    • A steering assist apparatus includes a camera for picking up the rear side of a vehicle, a monitor disposed in a driver's compartment of the vehicle, a steering angle sensor for detecting a steering angle of a steering wheel, and a display controlling unit for displaying on the monitor an image through said camera when the vehicle reverses and for superimposing and displaying on said monitor a guide display for assisting the drive of the vehicle when the vehicle is to be parked. The guide display includes a steering start guide line fixedly displayed in a predetermined position of an image field of the monitor for guiding a steering start position for parking, and a steering amount guide mark moved and displayed along the steering start guide line on the image field of the monitor in correspondence with a steering angle of the steering wheel detected by the steering angle sensor. The driver performs the steering operation of the vehicle while recognizing the position for the opposite turning of the steering wheel and the steering amount and the steering start position for parking on the basis of the image on the rear side of the vehicle and the steering amount guide mark and the steering start guide line.
    • 转向辅助装置包括用于拾取车辆后侧的照相机,设置在车辆的驾驶室中的监视器,用于检测方向盘的转向角的转向角传感器,以及用于显示方向盘的显示控制单元 当车辆反转时,通过所述摄像机监视图像,并且在所述监视器上叠加和显示用于当车辆停放时辅助车辆的驱动的引导显示器。 引导显示器包括固定地显示在监视器的图像场的预定位置的导向引导线,用于引导用于停车的转向开始位置,以及沿着转向启动引导线在图像场上移动和显示的转向量引导标记 与转向角传感器检测到的方向盘的转向角对应的监视器。 驾驶员在基于车辆后方的图像识别出方向盘的相对转动的位置和转向量以及用于停车的转向开始位置的位置时,执行车辆的转向操作,并且转向量引导件 标记和转向启动指导线。

    • Biochemical optical resolution of DL-.alpha.-methylphenyl alanines in which DL-.alpha.-methylphenyl alanine amides are interacted with the culture products, or their treated products, of a microorganism capable of producing amidase is described. L-.alpha.-methylphenyl alanines having the general formula (I): ##STR1## wherein R.sub.1 and R.sub.2 may be independently a hydrogen atom or lower alkyl groups, or R.sub.1 and R.sub.2 may be alkylene groups combined together to form 5 through 8-membered rings is produced by the steps of:(a) making a DL-.alpha.-methylphenyl alanine amide having the general formula (II): ##STR2## wherein R.sub.1 and R.sub.2 are the same as defined above, interact with the culture product of a microorganism capable of producing enzyme catalyzing the hydrolysis of L-isomer of DL-.alpha.-methylphenyl alanine amides or the treated product thereof, whereby asymmetric hydrolysis of an L-.alpha.-methylphenyl alanine amide is effected; and(b) separating the resultant L-.alpha.-methylphenyl alanines from the hydrolysis mixture.
