Title: Method for separating nitrogen compound from methyl naphthalene oil
Inventor: MOCHIDA ISAO
IPC: B01J20/02
Filed: 1989-10-31
Abstract: PURPOSE:To recover an N compound by bringing an N compound in a methylnaphthalene oil into contact with a burned matter of a metal salt having acidity in dried state and exhibiting neutrality in a state containing water to separate the N compound and treating metal salt thereof with water-organic solvent mixture. CONSTITUTION:A methylnaphthalene oil obtained by mainly distilling a coal tar or an oil consisting essentially of methylnaphthalene is brought into contact with a burned matter of a specific metal salt to separate an N compound. A metal salt, preferably a sulfate, most preferably nickel sulfate exhibiting acidity in dried state and exhibiting neutrality in a state containing water is used as the above-mentioned metal salt. The metal salt is burned in the air at 150-500 deg.C (preferably 300-400 deg.C) for 3-5hr for use. The N compound retained on burned matter of the metal salt is eliminated by bringing the N compound into contact with water to change the N compound from acidity to neutrality. Therefore, the N compound can be recovered by eluting the N compound treated with water using benzene, etc. The metal salt can be repeatedly used.

Title: Semiconductor device having contact resistance reducing layer
Inventor: SHIMOYAMA KENJI
IPC: H01L29/201
Filed: 1995-10-30
Abstract: PURPOSE: To reduce contact resistance, and remarkably reduce the operating voltage of a light emitting device, by forming a thin film GaPN layer between an AlGeInN based layer and an electrode. CONSTITUTION: In order to reduce contact resistance in wide band gap semiconductor, a thin film GaPxN1-x (0.1<=x<=0.9) layer whose band gap is very small or equal to zero is inserted. Thereby a potential barrier formed between an electrode and a surface layer is remarkably reduced, and ohmic contact is very easily obtained. The values of thickness, composition, etc., of the GaPxN1-x (0.1<=x<=0.9) layer between an AlGaInP based layer and the electrode are different from the carrier concentration and the composition (band gap) of a layer composed of AlGaInP based layer, and therefore not specially limited. Usually the desirable thickness is necessary only for satisfying the effect that the contact resistance is reduced.
