摘要： A safety switch is described in which a switching contact in a lock mechanism switches between an open and closed condition. Switching is coupled to a lock member moveable between a locked position, locking a drive cam, and an unlocked position, allowing the cam to rotate. A link member, cooperating with the lock member, switches between open and closed conditions of normally-open and normally-closed switching contacts, indicating movement of the lock member between the locked position and the unlocked position. By monitoring the open and closed conditions of the normally-open and normally-closed switching contacts, it is possible to determine the state of the lock member, i.e., whether it is in the locked position or in the unlocked position. It therefore can be determined whether the drive cam is in the locked or unlocked (i.e., free to rotate) state.

摘要： A safety switch capable of detecting withdrawal of an actuator from a switch main unit in a sure and reliable manner even when the safely switch, including a lock mechanism, is in a locked condition and an attempt is made to forcibly withdraw the actuator from the switch main unit. Even when a drive cam becomes capable of rotation since not less than one of a notch cut-out section and a lock member is broken by forcibly extracting an actuator with rotation of the drive cam locked, a cam curve section of the drive cam and an operating rod are in a normal condition and free of breakage. Accordingly, if the drive cam rotates in a counter-clockwise direction, normally-closed contacts of a contact section adopt an open condition normally, and even in situations where the actuator is withdrawn from the switch main unit with a force equal to or greater than the fracture strength of the safety switch, withdrawal of the actuator from the switch main unit can be detected in a sure and reliable manner.

摘要： A signal output is taken out from the input stage or respective output stages of the signal characteristic processing means through a signal line selected by selecting means. In accordance with the taken signal, the level control signal generating means sets the output level of the audio output signal. Then, the output level setting means sets the output level of the audio output signal in accordance with the level control signal outputted by the level control signal generating means. Therefore, the switching noise due to switch signal lines by selecting means is prevented from entering into an audio output signal during the processing of the output level of the audio input signal.

摘要： In addition to an output Y(n) of an adding device, a dither output of a dither generating circuit is supplied to an adding device. The output Y(n) of the adding device is added to a bit that is one bit lower than the LSB of the shortest word length of the hardware (namely, the place of LSB/2). The output of the adding device is supplied to a delay device. In other words, when the shorter word length is 32 bits corresponding to the word length of the RAM of the delay device, the dither is added to the bit 33. In the data Y(n) to which the dither has been added, the low order bits thereof are truncated corresponding to the word length of the delay device. The resultant data is supplied as next timing output data Y'(n-1) to the delay device and stored therein.

摘要： In this digital signal measurement apparatus, an approach is employed to deliver a measurement signal from a measurement signal generator to a measured circuit to transform the signal on the time base through the measured circuit to a signal on the frequency base by a frequency base transform circuit and to further obtain a signal on the time base by a time base transform circuit. Thus, a difference between the signal on the time base through the measured circuit and the signal on the time base from the time base transform circuit is employed. Thus, for example, even if the measured circuit is a linear system, a measured result in the digital region and a result of the analog measurement can be in correspondence with each other. Accordingly, gain correction of a measurement signal is unnecessary, thus making it possible to prevent an increase in an error of a measured result of S/N.
摘要翻译：在该数字信号测量装置中，采用将测量信号从测量信号发生器传送到测量电路的方法，以便通过测量电路将基于时基的信号通过频率基变换电路并且通过时基变换电路进一步获得时基上的信号。因此，采用通过测量电路的时基上的信号与来自时基变换电路的时基上的信号之间的差。因此，例如，即使测量的电路是线性系统，数字区域中的测量结果和模拟测量的结果可以彼此对应。因此，测量信号的增益校正是不必要的，因此可以防止S / N的测量结果的误差的增加。
