IPC: G05B19/4093
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a robot control device capable of providing a program development supporting environment excellently handleable for both end user and intermediate user. SOLUTION: A simple programming device 5 for constituting this robot control device 1 reads a simple program database from the side of a robot controller 3 when power is supplied and uses it. At the time of program preparation, a main processing program is read from the side of the robot controller 3, row insertion or the like is performed to it and the correction is performed. A correction operation is performed by utilizing a sub-routine prepared by the intermediate user and registered beforehand on the side of the robot controller 3 by specifying an expansion instruction allocated to it. By using the sub-routine, in the case of using a basic instruction, since a program requiring the description of many rows is described by a few rows, it is convenient.  Also, since the contents of the sub-routine can not be accessed from the side of the simple programming device, an adverse effect that the end user erroneously corrects the contents is not generated.

Filed: 1988-03-28
Abstract: PURPOSE:To realize a method for discriminating all formed parts non-destructively, surely and in a short time by oscillating an ultrasonic wave to a multi-layer formed part, and discriminating whether an intermediate layer is interposed or not, based on an attenuation characteristic of a reflected wave which is detected. CONSTITUTION:An ultrasonic pulse oscillating device 2 transmits an ultrasonic pulse to a multi-layer formed part W through an ultrasonic probe 1, and its reflected wave is received by the probe 1 and inputted to a comparator 4 through a high frequency amplifying circuit 3. In such a state, the comparator 4 sets the input to an ultrasonic pulse of a prescribed reference level and outputs it to a control circuit 6, and the circuit 6 measures rise width of the ultrasonic pulse by the number of pulses of a pulse oscillator 7. Subsequently, this number of pulses is brought to shift register temporarily to a first pulse storage device 8, and shifted to a second pulse storage device 9 from the device 8, when the circuit 6 is counting the next reflected wave. Therefore, by subtracting the number of pulses which is brought to shift register to the devices 8, 9, the attenuation of the reflected wave is detected, and whether an intermediate layer is interposed in a multi-layer formed part W or not is discriminated.

Title: Detecting device for peak position of measurement output

IPC: G01N30/86
Filed: 1986-03-31
Abstract: PURPOSE:To find the accurate time of a peak through a simple arithmetic operation by calculating the point where a straight line connecting difference values of two successive sampling data crossing a time base and deciding the time of the peak point based upon the point. CONSTITUTION:A CPU puts a sampling circuit SP in operation to input the output signal of a detector D to a RAM through an A/D converter and then executes a processing program stored in a ROM. Then, a difference S(0)=H(0)-H(1) is calculated by using the time (t) from the point of sample introduction to the current point of time, a sampling interval DELTAt, current sampling data H(0), and last sampling data H(1). This operation is carried on until the S(0) becomes negative and the peak time P is calculated from an equation. Thus, the difference between the sampling data and a linear conversion expression for the difference are processed to reduce the quantity of necessary arithmetic operation greatly as compared with a quadratic approximation system and the time of the peak point can be found with time accuracy higher than a sampling rate within the ability range of a microprocessor.

Filed: 1981-05-20
Abstract: PURPOSE:To decrease error due to sudden change in electrochemical DC noises in detecting the sudden change in the electrochemical DC noises by outputting the value obtained from the sample value before the detection of the sudden change. CONSTITUTION:An exciting current, which has 1 cycle comprising 4 periods of positive, zero, negative, and zero, is flowed in an exciting coil 1. The output of the differential amplifier 6 is sampled at every period by an A/D converter 8. The digital sampled value is stored in a memory 10. Then a CPU sequentially compares each stored sample value with the sample value 1 step earlier. When the difference is larger than the predetermined value, it is judged that the sudden change in the electrochemical DC noises has occured. Instead of the sample value of the sudden change detection, the amount of variation is added to the sample value before the sudden change detection and outputted. Thus the error due to the sudden change in the electrochemical DC noises can be decreased.
