Title: Solvent mixer for liquid chromatography
Inventor: INOUE YOSHINORI
IPC: B01F5/00
Filed: 1988-12-21
Abstract: PURPOSE:To improve the efficiency of mixing with a simple structure by using a mixing coil which is a capillary of a small bore and is inserted with packing materials consisting of wires. CONSTITUTION:A mixing block 1 is so formed that 3 or 4 solvents can be mixed. The block is formed in such a manner that the respective solvents join by passing the radial flow passages on the same plane and flow out perpendicularly toward an inlet flow passage 1a in order to enhance the mixing efficiency in the block. A filter to prevent the outflow of the packing materials is attached to an outlet flow passage 7a. The bore of the capillary tube is specified to 0.5 to 1.5mm and the mixing efficiency is maintained by avoiding the large difference in the bore between the solvent after joining and the piping. The mixing coil 4 is formed by doubling and twisting composite pieces of the wire rods having 0.1 to 0.5mm diameter to form the packing materials and inserting the packing materials into the tube. The mixer is constituted by connecting this coil 4 and the block 1.

Title: Apparatus for capturing matter wandering in secondary circuit of steam generator
IPC: G21D1/00
Filed: 1992-12-02
Abstract: PURPOSE: To limit the size and number of wandering matter causing damage on a pipe group by arranging a plurality of grids or filtering systems on the entire annular cross-section of the secondary circuit of a steam generator, in the downstream of a water supply pipe therefor, and in the upstream of water being introduced into the pipe group of primary circuit. CONSTITUTION: Although a grating 16 is shown at a horizontal position, it must be spread functionally over the entire crosssection of the return path of water and it is arranged by a bracket 19 fixed to the upper outer surface 17. Since the width L of the grating 16 is slightly narrower than the width S of the return path of water at that position, a space 20 is left between the grating 16 and the inner surface 18 thus allowing expansion due to temperature difference between an envelope 7, the grating 16 and the bracket 19. Outer stripes 21 fixed to the outer circumference of the grating 16 prevent the secondary water from being introduced again between the grating 16 and the envelope 7 due to a matter captured by the grating 16. Inner strips 22 are arranged between the grating 16 and the upper part 10 of pipe group envelope and fill conical or tubular gap being left.  Similarly, outer stripes 30 fill the gap between the grating 16 and the envelope 7.

Title: Shadow mask of color cathode-ray tube
Inventor: GOTOU TOKUNORI
IPC: H01J29/07
Filed: 1989-12-15
Abstract: PURPOSE:To prevent a phenomen to be spherical of a sticking film and doming of a mask by sticking an alloy of bismuth and nickel to the main surface on the side of an electron gun of a shadow mask. CONSTITUTION:A blackening film 3b is stuck to both sides of an aluminium killed steel plate 3a for rust-proofing and improving a thermal radiation rate, and a nickel-bismuth alloy layer 3c is stuck on the blackening film 3b of the face on the side of an electron gun of a shadow mask 3. A melting point of this alloy becomes 450 to 650 deg.C in the proper ratio while becoming almost around two times of that of metal bismuth. Accordingly, a stuck bismuth-nickel alloy fully stands a temperature about the maximum 450 deg.C in a manufacturing process while being excluded to become a liquid phase. After finishing a cathode-ray tube, the side of an electron gun of the shadow mask is in a state of a solid phase having relatively low thermal conductivity so as to relatively well reflect impacting electrons. Thereby, a phenomenon to become spherical of the stuck alloy film is prevented while preventing doming of the shadow with good efficiency.
