Title: Method for refining and recovering high purity zinc oxide from dust in steelmaking
Inventor: KANEKO YASUO
IPC: C22B19/34
Filed: 1990-10-09
Abstract: PURPOSE:To recover Zn by separation from other components by applying reducing roasting to the Zn-containing dust in steelmaking to form Zn into easily vaporizable crude zinc oxide, dissolving this crude zinc oxide in an aqueous solution of hydrochloric acid, reducing trivalent Fe in the solution to bivalent Fe, and allowing dissolved zinc to be adsorbed by ion-exchange fiber bodies. CONSTITUTION:Zn-containing dust in steelmaking is subjected to reducing roasting in a rotary kiln, etc., to vaporize Zn into crude ZnO, and this crude ZnO is passed through an aqueous solution of hydrochloric acid and allowed to dissolve as ZnCl2, and other insoluble impurities are separated by filtration. The resulting ZnCl-containing filtrate is passed through a column filled with iron pieces to undergo the reduction of trivalent Fe in the filtrate to bivalent Fe, and this filtrate is passed, in the subsequent adsorption stage, through a packed bed of ion-exchange fiber bodies, by which ZnCl2 alone is selectively adsorbed by the fiber bodies and the adsorption of bivalent Fe is prevented. Subsequently, water is passed through the fiber bodies to elute the adsorbed ZnCl2, which is introduced into an aqueous solution of Na2CO3 to precipitate the ZnCl2 in the form of basic zinc carbonate. This basic zinc carbonate is filtered, washed, dried, and oxidized by heating at about 600 deg.C, by which high purity ZnO can be recovered.

Title: Fully automatic batch-type refuse incinerator
Inventor: MORINO YOSHIO
IPC: F23G5/00
Filed: 1988-10-27
Abstract: PURPOSE:To allow a batch-type application to not only small size refuse incinerators but also large size incinerators by connecting the refuse storage and the ceiling of the furnace with a screw conveyer which is inclined at a shallow angle and is configured at its top in the same width as the roaster surface, and providing the conveyer outer shell with a water jacket device. CONSTITUTION:Since a screw conveyer 3 spans from the bottom of the refuse storage 1 to the top of the furnace body 2, the refuse drops all over the roaster 11 without concentrating in any one location of the roaster 11. As the roaster 11 is caused to oscillate, the refuse is incinerated in the furnace. The exhaust gas is led out of the secondary firing chamber 22, and, after reducing the temperature down to about 300 deg.C by means of a shower ring 25, etc., it is discharged outside by a fan 26 or is guided through a dust collector. A bypass pipe 27 is branched from a duct 23 to the top of the fan so that it can be used as a roasting furnace by switching a damper 28 for natural draft at the time of incinerating moist refuse. The ash dropping into the ash pit under the oscillating roaster is pushed into the ash chute by a piston 15 to be discharged to the outside pit.

Title: Casting method and device by twin belt caster of steel
Inventor: ASARI TAKASHI
IPC: B22D11/06
Filed: 1987-10-29
Abstract: PURPOSE:To approximately equalize the forming of the initial solidifying shell on upper and lower faces and to prevent the crack generation of the surface of a cast slab and the deformation of the cast slab section by delaying the growth of the initial solidifying shell of the lower face side by constraining the cooling capacity of a lower belt lower. CONSTITUTION:The thermal conductivity is made lower than that of an upper belt 4 by coating the poor conductor 12b of a ceramics, etc., on the belt 12a surface of a lower belt 12 in the casting by a twin-belt caster. A molten steel 8 is continuously cast in a strip plate like cast slab 9 inside molds 4, 12, 7 (7 is a dam block) by rotating the upper and lower belts 4, 12. A lower face solidifying shell 10 is started to grow on the lower face of the cast slab 9 but by the poor heat conductor layer 12b the growth of the solidifying shell is delayed. Even if the initial solidifying shell 11 of the upper face side is started to form the lower face side solidifying shell 10 has no force to constrain the shrinkage of the upper face side solidifying shell. The contraction amt. of the upper and lower solidifying shells 10, 11 is thus equalized and the shape accuracy of the cast slab is improved.

Title: Method and device for monitoring axis voltage of rotating machine
Inventor: WATANABE MICHIO
IPC: H02K19/36
Filed: 1984-12-25
Abstract: PURPOSE:To estimate the cause of the generation of the axis voltage of a rotating machine even during the operation of a rotating machine by taking a frequency analysis of the axis voltage and estimating the cause of the generation of the axis voltage on the basis of voltage values of respective frequencies. CONSTITUTION:The axis voltage A of a rotating axis 1 detected by a brush 2 for axis voltage detection is inputted to a frequency analyzing unit 7 through the buffer amplifier 4 of an axis voltage monitoring device 100 and a shaft voltage analytic signal consisting of voltages values of respective frequencies is inputted to an oscilloscope 8. At this time, when voltage values of the same frequency component with the axis rotation frequency, a higher harmonic component, a component twice as high as the commercial power source frequency, and a DC component are high, it is estimated that the generation of the axis voltage is caused by the unbalance of the magnetic circuit of an electric generator, wave voltage of an exciter for the electric generator, wave voltage of an grounding detection relay of generator field magnetism, and frictional static electricity. Further, a signal comparing unit 10 makes a comparison with the output of a frequency pattern storage unit 9 to judge whether the axis voltage of the rotating machine is normal or not.

Title: Controller for electrical discharge machine
Inventor: KURIYAMA TOMI
IPC: G05B19/18
Filed: 1988-10-27
Abstract: PURPOSE:To reduce a software load for giving and receiving data between respective units and to permit respective CPU in the units to concentrate one's whole mind upon a processing for original control by providing slave CPU provided in local control units, master CPU provided in a control unit and a first-in first-out register. CONSTITUTION:Data are given and received between the control unit 1 and respective local control units 2, 3 and 4 through the first-in first-out register 56. Since data are read in a written order in the FIFO register 31, CPU 11 and 21 of respective units do not need to control addresses. Since writing is prohibited when data become full, and reading is prohibited when data are eliminated in the FIFO register 31 by the function of the register itself, CPU 11 and 21 in respective units 1-4 do not need to operate flags. The operation of the addresses for giving and receiving data and a flag operation are unnecessary in CPU 11 and 21 in respective units 1-4. Thus, the software load is reduced and CPU can concentrate on the processing for original control.
