    • A level shifter includes a latch supplied at a first voltage VDD1. First and second switches are connected in series with first and second latches and are cross-coupled to maintain the state of the latches during a stability period. A controller responds to a change of state of an input signal at a voltage different from the first voltage at an end of the stability period to deactivate both the first and second switches, to cause third and fourth switches to deactivate both the first and second latches during a transition period, and subsequently to change the state of the latch and maintain the changed state during the subsequent stability period. This avoids undesirable compromise between current consumption and transfer delay, as in a conventional level shifter.
    • 电平移位器包括以第一电压VDD1提供的锁存器。 第一和第二开关与第一和第二锁存器串联连接并且交叉耦合以在稳定期间保持锁存器的状态。 控制器在稳定时段结束时以不同于第一电压的电压对输入信号的状态改变进行响应,以使第一和第二开关两者同时失效,以使第三和第四开关停止第一和第二锁存器 并且随后改变锁存器的状态并在随后的稳定期间保持改变的状态。 这避免了电流消耗和传输延迟之间的不利影响,如在常规电平转换器中。

    • The present invention relates to a conversational automatic programming device or the like capable of generating an NC program in a simpler manner and in a shorter period of time. The automatic programming device is provided with, a machining-profile setting processor in which based on data for specifying a geometric entity selected as a contour shape of a machined portion, out of geometric entities of a geometry defined by two-dimensional CAD data, the geometric entity corresponding to the data is recognized, and based on the recognized geometric entity, a machining profile which is the contour shape of the machined portion is set; a CL-data generating processor for generating tool path data based on the set machining profile; and an NC-program generating processor for generating an NC program based on the generated tool path data. The machining-profile setting processor corrects the recognized geometric entity and/or adds a new geometric entity such that a continuous line without bifurcation all the way from a starting point to an ending point is formable, and thereafter, sets the machining profile.
