An object of the present invention is to provide an embossed crepe paper which can clearly be formed into fine embossed shapes, and is excellent in the fluffy feel and therefore excellent in such as absorbency for fats. As a means of achieving this object, the method for manufacturing an embossed crepe paper, according to the present invention, is a method for manufacturing an embossed crepe paper comprising a step of embossing a raw crepe paper, wherein: a raw paper having a basis weight of 6 to 28 g/m2 is used as the raw crepe paper; and the embossing step includes the steps of: (a) supplying the raw crepe paper with water in an amount of 0.1 to 100 weight % based on the basis weight to thereby put the raw crepe paper in a wet condition; (b) embossing the wet-conditioned raw crepe paper; and (c) drying the embossed wet-conditioned raw crepe paper.

An optical transceiver 10 includes an optical device 16 which is provided upon a substrate 11, an optical connector 14 which is connected to an optical fiber 15a, and a connector holder 13 for optically connecting together the optical device and the optical connector 14. The connector holder 13 includes an engagement means 13c which holds the optical connector 14. The engagement means 13c holds the optical connector 14 when the optical connector 14 is pressed in towards the substrate. The optical connector 14 supports the optical fiber 15a so that the optical axis of the optical fiber 15a subtends a fixed angle with respect to the optical axis of the optical device 16. And the optical connector 14 includes a mirror 14g for optically connecting between the optical device 16 and the optical fiber 15a.
摘要:
An optical one-to-one protection switching apparatus exchanges signals between a transmit node and a receive node. If a fault is detected in the first transmission line (down-stream), a controller in the node controls a drive circuit so as to shut off a gate. Then, the controller in the transmit node upon receiving a switching request from the receive node, controls the drive circuit so as to shut off the gate. Thereby, the optical switch is switched. The transmitter of the client terminal is thus connected to the second transmission line (down-stream). Upon receiving the switching request from the transmit node, the optical switch in the receive node is switched. Thereby the receiver in the client terminal is connected to the second transmission line (down-stream).
