Title: Overcurrent detecting method of inverter
Inventor: KIMURA ARATA
IPC: H02H7/122
Filed: 1983-06-29
Abstract: PURPOSE:To enable to detect an overcurrent at a high speed by discriminating the overcurrent by the current flowed to a current limiting reactor. CONSTITUTION:A load current is flowed to a diode 52 when an OFF signal is applied to a GTO50. A current of a current limiting reactor 3 is circulated through a diode 4, and a main circuit current is zero at this time. When GTOs 51 of paired arms are then turned ON, a current of the direction for cancelling the current of a diode 52 is flowed from a DC power source 1. Further, when the diode 42 is recovered by a reverse current, a main circuit current is moved to a route for charging a snubber capacitor 58 of the GTO50. After the capacitor 58 of the GTO50 reaches a power source voltage, only the GTO51 becomes conductive state. The current flowed to the reactor 3 is detected by a current detector 8, compared with the set value by a comparator 9, thereby discriminating the overcurrent.

Abstract: PURPOSE:To securely detect a minute flaw, as well by switching a slide level by two stages in real time corresponding to the conductor pattern part and clearance part of a circuit board being a body to be inspected. CONSTITUTION:Slide level generators 22a and 22b generate a slide level V1 a little bit higher than the normal signal level of the conductor pattern and a slide level V2 a little bit lower than the normal signal level of the clearance part and apply them to comparators 24a and 24b respectively. Normal image data on a circuit board which is not to be inspected are written previously in a template pattern memory 36 for pattern matching. Then an image signal from a camera 10 is compared by the comparators 24a and 24b with the slide levels V1 and V2 and converted into binarization data. One of those binarization data is selected according to an inspection place by controlling a switch circuit 32 with readout data from the pattern memory 36 and supplied to a serial/ parallel converter 26.

Abstract: PURPOSE:To immediately change the robot actions in response to the change of an external state by preventing the discontinuous velocity changes of a nonlinear feedback loop to each axis at the time of changing a parameter. CONSTITUTION:In a PTP motion where a middle route of a biaxial robot is not designated, the uniaxial acceleration/deceleration generating algorithm is given to each axis together with a synthetic acceleration distance CDa and a synthetic deceleration distance CDd obtained in a joint space and furthermore a synthetic steady velocity CV of the steady velocities of the 1st and 2nd axes respectively. Then the acceleration distances Da1 and 2, the deceleration distances Dd1 and 2, and the steady velocities V1 and 2 of the 1st and 2nd axes are calculated by the equations I and II based on the target values X1 and X2, and the present positions x1 and x2 of both axes respectively. Thus a fixed parameter is given to each axis parameter updating algorithm and the target value of an acceleration/deceleration curve can be changed at an optional time point. Then the velocity continuity of each axis is individually assured and therefore assured even with the biaxial robot.

Abstract: PURPOSE:To keep a car pitching properly during driving at adjustable speed as well as to make a car body go back to horizontality after shifting to driving at constant speed, by holding a level-control signal to the level-control signal that is to be transmitted to a level-control unit in case of the constant speed driving. CONSTITUTION:A level-control sensor 24, consisting of a front right-left and rear right-left sensors 20-23, detects each car level at both sides. A fuel injection sensor 26 is possible to detect a fuel injection quantity increment DELTATf as an adjustable speed value at an accelerating sensor detecting an adjustable speed driving state. A controlling device 46, which transmits a level-control signal to a level-control unit 41 on the basis of each signal out of these sensors 24 and 26, is installed. In the case where a difference between level-control values of the sensor 24 is more than the specified value and the sensor 26 is also more than the specified value, the level-control signal to be transmitted to the unit 41 is made to be held on the level-control signal that is transmitted to the unit 41 in case of driving at constant speed. With this constitution, pitching takes place properly during a drive at adjustable speed.
