Title: Method and device for displaying linear graphic
Inventor: TANAKA HIROYUKI
IPC: G09G5/20
Filed: 1989-06-30
Abstract: PURPOSE:To identify a linear graphic even when it is overlapped with the part of any luminance in a picture by displaying the linear graphic with an alternated pattern for each picture element by the gradation color of the high luminance and the gradation color of the low luminance. CONSTITUTION:A display control circuit 2 of a CRT display device 1 writes respective picture data to a multi-gradation picture display picture memory 4 and a picture memory 5 for linear graphic display. For the data in the memories 4 and 5, one of the two kinds of the data are selected by a picture overlap circuit 6 and displayed on a CRT display part 7. In such a device 1, the linear graphic is displayed by using the gradation color of the high luminance and the gradation color of the low luminance according to the alternated pattern for each picture element. Accordingly, the part of the low luminance in the linear graphic is emphasized in a part, where the linear graphic is overlapped with the part of the high luminance in the picture. Reversely, in a part where the linear graphic is overlapped with the part of the low luminance, the part of the high luminance in the linear graphic is emphasized. Then, the linear graphic is displayed on the display part 7 in such a way. Accordingly, the linear graphic is easily identified.

IPC: B29C57/00
Filed: 1982-09-24
Abstract: PURPOSE:To obtain a fiber reinforced composite member having high strength, by using a metal or a resin to bind a reinforcing fiber bundle which is made highly dense by utilizing a heat-shrinkable tube. CONSTITUTION:A reinforcing fiber bundle 2 is packed in a heat-shrinkable tube 3. The packing is usually accomplished manually. The tube 3 packed with the bundle 2 is heated to shrink thereby increasing the packing density of the reinforcing fibers 4. The reinforcing fiber bundle having the density higher than the density of the conventional reinforcing fiber packed in a cylindrical case of steel or the like is thus obtd. In the case of binding such reinforcing fiber bundle having high density with a metal, the fiber bundle is loaded as it is in, for example, a case for impregnation, or in a metal mold for casting by high pressure solidification, then the case or the mold is heated to burn off the tube 3. In succession, the above-mentioned case is dipped in molten metal or the molten metal is charged into said metal mold to bind the bundle 2, whereby a composite member 1 is obtd.

Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To quickly and surely detect corresponding points of a plurality of images by estimating a virtual small area in the image, calculating a plurality of parameters based on information of each pixel point in the area and carrying out a predetermined process. SOLUTION: According to the method for measuring a distance by a parallax with the use of, e.g. two cameras, images of an object are first taken by the cameras set right and left or the like in a step S1. After a luminance level is corrected, a small area composed of optional p×q pixels is estimated in a step S3 and, e.g. four parameters related to a luminance data distribution in the small area are calculated for all pixel points. Direction coefficient data in which a relationship of parameters of one pixel point and surrounding eight pixel points is coded is calculated in a step S4. Direction coefficient data of right and left pixel points are compared in a step S5. The pixel points are judged as an identical point of the object when the data agree.  A parallax of corresponding pixel points of right and left images is obtained and a distance to the object is calculated in steps S7 and S8.

Abstract: PURPOSE:To obtain an insulated oxide film free from peripheral projection by forming a concave section in an epitaxial layer, which is converted at the part therof under the concave section into an oxide film by heat treatment and covered on the periphery of the side wall thereof with an oxidation resisting film when the epitaxial layer grown on a semiconductor substrate is isolated like islands with the oxide  film. CONSTITUTION:An N type layer 11 is epitaxially grown on a P type Si substrate 10 and with a photoresist as mask, an etching is made to form several inclined concave sections 12 in the layer 11. Then, after an buffer oxide film 13 is produced on the entire surface of the layer 11 including the concave section by heat treatment, an Si3N4 film 14 is grown as oxidation resisting film on the film 13. A photolithography is conducted to remove the bottom part of the film 14 leaving a part thereof from the inclined side wall of the concave section 12 to the surface thereof thereby exposing the film 13. Thereafter, with the film 14 left as mask, a heat treatment is conducted to convert the epitaxial layer under the film 13 into an SiO2 film 16 whereby the layer 11 adjacent thereto is isolated like islands. Accordingly, the existence of the film 14 prevents the generation of any projection at the end of the film 16.

Title: Printer
Inventor: FUTAKI IPPEI
IPC: B41J2/27
Filed: 1985-07-31
Abstract: PURPOSE:To enhance the quality of printing without any difference in the printing densities of printing pins by a method in which exciting coils for printing pins set on the central, upper, and lower parts of the printing head are made different in turns. CONSTITUTION:By supplying drive pulse current from an electric circuit to a coil, an armature integrally formed with printing pins 4 and 4' is attracted, and the tips of the pins 4 and 4' collide with a printing paper to print desired dots. When the pulse current is removed, the pins 4 and 4' restore to the initial positions under the tension of a returning spring. In this case, since the number of the turns of the coil serving to project the upper and lower pins 4' is more than the turns of the coil of the central pin 4, the moving amounts of the pins 4 an 4' are differentiated by the difference in magnetic force. The response of the pins 4' to the central pin 4 can be corrected. The difference in printing densities of the printing pins can thus be eliminated and the quality of printing can be enhanced.
