Pressure test device for cathode-ray tube
专利汇可以提供Pressure test device for cathode-ray tube专利检索，专利查询，专利分析的服务。并且PURPOSE:To enable testing without suspending the transport of cathode-ray tubes by enabling stray-emission test on the cathode-ray tube being moved on a conveyer at a certain speed. CONSTITUTION:The device has an opening 111 through which a faceplate 11 of the cathode-ray tube placed upside down is exposed to outside at its center area. A hanger assembly 14 consisting of a holder 11 with a pad 12 surrounding the opening 111 and an arm 13 is suspended from a conveyer 15 by means of a hang wire 14, so that the hanger assembly is movable at a right angle to the plane of this paper at a certain speed. A rack 21 is movable on a rail 24 by means of a positioning device 23 installed at the top 22 and is equipped with an arm 27 having a measuring unit 26 with a built-in photo-receiving sensor 25 engageable with the face plate 11. On the rack 21, predetermined test voltates are supplied to the stem 12 of the cathode-ray tube 1 and its anode terminal 13 and power supply to the power unit supplying the photo-receiving sensor 25 with power is obtained from a slide element slidable on a rail-formed power line 29.，下面是Pressure test device for cathode-ray tube专利的具体信息内容。
