A seamless compression garment providing gradual steps of compression from top to bottom of the garment as worn, while following contours of the body of the wearer. Transition of the various steps of compression are seamless, without sewing. A compression garment top may include first, second, and third fabric portions disposed about a circumference of the garment, the first fabric portion having a high compression rating, the second fabric portion located above the first fabric portion and having a medium compression rating, the third fabric portion located below the first fabric portion and having a medium compression rating. A compression legging garment may include first, second, third or more fabric portions disposed about the garment, each fabric portion having a strategically designed compression rating. Where specifically located stretch resistance and material hold is desired, stretch fusing can be applied to certain segments of one or more fabric portions.

A shoe includes an upper having a heel portion that has a rear wall adapted to extend around the heel of a foot. At least one adjustment pad is attached loosely to the rear wall within the heel portion. The adjustment pad includes an intermediate part, first and second ends on two opposite sides of the intermediate part, a first surface confronting the rear wall, and a second surface opposite to the first surface. A strap passage unit is provided on the rear wall. A strap is attached to the adjustment pad, and passes movably through the strap passage unit. When the strap is pulled to move through the strap passage unit, the strap is tensed, and the adjustment pad is moved inward so as to abut against the foot in the shoe.

An upper has a front shell portion and a rear shell portion which includes a rear wall part, a front wall part, left and right wall parts that cooperate to confine a receiving space to receive the leg of the wearer. A leg support member is attached to an inner surface of the rear shell portion and extends from the rear wall part to the left and right wall parts. At least one of two end portions of the leg support member extends forwardly and outwardly from the rear shell portion and is manipulatable to tighten the leg support member around the wearer's leg so as to support and comfort the wearer's leg.

A coupled circulation tube for a ball screw unit. The tube is formed on a planar surface at one side of the ball screw bearing, each tube joined to two circulation holes. Each circulation tube is formed by coupling two symmetrical rigid metallic half tubes at recessed grooves and flanges interposedly arrayed one after another longitudinally along the wall of each half tube to form a resultant U shaped arcuate elbow tube for ball circulation such that it is firmly constructed with a desired toughness free from loosening, cracking or deforming by constant collision and abrasion of the rolling balls.

Ball screw nut is composed of an inner threaded nipple and an outer housing. The nipple is constructed with a hollow hard tubular metallic material to ensure the strength of the structure; while the outer housing where requires less strength is formed of a plastic material by ejection mold process so as to reduce the production cost and simplify the fabrication process. The nipple and the housing are conjoined together by screw engagement.

A spacer interposed between two adjacent balls formed into an elaborately designed cylinder like configuration which is able to minimize noise, vibration and frictional loss due to mutual collision and impact of the balls. The spacer is provided with a let through hole therein for further enhancing lubricating and cooling effect.

Disclosed herein is a leadscrew ball recirculation block with oil storing means wherein an cavity in the ball recirculation block which being not effectively used for circulating balls is utilized for storing lubrication oil. An oil exuding hole is provided to communicate with the oil stored cavity and a turning passage for balls so as to lubricate the moving balls. In order to prevent the lubrication oil remained at a standstill in a certain region in the cavity by its own gravity from failing to lubricate the balls, there is provided an oil containing element with a plurality of oil absorbing and distribution branches to lubricate the balls just passing by the turning passage. Furthermore, the ball recirculation block is formed of two pieces of plastic members bonded by supersonic wave bonding technique so as to achieve reduction of manufacturing cost and ensure perfect oil sealing effect of the ball recirculation block. With the result of such a construction, the usable lifetime of the ball recirculation block is prolonged and repeated replenishing of new oil is evaded. (FIG.,)

A twin headed flashlight includes a generally hollow, cylindrical body member with an interior body cavity sized to contain batteries which supply power to the flashlight. At one end of the cylindrical body, first and second flashlight head elements are mounted. The second flashlight head element is rotatably mounted to the cylindrical body such that the second flashlight head element can be rotated away or outboard from the axial centerline of the cylindrical body. In one mode of operation when the first and second flashlight head elements are juxtaposed near each other, a generally singular beam of light is emitted by the flashlight. In another operative mode when the second flashlight head is rotated outboard from the axial centerline, two divergent beams of light are emitted from the flashlight. Of course, the user can rotate the second flashlight head to a desired angular position within the maximum range of rotation (approximately 50 degrees from the axial centerline). In a specific embodiment, the first and second flashlight head elements include corresponding lenses that have respective, complementary mating edges. The mating lens edges are complementary to each other. Other lens shapes may be utilized.

This contrivance relates to a steering wheel lock and in particular to one including a female member provided with a stopper at one end, a plurality of notches at an intermediate portion, and a lock core at the other end, a male member fitted into the female member and having a plurality of notches opposite to the notches of the female member, a latch formed with a protuberance at both sides of its one end and a plurality of holes along its length and inserted into the male member until the latch is in contact with the stopper of the female member, and a ferrule engaged with the other end of the latch and kept in fixed position by a pin so that the latch may be pulled outwards until the protuberance of the latch is in contact with the ferrule thereby preventing the latch from detaching from the male member.
