    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： A method of thermoluminescent dosimetry employing infrared radiation heating of a dosimeter. An incandescent lamp is used for the source of infrared radiation. The dosimeter is provided with a infrared radiation absorbing layer connected thermally to a thermoluminescent material layer. The infrared radiation absorbing layer is irradiated with infrared radiation, so that thermoluminescent material is not directly irradiated. The lamp is initially powered whereby the dosimeter is heated by infrared radiation of such high intensity as to tend to cause a heat equilibrium in the dosimeter above the temperature where thermal radiation is generated from the dosimeter. Then the power supplied to the lamp is cut or decreased, so that the dosimeter is heated by the afterglow of the lamp. Therefore the rate of temperature rise of the dosimeter becomes quite slow in the latter half of heating process, whereby the temperature of dosimeter easily falls into the required range.

    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 infrared optical fiber is disclosed which has a composition ratio of silver chloride and silver bromide in the range of 30 to 70 percent by weight of silver chloride, and has a diameter of 0.5 mm or less. The infrared optical fiber has great mechanical strength, so that it does not burn because of degradation in the laser beam transmission capability, even after 2,000 times of repetitive bending with a curvature radius of 20 mm, which is the condition necessary for use within the interior of a body, and it exhibits excellent radiant optical characteristics. In particular, an infrared optical fiber with a diameter of 0.35 mm or less is preferred, because such an infrared optical fiber withstands over 10,000 times of repetitive bending under the same condition as above and can therefore be repeatedly used many times. Also, by applying an appropriate load to the infrared optical fiber, the infrared optical fiber, which is of straight shape free from curving and which has excellent radiant optical characteristics, can be produced stably with a short manufacturing period of time. Furthermore, an optical fiber cable using such an infrared optical fiber, in which the infrared optical fiber is housed in a protective tube containing a dry inert gas, can be repeatedly used under wet conditions of high humidity and can be stored under ambient conditions for a long period of time.
