Abstract: 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 means 40 for driving a wheel 31, which includes an oil-hydraulic motor 45 to drive the wheel 31 and a means 41 for controlling the rotational frequency of the oil-hydraulic motor 45. The oil-hydraulic motor 45 includes an output shaft 45s on which the wheel 31 is mounted and a plurality of oil chambers 45a-45e. Each oil chamber contains (i) a driving cogwheel 46 which is mounted on, and drives, the output shaft 45s and (ii) a driven cogwheel 47 which engages with the driving cogwheel 46. The means 41 for controlling the rotational frequency of the oil-hydraulic motor 45 includes a housing 42 with a circular rotor chamber 42h in it and a rotor 43 fitted in the circular rotor chamber 42h for free rotation.

Abstract: 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.

Abstract: 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.
