摘要： A hydraulic drive apparatus includes a boom flow rate control valve, a target boom cylinder speed calculation part, a pressing force calculation part, a correction part, and a boom flow rate operation part. The target boom cylinder speed calculation part calculates a target boom cylinder speed for making the construction surface by the bucket closer to the target construction surface. The pressing force calculation part calculates the pressing force by which the bucket is pressed against the construction surface, based on the cylinder thrust of the boom cylinder and the center-of-gravity position information on the center-of-gravity position of the work device. The correction part corrects the target boom cylinder speed to make the deviation between the target pressing force and the calculated pressing force closer to 0. The boom flow rate operation part operates the boom flow rate control valve to provide the corrected target boom cylinder speed.

摘要： A welding power source is configured to supply a welding current to a wire as a consumable electrode. The welding power source includes a controller configured to change the welding current based on a position of a distal end of the wire a distance from which to a surface of a base metal varies periodically, in a case where the distal end of the wire is fed toward the base metal with periodical switching between a forward feeding period and a reverse feeding period.

摘要： In a method for detecting a deviation in arc-tracking welding, a deviation between a welding line and an actual welding position is detected in arc-tracking welding for performing welding tracking the welding line while performing a weaving operation of swinging a welding torch with respect to a welding direction. The method includes fitting a waveform expressed by a function repeated periodically in a period equal to a weaving period to a waveform of a welding current or a welding voltage and detecting a deviation in arc-tracking welding based on a fitted waveform.

摘要： A method for displaying an image of a surface of a tire includes: taking an image of a surface of a tire formed with a mark having a protrusion and a recess; acquiring waveform data from the taken image of the surface; creating a histogram from the waveform data; determining, based on the histogram, a first bin threshold to distinguish a surface luminance of the protrusion of the mark, and a second bin threshold to distinguish a surface luminance of the recess of the mark; and displaying the image of the surface of the tire including the mark on a screen by representing a region equal to or higher than the first bin threshold, a region lower than the first bin threshold and higher than the second bin threshold, and a region equal to or lower than the second bin threshold in the histogram in three attributes of color.
