Title: Recovering method for superfine aluminium nitride particle
Inventor: BABA KAZUHIRO
IPC: C01B21/072
Filed: 1985-05-30
Abstract: PURPOSE:To obtain superfine AlN particles adsorbing no oxygen to the surface by dipping superfine AlN particles synthesized by high frequency induction plasma process in an org. solvent before the particles are discharged to atmospheric air. CONSTITUTION:Org. solvent 9 such as 'Chlorothene(R)' is poured on superfine AlN particles 10 synthesized by high frequency induction plasma process and collected in a recovering section using an illustrated device, and the particles are recovered. Prior to the pouring of the solvent 9, O2 dissolved in the solvent is removed by introducing inert gas into the solvent by closing a cock 5, opening a cock 6, and introducing the inert gas through a vinyl resin pipe 7'. If the solvent is easily soluble in water, the solvent is dehydrated previously to sufficient degree. When formation of particles 10 is completed, a valve 1 is closed, the recovering vessel is evacuated, then a valve 2 is closed, and a filter backwashing valve 3 is opened, and particles 10 sticking to a filter section 4 are blown down. Thereafter, the recovering vessel is again evacuated, a cock 6 is closed, a cock 5 is opened, and the solvent 9 is flowed into the recovering vessel by the pressure difference between the recovering vessel and a solvent vessel. The recovered particles 10 are then filtered and dried for ca. 1hr at ca. 50 deg.C in a vacuum drier.

Filed: 1977-09-29
Abstract: PURPOSE:To achieve the improvement in productiveity by opposedly disposing a pair of revolving rollers, which are provided with functions of rolling, forming and cooling and are provided with desired undulations, on the outside circumferential surfaces thereof at a desired spacing and number of revolutions and dropping molten amorphous metal in said gap part. CONSTITUTION:Metal rollers 5, 6 which are disposed with a spacing part 4 for giving the necessary thickness of the amorphous core are disposed in a suitable position below a crucible 2. The opposing outside circumferential surfaces of both rollers are made of such construction in which, e.g., the roller 5 is formed to approximately concave type 8 and the roller 6 to approximately convex type 9 and the concave and convex types are combined at a suitable spacing 4. Because of this, if the amorphous alloy 1 in a molten state is dropped throgh the nozzle 3 of the crucible 2 onto the rollers, it disperses in the concave and convex parts and isat the same time fed into the spacing part 4 where it is rolled and formed, after which it is quenched with the revolving metal rollers, whereby a strip amorphous alloy core 10 of and approximate U-shape is continuously obtained. Thereby, the cores of intricate shapes may be readily produced and productivity enhanced.

Filed: 1978-09-25
Abstract: PURPOSE: To make dies removable rapidly without using welding and obviate giving flaws to  products by dividing the roll die to two dies of the specific shapes of 180° or under and fitting  these with each other when the roll die does not permit fitting from the roll axis direction and is  180° or over in the angle that is assumes to the roll axial center in cross section.   
     CONSTITUTION: Since the angle θ that the roll die assumes to its roll axial center O is 180° or  over, the roll die is divided to a main die 3 and auxiliary die 8 whose angle is less than 180°.  First, the die 8 is fitted to the shaft 1 and its movement in the circumferential and axial central  direction is stopped by a fitting key 9 and a fixing device. Next, the die 3 is fitted from above  and is similarly fixed by a fitting key 10 and fixing device. The opposing faces of the die 8 and  die 3 have the slope 80 of about 30W45° in the angle α that they assume to the line A and an extending part 81 in the die 3 bottom direction from the bottom end thereof. The top surfaces thereof are the bottom surface 82 extending in the circumferential direction and the slope 83 aligning  to the perpendicular line C. The angles β that the line connecting the center of the face 82 and  the axis O and the faces 80, 83 assume are the same. The opposing faces of the 3 are approximately symmetrical to the abovementioned faces but the crest type face 31 is so arranged to  have a slight clearance from the face 82.

Filed: 1994-05-07
Abstract: PURPOSE:To estimate an echo path with high accuracy at high speed at the echo canceler provided at a telephone line network for performing transmission between sounds to be sent through four wire lines and sounds to be sent through two wire lines. CONSTITUTION:An echo path estimating/pseudo echogenerating circuit 3 is composed of an adaptive filter such as an FIR filter and when a near terminal sound signal Sin and a distant terminal sound signal Rout are inputted, a pseudo echo signal Y is outputted to cancel an echo component contained in the former. A delay time measuring circuit 71 measures the delay time of echo based on the signals Sin and Rout and based on this result, the delay time of a delay circuit 75 is set. On the other hand, a spectrum comparator circuit 73 designates any frequency response characteristic in a data base 74 based on signals Rout' and Sin and based on the designated characteristic, the tap coefficient of the FIR filter is set. Thus, the circuit 3 performs high-accurate echo estimation from the beginning.

Filed: 1986-05-22
Abstract: PURPOSE:To obtain an index signal having stable intensity, and besides to improve picture definition with reduced intervals of color phosphor dots by laminating index phosphors and a transparent conductive film on a color phosphor. CONSTITUTION:Index phosphors 3 are laminated on phosphors G. A transparent conductive film 2 comprising tin oxide, acting as an anode electrode, is laminat on color phosphors R, B, and the index phosphors 3. The color phosphors G, on which the index phosphors 3 are laminated, are illuminated excite when they are violet rays. The color phosphors R and B, on Which the index phosphors 3 are not laminated, are excited by an electron beam and they are illuminated. Therefore, even if the index phosphors 3 are made nearly as wide as the color phosphors R, G, and B, and even if mutual intervals among the color phosphors R, G, and B are made smaller than the widths of the index phosphors 3, that is, those of the color phosphors R, G and B, the index phosphors 3 cause no trouble on excitation of the color phosphors R, G, and B. Hence, picture definition can be improved, and an index signal having stable intensity can be obtained.
