摘要:
An X-ray image pickup device has a two-dimensional image reading device which is constituted by two-dimensionally forming a plurality of photoelectric conversion elements on an insulating substrate, and has switching elements in the vicinities of these photoelectric conversion elements, a phosphor which is formed on the two-dimensional image reading device and serves as a wavelength converter for converting X-ray radiation into visible light, and a grid plate which is formed on the phosphor and guides only X-rays from a specific direction toward the phosphor and the two-dimensional image reading device, whereby a next-generation X-ray image pickup device which can improve diagnostic efficiency that cannot be attained by the conventional film method, and has a high space factor and a high S/N ratio that cannot be attained by the CCD method can be provided.

A reading device for illuminating a light beam emitted from at least two light emitting elements of different light emission wavelength ranges to an original through a light conductor prevent irregularity of illumination on the original without providing compensation means to attain improvement in color discrimination ability of a color document sheet read signal without increasing a cost. A light beam applied from an illumination device 30 arranged at an end of a light conductor 3 is scattered and reflected by a scatter and reflection area 5 of the light conductor to illuminate the original 100. The illumination device 30 has at least two light emitting elements 81G and 81R of different light emission wavelength ranges and centers of the light emitting elements are arranged at positions spaced from a normal line passing through a center of the scatter and reflection area 5.

A photosensor with improved correction of image signals has a first photosensor portion including a plurality of photoelectric converting devices for reading an object and providing image signals thereof. A second photosensor portion includes a plurality of photoelectric converting devices and provides reference signals from light reflected from a reference member, or light received directly from a light source. Correction circuitry corrects the image signals from the first photosensor portion in accordance with the reference signals output from the second photosensor portion. Preferably, the photoelectric converting devices of the first and second photosensor portions are arranged in adjacent, parallel lines on the same substrate. Preferably, reference signals from the converting devices of the second photosensor are used by the correction circuitry to correct the electrical signals from substantially adjacent converting devices of the first photosensor portion. A single converting device of the second photosensor portion may be used to correct either one or more of the converting devices of the first photosensor portion.

A sample moving apparatus for positioning wafers with high accuracy, which apparatus comprises a fine adjustment actuator having a drive stroke to finely move the wafer, a fine adjustment stage driven by the fine adjustment actuator, a coarse adjustment actuator having a drive stroke to relatively coarsely move the wafer, a coarse adjustment stage driven by the coarse adjustment actuator, and a holder arrangement for attractively holding the wafer onto the wafer bearing surfaces of the respective stages. Upon selective energization of the holder arrangement of the respective stages, the wafer is moved while being attracted to the coarse adjustment stage or while being attracted to the coarse adjustment stage.

A rigid polyurethane foam produced by reacting a special polyol component with an isocyanate component in the presence of a blowing agent containing water in an amount of 2 to 3.5% by weight per 100% by weight of the polyol component is excellent in fluidity with balanced excellent properties.
摘要:
With the operation of character select keys, alphanumeric data stored in a ROM are successively read out and latched in a latch circuit under the control of a CPU. The call sign data of a received channel assembled in the latch circuit are stored together with the frequency data of that received channel in a RAM. The call sign data preset in this way is read out from the RAM by taking out the frequency data from the tuner and using it as address means and is visually displayed on a display unit while being informed of as voice by a voice synthesizer.
摘要:
A method for estimating the geographical distribution of a cohesive zone in a blast furnace which is intermittently charged with an iron ore material to produce molten iron substantially in a continuous manner is disclosed. The method comprises altering the whole or part of the composition of the charging iron ore material at a certain time point, measuring variations in the composition of produced molten iron ore slag over a given time period, and estimating the shape of the cohesive zone in the furnace on the basis of a pattern of variation of one selected component and the speed of gravitational descent of the charged material through the furnace.
