摘要:
An ion exchange membrane electrolytic cell comprises an anode, a cathode, an anode compartment and a cathode compartment partitioned by an ion exchange membrane. A gas and liquid permeable porous non-electrode layer composed of non-oxide ceramics particles is bonded to at least one side of the ion exchange membrane. With use of such a membrane, the cell voltage can considerably reduced in the electrolysis of water, an alkali metal halide, an alkali metal carbonate, etc.

A plate of a semiconductor having a narrow energy gap such as InSb, is applied with a magnetic field in parallel therewith and further supplied with a current in parallel therewith also as well as across the magnetic field, whereby an infrared radiation can be emitted perpendicular thereto in a wide range of temperature from room temperature to liquid nitrogen temperature.Consequently, an infrared emitting device, for instance, an infrared laser diode can be fabricated and operated at room temperature without necessity of a dewar filled with refrigerating material such as liquid nitrogen. Various kinds of compact infrared-emitting equipments such as an infrared radar can be realized by modulating the current supplied to the above infrared emitting device.
摘要:
A porous cathode for electrolysis of an alkali metal chloride comprises a substrate and a coating comprising, a catalyst, a water repellent material and a pore forming agent. The water repellent material is a combination of a first fluorinated resin having a particle diameter of 0.1 to 20.mu. and a melting point of 300.degree. to 340.degree. C. and a second fluorinated resin having a particle diameter of 1 to 50.mu. and a melting point of 160.degree. to 320.degree. C. and said first resin has higher melting point than that of said second resin.
摘要:
An electrolytic cell has a gas-liquid permeable porous electrode layer on a cation exchange membrane. The electrode layer is formed by printing a paste comprising an electrode powder on the surface of said cation exchange membrane by a screen printing process and bonding it.
摘要:
A gas diffusion electrode is used as a cathode for an electrolysis of an alkali metal chloride or an electrode in a fuel cell etc. A gas diffusion electrode has a porous layer made of a sintered mixture of a filler, a catalyst and a hydrophobic material which is formed by decomposing a pore forming agent selected from the group consisting of nickel, cobalt or iron salts of a carboxylic acids which is incorporated in a mixture of said filler, said catalysts and said hydrophobic material.
摘要:
A gas and liquid permeable cathode is bonded on an ion-exchange membrane and the composite electrode is used in an electrolytic cell for a production of sodium hydroxide by an electrolysis of an aqueous solution of sodium chloride. The cathode comprises a thermally decomposed nickel obtained from a nickel salt of fatty acid, Raney nickel, stabilized Raney nickel or carbonyl nickel and a polytetrafluoroethylene.
摘要:
An ophthalmic treatment method for inhibiting death of retinal constitutive cells of an eye by stimulating the cells includes a first step of placing a positive electrode and a negative electrode in such positions outside the eye that the electrodes provide electrical stimulation to the cells, at least one of the electrodes being placed on one of a cornea and sclera of the eye; and a second step of generating an electrical stimulation pulse having an electric current set at 20 μA or more but not exceeding 300 μA from each placed electrode.
摘要:
An opening is formed in a case. Air is caused to flow through the interior of the case. A panel closes the opening. A printed circuit board is disposed behind the panel within the case. A plurality of components, including a control device which can be operated on the front surface of the panel and a display device providing a display viewable on the front surface of the panel, are mounted on the printed circuit board. The printed circuit board is enclosed in a closed receptacle disposed within the case.
