Title: Positioning device for cylindrical drum
Inventor: NAKANO NAKAYA
IPC: G03G5/05
Filed: 1990-06-22
Abstract: PURPOSE:To prevent the rubbing contact and the scratch of the cylindrical drums even when the cylindrical drums are continuously transported by constituting gripping parts of freely revolving rollers having the axial center orthogonal with the longitudinal section of the cylindrical drums. CONSTITUTION:The outside surfaces of the parts for connecting the cylindrical drums 1 to each other are gripped from the outside to correct steps. Then, the outside surfaces of the adjacent cylindrical drums 1 are positioned flush with each other with good accuracy. In addition, the scratch of the entire part in the longitudinal direction of the cylindrical drums is obviated at the time of correcting the steps. The gripping parts 12 of the gripping means 10 are the freely revolving rollers 15 having the axial center orthogonal with the longitudinal section of the cylindrical drums 1. Even if the cylindrical drums 1 are already risen when the cylindrical drums 1 are gripped by the rollers 15, the rollers 15 are driven according to the rise thereof and, therefore, there is no rubbing contact to be generated when the positions of the gripping parts 12 of the gripping means 10 are fixed. The scratch on the outside surface of the cylindrical drums 1 is thus prevented.

IPC: B62M1/24
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To attain inexpensive and light devices by simplifying a structure for reducing the number of parts, and smooth pedaling operation. SOLUTION: Torque is transferred to a rear wheel 2 using a sprocket 26 and a chain 27. The torque of a pedal lever 22R is transferred to the sprocket 26 through a crank lever. The oscillation fulcrum of the pedal lever 22R is not fixed and moves to the right and left in a sliding part 40R, thereby simplifying the structure of a torque transferring mechanism 20 to the rear wheel 2. When the pedal lever 22R is depressed, the oscillation fulcrum moves to the right and left, thus it is possible to rotate a pedal 23R smoothly even if the rotational movement locus of the pedal 23R differs between the first half period (period of stepping-down) and the latter half period (period of steppingup).

Abstract: PURPOSE:To directly and accurately detect the cultivableness of a farming land by allowing a hammer to collide with a prescribed soil sample to break it and measuring the cultivableness from the ratio of energy required for the breaking processing to the total surface area of the broken sample. CONSTITUTION:A wedge type hammer 1 is lifted in the clockwise direction and a holding balance 12 is operated to set up the handle part 21 of the hammer 1 on the balance 12. Under above state, a soil sample formed like a fixed circle is set up on the recessed part 7 of a soil sample setting board 2 and a cover 13 is applied to the sample. Then, the weight 22 of the hammer 1 is dropped by operating a holding means 10. The hammer 1 is rotated around the supporting shaft 5 and a cutting edge part 23 collides with the soil sample to break it. An indicator 6 is rotated up to a stop point together with the hammer 1 and temporarily stops together with the hammer 1. The stop position indicates the maximum vibration position of hammer 1. The quantity of energy required for the breaking operation is measured based upon an angular difference between the maximum position and the maximum vibration position for free oscillation. Since the broken soil sample is accumulated on a base 3 due to the cover 13, the total surface area can be calculated and the quantity of energy required for the formation of a unit area can be obtained.
