摘要： PROBLEM TO BE SOLVED: To provide a method for determining a computer-based collection start time for acquiring operation performance data of a monitoring object program at the same timing in a plurality of computers differed in operating state.
SOLUTION: For each computer, using a time difference between operation performance data collection scheduled time and actual collection time of an item that is a monitoring object, the collection start time in the next collection is moved forward by the time difference. Calculation of the time difference between collection scheduled time and actual collection time or reflection to the collection start time are periodically performed according to a predetermined review interval.

摘要： PROBLEM TO BE SOLVED: To make it possible to very precisely verify the appropriateness of a work which is performed to an information processing device.
SOLUTION: An information processing system stores a permission file list 500 and an exceptional operation list 600, determines, based on an operation history 800, whether the present operation is a normal operation which accords with a scheduled operation or a recovery operation, and stores the result of the determination as the determination reference 414. If operation contents 815 in the operation history 800 exist in a work plan 300, the information processing system determines that the operation state is normal. If the operation contents 815 do not exist in the work plan 300 and the operation contents 815 indicate an operation to a file which exists in the permission file list 500, the information processing system determines that the work state is normal. If the operation contents 815 do not exist in the work plan 300 and the operation contents 815 don't indicate an operation to a file which exists in the permission file list 500, the information processing system determines, according to the determination reference 414, whether the work state is normal or abnormal by using the exceptional operation list 600.

摘要： PROBLEM TO BE SOLVED: To suppress a calculation load to the minimum, to surely obtain the maximum adhesion torque, to improve acceleration/deceleration performance when a slip slide is detected, and to surely suppress the slip slide even if an adhesion state between wheels and rails is rapidly changed, and an adhesion coefficient is instantaneously reduced.SOLUTION: An estimated adhesion torque is always stored so as to suppress a calculation load to the minimum and surely obtain a maximum adhesion torque. When a slip slide is detected, a maximum is obtained from a plurality of the stored estimated adhesion torques just before the slip slide is detected. The maximum is considered as the maximum adhesion torque. A value of the maximum adhesion torque just before the slip slide is detected and a value of the estimated adhesion torque when the slip slide is detected are calculated and compared. If a calculation value exceeds a threshold, a condition that an adhesion coefficient is rapidly reduced is determined. In comparison with a condition that the adhesion coefficient is not rapidly reduced, a suppression/return rate of the torque is switched to a low value. The slip slide is surely suppressed by reducing a torque value to a smaller value during suppression/return.
摘要翻译：要解决的问题：为了将计算负荷降至最低，确保获得最大的附着力矩，以便在检测到滑动滑块时提高加速/减速性能，并且即使在车轮与车轮之间的粘附状态导轨快速变化，粘附系数瞬时减小。解决方案：总是存储估计的粘合扭矩，以将计算负荷抑制到最小，并确保获得最大的附着扭矩。当检测到滑动滑块时，从检测到滑动滑块之前的多个所存储的估计粘附扭矩获得最大值。最大值被认为是最大附着力矩。检测刚好在滑动滑块之前的最大粘附扭矩的值，并且计算并比较当滑动滑块被检测时估计的粘附扭矩的值。如果计算值超过阈值，则确定粘附系数迅速降低的条件。与粘附系数不迅速降低的条件相比，扭矩的抑制/返回率被切换为低值。在抑制/返回期间，通过将转矩值减小到较小值，可以确保滑块滑动。

摘要： A control system including a central processing unit or calculation device and a plurality of input/output devices for inputting and outputting data, which includes a request or a response in accordance with a command to or from a control target. The calculation device controls the input/output devices; and plurality of relay devices for relaying communication between the calculation device and the input/output devices. The relay devices are connected to the input/output devices via a ring-shaped communication line or network, has a communication judgement section for judging whether to relay data or not, and relays the communication of the data on the basis of the judgment result of the communication judgment section. The system can be configured to have duplicated ring-shaped communication lines along with duplicated calculation and input/output units improving the reliability and availability of the communication quality of the system. Where there are duplicated systems, the judgement sections can be used to also monitor whether the data is being transmitted whilst the other is working, and also check the direction of the data transmission between devices.

摘要： An ejector can obtain a sufficiently large suction air quantity without reducing the ultimate vacuum. A diffuser is disposed downstream of a nozzle to form a single Laval nozzle. A suction port is provided between the nozzle and the diffuser. The inlet of the diffuser is enlarged in width so that the side walls thereof extend approximately parallel to each other along the axis of the diffuser over a predetermined length. When air is caused to flow from an inlet closer to the nozzle toward an outlet by the engine intake negative pressure, the flow velocity at a throat portion reaches the sound velocity owing to the effect of the Laval nozzle. Consequently, a high negative pressure is generated at the suction port. The parallel portion formed by enlarging the inlet of the diffuser allows the suction air quantity to be increased without reducing the effect of the Laval nozzle.
