Title: Reflected wave absorbing device of omnidirctional irregular wave generating facility
Inventor: IKETANI TAKESHI
IPC: G01M10/00
Filed: 1992-06-29
Abstract: PURPOSE:To absorb reflected waves in many directions in an omnidirectional irregular wave generating facility. CONSTITUTION:The reflected wave incident to the j'th one of individually driven wave generating boards 3 in N pieces is determined by a subtracting means 32 as the difference deltaj (=muj-tauj) between the target water level variation (tauj) to be set for the board in order to generate irregular waves and the observed water level variation (muj) given by a wave height meter 7 on the wave generation surface of the board 3. The velocity muj of reflected wave absorbing motions which the j'th board 3 should make for absorbing reflected waves is calculated by a control means 36 from the difference deltaj corresponding to the reflected wave at the board 3 and the difference deltaj-1 or deltaj+1 corresponding to the reflected wave at least at the adjoining board on one side of the applicable board 3, and the reflected wave absorbing motions are made by this control means 36. For determining the reflective absorbing motion velocity uj of each board 3, it may be accepted that all differences deltaj of boards 3 in N pieces are used or that the difference deltaj of the board 3 and differences deltaj-1 and deltaj+1 of the adjoining boards on both sides are used.

The head part of the solder film 5a is exposed on an interlayer insulating film 6. Only the head part is fused by heat treatment and a spherical shape is obtained. Thus a bump is formed. Even if the pitch between the neighboring bumps is small, short-circuit between them can be prevented.
