Title: Development device
Inventor: IZUMIZAKI MASAMI
IPC: G03G15/08
Filed: 1990-10-04
Abstract: PURPOSE:To prevent a developer, etc., from sticking on a detection window member and to prevent an ATR signal from being misdetected by providing a vibration application means which applies vibration to a developer concn. detection and controller (ATR) detection window member at specific timing. CONSTITUTION:When a latent image on an image carrier 4 is developed for visualization, a developing sleeve 3 is applied with an AC vibrating electric field and a DC bias by a power source 15 and toner sticks on the image carrier 4 from the developing sleeve 3. After the development ends, the ATR detection window member 17 is vibrated with an ultrasonic wave of 50V and 50 kHz from an ultrasonic vibrator 16 at timing where an ATR signal is not detected to propagate a progressive wave inward from the front. Thus, the ATR detection window member 17 is vibrated with the ultrasonic wave to prevent toner, etc., from sticking on the window member 17. Consequently, the ATR signal is prevented from being misdetected.

Title: Light guide for photosensor and its manufacture
Inventor: MATSUMOTO HIDETOSHI
IPC: G02B6/10
Filed: 1988-10-25
Abstract: PURPOSE:To enlarge the outgoing extent of lighting light and incoming extent of signal light and, at the same time, to reduce the outgoing extent of the signal light so that the signal light can be fetched easily by forming a light guide for photosensor to a tapered body, with the diameter of one end being smaller than that of the other end. CONSTITUTION:A light guide 1 for photosensor is formed to a tapered body by making one end smaller than the other end in diameter. Lighting light made incident on the thicker end is emitted from the thinner end after the light is propagated through the guide 1. When the diameters of the larger and smaller ends are respectively represented by d1 and d2, the emissive extent (emissive angle) at the emissive end of the light light becomes d1/d2 (>1) times as large as that of a columnar light guide 1 from the principle of a tapered fiber and the lighting light can irradiate widely until the light reaches an optical fiber 4 for detecting signal light. Therefore, signal light can be led to the photosensor effectively, since the outgoing extent of the lighting light can be enlarged and the outgoing extent of the signal light can be reduced.

Title: Shield plate for forming metal film of cathode-ray tube
Inventor: DEGUCHI TATSUYA
IPC: H01J29/02
Filed: 1992-09-11
Abstract: PURPOSE:To decrease improper withstand voltage including discharge by reducing a shield amount at the time of forming a metal back, and lowering the separation of a black non-luminous material or the like from the inner surface of a panel. CONSTITUTION:The end 21a of a shield plate 21 used for the vacuum deposition of an aluminum film 14 on the inner surface of a panel 11 has convex curved surface relative to a pin 17 for supporting a color screening mechanism. In addition, the plate 21 is bent in such a way as keeping the end 21a near the pin 17. As the shield plate 21 is bent in that way, a shield amount can be reduced to sufficiently cover carbon 13 or the like. On the other hand, the shield plate 21 is bent, but the end 21a thereof is curved. Thus, even when the body of the panel 11 or the like comes in contact with the shield plate 21 at the time of mounting the panel 11 on a deposition furnace, the panel 11 easily slides along the end 21a and is hardly stranded on the shield plate 21.
