Title: Electrolytic cell for chloride alkali electrolysis and electrolytic method
Inventor: SHIMAMUNE TAKAYUKI
IPC: C25B9/19
Filed: 1993-02-26
Abstract: PURPOSE: To enable the use of a gas cathode which is heretofore unusable for alkali chloride electrolysis in the alkali chloride electrolysis of a gas cathode as this cathode does not have resistance to a thick aq. alkaline hydroxide soln.  
     CONSTITUTION: The cathode chamber 4 of the alkali chloride electrolytic cell 1 segmented from an anode chamber 3 by a cation exchange member 2 is segmented to a soln. chamber 7 where the thick aq. alkaline hydroxide soln. exists and a gas chamber 10 where the gas cathode 8 is housed by an anion exchange member 6. The gas cathode 8 is prevented from coming into direct contact with the aq. alkaline hydroxide by the presence of the anion exchange membrane 6. Further, the longer life of the gas cathode may be achieved without indirect contact by the prohibition of the leakage of the aq. alkaline hydroxide into the gas chamber 10 by the anion exchange membrane 6. Further, the leakage described above may be prevented even if the electrolytic cell is formed to a larger size and, therefore, this process is applicable also to the electrolysis in an industrial scale which cannot be heretofore achieved with the conventional gas electrode.

Abstract: PURPOSE: To accurately determine the characteristic through simple operation, by connecting a DC power source to the ground side of the gapless arrester and measuring a direct current flowing through the arrester.  
     CONSTITUTION: A capacitor 12 is coupled in series with the gapless arrester 10 and grounded. A DC high-voltage power source 14 and a short-circuit switch are connected in parallel with the capacitor 12. An ammeter 18 for DC measurement is connected to a circuit of the power source 14. The capacitor 12 is set at such a capacitance as to produce impedance which is very low as to an alternating current which flows through the gapless arrester 10. A prescribed DC voltage EDC is applied between the arrester and the ground. At that time, a direct current IDC supplied from the power source 14 is measured by the ammeter 18 so that the increase in a corresponding-to-resistance current, which is used as a means of determining the characteristic of the arrester 10, due to the installation of the arrester can be directly read. The DC voltage EDC is varied to find out its relation to the direct current IDC by the ammeter to determine a non-linear coefficient α.

Abstract: PROBLEM TO BE SOLVED: To eliminate erroneous discharge, to reduce electric power consumption of a high voltage amplifier, and to reduce thermal stresses influencing peripherally mounted parts by making electrode driving voltage to have predetermined voltage, a predetermined waveform, and a predetermined timing. SOLUTION: An original signal of a discharge electrode driving waveform is non-invertibly amplified by transistors 3, 4 of a differential amplifier and current mirror transistors 1, 2, and current-amplified by a transistor 5 for a current amplification. An emitter current of the transistor 5 for the current amplification is produced by a transistor 13 and a resister 14 composing a current source. The current of the differential amplifier is produced by a transistor 10 and a resister 12 composing a current source, and the bias voltage of the two power sources is determined by a power source 11.  Thus, if an original signal of a desired discharge electrode driving waveform is inputted to the differential amplifier, it is possible to obtain a discharge electrode driving waveform with a desired amplification factor and obtain an optimal discharge electrode driving waveform corresponding to dispersion of PDP, reducing an erroneous discharge occurrence rate, and improving contrast.

Title: Electromagnetic flow coupler
Inventor: GOTO TADASHI
IPC: H02K44/06
Filed: 1987-03-18
Abstract: PURPOSE:To permit the regulation of the flow rate ratio of fluid in a first flow passage to the fluid in a second flow passage arbitrarily, by a method wherein the strength of a first magnetic field, corresponding to the first flow passage, is set so as to be higher than the strength of the second magnetic field, in the first and second flow passage, arranged in the magnetic field in parallel to each other. CONSTITUTION:When electroconductive fluid is made to flow through a generator passage 4 from outside, in an electromagnetic flow coupler, an annular electromotive force, orthogonal to the flow direction of the fluid and the direction of a magnetic field BG, is generated. This electromotive force is impressed on a pump flow passage 5 whereby the electroconductive fluid is provided with the power of flowing. The value of the flow rate QP of the fluid, flowing through the pump flow passage 5, is shown by a formula (here; B is flux density, Q is flow rate, appendix G shows the side of generator and appendix P shows the side of pump). Accordingly, the flow rate the side of the pump may be made larger than the the side of the generator by a method wherein the flux densities BP, BG are determined with respect to a desired flow rate ratio QP/QG so as to have a relation which satisfies the formula in a diagram.

Title: Method for sintering liquid phase of metal powder
Inventor: KONO MASAKI
IPC: B22F3/10
Filed: 1987-03-18
Abstract: PURPOSE:To reduce density difference in sintering and structure difference in each treatment by bringing the other thermocouple than the thermocouple for controlling sintering temp., into contact with a material to be sintered, detecting the development of liquid phase in the material to be sintered from variation of temp. measuring indication and stopping rise of the temp. CONSTITUTION:Temp. control in the sintering furnace is executed based on the temp. by the thermocouple for controlling the furnace temp. and the other thermocouple is directly brought into contact with the material to be sintered. When the temp. of the material to be sintered rises at the sintering operation, the indicating temp. of the thermocouple directly brought into contact with the material is varied. From this variation, the development of the liquid phase in the material to be sintered is detected. In accordance with the detection, immediately the rise of temp. in the furnace is stopped, and the temp. is kept, to continue the sintering for the prescribed time. By this method, the variance of the sintered density and the structure at each sintering treatment are reduced.
