a heat storage vessel is located and which is sealed with noncondensing gas and differently fed low temperature liquid are mixed together, and the mixture is utilized as liquid having a given temperature. CONSTITUTION:Water in a low temperature low pressure state is fed to a heat storage vessel 1 in a state, having a pressure higher than the steam pressure of water at a design heat storage temperature, with the air of a pressurizing pump 3. The water is heated by a heater 4 in a state that a pressure is held by means of noncondensing gas in a heat storage vessel 1 and a check valve in a water feed pipe 2, and temperature is increased to a value lower than the vaporizing temperature of water at a set pressure. Since pressure is too high to feed hot water in a pressure vessel as it is, a pressure is reduced by a regulating valve 6, hot water is mixed in a low pressure vessel 7 with cold water through water feed pipe 8, and a pressure is reduced to a value approximately equal to the pressure of ordinary supply water to feed hot water through a hot water feed pipe 9. The opening of the regulating valve 6 is regulated through proper combination of the flow rate and the temperature of hot water feed of the hot water feed pipe 9, the flow rate and the temperature of low pressure feed water, and a pressure and a temperature in the heat accumulator 1.

Abstract: PURPOSE: To better the response property of the power detector in the measurement of power by directly amplifying the output of the power detector or converting thereof into the DC voltage after converted into an AC signal depending on the level of the measured signal.  
     CONSTITUTION: It is determined whether the measured signal S is above specified level or not. When it exceeds the level, a switching gear 18 is driven to feed the output of the power detector 10 to the DC amplifier 11. The DC signal thus amplified is fed to a linearity compensator 12 to compensate for the linearity. The output signal thus obtained is indicated on the display 17 such as CRT for measuring the amplitude or such as digital meter for measuring the power. On the other hand, when the signal S is below the specified level, the switch gear is driven to feed the output of the power detector 10 to a DC/AC converter 13 with which it is converted into an interrupted AC signal by a low frequency signal. Thereafter, the output signal of the converter 13 is detected with a detector 15 in synchronization with the low frequency signal, converted into a DC voltage to be indicated on the display 17 to measuring the power.

IPC: G01D5/24
Filed: 1980-03-26
Abstract: PURPOSE:To substitute nonrectilinear conversion properties with rectilinear conversion properties with a simple constitution by compensating for the output characteristic with the help of a feedback circuit. CONSTITUTION:An output high-frequency signal from a charge & discharge-type oscillator OSC is applied to a sensor SS through the intermediary of an oscillation switch SW1 by means of FET. In addition, an output from OSC is supplied to a ring counter CT to control the SW1 with an output of a fixed period. Each capacity between a fixed electrode and a movable electrode of SS differentially changes according to a physical value and a high frequency output alternately generates from the movable electrode, being converted to a DC voltage by a detection part DT. This DC voltage is branched by means of a sampling switch SW2 and then is output to an output part OT. An output from OT is fed back to DT through a feedback circuit FB, a control part AC and a variable capacity element VC, giving a concave nonrectilinearity to input/output properties after DT. Thus the convex nonrectilinearity of SS is compensated for.
