A wiring board for mounting a semiconductor element or electronic component having a plurality of wiring layers, an insulating layer provided between these wiring layers, and a via which is provided to the insulating layer and which electrically connects the wiring layers. In this wiring board, the cross-sectional shape of the via in the plane parallel to the wiring layers is obtained by the partial overlapping of a plurality of similar shapes (circles). Stable operation can be obtained in a semiconductor element by minimizing obstacles to increased density, effectively increasing the cross-sectional area of the via, and preventing the wiring resistance from increasing by making the cross-sectional shape of the via into a shape obtained by the partial overlapping of a plurality of similar shapes.

Floor panels are shown, which are provided with a mechanical locking system including tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti-backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.
