Title: Evaluation method for solid-state image pickup element
Inventor: NAKAYAMA HIROSHI
IPC: H04N5/335
Filed: 1992-10-22
Abstract: PURPOSE:To improve the accuracy of evaluation of roughness of picture data themselves without being affected by fluctuation of a noise output from a measured element and a measurement system by extracting noise data from the entire picture data outputted from a solid-state image pickup element and eliminating a standard deviation due to noise from the entire standard deviation of the picture data. CONSTITUTION:Picture data from a solid-state image pickup element 1 are inputted to a tester 2, in which noise data are separated from the picture data and the noise data separated are stored in a picture storage device 3 provided in the inside or the outside of the tester 2 for each picture element. Furthermore, the entire picture data are stored in the picture storage device 3 via the tester 2, in which the standard deviation sigmaen of the noise data and the standard deviation sigmae of the entire picture data are calculated respectively. Then a difference (sigmae-sigmaen) and a preset threshold level are compared to discriminate the acceptance of picture quality based on the result of comparison. Thus, the threshold level is set to a smaller level without being affected of fluctuation of noise data.

Abstract: PURPOSE:To make a character pattern for display which is superior in quality and easy to see, by a method wherein an omission processing is conducted with making the best use of a characteristic of each character pattern by using only only kind of character generator capable of high-quality printing. CONSTITUTION:Data for changing a pattern is made according to the principle, that is: the pattern is separated into three blocks; the top dot line and the bottom dot line are to be constantly the objects of omission; effective dot numbers for the other 22 dot lines are calculated by every line; in the each block, the lines of last two in order of effective dot number are to be the targets of omission. To take pattern data for a character shown by the figure as an instance, as shown as the left side and the upward of the figure, the line corresponding to the bit of logic '0' is to be the target of omission, but not the line corresponding to bit of logic '1'. In this manner, pattern data for printer is compressed to pattern data for display of 16X16 (dot), thus a pattern display of high quality can be conducted with making the best use of a characteristic of an original pattern of a character.

Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting method in which a loss of field is detected and in which a generator in the loss of field can be specified simultaneously, by a method wherein a cross current which flows across two generators in a cross compound generator in a starting operation is detected as reactive power, and it is judged according to the magnitude of the detected reactive power and according to the leading direction or the lagging direction of the reactive power. SOLUTION: A reactive-power detecting relay 7 is installed. A cross current which is generated due to a loss of field across a primary generator 2 and a secondary generator 3 is detected as reacrive power. In a cross compound power generation system, two generators are connected in parallel. When a loss of field is generated in one generator, an exciting voltage is lost in the generator. A cross current which guarantees a voltage difference is generated toward an accident generator from the other sound generator. When the cross current flows to the accident generator from the sound generator, the reactive power as viewed from the accident generator in the leading direction. On the contrary, the reactive power as viewed from the sound generator is in the lagging direction.  Consequently, when the advance or the delay of the reactive power is monitored, the loss of field of both generators can be detected.

Abstract: PROBLEM TO BE SOLVED: To provide a method for preventing record distortion in reading external radiation by scanning an amplifying micro channel plate with its saturated electron beam current from a collector electrode side by the use of an energy quantity of a secondary electron emission coefficient greater than a predetermined value. SOLUTION: Various images of radiation shapes enter through an input window 2 into an amplifying micro channel plate 3 in a housing 1. External radiation passes through a thin film photoelectric negative electrode 12 or a photoelectric negative electrode 13 and a metallic thin film 14, and is converted into photoelectron current so that the plate 3 having no sensitivity to radiation can record the image of the external radiation. The photoelectric current, which is produced when the radiation beam is interacting with the plate 3 or passing through the negative electrode 12 or 13, is generated in a channel output part, provided that the incident direction of the external radiation coincides with the amplifying direction of the plate 3. With regard to the record of the image, if a predetermined conditional equation is satisfied, a charge proportional to the input intensity is produced in each channel of the plate 3.

Abstract: PURPOSE:To increase the density and the compression strength of concrete, while the adhesion of short fibers to cement is improved by exerting a pressure on the cement, while air is injected into the fluid cement with which the short fibers are mixed. CONSTITUTION:The pressuring plate 9 for pressurizing fluid cement 8 is provided, and, e.g. one kind or a plurality of kinds of the desired fibers such as metallic fibers, glass fibers and kevlar chops, etc., as the material to be mixed, are mixed with the fluid cement.

While air is injected into the fluid cement 8 with which short fibers are mixed from an air pipe 1, when pressure is exerted on the whole fluid cement, the adhesion of the short fibers to the cement 8 is improved when the injected air becomes bubble and moves in the cement 8. Moreover, when this bubbles rises in the cement 8, and especially when it is released in the atmosphere from a gas vent 12, it bursts and the adhesion of the fiber to cement 8 is further improved by the vibrations generated by the bursting, whereby the density of the concrete and its compression strength are increased.

IPC: H03H7/01
Filed: 1990-10-23
Abstract: PURPOSE:To realize such a filter circuit that hardly receives unnecessary induction and has a high S/N by arranging the 1st and 2nd coils in the filter circuit so that induced voltages generated by external AC magnetic fields can offset each other. CONSTITUTION:A balanced secondary high-pass filter is constituted of the 1st coil 3, 2nd coil 4 having the same inductance and winding shape as the 1st coil 3 has, 1st capacitor 5, and 2nd capacitor 6 having the same capacitance as the capacitor 5 has. The coils 3 and 4 are arranged on the same axis so that their axes 3a and 4a coincide with each other in the direction in which the resultant inductance of the coils 3 and 4 decreases. Therefore, the generation of an unnecessary induced voltage can be suppressed, since the voltages respectively induced across both ends of the coils 3 and 4 offset each other between the output terminals of the filter even when the filter receives the unnecessary influence of an external AC magnetic field.
