Title: Automatic weighing device for powder and grain substance
Inventor: NAKAYAMA KAZUMASA
IPC: G01G13/04
Filed: 1978-10-12
Abstract: PURPOSE: To eliminate the effect due to the fluctuation of the supplied pressure to the pressure gas or the density change of the powder and grain substances by controlling the flow amount of the pressure gas to be supplied to the pressure room and thus controlling the filling amount of the powder and grain substances, thus increasing the filling accuracy.  
     CONSTITUTION: The weight of bag 5 which varies by the laps of time is detected at weight detection part 4 after the filling of the powder and grain substances is started to bag 5. The signal obtained at part 4 is supplied to weight controller 6 to be compared with the value corresponding to the lead-out amount of the powder and grain substances which is set previously at controller 6 and per the unit time. In case some difference is detected between the both value, the opening degree of valve 5V is controlled to secure the equal value. Thus the amount of the air to be supplied to pressure room 3 from valve 4V can be controlled. When part 4 detects the fact that the filled amount reaches the prescribed level, valve 3V is closed to cut off the lead-out of the powder and grain substances. As a result, the filling accuracy can be increased.

Title: Liquid crystal nonglaring mirror
Inventor: SATO KAZUHIRO
IPC: G02F1/13
Filed: 1991-04-26
Abstract: PURPOSE:To obtain the bright nonglaring mirror which uses no polarizing plate by providing a liquid crystal cell wherein liquid crystal is dispersed and held in a matrix. CONSTITUTION:A liquid crystal cell 3 is provided on the front surface of a reflecting mirror 2 and held between transparent conductive sheets from before and behind. Namely, while no voltage is applied between the conductive sheets, a liquid crystal 5 is oriented along the wall of a capsule and incident light is scattered by the surface of the capsule and in the capsule, so the light transmissivity is small. In a voltage ON state, on the other hand, the long axis of the liquid crystal 5 is oriented at right angles to the conductive sheets and the incident light is not scattered, but travels straight, so that light transmissivity becomes maximum. Therefore, when the mirror is used in daytime when glaring prevention is not necessary, the voltage ON state is set between the conductive sheets and the incident light travels straight and is reflected by the reflecting mirror 2, thereby obtaining a glaring state wherein an image is bright. In nighttime when the glaring prevention is necessary, the voltage OFF state is set between the conductive sheets and the reflection factor of the reflecting mirror 2 decreases, thereby obtaining a nonglaring state wherein the image becomes dark.
