    • A detachable chair or gondola lift is disclosed wherein an alternator is driven by a rope bull-wheel. The alternator supplies a synchronous motor for driving friction wheels or other mechanisms for driving the cars in an end station of the chair or gondola lift. The electrical connection between the alternator and the synchronous motor ensures synchronous rotation of the motor. The alternator can be connected to the bull-wheel by a multiplier gear, the bull-wheel being either a tension bull-wheel or a driving bull-wheel. In the case of a tension bull-wheel, the alternator is mounted on the bull-wheel support carriage to avoid a flexible mechanical transmission. The alternator can be coupled to the high speed shaft of a driving bull-wheel reducer gear, for example, by a trapizoidal belt transmission. At low speed, the excitation of the alternator is increased to preserve the synchronism of the movements. Such excitation is accomplished by an auxiliary power source, or by self excitation by suitable permanent magnets and filters.
    • 公开了一种可拆卸的椅子或吊车升降机,其中交流发电机由绳索斗轮驱动。 交流发电机提供用于驱动摩擦轮的同步电动机或用于在椅子或吊车升降机的终端中驾驶汽车的其它机构。 交流发电机和同步电机之间的电气连接确保电机同步旋转。 交流发电机可以通过一个倍增器连接到斗轮,这个斗轮是紧张的斗轮或是一个驱动的斗轮。 在张力斗轮的情况下,交流发电机安装在斗轮支撑架上,以避免弹性机械传动。 交流发电机可以例如通过带状带传动装置联接到驱动轮轮减速器齿轮的高速轴上。 在低速时,增加交流发电机的激励以保持运动的同步。 这种激励是通过辅助电源实现的,或者通过合适的永久磁铁和滤波器的自激而实现。

    • A MOSFET semiconductor device includes a substrate, a gate electrode, a gate oxide, first and second sets sidewall spacers, and nickel silicide layers. The gate oxide is disposed between the gate electrode and the substrate, and the substrate includes source/drain regions. The gate electrode has first and second opposing sidewalls, and the first set of sidewall spacers are formed from a silicon starved spacer materials, examples of which include SiOX, wherein X>2, SiNX, wherein X>1, or SiOXNY, wherein X+Y>2. The second set of sidewall spacers are formed from silicon nitride and are respectively disposed adjacent the first set of sidewall spacers. The nickel silicide layers are disposed on the source/drain regions and the gate electrode. The first set of sidewall spacers act as a silicon diffusion barrier for preventing silicon from migrating from the gate electrode to the second set of sidewall spacers. A method of manufacturing the semiconductor device is also disclosed.

    • A method of manufacturing a MOSFET semiconductor device comprises providing a gate electrode having first and second opposing sidewalls over a substrate having source/drain regions; providing a gate oxide between the gate electrode and the substrate; forming first and second sidewall spacers respectively disposed adjacent the first and second sidewalls; forming nickel silicide layers disposed on the source/drain regions and the gate electrode, and two etching steps. The nickel silicide layers are formed during a rapid thermal anneal at temperatures from about 380 to 600° C. The first etch is performed with a sulfuric peroxide mix to remove unreacted nickel, and the second etch is performed with an ammonia peroxide mix to remove nickel silicide formed over the first and second sidewall spacers.
