    摘要： A method for recovering platinum group elements comprises charging an oxide raw material entraining platinum group elements, copper oxide, solid carbonaceous reducing agent and flux into a closed electric furnace equipped with at least one electrode for heating material and a roof for substantially shielding material charged into the furnace from the exterior atmosphere. The charged material is melted and reduced to form a layer of molten metal under a molten slag layer and enrich platinum group elements in this molten metal. The oxide raw material, copper oxide, solid carbonaceous reducing agent and flux are prepared as powdery or particulate materials, premixed and then charged into the electric furnace. The heat-melted material in the furnace is allowed to stand at a temperature of 1200° to 1500° C. for at least 5 hours, with the molten metal containing platinum group elements then being discharged outside the furnace.

    摘要： A process of recovering a platinum group metal from a waste catalyst comprising a first step which comprises heating and melting the catalyst impregnated with the platinum group metal, copper and/or the oxide of copper, a flux component and a reductant component to form a layer containing the metal copper into which the platinum group metal is absorbed and another layer of the oxide, and then separating the metal copper; and a second step which comprises supplying air or oxygen as an oxidant to the separated metal copper for oxidizing under heating and melting to form a layer of partially oxidized metal copper and another layer of the metal copper containing the concentrated platinum group metal, and separating it. This process enables the economical recovery of the platinum group metal from the waste catalyst in a short period of time with high recovery rate.

    摘要： A tactile sensation providing apparatus, so as to reduce an influence by provision of a tactile sensation on detection of a position by a touch sensor, includes a touch sensor 11, a tactile sensation providing unit 12 disposed near the sensor 11 and configured to vibrate the sensor 11, a touch sensor control unit 20 configured to transmit a scanning signal to the sensor 11 and, by receiving the signal from the sensor 11, to detect the position of the contact to the sensor, signal lines 16, 18 configured to transmit the signal between the sensor 11 and the control unit 20, and a tactile sensation control unit 30 configured to, based on the position of the contact detected by the control unit 20, control the providing unit 12 to vibrate the sensor 11. The providing unit 12 is disposed avoiding overlapping with the lines 16, 18.
