IPC: H01C17/24
Filed: 1990-10-08
Abstract: PURPOSE:To enable precision trimming by attaching a slider to a sliding resistor of a trimming substrate for sliding and by carrying out trimming while detecting a position. CONSTITUTION:A control part 101 designates a rotation angle of a slider 109 to a position detection part 108 and rotates the slider 109 to an electrode position 301. Then, a beam scanner control part 103 is commanded to position a beam scanner optical system 104 to a trimming starting position. The control part commands a laser oscillator 102 and trims a resistor 311 until an aimed value is detected by a resistance measurement part 105 while driving the optical system 104. When a plurality of cuttings are formed to rotation of a slider, an aimed value to a present rotation angle and an aimed value to a rotation angle immediately before are divided proportionally by the cutting number, and the value is used as an aimed value and trimming is carried out by positioning at the proportionally divided trimming starting place.

Abstract: PURPOSE:To improve calibrating accuracy, by storing the maximum value of the internal pressure in a cylinder with negative intake pressure and the number of revolutions of an engine as parameters, and performing calibration based on the comparison with the maximum value of an internal pressure sensor for the cylinder every time the engine is started. CONSTITUTION:The value Pmax of the maximum internal pressure in a cylinder, which is obtained with the number of revolutions of an engine and negative intake pressure at the time of cranking as parameters, is stored in the memory in a control unit 9 in a map form. When the engine is started, the maximum output value Vmax of an internal pressure sensor 2 for the cylinder is detected with a monitoring and detecting means 91 before the initial detonation. At this time, the value Pmax of the internal maximum pressure in the cylinder is obtained from the stored map with a map reference means 92 based on the intake pressure and the number of revolutions of the engine at that time. The operation of Pmax/Vmax is performed with a coefficient setting means 93. Thus the calibrating coefficient of the internal pressure sensor for the cylinder is obtained. In this way, the internal pressure sensor for the cylinder can be automatically tested highly accurately.
