  • Publication number: 20210397211
    Abstract: A delay time detection circuit includes below configurations. A clock generation unit generates a sub scale clock signal, based on a system clock signal. A count unit generates a count signal while sequentially and repeatedly incrementing a count number, based on the sub scale clock signal. A sub scale signal generation unit receives the count signal, and generates sub scale signals, equal in number to the count number, that each have, at a rate of once in the count number, a rectangular wave for a duration being associated with a second period and that are shifted in timing relative to one another according to the second period. A delay time calculation unit receives the input clock signal, and calculates a delay time within a range of the first period of the input clock signal with respect to the system clock signal, based on one of the sub scale signals.

  • Publication number: 20210237141
    Abstract: Provided is an adjustment device of a punching device which punches a workpiece placed on a die having a punching die with a punch so that the workpiece is punched into a predetermined shape. The adjustment device of the punching device includes a first drive mechanism that moves the punch or the die in a direction orthogonal to a punching direction, and a controller connected to the first drive mechanism in a communicable manner. The controller brings the punch and the die into contact with each other by moving the punch or the die in four orthogonal directions in a plane perpendicular to the punching direction from an initial position where the punch is inserted into the punching die. Based on a distance between the initial position and each contact position in the four directions, the controller causes the first drive mechanism to move the punch or the die to a center position where a central axis of the punch and a central axis of the die are aligned with other.
