Abstract: PURPOSE:To prevent accidents by using the results of judgement and management of time range, by a managing means of transmission time range, where operational values of a plant are changed based upon operational cycle data and standard timing signals which are output from a generating measures of standard timing. CONSTITUTION:A managing part 16 of transmission time decides transmittable time range where operational values of a plant 9 can be changed and untransmittable time range where changing of the operational values is prohibitted, by using standard timing signals for starting an input operational cycle, and operational cycle data, and also informs the changing over timing of the two time ranges to a transmission controlling part 17 of the operational values.

Abstract: PURPOSE:To form a single-crystal thin film without crystal defects on an insulating film by a method wherein the surface of the insulating film is made lower than a substrate single-crystal region which is to be a seed and the gentle transition of substance from the substrate to the insulating film is provided. CONSTITUTION:An SiO2 film 10, an Si3N4 film 11 and a resist film 12 are formed on a region to be a seed of single-crystal growth. After a substrate Si 9 is etched into a slope by unisotropic etchant such as hydrazine, the resist film 12 is removed. Then the whole surface is oxidized and an SiO2 film 12 and an Si3N4 film 13 are formed. The Si3N4 is subjected to unisotropic etching such as reactive sputtering. In this process, the Si3N4 film is removed completely except the sloped part so that the Si3N4 film 11 on the seed and the Si3N4 film 13 on the sloped region are left as the Si3N4 film. When the substrate is subjected to oxidization in this state, as the Si3N4 films work as a mask, the thickness of the SiO2 film is varied on the sloped region so that an SiO2 film 14 which has different thickness at the end part is formed. Then the SiO2 films 10, 12 and the Si3N4 films 11, 13 are removed. A polycrystalline Si film 15 is deposited and then scanned to the direction of an arrow 17 by a laser light 16.

It computes the interval between position detections with a position detection interval computer 10b separately for each position detection of a brushless motor, and computes a single cycle with a cycle computer 10c by this interval between position detections, and computes the present number of revolutions with a revolution computer 10d by this computed cycle, and determines which of the above plural number-of-revolutions regions this computed number of revolutions is in with a number-of-revolutions region determiner 10e, and decides the data corresponding to this determined number-of-revolutions region,  with a current application switching time determinator 10g, referring to the storage 10f, and sets this determined data in a conveyor register part 10h. When the count value from the above position detection conforms to the contents of the conveyor register part 10h by a timer controller 10i, it switches the current application of the brushless motor 4 by a current application switch 10j.
