Abstract: A neck (3) of an electric guitar (1) comprises a first wooden neck member (31), and a second metal neck member (33). The second neck member (33) is disposed in a state in which strings (10) span from the nut (5) of the neck (3) to a bridge (8) of a body (2), and is partially secured in a plurality of locations to the first neck member (31) and the body (2). The strings (10) are in a state of tension between two ends of the second neck member (33), and good sound quality can be maintained because string vibrations are transmitted to the pickup side with good efficiency via the first neck member (31). Since the neck body portion (3A) protruding from the body (2) is reinforced by the second neck member (33), the incidence of warping or other forms of deformation in the neck body portion (3A) can be prevented.

Abstract: A brine recycling method where the used brine containing metal ions is added with a reaction agent to provide a agent-added brine. The reaction agent is of a kind which, when it is reacted with the metal ions, produces an insoluble substance, excluding an oxidant which, when reacted with oxygen, produces metal oxide. The agent-added brine is subsequently filtrated with the use of a microporous filtration membrane having an average pore size within the range of 0.005 to 1 .mu.m. A brine recycling apparatus is also disclosed which includes a filter module containing a microporous filtration membrane having an average pore size within the range of 0.005 to 1 .mu.m. The used brine is, after having been added with the reaction agent, supplied through a supply passage into the filter module. The filtrate is then removed from the filter module through a recovery passage.
