Title: Semiconductor device
Inventor: KUSUSE NORIO
IPC: H01L21/8222
Filed: 1979-02-07
Abstract: PURPOSE:To obtain a junction-break type memory that requires less energy for writing by making the space between the base-collector junction and the base-emitter junction approximately fixed in the direction of the surface, side and depth of the base layer. CONSTITUTION:The N<+> embedded collector layer 2, N epitaxial layer 3, shallow P-type base layer 4, N<+> emitter layer 5, collector electrode layer 6 and SiO2 film 7 that is selectively oxidized by the use of Si3N4 masks are formed on the P-type substrate 1. Also the base layer 4 and the emitter layer 5 are formed the same opening by a diffusion process. In this way, the oxidation proceeds also in the lateral direction of the substrate when selectively oxidized by the use of Si3N4 masks, the effective junction area can be made less than the designed value. Also, since the emitter-base junction is formed by self-matching, the element area can be reduced. Accordingly energy required for the writing can be reduced, a junction- break type PROM that has a high integration and is capable of high speed operation can be obtained.

Abstract: PROBLEM TO BE SOLVED: To suitably correct uneven illuminance, without causing processing complications, even when the photographing is performed after the correction of geometric distortions. SOLUTION: The oblique image of character information on a white board, that is obliquely photographed by a CCD 20, is stored in an image memory 322 and also divided into plural small images at a 1st γ-characteristic setting part 323 for correction of the uneven illuminance. The γ-characteristic is set for every small image, based on the pixel data forming the small image. Then the oblique image recorded in the memory 322 undergoes a γ-correction at a 2nd γ-correction part 326, based on the γ characteristic corresponding to every small image and is corrected into a pseudo-front image at an oblique image correction arithmetic part 327. Thus, it is possible to set a proper γ-characteristic for every small image by correcting the oblique image after the uneven illuminance is corrected.

Title: Measurement of weight by detection of strain
Inventor: WATANABE IPPEI
IPC: G01L3/04
Filed: 1990-01-22
Abstract: PURPOSE:To facilitate the determination of a weight dispensing with a specialized weight measuring means by detecting a distortion of a transmission member during a traction to measure the weight of test specimen. CONSTITUTION:When power is transmitted for traction of a test specimen 1, a transmitting member 3 is deformed to be twisted. To detect the deformation, marks (lines) 4a and 5a to be detected are provided 4b and 5b on outer circumferential surfaces of joints 4 and 5 being separated at an interval l. With the twisted deformation of the member 3, the marks 5a and 5b are deviated by DELTAx from the marks 4a and 4b. A difference DELTAT4 between time T41 when the mark 4a passes a counter point of a sensor 11 and passage time T42 is equal to a difference DELTAT5 in the joint 5 and hence, the DELTAT4 = DELTAT5 = DELTAT. A difference between the times T41 and T51 is put at DELTAt and the following specified computation is performed to determine a torque and a traction force. Thus, a weight Wn of the test specimen 1 can be determined from detection values of DELTAt and DELTAT.

IPC: G06T5/20
Filed: 1995-01-31
Abstract: PURPOSE: To obtain a noise reduction picture while minimizing the blur of an edge and density irregularity to a picture of low S/N. CONSTITUTION: This method executes a step 101 giving desired low pass filter processing to picture data, a step 102 calculating the magnitude of density change in the direction of straight line components concerning each straight line component passing through the picture element by each picture element of a low-pass-filter-processed picture, a step 103 obtaining the straight line component minimizing density change and a step 104 executing one-dimensional nonlinear smoothing processing by limiting to the straight line component of an original picture provided with the same direction as the straight line component of minimum density change obtained from the low-pass-filter-processes picture by each picture element of the original picture.  Thus, as the straight line component of minimum density change in the low-pass-filter-processed picture is detected, a straight line component which is not affected by noise can be detected to one-dimensionally smooth by limiting to the straight line component provided with the directions. Thereby, while saving a false picture made by the structuring of noise components and minimizing the deterioration of space resolution, noise is effectively reduced.

Abstract: PURPOSE: To store and notify the traveling locus point information of a vehicle. CONSTITUTION: A positioning system 11 comprising a GPS receiver, for example, acquires the traveling locus point information of a vehicle, e.g. longitude, latitude, traveling speed and time. A CPU 17a arranges the information in the order of positioning time to prepare a traveling locus point information table which is stored in a RAM 17c. When a locus point is designated on a map by means of an input unit 21, the CPU 17a retrieves the longitude and latitude at that point based on the map information from a CD-ROM 13 and reads out the traveling focus point information corresponding to the designated locus point from the RAM 17c. The traveling locus point information is converted into character information which is presented on a display 19.

IPC: B66F19/00
Filed: 1990-01-23
Abstract: PURPOSE:To eliminate dispersion of a stable position of a load-carrying platform by means of a relatively simplified structure by operating movable stoppers in accordance with weight of a cargo to change a number of tensile springs, effective for pulling up the load-carrying platform, and adjusting its pulling up force stepwise. CONSTITUTION:When stop pawls 23 of movable stoppers 16a to 16c are placed in a longitudinal direction, a load-carrying platform 4 is urged upward by only a pair of tensile springs 9a, 9b. When a cargo is loaded on the load mounting part of the load-carrying platform 4, it is stopped in a position where a load is balanced with force of pulling up the load-carrying platform. When the upper end level of the cargo is placed in an excessively low position because the handled cargo is heavy, intermediate three tensile springs, 10a to 10c are selectively used to assist pulling up the load-carrying platform. For instance, when the pulling up force is assisted by the central tensile spring 10c, the stop pawl 23 of the central movable stopper 16c is engaged with a stopped part 30 of a spring receiver 17c when the load-carrying platform 4 is placed in the upper limit position.

Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method in which the coating quality of a metallic coating, a pearl mica coating or the like is evaluated quantitatively over a wide range while the distribution of a deformation luminance value or the distribution of a deformation RGB value is used. SOLUTION: In an imaging illumination head part 4, a two-dimensional imaging part 2 such as a CCD camera or the like and a light source part 3 are held in a prescribed positional relationship. In a state that the two-dimensional imaging part 2 is faced with the coating face of an object 5, to be measured, at a prescribed distance, the object 5 to be measured is photographed repeatedly while the imaging illumination head part 4 is being moved. A plurality of images are obtained in a state thatradiant angles of a beam of light reflected from an identical point on the object 5 to be measured are different from each other. A data processing part 8 extracts the luminance value or the RGB value of the identical point on the object 5, to be measured, from the plurality of images.  Thereby, the distribution of a deformation luminance value or the distribution of a deformation RGB value is found. The data processing part 8 evaluates the optical reflection property of the object 5, to be measured, on the basis of the distribution of the deformation luminance value or on the basis of the distribution of the deformation RGB value, and an evaluated result is displayed on a display part 9.
