    • A field-emission type switching device includes a substrate formed with a recess having a straight edge and serrated edge opposite to the straight edge. A gate electrode is formed at the bottom of the recess. An emitter electrode is provided over the substrate and formed with a serrated edge which is slightly off alignment with the serrate edge of the recess so as to provide an emitter overhanging portion overhanging the recess. Similarly, a collector electrode is provided over the substrate means and formed with a straight edge which is slightly off alignment with the straight edge of the recess so as to provide a collector overhanging portion overhanging the recess. The emitter and collector electrodes are disposed in one plate and the gate electrode is disposed in another plane below the one plane.
    • 场发射型切换装置包括形成有具有与直边相反的直边缘和锯齿状边缘的凹部的基板。 栅电极形成在凹部的底部。 发射电极设置在衬底上并且形成有锯齿形边缘,该锯齿形边缘与凹槽的锯齿形边缘稍微偏离对准,以便提供突出于凹部的发射体悬伸部分。 类似地,集电极设置在衬底装置上方并且形成有直线边缘,其与凹部的直边稍微偏离对准,以提供突出于凹部的收集器悬伸部分。 发射极和集电极设置在一个板中,栅电极设置在一个平面下方的另一个平面中。

    • An optically sensing device is made up of the sensor materials that cause the value of birefringence to vary itself in accordance with external physical volume; a polarizer and an element provided with two total reflection surfaces causing the beam path to invert its direction by an angle of 180.degree.. The optically sensing device has the capability of setting the phase bias by applying the two total reflection surfaces causing the beam path to invert its direction by an angle of 180.degree.. Since each element has different functions, one functioning as a mirror and the other as a quarterwave plate, the optically sensing device is of extremely simple structure and is compact. In addition, since the optically sensing device provides a constant phase bias unlike the unstable performances of conventional quarterwave plates, it guarantees high-precision performance. Also, the use of inexpensive elements ensures reduced cost. In particular, by effectively combining such selected materials featuring photoelastic and electro-optic effects, the optically sensing device embodied by the present invention is extremely effective for detecting the physical volume of a wide variety of substances.
    • 光传感器件由传感器材料组成,导致双折射值根据外部物理体积自身变化; 偏振器和设置有两个全反射表面的元件,使得光束路径将其方向反转180度的角度。 光学传感器件具有通过施加两个全反射面来设定相位偏置的能力,使得光束路径将其方向反转180度的角度。 由于每个元件具有不同的功能,一个用作反射镜,另一个用作四分之一波片,因此光学传感器件的结构非常简单且紧凑。 此外,由于光传感器件提供与常规四分之一波片不稳定性能不同的恒定相位偏移,因此保证了高精度的性能。 此外,使用便宜的元件确保降低成本。 特别地,通过有效地组合具有光弹性和电光效应的所选材料,本发明实施的光学传感装置对于检测各种物质的体积是非常有效的。

    • A camera shutter mechanism for opening and closing a shutter aperture to effect an exposure comprises a group of opening blades movable, when released, from a closed position covering the shutter aperture to an open position uncovering the shutter aperture to thereby initiate an exposure, and a group of closing blades movable, when released, from an open position uncovering the shutter aperture to a closed position covering the shutter aperture to thereby terminate the exposure. A release mechanism releases the opening blades thereby enabling them to move to the open position for initiating the exposure, and subsequently releases the closing blades thereby enabling them to move to the closed position for terminating the exposure. A driving member automatically operates immediately after completion of the exposure to move the group of opening blades back towards the closed position so that the aperture is at least partially covered thereby so as to improve the light-shielding capability of the shutter mechanism.
