Abstract: A footstep for an excavator is provided, in which the footstep, that is fixed to a track side frame so that an operator can get on/off a cab and so on therethrough, can be prevented from being damaged by rocks and so on during operation of the excavator in an inferior working environment. The footstep for an excavator, mounted on a track side frame of the excavator, includes an upper step composed of side plates formed on left and right sides to face each other, and a front plate formed in a body with the side plates and having through-holes formed on left and right sides thereof, to protect a head part of a fastening member, which fixes the footstep to the side frame, from an external impact; a fixing plate having both ends fixed to inner surfaces of the side plates to fix the upper step to the side frame by the fastening member that is fastened to pass through the through-holes; and a lower step fixed to lower ends of elastic pieces having upper ends fixed to the side plates, respectively.

Abstract: An apparatus for correcting a non-linear characteristic in a display device to keep the number of displayable colors as it is and to unify a picture quality for each product. In the apparatus, a bias voltage to be applied to a digital to analog converter converting a digital image signal into an analog image signal is changed in accordance with a logical value of the digital image signal. Accordingly, the apparatus generates an analog image signal in which the non-linear characteristic in the display device is compensated.
