摘要： A video display (10) includes a scanner (100) operable at a first frequency (H1) and a higher second frequency (H2). A switchmode power supply (SMPS) (32) drives a transformer (T1) with three secondaries (T1S1b, T1S1a and T1S2). First and second rectifiers & filters ((CR107, CR108) and (F101, F102)) are associated with the first and second secondaries. A rectifier is coupled to the third secondary (T1S1b) and by way of a switch (K2) to the first filter (F101). Feedback from the first filter (F101) controls the SMPS (32). In a first operating mode, the scanner (100) is operated at the first frequency, the switch is open, the scanner supply (SCAN +) is a first voltage from the first filter (F101), and ancillary equipment is supplied with a third voltage by the second filter (F102). In a second operating mode, the scanner (100) is operated at the second frequency, the switch (K2) is closed, the scanner supply (SCANB +) is a second voltage, higher than the first, from the first filter (F101), and ancillary equipment is supplied with the same third voltage.

摘要： A dynamic focus amplifier (17) for generating a dynamic focus voltage for a focus electrode for a cathode ray tube (12) at a capacitive load (C602, C wire, CTl) includes a source of a periodic signal at a horizontal deflection frequency. A pulldown transistor (Q1) is responsive to the periodic signal and coupled to the capacitive load (C602, C wire, CTl) for producing, in accordance with the periodic signal, a first portion of the dynamic focus voltage that decreases, during a first portion of a period of the periodic signal. A storage capacitor (C501) is coupled to the capacitive load (C602, C wire, CTl) for replenishing a charge stored in the storage capacitor (C501) from a charge stored in the capacitive load to develop a control voltage in the storage capacitor (C501). A pull-up transistor is responsive to the control voltage and coupled to a source of a high voltage and to the capacitive load (C602, C wire, CTl) for producing from the high voltage a current that is coupled to the capacitive load. The current develops a second portion of the dynamic focus voltage that increases, during a second portion of the period of the periodic signal, and stores the charge in the capacitive load (C602, C wire, CTl).

摘要： Beam control pulse modulation (CPM) in an RF transmitter tube (101) is provided by a solid state switch on (S1) connected between the cathode power supply (103) and the cathode (102) of the transmitter tube. The beam controlling element (104) is returned to the normal cathode power source such that closing the switch (S1) between the two cathodes and the cathode power source brings the beam controlling element voltage to cathode potential causing beam current to flow, while opening the switch (S1) provides a very high equivalent cathode resistance, which self-biases the tube in the cutoff region, eliminating the need for a separate "off" voltage power supply. Off-edge performance may be further improved by providing an off switch (S2) connected between the cathode (102) and a collector tap on the cathode power supply (103), and closing the switch (S2) when the on switch (S1) is opened to accelerate return of the cathode potential to the cutoff voltage.

摘要： Disclosed is a photographic printer (100) with bi-directional sweeping of a monochrome CRT (116) to expose a photosensitive medium. Image data from a host system is received by the printer and stored in a data drive system (112). The data drive system (112) converts the data into a series of rows of dot row data to produce the appropriate image desired. Linear deflection amplifiers sweep the CRT's electron beam across the face of the CRT (116) to expose the medium utilizing the dot row data. The present invention sweeps and writes data bi-directionally, eliminating the retrace period associated with sweeping and writing in one direction, and without any hold periods once printing starts. The data in every other dot row is processed in reverse order so that the dot row data utilized in the reverse writing sweep will be exposed onto the medium in proper relationship to the rows written above and below it.

摘要： Disclosed is a photographic printer with bi-directional sweeping of a color CRT (116) to expose a photosensitive medium (120). Image data from a host system is received by the printer and stored in a data drive system (112). The data drive system (112) converts the data into a series of rows of dot row data to produce the appropriate image desired. Linear deflection amplifiers sweep the CRT's electron beam across the color phosphor areas on the face of the CRT (116) to expose the medium (120) utilizing the dot row data. The present invention sweeps and writes data bi-directionally, eliminating the retrace period associated with sweeping and writing in one direction, and without any hold periods once printing starts. The data in every other dot row is processed in reverse order so that the dot row data utilized in the reverse writing sweep will be exposed onto the medium (120) in proper relationship to the rows written before and after it.

摘要： A signal is sent to a deflection circuit and a video signal processing circuit. On receiving the signal, the deflection circuit outputs a vertical deflection signal and a horizontal deflection signal. The vertical deflection signal is sent directly to a deflection yoke while the horizontal deflection signal is sent via an S-shaped wave modulation circuit to the deflection yoke. On the other hand, the video signal processing circuit receives the signal and outputs a video signal via an amplitude modulation circuit and a frequency modulation circuit to a cathode of an electron gun. The S-shaped wave modulation circuit performs modulation on the horizontal deflection signal to change scanning speed. The amplitude modulation circuit and the frequency modulation circuit perform, on the video signal, amplitude modulation and frequency modulation which are appropriate for this speed.
