Title: Blast furnace top even charging device
Inventor: SATOU MAMORU
IPC: C21B7/18
Filed: 1979-05-19
Abstract: PURPOSE:To eliminate the unevenness of the raw material charging by a turning chute by providing a control plate to the wall in the stationary hopper. CONSTITUTION:Raw materials are charged by a belt conveyor 1 into a stationary hopper 4 through a turning chute 3 by way of a stationary chute 2. At this time, there is a tendency that the rate of effluence becomes higher at the portions closer to 3' than closer to 3'' owing to the effect of the directions of the flow of the raw materials and the raw materials having been charged into the stationary hopper 4 are not always of an even level in the circumferential direction. Thereupon, a volume-control plate 11 which is pivotally fitted turnably at the top end is provided on the wall surface A on the side 3' where the raw materials are charged at a larger amount, and the cavity 14 corresponding to the raw material charging level is formed by the rod 13 of a hydraulic cylidner 12. Thereby, the unevenness of the level in the circumferential direction of the raw materials is eliminated and the hanging and slip in the furnace are prevented.

Title: Humidity detector
Inventor: TSUCHIYA SHIGEKI
IPC: G01N27/12
Filed: 1980-05-10
Abstract: PURPOSE:To obtain a digital signal in proportion to a relative humidity, by a method wherein a differential signal, which differentiates a pulse from a pulse generator, is amplified in proportion to a resistance value of a humidity-sensitive element, and a time width pulse, which has higher than the given level of said signal, is measured. CONSTITUTION:A pulse signal, generated by means of a pulse generator 1, is differentiated by a condenser 2 and a resistor 3, and the differential signal is inputted to an inversion input terminal of an amplifier 6. A resistance system humidity-sensitive element 5, whose resistance value changes exponent-functionally, is connected to the amplifier 6 in the middle of a return ranging from an output side to the inversion input terminal. This adds a differential signal, having a waveform being symmetrical to a time axis, to the humidity-sensitive element 5, and exerts no polarization action. Additionally, a decay time T, which elapses during the decrease to the given level of the differential signal, changes in a straight line according to changes in a relative humidity. The decay time T opens a gate 9 for the duration of a time T, and a pulse E from a crystal oscillator 10 is measured by counting through the working of a counter circuit 11.

Abstract: PROBLEM TO BE SOLVED: To reflect a joint status to a joint process early by obtaining an opening size based on passage time of the joint of rolled materials obtained by hot finish rolling facility and a detection signal of a plate width position and measuring an opening shape of an end of the joint. SOLUTION: Steel pieces joined by a joining device 24 placed between an output of a rough roller 20 and an input of a finish roller 22 are successively rolled by the finish roller 22 to be a strip 18.
