    • When the control unit feedback-controls the DC brushless motor of the roller pump 5 to be driven for transferring the liquid in the flexible tube by using the pulse number of the encoder pulse from the encoder unit, the pulse number of the 4-multiplied encoder pulse, which is obtained by multiplying the pulse number of the encoder pulse by 4 by means of the frequency 4-multiplying circuit, is counted by means of the pulse counter. Therefore, since the encoder unit can multiply the pulse number of the encoder pulse which corresponds to the rotation of the output shaft of the DC brushless motor, the liquid in the flexible tube can be transferred with high constantivity even if the light-passing portion and the light-interrupting portion of the first and second encoding patterns can not been increased due to structural limitation. That is, since the resolution of the liquid flow rate to be detected with the encoder pulse to be output by the encoder unit is enhanced, the number of rotation of the output shaft of the DC brushless motor can be detected with sufficiently high resolution even if the rotation speed of the output shaft of the DC brushless motor are lowered
    • 当控制单元通过使用来自编码器单元的编码器脉冲的脉冲数来反馈控制要驱动的用于传送柔性管中的液体的辊式泵5的DC无刷电动机时,4倍编码器的脉冲数 通过脉冲计数器对通过乘法器4乘法电路将编码器脉冲的脉冲数乘以4获得的脉冲进行计数。 因此,由于编码器单元可以将对应于直流无刷电动机的输出轴的旋转的编码器脉冲的脉冲数乘以,即使光通过部分和 由于结构限制,第一编码图案和第二编码图案的光中断部分不能增加。 也就是说,由于要用由编码器单元输出的编码器脉冲检测的液体流速的分辨率增强,所以可以以足够高的分辨率检测DC无刷电动机的输出轴的旋转次数,即使 直流无刷电动机的输出轴的转速降低

    • An automatic brake control system brakes a driving vehicle according to a target brake control amount calculated by a neural network. The system detects vehicle speed of the driving vehicle, and detects the actual distance between the driving vehicle and a vehicle ahead of the driving vehicle. The system calculates a reference distance defined as a physically preferred distance between the driving vehicle and the vehicle ahead of the driving vehicle according to the vehicle speed, and normalizes the actual distance with the reference distance in order to obtain a normalized distance in a dimensionless quantity. The neural network calculates target brake control amount according to the vehicle speed and the normalized distance, and the automatic brake control system brakes the driving vehicle according to the target brake control amount.

    • A warning system estimates the possibility of the off-course travel of a vehicle while traveling through a curve before the vehicle enters the curve and gives the driver a warning properly. The warning system comprises an image recognizing means for obtaining three-dimensional image data on the road extending ahead of the vehicle and the traffic environment lying ahead of the same by recognizing conditions of the road and the traffic, a curve detecting means for detecting a curve on the basis of the image data before the vehicle enters the curve, a turning speed calculating means for calculating a reference turning speed at which average drivers will drive the vehicle traveling the curve on the basis of the radius of curvature of the curve and the width of the lane represented by the image data, a relative curve sharpness detecting means for deciding whether or not the relative sharpness of the curve is critical by comparing the reference turning speed with the actual traveling speed of the vehicle, and an off-course travel estimating means for deciding, when the relative sharpness detecting means decides that the relative sharpness of the curve is critical, whether or not the driver has carried out danger avoiding operations from signals indicating decelerating operations, and, if any danger avoiding operation is not executed, deciding that off-course travel is possible and giving a warning.
