Abstract: A glass substrate includes a first major surface, a second major surface, an end surface, a first boundary surface, a second boundary surface, and a bent portion in which the first major surface is bent so as to be concave and the second major surface is bent so as to be convex. The bent portion includes a portion in which a distance D1 from the end surface to the first major surface in a tangential direction, extending from the end surface toward the first major surface, of the glass substrate is longer than a distance D2 from the end surface to the second major surface in a tangential direction, extending from the end surface toward the second major surface, of the glass substrate. A difference between the distance D1 and the distance D2 is 50 ?m or larger.

Abstract: A first payload computation value which represents a weight of loads loaded on the work implement in a first attitude is obtained. The first attitude and a second attitude are equal to each other in ratio between a horizontal distance from a position of a center of gravity of a first link member to a base end of the first link member and a horizontal distance from a position of the center of gravity of the loads loaded on the work implement to the base end. A second payload computation value which represents a weight of loads loaded on the work implement in the second attitude is obtained. When the first payload computation value and the second payload computation value are determined as being different from each other, a weight of a second link member is changed and processing above is repeated.

Abstract: A work machine includes a vehicular body, a work implement supported on the vehicular body, and an engine which is a drive source of the work implement. The control device of the work machine includes a rotation speed setting member manually operable for setting a target rotation speed of the engine and a controller that selectively carries out any one of ordinary control and intervention control. When ordinary control is carried out, an engine controller controls the engine at the target rotation speed based on an operation onto the rotation speed setting member. When intervention control is carried out, an intervention controller estimates contents of works by the work implement. The engine controller sets the target rotation speed corresponding to the estimated contents of works and controls the engine at the set target rotation speed regardless of an amount of operation onto the rotation speed setting member.

Abstract: A payload calculation value (CalcuPayload) of a load within a bucket is calculated based on load of a boom cylinder. An amount of change per unit time in information on at least one of an operation command value for operating the boom cylinder and a speed of extension and contraction of the boom cylinder is sensed. A payload value is determined by correcting based on the amount of change per unit time, the payload calculation value (CalcuPayload) obtained by calculation.
