Abstract: PROBLEM TO BE SOLVED: To reduce an erroneous correspondence rate by extracting correspondent points, for which the phase difference of correspondent points extracted on mutually different conditions is mutually equal, from the correspondent points of a stereo image as matched correspondent points and removing the picture elements of erroneous correspondence out of the correspondent points. SOLUTION: A correspondent point search part 14 extracts the picture elements, which become the correspondent points, from the stereo image on conditions 1 by comparing them with a feature value. On the conditions 1, the correspondent points of phase difference are extracted inside the range of an object, and the correspondent points are extracted in the areas on the right side and downside of the image. The correspondent point search part 14 extracts the picture elements to become the correspondent points from the stereo image on conditions 2. On the conditions 2, the correspondent points are extracted in the areas on the upper left side and the down side in addition to the correspondent points.  Among the correspondent points in the left image extracted on both the conditions, the correspondent points of the equal phase difference on both the conditions are extracted as the matched correspondent points by a left matched correspondent point extraction part 26. Among the correspondent points in the right image, the correspondent points of equal phase difference on both the conditions are extracted as the matched correspondent points by a right matched correspondent point extraction part 28.

Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To reduce parasitic resistance and parasitic capacitance, and to prevent a malfunction at high speed by forming a second side-wall insulating film on the side wall section of an inter-layer insulating film so as to cover the exposed surface of a gate electrode together with the inter-layer film. SOLUTION: The contact holes 15 of a source and a drain are formed in a self-alignment manner to a gate electrode 5, and side wall films 17 in proper film thickness are formed on the side sections of the contact holes 15 so as to be brought into contact with the side wall films 9 of the gate electrode 5. The film thickness of the side wall films 17 formed after the contact holes 15 are bored and the film thickness of the side wall films 9 are designed properly larger than alignment allowance at that time. Accordingly, parasitic resistance and parasitic capacitance can be reduced, and a semiconductor device having high performance at high speed can be acquired. Since a high melting-point metallic silicide layer 12c having low resistance is formed onto the gate electrode 5, gate resistance can be lowered, and operation at higher speed can be conducted.

Abstract: PURPOSE:To heat treat a work by an abrupt temperature curve by disposing high temperature holders at upper parts of an entrance passage and a delivery passage, and providing elevating means for moving the work. CONSTITUTION:A high temperature holder 24 is disposed above an entrance passage 23 and a delivery passage 27, and a temperature rising part 23 is composed of elevating means 23 for moving a work 21 from the passage 23 to the holder 24 and an elevating means 30 for moving the work 21 from the holder 24 to the passage 23. Thus, the conveyed work 21 is raised at the part 23 to the holder 24, burned by the holder 24, and then lowered at a temperature falling part 25, and hence a temperature setting in a conveying passage 28 is effective, and an abrupt temperature gradient can be obtained at the parts 23 and 25 at the holder 24 as a boundary. Further, since the holder 24 is disposed above, a heat output of the holder 24 in the passage 28 particularly scarcely occur to prevent loss of thermal energy and to facilitate control of an atmosphere.

Filed: 1989-03-13
Abstract: PURPOSE:To reduce the load of a cutter and to obtain a satisfactory cut surface by reducing the working speed at a point where the curvature radius is small for an involute curve formed near a basic circle. CONSTITUTION:A tape reader 2 reads a tape 1 where the commands are punched, and a pre-processing means 3 judges the presence or absence of an involute interpolation command. An involute interpolation data origination means 4 originates the data necessary for the involute interpolation from the command value. At the same time, a curvature radius is calculated and the override value is obtained when the curvature radius is smaller than the fixed value. The interpolating speed is reduced according to the override value. A pulse distribution means 5 obtains each point of an involute curve from the data originated by the means 4 and performs the interpolation to distribute pulses. A servo control circuit 6 drives a servo motor 7 with a command, and the motor 7 moves a machine 8 via a ball screw, etc. Thus a satisfactory cut surface is obtained.

Abstract: PURPOSE:To emphasize the contour of color to a carrier chrominance signal and to decrease the spreading of color in a reproduced picture by supplying an output signal from a differentiator, which differentiates an output signal from a filter, as a gain control signal to a variable gain amplifier. CONSTITUTION:A low-pass filter LPF 5 has a zero point in a frequency 2sc and has a filter characteristic to attenuate more than a central frequency fsc. In a differentiator 6, only a contour part is extracted by differentiating the output signal of the LPF 5 and taken out as a signal only in the starting part and ending part of a burst waveform. The output signal of this differentiator 6 is supplied as the gain control signal to the input end of again control. Thus, the gain of a variable gain amplifier 2 is made high in the starting part of the burst waveform, reversely made low in the ending part and fixed in the other part. Accordingly, in the variable gain amplifier 2, the contour part of the carrier chrominance signal can be emphasized and the spreading of the color can be decreased.
