Abstract: PURPOSE:To prevent ejection of a second droplet or taking-in of a bubble from occurring, by rapidly expanding an electro-mechanical converting element, maintaining the element in the expanded state for a predetermined time, then rapidly contracting the element, maintaining the element in the contracted state for a predetermined time, then rapidly expanding the element in an amount corresponding to the temperature of an ink, and gradually returning the element to an initial state. CONSTITUTION:An electro-mechanical converting element 11 is rapidly expanded by a rapid voltage drop, and the expanded state is maintained. The element 11 is then rapidly contracted by a rapid voltage rise, and the contracted state is maintained for a period of time of 2(l1+2l2)/c, wherein l1 is the distance from the element 11 to the tip of a jet nozzle, l2 is the distance from the element 11 to an ink-supplying port, and c is the propagation velocity of a pressure wave in a glass tube 22.

Abstract: PURPOSE:To improve conversion efficiency to a voice signal from an electric signal and to facilitate the production of diaphragm by consisting essentially of the fibrous inorganic compound of which fibrous diameter is <=100 micron and of which fibrous length is above tenfold of the fibrous diameter and forming a diaphragm with a paper adding binder containing a superfine fiber as a base material to said main component. CONSTITUTION:As the main component of the inorganic paper, the whickers such as magnesia, alumina or graphite or the inorganic compound in the fibrous state which is made by cutting these fiber into several millimeter is used. The paper is made by adding the superfined fiber of which percentage for the main component is 0.5-10 weight % to the main component. The diaphragm obtained as the base material in this way has heat-resistance for >=1000 deg.C in the case of using the inorganic paper 1 of alumina group for example as the base material. Though the density of the alumina fiber in itself is 3.4g/cm<2>, the density of the inorganic paper 1 becomes 0.29g/cm<2> because it contains air in the process of the paper making. Therefore the high conversion efficiency to the voice signal from the electric signal can be obtained.

Title: Silver oxide battery
Inventor: ASADA AKIRA
IPC: H01M4/54
Filed: 1980-08-09
Abstract: PURPOSE:To prevent any increase in the internal resistance of a silver oxide battery caused during the preservation by pressing a positive electrode body, which is prepared by forming an argentous oxide layer and a silver layer over the periphery of a silver oxide layer by reduction, so as to make the porosity of the silver layer to be decreased. CONSTITUTION:A positive electrode body 1 prepared by forming an argentous oxide layer 3 and a silver layer 4 over the periphery of a silver oxide layer 2 through reduction, is pressed so as to make the porosity of the silver layer 3 to be reduced. Here, the pressure applied to the body 1 is preferred to be about the same as that used in forming a silver oxide molded body, for example, 3-10t/cm<2>. The silver layer 4 obtained by reducing argentous oxide has a porosity of about 12vol%, which is higher than that of a layer obtained by subjecting silver powder to pressure molding, and the porosity of the former silver layer 4 is reduced through pressing to about 2vol%, which is the same porosity as that of the layer obtained by subjecting silver powder to pressure molding. Owing to the above constitution, the disappearance of the silver layer by reoxidation is diminished since electrolyte touches and diffuses into the silver layer 4 to a smaller extent. Consequently, any increase in the internal resistance caused during the preservation can be prevented.
