Title: Medical needle and its production
Inventor: KAWANO TAKUMI
IPC: A61M5/158
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To make a medical needle usable with safety without giving paint to a patient as sharp cutting quality may be assured to a blade surface by arranging a weld zone of a needle tube at the rear end of the blade surface without arranging the weld zone at the front end of the blade surface. SOLUTION: The medical needle 1 is formed by arranging the weld zone 6 of the needle tube 2 at the rear end 5 of the blade surface 3 without arranging the same at the front end 4 of the blade surface 3. The weld zone 6 may be slightly interior in strength in comparison with the other non-weld zones but occupies just the extremely small area of the blade surface 3 as the weld zone is arranged at the rear end 5 of the blade surface 3 which least affects the cutting quality of the blade surface 3. On the other hand, the other non-weld zones exclusive of the weld zone 6 at one point of the blade surface 3 maintain the stable and uniform strength. Then, the uniform polishing of the non-weld zones exclusive of the front end and the weld zone 6 mostly governing the cutting quality is made possible at the time of polishing the blade surface 3.  Although the weld zone 6 of the one point may entail some distortion, the distortion does not affect the cutting quality of the blade surface 3.

Abstract: PURPOSE:To minimize reduction in the wave transmitting/receiving sensitivity product by providing a phase shifting circuit on an active sonar circuit for an acoustic homing apparatus to control the main axis of a wave beam received so that it coincides the direction of receiving waves according to the turning of an underwater navigating body. CONSTITUTION:The curve C indicating the wave transmitting/receiving sensitivity product DI varies with the turning. When the wave transmitting directivity (curve A) coincides with the wave receiving directivity (curve B), the reduction in the wave transmitting/receiving sensitivity product is minimized and increases before and after the point of coincidence. The axis of the wave receiving directivity is controlled to coincide the axis of the wave transmitting directivity regardless of the turning of an underwater navigating body. This maintains reduction in the wave transmitting/receiving sensitivity product at the minimum in the turning.
