Title: Method for preventing aggregation of al2o3 in molten steel
Inventor: KAWACHI YUJI
IPC: C21C7/04
Filed: 1991-11-28
Abstract: PURPOSE:To perfectly prevent the aggregation and the coarsening of Al2O3 series inclusions and to obtain a steel material having excellent quality characteristic by adding Mg alloy having a specific Mg content into molten steel containing Si, Mn, Al and a specific C content. CONSTITUTION:The Mg alloy having >0.5wt.%-<=30% Mg content, e.g. Fe-Si-Mg alloy, Fe-Mn-Mg alloy, Fe-Si-Mn-Mg alloy, etc., is added into the molten steel containing Si, Mn, Al and >=0.2wt.% C content. By this method, as Al2O3 is reformed into Al2O3.MgO and the latter complex compound has smaller interface energy with the molten steel than the former compound, wettability of the latter is different compared with Al2O3 and the latter does not entirely become cluster. Further, at the time of reforming Al2O3 into Al2O3.MgO, the size is not made to be large. The Mg alloy can quickly progress the reforming action and in the case of exceeding Mg content to >30%, the reactivity is vigorous and at the time of adding the Mg alloy, the molten steel is spattered and further, in the case of <=0.5% Mg content, the reforming is not sufficiently progressed and both the cases are not desirable.

Inventor: MORI CHUZO
IPC: B26F1/14
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To easily process an edge, reduce punching force and prolong the life of the edge. SOLUTION: Both of peripheries formed in a V shape are made inclined with each other in the opposite direction by cutting one end of a square pillar in such a way that the ridge 8 of a rough in a V-shape is oblique with respect to both the peripheries 9, and cutting edges 7, 10 and 11 are thereby formed in both the peripheries 9. By this constitution, the cutting edges 7, 10 and 11 can thereby be processed with ease. In this case, by inclining the cutting edges 7, 10 and 11 mutually to the opposite direction so that press-cutting is performed along the inclination between the edges and lower edge the required punching force is thereby reduced. By press-cutting, the collision of the edges with the lower edge is cureidend and the life of each cutting edge can thereby be prolonged.

Title: Pulp sludge fuel
Inventor: SATAKE TAKEO
IPC: C02F11/00
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To obtain a stable cellulose-containing fuel composition which contains only small amounts of components harmful to combustion by using, as the raw material, a sludge which is recovered by treating a waste water sludge occurring in a waste paper recycling process with a warm alkaline solution, SOLUTION: An active alkali in an amount of 0.005-0.1 pt. (in terms of NaOH) is added to a dehydrated sludge (with a water content of 60%) in an amount of 1 pt. (solid content) separated from a waste liquor discharged in a waste paper recycling process so that the alkali concentration is 0.4-40 g/kg. The sludge is heated for 10-12 min for soaking and is separated and recovered from an alkaline mother liquor by filtration, sedimentation, or the like. The soaking treatment with an alkali solution enables the sludge to be recovered almost without causing the loss in amount, giving a stable sludge which has a stable viscosity and contains only small amounts of components, such as chlorine compounds or sulfur compounds, harmful to combustion. Thus, the obtained sludge is used as a material for fuel and e.g. is kneaded with asphalt.

Abstract: PURPOSE:To make the circuit scale nearly a half in comparison with a conventional circuit scale by realizing a desired computing element with two switches (one of them is a 1-bit switch), one adder and one accumulation register. CONSTITUTION:An accumulation register 105 stores the output of an adder 102 tentatively when a parallel load signal PL is logical '1' depending on the polarity of the PL being the output of a switch 104, aborts the output of the adder 102 when the PL is logical '0', outputs a value twice the data stored tentatively as other of the adder 102 when said tentatively stored data or its inverted output (-MSB) is logical '0' and (i) is not equal to '0'. Moreover, a value twice the data stored tentatively fed from the accumulation register 105 to the adder 102 is obtained by shifting the output of the accumulation register 105 by one bit to the left (toward MSB) and adding '0(zero)' to the LSB and it is not required to install especially a circuit capable of multiplication processing.

Title: Hot water/cold water mixing device
Inventor: EKI TOSHIO
IPC: G05D23/13
Filed: 1992-11-25
Abstract: PURPOSE:To keep the temperature of mixed hot and cold water at a target temperature without hunting it. CONSTITUTION:Temperature difference DELTAT between a target temperature TP and a mixed hot and cold water temperature TC is canceled by energizing a movable valve element for deciding the mixing ratio of hot and cold water by using a thermosensitive coil spring composed of a material to change a spring constant corresponding to the temperature. When the temperature difference DELTAT is not canceled only by temperature control due to the thermosensitive coil spring, the temperature difference T is canceled by performing feedback control. A gain K of this feedback control is set at a prescribed value K1 in an area (blocks U1, U3 and U5) where a rate DELTABK of change of the spring constant of the thermosensitive coil spring at a temperature T is not changed. The mixed hot and cold water temperature TC is kept at the target temperature TP without being hunted over all the blocks by setting the gain K at a prescribed value K2 smaller than the prescribed value K1 in an area (blocks U2 and U4) where the rate DELTABK of change of the spring constant is changed.
