Title: Continuous casting device for thin billet
Inventor: BETSUSHIYO NAGAYASU
IPC: B22D11/06
Filed: 1983-12-05
Abstract: PURPOSE:To minimize the adverse influence that the pouring flow gives to a thin billet in the stage of starting casting by providing a pouring port for a molten metal to either one of stationary plates for short sides. CONSTITUTION:A nozzle 11 is connected to either one or both of stationary side plates 6, 7 and pouring ports 11a... are opened. The molten metal in a tundish 12 flows through the nozzle 11 and through the ports 11a, thus entering the inside of a casting space S in the form of horizontal flow. Solidification progresses successively inward from the areas adjacent to metallic belts 4, 5 forming solidified shells in precedence, then the solidified billet is drawn out downward by a dummy bar and the rotation of the belts 4, 5. The level of the ports 11a which discharge the molten metal into the space S is thus made lower and the molten metal striking against the surface of the metallic belts in the initial period of pouring is considerably decreased. The erosion and thermal strain of the belts are thus eliminated.

Title: Optical pulse tester
Inventor: NAGAI NOBUAKI
IPC: G01J1/02
Filed: 1993-09-14
Abstract: PURPOSE:To eliminate the complicatedness of measurement while automating joining by measuring the quantity of the back scattered beam of a fiber to be measured several times and determining a measuring section so that the joint of an image joined so as to display the measured results of respective sections in equal magnification is not to be a stepped part where the output of an O/E converter changes suddenly. CONSTITUTION:A control device measures the back scattered beam of the determined section of a fiber to be measured not only to display the measured result on a display device 109 but also to store the same in an image processing part 110. Measurement is performed a predetermined number of times to repeat display and memory. Continuously, the amplification factor of a joining point and the section thereof is determined from the stored content to be set to the amplification factor of an amplifier 105. Next, the measurement of the total section is repeated and the waveform joining processing at the joining point is performed and the waveform of the intensity of the back scattered beam passed through the fiber is displayed on the display device 9. The detection of a stepped part is performed by comparing signal intensity with the intensity at the previous measuring point to monitor the same. By this constitution, joining can be performed automatically and the complicatedness of measurement can be eliminated.

Title: Color image receiving tube
Inventor: KOBAYASHI KENICHI
IPC: H04N9/28
Filed: 1985-10-16
Abstract: PURPOSE:To maintain an excellent convergence dignity even if a color image receiving tube is operated at a high horizontal scan frequency by flowing the 1st vertical deflection current to a coil wound on both side leg parts so as to generate a magnetic flux in the same direction as the vertical magnetic flux of a deflection yoke and flowing the 2nd vertical deflection current to a coil wound on a central leg part so that fluxes generated by each auxiliary coils can be positioned in the direction strengthening each other on an electronic gun array surface. CONSTITUTION:When the vertical deflection current flows in coils 3a-3d on the leg parts at both sides, magnetic fluxes 101 and 102 are emitted from the leg parts, and a pin cushion flux synthesized with the neck side flux of the vertical coil is formed. In the pin cushion flux, a deflection force 11 strongly acting on beams 5g, 5r and 5b more strongly acts on the center beam 5g than side beams 5r and 5b to correct a VCR. Deflection forces 131 and 132 caused by fluxes 121 and 121 generated by the coils 4a and 4b at the central leg part is reverse with respect to both side beams 5r and 5b, whereby an YV error can be corrected.

IPC: G01F1/00
Filed: 1988-09-12
Abstract: PURPOSE:To detect and measure the flowing state of molten metal in cavity with a simple constitution by detecting the arrival of the molten metal from the electrical short circuit produced when the molten metal comes into contact with one or plural contacts. CONSTITUTION:At the time of providing, for example, a belt-like insulating line with plural contacts1a provided at intervals in a cavity 3 as a detecting sensor 1, the insulating line is put into the cavity 3 from an air vent 7 and stuck to the surface 4 of the cavity so that the contacts1a can be scattered in the cavity. The flowing state of molten metal at each measuring point in the cavity 3 is detected by the electrical short circuit produced when the molten metal comes into contact with each contact1a. Therefore, producing of a detecting sensor having a complicated structure and boring works into the metallic molds, etc., for installing the detecting sensor become unnecessary and, at the same time, the measurement can be made at an arbitrary point.

Abstract: PURPOSE:To contrive to shorten a connection-waiting time for each earth station by dividing all the earth stations into plural groups each including plural earth stations, making each group call by TDMA system, and making each earth station in the group call by random access system with slot. CONSTITUTION:One frame on a common line is constituted of four time slots, and each totalized time slot consists of two small time slots. This means that, in one frame, the frame's first and second small time slots are allocated to the group 1, the third and the fourth small time slots are to the group 2, the fifth and the sixth to the group 3, and the seventh and the eighth to the group 4. Each group of the stations calls by means of TDMA(time division multiple access) system against the totalized time slot, and each station on the earth forming each group calls by means of random access system with time slot against the small time slot. As a result, the waiting time for line connection of each station on the earth can be shortened, and the common line can be used effectively.

Title: Method for polarizing bismuth layered compound
Inventor: KANEKO KAZUHIDE
IPC: H01L41/257
Filed: 1992-08-28
Abstract: PURPOSE:To enhance the sensitivity to piezoelectricity by a method wherein the title bismuth layered compound is polarized while being impressed with a specific pressure making a right angle with the polarising direction for polarizing the crystalline particles hardly polarized by prior art method. CONSTITUTION:The bismuth layered compound is to be composed of a material having extremely intensitive anisotropy and in specific polarizing direction due to the crystalline structure thereof. Thus, this compound is polarized while being impressed with the pressure exceeding 0.1MPa making a right angle with the polarizing direction. At this time, the grain boundary slip is made in crystalline particles 10 by the pressure in the easily polarizing direction, i.e., the extending direction of a flat surface making a right angle with the pressure impressing direction so that even the crystalline particles 10 hardly polarized by prior art method may be polarized. Accordingly, even if the impressed pressure is relieved to reset to the original state of the crystalline particles 10, the polarized state of respective particles 10 is to be left intact thereby enabling the sensitivity to piezoelectricity to be enhanced compared with the prior art one.
