摘要： Pixel portions of a photoconductive layer each have a pin structure for providing a rectifying function and are substantially electrically isolated from one another by a highly resistant inter-pixel portion for preventing diffusion of electrical carriers. Data written into a liquid crystal layer by writing light is read out as an optical output by reading light. Reflecting films are provided on the pixel portions, respectively, and an output light blocking film is provided on the inter-pixel portion formed into a groove. The reflecting films and the output light blocking film are partially overlapped on each other so as to sufficiently block the reading light.

摘要： A two-dimensional bit image generated by the input device is processed by a four-layer neural network and recognized. The neurons in the second layer are connected only to the neurons of the first layer aligned in a specific direction, thereby enabling the second layer to extract line components in specific directions. The second layer is further divided into plural regions, and all neurons in each region are connected to one corresponding neuron in the third layer. The output of the third layer neurons thus express the position and degree of the extracted line component in the image. All of the neurons in the third layer are connected to all of the neurons in the fourth layer, and image recognition is possible by learning.

摘要： A method and apparatus for manufacturing an ultrafine particle film which has great practical utility when deposited on an appropriate substrate. The particle film is produced from various ultrafine particles of, for example, metals, oxides, nitrides and carbides, and is produced uniformly, effectively and efficiently with a high degree of reproducibility. According to a first method, an atmosphere at a gas of a reduced pressure is formed in a vessel, and a forced flow of the gas is formed unidirectionally from an evaporation source to the substrate, so that the evaporated matters from the evaporation source are forced to move together with the forced flow of the gas, so that ultrafine particles which are formed through interaction between the evaporated matters and the gas deposited on the substrate thereby forming the ultrafine particle film. According to a second method, the evaporation source is disposed within a vessel of having a reduced gas pressure as well as a cylinder surrounded by a high-frequency coil. As the coil is energized, the gas in the cylinder is excited. The evaporated matters are forced to flow through the excited gas atmosphere so that ultrafine particles formed by an interaction between the evaporated matters and the excited gas are deposited on the substrate thereby forming the ultrafine particle layer. A third method is a combination of the first and second methods.

摘要： A method and apparatus for forming an array of microcavities in the surface of a metal film uses an excimer laser or an ultrashort laser which to produce a beam of laser light pulses. An optical mask divides the beam into multiple beams and a lens system focuses the multiple beams onto the metal film. The device operates by generating multiple beams of laser pulses of a first diameter and then magnifying the pulses by a magnification factor less than 1 to produce multiple beams of pulses having a second diameter, less than the first diameter, which are applied to the metal film. The magnification factor and the intensity of the laser is such that the fluence of the laser on the optical mask is not sufficient to cause ablation while the fluence on the metal film is sufficient to cause ablation. A diffractive optical element may be used in the device in place of the optical mask. The apparatus includes a quarter wave plate that converts the beam of laser light pulses into a beam of circularly polarized pulses. The apparatus also includes a device that homogenizes the intensity of the laser light pulses before they are applied to the optical mask.

摘要： A diffractive optical lens of the present invention comprises a grating zone having a plurality of elliptical grooves which are similar in shape to each other so that each major axis is coincided. When light is obliquely incident, it is diffracted by the grating zone and is focused with any astigmatism thereof corrected. The center of each elliptical groove is shifted in one direction of the major axis direction, so that the light which is diffracted is focused with the coma corrected. As a result, even when light is obliquely incident, satisfactory focal characteristics can be obtained without aberrations.
