摘要： An electric steering apparatus which effects position adjustment by electric drive has a screw shaft parallel to upper and lower columns. A nut member rotatably supported by a housing fixed to a bracket is fixed against movement in the axial direction of the screw shaft and threadably engaged with a screw portion provided at one end of the screw shaft. In a preferred embodiments, the other end of the screw shaft is pivotally connected to the upper column for pivotal movement relative to the bracket in the direction of tilt, the nut member is self-aligning in the housing, and the nut member is rotatively driven by an electric motor to move the screw shaft in the axial direction and thereby move the upper column, whereby position adjustment can be accomplished. The apparatus is provided with a back-lash preventing device in which the screw shaft is pressed against the nut member in a radial direction and the threadably engaged portions of the screw shaft and the nut member are urged against each other.

摘要： A faceplate structure of a multi-color image pickup tube has a light transmitting thin glass plate, to which are bonded a rectangular color separating filter base plate deposited with a color separating stripe filter at the center of one surface of the thin glass plate with the color separating stripe filter opposing the thin glass plate, and a collar plate having a rectangular through hole for receiving therein the color separating filter base plate. On the other surface of the light transmitting thin glass plate are successively deposited a transparent electroconductive film and a photoconductive film. The faceplate structure is airtightly secured to one open end of an envelope of the image pickup tube with its other surface opposing the inside of the envelope.
