Abstract: PROBLEM TO BE SOLVED: To precisely execute gain fixing control by making a value, which is shown by a specific formula including a constant value corresponding to a naturally emitted light (ASE) power a light amplifier part generates at the time of operating, the detection gain of the light amplifier part. SOLUTION: An optical detector 3-1 detects an input signal optical power Pin and an optical detector 3-2 detects an output signal optical power Pout. The light amplifier 1A is provided with a rare earth added fiber 11 and an exciting light source 12 executing front excitation. A gain detecting part 4A inputs the input signal optical power Pin, the output signal optical power Pout and an ASE power PASE to make (Pout-PASE)/Pin a gain A.

Abstract: PURPOSE:To improve fertilization effect by adding an additive composed mainly of CaO and capable of reacting with lower fatty acids in a perishable waste and producing fatty acid calcium salts to the perishable waste composed of a solid-liquid mixture. CONSTITUTION:Water is added to a perishable waste such as cattle excretions, an excessive sludge of service water or sewerage or SHOCHU (distilled alcoholic beverage made from rice or sweet potato) less to prepare a slurried mixture having 75-97wt.% water content. With 100 pts.wt. resultant perishable waste slurry, 5-25 pts.wt. porous additive containing CaO as the main component, Ca(OH)2, CaCO3 and other substances is admixed and the obtained mixture is reacted with stirring for a prescribed hour. The above-mentioned additive reacts with lower fatty acids such as formic acid and acetic acid, organic phosphates, phospholipids and higher fatty acids respectively contained in the perishable waste to form respective complex salts. Sparingly soluble calcium salts are produced thereby and a composite material containing inorganic substances suitably involved in organic substances is obtained. The resultant composite material is then dried, thus giving the objective soil conditioner excellent in fertilization effect.
