    • A simulated gun for use with a disk-shaped or substantially disk-shaped flying member made of a metal as a bullet for discharging it forward, the simulated gun comprising: a gunbarrel having the hollow whose cross section along a direction normal to a flying direction of the flying member is vertically long and has vertical and horizontal dimensions set substantially equal to the diameter and the thickness of the flying member, respectively, and a flying member hitting position being set at the inner back position of the gunbarrel; a hammer provided at the inner back position of the gunbarrel, reciprocatingly movable between an advanced position where it hits the rear part of the flying member set at the flying member hitting position and a retracted position which is located in a rearward from the advance position, and adapted to hit the flying member set at the flying member hitting position, and a trigger for reciprocatingly moving the hammer.
    • 一种模拟枪,用于由金属制成的圆盘状或大致圆盘形的飞行构件,用于将其向前排放,该模拟枪包括:枪管,其具有沿垂直于飞行方向的方向的横截面 飞行构件的垂直和水平尺寸分别基本上等于飞行构件的直径和厚度,并且飞行构件击打位置设置在枪管的内部后部位置; 设置在枪管的内后位置的锤,能够在其位于飞行构件击打位置处的飞行构件的后部的前进位置与位于从前进位置向后方的缩回位置之间往复运动, 并且适于撞击设置在飞行构件击打位置处的飞行构件,以及用于使锤子往复运动的扳机。

    • A microwave transmitting and receiving apparatus comprises a Gunn diode as an oscillating element and a mixer diode as a receiving element disposed within a rectangular waveguide closed at one end by its short-circuiting plate. The oscillating and receiving elements are juxtaposed with each other at a position spaced by 1/2 .lambda.g (.lambda.g: wavelength in the waveguide) from the short-circuiting plate toward an opening of the waveguide. An adjusting screw for permitting a match of the receiving element impedance with the input signal impedance and for adjusting the output power is fitted by screw engagement to the waveguide at a position spaced by 1/4 .lambda.g from a straight line connecting the both elements toward the waveguide opening, and another adjusting screw for oscillating frequency-adjustment is fitted by screw engagement to the waveguide at a position between said straight line and the short-circuiting plate.
    • 微波发射和接收装置包括作为振荡元件的耿氏二极管和作为接收元件的混合二极管,该接收元件设置在其一端由其短路板封闭的矩形波导内。 振荡和接收元件在从短路板朝向波导的开口隔开1/2λg(波导中的λg:波长)的位置处彼此并置。 用于允许接收元件阻抗与输入信号阻抗匹配并用于调节输出功率的调节螺钉通过螺旋接合装配在与连接两个元件的直线相距1/4λg的位置处的波导 波导开口和用于振荡频率调节的另一个调节螺钉通过在所述直线和短路板之间的位置通过螺旋接合装配到波导。
