    摘要: By inserting a rectangular conductive flat member having uninterrupted straight edges into a waveguide in contact relation of their edge portions to the waveguide walls in parallel with an electric field therein, cut-off frequencies at portions of the waveguide to which the conductive flat member is inserted become higher to form a cut-off region. The conductive flat member is composed of a conductor plate or by evaporating a conductive thick film on a dielectric or magnetic plate. The conductive flat member occasionally lined with a non-conductive flat member is provided with circuit elements such as slots formed by punching and strip lines or semiconductor diodes formed by evaporation, and microwave circuits having various functions such as filter circuits, directional couplers, oscillator circuits, frequency converter circuits, frequency multiplier circuits, switch circuits, phase shifter circuits, etc. are constructed on the conductive flat member by combination of the circuit elements through mutual coupling therebetween. These microwave circuits are coupled to transmission regions of the waveguide adjoining both sides of the cut-off region by circuit elements located at the end portion of the conductive flat member. Accordingly, only by inserting into the waveguide a conductive flat member on which various circuit elements are provided, desired microwave circuits of various kinds are constructed very easily inside the waveguide. Such microwave circuits are small in size and low in transmission loss due to elimination of waveguide converters conventionally used, and are suitable for massproduction due to simplicity of structure and ease of manufacturing and assembling which result from mechanical working technique of high degree being unnecessary.

    摘要: A method for efficient production of a welding solid wire free of copper plating. The method consists of drawing by means of roller dies with the help of a dry solid lubricant for drawing which is at least either of sodium stearate or potassium stearate, removing the lubricant from the wire surface by means of a washing device, and applying a lubricant for wire feeding to the surface of the drawn wire by means of an oiling device. High-speed drawing by means of roller dies makes a stock wire into a welding solid wire having the diameter of the finished wire or nearly finished wire. The drawing step is followed by the washing step and the lubricant applying step, which are all accomplished in-line.
