    摘要： The present invention relates to an electronic circuit that interrupts the application of electrical power to a motor after a predetermined period of time. The electronic circuit is disposed between a motor which drives a device from an initial position to a final position and a switch movable from a first position to a second position. A battery which supplies the electrical power for the motor is engaged with the switch. The control circuit includes at least two energy storage devices. Depending on the position of the switch, one of the energy storage devices will be fully charged by the battery source. Altering the position of the switch will cause the fully charged energy storage device to begin its discharge and the alternate energy storage device will be “instantly” charged. During the time that both energy storage devices have a significant charge on them, a control signal is generated. The control signal will be present until the discharging energy storage device falls below a threshold value. In response to the control signal, the electrical power source is applied to the motor and the motor will turn in the direction according to the polarity of the applied power source. In a second embodiment of the invention, electrical power to the motor may be interrupted prior to a full discharge of the energy storage device if the current drawn by the motor exceeds a predetermined threshold value for a minimal time period.

    摘要翻译： 电子电路技术领域本发明涉及一种电子电路，其在预定时间段之后中断对电动机的电力的施加。 电子电路设置在驱动器件从初始位置到最终位置的电动机和可从第一位置移动到第二位置的开关之间。 为电动机提供电力的电池与开关接合。 控制电路包括至少两个储能装置。 根据开关的位置，其中一个储能装置将被电池电源完全充电。 改变开关的位置将导致完全充电的能量存储装置开始放电，并且替代能量存储装置将被“即时”充电。 在两个能量存储装置对它们具有显着电荷的时间期间，产生控制信号。 控制信号将存在，直到放电能量存储装置下降到阈值以下。 响应于控制信号，将电源施加到电动机，并且电动机将根据所施加的电源的极性沿着该方向转动。 在本发明的第二实施例中，如果由电动机汲取的电流在最小时间段内超过预定的阈值，则可以在能量存储装置的完全放电之前中断对电动机的电力。

    摘要： A method and apparatus for aligning a laser beam coincident with a charged particle beam. The invention described provides a method for aligning the laser beam through the center of an objective lens and ultimately targeting the eucentric point of a multi-beam system. The apparatus takes advantage of components of the laser beam alignment system being positioned within and outside of the vacuum chamber of the charged particle system.

    摘要： A method for designing and using a partially manufactured semiconductor product is disclosed. The partially manufactured semiconductor product, referred to as a slice, contains a fabric of configurable transistors and at least an area of embedded memory. The method contemplates that a range of processors, processing elements, processing circuits exists which might be manufactured as a hardmacs or configured from the transistor fabric of the slice. The method then evaluates all the memory requirements of all the processors in the range to create a memory superset to be embedded into the slice. The memory superset can then be mapped and routed to a particular memory for one of the processors within the range; ports can be mapped and routed to access the selected portions of the memory superset. If any memory is not used, then it and/or its adjoining transistor fabric can become a landing zone for other functions or registers or memories.
