Abstract: PROBLEM TO BE SOLVED: To provide the spectral camera multiplexer and demultiplexer optical component which makes quadrilateral spectral response and has a waveguide array. SOLUTION: This component has waveguide arrays 3a and 3b, a star entrance coupler 1, a star exit coupler 2, an entrance light guide for the star entrance coupler, and an exit light guide for the star exit coupler, and the waveguide arrays 3a and 3b extend the part between the star entrance coupler and star exit coupler. The spectral response of this invented spectral camera multiplexer demultiplexer optical component is nearly the sum of two Gaussian spectral responses of peaks shifting in wavelength.

Abstract: PROBLEM TO BE SOLVED: To provide a high resolution screen free from smears speedily without providing any shutter by providing an electronic image pickup tube, which is provided with pixels with a specific dimension and performs scanning and focusing by means of electron beams for an optically formed image on a photosensitive target consisting of monocrystal semiconductor material so as to output an electric signal, a control means for the electronic image pickup tube, and a signal storing means. SOLUTION: In a photosensitive target 6 in a monocrystal semiconductor with a thickness of 300mμ or more, a matrix of pixels, which occupy a surface area of less than 10μm and are provided with small capacitance, is formed, and high frame speed and resolution are provided. An image of a scene 12 is formed on the target 6 by means of optical means 10, and its scanning and focusing are carried out with electron beams 16 from an electron gun 14 according to electrostatic scanning controlled by means of a first electronic processing means 20 and by means of focusing means 18, and then, an electric signal S is outputted. A signal S from an electron image pickup tube 4 is stored in controlling-storing means 22 controlling the processing means 20, and an image is displayed by means of a display means 26 after processing by means of a second electronic processing means 24 is carried out.

Abstract: PROBLEM TO BE SOLVED: To utilize a programmable BTC circuit by allowing a receiver to arrange a sample whose absolute value shows highest reliability at the position of an input matrix corresponding to the decided position of a second binary matrix. SOLUTION: At the time of receiving the sample of a signal R(t), a processor 66 forms an input matrix R} corresponding to the designated position of Y to prepare matrixes R'} and D} to store in a suited address. In basic decoding, suited samples concerning vectors [R'], [D] and [R] are supplied for a basic decoder 65. New values concerning [R'] and [D] are next recorded. In these processing, the processor 66 sequences reading or writing to the memory 67. At the last of m-cycles, the processor 66 sequences reading operation at the suited address of the memory 67 in order to send the output signal Z(t) of the basic decoder 65.

Abstract: PROBLEM TO BE SOLVED: To supply an expression of an optical scene by Walsh-Hadamard transformation. SOLUTION: As N×N electric signals, N×N radiation measurement parameters showing an actual two-dimensional optical scene are measured to generate N×N weighting functions, i.e., masks coupled with the N×N electric signals, the N×N electric signals are directly weighted with the N×N corresponding masks, and the weighted electric signals are added to obtain N×N Walsh-Hadamard transformation coefficients (X (n, m)) showing the picked up optical scene. The image pickup includes a matrix 10 of optical detecting elements (Pij), Walsh function generating and storing blocks (12, 14), and a module 16 for weighting the electric signals by a function calculated from all Walsh functions and totalizing the weighted signals.

Abstract: PROBLEM TO BE SOLVED: To avoid radio interference by conducting information exchange and energy transmission between a memory card being a carrying object and a station through electromagnetic coupling so as to separate an energy transmission function and a clock function from a data transmission function. SOLUTION: An information transmission block 13 of a station 12 is provided with a series circuit including a voltage generator G1 and an inductive element L1. On the other hand, an information transmission block 11 of a carrying object 10 is provided with an inductive element L1, an electronic circuit 3 being a resonance circuit and an object processing means 5. Information to the station 12 is sent by a phase difference between voltages VEY and VEX induced resulting from switching the electronic circuit 3. The information is sent from the station 12 by switching an electronic circuit 30 when an AC signal is applied to the inductive element L1 and a voltage is induced in an inductive element L30. A power supply 7 is not required by energy transmission through other electromagnetic coupling.

Abstract: PURPOSE: To provide a multifunction electronic part, especially a negative dynamic resistance element of an extremely miniaturized integrated structure which requires only a small number of masks for manufacturing, and its manufacturing method and a use method. CONSTITUTION: The electronic part contains first semiconductor regions 12, 13, 3, 4, 20 which are incorporated in the same semiconductor structure phasically and can form an insulation gate field-effect transistor and second semiconductor regions 12, 20, 18, 19, 11 which can form a lateral bipolar transistor. The two regions have a common semiconductor layer 20 and a channel of a field-effect transistor can be formed inside it, a base current of a bipolar transistor can flow, and a structure wherein the two regions can show negative dynamic resistance together can be formed.
