    • The present invention relates to a meter suitable for use in vehicles. The meter has a polarizing window which allows light having a vertical component only to pass therethrough and is preferably oriented so that optimum angle of incidence i of the polarized light on, the windshield for example, for attenuation of the reflection thereof, occurs. The outer surface of the window is preferably provided with a non-reflecting or anti-glare finish so that light from a source external of the meter is not reflected off the window. The arrangement ensures that visibility obscuring reflections on the windshield and the like caused by the meter mounted in prominent position on the instrument panel is not caused by light sources within or external of the meter.
    • 本发明涉及一种适用于车辆的仪表。 仪表具有偏振窗,其允许具有垂直分量的光仅通过其中,并且优选地定向成使得出现偏振光(例如挡风玻璃)的最佳入射角i,用于衰减其反射。 窗口的外表面优选地设置有非反射或防眩光光洁度,使得来自仪表外部的光源的光不会从窗口反射。 该装置确保了由安装在仪表板上的突出位置的仪表引起的挡风玻璃等上的反射的可视性不会由仪表内部或外部的光源引起。

    • An electrophotographic apparatus for forming or printing any desired number of copies of a document from the same and single electrostatic charge latent image comprisinga photosensitive member such as a photoconductive drum which is rotated at a constant velocity;a corona charger for uniformly charging the photosensitive drum;a document feeding device for advancing the document through an exposure-scanning portion at a constant speed;an optical device for projecting an image of the document at the exposure-scanning portion onto the drum to form an electrostatic charge latent image thereon;a developing device for developing the latent image with toner particles to form a toner image;a transferring device for transferring the toner image onto a record paper;a fixing device for fixing the toner image on the record paper to form a final copy;a clock pulse generator for producing clock pulses in synchronism with the rotation of the photosensitive drum;master and slave timing pulse generators for receiving the clock pulses to produce timing pulses;means for detecting the document at the document feeding means to produce a document detection signal;means for setting the desired copy number to be formed to produce a copy number signal; anda control device for receiving the timing pulses, the document detection signal, and the copy number signal to produce control signals necessary for controlling the operation of the various devices of the apparatus. Duplicating operation for forming a single copy is divided into two portions each of which is assigned to the master and slave timing pulse generators, respectively, whereby during the duplication for the last copy of the desired number of copies under the control of the slave timing pulse generator, a new duplication for a next document can be initiated under the control of the master timing pulse generator which produces timing pulses necessary for duplication during one rotation of the photosensitive drum.

    • A vibration detection apparatus for, for example, ultrasound/AE, with Fiber Bragg Grating (FBG), is used for elastic wave detection generated by a material impact and ultrasonic defect detection. Disadvantageously, the apparatus cannot detect ultrasound and has degraded performance at variable temperatures and strains. In response, a highly sensitive, small and light vibration detection apparatus is provided. FBG reflection light is lased by using a fiber laser. The intensity of the lased reflection light from the FBG is converted into an electrical signal. Thus, the ultrasound vibration or the like is detected. A vibration detection system includes an optical amplifier 42, an optical circulator 43, and an optical coupler 45. An FBG 44 and an entry/exit port of the optical circulator are connected by an optical fiber. The optical coupler and the optical amplifier are inserted between an entry port and an exit port of the optical circulator. The entry port and the exit port are connected by an optical fiber.
