    摘要: The present invention relates to a practical optical amplification module and the like realizing a wide-band gain spectrum with a small relative gain non-uniformity in L band. Pumping light from a pumping light source is supplied to a Bi type EDF by way of an optical coupler. Multiplexed signal light of L band inputted by way of an input end reaches the Bi type EDF by way of an optical coupler, an optical isolator, and an optical coupler, and is collectively amplified in the Bi type EDF. The multiplexed signal light amplified in the Bi type EDF is outputted from an output end by way of an optical coupler, an optical isolator, and an optical coupler.

    摘要: The present invention relates to an optical fiber transmission line and the like comprising a structure for enabling repeating sections to become further longer. The optical fiber transmission line comprises first and second optical fibers successively disposed along the advancing direction of signal light, and an optical multiplexer for supplying Raman amplification pumping light to one of the first and second optical fibers. The first and second optical fibers are fusion-spliced to each other, whereas at least one of them has a core region substantially made of pure silica glass. The second optical fiber has an effective area smaller than that of the first optical fiber, and a chromatic dispersion and a length which are different from those of the first optical fiber. In particular, the respective lengths of the first and second optical fibers are appropriately regulated so as to effectively suppress nonlinear phenomena other than Raman amplification.

    摘要: A high-voltage variable resistor includes a circuit section contained in an insulating casing, a snap-in terminal inserted in a terminal base portion of the casing and connected to an output portion of the circuit section, and an output connecting electrode inserted in the terminal base portion from a direction orthogonal to the snap-in terminal and press-fitted in and connected to the snap-in terminal. The terminal base portion of the casing has an insertion groove for guiding and inserting the snap-in terminal, an insertion hole for guiding and inserting the output connecting electrode, and a relief groove formed on a side face of the insertion groove intersecting the insertion hole. The insertion groove, the insertion hole, and the relief groove are simultaneously formed by a metal mold of the structure to be pierced.

    摘要: To output sounds generated by multiple objects disposed in a virtual space in as easy a manner as possible while giving live feelings, a storage unit (202) of a game machine (201) stores information on objects of a first type and a second type which move in the virtual space. A basic sound acquiring unit (203) acquires basic sound information corresponding to the total number of the objects. An imitation sound acquiring unit (204) acquires imitation sound information imitating a sound generated by an object of the first type from its position in the virtual space. A mixing output unit (205) mixes and outputs the basic sound information and the imitation sound information. An input receiving unit (206) receives an instruction input from the user. In a case where the instruction input satisfies a predetermined extinction condition, a deleting unit (207) deletes any of objects of the first type from the storage unit (202) if there is no object of the second type stored in the storage unit (202), and deletes any of objects of the second type from the storage unit (202) if there is.
