Title: Surface acoustic wave filter
Inventor: YAMAMOTO TAIJI
IPC: H03H9/145
Filed: 1990-03-28
Abstract: PURPOSE:To realize a high performance filter with low in-band amplitude ripple and delay ripple by tilting ends of a dummy pattern of split electrodes adjacent to interdigital electrodes on a propagation path of a surface acoustic wave and connecting to ground tilted in the propagation path of the surface acoustic wave. CONSTITUTION:A dummy pattern 12 is arranged adjacent to interdigital electrodes 11 at a prescribed electrode pitch and the other ends of the dummy pattern 12 connecting to ground are tilted in the propagation direction of the, surface acoustic wave. Since the ends of the electrode fingers of the tilted part are formed rectangular, the production of a reflecting wave is suppressed by giving a gentle slope to the ends. Thus, the in-band amplitude ripple and delay ripple in the filter characteristic are reduced and a high performance filter is realized.

Filed: 1980-06-12
Abstract: PURPOSE:To reduce the internal resistance, and enhance both the diacharge characteristics and the preservation characteristics of an alkaline battery by placing a semidried separator on a positive electrode consisting of silver oxide and a given amount of manganese dioxide. CONSTITUTION:A metal exterior case 1 is packed with a positive molded body 2, which consists of silver oxide and 5-50wt% of manganese dioxide. A semidried separator 3 which is left to stand in an air-conditioned atmosphere is placed on the body 2, before a liquid holding material 4 made of nonwoven cloth, and a gel-like negative electrode 5 are placed over the separator 3, thereby a battery being constituted. The separator 3 is prepared by, for example, laminating cellophanes on  both sides of a micro-porous polyethylene film. The separator 3 preferably contains 0.05-0.5wt% of water. The positive molded body made of silver oxide added with manganese dioxide, when its brittleness causes any cut or the like in it, is not damaged owing to the elasticity of the separator 3. Besides, the hydrophilic property of the separator 3 reduces the internal resistance. Consequently, the discharge characteristics and the preservation characteristics of the battery can be enhanced.

Title: Three-electrode type pickup tube
Inventor: MIYAZAWA TSUTOMU
IPC: H01J29/45
Filed: 1979-06-26
Abstract: PURPOSE:To reduce interelectrode electrostatic capacity and lessen color cross-talk by providing a transparent electrode whose both sides are provided with glass between a tri-color filter and each color-signal output electrode and then earthing the transparent electrode. CONSTITUTION:The transparent electrode 7 is provided through the glasses 5 and 6 between the filter 2 and the electrode 3 and then earthed. The capacity between the electrode 3 and the earth is increased but the electrostatic capacity through the glasses, among the interelectrode electrostatic capacity, is decreased. Accordingly, the interelectrode electrostatic capacity is relatively decreased. The electrostatic capacity between the electrode 3 and the earthed transparent electrode 7 exerts an influence on the signal of brightness, but because the capacity is determined by the interelectrode distance and the dielectric constants of the glasses 5 and 6 holding the distance, it can be controlled to an allowable value.
