Title: Underwater towing object
Inventor: UCHIDA HIROSHI
IPC: B63C11/00
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To restrain unstable motion even during high speed towing, by providing back end configuration of an underwater towing object which is towed underwater by a cable with a plane substantially vertical in the towing direction, and by connecting string whose resistance is combined with the back end in the towing direction with the back end of the towing object. SOLUTION: The ratio of length to diameter of an underwater towing object 1 is 7:1. The underwater towing object 1 is connected with a cable 2 at its front end and is towed. Ratio of diameter of the underwater towing object 1 to that of the cable 2 is 6:1. A body 3 is cylindrical, the front end 4 is conical, and a back end 5 has a shape formed by cutting vertically to a cylindrical shaft. A center of gravity G and a center of float B are on a center of the cylindrical shaft, and the center of gravity G is positioned forward of the center of float B in the towing direction. This structure allows stable towing with a simple configuration and even at high speed. When a string is attached to the back end to increase stability, providing a resistance for an back end of the string can shorten the string, and placing the center of gravity G forward of the center of float B in the towing direction stabilizes the towing object.

Abstract: PURPOSE:To ensure peeling strength positively, to realize cost reduction through reduction in time for pattern design and reduction of a chip size and to improve quality by removing an insulating film partially or entirely in a bonding pad part and by realizing direct contact between a wiring layer and a substrate. CONSTITUTION:An insulating film removal part 4 is provided by removing a part of an insulating film 3 in the process of process treatment to acquire a path for connecting a substrate 2 and a wiring layer 1 of a pad part. Since the insulating film removal part 4 is provided to the insulating film 3 in this way, irregularities are formed in a part wherein the wiring layer 1 of the pad part is formed and it is possible to ensure a contact area larger than that when the wiring layer 1 of the pad part is formed on a flat insulating film 3, thereby improving peeling strength. Meanwhile, a plurality of pads and the substrate 2 are naturally connected in the process, shortcircuit is generated between pads and it becomes impossible to ensure signal and electric potential of each pad. The phenomenon can be avoided only by carrying out electical separation of a substrate region connected to a pad below each pad. For example, it is realized readily by forming a reverse direction structure of a diode.

Filed: 1989-07-26
Abstract: PURPOSE:To manufacture a printed board with a high reliability through hole by forming a surface treatment layer which is apt to generate copper ions during electrodeposition before forming a photosensitive film and forming a perfect etching resist film in a short time. CONSTITUTION:A substrate P having a copper layer 3 is immersed in a solution of NaOH/NaClO3 as a pretreatment, thereby forming a surface treatment layer 5 which comprises copper oxide.

During the electrodeposition, the copper oxide of the treated layer 5 turns into copper ions by electrolysis. Then, it is subjected to complex reaction with a carboxyl group of the photosensitive film 4 formed by electrocoating, thereby forming an insoluble complex resist film 6. The substrate P is exposed to ultraviolet rays, using a printing film, and developed with an Na2CO3 solution, thereby forming an etching resist film. Then, it is etched with a copper chloride etching solution, thereby melting and eliminating the copper layer 3 except for a required pattern, and removing the photosensitive film 4 with NaOH solution and forming the specified pattern.
