| PURPOSE: To improve working efficiency of a frequency measuring apparatus by inspecting an input signal to automatically set the measuring apparatus so as to be able to obtain optimum measurement and display. CONSTITUTION: A measuring circuit 111 preprocesses an input signal and stores it in a memory. A microprocessor μP109 controls the measuring circuit 111 according to the selection 107 of a user. In order to perform automatic scaling and to set parameters of the measuring circuit 111 and a display device 103, the center voltage (50% voltage) of input waveform of the display device 103 is first found and made the threshold value which is set to the measuring circuit 111. The maximum and minimum frequency of the input signal is then obtained, and a measuring parameter is set to the value close to the optimum value on the maximum and minimum parameters. A ratio of frequency resolution to a frequency range is measured while changing the selected measuring parameter so as to set the value of the parameter to make the resolution ratio sufficient. The parameter for the display 103 is then set on the basis of the maximum and minimum frequency. COPYRIGHT: (C)1994,JPO | ||||||

| PURPOSE: To obtain a sensibility almost equal to the sensibility of an active sense by integrating a signal from a frequency higher than a prescribed frequency, amplifying and integrating the signal between the frequencies. CONSTITUTION: A standard passive sensor (differential sensor) 10 is connected to the load 12 of a value Rc through the cable 11 of an impedance Rc . The received signal is processed by a device 22 provided with an integration means 20 and a correction means 21. An integration means 20 is especially constituted of a reduction-type cell R2 C2 . In such a case, it often occurs that a time constant τ2 equal to R2 C2 is considerably smaller than a conventional time constant τ1 , and therefore an expression f2 = 1/(2πR2 C2 )}>>f1 is realized. The sensibility of the device becomes larger by f2 /f1 times, a low cut off frequency becomes from f1 to2 and the signal generated from the differential sensor 10 is not integrated by the frequency f1 as the result of integration from the frequency f2 larger than the frequency f1 . Thus, the correction means 21 connected to the integration means 20 makes a specified response and the loss of the response with the low frequency is compensated. | ||||||

Also, in this case, as for the capacitor 23, that which compensates a temperature characteristic and a time aging characteristic, respectively of the battery 10 is used. In such a way, the charge/discharge quantity of the battery can be measured exactly. COPYRIGHT: (C)1989,JPO&Japio | ||||||

| The invention relates to a method which can be used, in particular, in radiometric weighing devices and for the radiometric determination of density. Whereas the aim of the invention consists in reducing the expenditure and in the improved use of the radiator activity, it is the object of the invention to use digital computing technology to linearise the attenuation curves over the entire range of the intensity of radiation. According to the invention, all the pulses which leave a specific detector in a selectable time unit are counted and the pulse numbers are assigned specific mass elements or pseudo-masses. The mass elements and pseudo-masses are corrected in a fine linearisation and supplemented to form a linear dependence of the attenuation of the nuclear radiation on the transirradiated mass. | ||||||

| PURPOSE:To make reading of a voltmeter more adequate by connecting a constant voltage element in series to a DC voltmeter and applying the voltage of a voltage source to be measured to the series circuit thereof. CONSTITUTION:If, for example, a DC voltmeter 1 is assumed to be a voltmeter of 0-9V, a Zener diode 2 has 9V breakdown voltage, and a variable power source 3 is assumed to be 0-18V, and when the voltage of the source 3 is between 0-9V, the voltmeter 1 indicates 0 and when said voltage is 9-18V, the voltmeter 1 indicates 0-9V according to the voltage of the source 3. If at this time the scale of the voltmeter 1 is marked as 9-18V, the voltage can be read between 9-18V with twice higher precision than that when the voltage is marked with 18V. Thus the pointer of the voltmeter is enlarged and the reading of the voltmeter is made more adequate. | ||||||

| PURPOSE: To continuously perform a positive and negative nonlinear correction by a method wherein a sensing element converting a measured quantity into an electric signal is excited in proportion to a reference voltage to be obtained from the difference voltage between a variable voltage dividing point and a fixed voltage dividing point. CONSTITUTION: The output of a bridge circuit 20 having sensing elements R g1WR g4 converting a pressure et al into an electric signal is transferred to a receiving resistor 6 through a voltage/current converter 1. And further, a part of an output voltage is fed back to dividing resistors R 01, R 02 and a constant voltage V z is fixedly divided and along with this, the variable voltage dividing circuit is formed from a variable resistor R x and from the difference voltage of these, a reference voltage VR is obtained, thus, the bridge circuit 20 is controlled so as to be proportional to the reference voltage VR. As a result, the relation between an output current and the pressure can be made an approximate linear state by setting the variable resistor RX properly. Thus, with a simple structure, positive and negative nonlinea correction can be made smoothly. COPYRIGHT: (C)1981,JPO&Japio | ||||||
