Title: Method for improving drilling depth measurements
Inventor: HUTCHINSON MARK W
IPC: E21B47/04
Filed: 2003-04-03
Abstract: A method for determining a depth of a wellbore is disclosed. The method includes determining change in a suspended weight of a drill string from a first time to a second time. A change in axial position of the upper portion of the drill string between the first time and the second time is determined.  An expected amount of drill string compression related to the change in suspended weight is corrected for movement of a lower portion of the drill string between the first time and the second time. A position of the lower portion of the drill string is calculated from the change in axial position and the corrected amount of drill string compression. In one embodiment, the correcting includes estimating drill bit movement by determining an axial motion of the drill string at the earth's surface between two times having a same suspended weight of the drill string.

Title: Biodegradable/absorbable adhesive medical material
Inventor: TAGUCHI TETSUSHI
IPC: A61L31/00
Filed: 2004-02-05
Abstract: It has been required to develop a tissue adhesive for biological use which has a strong adhesive force and a low biological toxicity. To occlude a blood vessel, stop bleeding, stop air leakage or blocking aneurysm, the existing hemostatic materials, vascular occluding materials, sealants and aneurysm blocking agents would frequently peel off from the application site and thus there is no such a product having a satisfactory hemostatic effect or blocking strength. Thus, it is intended to provide a two-component system biodegradable and pressure-sensitive material for medical use which contains a biodegradable polymer as the adhesive component together with a low-molecular weight derivative, wherein a carboxyl group in a di- or tricarboxlyic acid occurring in the citric acid cycle is modified with an electron-drawing group (succinimidyl, sulfosuccinimidyl, maleimidyl, phthalimidyl, imidazolyl, nitrophenyl, tresyl or a combination of two or more of these derivatives), as a hardening component.
