Title: Method for modifying smelting reduction slag
Inventor: TADA MUTSUMI
IPC: C04B5/00
Filed: 1989-06-19
Abstract: PURPOSE:To easily carry out the modification of slag with the irreducible minimum of the amount of boron oxide used at a low cost by putting a boron- containing oxide into a furnace at a specific bath temp. in the course of smelting reduction refining in a method for preventing the powdering of slag generated attendant on the smelting reduction of iron ores, etc. CONSTITUTION:At the time of modifying slag by adding a boron-containing oxide preventing the powdering of slag in a cooling stage to molten slag composed principally of dicalcium silicate generated attendant upon the smelting reduction of iron ores and chromium ores in an iron bath-type refining furnace, the boron-containing oxide is put into the furnace at a bath temp. where the boron oxide is not reduced to boron in the course of smelting reduction refining. It is preferable to regulate the above bath temp. to <=1620 deg.C. further, it is preferable to put the boron-containing oxide into the above furnace so that the concentration of B2O3 in the slag is regulated to 0.10-0.40wt.%. As the boron-containing oxide, borax, Kernite, colemanite, ulexite, etc., are suitably used.

Title: Power source voltage detection circuit
Inventor: SAKAGUCHI JIRO
IPC: G01R19/165
Filed: 1989-06-19
Abstract: PURPOSE:To enable a lowering of power-consumption and a reduction in an occupation area of a circuit itself by setting a capacitive voltage-division means using a capacitor connected in series thereto in a circuit for detecting a power source voltage in place of a voltage division resistor. CONSTITUTION:A capacitive voltage-division means 3 is connected to a power source line to divide a power source voltage Vdd and a first capacitor C1 and a second capacitor C2 are connected in series thereto. Then, a MOS type transistor 4 which is turned ON or OFF by a clock signal phi is connected between a series connection thereof and the voltage Vdd and an inverter 5 is connected to one end of the capacitor C2 to output a signal which is an inverted signal of the clock signal phi. Charging and discharging of the capacitors C1 and C2 are repeated alternately by the half cycle of the clock signal phi with a transistor 4 and the inverter 5. The divided-voltage output is processed with a voltage comparator circuit comprising a comparator 1A and a latch 2A to be sent to a means for reporting a drop in power source voltage. In addition, by setting electrostatic capacitance values of the capacitors C1 and C2 smaller, lower power-consumption is achieved.

Abstract: PURPOSE: To converge an X-ray to a required area to make a constant X-ray diffraction from a minute area possible to be carried out by combining pieces having a part having a designed form and having the other designed form together to form a parabolic surface or toroidal curved surface. CONSTITUTION: A polymer film selected from among aromatic polyimide, aromatic polyamide, and polyoxadiazole is thermally treated at 400-2000 deg.C to provide a graphite crystal 2. The curved graphite crystal 2 in which a parabolic, spherical, non-spherical or toroidal curved surface having at least one or more preliminarily designed curved form is worked as a part of the structure, is formed. This curved graphite crystal is mounted on an X-ray generating device for forming an emission type X-ray to converge an X-ray 4 to a required area. Particularly, the graphite crystal assembled and worked into the toroidal form converges the X-ray 4 to the required area without remarkably reducing the strength like a pinhole, and makes, a constant X-ray diffraction from a minute area passible to be carried out.

Abstract: PURPOSE:To achieve a high reliability by determining a static value depending on current variation in the control process for controlling a magnetic field to be applied to a magnetic fluid with a coil supply current to keep the difference constant in the level between the atmosphere side and the static pressure side thereof. CONSTITUTION:As the liquid level of a magnetic fluid on the atmospheric pressure side goes up with a rise in the static pressure, light to a light receiving element 4b from an electrooptic source 4a is intercepted with the magnetic fluid and a resulting detection signal is applied to a computer 6 from a control means 5, which performs a computation according to a prepared program to provide a feed back signal to the control means 5. As a result, the current value for a coil rises by a control signal and the coil behaves as if the specific gravity of the magnetic fluid changed with a magnetic motional resistance to lower the liquid level of the magnetic fluid on the atmosphere side.

Abstract: PURPOSE:To execute plural user programs on respective banks in parallel by switching stacks so that the existent user programs can be run on optional banks without being corrected. CONSTITUTION:When a user program stored in a user 3 area 500 is being executed, the value of a bank register 21 indicates the bank number of the area 500. Then if an interruption is initiated, control is passed to the interruption control program in an interruption control area 110 and switching from a stack area 510 to a system stack area 125 in a no-bank area is performed before a bank is switched to a user 2 area 400. Then, the bank number of a bank where a processing program for the generated interruption is arranged is set in the register 21 to switch the bank, and a corresponding interruption processing program is called to perform specific interruption processing. Consequently, the special processing regarding stack switching is performed by a system program and plural user programs are executed on respective banks in parallel.

Filed: 1987-06-22
Abstract: PURPOSE:To eliminate marks on the surface of a sheet and improve surface smoothness by a structure wherein a plurality of controlling blocks, each of which can project inwards with an extruding means, are provided on at least one of opposing walls consisting of an influx part, through which body passes, in a die. CONSTITUTION:The influx part 9 of body is formed between opposing walls 7a and 7b of a die. A plurality of blocks 10 are arranged on one wall 7b forming the influx part so as to be projected inward the influx part 9 through the pivoting of bolts 11 in order to change the resistance against the body when the body passes through the influx part. By controlling the projecting amounts of the blocks 10, the distribution of the resistance against the body is set to be larger at the middle part and gradually become smaller toward both ends of the influx part as indicated by the curve 13. As a result, a uniform sheet can be obtained. In this case, since the direct contact of the flow controlling block with the body mars the smoothness of the surface of the sheet due to the difference in level between the blocks, plastic or elastic body such as rubber or the like is preferably interposed between the blocks and the body.

Filed: 1993-06-28
Abstract: PURPOSE: To recover a clean air by removing a cyclic alkylene carbonate by taking out an air containing cyclicaclkylene carbonate from process and passing it through an aqueous alkaline liquid in a gas scrubber. CONSTITUTION: Even through a cyclic alkylene carbonate, a propylene carbonate as an example, used as either or both of the developer or the stripper, has a low vapor pressure and a high boiling point, a vapor containing a propylene carbonate arises during a process of photolithography. By transferring an air containing the propylene carbonate to a gas scrubber 21 and bringing it into contact with an aqueous alkaline liquid, the propylene carbonate is removed by washing, and produce a clean air 15 and a solution 17 containing the propylene carbonate. The solution 17 may be sent to a circulation 18 or sent to the next process 18. Thus an air not containing substantially any propylene carbonate is recovered from the process.
