  • Patent number: 10373764
    Abstract: A method for producing agglomerated tantalum particles, comprising: a step for grinding secondary tantalum particles, which are obtained by reducing a tantalum salt, and adding water thereto to give a water-containing mass; a step for drying said water-containing mass to give a dry mass; a step for sieving said dry mass to give spherical particles; and a step for heating said spherical particles. A mixed tantalum powder comprising a mixture of agglomerated tantalum particles (X) with agglomerated tantalum particles (Y), wherein said agglomerated tantalum particles (X) show a cumulative percentage of particles with particle size of 3 ?m or less of 5 mass % or less after 25 W ultrasonic radiation for 10 min, while said agglomerated tantalum particles (Y) show a cumulative percentage of particles with particle size of 3 ?m or less of 10 mass % or more after 25 W ultrasonic radiation for 10 min.

  • Patent number: 7079048
    Abstract: A mobile communications terminal receives information based on a location and time at regular time intervals. To acquire information, an input section accepts setting input from the user and stores the setting in a specified information storage section. An acquisition request control section sends an instruction to a practical information acquisition section at regular time intervals, and the practical information acquisition section acquires the user's desired information from an external server based on the instruction. A display section displays the acquired information according to a predetermined display mode.

  • Publication number: 20060016291
    Abstract: A niobium powder can be used to manufacture a niobium capacitor of excellent electrical properties The niobium powder when formed into a sintered body of 3.15 to 3.9 g/cm3 density exhibits a capacitance (CV value at a formation voltage of 20V) ranging from 80 to 240 kCV/g and a CV retention of 57% or higher. With respect to the production of the niobium powder, the employed potassium niobate fluoride has a water content of 1000 ppm or less as determined from the amount of water generated upon heating at 600° C. according to the Karl Fischer method.
