A forklift includes a vehicle and a cargo handling device. The cargo handling device includes a mast, a lift bracket, and a pair of forks that includes claw portions, the forks being separated from each other in a vehicle width direction. The vehicle includes a vehicle main body, and a pair of straddle legs that is provided such that the straddle legs extend to the front side from a lower portion of the vehicle main body and the cargo handling device is interposed between the straddle legs in the vehicle width direction and that supports the mast such that the cargo handling device is movable forward and backward between an advance position and a retreat position, and front ends of the claw portions are positioned behind front ends of the straddle legs when the cargo handling device is at the retreat position.

A machining position correcting device is configured to be applied to an electrochemical machining device configured to make an electrolyte flow out of a distal end part of an electrode bar extending along an axis while rotating the electrode bar about the axis to electrochemically machine a material to be machined in a range from the distal end part of the electrode bar. The machining position correcting device includes a position detector configured to detect a rotational position of a feature point of the electrode bar.

Machining position correcting device and electrochemical machining device

A measurement system is for measuring positions of a plurality of subjects by using an ultrasonic testing sensor. The measurement system includes an ideal arcuate waveform creation unit configured to create, for each of the subjects, an ideal arcuate waveform of a measurement result of the ultrasonic testing sensor based on machining position information on the subject; a measurement arcuate waveform creation unit configured to create a measurement arcuate waveform based on the measurement result; a position estimation unit configured to collate the ideal arcuate waveform and the measurement arcuate waveform with each other to estimate a position of the subject from the measurement arcuate waveform determined to correspond to any ideal arcuate waveform; and an antiphase waveform addition unit configured to add, to the measurement arcuate waveform, a waveform in antiphase to the measurement arcuate waveform with which the position of the subject has been estimated.

Provided is an underwater floating-type ocean current power generation device whereby cyclical directional vibration of a floating body of the ocean current power generation device, caused by shadow moment, can be suppressed. An underwater floating type ocean current power generation device includes ocean current power generation device main bodies, each including a rotor of a power generator housed in a nacelle, and a structure. The rotor is configured to be driven by a rotary blade protruding outward from the nacelle. A twin drum floating body capable of floating underwater is constituted by the structure and the ocean current power generation device main bodies joined to the left and right of the structure. The underwater floating type ocean current power generation device is moored to an ocean floor by a mooring rope.
