A one-piece dental implant having a longitudinal axis comprises a head portion at a first end of the implant, a tip portion at a second end of the implant and a body portion between the head portion and the tip portion. The body portion has a first portion proximate the head portion with a plurality of longitudinal grooves substantially parallel to the longitudinal axis and a second portion proximate the tip portion having a substantially circumferential groove, wherein the outer diameter of the first portion is greater than the outer diameter of the second portion. The first and second portions are for being embedded in the jaw bone. The dental implant is preferably dimensioned to conform to the natural shape of the cervical ⅓ of the root of the tooth being replaced, and to the natural relationship between the cemento-enamel junction of the tooth being replaced and to minimize adverse immunological responses by the jaw bone during healing, thereby improving the aesthetic appearance of the implant and prosthetic tooth attached thereto. A dental implant and prosthetic tooth system is also disclosed, wherein the prosthetic tooth conforms to the shape of the cervical ⅓ of the crown of the tooth being replaced. A method for implanting a dental implant through use of a reference, is also disclosed.

An athletic shoe has a sole composed of an inner layer and an outer layer that comes into contact with the ground surface. In the athletic shoe, a plurality of downward projecting projections are formed on the lower surface of the outer layer as parts of the outer layer, and a ring-shaped flange portion is formed as a part of the outer layer to surround the corresponding projection. The ring-shaped flange portion slants upward from its outer edge toward the inner edge. When a downward pressure greater than a predetermined value acts onto a portion where the projection and the corresponding flange portion are formed, the flange deforms in order to move the projection downward. In another athletic shoe, a plurality of projections is formed on the outer surface of a sole, and a depression is formed in the outer surface of the sole in the vicinity of each of the projections. The athletic shoe is excellent in terms of performance in gripping a soft ground surface such as a lawn surface and the easiness of walking on hard surfaces such as a paved path or a floor.

A latch mechanism is disposed at opposite ends of the base for releasably securing the tank assembly with the base. The base houses a liquid pump and air compressor. A manual selector is mounted at the base and has separately selectable positions including a first position in which the pump is connected with the water tanks, and a second position in which the pump is connected with the solution tank. A spray hose is coupled from the pump for directing either of the water or solution when the pump is activated.

Tubes within a radiant heating section of a coking furnace are arranged differently than in a single vertical column and connected together in a simple, planar serpentine pattern. The tubes are arranged in a plurality of offset or staggered vertical columns. This arrangement permits the upper tubes to be close to the radiant heat source and allows the tube bends connecting adjacent tubes to be of greater radius, so that the pressure at which the feedstock is passed through the tube bundle can be lower allowing more vaporization of the cracked process fluids.

A propulsion system 2 for a waterborne vessel 4 comprises a hull structure 6, typically for a full or semi planing boat. The propulsion system 2 comprises a pod housing 8 having a front end 10 and a rear end 12, a propeller 14 and a propeller shaft 16. The propeller 14 is disposed externally at the front end 10 of the pod 8 and is rotatable about a longitudinal axis 18 of the propeller shaft 16, the propeller shaft 16 being drivingly connected to drive means. The drive means comprises a transmission unit 20 and a power unit 22 in the form of a diesel engine. In FIG. 1 the diesel engine is shown disconnected from the transmission unit 20.

A multi-layer gate stack structure of a field-effect transistor device is fabricated by providing a gate electrode layer stack with a polysilicon layer, a transition metal interface layer, a nitride barrier layer and then a metal layer on a gate dielectric, wherein the transition metal is titanium, tantalum or cobalt. Patterning the gate electrode layer stack comprises a step of patterning the metal layer and the barrier layer with an etch stop on the surface of the interface layer. Exposed portions of the interface layer are removed and the remaining portions are pulled back from the sidewalls of the gate stack structure leaving divots extending along the sidewalls of the gate stack structure between the barrier layer and the polysilicon layer. A nitride liner encapsulating the metal layer, the barrier layer and the interface layer fills the divots left by the pulled-back interface layer. The nitride liner is opened before the polysilicon layer is patterned. As the requirement for an overetch into the polysilicon layer during the etch of the metal layer, the barrier layer and the interface layer is omitted, the height of the polysilicon layer can be reduced. The aspect ration of the gate stack structure is improved, the feasibility of pattern and fill processes enhanced and the range of an angle under which implants can be performed is extended.
