Title: Signal level adjusting circuit
Inventor: MATSUMOTO SATORU
IPC: H03G3/00
Filed: 1980-11-20
Abstract: PURPOSE:To enable accurate level adjustment, by making level adjustment through the conversion of an input signal to a low frequency signal having the same peak value as the maximum peak value. CONSTITUTION:When a changeover switch is changed over to 2a side, a signal applied to an input terminal 1 appears at an output terminal 5 through a level adjuster 3 and an amplifier 4 and is displayed on a level display device 10 and a DC voltage corresponding to the maximum peak value is stored in a peak value storage circuit 8. In adjusting the level adjuster 3, a voltage with the same level as the level stored in the circuit 8 is stored in a peak vaue storage circuit, the gain is controlled by applying this voltage to a variable gain amplifying circuit 17 and the peak value of a low frequency signal from a low frequency oscillating circuit 18 is regulated to the same value as the maximum peak value of the input signal. The switch 2 is then changed over to 2b side, a low frequency signal is applied and adjustment is made so that the level display is regulated to the objective level.

IPC: C21C1/04
Filed: 1987-07-02
Abstract: PURPOSE:To efficiently prevent slag from forming in pretreatment of molten pig iron by separately introducing mixed silica remover prepared with slag forming inhibitors large and small in grain size in a first half and latter half of a pretreatment to molten pig iron flow tapped from a blast furnace. CONSTITUTION:Previously, silica remover (comprising (a) and (b)) in which slag forming inhibitor large and small in grain size is arranged is prepared separately. Silica remover is continuously introduced with carrier gas into molten pig iron flow tapped from the blast furnace. In this case, said silica remover (a) is introduced in the first half of said pretreatment of molten pig iron and the silica remover (b) is introduced in the latter half of said pretreatment of molten pig iron. Accordingly, slag forming is controlled efficiently in the latter half term when the slag forming is specially large. As a result, Fe component in the slag is reduced to improve the yield of pig iron.

Filed: 1982-09-21
Abstract: PURPOSE:To prepare the titled compound in high purity, by lowering the temperature of the water to absorb the ammoxidation reaction gas thereby reducing the amount of the water and separating the absorption liquid into an oily layer and an aqueous layer, and feeding the layers to the different positions of the recovery column. CONSTITUTION:The ammoxidation reaction gas composed mainly of methacrylonitrile (abbreviated as MAN) is made to contact with the absorption water supplied through the line 3 to the bottom of the absorption column 1, and the absorption liquid is distilled in the recovery column 5 with the solvent water introduced through the line 6 to recover the MAN.

The absorption liquid is separated into the oily layer and the aqueous layer, and the layers are separated from each other in the separation column 7. The oily layer is fed through the line 9 to the recovery column at a point lower than the point to feed the aqueous layer, and the aqueous layer is fed through the line 8. The load for the extractive distillation in the recovery column can be reduced, the amount of the solvent water can be decreased, and the purity of the recovered liquid can be improved by this process.

Title: Control method for quality of concrete
Inventor: KIKUCHI ISAO
IPC: B28B11/24
Filed: 1981-10-16
Abstract: PURPOSE:To decide the strength of concrete after setting in an early time and to control the quality of concrete by measuring the propagation speeds of ultrasonic waves on unset concrete with lapse of time. CONSTITUTION:A sample 6 of mixed concrete is packed in a form 5, and an ultrasonic wave transmitting part 3 and a receiving part 4 are mounted on both outer side surfaces thereof. The propagation time between both of them is displayed on a display plate 2 by a body 1 of a propagation speed measuring device. From said time, the time when only the form 5 is used is subtracted and the result is divided by the distance between the inside surfaces of the form 5, whereby the propagation speed in the sample 6 is calculated. Said speed is measured with lapse of time and the time when the propagation speed is min. is determined, from which the relations of water-to-cement ratios are plotted. Since the strength of concrete has a high correlation with water-to-cement ratios, the strength of the cement when set is estimated from the water-to- cement ratios. Therefore the strength of the concrete is decided in an early time and the quality is controlled.
