Title: Task preemption controlling system
Inventor: ISHIBASHI EIJI
IPC: G06F15/16
Filed: 1989-08-31
Abstract: PURPOSE:To facilitate a preemption processing by selecting a CPU which is executing a task having the lowest priority and starting a dispatch interruption. CONSTITUTION:The priorities of the tasks which are under execution via the CPU 10-1 to 10-n are set to the 1st register means 31-1 to 31-n for each CPU together with the priority of the task to which a CPU is newly assigned set to a 2nd register means 32 respectively. When the priority is set to the means 32, this set value is compared with the values set to the registers 31-1 to 31-n via a comparison means 34. Based on this compared result, the CPU that is executing the task having the lowest priority is selected by the means 34. Then a dispatch instruction signal is outputted to the selected CPU and this CPU produces a dispatch interruption based on the dispatch instruction signal and performs a preemption processing. Thus the preemption processing is simplified.

Abstract: PROBLEM TO BE SOLVED: To improve the detection accuracy of a soldered part by matching an alignment mark on the side of a single-sided circuit board and an alignment mark on the side of a double-sided circuit board to achieve an accurate detection of the position of the alignment marks. SOLUTION: A model single-sided circuit board having an alignment mark soldered thereon is irradiated previously with X-rays of an X-ray source 1 to store an image into an image memory 4a for one side. In detection, a double- sided circuit board having an alignment mark soldered thereon is irradiated with the X-rays to store the image into an image memory 4b for two sides. More than one alignment marks are carved from the respective X-ray images of the single-sided board and the double-sided board and undergoes a binary coding to obtain correct alignment mark images. A calculator 5 determines the coordinates of the centers of gravity of the respective images from the binary-coded image. Then, both the alignment marks are made to match each other by computing a transformation of coordinate coefficient and a coordinate difference is determined to obtain a differential image.  Thus, alignment mark positions of the single-sided board and the double-sided board can be detected accurately thereby improving the detection accuracy of a soldered part.

Title: Automatic error correcting method for position detector
Inventor: EZUKA YASUHIRO
IPC: G05D3/12
Filed: 1988-09-07
Abstract: PURPOSE:To obtain the correction value after estimating the higher harmonic component and to correct the error between a detected position and an actual position by making use of the amplitude information after converting a 2-phase signal into the polar coordinates. CONSTITUTION:The voltage generated at both ends of each of current detecting resistances 202a-202c are applied to a circuit 210 as the individual phase input. While the joint between an oscillator 201 and a resistance 203 is connected to a reference signal input terminal of the circuit 210. The circuit 210 digitizes a 3-phase carrier signal via an A/D converter and a sampling circuit in order to produce the digital position information. A processing part 220 performs a polar coordinate conversion process to convert a 2-phase signal obtained by a resolver main body 100 into the polar coordinates from the orthogonal coordinates. At the same time, the part 220 estimates a detection error based on the amplitude component after making use of the amplitude information for correction of the error between a detected position and an actual position and carries out an automatic correcting process of an error due to the higher harmonic of the working resolver. In other words, a position detector owns a function to correct the detection accuracy by itself.
