Title: Ion exchange membrane*its manufacture and use
Inventor: JIYAN BASHIYO
IPC: B01J47/12
Filed: 1979-03-13
Abstract: A process for preparing membranes for electrolysis. One such process comprises impregnating a porous sheet comprising a polyfluoroolefin, asbestos fibers and an inorganic pore-forming agent with a solution comprising (i) a compound selected from the group consisting of acrylic acid and methacrylic and (ii) at least one other non-ionic monomer having at least one >C=CH2 group, withdrawing said sheet from contact with said solution, polymerizing the monomers which become impregnated in the sheet so that the pores of the sheet contain the resulting acrylic polymer, eliminating the inorganic pore-forming agent to form pores in the sheet, and swelling the acrylic polymer so that the pores of the sheet are closed by the polymer. The membranes produced by these processes are useful in cells for the electrolysis of sodium chloride to produce chlorine and sodium hydroxide.

Title: Surface acoustic wave convolver
Inventor: MITSUZUKA SHUICHI
IPC: H03H9/72
Filed: 1987-02-10
Abstract: PURPOSE:To obtain an excellent characteristic simply by including a semiconductor epitaxial layer, an insulation layer and a piezoelectric film including a 2nd conductor semiconductor film different from that for the substrate. CONSTITUTION:A 1st conductor high density semiconductor substrate 1, the semiconductor epitaxial layer 9 including the 2nd conductor type semiconductor film different from that of the substrate 1, the insulation layer 2 formed on the semiconductor epitaxial layer 9, and the piezoelectric film 3 formed on the insulation layer 2 are included. That is, since the type of the semiconductor for the substrate 1 and the film 9 differs from each other, a depletion layer 10 is spread naturally at its boundary. Since number of carriers in existence in the depletion layer 10 is smaller than the carrier at the surrounding part, even when a potential attended with the surface wave is applied to the depletion layer, the loss generated in the depletion layer 10 is very small. Thus, the effective film thickness of the semiconductor epitaxial film 9 is decreased by the width of the depletion layer 10. Thus, the difficulty in the manufacture of a SAW convolver is reduced and the monolithic SAW convolver having an excellent characteristic is obtained.

Title: Tracking method when developing event in continuous casting
Inventor: HASHIMOTO SHINJI
IPC: B22D11/16
Filed: 1995-02-17
Abstract: PURPOSE: To execute the control of cutting of a cast slab at high accuracy while correcting the deviation of a tracking by obtaining the stepping position of the cast slab from the variation of a load torque current value of a driving pinch roll in continuous casting. CONSTITUTION: In the tracking or the cast slab 4 in a continuous caster, the load torque current of the driving pinch roll 5 is measured. After the measured current value exceeds the present threshold value, the point of time changed to the fixed form is made to be the stepping position. By this method, the deviation developed in the conventional tracking method is corrected and the accuracy of the cutting position of the cast slab can be improved. Since the load torque current value of the driving pinch roll 5 in each continuous caster is different, the threshold value is necessary to set by experimentation, but ordinarily, this value can use about 50% of the load torque current value of the pinch roll 5 in the stationary condition.  Further, the point of time when the current value changes the form, is ordinarily desirable to be the point of time when the lowered current value changes upward.

Abstract: PURPOSE:To obtain an optical gate switch of normally-off by constituting a second semiconductor layer of a medium for decreasing a refractive index to a light beam to be modulated, by an electric field, so that the refractive indexes of first and second semiconductor layers are set to a specific relation. CONSTITUTION:On both sides of a layer of a refractive index n1, on which a light beam to be modulated is made incident, a layer whose refractive index n2 is decreased by an electric field is placed.

At the time of the electric field E>'0', the refractive index n2 decreases and a relation of n1>n2 (E) is obtained, and the incident light is confined in the layer of the refractive index n1, goes to a waveguide mode and propagated in an optical gate and can be fetched as the emitted light, that is, it becomes an ON state. In such a way, an optical gate of normally-off is obtained.
