    摘要： Voice coil body of a loudspeaker is provided at the outer circumferential wall surface with a supporting section. Diameter of the inner circumference of suspension holder is greater than outer diameter of the voice coil body while diameter of the inner circumference of diaphragm is greater than diameter of the inner circumference of suspension holder for facilitating a gluing of the inner circumferential end of suspension holder and the inner circumferential end of diaphragm on the supporting section and to the voice coil body. By so doing, harmonic distortion of a loudspeaker can be further reduced.

    摘要： An image-forming apparatus is provided with: a photoconductor drum having a surface on which a toner image is formed, a transfer drum for transferring the toner image onto a copying material by allowing the copying material to contact the photoconductor drum, and a ground roller for electrostatically attracting the copying material onto the transfer drum prior to transferring the toner image onto the copying material. He transfer drum is constituted by a semi-conductive layer and a dielectric layer that are stacked on a conductive layer. [Supposing that] The nip width between the photoconductor drum and the transfer drum is L1, the rotation speed of the two drums is Vp, and the time constant, which is represented by a product of the resistance and the capacitance between the two drums, is .tau., the relationship represented by L1/Vp
