Title: Countercurrent electrophoretic apparatus using strip like migration medium
Inventor: SAITOU KEIZOU
IPC: G01N27/26
Filed: 1983-02-07
Abstract: PURPOSE:To remarkably reduce power consumption required in separation and to perform continuous electrophoretic separation, by providing a mechanism for moving an ion migrating body while the insulation of the electrode solution adjacent to the direction opposite to the migration direction of a separated ion is held. CONSTITUTION:Feed rolls 11, 15 perform the countercurrent movement of an endless strip like migrating body 1 with respect to ion migration. In this case, an insulating substance 2 comprises, for example, an insulating heavy liquid having no affinity to electrode liquids 17, 18 each being an aqueous solution and having high specific gravity such as carbon tetrachloride or a polyhalogenated carbon liquid. Insulating partition walls 20-22 mutually insulate a treating liquid 16 and the electrode liquids 17-19 to form each electrode chamber. An ion is migrated through the migrating body part in the insulating heavy liquid by applying voltage to electrodes 23, 24. Because the ion migrating body 1 is countercurrently moved at a speed of about ten several mm. per one hr, it is reduced that the electrode solution is sent while adhered to the surface of the ion migrating body 1 at the interface of the electrode solution and the insulating heavy liquid. When the surface of the ion migrating body 1 has some water repellency, the electrode solution is hardly adhered thereto and it is convenient.

Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To effectively prevent generation of pre-echoes and post-echoes and to enable effective coding that employs an auditory psychology model. SOLUTION: Gain control circuits 103a to 103d detect the attacking and releasing parts of waveform signals and perform gain control on the waveform signals before the attacking parts and at the releasing parts by using gain controlled variables that are obtained adaptively according to the characteristics of the waveform signals.

Abstract: PURPOSE:To improve the dimensional accuracy of a material to be rolled through its whole length by setting vertical and horizontal rolls to the specific positions with respect to the logical center line of the material at every pass in rolling a shape steel by a universal rolling mill. CONSTITUTION:In case of rolling an H-beam, for instance, the center line 4c of a flange 4a i.e. its logical center line is made to coincide with a pass line 9 through the whole length of a material 4 order to eliminate the deviation of the 4c from the center line 4e of a web 4d. Then the rolling is performed by moving vertically universal rolls basing on the transferring surface 4a of the material 4 and making said pass line 9, determined by the relations of roll positions, coincide with an ideal pass line 9a (a line obtained from the flange width FW by setting the surface 6a as a base surface). Further, in this case, because not only the flange width but the web thickness are also changed at each pass, the vertically moving amounts of upper and lower horizontal rolls 3a, 3b are required to be different from each other, and also the vertically moving amounts of a pair of vertical rolls and the rolls 3a, 3b are often required to be different from each other.

Abstract: PURPOSE: To spot-weld steel plates without applying any pretreatment at all by holding the weld section of the superposed steel plates to be welded between the  electrodes of a spot welding machine under pressure and applying ultrasonic vibrations thereto then supplying welding current between the both electrodes.  
     CONSTITUTION: The portion where exists the superposed faying point of the plate materials to be bonded is placed on a cradle or electrode and is held under required pressure between the both electrodes or between the electrode and cradle, after which ultrasonic vibrations are applied thereto. Thence, welding current is supplied between the both electrodes or between the electrode and cradle through the plate materials to be welded and the superposed plate materials are spot-welded. Here, the plate materials to be welded are rubbed with each other by the application of the foregoing ultrasonic vibrations and the film of precoating, etc. is melted by the friction heat and is expelled to outside the faying point. In the case of rusted plates, the ultrasonic vibrations remove rust and flatten the finely undulated surfaces having been produced on the surface through rust formation to crean metal surfaces, thus the rust and removed metal powder may be removed to outside the faying point.
