Abstract: A control system of a loading machine, having working equipment including a bucket, includes a control device. The control device detects a first surface of an excavated object excavated by the bucket during excavation work, calculates an under-excavation load angle indicating an angle of the first surface with respect to the horizontal plane on the basis of detection data of the first surface, and estimates the weight of the excavated object on the basis of the under-excavation load angle.

Abstract: A work machine control device includes a measurement-data acquisition unit that acquires measurement data of a measurement device that measures a work target, the measurement device being mounted on a work machine including a working equipment, an algorithm selection unit that selects a specific algorithm that processes the measurement data depending on work of the work machine, and a calculation unit that processes the measurement data based on the algorithm selected by the algorithm selection unit to calculate a parameter regarding the work target.

Abstract: In a printing method of a lithographic printing plate precursor as defined herein, the following steps (i) to (v) are performed at start of printing in order of (i), (ii), (iii), (iv) and (v) or in order of (i), (iii), (ii), (iv) and (v): (i) exposing imagewise the lithographic printing plate precursor and then mounting on a plate cylinder of a printing machine; (ii) supplying by spraying at least any of dampening water and an aqueous solution containing an organic solvent as defined herein; (iii) rotating water feed rollers; (iv) bringing the dampening roller into contact with the lithographic printing plate precursor to supply dampening water from the dampening roller to the precursor; (v) bringing an inking roller into contact with the lithographic printing plate precursor to supply printing ink from the inking roller to the precursor, and supplying printing paper as defined herein.
