Abstract: PURPOSE:To produce slag contg. amorphous materials at specific rates stably in the stage of cooling molten blast furnace slag by a dry system or the like by cooling the slag at specific cooling rates down to specific temps. thereafter cooling the same slowly stepwise down to specific temps. at a specific cooling rate. CONSTITUTION:In the stage of cooling molten blast furnace slag by a dry system or gas/liquid system, the slag is cooled quickly at >=20.0 deg.C/sec cooling rate down to 1,200 deg.C from right after the start of cooling by granulating the slag by the flow of gases or mists., and the hot wind thereof is recovered. Thereafter, the slag is cooled stepwise as slowly as possible at >=5.8 deg.C/sec cooling rate from 1,200 deg.C down to 1,100 deg.C, at >=2.5 deg.C/sec from 1,100 deg.C down to 1,000 deg.C, and >=0.3 deg.C/ sec from 1,000 deg.C down to 850 deg.C, and the hot wind is recovered. Thus the heat retained by the slag is recovered advantageously and easily, and the slag contg. >=95% amorphous materials is produced stably.

Filed: 1990-06-20
Abstract: PURPOSE:To improve startablity even when an engine is at low temperature by driving an air pump to accumulate pressurized air in an air cylinder after the engine starts, or except when the engine starts. CONSTITUTION:A fuel injection valve 1 is provided with an air jet exit part around the fuel injection part, which is adapted to mix pressurized air with fuel to promote atomization. Further, an air cylinder 4 for accumulating pressurized air, as a pressurized air supply device, an air pump 8 for supplying pressurized air to the air cylinder 4, a solenoid valve 5 installed to an air passage 3, are provided. In this case, a control unit 12 drives the air pump 8 except when the engine starts, to accumulate pressurized air in the air cylinder 4 and to open the solenoid valve 5 at the time of low temperature of the engine, including the time of starting the engine. Thus, since power of batteries is not used when the engine is started, load to the batteries is eliminated to prevent battery-exhaustion, and thereby there is no danger of reduction of cranking- rotating speed.

Title: Optical fiber light convergence correction equipment in solid laser equipment
Inventor: KOJIMA MINORU
IPC: H01S3/101
Filed: 1991-07-01
Abstract: PURPOSE:To automatically adjust light convergence on an optical fiber to be the optimum state, by detecting the spread state of a laser beam, adjusting a condenser lens to be at a suitable position, and moving the second actuator by the same distance. CONSTITUTION:The intensity distribution of a laser beam is detected with a detection part 8. Said distribution shows the spread state of the laser beam, and data are inputted in an operation part 12. When the spread state exceeds a specified region, a signal for driving an actuator 9 is sent out to move a detection part 8, and a condenser lens 7 for correction use is moved. Since the refraction position of the laser beam is changed, the spread state of the laser beam in the detection part 8 is changed. When the spread is in the contraction direction, the loop is repeated. Thereby the first actuator 9 is controlled as far as a position where the spread of the laser beam becomes minimum. When the area of the focus in the detection part 8 becomes minimum, this is judged to be the optimum state by the operation part 12, which drives the second actuator by the travelling distance amount of the first actuator 9.

Title: Production of strong and tough non-refined steel plate
Inventor: KATSUMATA MASAAKI
IPC: C21D8/02
Filed: 1981-10-07
Abstract: PURPOSE:To obtain a non-refined steel plate having much higher strength and toughness  than conventional products in techniques for accelerated cooling of steel plates after  hot rolling by controlling the cooling patterns specifically in a specified temp. range  after rolling. CONSTITUTION:After the hot rolling of a steel plate is finished, the steel plate is cooled  forcibly from the temp. for initiation of the cooling wherein Ar3 is a lower limit value  down to the temp. for stopping the cooling wherein Ms is a lower limit value. Here,  in a cooling stage RA1 of a fore stage from the temp. (t) above the Ar3 down to  around Ar1, the cooling rate is made higher than an average cooling rate (curve C) as  shown by a curve A. On the other hand, in a cooling stage RA2 of a post stage from  around the Ar1 down to a temp. t2 above the Ms, the cooling rate is made lower than  the average cooling rate. Then, the driving force that accelerates the formation of  nuclei for ferrite is increased in the fore stage. Further the stage from the formation  of ferrite up to the finishing thereof is quick, and the growth thereof is suppressed,  whereby fining is accelerated. The reason for decreasing the cooling rate in the post  stage lies in that it is effective to retard the cooling below the temp. for initiation of  bainite formation in order to decrease the condensing of C, Mn, etc. which contribute  to the formation of island martensite.
