Title: Control procedure of steel making process using mass spectormeter
Inventor: HOSHI NORIO
IPC: C21C5/30
Filed: 1977-09-10
Abstract: PURPOSE: A mass spectrometer separates and measures partial pressures of Co and Co 2  in waste gas and compares measured values with those of standard gases. Based on this comparison, the end point C of smelting furnace is controlled so as to reach the end point with improved accuracy.  
     CONSTITUTION: For example, stainless steel is smelted by blowing oxgen with aimed end point C:0.30%, using 42 charges. In No.1 to 20 charges, Ar standard gas passes through conduit 7, flow meter 13 and into conduit 6. In the remaining No.21 to 42 charges, Ar is conducted via conduit 7 and flowmeter 13 into waste gas 11 consisting of reacted gas 9 and incoming air 10 and throughly mixed with them. A pump 15 leads the mixed gas 11 into a mass spectrometer 16, which continuously measures the gas, calculates decarburization quantity delta C%, using predetermined program, to compare it with decarburization quantity delta Co of actual operation. This gives predictive molten steel weight W and correction factor b at time t, which provides a basis for controlling end point C of smelting furnace. This procedure improves end point predication and enables non-convertion furnace operation.

IPC: G01N21/17
Filed: 1979-08-28
Abstract: PURPOSE:To easily and quickly obtain an appropriate estimated value of paper-weight by scanning the surface of measured paper with a light beam to detect the transmittance of the paper and  estimating the diversity of measured weights from the product of the standard deviation value of  the natural logarithm of each instantaneous value of the transmittance and a weighing conversion  coefficient determined by an appropriate method. CONSTITUTION:The surface of a sample 3 is scanned by a beam emitted from a light source 1  and reflected by a vibrating mirror 4. A transmittance signal Ti is supplied to an optical density nonuniformity calculation and indication unit D by a light reception means 5 and a photoelectric  conversion circuit 6. The signal Ti is processed through a logarithm conversion circuit 12, an AC discrimination circuit 14, a ratio calculation circuit 15 and a DC discrimination circuit to determine the ratio Fc of the standard deviation of the natural logarithm of the signal Ti to the  natural logarithm of the mean value T of the signal Ti. A signal lnT from a DC conversion circuit 13 is applied to a weighing conversion number signal setting means E to calculate a weighing  conversion number (p) in accordance with a prescribed experimental formula relating to measured weight W, the mean value T and the number (p). A measured weight disparity evaluated  value is determined from a product pXFc by a calculation circuit 21 and applied to a display  means 22. The appropriate estimated value is thereby easily and quickly obtained.

Title: Damper device
Inventor: KURABAYASHI HIROSHI
IPC: F16F7/12
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To improve the damping property and durability of a damper device by providing a coil spring made of a metallic material having a low yield point, a pair of coil spring holders fixed to both ends of the coil spring, one of which is connected to a structure and the other of which is connected to a foundation, and a spline shaft extending through the coil spring. SOLUTION: When a building is vibrated by an earthquake or strong wind, the displacement by this vibration is transmitted to one coil spring holder 2 through a bracket 9, a joint plate 10, a shaft case 7, and a stopper plate 5. It is also transmitted to the other coil spring holder 3 through a ball bearing 24, a bracket 14, a joint plate 15, and a stopper plate 12. Consequently, since both the coil spring holders 2, 3 are mutually approached and separated to extend and contract a coil spring 1, the spline shaft 20 is slid in the axial direction to a bearing housing 17 and the shaft case 7. The coil spring 1 finally plastically deforms and absorbs the vibration energy to moderate the vibration of the structure.

IPC: H04B3/23
Filed: 1988-05-07
Abstract: PURPOSE:To reduce the arithmetic quantity such as stable processing to a narrow band signal or a rounding off processing by splitting a filter coefficient of a simulated echo generating section into plural groups and applying sequentially the addition processing of an addition constant and the multiplication processing of a multiplication constant set by a constant setting means for each group. CONSTITUTION:A DC component is superimposed to an input signal of a simulated echo generating section 1 by a superimposing means 2 to generate a DC component proportional to the quantity of an error of a filter coefficient caused by the truncating processing at coefficient correction. The addition constant and the multiplication constant are set corresponding to the quantity of DC component by a constant setting means 4. Moreover, the probability of the round-off processing in the coefficient correction is 1/2 and a half of the maximum truncating quantity has only to be added to all filter coefficients per one period in average. Then the addition processing of the addition constant and the multiplication processing of the multiplication constant are applied for each group. Thus, the arithmetic quantity by the round-off processing executed to all the filter coefficients is reduced for each period.
