Title: Pretreatment for dephosphorizing molten iron
Inventor: INOUE AKIHIKO
IPC: C21C1/02
Filed: 1990-03-23
Abstract: PURPOSE:To desiliconize and dephosphorize molten iron without reducing its C content at the time of blowing a flux and gaseous oxygen to preliminarily dephosphorize and refine molten iron by commencing the reduction of oxygen feed rate when the decarburization reaction of molten iron is started and stopping the reduction of oxygen feed rate when desiliconization is completed. CONSTITUTION:Molten iron 2 contg. 0.03-0.30% Si is charged to a molten iron ladle 1, and gaseous O2 is blown from an oxygen lance 4 to convert Si in the molten iron 2 to SiO2 which is then removed. Meanwhile, a CaO-based flux consisting of 40-90% CaO, 5-20% CaCO3 and 2-10% CaF2 is blown into the molten iron from an immersed lance 3 with N2 as the carrier gas to form a CaO-SiO2-based slag having high basicity, and P in the molten iron is oxidized to P2O5 and fixed in the slag as a stable compd. In this case, the decarburization reaction is initiated as the Si content decreases, hence the reduction of oxygen feed rate from the lance 4 is commenced at this time (T0) and stopped at time (T1) when the desiliconization reaction is finished. The molten iron thus desiliconized and dephosphorized and still contg. sufficient C as the heat source for the refining of steel making in the succeeding converter is sent to the converter, decarburized and refined into steel.

Title: Resetting circuit for electronic watch
Inventor: ODAGIRI HIROYUKI
IPC: G04G5/00
Filed: 1979-06-13
Abstract: PURPOSE: To inhibit an instantaneous reset signal generated due to impact and noise for an electronic watch and prevent erroneous operation of the watch by sampling the reset signal.  
     CONSTITUTION: When a signal is generated at a reset terminal a due to impact or noise, an AND gate 6 produces a logic product signal with a reset inhibit signal c from a driving circuit 3 and outputs it to the data terminal D and the reset terminal R of a D-FF 8a. Since the D-FF 8a becomes operating state with this signal but the fall timing of a signal 32Hz from a frequency divider 2 is displaced, the output Q from the D-FF 8a is reset as 0 to prevent erroneous operation for an electronic watch.

Thus a larger digit number can be applied for the multiplier. Furthermore, an addition is given with the output of other multipliers or adders by giving the digit shift to the addition output, and thus the digit number can be increased more for the multiplier. In that case, the same multiplier is given to the multipliers which perform multiplication simultaneously. Several multipliers are combined according to the digit number of the multiplier to obtain the output, and then several multiplications become possible at one time with combinations of multipliers.

Abstract: PURPOSE:To obtain a catalyst having a high dispersibility of active components, wherein scattering of sulfuric acid radicals is restrained at a low degree, by using compounds of aluminium group such as hydrated aluminium oxide, aluminium powder, etc., as fixing agents for sulfate radicals. CONSTITUTION:In a denitration catalyst comprising titanium oxides containing sulfate radicals, hydrated aluminium oxide, aluminium powder, cationic clay, etc., are used under conditions that the titanium oxides are hydrated as fixing agents for sulfuric acid radicals, wherein the immobilizing agents are added in such a way that the atom ratio of aluminium to sulfur contained in the titanium oxides comes into a range of about 0.3-0.67 to effect a heat treatment under wet conditions, causing the sulfate radicals contained in the titanium oxides to react with the additives so as to produce aluminium sulfate. In this manner, the extent of scattering of sulfate radicals during sintering in the manufacturing process of catalyst and in use thereof can be made low, while alkali poisoning of catalyst activity is avoided, resulting in a high dispersion of active components and a high performance.

At this moment, one of swing arms 11, the horizontal section of which faces each other, is driven linked with the movement of another adjacent one of the swing arms 11, because the rotation of one of the shaft 10 causes another one of the shafts 10 to rotate simultaneously by the medium of No.1 gear 22 meshed with No.2 gear 23. Accordingly, the two swing arms 11 are arranged in closely spaced relation to each other, and can be driven by a single driving power source.
