An input screen of an X-ray fluoromultiplier tube, that is, an X-ray image intensifier tube, wherein an evaporated aluminum film is interposed between a substrate and a fluorescent substance (cesium iodide) film is disclosed. The input screen according to this invention does not undergo the 'charge-up' attributed to the exfoliation or cracks of the cesium iodide film, and can therefore present a picture of extraordinarily high quality.

Input screen

A high voltage generator suitably applied to the television receiver has a secondary winding divided into three or more units of different numbers of turns by a plurality of diodes. Each secondary winding unit has a different distance from the primary winding, so that the winding units are tuned to different high harmonics of the fifth or higher resonance orders, or some of the winding units to the same harmonic of fifth or high order and the remaining to harmonics.

Apparatus for generating high voltage for cathode-ray tube

A high voltage rectifier arrangement for producing a D.C. high voltage necessary for the cathode-ray tube in a television receiver in which a voltage multiplier rectifier composed of a plurality of rectifiers and high voltage condensers is molded with a resin in an insulator case, the input terminal which is to be led out of the insulator case is fixed with a piece formed of a material having good adherence to the molding material, and the led out input terminal and the junction part of the led out input terminal and the lead wire of a flyback transformer are covered with an insulating rubber cap pressed around the piece.
