    Abstract: A cathode ray tube having an optical filter disposed between the face panel of the cathode ray tube and a safety glass plate for preventing external light from being passed therethrough to the face panel and transparent resin injected between the face panel and the safety glass plate to secure the safety glass plate and the optical filter to the cathode ray tube in front of the face panel thereof. The optical filter is composed of a laminated element composed of alternate transparent layers and dark layers, the direction of extension of the laminations being substantially parallel to the face panel of the tube, i.e., with the contacting faces of each layer of the laminations being at right angles to the face panel or at a substantial angle thereto.

    Abstract: A UHF-VHF combination tuner is provided with a rotatable turret having a plurality of tuning segments for receiving VHF and UHF signals, respectively, which are sequentially arranged around the turret for being selectively disposed at an operative position. Each tuning segment for the VHF signal includes at least an oscillating coil which, when the respective segment is at the operative position, forms part of a local oscillator provided for conversion of the respective VHF signal to an IF signal. Each tuning segment for the UHF signal includes a potentiometer which, when the respective segment is at the operative position, controls a variable reactance element of a local oscillator provided for conversion of the respective UHF signal to an IF signal. Further, the tuning segments have rotatable pinions by which the inductance of the oscillating coil or the voltage dividing ratio of the potentiometer may be varied, as the case may be, and a fine tuning device is provided with a drive gear adjacent the operative position for driving engagement with the pinion of the tuning segment selectively disposed at the operative position.
