摘要： A cathode includes emitter tips provided on a substrate, a gate electrode with an electric field formed between the gate electrode and the emitter tips, and terminals and leads for supplying voltages to the emitter tips and the gate electrode, respectively. A shield electrode further is provided between the cathode and a control electrode, and the shield electrode has a cylindrical projecting portion projecting toward the cathode, through which electron beams pass. The disturbance of an electric field by the leads influences the electron beams; however, this can be prevented by the projecting portion. Because of this, even if the size of the cathode is reduced, the distortion of an electron beam spot on a phosphor screen can be reduced. As a result, a cathode-ray tube with high resolution can be provided at a low cost.

摘要： In conventional methods of correction luminance in displays, it has been necessary to interrupt video display during use in order to carry out correction. This is a problem in that interruptions are not good for workability from the perspective of the user of the image display device. In consideration of this, the present invention realizes a display without non-uniformity in illumination with respect to both initial characteristics and change over time by measuring anode current of an FED and creating a luminance correction memory. In addition, by illuminating arbitrary pixels during video idle periods, capturing the luminance information from the pixels, and renewing a correction memory based on this luminance information, correction for change over time is possible without interrupting video display. Thus, a display device that can maintain high quality images is provided.

摘要： A cathode ray tube according to the present invention include a cold cathode electron gun, the cold cathode electron gun including a cold cathode array for emitting electrons through field emission, a gate electrode for controlling the field emission, a first selective electrode provided around the cold cathode array and the gate electrode, and a second selective electrode opposing the first selective electrode, and the second selective electrode is adapted to have a lower potential than the gate electrode and the first selective electrode. In accordance with this configuration, the divergence of electron beams emitted from any positions in the cold cathode array can be converged uniformly upon removing electron beams emitted at a great emission angle. This allows the electron beams thereafter to be made narrower by an electrostatic lens. As a result, the present invention can provide a cathode ray tube capable of forming a high-resolution image.

摘要： An electronic ignition control device for determining and maintaining a vehicle at the optimum spark advance for different ranges of crankshaft rotation speeds and ratios of air intake to crankshaft rotation speed. Signals indicating a range in which the instantaneous rotation speed falls and a range in which air intake/speed ratio falls define a ROM address at which is stored an optimum spark advance angle for that combination of ranges. The signal indicating the stored angle is applied to a discriminator which also receives inputs from a crank switch monitor, a throttle switch monitor and a coolant temperature sensor. When cranking or idling is detected, the discriminator substitutes a cranking advance or idling advance angle for the stored optimum advance angle signal.

摘要： The object of the present invention is to provide a driving method and a driving apparatus for a field emission device that controls emission current with stability regardless of how long the device is driven. The field emission device driving method and driving apparatus of the present invention set the actual emission current at a reference level by adjusting the amount of current which is supplied to the emitter to a reference level. The amount of current supplied to the emitter is adjusted to the reference level by increasing the driving voltage in response to driving time elapsing in a state in which the electron emission performance is sustained above the reference level. By adjusting the amount of current supplied to the emitter in a state in which the driving voltage is sustained higher than the minimum voltage, a stable amount of emission current can be sustained and electron emission without fluctuations can be realized, even when the performance of the field emission device in emitting electrons deteriorates due to driving time elapsing.
