    • The invention relates to a lifting appliance or a jack for vehicles preferably comprising axles or four drive wheels. Said lifting appliance mainly comprises a base to which an arm is connected in an articulated manner, said arm containing a height-adjustable rod having an upper end which is positioned beneath a vehicle body or an axle, in order to change a wheel, for example. The invention enables the above-mentioned disadvantages to be mitigated, in that the inventive appliance eliminates certain steps carried out to lift the vehicle or to fold up the arm of the jack once the wheel has been changed, especially the use of a crank for cranking up the jack. Said novel appliance requires only one manual operation, that is mainly to manually position the appliance beneath the vehicle, in the usual spot for said function.
    • 本发明涉及用于车辆的起重设备或千斤顶,优选地包括轴或四个驱动轮。 所述提升装置主要包括一个以铰接方式连接臂的基座,所述臂包含高度可调的杆,其具有位于车身或车轴下方的上端,以便改变车轮,例如 。 本发明使得能够减轻上述缺点,因为本发明的设备消除了一旦车轮已经改变就执行提升车辆或折叠千斤顶的某些步骤,特别是使用用于起动的曲柄 千斤顶 所述新型设备仅需要一个手动操作,主要是在所述功能的通常位置下手动地将设备定位在车辆下方。

    • A heterojunction bipolar transistor with self-aligned features having a self-aligned dielectric sidewall spacer disposed between base contact and emitter contact, and self-aligned base mesa aligned relative to self-aligned base contact. The base contact is self-aligned relative to the self-aligned dielectric sidewall spacer providing a predetermined base-to-emitter spacing thereby. The emitter may be an n-type, InP material; the base can be a p-type InGaAs material, possibly carbon-doped. The fabrication method includes forming a emitter electrode on an emitter layer; using the emitter contact as a mask, anisotropically etching the emitter exposing the base layer; forming a self-aligned dielectric sidewall spacer upon the emitter and base; self-alignedly depositing a self-aligned base electrode; using the self-aligned base electrode as a mask, anisotropically etching the base layer to expose the subcollector; and depositing a collector electrode on the subcollector layer.
    • 具有自对准特征的异质结双极晶体管,其具有设置在基极接触和发射极接触之间的自对准电介质侧壁间隔,以及相对于自对准基极接触对准的自对准基台面。 基底接触件相对于自对准电介质侧壁间隔自对准,从而提供预定的基极间距离。 发射极可以是n型InP材料; 该基底可以是p型InGaAs材料,可能是碳掺杂的。 制造方法包括在发射极层上形成发射电极; 使用发射极接触作为掩模,各向异性地蚀刻暴露基底层的发射体; 在发射极和基极上形成自对准的电介质侧壁间隔物; 自对准地沉积自对准的基极; 使用自对准基极作为掩模,各向异性地蚀刻基底层以暴露子集电极; 以及在所述子集电极层上沉积集电极。

    • An optical mass storage device for use in data processing systems. Two or more lasers provide separate read and write laser beams having different wavelengths. The read and write laser beams can be orthogonally polarized. A polarizing beam splitter combines the read and write beams along a common optical path to an optical head. The head directs the combined beam to a magneto-optic storage medium. A read beam is reflected back by the medium to the common path through the head. A dichroic beam splitter disposed in the common path between the head and the polarizing splitter reflects the read beam to an optical detector. If more than one write laser is necessary, a second dichroic splitter can be used to combine the multiple write beams and the read beam.
    • 一种用于数据处理系统的光学大容量存储装置。 两个或更多个激光器提供具有不同波长的单独的读和写激光束。 读写激光束可以是正交极化的。 偏振分束器将沿着公共光路的读取和写入光束组合到光学头。 头部将组合的光束引导到磁光存储介质。 读取光束被介质反射回通过头部的公共路径。 设置在头部和偏振分离器之间的公共路径中的二向色分束器将读取的光束反射到光学检测器。 如果需要多于一个写入激光器,则可以使用第二分色器来组合多个写入光束和读取光束。
