摘要： PROBLEM TO BE SOLVED: To perform control more accurately and stably by improving inverter properties for a variable speed driver which is used for the variable speed drive of a heavy rotary machine. SOLUTION: An inverter controller, which is equipped with a speed control part 22, a slip control part 23, an addition part 24, and a frequency limit part 2, is used. The speed control part 22 outputs a torque command T2*, based on the number-of-revolutions command fr2 and the detected number of revolutions fr2 concerned with an AC motor 11 which is speed-variably driven. The slip control part 23 outputs a slip frequency fs*, based on the torque command T2*. The addition part 24 outputs an inverter frequency command fe*, based on the slip frequency command fs* and the detected number of revolutions fr2. A frequency limit part 2 outputs an inverter frequency command fe* if the inverter frequency command fe* is settled in the tolerable frequency, and modifies the frequency nearest to the inverter frequency command fe* and outputs it as an inverter frequency command fe* if it is not settled.

摘要： PROBLEM TO BE SOLVED: To provide an inverter unit capable of providing an AC output having an accurately stabilized frequency regardless of any process cycle of a system control by a processor, having no degradation of frequency-control accuracy even when accelerating or decelerating. SOLUTION: The inverter unit, which contains a power-inverter circuit (4) that converts a fed DC to an AC having a predetermined frequency (fo) and variably drives a rotating-machine motor (11) wherein a switching control of the power inverter unit (4) is conducted by a digital processor (30), is mainly characterized in that a timer-offering process, which has a certain process cycle (Ts) not directly relating to process cycles (Te1, Tc2...) in the digital processor (30), is set, and right and wrong of a timing about the switching control of the power inverter circuit (4) is discriminated while the timer-offering process is ongoing, and then the inverter-output frequency (fo) is controlled.

摘要： PROBLEM TO BE SOLVED: To individually discriminate the type of a vehicle during the travel of the vehicle and to judge the propriety of entrance into the parking lot facility of a mechanical movement type. SOLUTION: A vehicle discrimination device 11 detects the length, the whole height, the shaft distance and the minimum ground height of a front overhang and the length and the whole length of a rear overhung by a width direction detection means and area sensors 31 and 41 during the travel of the vehicle 1. It surely discriminates that the vehicle can be transferred among a lift, a carriage and a storage case before a driver gets off from the vehicle 1 in an entrance position even if the vehicle is any type and the vehicle 1 is altered without stopping the vehicle.

摘要： PROBLEM TO BE SOLVED: To easily evaluate machining accuracy regarding the position and attitude of a cell guide without using any mockup by providing a reflection prism that travels along each cell guide and measuring the three-dimensional coordinates values of the reflection prism at a plurality of positions along the cell guide. SOLUTION: A prism-traveling truck 51 with a reflection prism 5a moves along each cell guide, measures the three-dimensional coordinates values through the reflection prism 5a by a three-dimensional coordinates measuring instrument 52, and at the same time sends the measured coordinates value information to a data-recording device 6. The reflection prism 5a can change an angle by rotation in a direction with a rotary shaft 511a and a pivoting shaft 511b of a holder 511 as a center. The prism-traveling truck 51 can retain a specific position with the cell guide due to the magnetic force of a magnet 514. The measuring instrument 52 rotates freely in a horizontal surface, and the reflection prism 5a can be visually recognized even if it is mounted to any cell guide to be evaluated, thus successively measuring the three-dimensional coordinates value.

摘要： PROBLEM TO BE SOLVED: To accurately measure the quantity of remaining coal in a coal preservatory at a mass-base. SOLUTION: An light wave sending-receiving apparatus 1 is arranged in a coal preservatory, and the height of a storing layer of a coal 3 is measured through the transmission of a light pulse 2 and the reception of a reflected light pulse, and in addition, an electromagnetic wave sending-receiving apparatus 5 which sends and receives an electromagnetic wave 6 being longer in wavelength than the light is arranged in the coal preservatory, and sends the electromagnetic wave 6 and receives the reflected electromagnetic wave to measure a density inside the stored coal 3 on the above sending and receiving. The height of the whole range of the storing layer of the coal 3 is measured through a volume computer 4 by longitudinally and laterally scanning the light wave sending-receiving apparatus 1, and the volume of the stored coal 3 is computed on a scanning direction and the above height. The density of the whole range of the storing layer of the coal 3 is measured through a density distribution computer 7 by longitudinally and laterally scanning the electromagnetic wave sending-receiving apparatus 5, and the quantity of storing layer at a mass base is obtained through a mass computer 8 by multiplying the volume by the density of coal at each position.
