An electromagnetic pedicle awl utilizes a tightly focused time-varying magnetic flux to create a localized electromotive force (EMF) near the tip of a pedicle awl. The localized EMF creates localized eddy currents in nearby nerves which in turn excite ionic nerve channels, the excitation being detected by an electromyographic recording device. In comparison to the electrically stimulated pedicle awl of the prior art, the electromagnetic pedicle awl only excites nerves directly in front of and directly to the side of the tip. The electromagnetic pedicle awl is comprised of a tapered awl or drill tip in combination with a solid core surrounded by a solenoid. A pulsed electric current source drives the solenoid to create a time-varying magnetic field in the vicinity of the tapered tip. The awl or drill tip may be stationary with respect to the solenoid or it may rotate. The electromagnetic pedicle awl in combination with an EMG detector connected to a patient is very sensitive to the pedicle hole position with respect to adjacent nerves and reduces false placement failure.

In a multi-piece solid golf ball comprising a solid core and a cover of two inner and outer layers enclosing the solid core and formed on the surface with a plurality of dimples, the solid core in its entirety has a hardness distribution falling within the range of JIS-C hardness 50-85, the difference between maximum and minimum JIS-C hardnesses in the solid core falls within 5%, the cover inner layer has a JIS-C hardness of 70-90, the cover outer layer has a JIS-C hardness of 60-80, the sum of high-speed region dimple operative volumes HDOV of respective dimples is 170-310, the sum of low-speed region dimple operative volumes of respective dimples LDOV is 200-310, and the overall dimple volume is 260-360 mm<3>.

In a multi-piece solid golf ball comprising a solid core consisting of a center core and an outer core, an inner cover layer and an outer cover layer, the solid core is molded from a rubber composition comprising a base rubber composed of (a) a polybutadiene having a high cis-1,4 content, a minimal 1,2 vinyl content and a viscosity η of up to 600 mPa·s at 25° C. as a 5 wt % toluene solution, being synthesized using a rare-earth catalyst, in combination with (b) another diene rubber, (c) an unsaturated carboxylic acid, (d) an organosulfur compound, (e) an inorganic filler, and (f) an organic peroxide; and the center core has a specific JIS-C hardness on its center and a specific JIS-C hardness on its surface and the certain difference, the outer core is harder than the surface hardness of the center core, the cross-sectional hardness of 1 mm outside from the border between the center core and the outer core is a specific range on JIS-C hardness, the surface of the outer core has a specific JIS-C hardness, the inner cover layer has a specific Shore D hardness; the outer cover layer has a specific Shore D hardness; and the outer cover layer has a lower Shore D hardness than the inner cover layer. This combination of features gives the ball a good, soft feel upon impact and an excellent spin performance that provides increased distance.

A solid golf ball is composed of a solid core and a cover of one or more layers which encloses the core and has on a surface thereof numerous dimples. The solid core has a diameter of 38.7 to 39.6 mm and a deflection hardness of 3.0 to 4.0 mm. The cover has a Shore D hardness of 59 to 70 and has 313 to 371 dimples formed thereon. The ball has an initial velocity of at least 76.8 m / s, a coefficient of lift (CL) when hit of at least 0.165 at a Reynolds number of 70,000 and a spin rate of 2,000 rpm, and a coefficient of drag (CD) when hit of not more than 0.230 at a Reynolds number of 180,000 and a spin rate of 2,520 rpm. The golf ball has a carry which is long enough to make the ball advantageous for competitive play, in addition to which it has a good feel when hit and excellent durability to cracking with repeated impact.

A dynamic longitudinal connecting member assembly includes an anchor member having an integral or otherwise fixed elongate core of circular or non-circular cross-section. The core is pre-tensioned and extends through at least one elastic spacer and at least one outer sleeve. The anchor member and the outer sleeve each attach to at least one bone anchor. In operation, the core is held in tension by the spacer.

An oral composition comprising minicapsules wherein the minicapsules comprise one or more therapeutic or prophylactic substances in a liquid, semi-liquid, or solid core. The minicapsules have release profiles to release the substance in an active form at one or more sites along the gastro-intestinal tract to maximise absorption and / or therapeutic efficiency.

The invention provides a solid golf ball having a solid core and a cover layer that encases the core and has an outermost layer on an outside surface of which are formed a plurality of dimples. The solid core is formed of a rubber composition composed of 100 parts by weight of a base rubber that includes 60 to 100 parts by weight of a polybutadiene rubber having a cis-1,4 bond content of at least 60% and synthesized using a rare-earth catalyst, 0.1 to 5 parts by weight of an organosulfur compound, an unsaturated carboxylic acid or a metal salt thereof, an inorganic filler, and an antioxidant. The solid core has a deformation, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of 2.0 to 4.0 mm, and has a specific hardness distribution. The cover layer is formed primarily of a polyurethane material and has a thickness of 0.5 to 2.5 mm, a Shore D hardness at the surface of 50 to 70 and a flexural rigidity of 50 to 300 MPa. The golf ball has a deformation, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of 2.0 to 3.8 mm. The solid golf ball is advantageous overall in competitive use.

A multi-piece solid golf ball has a solid core obtained by molding and vulcanizing a rubber composition which includes (A) a base rubber containing a polybutadiene synthesized using a rare-earth catalyst, (B) an unsaturated carboxylic acid and / or a metal salt thereof, (C) an organic sulfur compound, (D) an inorganic filler and (E) an organic peroxide. The core is enclosed within a mantle of one or more layer which is made primarily of a thermoplastic resin and has a Durometer D hardness of 30 to 70. The mantle is enclosed within a cover which is made primarily of a thermoplastic polyurethane and which has a Durometer D hardness of 40 to 60 that is lower than the Durometer D hardness of the outermost layer of the mantle. This construction provides the golf ball with an outstanding rebound.
