Abstract: A belt conveyor comprising a drive device, a drive shaft connected to the drive device and rotated by the drive device, a driven shaft capable of rotating freely, and a first base member supporting the drive shaft at one end, a second base member supporting the driven shaft at one end, and an endless belt wrapped around the drive shaft and the driven shaft. The first and second base members can move relative to each other. The belt conveyor further comprises a bias device biasing the first and second base members away from each other, and a guide for guiding the second base member moving away from the first base member.

Abstract: A transparent liquid container bottle features a label with a tinted backside which imparts a tinted appearance to the contained liquid. The bottle has a cylindrical body, a hemispherical top and a base cup. The base cup may be tinted to match the backside of the label. The label covers only part of the cylindrical body, leaving an unlabeled section with a dimension 0.1 to 2.0 times, or 0.5 to 1.2 times preferably, the diameter of the body.

Abstract: A steering mechanism for motorcycles comprising upper and lower angular ball bearings having a swing angle of at least 50% and retained out of contact with one another by a pressure fitted retainer element. Friction rings are provided at the upper and lower ends of the steering column to permit reduction of pressure on the ball bearings, and the pressure on the upper and lower ball bearings is equalized by selective tightening of a nut mechanism attached to the upper end of the steering column.

Abstract: In an adhesive tape holder means a sheathing plate is mounted to one end of the means in vertically movable relation with respect to a cutting blade rigidly fixed adjacent to said end; the sheathing plate has a sliding element engaged with a cam mounted adjacent to said plate and having one end projected outwardly from one side of the means by a spring. When a pushing force is applied to said end, the cam is forced to move across the axis of the means to move down the sheathing plate, causing the blade to come out of the plate. When the force is released, the cam returns to its original position and simultaneously the sheathing plate moves up to sheathe the blade.
