专利名称：SCREWING METHOD OF MACHINE SCREW 发明人：WATANABE JUN申请号：JP27643887申请日：19871031公开号：JPH01120409A公开日：19890512专利内容由知识产权出版社提供摘要：PURPOSE: To prevent fall over of a small screw by inserting the top part of the small screw into a guide hole, standing the small screw upright and then driving it in. CONSTITUTION: A top screwing part 1a of a small screw 1 is inserted into a guide hole 4b. As the diameter D3 of the guide hole 4b is bigger than or equal to the outer diameter D2 of the screwing part 1a of the small screw 1, it is completely to be inserted into the hole, so the small screw 1 can reliably stand upright on the screwing hole 4a. Therefore, while driving in the small screw by hand or by a mechanism, the small screw 1 does not fall over, and the hole 4 is also not damaged. Furthermore, a plate 5 can reliably be fixed on the case 2 by the small screw 1.申请人：YAMAGATA KASHIO KK,CASIO COMPUT CO LTD更多信息请下载全文后查看。

专利名称：METHOD OF MANUFACTURING SCREW 发明人：KAMEDA Michihiro,INOUE Masaaki申请号：EP16887927.8申请日：20160128公开号：EP3257603B1公开日：20200115专利内容由知识产权出版社提供摘要：A method of machining a screw is provided that is capable of preventing formation of a protruding section at a thread tip section even when rolling is performed.A thread (2A) is formed by cutting on a cylindrical body inner circumferential surface (1a), and a surface of the thread (2A) is plastically deformed by rolling. Because of the cutting, a width (Lt) between both side surfaces (2ATs) of a thread tip section (2AT) is in a narrowed state as compared to a normal width (Lts) and is gradually narrowed toward a tip of the thread (2A) while a thread body section (2AM) has a width (Lm) between both side surfaces (2AMs) expanded as compared to a normal width (Lms) so that each of the side surfaces (2AMs) of the thread body section (2AM) is formed to bulge by an excess thickness portion (4) as compared to normal side surfaces (2AMss). The rolling plastically deforms the both side surfaces (2AMs) of the thread body section (2AM) to cause the excess thickness portion (4) to plastically flow toward each of the side surfaces (2ATs) of the thread tip section (2AT).代理机构：dompatent von Kreisler Selting Werner - Partnerschaft von Patent- und Rechtsanwälten mbB更多信息请下载全文后查看。

专利名称：Method for the manufacture of a stabilized filament superconductor having a highproportion of stabilization material发明人：Reinhard Both,Hans Hillmann,Walter Breuer 申请号：US06/941827申请日：19861215公开号：US04723355A公开日：19880209专利内容由知识产权出版社提供摘要：Superconductors having a high proportion of stabilization material are produced by first forming a composite member composed of pieces of stabilization material and rods of stabilization material containing cores of superconductive material and this composite member is deformed to reduce the cross section by extrusion and drawing. To increase the proportion of stabilization material, the composite material is subsequently introduced into an enveloping tube composed of stabilization material and the resulting assembly is deformed to final dimensions by means of further drawing processes. Breaks of the superconductive filaments are avoided by providing adequate amounts of stabilization material in the central region of the composite member. The result is that filament superconductors having a high proportion of stabilization material can be manufactured at a relatively low cost.申请人：VACUUMSCHMELZE GMBH代理机构：Hill, Van Santen, Steadman & Simpson更多信息请下载全文后查看。

Moreover, by detecting the position as the above method by paying attention to two points of the plural holes, the rotation angle of the object of tightening is determined by the rotation angle calculating means 6, and from this rotation angle, the deviation of other holes is calculated by the hole position correction calculating means 7.申请人：MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.更多信息请下载全文后查看。

专利名称：BONE SCREW AND METHOD FORPRODUCING THE THREADS THEREOF 发明人：Hansson, Henrik申请号：EP02712585.5申请日：20020220公开号：EP1367951B1公开日：20071114专利内容由知识产权出版社提供摘要：The present invention relates to a bone screw, a method for producing the threads of the bone screw and a drill for drilling holes therefor. The bone screw is adapted for implants for fixation of bone fragments at fractures and it comprises a threaded or tapped part (16) which is adapted to be screwed into a bone fragment at the fracture. The threaded part (16) extends backwards from a front end portion (17) of the bone screw (6) to an untapped part (18) thereof and has threads (19) with the same outer diameter (YD). The threads (19) have the same pitch of thread (P) and extend from a core (21). At least front parts of the core (21) closest to the front end portion (17) of the bone screw (6) are conical and have their least diameter (MD) situated at the front end portion (17). The threads (19) have truncated crests (23) and the width (b1-b7) of the crests (23) of the threads (19) increases in backwards direction from the front end portion (17). The width (B1-B6) of grooves (20) between the threads (19) decreases in dependence of the increase in width (b1-b7) of the crests (23).申请人：HANSSON HENRIK地址：SE国籍：SE代理机构：Wagner, Karl Heinz 更多信息请下载全文后查看。

专利名称：Screw-on acetabular prosthesis and methodof manufacturing the same发明人：HOERMANSDOERFER, GERD申请号：EP91250274.7申请日：19911008公开号：EP0480551A1公开日：19920415专利内容由知识产权出版社提供专利附图：摘要：The invention relates to a screw-in acetabular prosthesis (1) of sphericalgeometry with a special thread for cementless implantation, and to a method for itsmanufacture. The special thread follows in its pattern the spherical circumference formedby the nominal diameter of the cup (1) and is almost completely adapted in its base to this spherical circumference by virtue of the fact that the layout of the thread base is adapted to a very great extent to the spherical outer contour of the acetabular prosthesis (1) by means of strip-shaped part surfaces which are divided into steps in terms of angle and which extend parallel to one another and obliquely relative to the layout of the thread base. The special thread is cut according to the invention by machining with a number of tools, with different cutting edge angles in relation to the thread base (6, 7, 8), and on different paths. Compared to conventional spherical screw-in cups, the thread configuration according to the invention, by means of the freely available thread tooth depth, affords a substantially better primary fixation upon implantation and at the same time considerably reduces the risk of loosening by virtue of the fact that, as a result of the complete contact between the surface of the cup and the bone over a large area, only low specific forces act on the bone bed.申请人：HOERMANSDOERFER, GERD地址：KASTANIENECK 6 A; W-3167 BURGDORF-BEINHORN,Aspelohe 27a D-22848 Norderstedt DE国籍：DE代理机构：UEXKÜLL & STOLBERG更多信息请下载全文后查看。
