    摘要: Eine gesteuerte Kapazität oder Induktivität wird über einen ON/OFF Signal gesteuerten Schalter an einen Schwingkreis gekoppelt, wobei das resultierende Kopplungsintervall ein Teilintervall der Schwingkreisperiode umfasst. Eine erste Zustandsänderung des ON/OFF Signals reagiert auf eine Steuergrösse, welche die Resonanzfrequenz, Scheinwiderstand oder Scheinleitwert des Schwingkreises steuert und eine zweite Zustandsänderung des ON/OFF Signals, welche der ersten Zustandsänderung des ON/OFF Signals entgegengesetzt ist, reagiert auf eine Zustandsänderung des Schalters. Dadurch wird ein Diodenstromflussintervall überbrückt oder zumindest wesentlich verkürzt.
    A controlled capacitance or inductance is coupled to a resonant circuit via an ON/OFF signal controlled switch, the resulting coupling interval comprising a subinterval of the resonant circuit period. A first state change of the ON/OFF signal is responsive to a control variable which controls the resonance frequency, impedance or admittance of the resonant circuit and a second state change of the ON/OFF signal, which is opposite to the first state change of the ON/OFF signal, is responsive to a state change of the switch. As a result, a diode current flow interval is bridged or at least significantly reduced.

    摘要: In einem ersten Aspekt der Erfindung wird eine Kapazität oder eine Induktivität über einen gesteuerten Schalter an einen Schwingkreis gekoppelt. Das Kopplungsintervall umfasst ein Teilintervall einer Periode, welche durch das resultierende Netzwerk gebildet wird. Ein Strom- oder Spannungs-Nullpunktdetektor erzeugt ein Triggersignal, welches ein Pulsweitensignal generiert. Die Pulsweite wird durch eine elektronische Stellgrösse gesteuert. Der Zustand des Schalters wird durch das Pulsweitensignal definiert.
    In einem weiteren Aspekt der Erfindung wird die Ansteuerung der Kopplungsschalter so modifiziert, dass das Diodenstromflussintervall durch zusätzliches Ansteuern des gesteuerten Schalters überbrückt oder zumindest wesentlich verkürzt wird.

    摘要: The amount of correction of horizontal linearity can be adjusted and the amplitude of a horizontal deflection current can be suppressed. A switching element (11) is provided between both ends of an S-distortion correction capacitor (5) connected in series to a horizontal deflecting coil (4), so that the switching element (11) is kept on during a horizontal blanking interval to release the electric charge accumulated in the S-distortion correction capacitor (5) and the on-time of the switching element (11) is controlled to carry out linearity correction in a horizontal cycle.

    摘要: First and second index signal phosphor layers are formed on a phosphor screen that is formed on the inner surface of a face plate. A rear plate (9) is provided with first and second light sensing units (19a, 19b) for detecting signal lights from the first and second index signal phosphor layers, respectively. Each first light sensing unit (19a) includes a first light collecting plate (30), which radiates absorbing light having a radiation peak wavelength substantially equal to or shorter than the radiation wavelength of each first index signal phosphor layer. Each second light sensing unit includes a second light collecting plate (36), which radiates absorbing light having a radiation peak wavelength substantially equal to or shorter than the radiation wavelength of each second index signal phosphor layer. Arranged between each second collecting plate and the rear plate is a filter (34), which transmits the index signal light from the second index signal phosphor layer and shades the index signal light from the first index signal phosphor layer.

    摘要: A vertical deflection signal generator for use in a digital television has a vertical oscillation circuit (2) for generating a vertical synchronization signal (fv), a vertical frequency converter (5) for doubling the vertical synchronization signal, and a vertical synchronization driver (6) for producing a vertical synchronization drive pulse in response to the doubled vertical synchronization signal (2fv). Further provided are oscillator (12) for producing a quasi vertical synchronization signal, a detector (11) for detecting the presence and absence of the vertical synchronization signal, and a switching circuit (13). When the presence of the vertical synchronization signal is detected, the vertical synchronization signal from the vertical oscillation circuit (2) is applied to the vertical frequency converter 5, but when the absence of the vertical synchronization signal is detected, the quasi vertical synchronization signal from the oscillator means (12) is applied to the vertical frequency converter 5.

    摘要: A vertical deflection amplifier (20) of a video display apparatus includes first (Q1) and second (Q2) transistor amplifier output stages arranged in a totem-­pole, push-pull configuration. A vertical-deflection winding (L V ) is coupled to the output stages at a deflection amplifier output terminal (22). An S-capacitor (C1) is coupled to the deflection winding (L V ) at a second terminal (21) remote from the output terminal (22). A source (23) of deflection rate signals is coupled to the deflection amplifier (20) for generating a deflection current (i v ) in the deflection winding (L V ). A base current generating circuit (40) is coupled to one (Q1) of the transistor amplifier output stages for providing base current (i1) thereto. The S-capacitor voltage (V1) is applied to the base current generating circuit (40) for enabling conduction of base current (i1) in the one amplifier output stage (Q1). When the video display apparatus is first turned on, the initially discharged S-capacitor (C1) is slowly charged from a DC voltage supply (+30V) to delay generation of vertical def lection past completion of picture tube degaussing. A DC power supply (16) upon energization in response to a switch (15) produces a DC level (+DC2) sufficient for operating the deflection amplifier prior to the conclusion of degaussing.
