Abstract: The invention relates to a process for fabricating a high-precision object made of at least one inorganic material, comprising the following steps: using a high-resolution photolithography process, employing X-rays or UV rays depending on the desired degree of precision, in a chosen direction Z, to form a negative mold, which does not deform at the microscale during the steps of the process, in a material able to withstand a step for forming the object by dry deposition and capable of either being removed without altering the object fabricated or being separated from said object; choosing, independently of the normal redox potential of its constituent elements, at least one inorganic material from the set of materials that can be deposited by dry deposition and that allow the object to be fabricated to meet its thermomechanical and environmental specifications; and forming, by means of the non-deformable negative mold, the object to be fabricated by dry deposition of said at least one inorganic material, ther

Abstract: The present invention relates to an orthopaedic lumbo-sacral corset obtained by the assembly of semi-rigid elements and of an inflatable pad. The orthopaedic lumbo-sacral corset according to the invention is made of two side half-shells of a semi-rigid plastic material, connected along the adjacent dorsal edges by a semi-rigid thin band forming a hinge adapted to be generally aligned with the spine of the wearer so as more clearly to orient the shells, with attachment and tightening structure between the adjacent front edges of the two half-shells and an inflatable lumbar pad forming two symmetrical pads relative to the axis. This orthopaedic lumbo-sacral corset is usable for the treatment of chronical lumbar diseases and difficult sciaticas.

Abstract: The device includes a support tube passing through the wall of the column of the microscope, whose inner end is supported on an inner structure of the microscope by a hemispherical surface. This is supported in the wall around the orientation axis and is connected to the sample-holder which it traverses by control means enabling the position of the sample-holder to be adjusted in the support tube along three axes of a reference dihedral. The control means comprise an annular diaphragm for suspending the sample-holder in the support tube close to the center of the support surface. Lever and push-rod connecting linkages of high stiffness enable the sample-holder to be tilted around the center of the diagram in two perpendicular planes.
