摘要： PURPOSE:To make it possible to produce a positive side electrode and a negative side electrode for a plastic battery at a time, by covering a conductor to be the negative side electrode with a filter with a specific scope of filtering capacity when a positive side electrode is produced. CONSTITUTION:In an electrolytic cell 1, an electrolytic polymerization solution 2 is housed. In the solution 2, a collector 3 is placed, and at the opposite position of the collector 3, a conductor 4 is furnished which is covered by a filter 5. Furthermore, at the collector 3 side, a leading wire 7a connected to the positive side of a DC power source 6 is furnished, while at the conductor 4 side, a leading wire 7b connected to the negative side of the DC power source 6 is arranged. By applying a DC current between the both bodies 3 and 4 to carry out the electrolytic polymerization, a membrane of a conductive highpolymer material is separated at the collector 3 side, while a membrane of lithium is formed at the conductor 4 side through the filter 5.

摘要： PURPOSE:To provide an improvement in life by executing a dedoping by switching the polarity of an impressed voltage at every time when the charge quantity for polymn. energized on both electrodes attains the prescribed charge quantity for polymn. at the time of forming the thin film by an electrolytic oxidation polymn. of an oxidation polymerizable material on the surface of a deposition electrode. CONSTITUTION:An electrolyte 2 prepd. by dissolving an electrolyte and the oxidation polymerizable material in a solvent is put into an electroytic cell 1. The deposition electrode 3 and a counter electrode 4 are immersed therein. The polymn. is effected by disposing a 1st transparent substrate formed with an ITO (Indium Tin Oxide) thin film on the surface as the deposition electrode 3 and the counter electrode 3 formed of an Al sheet so as to face each other and connecting the deposition electrode 3 as an anode and the counter electrode 4 as a cathode by lead wires 5 to a constant voltage/constant current power source 6. The connection of the lead wires 5 is then switched to impress the voltage of reverse directions to both the electrodes 3, 4 to execute the dedoping of the film on the deposited electrode 1 obtd. by the polymn. The dedoping is executed before the charge quantity for polymn. attains the prescribed quantity at this time. The high-polymer thin film of the prescribed charge quantity for polymn. is formed by the repetition of the above-mentioned operations. The life is improved in this way.

摘要： PURPOSE:To give a concentration distribution of a photochromic material to a resin film by immersing it in a specified solution and varying the immersion time according to the part of the film. CONSTITUTION:A photochromic material (a), desirably, a spirooxazine derivative is dissolved in a liquid (b) (e.g., toluene) in which a resin film (A) (e.g., ethylene/ vinyl acetate film) swells to form a solution (B). Said film is immersed in component B so that the immersion time may vary according to the part of the film. For example, this immersion is performed in such a manner that the margin of component A is first slowly immersed and the its center is then immersed and that the center is first slowly pulled up and the margin is lastly pulled up. In this way, a concentration distribution of component (a) can be given to component A to form the title shaded band.

摘要： PURPOSE:To generate polypyrrole having good film quality and high conductivity and obtain a plastic cell having a high positive electrode capacity per area under the low-temperature condition by using acetonitrile as an organic solvent, dissolving pyrrole as a conductive polymer material in the organic solvent, and feeding a current to an electrolysis polymerization liquid dissolved with an electrolyte at the specific temperature condition for electrolysis polymerization. CONSTITUTION:A current collector is connected to the positive electrode side of a power supply, a conductor facing this current collector is connected to the negative electrode side of the power supply, the current collector and the said conductor are immersed in an electrolysis polymerization liquid, and a constant current is fed between them for electrolysis polymerization. Acetonitrile is used as an organic solvent, and pyrrole as a conductive polymer material is dissolved in the organic solvent. A current is fed to an electrolysis polymerization liquid dissolved with an electrolyte at the temperature condition of -40--15 deg.C for electrolysis polymerization. When the electrolysis polymerization temperature becomes-15 deg.C, the speed of polymerization reaction is made slow, and polypyrrole having good film quality and high conductivity is generated, thus the temperature is kept at -15 deg.C or lower. At the temperature lower than -40 deg.C, the organic solvent is frozen, thus the temperature is kept at -40 deg.C or higher.

摘要： PURPOSE:To obtain an electrochromic display device which provides a uniform display by performing a heat treatment while bringing the entire back surface of an ITO glass substrate into surface contact with the flat part of a mount base made of metal. CONSTITUTION:The ITO glass substrate 2 formed by an ion plating method is heat-treated under conditions of 10 Torr in degree of vacuum and 450 deg.C for 3hr. This heat treatment is carried out while the entire back surface 20 of the ITO glass substrate 2 is brought into surface contact with the flat part 10 of the mount base 1 (with 2mm thickness) made of stainless steel so that at least part of the surface is made into the flat part 10. The IT glass substrate 2 is heated and cooled more uniformly in the heat treatment. Consequently, the temperature distribution at the time of the heat treatment of the ITO glass substrate 2 is as uniform as possible and the uniformity of the ITO film 21 of the ITO glass substrate 2 is improved, thereby reducing variance in the electronic resistance of an ITO film 21 with the position.

摘要： PURPOSE:To make mounting of lead wires easy and to increase mechanical strength of an electrode by forming a projection in each of the first sheet-like current collector made of conductive material and the second sheet-like current collector made of aluminum, and alternately stacking them, then connecting the projecting pieces with a belt-like corrugate lead plate. CONSTITUTION:The first 0.4mm thick current collector 10a and the second 0.4mm thick current collector 10b are formed with an aluminum sheet. Projections 2a, 2b are formed at their each end. The first and the second current collectors 10a and 10b are immersed in a solution except for their projections 2a, 2b, then they are electrolyzed to obtain the first current collector 10a on which polypyrrole 3 is formed and the second current collector 10b on which lithium is formed. They are stacked with a separator S made of polypropylene interposed so that projections 2a, 2b are alternately located. A belt-like currugated lead plate 4 is fixed to each group of projections 2a and 2b. Each of the lead plate 4 is connected onto a positive side and a negative side of a voltage supply source. By connecting with the corrugated lead plate, a lead wire mounting job is made easy, and press-fixing of the current collector is made elastic and strong.

摘要： PURPOSE:To uniform the thickness of a formed thin film by arranging a low- resistance material at the external edge part of a positive electrode and supplying a current uniformly from the outer peripheral side of the positive electrode. CONSTITUTION:The conductive material 14 which has lower resistance than the positive electrode 10 is stuck previously on the external edge part of the positive electrode 10 and dipped in electrolyte while covered with a mask material 16 which has corrosion resistance to the electrolyte, and a voltage is applied between both positive and negative electrodes. Therefore, the current supplied from a lead wire 18 to the positive electrode 10 flows to the center of the positive electrode 10 from the conductive material 14, so extremely uniform current density is obtained on the whole of the positive electrode 10. Consequently, the thickness of the thin film formed on the surface of the positive electrode 10 can be made uniform.
