Title: Optical signal generator
Inventor: MASUDA TOMOHIKO
IPC: B41J2/44
Filed: 1991-07-01
Abstract: PURPOSE:To obtain an optical signal generator in which fluctuation of the amount of light is suppressed by suppressing the periodical fluctuation of the amount of light. CONSTITUTION:First and second focusing light transmitter arrays 30, 31 comprise a plurality of focusing light transmitters 30a, 31a arranged in zigzag in the longitudinal direction at a pitch of D/2. Each of the focusing light transmitters 30a, 31a has diameter of D. Focusing light transmitters having parabolic refractive index distribution from the center toward the periphery, for example, are employed as the focusing light transmitters 30a, 31a. The focusing light transmitter 31a in the first focusing light transmitter array 30 is shifted by half of the arranging pitch of the focusing light transmitter, i.e., a distance of D/4, in the arranging direction from the focusing light transmitter 31a in the second focusing light transmitter array 31. Consequently, fluctuations of the amount of light on the reflecting faces of the first and second focusing light transmitter arrays 30, 31 are offset each other resulting in suppression of periodical fluctuation.

Title: Pretreatment of molten iron
Inventor: UMADA HAJIME
IPC: C21C1/04
Filed: 1986-07-10
Abstract: PURPOSE:To efficiently prerefine a molten iron in a short period without inducing the temp. drop of the molten iron by subjecting the molten iron first to a desiliconization treatment then removing the molten slag formed in respective stages successively and continuously at the time of subjecting the molten iron tapped from a blast furnace to prerefining such as desiliconizing, dephosphorizing and desulfurizing. CONSTITUTION:The molten iron tapped from the blast furnace is treated with an oxidizing flux made of a compsn. consisting of Fe2O3, CaO, etc., to convert Si to SiO2 and to bring the same into reaction with CaO to form the stable slag in a torpedo ladle car or ladle. Such slag is discharged by a vacuum suction device. A slight amt. of the molten slag is left on the surface of the molten iron to prevent the cooling of the molten iron by heat dissipation. The molten iron is then put into a conveying vessel and the oxidizing flux similar to the oxidizing flux used at the time of desiliconizing is blown by gaseous N2 into the molten iron to oxidize P to P2O5 and form the stable slag with CaO. The slag is discharged by vacuum suction equipment after the dephosphorization treatment and the molten iron is subjected to the desulfurization treatment by reducing slag. The molten slag by such treatment is removed as well. The molten iron prerefined by the desiliconizing, dephosphorizing and desulfurizing treatments is fed to a steel making furnace such as converter, where the molten iron is subjected to decarburization refining. A molten steel is thus produced.

Abstract: PROBLEM TO BE SOLVED: To reduce redundancy of wiring width and optimize power supply wiring by calculating second wiring width at every power supply wiring, in such a manner that current capacity ratio calculated on the basis of first wiring widths is in a specified range. SOLUTION: In a CPU 12, a wiring which is an object to be optimized by changing wiring width and a wiring which is not an object are distinguished (step 41), power supply network analyzing process is performed (step 42), and whether or not wiring width of each power supply wiring exceeds current capacity is checked (step 43). When an object wiring infringes current capacity, power supply wiring design process is finished. When a wiring which is not an object does not exceed current capacity, the CPU 12 calculates current capacity ratio at every optimized wiring, the calculated ratio is accommodated in a sixth file 26 (step 44). The CPU 12 checks whether or not the current capacity ratio of each optimized wiring is in a specified range (step 45), and wiring width of an optimized wiring whose current capacity ratio is not in the specified range is corrected.  As a result, the optimum power supply wiring having little redundancy can be designed.
