A wet method for treating a petroleum-originated combustion ash which comprises a step of preparing a combustion ash slurry, a metal oxidation step of preparing a slurry containing ammonium m-vanadate, a solid-liquid separation step of removing solids from a slurry containing ammonium m-vanadate, an ammonium sulfate double decomposition step of adding a magnesium compound to an ammonium sulfate solution recovered from the solid-liquid separation step and an ammonia recovery step of recovering ammonia from a double decomposition solution recovered from the double decomposition step, wherein the metal oxidation step is carried out at a reaction temperature of 50˚C or lower and at a concentration of ammonium sulfate in the solution of 20 to 45 wt %, and the solid-liquid separation step is carried out at a slurry temperature of 40˚C or lower by using a specific solid-liquid separation apparatus. The above wet treatment method is suitably used in particular when a relatively small amount of combustion ash is treated or when the combustion ash has a low content of carbon and a high content of vanadium, and thus is an industrially advantageous method which allows the recovery of vanadium with ease and with a simple process.

The present invention relates to a plectrum (1) having two portions (10, 12) being offset transversely but connected integrally by a stepped member (14). One portion (12) may have a tear-drop shaped playing edge (112), while the other portion may have a pointed edge (114) at one corner and another short pointed edge (118) at the second corner. A scallop playing edge (116) is typically joined to the short pointed edge (118). The stepped edge (14) is preferably in the shape of an arc. Other embodiments of the present invention include a plectrum (1a, 1b, 1c, 1d) having a planar body (20) with a tear-drop shaped playing edge (112a, 112b, 112c, 112d), a pointed playing edge (114a, 114b, 114c, 114d) and a short pointed edge (118a, 118b, 118c, 118d). A scallop shaped edge (116a, 116b, 116c, 116d) may be joined to the short playing edge (118). On the faces of the plectrum is preferably a ridge (201), a groove (202) or a combination of a ridge (201) and a groove (202) on the same or opposed face. The ridge or groove is optionally disposed across the centre of the plectrum and is in the form of an arc. The curved stepped edge (14) or the edges of the curved ridge (201) or groove (202) seek to provide a positive grip on the plectrum. The curved edges are also formed to fit comfortably with the curve of the user's thumb or finger.

A display comprising organic electroluminescence elements (10R, 10G, 10B) arranged on a driving substrate (11) in which a drive panel (10) for picking up light from the electroluminescence elements (10R, 10G, 10B) side can be pasted easily to a seal panel (20) provided with a color filter (22) on a sealing substrate (21). The drive panel (10) and the seal panel (20) are disposed oppositely and pasted entirely by an adhesive layer (30). The adhesive layer (30) is hardened at least thermally and hardening is started by coating with only one liquid or more than one liquid. A temporary fixing part (30A) is formed at the circumferential edge part of the adhesive layer (30). The temporary fixing part (30A) is composed of UV-curing resin, for example, and formed across the seal panel (20) and the drive panel (10) thus matching the relative position thereof.

An inductance device includes terminals (9) which are mounted to the inductance device from outside of a ring core (7). A fit-section (12) of one of each terminal (9) is bent along an outer wall (14), an upper face (15) of a groove (19), and an inner wall (13) of the ring core (7). A mount-section (11) of one of each terminal (9) extends from vicinity of an outer perimeter of the ring core (7) toward inside of a drum core (4) along a lower brim (3). When a shock is applied to the drum core (4) or the ring core (7), this structure prevents the drum core (4) and the ring core (7) from falling away from a board, where they have been mounted, leaving vicinity of the fit-section (12) of the terminal (9) on the board. This structure thus improves shock-proofness of the inductance device.
