Title: Heating treatment method of constricted part of blood vessel and local heating type catheter therefor
Inventor: MOORISU BUTSUHIBINDAA
IPC: A61M29/00
Filed: 1994-04-25
Abstract: PURPOSE:To prevent reconstriction after the constricted part of a blood vessel is expanded. CONSTITUTION:The front end of a catheter body 1 is radially provided with plural wires 4 for electrodes. These wires 4 for the electrodes are bent outward approximately to a V shape and the sharp electrodes 2 for high-frequency heating are formed in the curved parts. Central wires 6 are inserted into the centers of the wires 4 for the electrodes and the front ends of the wires 4 for the electrodes are respectively fixed to the front ends of the central wires 6. The electrodes 2 are inserted into the deep part of the inside wall of the vessel when the wires 4 for electrodes are moved forward in the state of fixing the pisitions of central wires 6. The parts near the electrodes 2 are heated by high- frequency heating to locally fuse the inside walls of the blood vessel to the ambient tissues. The range of a burn is smaller than the range of the burn by the conventional method even if the build-up of the tissues is generated by the burn in a part of the blood vessel. The constriction is thus minimized.

Title: Electronic component, manufacture of electronic component and mounting method thereof
Inventor: YAMAZAKI OSAMU
IPC: H01L21/60
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To obtain stable mounting quality even in high density mounting by providing a connecting means consisting of a material containing a metallic element forming a soft soldering material or soft solder and a solid soluble body for connecting a plurality of terminals mutually. SOLUTION: An electronic component body 7 is comprised of a material containing a metallic element forming a soft soldering material or soft solder and a solid soluble body. End parts of a plurality of terminals 8 of the electronic component body 7 are connected by a strip solder sheet 9 as a connecting means. The soft solder sheet 9 is thereby stuck in the terminal 8 and is readily compressed. The solder sheet 9 dissolves and the part between terminals 8 is separated by surface tension during the dissolving and concentrates on the part of the terminal 8. The electronic component body 7 is subjected to surface mounting by solder 9a. Since the terminals are connected mechanically by the strip solder sheet 9 in this way, mechanical strength of the terminal 8 increases and stable mounting becomes possible.

Holes formed in the N<-> type layer 2 are deeper than an N-type source region formed in the upper part of the N<-> type layer 2. After the photoresist is removed, oxide films 4 are formed on the inside walls and bottoms of the holes and the oxide films formed on the bottoms of the holes are removed. Doped polycrystalline Si 5 is deposited over the whole surface and the polycrystalline Si 5 on the oxide film 3 is removed. The polycrystalline Si 5 in the holes is also etched and removed until the surface of the Si 5 comes to the same level as the surface of the N<-> type layer 2. Ions are implanted in the part of the N<-> type layer 2 where a control gate region is to be formed utilizing the photoresist PR as a mask. After annealing, a P-type shielded gate region 6 and a P-type control gate region 7 are formed.
