    • Automobile theft is running rampant throughout the country, and many automobile stealing organizations are well organized, and have the necessary techniques to enable them to select and steal virtually any automobile. In a matter of a few hours they can change numbers, and other identifying data and give the automobile a new identity and appearance so that the automobile can be quickly sold at somewhat reduced prices. The overall profits are indeed very substantial. We have devised a theft proof locking system, including a key operated unit, which can be positioned at any desired location in the vehicle, and is operable to fully apply the brakes to all four wheels of the vehicle. This renders the vehicle immobile, even though the engine can be started and run. The only way that this locking system can be rendered inoperable is by the act of unlocking it with the key. It is therefore impossible to move the vehicle without lifting it bodily to load it onto a trailer or transport.
    • 汽车盗窃在全国各地猖獗,许多汽车盗窃组织组织良好,并拥有必要的技术,使他们能够选择和窃取几乎任何汽车。 在几个小时之内,他们可以改变数字和其他识别数据,并给汽车一个新的身份和外观,使汽车能够以较低的价格快速出售。 整体利润真的很大。 我们设计了一种防盗锁定系统,包括一个可以定位在车辆任何所需位置的钥匙操作单元,并可操作以将制动器完全施加到车辆的所有四个车轮上。 这使得车辆不动,即使发动机可以启动和运行。 这种锁定系统可以被无法操作的唯一方法是通过用钥匙解锁锁定系统的动作。 因此,不可能将车辆抬起而不必将其装载到拖车或运输工具上。

    • This invention relates to a field effect transistor level converter for converting bipolar transistor logic levels to field effect transistor logic levels. First and second field effect transistors have their source and gate electrodes connected in common. The bipolar input signal is received at the common source connection while the gate electrodes receive a fixed reference potential that is equal to the threshold voltage VT plus the lowest possible high binary level of the bipolar input logic. The drain electrode of the first field effect transistor is connected to the output terminal of the level converter and the source electrode of a source follower transistor. The drain electrode of the second transistor is connected to a load device and to the gate of the source follower transistor which has its drain electrode connected to VH. This arrangement produces at the first output terminal a potential swing of approximately 0 to 7 volts in response to an input signal in the range of 0.8 to 2.0 volts.
    • 本发明涉及用于将双极晶体管逻辑电平转换为场效应晶体管逻辑电平的场效应晶体管电平转换器。 第一和第二场效应晶体管的源极和栅极共同连接。 双极性输入信号在公共源极连接处被接收,而栅电极接收等于阈值电压VT加上双极性输入逻辑的最低可能的高二进制电平的固定参考电位。 第一场效应晶体管的漏电极连接到电平转换器的输出端和源极跟随器晶体管的源电极。 第二晶体管的漏电极连接到负载器件和源极跟随器晶体管的栅极,其漏极连接到VH。 这种布置在第一输出端产生响应于0.8至2.0伏范围内的输入信号的大约0至7伏特的电位摆动。
