This invention provides an oil-hydraulic vehicle whose driving force can be adjusted finely and which can be run smoothly and comfortably. The oil-hydraulic vehicle comprises a wheel-driving meansfor driving a wheel, which includes an oil-hydraulic motorto drive the wheeland a meansfor controlling the rotational frequency of the oil-hydraulic motor. The oil-hydraulic motorincludes an output shafton which the wheelis mounted and a plurality of oil chambers-. Each oil chamber contains (i) a driving cogwheelwhich is mounted on, and drives, the output shaftand (ii) a driven cogwheelwhich engages with the driving cogwheel. The meansfor controlling the rotational frequency of the oil-hydraulic motorincludes a housingwith a circular rotor chamberin it and a rotorfitted in the circular rotor chamberfor free rotation.

Oil-hydraulic vehicle

An oil-hydraulic vehicle comprising (i) at least one oil-hydraulic pumpdriven by an engine E, an input shaft of said oil-hydraulic pump being directly coupled with a crankshaft C of the engine, (ii) at least one oil-hydraulic motorto drive at least one wheelin both forward and backward directions, (iii) an oil-hydraulic circuitto connect said oil-hydraulic pumpand said oil-hydraulic motor, and (iv) at least one flow control valveprovided between said at least one oil-hydraulic pumpand said at least one oil-hydraulic motor. Said at least one flow control valvehas (i) a first changeover position where the valvereturns the oil, which is fed from said oil-hydraulic pumpto the valve, to said oil-hydraulic pump, (ii) a second changeover position where the valvefeeds the oil, which is fed from said oil-hydraulic pumpto the valve, to an inlet of said oil-hydraulic motor, and (iii) a third changeover position where the valvefeeds the oil, which is fed from said oil-hydraulic pumpto the valve, to an outlet of said oil-hydraulic motor

A building panel formed by extruding a mixture of wooden and/or bamboo powder and a binding agent. Its panel body comprises (i) a door panel extending in the direction of extrusion, (ii) a pair of longitudinal frame members formed in the direction of extrusion on the right and left sides of the door panel, and (iii) a panel strip formed in the direction of extrusion at the center of the door panel. The door panel, the paired longitudinal frame members, and the panel strip are formed as a single piece. The door panel and the panel strip are cut short at their upper and lower ends so that the upper and lower ends of the longitudinal frame members stand out beyond the cut ends of the door panel and the panel strip, the standing-out portions constituting tenons.

Building panel

An anticancer drug of which the main ingredient is bamboo powder. In particular, the bamboo powder is of lower no-branch culm portions of three-year-old and older bamboos, or is of bamboos cut down during the period of three months before the season of bamboo shoots; and pumpkin seed powder, garlic powder, powdered cheese, wheat flour, and water are added to the bamboo powder to make a mixture thereof, and the mixture is allowed to mature.
