摘要： A safety switch is provided in which the open-close condition of a switching contact provided in a lock mechanism is reliably switched in a manner coupled with a motion of a lock member between a lock position and a unlock position. Since a link member, which directly and simultaneously switches the open-close conditions of normally-open and normally-closed switching contacts pursuant to the motion of a lock member, is provided, the open-close conditions of the normally-open and normally-close switching contacts can be switched reliably in a coupled manner with the motion of the lock member between the lock position and the unlock position. As a result, for example, by monitoring the open-close conditions of the normally-open and normally-close switching contacts, it is possible to determine to which of the lock position and the unlock position the lock member has moved, that is, which of the locked state and the unlocked state the rotation of the drive cam is in.

摘要： A safety switch is provided which is increased in durability and which offers a high degree of freedom of mounting the safety switch to place.A switch body has a rectangular solid shape. An actuator entrance hole is formed at one of the opposite corner portions of the switch body whereas a cable lead-out port is formed at the other corner portion, whereby the safety switch is increased in the degree of mounting freedom. Thus is offered a wider choice of place to mount the safety switch. The switch body is formed with only one actuator entrance hole so that the safety switch is prevented from suffering failure caused by foreign substances invading through an actuator entrance hole left unused. In addition, a driving cam may be formed with an engaging portion and a cam curve portion in spaced relation so that the driving cam is configured to be free from an area having poor strength. Thus, the driving cam is increased in strength. This leads to the increased durability of the safety switch.

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 safety 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 digital signal processing apparatus for matching the sampling frequency of an input digital signal to an internal sampling frequency. The digital signal processing apparatus has a sampling frequency converting unit for matching the sampling frequency of an input digital signal to an internal sampling frequency, a sampling frequency detection unit for detecting the sampling frequency of the input digital signa, a frequency difference calculating unit for finding the frequency difference between the inherent sampling frequency of the input digital signal and the sampling frequency detected by the sampling frequency detection unit and a pitch shifting unit for shifting the pitch of an output digital signal of the sampling frequency converting unit based upon said frequency difference. If the input digital signal has the sampling frequency slightly offset from the inherent sampling frequency, the signal of the inherent sampling frequency can be recovered, while the pitch can be restored to the inherent pitch.
