Abstract: An objective of the present invention is to achieve greater efficiency in searches for illegal (illegitimate) content. The illegitimate content relates to content posted by an unauthorized user without a legitimate ownership of the content. An illegitimate content search device according to the present invention comprises: a content profile acquisition part for acquiring a profile including a posting history of illegitimate content posted by a user having posted candidate content being potentially illegitimate content; and a matching priority calculation part for calculating, on the basis of the profile, the priority of the candidate content with regard to determining whether a plurality of pieces of content is illegitimate content, and elevating the priority of the illegitimate content with a history of having posted the illegitimate content higher than if content without the history.

Abstract: A work vehicle steering control apparatus comprises a vehicle body (11), front wheels and rear wheels both of which can be steered respectively; a front-wheel steering cylinder (92) and a rear-wheel steering cylinder (94); a steering dial (72); a steering actuation controller (50); and a steering angle detector. The steering actuation controller (50) is configured in a manner such that when a steering operation is performed, and when the steering angles of one set of wheels are less than a predetermined angle (?1), the controller (50) controls the steering actuator to steer only the one set of wheels in response to the directional-change steering operation. When the steering angles of the one set of wheels are equal to or more than the predetermined angle, the controller (50) controls the steering actuator to steer the other set of wheels in a direction opposite to steering direction.

Abstract: A transmission includes a forward shift drum and an overlying and coaxial reverse shift drum. The drums are rotatable, but not longitudinally translatable with respect to each other. The drums each include lead grooves for guiding a shift fork pin therealong in portions of the grooves which overlap and intersect each other. When one of the lead grooves guides the shift fork pin into a gear position, the other lead groove serves as a stop, so that unintentional engagement of remaining gears with the drive shaft is prevented without the use of a separate special lock mechanism.

Abstract: A valve mechanism for a poppet valve of an internal combustion engine having a conventional cam and rocker arm control mechanism. Valve springs are positioned and compressed between the poppet valve and a valve spring retainer. The valve spring retainer moves relative to the engine head responsive to engine speed to further compress the valve springs with increased engine speed. A hydraulic controller operates through linkage employing a detent mechanism such that step-wise advancement of the valve spring retainer results to approximate an ideal engine speed versus valve spring force curve.

Abstract: An overrunning clutch device including a thrust ring slidably fitted in the driven clutch member and held connected with the driving clutch member and a set of spherical centrifugal weights mounted on respective radially flexible resilient arms of a weight retainer, which is fixed to the driven clutch member integral with a drive pinion. The centrifugal weights are held in rolling contact with a tapered annular guide surface of the thrust ring and act to force the latter and hence the driving clutch member away from the driven clutch member under centrifugal force when their speed of rotation exceeds a predetermined level.
