Title: Unused indication method of embedded pipe
Inventor: KAMEI MINORU
IPC: F16L1/00
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To provide the indication method of unused pipe which can discriminate whether the pipe exposed from the earth is a used pipe or unused pipe easily. SOLUTION: In a first process, a hole s1 or slit for communicating the outside/inside of a laid pipe P is formed to the arbitrary position of the wall of the pipe P by entering an inner surface cutter device from the opened end Pa side in the embedded pipe P and in a second process, a filler R is filled by applying a pressure into the pipe P in which the hole s1 or slit are formed on the pipe wall in the first process. A lump for indicating the unused pipe is formed by the filler R projected from the hole s1 or slit s2 to the outside of the wall of the pipe P.

Title: Method for measuring intermediate mixed layer of multilayer resist
Inventor: UEDA YUTAKA
IPC: H01L21/027
Filed: 1987-09-21
Abstract: PURPOSE:To accurately measure the thickness of an intermediate mixed layer, by reducing the dripping amount of an upper layer material when said material is applied to form a non-coating part. CONSTITUTION:A lower layer resist 2 is applied to a wafer 1 and an upper layer resist material 4 for measuring the intermediate mixed layer 3 with the lower layer resist 2 is applied to said resist 2 to form an upper layer non-coating part 5 on the wafer 1. In this case, when the dripping amount of the upper layer resist material 4 is reduced when said material applied as shown by a drawing (a), the non-coating part 5 is formed to the end of the wafer 1 as shown by a drawing (b). Next, when the upper layer material 4 (thickness, 0.5-1.0mum) is entirely removed, the difference in level of the intermediate mixed layer 3 (thickness; 0.1-0.2mum) is formed on the lower layer resist 2 (thickness; 1.0-1.5mum) as shown by a drawing (c) and, by measuring said difference in level, the thickness of the intermediate mixed layer 3 is measured. Therefore, since the non-coating part is formed by reducing the dripping amount of the upper layer material at the coating time thereof and the difference in level of the intermediate mixed layer formed on the lower layer resist can be utilized after the removal of the whole of the upper layer material, the thickness of said intermediate mixed layer can be accurately measured.
