Title: Submerged nozzle for continuous casting
Inventor: SASAI KATSUHIRO
IPC: C04B35/10
Filed: 1990-09-18
Abstract: PURPOSE:To provide a submerged nozzle for continuous casting with excellent erosion resistance and spalling resistance by incorporating the specific wt.% of silica coated with alumina in terms of the silica into the alumina-graphite quality nozzle for casting molten steel. CONSTITUTION:The fused silica, feldspar, etc., are used for silica. The alumina coating is applied on this and this is contained at about 5-50wt.% in terms of the silica. In the case of <5wt.%, the spalling resistance being necessary to the submerged nozzle is deteriorated and in the case of exceeding 50wt.%, content of the alumina is relatively reduced and the erosion resistance is lowered. As the used raw material of graphite, natural flaky graphite is desirable, but any material generally used for refractory can be used if this has no so large ash content. Further, in the blending range of the graphite, about 5-50wt.% is desirable. In the case of <5wt.% thereof, the spalling resistance is deteriorated and in the case of exceeding 50wt.%, the corrosion to the molten steel and molten powder is lowered by oxidation of the graphite and elution of this into the molten steel. Further, there is a possibility to develop the nozzle clogging by high heat conductivity.

After the printing processing of the frames made to coincide with the identical printing condition is finished, the film is carried again and the printing processing of the frame made to coincide with the second printing condition is executed. In such a way, the carrying and the printing of the film are repeatedly executed for every printing condition. Then, when the printing processing of the whole frames is finished, the printing processing of the next film is executed.

Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide moving images maintaining the resolution of excellent appearance by fractal-compressing a work frame corresponding to a sequence and fractal-expanding the compressed work frame corresponding to the sequence. SOLUTION: Since a frame/(t) frame conversion device 112 temporarily stores the data of a series of the sequences of the frames of the moving images and prepares (t) frames, the (t) frames are taken out one by one from the conversion device 112 and sent to a fractal compression device 113. The compression device 113 successively fractal-compresses the data of the (t) frames by fractal encoding and the compressed data of the (t) frames are held in a fractal moving image storage device 114. In such a manner, compressed moving image data are stored in the storage device 114 and then, transferred and reproduced. In the case of expanding the moving image data, the processing of taking out and fractal- expanding the compressed data of the (t) frames of a series of the sequences is performed.

Title: Solenoid magnetic field type discharge lamp
Inventor: ARAKI KENJI
IPC: H01J65/04
Filed: 1991-09-26
Abstract: PURPOSE:To enhance the total efficiency of a lamp by enhancing the efficiency of an excitor coil. CONSTITUTION:A light emissive substance is encapsulated in a photo- transmissive bulb 10, and therein plasma discharge is generated by a high frequency excitor coil 20 arranged as surrounding the bulb, and thereby the light emissive substance is allowed to make light emission. In this solenoid magnetic field discharge lamp, conductors 21, 22 constituting the excitor coil shall assume a flat plate having a section which is flat in the direction across the coil axis. This increases the surface area to lessen the surface resistance, which lessens the current resistance to lead to enlargement of the heat radiating effect, and thereby the coil efficiency is enhanced. Because the flat surface of each conductor is arranged in the direction across the coil axis the rate of shutting the light emitted by the bulb is lessened.

Title: Position controller
Inventor: KATOU YOSHITO
IPC: G05D3/12
Filed: 1983-12-29
Abstract: PURPOSE:To improve the average mobile speed without deteriorating a repetitive positioning accuracy by applying directly a deceleration command signal from a positioning device to a drive circuit. CONSTITUTION:When it is detected by a comparator 13 that a difference between a present position data of a present position resistor 11 and an object position data of an object position register 12 reaches a prescribed value, its output is fed to a control circuit 14. The circuit 14 transmits a deceleration command signal S3 to a drive voltage generating circuit 4, the circuit 4 transmits a small drive voltage VD corresponding to a low speed command so as to bring an actuator 6 to a low speed state. When the deceleration state continues, the position data between the registers 11 and 12 are coincident. As a result, the circuit 14 generates a stop command signal S4 to the circuit 4 so as to zero the drive voltage VD. Since the signals S3, S4 are applied directly to the circuit 4, the signals are immune to the effect of the scanning time of a programmable controller 3 and the effect of the transmission time due to a serial transmission signal line.
