  • Patent number: 6102826
    Abstract: A plurality of shift control valves for independently controlling the supply of hydraulic oil to, and the discharge thereof from, a plurality of hydraulic engaging elements are divided into a first group of shift control valves which establish a predetermined-speed transmission train and a second group of shift control valves corresponding to the other hydraulic engaging elements. A fail-safe valve is interposed between an oil supply passage which is connected to a hydraulic pressure source and the second group of speed change control valves. The fail-safe valve is switched to a closed position in a condition in which the hydraulic oil is supplied to all of such plurality of hydraulic engaging elements as are not to be engaged at the same time, whereby the oil supply passage is connected only to the first group of shift control valves. Each of the first group of shift control valves is provided with an oil chamber for urging it toward an oil supply position.

  • Patent number: 5753935
    Abstract: In a radiation detection device using superconducting tunnel junctions, the increase in electric capacitance and the decrease in electric resistance due to the increase in junction area for improvement of the detection efficiency are largely repressed by the invention. The junctions are connected in series. The number of the series-connected junctions is settled in the range of larger than 0.05 (SC.sub.o /C')0.5 and smaller than 20 (SC.sub.o /C')0.5 or 10SCo/C', whichever is larger, where S is the total area of the junctions, cm.sup.2, C.sub.o is the electric capacitance per unit area of the junctions, F/cm.sup.2, and C' is the electric capacitance connected to the device in parallel so as to transfer and amplify the signals from the device, F.

  • Patent number: 5504317
    Abstract: In an optical reader a lens system is located between a source of light designed to illuminate an object to be read and the object. The lens system is designed to refract and diffuse the light produced by the light source to reduce the deleterious effect of specular light reflected from the illuminated object into the optical reader and an image sensor designed to convert reflected photo signals into electric analog signals. In one embodiment of the invention the optical reader includes an array of LEDs and a lens having prisms located in front of each LED for refracting or bending the light output of each LED to reduce the generation of specular light being reflected. In another embodiment the optical reader includes a lens with a light shield strip to prevent the generation of specular light.

  • Patent number: 5394481
    Abstract: A method of inspecting a liquid crystal panel and determining the type of defect. Each part of the liquid crystal panel is extracted and inspected by comparison with an extracted reference part. The parts to be inspected may be found based on the location of previously found parts or by examining a plot of the density in the image. Vector data from a part that is known to be defectless is used to extract the reference part. Alternatively, the contour of a reference part may be determined by analyzing the vector data which was obtained for the parts to be inspected. The type of defect is determined by classifying the defective part according to characteristics of the part's image (e.g., brightness of the pixels) as compared with parts having known defects.

  • Patent number: 5347624
    Abstract: A graphic display method and apparatus including a plurality of virtual device coordinate systems independent of a coordinate system of a physical screen in which a graphic image to be displayed is independently drawn in a virtual device space of the corresponding virtual device coordinate system so as to map a specified area of each virtual device space onto the virtual screen at a specified position, thereby displaying a specified area of a virtual memory in a physical screen. Furthermore, code data of characters and graphics and image data are written in a logical screen buffer as drawing elements to be located at arbitrary positions of the logical screen such that a unit, specifying an area which is located at an arbitrary position and which has an arbitrary size in the logical screen causes the combining and editing of character, graphic, and image data already written in the specified area of the logical screen and the generating, as a result, of new image data.

  • Patent number: 5339093
    Abstract: The present invention makes it possible for unskilled to inspect the total surface of a liquid crystal panel accurately in short time. It is defined that a liquid crystal panel can be divided into a single part which is a constituent, isolable, and an inspectable area, and that the single part to be "unit area of image" which is defined as a pattern to be inspected. Before the inspection, a unit area of an image without defect is selected from a liquid crystal panel to be inspected. The upper limit reference pattern and the lower limit reference pattern are generated by giving the maximal brightness in a convolution and adding the predetermined brightness and by giving the minimal brightness in the convolution and subtracting the predetermined brightness, respectively, to each pixel of the convolution.

  • Patent number: 5321276
    Abstract: A superconducting tunnel junction radiation sensing device includes first and second superconductor electrodes and a tunnel barrier layer interposed therebetween. The tunnel barrier layer is made up of a thin-wall portion and a thick-wall portion each formed of a semiconductor or an insulator, and each having opposite surfaces respectively contacting the first and second superconductor electrodes, and each extending adjacent each other in a same horizontal plane between the first and second electrodes. The thick-wall portion has a vertical thickness which is at least twice that of the thin-wall portion. Furthermore, the thickness of the thin-wall portion is such that a tunnel effect is enabled therethrough form the first electrode to the second electrode, and the thickness of the thick-wall portion is such that a tunnel effect is substantially prohibited therethrough from the first electrode to the second electrode.

  • Patent number: 5321769
    Abstract: It is possible to inspect a printed matter precisely because lines are surely and accurately extracted by the present invention. Extraction of lines are the important point for the judgment if a character is correctly printed or not. The printed matter inspection method according to the present invention comprises the following steps: i) an image of a predetermined area including a line is input; ii) a density projection is performed on said input image; iii) a start point and end point of change of density are emphasized in said density projection; iv) the center pixel in each predetermined convolution is substituted by the minimal density pixel in each said convolution; v) a density projection is performed; and vi) said printed matter defective or not is judged according to said density projection in v).
