Title: Life detector for smoothing capacitor
Inventor: HARADA KOSUKE
IPC: G01R31/00
Filed: 1986-09-25
Abstract: PURPOSE:To easily discriminate the deterioration of a smoothing capacitor in an operating state by monitoring the ripple current or voltage of the smoothing capacitor and detecting its variation. CONSTITUTION:A current detector 28 extracts the ripple current flowing through the smoothing capacitor 24 and an arithmetic detector 40 converts the ripple current detected by the detector 28 into a voltage signal. Arithmetic amplifiers 42 and 44 input the voltage signal to extract a DC voltage proportional to the amplitude of the ripple current of the capacitor and input the voltage as a necessary voltage level to one input terminal of a comparator 32 through a resistance R1. Consequently, the detector 28 detects the ripple current or voltage without exerting any influence upon the circuit and monitors it all the time. Then the deterioration of the capacitor 24 advances, it is discriminated that the value of the ripple current decreases gradually from the ripple current of a normal capacitor, thereby accurately detecting the life of the capacitor 24 while the capacitor is in the use state.

IPC: G01P3/44
Filed: 1986-09-26
Abstract: PURPOSE:To achieve inspection with a sufficiently high accuracy regardless of a larger sampling interval of a discrete type rotational speed data, by determining the minimum value of rotational speed in an actual continuous rotational speed by estimation. CONSTITUTION:An input changeover switch 4 is connected to an F/V converter 5 and a rotational speed sensor 3. The converter 5 converts a rotational speed signal of an engine 1 into a rotational speed voltage signal to be applied to an A/D converter 7. The converter 7 samples a voltage value at a fixed time interval from this continuous rotational speed signal and converts it into a digital signal to be fed to a central processor 8. The processor 8 determines changes in a rotational speed data from a discrete type signal thus obtained to obtain the minimum value obtained near a explosion start timing of each cylinder from such changes. Thereafter, the actual minimum value is estimated in the rotational speed based on the rotational speed data near the minimum value. A rotation variation is determined from this estimated minimum value to be compared with a reference value for judging acceptance or rejection.
