    • A method of preparing light-sensitive silver halide grains by the simultaneous addition of two or more aqueous solutions of inorganic salts in the presence of a protective colloid, in which the production of silver halide nuclei is brought to completion during the initial stages of grain formation and the concentrations of the aqueous solutions of inorganic salts reacting with one another are increased to such an extent that fresh nuclei of crystal grains are hardly produced during the period of grain growth. The process provides grains having a desired size, for which there exists a narrow size distribution, in a relatively short period of time and which avoids any abrupt increase in the flow rates of aqueous solutions of inorganic salts added to a reaction vessel during the final stage of grain growth.
    • 通过在保护胶体的存在下同时加入两种或更多种无机盐水溶液来制备感光卤化银颗粒的方法,其中在晶粒形成的初始阶段使卤化银核的产生完成 并且使无机盐的水溶液的浓度相互反应增加到在晶粒生长期间难以产生晶粒的新鲜核的程度。 该方法在相对短的时间内提供具有所需尺寸的颗粒,其具有窄尺寸分布,并且避免了在最终阶段加入到反应容器中的无机盐的水溶液的流速的任何突然增加 的粮食增长。

    • A tuning circuit comprises a pair of identical resonant circuits each including a transmission line and a capacitive element, a coupling circuit associated with each transmission line to inject microwave energy into the resonant circuits and extract the tuned energy therefrom. An image trapping circuit is included which comprises a first section which intersects one of the transmission lines and connected to the coupling circuit associated with the intersected transmission line and a second section which extends from the point of connection of the first section with that coupling element to the opposite transmission line in a direction skewed relative to each transmission line. The second section of the image trap circuit provides a smooth interstage coupling between the two transmission lines over a range of resonant frequencies.
