Title: Silver oxide battery and manufacturing method therefor
Inventor: KISHI IWAO
IPC: H01M4/54
Filed: 1993-07-13
Abstract: PURPOSE:To detect with non destruction a battery with an increased interval discharge through measurement of the open circuit voltage, by adding to the positive-electrode portion a bi-valent silver oxide of which the weight is not over 1% to the zinc weight of the negative-electrode portion. CONSTITUTION:A bi-valent silver oxide of which the weight is not over 1% to the weight of the zinc in the negative electrode is formed in the positive electrode. By charging the amount of electricity corresponding thereto, the battery voltage is increased to make possible the detection of the succeeding battery interval discharge with non destruction. Further, after detection of the abnormal battery with an internal discharge, by aging, partial discharge processing, etc., it is possible to eliminate the shortcomings of high voltage. That is, although since the positive electrode contains therein a bi-valent silver oxide, the open circuit voltage is high, the battery with interval discharge can be detected by measuring the open circuit voltage because the contact of the bi-valent silver oxide is very small and this bi-valent silver oxide is consumed according to the interval discharge if any, into silver oxide which results in that the voltage decreases in level. By adding to the positive electrode portion the bi-valent silver oxide of which the weight is from 0.02% to 1% to the zinc weight in the negative electrode as mentioned above, the battery with a large internal discharge can be detected with non destruction through the measurement of the open circuit voltage.

IPC: G11B5/012
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic storing medium/system including a keeper layer made of a soft magnetic material of comparatively y low permeability arranged on the magnetic storing layer or between the layers. SOLUTION: A keeper layer 36 of low permeability is arranged either the upper part or the lower part of a magnetic storing layer 34. Under the non- saturated condition, the keeper functions as a branching path for magnetic flux outputted from the transition recorded on the magnetic storing layer 34 and the magnetic field of the transition image recorded in the keeper is formed. The branching path prevents the signal of magnetic flux outputted from the recorded transition from reaching a head. For reading out data from the transition recorded on the magnetic storing layer 34, a bias current is applied on the coil of the head and biased magnetic flux for saturating a part of the keeper layer 36 is generated. When the layer is saturated, the keeper does not branch the magnetic flux generated form the recorded transition in an area shown by a head reproducing transducer.

Filed: 1986-07-24
Abstract: PURPOSE:To obtain the titled element having less tendency for generating a hydrogen gas by making larger amount of a polyaniline coating forming the electrochromic (EC) layer on a counter electrode than the amount of the polyaniline coating forming the EC layer on a working electrode. CONSTITUTION:The EC layer 7 is formed on an indium-tinoxide (ITO) layer 3 for the working electrode. The EC layer 7 is a thin film composed of a polyaniline having an excellent EC characteristics and obtd. by electrolytic oxidation polymerizing aniline monomer. The coating amount C1 of polyaniline forming the EC layer 7 is equal to or more than the coating amount C2 of polyaniline forming the EC layer 4 of the working electrode side. Thus, the coating amount of polyaniline (C1 or C2) is propertional to quantity of electricity of an electric charge which takes part in the oxidation-reduction reaction generated at the time of impressing a prescribed voltage between the both electrodes. Thus, the generation of bubbles of the hydrogen gas, etc., near to the EC layer mounted on the counter electrode is prevented, because generation of surplus amount of the electric charge is prevented.

IPC: H01G9/04
Filed: 1989-07-05
Abstract: PURPOSE:To improve yield in manufacture without causing defective leakage currents by applying constant voltage for a fixed time during a process in which a capacitor element with an anode body element, to which a solid electrolytic layer composed of a conductive high molecule is formed, is sheathed by a resin for sheathing. CONSTITUTION:A capacitor element 10 is coated with a thermo-setting epoxy resin as a resin for sheathing through dipping, constant voltage is applied between an anode leader 2 and a cathode lead 9, the capacitor element 10 is introduced into a resin curing furnace, and aging treatment is executed while the capacitor element 10 is cured. That is, since a process in which constant voltage is applied for a fixed time is provided in a sheathing process, aging treatment simultaneously progresses in the process of curing the resin. Restoration progresses during the time of the small damage of a dielectric oxide film generated due to mechanical stress at the time of resin curing, thus preventing the elevation of the level of leakage currents. Accordingly, defective leakage currents in a resin sheathing process is reduced, thus decreasing manhours.
