The present invention provides a cutting element having a cylindrical body having a canted end face on which is formed an ultra hard material layer and to a bit incorporating such cutting element. The electrical surge protection device includes a support that is structured to be installed on the electrical enclosure and a number of varistors or other electrical components that will, in the event of a voltage surge on a line conductor, shunt electrical energy from the voltage surge to the ground or neutral conductor with which it is connected. The flexural elements allow the proof mass to move in the sensitive direction in the plane of suspension while restricting movement in all off-axis directions. A tool is provided for lifting the valve element from the manifold that includes a pivotal removal bar that can be attached to a top of the valve element. The electron gun irradiates the electron beam to the semiconductor integrated circuit device.
