Title: Mold closing device for continuous casting and continuous casting method using said closing device
Inventor: UEDA TARUO
IPC: B22D11/08
Filed: 1980-03-19
Abstract: PURPOSE: To enable casting to be started without using any dummy bar by inserting a closing device which constitutes a hollow rectangular parallelopiped opening at the top face into a mold in such a manner as to fit nearly in close contact therewith.  
     CONSTITUTION: A block 28 is projected from the inside wall surfaces of the long sides 6 of a mold and a closing device 31 is fitted to the mold 3 bottom and is supported by the block 28, whereby the mold outlet is closed. Connecting fittings and a chill are put into the closing device 31 and a sealig material is sandwiched between the inside walls of the mold. While the mold is being cooled as specifid by cooling water flow passages 13 and cooling water spraying nozzles, molten metal is flowed into the mold 3 and is cooled. When the solidified shell grows sufficiently thick, the block 28 is retreated up to the inside wall surfaces of the longer sides 6 of the mold plate. Driving rollers are turned to move a driving belt downward. At the same time, the mold 3 is moved vertically. Since the upper part of the ingot drawing device is gripping the closing device 31, the ingot having solidified in one piece with the closing device 31 is drawn downward.

Inventor: OKADA KATSUMI
IPC: G11B5/588
Filed: 1983-03-02
Abstract: PURPOSE:To allow a head to trace a recording track accurately by moving the head in the same direction with the rotational axis line of a rotary drum and utilizing a permanent magnet and an electromagnetic coil. CONSTITUTION:One terminal of an elastic member 15 which extends toward the direction crossing the rotational axis line of the rotary drum 3 is fixed thereto and the head 8 is fixed to the other terminal, so that the head 8 is movable in the same direction with the rotational axis line of the rotary drum 3. One terminal of a connecting rod 18 is fixed to a base metal 17 and the permanent magnet 19 is fixed to the other terminal. The electromagnetic coil 20 which generates an electromagnetic force to the permanent magnet 19 is arranged fixedly on the rotary drum 3. When a current is flowed to the electromagnetic coil 20 through a rotary transformer 9, the electromagnetic force operates on the permanent magnet 19 and the head 8 moves in the direction of the rotational axis line of the rotary drum 3. This operation is utilized to slide the head 3 in the direction of the rotational axis line of the rotary drum 8, tracing the recording track accurately in case of the oscillation of the drum part 1 and vertical movement of a magnetic tape.

Title: Desulfurinzing molten iron
Inventor: MIZUNO YUTAKA
IPC: C21C1/00
Filed: 1978-03-27
Abstract: PURPOSE:Inexpensive desulfurization by molten slag is effectively performed by simultaneously discharging molten iron and molten slag from the blast furnace. CONSTITUTION:Slightly before molten iron is discharged through the tap 1 from the blast furnace, the tap 2 is opened to discharge molten slag s. The slag s passed through the spout 4 to spout 3 to be mixed with the iron i from the tap 1 and advances to the skimmer 5 while desulfurizing the iron i. The slag s which is lighter than the iron i is stopped by the buffle 7 at the skimmer 5. The slag s is separated from the iron i and guided into the spout 6 and recovered by ladel or some other means. The iron desulfurized by the slag is passed under the baffle 7 and advances through the spout 3' to cast bed. The process thus desulfurizes from beggining to last by use of the slag s, providing the iron having a constant S content.

Filed: 1990-02-16
Abstract: PURPOSE:To facilitate the formation of a low-density foam having uniform and fine cells by further foaming a thermoplastic polyester resin foam of a degree of crystallinity of 30% or below repeatedly under specified conditions. CONSTITUTION:A thermoplastic polyester resin foam of a degree of crystallinity of 30% or below is again foamed by heating by contact with water at 60 deg.C or higher or steam under substantially atmospheric pressure, and the obtained foam is further foamed by heating by contact with a heating medium other than water at 100 deg.C or above. The thermoplastic polyester resin foam used as the starting material can be prepared, for example, by rapidly cooling a soft thermoplastic polyester resin foam just after being extruded and foamed with an extruder to its glass transition point or below. The tertiary foaming (with a heating medium other than water) can be performed repeatedly so far as the crystallinity of the foam is within 30%, so that a final foam having a high degree of foaming can be obtained.

Filed: 1990-02-20
Abstract: PURPOSE:To reduce a temperature rise of superconductive wire due to turburence to improve the safety of a superconductor as a whole by covering the external circumference of the superconductor with a stabilizing material, and filling helium(He) in the gap formed along that external circumference. CONSTITUTION:A superconductor is made up so that stabilizing material 2 covers the external circumference of a superconducting element wire 1 and a gap 3 is filled with helium 4 in a supercritical state of 2.27atm or more. As shown in the figure, a superconducting magnet is equipped with a superconductive coil 5 wound around a superconductor, a power source 6 connected to the coil 5 and a gas bomb 7 for supplying helium 4 into the superconductor. In the case of the superconductor so made up, the specific heat of the helium 4 is as much as 5-8J/gK, so that its heat capacity is great with the result that heat generated by turburance is much absorbed by not only the stabilizing material 2 and also the helium 4. An increase in heat of the superconducting element wire 1 caused by turburance becomes smaller than conventional so that the superconductive breakdown of each superconducting element wire 1 can be prevented to obtain a stabilized superconductive state.
