Abstract: A tread pattern for a vehicle track, such as an endless track for earth-moving equipment, comprises a plurality of blocks. Each block includes two lateral traction portions extending in substantially opposite directions. The two lateral traction portions are longitudinally aligned and each define a pair of walls defining a plurality of steps. In some examples, each lateral traction portion may define an L-shape. For example, the lateral traction portions of each block may define a protrusion to define the “L” shape, and, in some examples, the protrusions may extend in opposite longitudinal directions. In some examples, the lateral traction portions of each block may be the same shape, where one lateral traction portion may be oriented at about 180 degrees relative to the other lateral traction portion.

Abstract: A tread pattern for a vehicle track, such as an endless track for earth moving equipment, comprises a plurality of blocks. Each block includes two lateral traction portions extending from a center traction portion in substantially opposite directions. The two lateral traction portions are longitudinally aligned. In some examples, each lateral traction portion may define a T-shape. For example, the lateral traction portions of each block may define a protrusion to define the “T” shape, and, in some examples, the protrusions may extend in opposite longitudinal directions. In some examples, the lateral traction portions of each block may be the same shape, where one lateral traction portion may be oriented at about 180 degrees relative to the other lateral traction portion.

Abstract: A flex pin includes a compressible member disposed between first and second rigid members configured to be installed in a tooth and shank assembly. The first rigid member includes a locking recess defined by a front wall, a locking major surface, and a back gradation defining at least one step. At least one of the first or second rigid members includes a bonding recess configured to receive a portion of the compressible member.

Abstract: The present invention provides a method for collecting/transporting a medical capsule by holding the medical capsule using an endoscopic apparatus comprising: an endoscope having an inserting section to be inserted in a body cavity with a distal end including an observation section to observe a subject and an suction opening; a sucking device in communicated with the suction opening; and a generally cylindrical hood member which is attached to the distal end of the inserting section, the method comprising: a sucking step of making an inside of the hood member vacuum by actuating the sucking device to suck the inside of the hood member through the suction opening; and a holding step of attracting and holding the medical capsule to the hood member sucked by the sucking step.

Abstract: The endoscope applicator according to the present invention allows lubricant to be supplied uniformly to the entire inner surface of the endoscope applicator without increasing the diameter of the endoscope applicator because the lubricant supply path is laid on the outer surface of the endoscope applicator extending from the base end portion to the tip portion of the endoscope applicator and a plurality of openings are formed in the lubricant supply path and endoscope applicator at predetermined intervals in such a way that their opening areas of the opening increase from the base end portion to the tip portion. Moreover, the endoscope apparatus according to the present invention can improve the maneuverability of the insert portion and applicator during pull-in operation. Furthermore, the endoscope apparatus according to the present invention makes it possible to determine pull-out force quantitatively.

Abstract: A balloon attaching jig is constituted by a ring member and a pair of nail members. After the insertion of the pair of nail members into an attaching hole of a balloon, the leading end of an insertion portion of an endoscope is pushed into an opening of the ring member. The diameter of the pair of nail members is expanded by a pushing-in force of the leading end of the insertion portion generated during this pushing in. As a result of this, the leading end of the insertion portion is inserted into the attaching hole of the balloon and hence the balloon can be easily attached to the leading end of the insertion portion of the endoscope.
