Abstract: A loudspeaker includes a diaphragm body having a dome shape protruding upwardly, a magnetic circuit disposed below the diaphragm body, a voice coil coupled to the diaphragm body, an edge coupled to an outer circumference of the diaphragm body, and a frame coupled to the edge. The edge includes a first coupling portion provided at an outer circumference of the edge, a second coupling portion provided at an inner circumference of the edge and coupled to an outer circumference of the diaphragm body, and a roll portion disposed between the first coupling portion and the second coupling portion. The edge has a surface facing downward. The frame has a connecting surface disposed below the second coupling portion and coupled to the surface of the edge at the first coupling portion of the edge. This loudspeaker can decrease distortion of sound.

Abstract: Provided is an antibody production method whereby it is possible to repeatedly acquire antibodies produced by fish without killing the fish. Specifically provided is an antibody production method whereby it is possible to repeatedly acquire the antibodies produced by a fish, without killing the fish, by administering antigens to fish that have blisters.

Abstract: Between one course and the other course adjacent to each other, an amount of elastic yarns for the other course is set smaller than that for the one course so that the elastic yarn knitted into the other course is stretched by a resilience of the elastic yarn knitted into the one course contracting from a stretched state when being knitted. When making a power-enhanced knit fabric, elastic yarns are knitted under tension, so as to generate a difference in amounts of stretch of the elastic yarns during knitting, thereby producing a difference between repulsive forces of the elastic yarns for each pair of adjacent courses.

Abstract: A speaker of the present invention includes the following: a diaphragm that includes an inner periphery coupled to a voice coil, and a corrugation provided at the intermediate position between the inner periphery and an outer periphery; a speaker edge for supporting the outer periphery of the diaphragm; and a damping member attached to an outer peripheral part of the diaphragm outside the vicinity of an outer periphery of the corrugation. The effective vibration area of an inner peripheral part of the diaphragm inside an inner periphery of the corrugation is substantially half or less of the total effective vibration area. The damping member is configured as a damping portion by extending an overlap portion of the speaker edge overlapping with the diaphragm to the vicinity of the outer periphery of the corrugation.

Abstract: The present invention relates to the production of an N36-binding peptide at low cost and in a large quantity utilizing a microorganism. More specifically, the present invention relates to a method for producing an N36-binding peptide comprising introducing a recombinant vector into which a DNA molecule encoding an N36-binding peptide that binds to an N36 protein derived from a retrovirus that causes immunodeficiency in a mammal has been incorporated into E. coli as a host to produce a transformant.
