Abstract: An abnormality behind a shielding object is discovered. There is provided a monitoring system including a video acquirer, a detector, and a notifier. The video acquirer of the monitoring system acquires a video. The detector of the monitoring system detects entering of a target object into a blind spot generated by a shielding object in the video and appearance of the target object from the blind spot. If the target object does not appear from the blind spot even after a first time elapses since entering of the target object into the blind spot, the notifier of the monitoring system makes a notification.

Abstract: Conveying operation equipment has a conveying carriage with an operating region between a workpiece support portion and a side of the conveying carriage. A reciprocating movement path of an operation device is provided such that part or the whole of the operation device is overlaid on the operating region on the conveying carriage and a synchronous forward-traveling mechanism which makes the operation device travel synchronously with the conveying carriage is formed with a transmission mechanism in an upper portion of the conveying carriage and a passive portion in a bottom portion of the operation device and a transmission state switch which switches the transmission mechanism to a transmission state at the beginning end position of the reciprocating movement path and which switches the transmission mechanism to a transmission release state at the terminal end position of the reciprocating movement path.

Abstract: Conveying equipment includes carriages having a frame with front and rear ends coupled to adjacent carriages by vertical support shafts and having a floor board which is supported by the frame. A floor board main portion has a protruding arc-shaped end edge concentric with one of the vertical support shafts and a floor board sub-portion which has a recessed arc-shaped end edge concentric with the other vertical support shaft. The protruding arc-shaped end edge in one carriage and the recessed arc-shaped end edge in an adjacent carriage are relatively rotatable around the common vertical support shaft located at the arc centers of each of the edges. The floor board main portion overhangs from one end of the frame in each of the carriages and is supported on an overhanging portion which overhangs from the floor board sub-portion in the adjacent carriage so as to be freely relatively rotated.

Abstract: A semiconductor device may include an element region and a peripheral voltage withstanding region. The peripheral voltage withstanding region includes inner circumferential guard rings; and outer circumferential guard rings having a width narrower than a width of the inner circumferential guard rings. An interval between the inner circumferential guard rings is narrower than an interval between the outer circumferential guard rings. Each of the inner circumferential guard rings includes a first high concentration region and a first low concentration region. Each of the outer circumferential guard rings includes a second high concentration region and a second low concentration region. A width of a part of each first low concentration region that is exposed on a front surface of the semiconductor device is wider than a width of a part of each second low concentration region that is exposed on the front surface.

Abstract: A conveying-traveling-body-utilizing conveying device links conveying traveling bodies to each other where load bars are continuous to each other. A linked part is provided at one end of the load bar, and a linking hook is provided at the other end which can engage with and disengage from the linked part. The linking hook is pivotally supported and is vertically movable between a pre-engagement orientation separated upward from the linked part, with respect to an engaged orientation of covering the linked part from above, and a standby orientation tilted to a lowering limit from the engaged orientation by an urging force. When the linking hook is in the standby orientation, longitudinally adjacent conveying traveling bodies can approach each other to a connected state, where the respective load bars are abutted against each other, without the linking hook in the standby orientation and the linked part contacting each other.
