Title: Production of sooty silica body, apparatus therefor and synthetic quartz glass using the same silica body
Inventor: YANAGIUCHI HIDEHIKO
IPC: C03B8/04
Filed: 1990-04-26
Abstract: PURPOSE:To enable suppression of homogeneity to a specific value or below by specifying the travel distance of a burner row in a method for relatively moving the burner row for producing fine silica particles and a target shaft. CONSTITUTION:A sooty silica body (hereinafter referred to as a soot body) of a prescribed length is deposited on a target shaft while relatively moving a burner row for producing fine silica particles and the target shaft. In the aforementioned method, the burner row is relatively moved at a uniform velocity through a travel distance over a range nearly equal to or more than the length (L) of a soot body to be produced in the shaft direction. The upper and lower dead points in conventional technology are eliminated to afford the objective soot body which is highly homogenized in the shaft direction with <=5X10-6 homogeneity. In this case, if the burner row is moved through a long travel range by reciprocating motion, a large-sized apparatus results. Thereby, methods for endlessly revolving the burner row along an ellipse having a distance in a straight line corresponding to the length (L), etc., are preferred.

Title: Heat insulated casting mold
Inventor: ISHIMATSU HIROYUKI
IPC: B22D3/00
Filed: 1982-06-25
Abstract: PURPOSE:To assure a sufficient rapping property, by covering a part or the whole of the inside surface of a casting mold with wooden materials. CONSTITUTION:The inside surface of a refractory material 1 of a heat insulated casting mold made of the refractory material for casting, for example, molten Fe-Cr is partly covered with wooden materials 5, 6.

Abstract: PROBLEM TO BE SOLVED: To judge reception without using a reception-judging register for judging address matching by a slave by transferring an address housed in a receiving register to the transmission register of the slave station of the slave after finishing data transmission to the slave station of the slave from the master station of a slave. SOLUTION: In the case of transmitting data to a slave 2 from a slave 1 by setting one of slaves to be the master station of a slave (slave 1) and one of the other slave stations to be the slave station of a slave (slave 2), an address stored in the receiving register of the slave 1 is used as the address of a communication frame. Then, after finishing data transmission from the slave 1 to the slave 2, the address stored in the receiving register of the slave 1 is transferred to the transmission register 606 of the slave 2. An address matching judging circuit 117 inputs an output signal from a transmission register 126 and an output signal from a reception pre-register 100 and when the address matches, outputs a matching signal to a judging signal 114.

Abstract: PURPOSE:To generate static magnetic field having the desired magnetic flux density distribution in width direction of long sides in a mold in continuous casting equipment. CONSTITUTION:At the time of controlling flow of molten steel by generating the static magnetic field on the mold from magnetic poles 9, 10 in the continuous casting equipment, the static magnetic field is generated over the whole widths of long sides 3 in the mold from a main coil 11, and the static magnetic field is generated at near short sides 2 in the mold from a first and a second auxiliary coils 12, 13. By controlling electric current conducted to the main coil 11 or the auxiliary coils 12, 13 so that the magnetic flux density distribution in the width direction in the mold becomes uniform, enclosure of non-metallic inclusion and bubble into the mold is prevented. Further, by controlling the electric current supplied to the above each auxiliary coil 12, 13 according to intensity of the molten steel flow in the mold, the suitable damping force is acted to imbalance of the molten steel flow generated with uneven clogging, etc., in a immersion nozzle discharging hole. By this method, entrapment of the non-metallic inclusion, etc., into the wide width cast slab is prevented.

Filed: 1994-04-27
Abstract: PURPOSE:To improve an earthquake-proof property at the time of track jump by making a tracking actuator drive output signal a detection input signal, comparing it with a prescribed value and performing the track jump only when they coincide with each other. CONSTITUTION:A jump timing detection device 11 inputs the tracking actuator drive output signal 6 at an exciting time as the detection input signal. A detection input signal fixed value comparison means 8 receiving the detection input signal compares the detection input signal with a prescribed fixed value. Only when they coincide with each other in the comparison result, a jump permission signal output means 10 outputs a jump permission signal 9 to a tracking servo device 5. Then, the device 5 outputs the drive output signal 6 to a tracking actuator driving device 7, and drives a tracking actuator 4 to jump. Thus, the track jump is executed in the state that force applied to the tracking actuator is fixed, and the stability of a track distance is secured, and the earthquake- proof property is improved.
