Abstract: 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.

Abstract: A coupling portion that is coupled to a mast that supports a fork and has a mechanism that moves the fork in a vertical direction, the coupling portion disposed on each of both ends in a width direction of the mast, a rail that is disposed on a straddle leg disposed on an outside in the width direction of the mast and extending in a direction where the fork extends, the rail moving the coupling portion in the direction where the fork extends, and a drive unit that is disposed on the straddle leg and moves the mast along the straddle leg are included.

Abstract: A computation device includes a first specifying unit configured to, based on a distance between a vehicle configured to autonomously travel and a pallet to be handled at a position on a first route on which the vehicle travels, specify a second route on which at least one of the vehicle and another vehicle different from the vehicle travels during material handling work that is related to the pallet and performed after the vehicle has traveled on the first route.

Abstract: A turbocharger and a method of manufacturing a floating bush with which noise can be reduced, and the rotation speed can be increased. In a turbocharger in which a rotating shaft having a circular cross-section and connecting a turbine rotor and a compressor rotor is supported in a freely rotatable manner, at two axially separated positions via floating bushes, by an inner circumferential surface disposed so as to surround the rotating shaft in a bearing housing, an inner circumferential surface of each of the floating bushes has a non-circular shape in which the curvature of the cross-sectional shape varies in the circumferential direction.

Abstract: A bearing for a turbocharger includes a bearing housing having a bearing portion of the turbocharger, a rotor shaft penetrating the interior of the bearing housing, a floating bush interposed between the bearing portion and the rotor shaft and configured to supply lubricating oil to an outer peripheral surface and an inner peripheral surface via an oil supply hole interconnecting the outer and inner peripheral surfaces, and a pressure receiving part for generating pressure by catching the flow of the lubricating oil, which is provided at a position on the inner peripheral surface of the floating bush not communicating with the oil supply hole.

Abstract: A communication system is allowed to use one or more electronic devices connected with a device interface of a server system by communicating with the server system via a network. The communication system or the server system notifies to a user a correspondence relation between items, including those identifying the electronic device and a port connected with the electronic device.

Abstract: An object is to provide a cylinder driving device of a wind-power generation system capable of appropriately controlling a pitch angle of each rotor blade at a time of power failure with a simple configuration. The present invention achieves the object by including a piston connected to the rotor blade; a cylinder that moves the piston by a hydraulic pressure; an urging member that urges the piston in one direction; an accumulator that is connected to the cylinder, and supplies hydraulic oil urging the piston in an opposite direction to a direction where the piston is urged by the urging member to the cylinder; and an on/off valve that controls opening or closing of a channel between the accumulator and the cylinder.

Abstract: A wind power generator is provided which is configured to take a measure against a decrease in oil temperature which measure requires no new large-capacity power source. A wind power generator including a hydraulic pump configured to be stopped when a wind turbine is shut down further includes a bypass channel branching off from an discharge side channel of the hydraulic pump and connected to an oil tank, an electromagnetic valve provided in the bypass channel and opened when the hydraulic pump is started, a temperature sensor configured to detect the oil temperature of hydraulic operating oil, and a controller configured to carry out pump inching after the hydraulic pump has been started, to raise the temperature of the hydraulic operating oil to a predetermined value.
