摘要： PURPOSE:To measure the pulse period under the optimum interpulse distance at all times by frequency dividing the output pulse of the speed detector or a chassis- dynamometer corresponding to its detection speed. CONSTITUTION:The output of pulse of speed detector provided in a chassis-dinamometer is sent to frequency counter 3, which counts the pulses of clock pulse generator 4, via frequency divider 2. The measured frequency is supplied to frequency-division-ratio switch 51 and speed comparator 52, and it is compared with the preset value of period. Frequency-division-ratio switch 51 selects a frequency- division ratio and sets it in frequency divider 2. Speed comparator 52 sends the coinciding output to time meter 6. Consequently, since it is possible to automatically frequency- divide the output pulse of speed detector 1 by the optimum frequency- division ratio determined by its detected speed, it is possible to eliminate variation in the measured value of pulse frequency at the time of high speed operation and thereby to improve measuring precision.

摘要： PURPOSE:To completely compensate the output of displacement meters as to temperature, by determining the ratio of the output difference between both the displacement meters facing each other across a displaced piece, to a weighted value resulting from the addition of a prescribed offset value to the sum of the outputs of the displacement meters. CONSTITUTION:Displacement meters 1, 2 are so placed that they face each other across a displaced piece 3. It is supposed that the displacement meters 1, 2 produce output voltage V1, V2 as to a certain displacement of the piece 3 from the middle point of both the displacement meters 1, 2 as a reference. Although the difference between the output voltages V1, V2 has only one temperature term and the linearity between the difference and the displacement of the piece 3 is high, the influence of temperature is not eliminated. The sum of both the output voltages is constant to the displacement because the voltages have inverse polarity to each other. As for the ratio of (V1-V2)/(V1+V2), the temperature term is represented in the form of a ratio and the influence of temperature is reduced. To remove the temperature term, the difference V1-V2 is divided by a weighted value resulting from the addition of a prescribed offset voltage to the sum V1+V2. The influence of temperature is thus completely eliminated.

摘要： PURPOSE:To enable to detect the position of joints as the electric output simply by using the cross sensor. CONSTITUTION:The cross sensor 1 is orthogonal to the exciting core 10 of U-shape and the detection core 20 each other, the legs 11 and 12 of the excitation core 10 are wound for the excitation coil 13 additionally, and the legs 21, 22 of the detection core 20 are wound differentially for the detection coil 23. The cross sensor 1 has opposing angle of 45 deg. to the welded joint 31 of the welded member 30, and the legs 11, 12, 21, 22 are held at the holding tool in the suitable distance each other. The DC bias magnetic field Hdc is applied from the direction orthogonal to the welded joint 31 to the welded member 30. As a result, the welded member 30 is in the range of high magnetic field and noise component due to the irregularity and ununiformity of heat treatment can be minimized.

摘要： PURPOSE:To further enhance the automatic compensating accuracy of the lost load of a dinamometer device by always detecting the varying causes of the lost load so that the variations in the lost load are automatically compensated. CONSTITUTION:The temperature and pressure at the respective portions, which cause the lost load to vary, are always detected. If the variations exceed the allowable value, a change-over circuit 40 generates its output thereby to effect an automatic change to the drive or absorption at a preset current of the motor. Similarly to the detection, in which automatic control is performed upon the temperature and pressure within a preset range, the calculations are performed in a calculation memory unit 22, and the detected values are memorized in a preset address. These values are compared with the memorized detected values so that either of the previous detected values and the target load to be controlled are compensated. Thus, it is possible to further enhance the automatic compensating accuracy.
