Title: Method and device for placing dental implants
Inventor: TARDIEU PHILIPPE
IPC: A61C8/00
Filed: 2003-02-28
Granted: 2012-03-20
Abstract: The invention relates to a method and device for placing implants (1) using a surgical template (11) which is made from tomographic cuts in the patient's jawbone (7).  According to the invention, step drills (4) and calibrating drills (5), having a single standard diameter for each type of implant (1), are guided through drill bushings (18) which are inserted into bores (15) in the template (11) in order to produce any drilling sequence corresponding to an implant plan. The penetration depth of the drills (4, 5) is controlled by the height of the bores (15) or by the drill rings (21). The aforementioned template (11) bores (15) serve as a guide for the precise placement of the implants (1) owing to the adapted implant supports (3). Moreover, washers (23), which are mounted around the implant supports (3), limit compression in relation to the implants (1) while said implants are being placed (20). The above-mentioned characteristics serve to limit the required number of drills (4, 5) and implant supports (3) to the longest models only.  The inventive method and device are particularly suitable for computer-assisted implantology systems

Abstract: A micro-electro-mechanical (MEMs) mirror device for use in an optical switch is disclosed. A "piano"-style MEMs device includes an elongated platform pivotally mounted proximate the middle thereof by a torsional hinge. The middle portion of the platform and the torsional hinge have a combined width less than the width of the rest of the platform, whereby several of these "piano" MEMs devices can be positioned adjacent each other pivotally mounted about the same axis with only a relatively small air gap therebetween. In a preferred embodiment of the present invention electrostatic charges, which build up on exposed dielectric surfaces causing the mirror's angular position to drift over time, are minimized by positioning the hot and ground electrodes at different levels separated by a vertical surface, and placing the dielectric material on the vertical surface.

Abstract: Cooling structure of gas turbine combustor in which cooling medium flows through grooves in wall is improved so that adjustment of flow velocity, pressure loss and heat transfer rate of cooling medium flow in the wall becomes possible and cooling effect thereof is enhanced. Wall of combustor tail tube is made in double structure in which outer plate (1) and inner plate (4) are jointed together being lapped one on another . The outer plate (1) has air inlet hole (3) and groove (2) formed therein . The groove (2) is closed by jointing of the inner plate (4) to the outer plate (1).      The inner plate (4) has air outlet hole (5) formed therein.      The groove (2) communicates with the air inlet hole (3) and the air outlet hole (5). Cross sectional shape of the groove (2) is changed two-dimensionally or three-dimensionally such that width enlarges toward the hole (5) from the hole (3) or depth is constant or changed in tapered form. Cooling air flows into the groove (2) from the air inlet hole (3) of tail tube surface to flow toward both sides along the groove (2) for cooling of the wall. The air is thereby heated to expand to increase flow velocity and pressure loss, but flow passage enlarges toward the hole (5) and flow velocity is suppressed and pressure loss is reduced.

Abstract: A throttle body 12 is connected to a rear portion of a cylinder head 10 of an air-cooled engine 5, and a fuel pump 23 is disposed in front of the engine 5. The fuel pump 23 is such as to be disposed below a fuel tank 6 in such a manner as to be separated therefrom and to be integrated with an auxiliary tank. Fuel is sent under pressure from the fuel pump 23 to the throttle body 12 via a fuel feed tube 13, and surplus fuel is returned to the integrated auxiliary tank, consequently, no piping for return fuel being required. Vapor generated in the fuel pump 23 returns to a space above a fuel level resulting when the fuel tank 6 is filled up via an exclusive return tube 25 and is, therefore, prevented from mixing into fuel.

Axial load on the rotor shaft is directed through a first bearing, through the first housing to the stator and through the second housing to a motor support. Heat is dissipated using low-loss electrical steel, one or more air movers and air passages through the motor. Preferably a stator profile enables the air passages to be formed through the stator's lamination stack. Optionally air is routed through passages between the coils and through air passages along the air gap and radially through passages between an upper and a lower stator. A first self aligning bearing adapts to misalignment between the first housing and the shaft and a second bearing is provided with transverse movement. Preferably, the frameless motor is adapted for support to a wellhead for driving a downhole rotary pump and a rotary rod string.

Abstract: When manufacturing a seamless pipe by carrying out elongation rolling and sizing on a mother tube for forming a seamless pipe, the occurrence of portions of thickness variation in the seamless pipe is suppressed by previously identifying the portions of wall thickness variation where the thickness varies in the circumferential direction of the seamless pipe, and carrying out elongation rolling so that the thickness of the portions of the mother tube corresponding to the portions of wall thickness variation of the seamless pipe are different in thickness at the completion of elongation rolling from that of other portions of the mother tube. As a result, local variations in wall thickness in the circumferential direction of a seamless pipe are prevented.
