摘要： An apparatus for detecting flaws using supersonic waves measures a thickness of a test object or a position of a cavity inside the test object by employing a pair of ultrasonic probes. By, changing a relative position of one ultrasonic probe to that of the other ultrasonic probe, a plurality of waveform data of ultrasonic reception signals is acquired. Each of the acquired waveform data is added together. Because a surface wave component of each waveform data has a shifted phase due to a difference in arrival times, a level of the surface wave component is offset and thus minimized through addition of the waveform data.

摘要： When a control section of a data carrier discriminates a command from a reader/writer, either one of two kinds of pseudo random signals is returned in accordance with a bit 0 or 1 of response data. When two autocorrelation values obtained by correlation arithmetic operations are simultaneously equal to or greater than a predetermined threshold value, the reader/writer determines that a communication has been executed with two or more data carriers, so that an error warning, an access stop, a retry, or the like is executed. The reader/writer compares the autocorrelation peak value obtained from the pseudo random signal from the data carrier with a threshold value. When it is equal to or greater than the threshold value, the reading operation is executed. In the reading operation of continuous data bits from the data carrier, the reader/writer selects the minimum value from among the autocorrelation peak values of the bits obtained by the correlation arithmetic operations and stores the selected minimum value. When the minimum memory value is smaller than a threshold value, it is determined that data could not correctly be read, so that an error is indicated.

摘要： An instruction point is movably provided in a three-dimensional space and can be freely moved by a finger tip of an operator. When the operator moves the instruction point to a desired position in the three-dimensional space and selects an arbitrary point, a three-dimensional position of the instruction point is measured and is input to a three-dimensional input apparatus. An image object is displayed in the three-dimensional space on the basis of image object information which has been previously stored. A check is made to determine whether or not the instruction point is virtually in contact with the virtual object in the three-dimensional space on the basis of the virtual object information and the position information of the instruction point. If it is determined that the instruction point is in contact with the image object, by limiting the mobility of the instruction point, a drag due to the contact with the virtual object is fed back, so that the operator can actually feel the existence of the virtual object.

摘要： A gyro compass having a gyro case housing therein a gyro and supported with freedom of three axes, functions for outputting a signal corresponding to an inclined angle of the gyro spin axis relative to the horizontal plane, and a function for applying a torque around a vertical axis of the gyro case in proportion to an input signal. A controller is supplied with a signal corresponding to the inclined angle and a latitude value at which the gyro compass is located, and a constant relative to the input latitude value is determined by the controller after the gyro compass is energized. A signal, resulting from differentiating the signal corresponding to the inclined angle during a predetermined time, is added to the product of the signal corresponding to the inclined angle and the constant. This added signal functions as the input signal for the gyro, whereby a constant optimum north-seeking movement is carried out regardless of the change of the latitude value. An error corrector is provided having supplied to it the signal corresponding to the inclined angle, the speed signal of the vehicle and its heading azimuth signal, and a bias error caused by the inclined angle of the gyro compass spin axis and an azimuth error caused by the movement of the vehicle are estimated and calculated to thereby reduce an azimuth error caused by any bias error and the vehicles' movement.

摘要： A distance between a radiation source and a detector is first set to a first distance and the number of pulses of a .gamma.-ray is detected. Then, the distance between the radiation source and the detector is set to a second distance different from the first distance and the number of .gamma.-ray pulses is detected. A density .rho. of a sample is finally calculated on the basis of a ratio of the two detection pulse numbers which were detected. The radiation source is set on the surface of the sample or in the sample. The sample detector is set on the sample surface. Fundamentally, one radiation source and two detectors are used. In the case of using one radiation source and one detector, either one of them is moved and the number of pulses is detected twice.
