IPC: C21C5/40
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently recovering dust having a high canon. from zinc oxide-contg. dust, such as iron making dust. SOLUTION: The oxide-contg. dust is agglomerated and is charged into a melting furnace in which molten iron is housed. Iron oxide in the dust is reduced in the molten iron and is recovered into the molten iron and the zinc oxide in the dust is reduced to zinc. The evaporated zinc is recovered as zinc oxide, by which zinc in the dust is recovered. At this time, a carbon material for reduction is mixed with the dust and the agglomerated dust is formed. The dust is charged into the melting furnace and the zinc oxide is thus recovered from the oxide-contg. dust. In the recovering method, the ratio of the carbon material for reduction to the dust is preferably set at 1.5 to 10 times the stoichiometrical ratio necessary for the reduction of the iron oxide and the zinc oxide.  A hydraulic additive is preferably added to the dust in addition to the carbon material in the agglomeration process of the oxide-contg. dust.

Filed: 1992-04-01
Abstract: PURPOSE:To make the I/O cell width wider than the pad pitch, regarding the arrangement method of I/O cells and pads of a master slice integrated circuit. CONSTITUTION:A pad 52 for power supply is arranged between two pads 51 for signal, and an I/O cell region 4 adjacent to the pads 52 for power supply are equally divided.

Abstract: PROBLEM TO BE SOLVED: To make it possible to minimize an adverse effect on environment, by minimizing the amount of fire extinguishing gas and the amount of gas exhausted to open air after extinguishment. SOLUTION: When a fire has occurred in a section 1, it is detected by a sensor 31, and a start signal is generated by a sensing signal of the sensor 31.

After the file is extinguished, a recovery signal is generated by a control board 35 manually, the recovery signal discharges fire extinguishing gas in the space 1a to open air. Furthermore, a gas compressor 19 operates in response to the recovery signal and recovers the fire extinguishing gas in the incombustible bag 18 to the vessel 12.

IPC: H01L21/027
Filed: 1978-06-30
Abstract: PURPOSE:To enable electronic beam to be exposed with high accuracy while tolerating minor error of driving system of DA converter, etc., by quantizing deviation magnetic field so that electronic beam spot radiation interval can be maintained at an appropriate value. CONSTITUTION:A magnetic field in a hollow super-conductive body takes a quantized value even at the time when an external impression magnetic field is continuously changed, and it possesses only a magnetic field which is an integer-fold single magnetic field. When thus quantized magnetic field is used as a deviation magnetic field for electronic beam, it takes a value of absolute accuracy even at the time when the external impression magnetic field contains a minor error, and therefore, it is possible to achieve spot exposure at an exact interval.

Abstract: PROBLEM TO BE SOLVED: To improve an accuracy for measuring a distance to an object to be measured, by overlapping a detection signal and a reference signal thereby to let the signals interfere with each other based on the homodyne technique utilizing a phase shift method, and detecting a phase difference. SOLUTION: A signal generation circuit 20 processes a basic signal in three kinds of phase modulation in a time-sharing manner thereby to generate a reference signal, with generating a driving signal of the same frequency as that of the reference signal. A light source 30 generates a signal light based on the driving signal from the circuit 20 and projects the light to an object to be measured 10. A photodetector 40 generates a detection signal based on the entering signal light after scattered and reflected at the object 10. A homodyne process circuit 50, 60 overlaps the detection signal with the reference signal from the circuit 20 thereby to obtain an interference signal.  A phase detection circuit 70 compares peaks of the interference signals correspondingly to switching of three kinds of phases of the reference signal, and highly accurately detects a phase difference between when the signal light is emitted and when the signal light is detected. An accuracy for measuring a distance to the object 10 is thus improved.
