    摘要: An apparatus for patterning a phosphor screen on the faceplate of a cathode-ray tube has a main lens that refracts light to simulate electron-beam trajectories. The main lens includes a fixed lens with a curved surface, and at least one replaceable flat element. The apparatus also has at least one sub-lens, with a curved surface, that can be substituted for the flat element to compensate for inaccurate simulation of the electron-beam trajectories. The flat element and the sub-lens have the same thickness, so that substitution of the one for the other does not produce an unintended shifting of light paths. Preferred sub-lenses include lenses having surfaces described by a bilaterally symmetric cosine function, and by a product of a sine function and a linear function.

    摘要: A cold electron emitting device has an emitter base portion, an emitter projection portion and a source region, each of which is an n-type semiconductor, formed on a p-type silicon substrate. A metal film which serves as an extraction electrode and a gate electrode of FET is formed via an insulating layer on the region of the substrate which includes the peripheral regions of the emitter base portion and source region. This cold electron emitting device can be manufactured as follows. First, a conical emitter having an emitter projection portion and emitter base portion and a source region are formed on a p-type semiconductor substrate. Next, an insulating layer and a metal film, which becomes an extraction electrode and a gate electrode of FET, is formed on the substrate which includes peripheral regions of the emitter base portion and source region. Then, an n-type impurity is doped in the emitter and the source region to form an n-type emitter and an n-type source region. In this manner, it is possible to manufacture a cold electron emitting device, which has an excellent work precision for the sharp tip of the emitter projection portion and an excellent uniform structure and can stably emit a current.

    摘要: A vibration wave motor for generating a travelling vibration wave in a vibration member by applying a periodic voltage to an electro-mechanical energy transducer. An anti-movement device is provided to contact the vibration member at a pitch not equal to a multiple of n.lambda./2, where n is an integer and .lambda. is the wavelength of a vibration wave so that the vibration member is prevented from rotating without reducing the drive efficiency of the motor.
