    • A method for manufacturing an expanded mesh sheet, includes the steps of: forming a plurality of slits on a strip at predetermined pitches to simultaneously form a plurality of strip-shaped lift portions and connecting portions for connecting the strip-shaped lift portions to each other in a lattice pattern, the slits each being intermittently formed in a longitudinal direction of the strip and the adjacent slits in a widthwise direction of the strip being shifted to each other in the longitudinal direction of the strip; and expanding the strip in the widthwise direction thereof. An apparatus for manufacturing the sheet, includes: a pair of rolls engaged to each other, each roll having a plurality of disk-shaped cutters; and a driving device for driving the rolls for rotation. Each cutter has a cutting edge portion and a relief on a periphery thereof at predetermined pitches to form slits, each of which extends in a longitudinal direction of the strip, on the strip by the cutting edge portions of the cutters of the rolls to form strip-shaped lift portions and to form a connecting portion for connecting the strip-shaped lift portions to each other on a position between the slits on an extending direction of the slits by the reliefs of the cutters of the rolls.
    • 一种膨胀网片的制造方法,其特征在于,包括以规定的间距在条形状上形成多个狭缝,同时形成多个带状的提升部,以及将带状升降部彼此连接的连接部 在格子图案中,沿条带的纵向方向间断地形成的狭缝和条带的宽度方向上的相邻狭缝在条带的纵向方向上彼此偏移; 并且在其宽度方向上使带材膨胀。 一种用于制造片材的装置,包括:一对彼此接合的辊,每个辊具有多个盘形切割器; 以及用于驱动辊旋转的驱动装置。 每个切割器以预定的间距具有切割边缘部分和其周边上的凸起,以形成狭缝,每个狭缝在条带的纵向方向上通过辊的切割器的切割边缘部分在条带上延伸以形成条带 并且形成连接部分,用于通过辊的切割器的凹槽在狭缝的延伸方向上在狭缝之间的位置处将条形提升部分彼此连接。

    • An electrically driven vehicle equipped with electric motors (1, 4) for driving or braking drive wheels (3, 6), and an electric motor controller (33) for controlling the electric motors includes: wheel speed detectors (9 to 12) for detecting the wheel speed of the drive wheels and that of idler wheels (7, 8); computing means (22 to 28, 35 to 38) for computing the slip ratio of the drive wheels based on the wheel speed of the drive wheels and that of the idler wheels; and a determiner (29) for determining that the drive wheels are slipping if the slip ratio exceeds a slip ratio determination value. If the wheel speed of the idler wheels is lower than set speeds Va2, Vb2, then the determiner (29) changes the slip ratio determination value to a value having as the same sign as, and a larger absolute value than, the values λa2, λb2 used when the wheel speed of the idler wheels is higher than the set speeds Va2, Vb2. This structure shortens acceleration time during acceleration traveling and reduces braking distance during deceleration traveling while inhibiting vibrations of the electrically driven vehicle.
    • 一种配备有用于驱动或制动驱动轮(3,6)的电动机(1,4)的电动车辆和用于控制电动机的电动机控制器(33),包括:用于检测的车轮速度检测器(9至12) 驱动轮的轮速和惰轮(7,8)的转速; 用于基于所述驱动轮的轮速和所述惰轮的车轮速度计算所述驱动轮的打滑比的计算装置(22至28,35至38); 以及如果滑移比超过滑移率确定值,则确定驱动轮滑动的确定器(29)。 如果惰轮的车轮速度低于设定速度Va2,Vb2,则确定器(29)将滑移率判定值改变为具有与值λa2,Vb2相同的符号和更大的绝对值的值, 当惰轮的车轮速度高于设定速度Va2,Vb2时,使用lambdab2。 该结构缩短了加速行驶时的加速时间,并且减少了减速行驶时的制动距离,同时抑制了电动车辆的振动。
