Title: Synchronous pulse generator
Inventor: MAEHASHI YUKIO
IPC: G06F13/42
Filed: 1980-02-13
Abstract: PURPOSE:To obtain a synchronous pulse generator that is free from any malfunction even with a high-speed input pulse and is suited for an integration, by producing the synchronous pulse synchronizing with the clock pulse CLP through a synchronous means after counting the asynchronous pulses up to a prescribed number. CONSTITUTION:The asynchronous input pulse signal of 8 pulses is applied to the terminal A of the T-type FF1. The waveforms are shown in the diagram respectively for the T-type FF1-3 and 9, the D-type latches D-L6 and 7 plus the outputs B-D, J, G, H and I of the AND gate 8 each. At the moment when the output D changes to the level L from H with the 8th pulse, the FF9 is set. The output J turns to ''H'' from ''L'', and the output of D-L6 delivers ''H'' with the timing of CLPphi2 within a computer. Then the output of D-L7 delivers ''H'' with the timing of CLPphi1. Thus the input pulse count end signal synchronous with phi1 is obtained. Then the output I becomes ''H'' as soon as the output of D-L7 becomes ''H'', and the initialization is given to the FF1-3 and 9. Thus the counting is possible for the next input pulse.

Title: Manufacture of synthetic wood
Inventor: NIITSUMA FUJIO
IPC: B29C61/00
Filed: 1981-02-06
Abstract: PURPOSE:To a synthetic wood resembling natural wood with respect to appearance and properties, having a grain-toned pattern and excellent mechanical strength in vertical direction, by a method in which a sheet material is wound around a core material and the core material is cut vertically so as to expose the cut section of the sheet material to the outside.

Title: Auto-focus device for video camera
Inventor: ITO YUJIRO
IPC: G03B13/36
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To surely decide the moving direction of a focus lens by calculating the 1st and 2nd evaluation value groups while carrying out a wobbling action and changing the importance of evaluation value of at least 1st or 2nd evaluation value group to decide the value in several times. SOLUTION: When a just-pin state is decided and a near or far state is not decided by the decision of 1st step, the moving direction of a focus lens cannot be decided. That is, a large out-of-focus degree is decided. Thereby, the importance of evaluation value is changed to slightly heighten the sensitivity and the decision of 2nd step is started. In other words, only the evaluation value of the working data having the comparatively high cut-off frequency is used in fact to contribute to the decision of 1st step in terms of importance of the evaluation value. However, the importance of valuation value is changed with the importance given to the evaluation value of the working data having the comparatively low cut-off frequency. That is, a near state is decided after the change of importance. Then a far state is decided if no near state is decided.

Next, the materials 1 are received by a second lift belt conveyer 5 and transferred in the direction orthogonal to the transferring direction of the roller conveyer 2. A switch detects the approach of the material 1 to the delivery side end of the second lift belt conveyer 5 to lower said conveyer 5 so that the leading material 1a of double rows of materials 1 abuts against a guide body 7 to be disposed on a single row of transfer flow path on the other end of said conveyer 2.

Title: Manufacture of magnetic particulate
Inventor: OGATA YASUNOBU
IPC: C01G49/00
Filed: 1984-02-02
Abstract: PURPOSE:To realize fine and equalize grains even though extremely simple heat treatment by adding a specific admixture to a glassy oxide solid phase as a starting substance in a solid phase deposition method. CONSTITUTION:Fe2O3 and one kind or two kinds or more of PbO, BaO, SrO and Ca and B2O3 as flux and SiO2 and Al2O3 are mixed, melted and quenched, thus forming a glassy solid. Particulates are deposited in the solid through heat treatment. Grain size is made smaller than a solid in which SiO2 and Al2O3 are not added, and hexagonal particulates having uniform grain-size distribution are obtained. A range of 0.1-20mol% is available as the addition rates of SiO2 and Al2O3. The addition of SiO2 of 20mol% or less results in the lowering of saturation magnetization and the irregularity of the shape of particulates.

Abstract: PURPOSE: To separate and capture oxide base inclusions in metal sample efficiently by electrolyzing the metal  sample contained in the inner bath of an electrolytic bath between the same as anode and the cathode of the  outer bath side and magnetically separating the deposits in the inner bath then sieving the same.   
     CONSTITUTION: Metal sample 10 is held to the anode 5 consisting of a magnet put on with a platinum cap 7  and is put in the inner bath 1 of a cylindrical electrolytic bath which is disposed with a metal screen on the side  faces and whose bottom is of funnel form. Electrolysis is then performed between the same and and the cathode  12 on the outer bath 11 side. Upon completion of the electrolysis, the sample 10 is removed, the inner bath 1 is  taken out and the deposits together with a small amount of electrolyte within the funnel form part are transferred into another vessel, where magnetic matter is magnetically separated and removed. Next, the dispersion  of the abovementioned deposits is poured onto plural sheets of sieves 15 of different meshes which are so laminated as to become coarser in mesh as they go uperward. The dispersion is then drawn through a suction bottle  17, whereby the deposits are sieved. Following to this, measurements for each grain size are accomplished and  the oxide base inclusions in the sample are analyzed. The rate of electrolysis of the sample is calculated from the  weight differences of the sample before and after the electrolysis.
