Abstract: PURPOSE:To completely eliminate connection failure between a conducting viahole and a surface pattern, by forming supplement conductor having the same thickness as a thin resin film in a small exposed hole, eliminating the resin film around the supplement conductor to form a minute cylindrical space, and attaching and growing conducting metal on the exposed part of the supplement conductor by electroplating. CONSTITUTION:Supplement conductor having the same thickness as a thin resin film 3 is formed in an small exposed hole 14a of the thin resin film 3 formed on the surface of an insulating substratum 1. A cylindrical space having a size nearly equal to the conducting viahole 2 is formed around the supplement conductor 16 by eliminating the thin resin film 3 around the supplement conductor. By electroplating using the conducting viahole 2 in the insulating substratum 1 as an electrode, conducting metal is attached to the space and the supplement metal 16 is grown. As a result, the supplement conductor 16 grows in a drum type, and tightly sticks to the end surface of the conducting viahole 2, so that the connection between a conducting thin film 5 formed on the surface of the thin resin film 3 by sputtering and the supplement conductor 16 becomes also strong. Thereby the connection failure between the conducting viahole 2 and a surface pattern can completely be eliminated.

Title: Inflatable lifeboat
Inventor: SUGIMOTO ATSUO
IPC: B63B7/08
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To reduce labor when a sufferer rides a lifeboat so as to greatly facilitate riding by composing a riding base gas room by joining the same with a main gas room such that when external pressure is applied, the internal filling gas of the riding gas room is moved to the main gas room side so as to cause a change in a capacity. SOLUTION: A main gas room 10 and a riding base gas room 30 are filled with gas such as carbon dioxide and the riding base gas room 30 is connected to the main gas room 10 such that when external pressure is applied to the riding base gas room 30 while a sufferer tries to ride a lifeboat 1 the gas filling the inside of the riding base gas room 30 is moved to cause a change in capacity. Thus, when the sufferer rides the lifeboat 1, the riding base gas room 30 protruded from the main gas room 10 is easily bent into the water perpendicularly from the vicinity of the joint with the main gas room 10 and then ride the lifeboat main body by placing the foot in a step positioned in the bent tip. Thus, a riding operation is greatly facilitated.
