Abstract: PURPOSE:To prevent the deformation of a reinforcement and the inclination of an end mould by providing plural pressure jacks to operate separately from the end mould and to apply a pressure to the concrete placed between the end mould and an inside mould, to the end mould. CONSTITUTION:After an excavation is finished, a propelling jack 5 is contracted to withdraw one end-mould 3a to the position a reinforcement 6 is assembled, to a facing side. Then a joint reinforcement 10 is inserted to a joint reinforcement insertion port 11 provided at the end mould 3a, and the reinforcement 6 is assembled. And after an inside mould 8 is assembled by using an erecter 7, the jack 5 is extended to fix the end mould 3a to the inside mould 8. The same works are repeated to other end-moulds, and the inside mould 8 and the jack 5 are expanded every time. Furthermore, after a concrete 13 is placed inside the mould, the pressure of the concrete 13 is detected by a pressure gauge, and a desired concrete pressure jack 4 is extended or constracted to apply or reduce the pressure until the concrete 13 gets a specific pressure.

Title: Video camera
Inventor: USUI TAKABUMI
IPC: H04N5/243
Filed: 1990-07-12
Abstract: PURPOSE:To suppress the degradation in S/N of a video signal in the low- illuminance area of an object by providing a maximum gain variable control means and raising the maximum gain of an automatic gain control means at the time of reduction of the illuminance of the object. CONSTITUTION:When the illuminance of the object is low and the amplitude of the video signal outputted from an image pickup means is shorter than a preliminarily determined level, a maximum gain variable control means 22 limits the maximum value of the gain of an automatic gain control means 14. This maximum value can be changed as the function of the amplitude of the video signal in accordance with this amplitude. Therefore, it is most suitably determined in accordance with the illuminance of the object whether the gain of the automatic gain control means 14 is suppressed to give importance to S/N of the video signal or the gain is raised to obtain a higher output level. For example, the gain of the automatic gain control means 14 can be changed so that the upper limit of the gain is raised when the video signal level outputted from a AGC circuit 12 is reduced. Thus, the degradation in S/N of the video signal in the low-illuminance area is suppressed without degrading the minimum object illuminance.

Abstract: PURPOSE:To narrow a measurable plate width significantly, by arranging displacement meters at a specified interval divided in the ongoing direction and across the width of material to be measured to determine the flatness from a difference between detection values as obtained when the displacement meters face a portion of a surface to be measured on the same line across the width thereof. CONSTITUTION:A plate width set with a width gauge 22 is inputted into a control processing section 25 and displacement meters are selected corresponding to the plate width from among those 13-17 on first and second trucks 9 and 10 to be positioned at specified points. For example, in a steel plate with the min. width, a central displacement meter 14 on the first truck 9 and displacement meters 16 and 17 on the second truck 10 are selected and the displacement meter 14 is positioned at the center across the width while the displacement meters 16 and 17 are positioned so as to be l0 in the interval therebetween. In this case, a measurable min. plate width W0 is given by W0=2l1+l0 and becomes narrower by l0 as compared with the conventional apparatus. Detection outputs are outputted to a counter 24 with a control processing section 25 as obtained when the displacement meters 14, 16 and 17 face a portion of a surface to be measured on the same straight line across the width thereof.

IPC: G01B11/02
Filed: 1986-08-07
Abstract: PURPOSE:To correct line width by scanning a light spot with a constant diameter on a pattern at a constant speed, and calculating the scanning direction and the angle of the pattern from variation in the output of a photodetector with time at an edge part of the pattern. CONSTITUTION:Laser light is scanned on the pattern 47 at the speed (v) to form the light spot with the diameter D, and its reflected light is detected by a photoelectric element. The scanning direction is set at right angles to the pattern 47 first and then while the light spot moves from a state where the pattern 47 is circumscribed to a state where the pattern is inscribed, the output of the photoelectric element varies from a point 13 of a waveform 11 to a point 14. The time required for the movement is denotes as S. Then when the scanning direction slant at an angle theta to the pattern 47, the distance from the state 31 where the light spot is circumscribed with the pattern 47 to the inscribed state 32 is D/sintheta and when the time of the movement from a point 15 of a waveform 12 to a point 16 is S', the tilt angle theta is found from theta=sin(S/S '). For the purpose, a threshold value is set to 1/2 and line width l'.v is multiplied by sintheta to find the accurate line width (l) after the angle theta is corrected.
