A suture anchor includes a threaded anchor body having a first central bore in communication with a second central bore. The suture anchor includes an internal eyelet formed of a loop disposed at least partially inside the first central bore. The ends extending from the loop are tied together to form at least one knot which is housed in the second central bore provided at the distal end of the anchor body. The knot increases the pullout strength of the suture even in soft bone, provides increased suture fixation, and eliminates the anchor “pull back.”

A sliding guide rail assembly (20, 20a, 20b) is provided for slidably mounting a drawer or equipment (10) within a cabinet or chassis. The rail (33a) is formed from a sheet metal into a T-shaped section onto which a sliding means (40, 40a, 40b, 40c) fits and slides smoothly thereon. Guides (50, 120, 150, 160) also formed from a sheet metal into C-sections fitting over the sliding means (40, 40a, 40b, 40c) and operable to slide smoothly therewith. This enables the drawer / equipment mounted on the slide (20, 20a, 20b) to be drawn in and out with little effort or wear and tear.

A tightening system can be used with a helmet or other wearable article. The tightening system can have a forehead strap that is space apart from a yoke, which can be configured to engage a back side of a wearer's head. A lace can extend between the forehead strap and the yoke and a tightening mechanism can be configured to adjust tension on the lace. One or more intermediate tenders can engage the lace in the gap between the forehead strap and the yoke so that the lace path between the forehead strap and the yoke is non-linear. The yoke can have a height adjustment mechanism. The tightening mechanism can be configured to provide a clicking sound during rotation in both the tightening direction and the loosening direction. The tightening mechanism can include a rotation limiter to prevent over-tightening and / or over-loosening of the tightening mechanism.

A method and device provides features for the temporary “parking” of sutures with respect to a cannula. In the preferred embodiments the features are slots that maintain tension on, and orientation of, sutures placed therein. The slots or features may be integral with the cannula or part of a separate device which may be removably affixed to the external portion of a cannula. The invention eliminates the multiple steps inherent in current suture management techniques for arthroscopic procedures, particularly rotator cuff repair and assists in tensioning / advancement of tissue into its repair site.

A cervical spine fixator and a screwdriver used therefore is disclosed wherein the fixator comprises plates (12, 212) for being adjoined to a cervical spine fixation region and a plurality of screws (14, 214). The plurality of screws are fixedly inserted into a patient's cervical spine and simultaneously coupled to the plates, wherein an adjacent region coupled with the screws in the plates is fixed with screw head fixture members (16, 216) having a protruder, which is deformed under the effect of pressure by a screw head when the screws are inserted and returns to their position of origin when the screw head is completely accommodated into the plates to be hitched by the screw head. The plates are formed thereon with receiving grooves (22, 222) for accommodating the screw head and the screw head fixture member. The receiving grooves are formed with openings into which the screws are inserted and a recess into which the screw head is received. The screw (214) formed with a groove of concaved curvature is installed or removed by a screwdriver (230) formed with a protruder of convex curvature, such that it is easy to manufacture, and the thickness of the plates is reduced, thus eliminating the feeling of a foreign substance after a surgical operation.

The present invention relates to a ceramic sheet having uniform quality over its entire surface with a decreased number of defects such as foreign matters and flaws. When the ceramic sheet was divided into sections of 30 mm square or smaller, each divided section has 5 or less defects detected based on an image obtained with a charge coupled device (CCD) camera. The present invention also relates to a method of producing the ceramic sheet. In this method, a green sheet or a calcined sheet mainly including spherical ceramic particles having an average particle diameter of 0.1 to less than 5 μm was used as a spacer. By using this spacer, the green sheet for ceramic sheet slides smoothly on the spacer surface when it shrinks in baking, and the friction resistance between the green sheet for ceramic sheet and the spacer is lowered. In this manner, the method of the present invention can mass-produce the above-described high quality ceramic sheets.

A stabilizing assembly includes a retaining device settled between a drawable carrier and a cabinet body for preventing the drawable carrier from swinging in sliding. The retaining device includes two rails fixed to two opposite laterals of the drawable carrier. Each of the rails has a rack. Two gears engaging with the racks are connected by a rod and rotate simultaneously. Two bushes at two ends of the rod are received in supporting seats that are fixed on the cabinet body or the drawable carrier and allowed to shift vertically. Two stop portions, as a stop unit, each extending from the rail toward a side of the rod opposite to another side of the rod facing the rack on the rail are closely adjacent to the retained portions so that the bushes are retained and stopped by the stop unit, and disengagement between the racks and the gears is prevented.

In the communication terminal having a first body and a second body, a driving unit includes a motor and a pinion connected to the motor. A first hinge has a rack gear meshed with the pinion and a travel-enlarging member connected to the rack gear. A second hinge has a contact member protruded therefrom to contact the travel-enlarging member. Rotation of the pinion in response to the drive force of the driving unit is converted into a linear movement of the rack gear, and a distance of the linear movement of the rack gear is enlarged by means of the travel-enlarging member, so that the second body fixed to the second hinge is slid to an enlarged travel distance.

An automobile door checker includes a check plate, a shoe holder housed in a case, a shoe that is held by the shoe holder and the shoe slides on the check plate accompanying relative movement between the case and the check plate, and a check spring that resiliently urges the shoe holder toward the check plate in order to press the shoe against the check plate. The shoe is axially supported in the shoe holder so that the shoe can swing from a neutral position to forward and backward swing limits. The shoe is provided with return-to-neutral means for exhibiting a return force that makes the shoe return to the neutral position. The contact area between the shoe and the check plate is arranged so that the frictional force in the contact area becomes the smallest when the shoe reaches the shoe swing limits.

A normally open hydraulic control valve includes: a linear solenoid unit; a spool driven by an output force of the linear solenoid unit to move forward; a valve body in which the spool is fitted; and a return spring for biasing the spool in a retreating direction. The valve body includes: a reaction force oil chamber for introducing hydraulic pressure, which presses the spool in a direction against a biasing force of the return spring, from the output port; and a damper oil chamber which suppresses vibration of the spool. The damper oil chamber is adjacent to the reaction force oil chamber with the third land portion of the spool therebetween. A slide gap which leaks and supplies oil from the reaction force oil chamber to the damper oil chamber is provided between the third land portion and the valve body. Thus, it is possible to quickly supply the oil to the damper oil chamber at the early stage of the operation without restriction on the arrangement, and to prevent delay in operation of the damper oil chamber.
