Title: Editing controller for video tape recorder
Inventor: TOKUYAMA MITSURU
IPC: H04N5/7826
Filed: 1990-04-19
Abstract: PURPOSE:To obtain an editing controller which controls editing like film editing by recording and holding a video signal for a certain time and always simultaneously monitoring pictures preceding and following the current picture. CONSTITUTION:The picture of a VTR source input to which an editing point should be set is read out from a video signal storage part 5 by a control part 1 and several frames are simultaneously displayed on a display part 2 in the same manner as a movide film. In this case, the picture in the center of the display screen corresponds to the input of the source VTR in 1:1, and the editing point is set there. A storage video time T(n) and a time code TC(n) are stored in relations of 1:1, and for example, TC(n-1) is a dummy actual time, and the picture is changed to change the dummy actual time. Consequently, an editor can set the editing point without paying his attention to the time code while relating preceding and following pictures to each other.

Abstract: PURPOSE:To cover the deterioration in the capacity of reducing the thickness caused by the deterioration of an acid soln. and to permit automatizing treatment by measuring the deviation of the inside diameter of a pipe and the speed of reducing the thickness in the process of flowing and independently controlling the soln. passing time. CONSTITUTION:As for the control of the inside diameter of a zircaloy pipe by an acid soln., a soln. of nitric-hydrofluoric acid of 30 to 40% HNO3+1 to 2% HF is used. In advance, the inside diameter of the pipe P is measured by an inside diameter sensor 10, and after that, it is fitted to a head 40. Then, while the thickness of the pipe P is measured by an ultrasonic thickness gauge, an acid soln. is passed through the inside diameter of the pipe P. From the data therefrom, the capacity of reducing the thickness=the amt. of the thickness to be reduced/the soln. passing time has been calculated. New four pipes P in which the measurement of the inside diameter has been finished are set to a treating position No. 1 and the output is controlled so that the soln. passing time will be regulated to the one calculated by the soln. passing time=(the measured value of the inside diameter-the objective inside diameter)/2Xthe capacity of reducing the thickness. This treatment is successively repeated, by which the control of the inside diameter with high accuracy is enabled.

Title: Apparatus for detecting displacement of weight
Inventor: OZAWA HIROMASA
IPC: G01P15/093
Filed: 1985-05-16
Abstract: PURPOSE:To detect the displacement of a weight with high accuracy, by fixing an optical fiber to a fixing part and making it possible to directly detect the movement of the optical fiber due to the displacement of the weight by acceleration. CONSTITUTION:The light from a light source 13 is reflected by a reflector 14 through a first optical fiber 11a and received by a light receiving part 15 through a second optical fiber 11b. Then, the light receiving part 15 is brought to a continuity and both terminals 20, 25 become almost equal in potential and potential difference is generated between both terminals of a resistor 24, that is, in a voltmeter 26. However, when acceleration of a definite value or more acts on a horizontal surface, the displacement quantity of a weight 12 becomes large and the curve of the optical fibers 11a, 11b becomes large while the light from the light source 13 passes through the optical fiber 11a to be reflected to a different direction by a light reflector 14 and no reflected light is incident to the optical fiber 11b and, therefore, no light reaches the light- receiving part 15 and the light receiving part 15 comes to a discontinuity and no potential difference is generated in the voltmeter 26. Therefore, when the potentials at both terminals of the voltmeter 26 become equal, it can be detected that the value equal to or more than acceleration predetermined at every direction has acted.

IPC: H04N7/18
Filed: 1995-04-28
Abstract: PURPOSE: To automatically control the brightness of a radioscopic image of an interest part in a proper value, and enhance diagnostic capacity of the interest part by restraining an excessive video signal by direct incidence of X-rays, and forming it as a video signal of a specific level. CONSTITUTION: X rays are applied to an examinee 3, and an X-ray transmitted image passing through this becomes a visible image by an image intensifier 4. However, in a slender examinee, an excessive video signal is outputted to a part on which X-rays are directly made incident. A limiter circuit 12 restricts the excessive video signal not less than a prescribed level by direct incidence of X-rays, and formed it as a video signal of a specific level. Then, after calculating an average value of video signal intensity by an averaging circuit 8, tube voltage and a tube electric current are controlled by an automatic brightness adjusting circuit 9 so as to coincide with a reference signal.  Therefore, even if X-rays are directly made incident, brightness of a radioscopic image of an interest part can be automatically controlled in a proper value, and an interest area image is made easy to see, and an X-ray television whose diagnostic capacity is improved can be obtained.
