Process for producing semiconductor article

A process for producing a semiconductor article is provided which comprises the steps of bonding a film onto a substrate having a porous semiconductor layer, and separating the film from the substrate at the porous semiconductor layer by applying a force to the film in a peeling direction.

Method of detecting primer extension reaction, method of discriminating base type, device for discriminating base type, device for detecting pyrophosphate, method of detecting nucleic acid and tip for introducing sample solution

Convenient techniques for discriminating the base type in a base sequence of a nucleic acid are provided. The technique includes the step (a) of preparing a sample solution containing a nucleic acid, a primer having a base sequence that includes a complementary binding region which complementarily binds to the nucleic acid, and a nucleotide; the step (b) of allowing the sample solution to stand under a condition to cause an extension reaction of the primer, and producing pyrophosphate when the extension reaction is caused; the step (c) of bringing the sample solution into contact with the front face of a H+ hardly permeable membrane having H+-pyrophosphatase, which penetrates from front to back of the membrane, of which active site that hydrolyzes pyrophosphate being exposed to the front face; the step (d) of measuring the H+ concentration of at least either one of the solution at the front face side of the H+ hardly permeable membrane or the solution at the back face side of the H+ hardly permeable membrane, in a state where the H+-pyrophosphatase is immersed in the solution; the step (e) of detecting the extension reaction on the basis of the result of measurement in the step (d) ; and the step (f) of discriminating the base type in the base sequence of the nucleic acid on the basis of the result of detection in the step (e).

Multi-Axial Expandable Pedicle Screw and an Expansion Method Thereof

The invention disclosed a multi-axial expandable pedicle screw and an expansion method by using the same. Structure of the screw comprising a hollow screw being spherical shaped end connecting with an adapting piece, which is universal joint structure; an inner wall of the adapting piece connecting a lock bolt through screw threads; the hollow screw with sharp shaped on another end having a bore inside formed hollow structure in its entirety; the bore having taper shaped tip; expansion gaps uniformly setting up two, or three or four or more anterior fins on the hollow screw along its axial direction upward, prolonging from its tip to the bore; the inner needle is disposed in the bore. The invention can reduce the pedicle screw loose and even occurrence ratio of pull-out and increase the stability and reliability and reduce the failure rate of spinal surgeries at the same time. It is also easy to operate, and degree of expansion is of controllable level.
