Abstract: PURPOSE:To thoroughly eliminate the deterioration of a counter electrode and to make a titled plate adaptable to applications such as filters as well by providing a thin Prussian blue layer on the surface of the transparent electron conductive layer of a working counter electrode and subjecting the thin layer to anodic oxidation. CONSTITUTION:In2O3 is deposited by evaporation on a transparent base body 9 to form the transparent electron conductive layer 8 and a transparent coloring and decoloring layer 7 is deposited by evaporation on a working electrode 2 by using WO3 as an essential component. A transparent active material layer 6 formed by subjecting the insoluble Prussian blue of which the essential component has the structure expressed by the formula to the anodic oxidation is provided on the working counter electrode 1 and is united to a packing 5 via an electrolyte 4.

Title: Solid electrolytic capacitor
Inventor: MORIMOTO TAKESHI
IPC: H01G9/028
Filed: 1989-02-07
Abstract: PURPOSE:To reduce leak current by a method wherein, in a capacitor in which conductive polymer compound is used as solid electrolyte, a specified amount of water is made to exist in the inside of the capacitor. CONSTITUTION:Methods to make water exist in a capacitor are as follows; the one is that, for example, in the case where highly conductive polymer compound is formed in aqueous liquid, the compound is encapsulated and sealed in a case under the state where very small amount of water content is contained by controlling the drying condition, and the other one is that a specified amount of water is added in the case and sealed after the compound is sufficiently dried. The amount of coexisting water is desirable to be 10-500mug. In the part where leak current generates at the time of applying a voltage, it is considered that a dielectric oxide film is damaged and a metal surface is exposed. When a suitable amount of water content exist there, it is considered that the exposed metal surface is electrochemically oxidized and reacts with water molecule to form a rigid oxide coating film. Hence the leak current can be reduced.

Abstract: PURPOSE: To prevent print failure due to weak power source by judging whether a DC power source is from a battery or an AC adapter based on the output voltage change state of the DC power source for a predetermined period immediately after the end of the predetermined operation of a printing mechanism. CONSTITUTION: When a stamp forming unit is executed, a power source 150 has an AC adapter 151 for stepping down and rectifying an external AC power and a battery 105. If a CPU 111 reads the power source voltage so that it is a battery weak decision voltage or less at the time of printing, a weak battery flag is turned ON. If the weak battery flag is ON after the end of the origin reset operation after the print is ended, a converging voltage is decided according to the voltage read without a predetermined time from the time of ending the origin resetting. Then, the adapter decision voltage is decided from the converging voltage, and the number of the adapter decision voltage or more of the voltage read without the predetermined time is calculated. If the number is a predetermined number or less, the effect of weak battery state is displayed on a liquid crystal display.
