Abstract: A projection display device includes: a dustproof filter that removes dust and a foreign material from drawn air; an air guide path that guides, to a liquid crystal panel, the cooling air blown by a suction fan; an air velocity detector that is arranged in the air guide path and detects the velocity of the cooling air that flows in the air guide path; and a CPU that determines, on the basis of the value detected by the air velocity detector, whether or not the dustproof filter is clogged. The air velocity detector detects the velocity of the cooling air by measuring the temperature of the air in the vicinity of the heat generating element that will be increased due to heat transfer generated by the heat generating element. This configuration improves accuracy in determining whether or not the dustproof filter is clogged.

Abstract: Electric charges are stored on a capacitor and then the charges are discharged so that a sawtooth wave for use in a convergence correction circuit for a display or the like is generated. When the sawtooth wave is used for a multi-scan display, the charge period is varied according as the scanning frequency varies, and as a result, a phase error is produced in the parabolic wave obtained by squaring the sawtooth wave. To eliminate the phase error, it is adapted such that the discharging current from the capacitor is passed through a coil and, in addition, the period as the reciprocal of the resonant frequency of the resonance circuit formed of the coil and the capacitor is set to be virtually double the discharge period.

Abstract: A video output circuit for driving a CRT of a grid-cathode differential drive type is disclosed, in which a collector potential of an output transistor in a horizontal blanking interval is detected by a diode arrangement; the potential thus detected is smoothed by a smoothing filtering arrangement output current of the output transistor is controlled by an output obtained by the smoothing filtering arrangement; and negative feedback control is effected so that the collector potential of the output transistor is made constant.

Abstract: A CRT display including a horizontal deflection circuit. The horizontal deflection coil supplied with a horizontal deflection signal, with inductance L, has an energy-dissipating coil resistance connected in series and hence a second-order distortion expanding the left-hand side of the picture screen of the display and contracting the right-hand side thereof is produced. In the preset invention, to correct for the second-order distortion, the current flowing through the deflection coil means is detected, the deflection distortion component is extracted from the current, and a deflection distortion correcting current corresponding to the deflection distortion is supplied to an auxiliary coil for correcting the horizontal deflection of the electron beam.

Abstract: A horizontal deflection circuit which including a horizontal output transistor; a damper diode connected in parallel with the horizontal output transistor; a resonant capacitor connected in parallel with the damper diode; a horizontal deflection coil connected in parallel with the horizontal output transistor; and a series resonant circuit connected in parallel with the resonant capacitor. The series resonant circuit is constituted by a series connection of a capacitor and an inductor to perform composite resonance in cooperation with the resonant capacitor. The capacitor and the inductor of the series resonant circuit are designed to have a tertiary resonant frequency. The composite resonance by means of the series resonant circuit and the resonant capacitor enables the top of the flyback pulse to be flattened, so that the waveform of the flyback pulse becomes near the form of rectangular wave. Accordingly, a horizontal deflection circuit having higher retracing capacity can be provided through the same horizontal output transistor as generally used in the prior art.

Abstract: A CRT display device capable of displaying a signal from the existing image signal source, in which a vertical frequency is approximately fixed and a horizontal frequency is widely distributed beyond a ratio of 3:1, on one image screen. The CRT display device includes a scan converter unit and a display unit. The scan converter unit includes an output horizontal frequency unifying circuit, a horizontal blanking period ratio converting circuit, a vertical frequency converting unit and a vertical blanking period ratio converting circuit. The display unit includes a vertical deflection circuit and a circuit for correcting a vertical S-shaped distortion. In a phase synchronous circuit, a lock-out detector is connected to an output of a three state output digital phase detector, and on the basis of an output thereof, a switch is subjected to the "ON"/"OFF" control. For a period of time when an output of the lock-out detector indicates a lock-out state, a loop gain of the PLL is increased and the pull-in time is shortened. For the remaining periods of time, i.e., in the steady state, the loop gain is decreased and the noise resistance characteristics are improved.
