摘要:
An optical device for rearranging wavelength channels in an optical network is disclosed. The optical device has a wavelength selective coupler having one input port and a plurality of output ports coupled to a plurality of input ports of an optical grating demultiplexor such as an arrayed waveguide grating. The wavelength channels in each of the input ports are dispersed by the demultiplexor and are directed to a plurality of output ports of the optical grating demultiplexor. As a result, at least one wavelength channel at each of the input ports of the optical grating demultiplexor is coupled into a common output port. The optical device is useful in passive optical networks wherein a same demultiplexor is used for simultaneous multiplexing and demultiplexing of wavelength channels.

Lock portions 4 are provided more inside than outermost wall surfaces 5a, 6a of a cassette relay block 1, and the cassette relay block 1 is inserted into space surrounded by peripheral walls 16 to 19 on an attaching side, and fixed by the lock portions 4 and locked portions 10 located on the peripheral wall side. The peripheral walls 16 to 19 on the attaching side are formed as a cassette frame 2. The cassette frame is used in common for the cassette relay block 1 or other cassette electric parts mounting blocks. The plural cassette frames are coupled to each other by lock members 54, and coupled to a connection box body by locked members thereby to constitute an electric connection box.

There is provided an information processing terminal that is provided with an IC chip that is capable of non-contact communication with a reader/writer. The information processing terminal includes a first storage portion, a second storage portion, and a data transfer portion. The first storage portion is provided within the IC chip and is capable of storing at least one type of data item that is used by the IC chip. The second storage portion is disposed outside the IC chip. The data transfer portion transfers the data item between the first storage portion and the second storage portion in accordance with a user input.

This invention provides a novel pigment, which is used, for example, in color image display devices and can form a blue pixel capable of providing a high level of bright saturation, particularly a refined pigment, which has bright hue and is excellent in pigment properties such as lightfastness, solvent resistance and heat resistance, and a process for producing the same, a pigment dispersion using the pigment, and an ink for a color filter. The novel pigment is a subphthalocyanine pigment that is prepared by converting subphthalocyanine represented by general formula (1), in which X represents a halogen atom, to a pigment, has diffraction peaks at least at diffraction angles (2θ) 7.0°, 12.3°, 20.4° and 23.4° in X-ray diffraction and an average particle diameter of 120 to 20 nm.
