摘要:
The present invention is related to an isolated chemolithotrophic bacterial strain belonging to the specie Acidithiobacillus ferrooxidans, named “Wenelen” and deposited at the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH—DSMZ under classification number DSM 16786, the use of said bacteria for leaching ores or concentrates containing of metallic sulfide species and leaching processes based on the use of said bacteria or mixtures that contain said bacteria. This Wenelen DSM 16786 strain has an increased oxidizing activity, especially regarding chalcopyrite, when compared to known bacteria. Due to the former feature, this bacteria strain show great interest for biomining applications and it is presently being subjected to annotation processes after sequencing.

A light signal switching apparatus has an input port and output ports, and outputs an output light from a desired output port. The apparatus has a splitter polarizing an input light into first and second polarized light whose polarization planes are different mutually by 90 degrees, a first polarization controller rotating a polarization plane of the second polarized light by 90 degrees to output a third polarized light, a first optical switch switching a path of the first polarized light to the desired output port side, a second optical switch switching a path of the third polarized light to the desired output port side, a second polarization controller rotating a polarization plane of the first polarized light by 90 degrees to output a fourth polarized light, and a combiner combining the third polarized light with the fourth polarized light, to output a combined light to the desired output port.

An electric comic book delivering server delivers translated electric comic book by transmitting original electric comic book data, mask data and translation data to a client terminal via a communication network. The mask data is used to mask a display portion of first language. The translation data is used to superimpose a display portion of second language on the masked display portion of first language. When the electric comic book delivering server obtains mask data and translation data from another client terminal in which the mask data and the translation data have been created, the electric comic book delivering server registers the mask data and the translation data into a database thereof.

There is provided a content data reproducing system that allows, in a user terminal adapted to be able to read a recording medium storing a content data encrypted with a predetermined encrypted key data, the content data to be reproduced after a CM data is reproduced. The system includes a CM data transmission portion that transmits the CM data to the user terminal in response to a request from the user terminal. When the sensing portion senses that the reproducing of the CM data has been completed in the user terminal, a permission portion permits the user terminal to use the encrypted key data to decrypt and reproducing the content data.
摘要:
An optical packet network system of a ring type, capable of preventing degradation of an optical signal, can be implemented by providing a mechanism relatively simple in structure, capable of erasing light noise if the optical packet signal does not exists. In the optical packet network system made up by interconnecting respective nodes adjacent to each other, and connecting a sending source of an optical packet signal to a ring, a light noise removal function block is provided between the respective nodes adjacent to each other.

A matrix optical switch that can switch the transmission path of an optical signal without requiring a driving unit for each optical switch is realized. A matrix optical switch for switching a transmission path of an optical signal by connecting plural input sides and plural output sides, respectively, comprises: a semiconductor optical waveguide substrate; a photo mask choosing system for selecting and arranging one photo mask from plural photo masks each of which has printed thereon a pattern connecting plural input sides to plural output sides; and a light source for casting output light having larger energy than a band gap of the semiconductor optical waveguide substrate onto a photon injection area between the plural input sides and the plural output sides on the semiconductor optical waveguide substrate via the selected photo mask.
摘要:
An optical switch has an input port, output ports, optical waveguides whose output path of an optical signal branch into two. A first stage optical switch section is provided in a branching portion of the optical waveguide, which switches a propagating path of an optical signal to a path leading to the desired output port. A subsequent stage optical switch section is provided in a branching portion of the optical waveguide subsequent to the first stage optical switch section, which switches a propagating path of a leakage light, which is leaked from the first stage optical switch section, to a path which does not propagates the leakage light to any of the output ports. The first stage optical switch section and the subsequent stage optical switch section switch a path of an optical signal according to a refractive index change caused by a carrier injection.

The present invention makes improvements in a mobile communication system that performs a communication via a communication network provided in a mobile body to execute a data transfer. The present system comprises a plurality of nodes, a path control device which receives data from the nodes respectively, selects a path for the data transfer on the communication network, and outputs the data, first optical fibers which connect each of the nodes and the path control device and transfer the data, and second optical fibers provided in parallel with the first optical fibers. In the present system, the path control device communicates with the node via the second optical fiber when a failure occurs in the first optical fiber.
