摘要： PURPOSE: To improve the high current density and the S/N ratio by forming a plurality of infinitesimal patterns of conductor in which electrochemical reaction of substance to be measured easily occurs on a conductor in which the reaction scarcely occurs. CONSTITUTION: In the case of a conductor in which electro-chemical reaction scarcely occurs in substance to be measured such as hydrogen peroxide, as a conductor material in which the reaction easily occurs, a combination of metal having large electrochemical reaction velocity of hydrogen peroxide such as platinum, cobalt and other metal semiconductor such as carbon is included. As a method for forming a fine electrode pattern having 10μm or less on a conductor, since the conductor in which the reaction of the substance to be measured does not occur is substrate electrode, fine electrode pattern aggregate (fine array electrode) is formed on an insulating board by a plating method. Accordingly, since the substance to be measured is concentrically diffused on the fine electrode, a high current density is obtained. The substance to be measured is not reacted at the part except the patterns, and base line noise is extremely low. As a result, the S/N ratio is improved.

摘要： PURPOSE: To efficiently undergo photo electrochemical reaction by forming a photo electrochemical cell with a plurality of patterned thin film electrodes formed on an insulating transparent substrate, and constituting the thin film electrode by closely arranging a transparent electrode and an opaque electrode and electrically insulating them. CONSTITUTION: A light transmitting electrode 2 and a light non-transmitting electrode 3 are arranged at minute intervals on an insulating transparent substrate 1. The electrodes 2, 3 are connected to an outer circuit through electrode terminals 5, 6 to take in and out current and voltage. The electrode terminals 5, 6 and the electrodes 2, 3 are covered with an insulating layer except for the contact part with a solution to prevent generation of electrode reaction in a lead part. A container 4 is constituted so that the electrode surface of a photo electrochemical cell comes in contact with an inner solution and light is introduced from the back surface of the photo electrochemical cell. A photo electrochemically active solution is put in the container 4 and light is irradiated to the back surface of the photo electrochemical cell to realize a photo cell or a photo sensor by photo electrochemical reaction.

摘要： PURPOSE:To prevent thermal decomposition of organic substance at a time of vapor deposition and to enhance the orientation properties and crystallizability of a thin film by dropping the prescribed amount of the organic substance on a previously heated vapor deposition boat and quickly evaporating it in vacuum and vapor-depositing it to form the organic thin film. CONSTITUTION:The inside of a vacuum tank is regulated to about 10 Torr degree of vacuum and Al is vapor-deposited at about thousands Angstrom on a glass base plate 1 in a preliminary chamber 6 with a resistance heating vapor deposition device 2. Then after introducing oxygen and forming aluminum oxide with glow discharge, it is transferred to a formation chamber 5 of an organic thin film. Then argon atomic beams are subjected to impulse toward the base plate for vapor deposition from a generator of the atomic beams for shocking the base plate. The powder of N-salicylideneaniline-3-carboxylic acid is allowed to fall on a heated tungsten boat from a falling device 7 of organic substance and all amounts are quickly evaporated. Then after returning the base plate to the preliminary chamber 6, a lead electrode is vapor-deposited by using the resistance heating vapor deposition device 2.

摘要： PURPOSE:To obtain an organic tunnel element enabling both operation of switching and memory and having excellent memory characteristics by using a proton shift type organic compound for an insulating layer and arranging the proton shift type organic compound in the dircetion of an electric field generated from a pair of electrodes in the insulating layer. CONSTITUTION:A first electrode 2 is formed onto a substrate 1, an inorganic insulating layer 3 surrounding the electrode on the substrate 1 and an organic insulating layer 12 consisting of a proton shift type organic compound are shaped to the upper section of the first electrode 2 as insulating layers, and a second electrode 4 is formed to the upper section of the layer 12 so as to hold the insulating layers 3, 12 together with the electrode 2. The organic compound is oriented in the direction of an electric field, the vertical direction to the substrate, from the electrode in the insulating layer including the proton shift type organic compound. The inorganic insulating layer consisting of a material, the surface of which has hydroxyl groups and which is composed of Al2O3, etc., is shaped to the lower section of the insulating layer in order to generate such orientation, and an organic acid induced from the proton shift type organic compound is introduced to the upper section of the inorganic insulating layer, thus reacting the functional group of the organic acid with the hydroxyl group, then arranging the acid group of the organic acid in the fixed direction.
