The present invention relates to a joint () that includes a first member () to be jointed, a second member () to be jointed and a jointing layer () located between the first member () and the second member (). The jointing layer () is made of Sn metal and a metallic material with a melting point higher than the melting point of the Sn metal. The present invention relates also to a method of joining this first member () to the second member ().

Joint with first and second members with a joining layer located therebetween containing Sn metal and another metallic material; methods for forming the same joint

The present invention provides a water purification material capable of selectively adsorbing phosphorus dissolved in wastewater, and also provides a water purification method employing the material. The water purification material comprises a composite metal hydroxide containing iron ions and calcium ions in its structure, and this composite metal hydroxide has a layered structure. In the water purification method of the present invention, the water purification material is brought into contact with wastewater so as to remove and recover phosphate ions in the wastewater.

Water purification material

A phosphorus recovery method and a phosphorus recovery system which can make equipment size small, and can be added easily also to an existing wastewater treatment facility, and can recover phosphorus by low cost, are provided. A phosphorus compound adsorption material includes a nitrogen containing compound which has an amino group at an end of molecular structure, a carrier supporting the nitrogen containing compound, and zinc ion or iron ion fixed to the nitrogen containing compound. After passing water to be treated containing phosphorus to an adsorption tower filled up with this phosphorus compound adsorption material to make phosphorus stick to the phosphorus compound adsorption material, a drug solution for desorption is supplied to the adsorption tower, and phosphorus is desorbed in liquid and is recovered.

An electrode material includes an alloy having a GdNiSntype crystal structure.

Electrode material, method of manufacturing the electrode material, electrode, and nonaqueous electrolyte battery

A process for producing a light-emitting semiconductor device includes: (i) mixing at least one low-molecular silane or at least one silanol with an alcohol solution containing an alkoxysiloxane to prepare a mixture solution, the amount of the silane or silanol being from 10% by weight to 50% by weight based on the dry weight of an encapsulating material to be formed; (ii) applying the mixture solution to a light-emitting element; (iii) vaporizing the alcohol solvent in the mixture solution applied and drying the residual mixture to thereby form the encapsulating material; and (iv) curing the encapsulating material.

Process for producing light-emitting semiconductor device

A nonaqueous electrolyte battery includes a positive electrode, a negative electrode and a nonaqueous electrolyte. The negative electrode contains an intermetallic compound having an LaCoSntype crystal structure of which alkaline-earth metal atoms occupy La sites. The nonaqueous electrolyte contains at least one of methyl ethyl carbonate and dimethyl carbonate.
