    摘要: A method of converting a color negative image into an inverted positive color image and an apparatus for carrying out the method. The image of the color negative film is decomposed into three images each in one of the three primary colors through associated color filters. The individual images thus produced are recorded in a light transmissive recording medium in inverted images, which are then illuminated by a light source disposed at a side in opposition to the negative film, whereby the inverted images are projected through the same optical system including the aforementioned color filters as the one used for the projection onto a screen as the inverted positive image. The recording medium is constituted by a light transmissive ceramic dielectric exhibiting a memory function. The inverted positive image may be projected at a magnified scale.

    摘要: An image display device comprises first and second polarizers having their planes of polarizations oriented at right angles to each other and an electrooptic plate of ferroelectric ceramic material interposed between the first and second polarizers. A matrix electrode arrangement is secured to one surface of the ceramic plate to cause crystallographic structural changes to occur under the influence of a locally generated electric field, so that light passing through the first polarizer is refracted by an amount proportional to the magnitude of the electric field and emerges from the second polarizer with an intensity proportional to the electric field. The electrode arrangement includes a plurality of row electrodes and a plurality of column electrodes to define a plurality of elemental picture areas. In each elemental area the electrode arrangement includes a diode, first parallel finger electrodes connected to a row electrode via the diode and second parallel finger electrodes connected to a column electrode and staggered relative to the first finger electrodes.

    摘要: The optical density and/or the reflectivity of a recording layer included in an optical disk is selectively changed to record information by irradiation with a semiconductor laser beam, while the recording layer may be covered with a suitable protective film. The thickness of the recording layer is so determined that it is able to record information by means of a continuous wave type semiconductor laser beam, while the optical absorption rate of the recording layer is adjusted by setting the percentages of particular additives. The recorded information may be reproduced by the application of a laser beam, the incident power of which is lower than that of the recording beam, to detect the reflected light.

    摘要: A radiation quantum-counting method and apparatus for producing high resolution radiographic images capable of discriminating soft tissue cancer having a lcm size. The high resolution image is generated by a plurality of radiation sensitive elements, each element including a semiconductor material having a pair of electrodes mounted on opposite faces thereof. Each element is highly sensitive and produces a rapid pulse count since the thickness of the semiconductor material is substantially 0.1-0.5 mm, and the semiconductor material has an effective atomic number greater than 30 and an energy band gap greater than 1.3 eV. As a plurality of radiation quanta emanate from the radiation source, they are received by the plurality of radiation sensitive elements which detect individual radiation quantum and produce a pulse signal for each detected quantum. Coupled to each radiation sensitive element is a pulse amplifier for amplifying the pulse signals. The amplified pulse signals are counted and used to produce radiographic image signals containing details of image gradation. The pulse count may also be stored in a memory and used to provide two-dimensional information when combined with other pulse count data derived when the spatial orientation between the objective body and the radiation source is changed.
