摘要： An object of the present invention is to provide a punching method using a punch, which makes it possible to effectively improve the durability of a tooth portion of the punch. In a punching method using a punch for forming a through-hole in a workpiece by punching the workpiece using a punch, at least a tooth portion of the punch is made substantially solid when the workpiece is punched by the punch, and the tooth portion is made substantially hollow, thereby a diameter of the tooth portion is reduced by a reaction force received from the workpiece, when the workpiece is separated from the punch after the punching of the workpiece.

摘要： An internal combustion engine includes: a variable valve train mechanism, configured to receive a cam displacement of an inlet cam so as to vary a driving output for driving an inlet valve continuously from a maximum valve lift to a minimum valve lift so as to match the driving output with a running condition of the internal combustion engine; and a control part, configured to control the variable valve train mechanism so as to set a valve lift of the inlet valve to a starter valve lift when starting the internal combustion engine in a cold state. The starter valve lift is formed so that a valve opening period of the inlet valve is set to encompass an overall area of an induction stroke period of the internal combustion engine from a top dead center to a bottom dead center of the induction stroke period.
