摘要： A power-down delay unit 15 for delaying cutoff of a voltage is provided in the power supply line for supplying power to an optical module 14 of a transponder unit 16 of each wavelength. The power-down delay unit 15 assigns a different delay in power disconnection each wavelength. The length of the delay is a time required by an AMP unit or longer to change from an ALC mode to an AGC mode. With the configuration, when the power supply for supplying power to the plurality of transponder units 16 becomes faulty and output of a number of wavelengths simultaneously stops, the actual optical signal gradually stops output wavelength by one wavelength. Thereby a nonlinear effect because of going up of a power of an optical signal too much is not occurred, therefore it is able to prevent an undesired influence for a wavelength not to be stopped.
摘要翻译：在用于向每个波长的应答器单元16的光模块14供电的电源线中提供用于延迟电压截止的掉电延迟单元15。断电延迟单元15在每个波长的功率断开中分配不同的延迟。延迟的长度是AMP单元所需的时间或更长从ALC模式变为AGC模式的时间。通过该结构，当用于向多个应答器单元16供电的电源发生故障并且多个波长的输出同时停止时，实际的光信号逐渐将输出波长停止一个波长。因此，不会发生由于光信号的功率过大而引起的非线性效应，因此能够防止对不停止的波长的不期望的影响。

摘要： A power-down delay unit for delaying cutoff of a voltage is provided in a power supply line which supplies electrical power to an optical module of a transponder unit for each optical wavelength. The power-down delay unit assigns different delays for each wavelength. The length of the delay is a time required by an AMP unit to change from an ALC mode to an AGC mode or longer. When the power sources for supplying electrical power to the transponder units becomes faulty and outputs of several wavelengths are simultaneously going to stop, the power-down delay unit delays cutoff of the supply voltage to the optical modules by keeping supply voltage for a while to the optical modules on behalf of power sources enabling the optical modules to operate after the power sources shutdown, so that the actual optical signals gradually stop one by one.

摘要： In an image heating apparatus, outer peripheral surfaces of two endless belts are held in contact with each other to form a nip portion, and a recording material bearing a toner image is heated at the nip portion while being pinched and conveyed. In the image heating apparatus, the nip portion has a pre-nip portion formed by regions of the endless belts with no backup by pressure members, and a pressure nip portion where one endless belt with backup by the pressure members is held in contact with another endless belt. The image heating apparatus is capable of securing a large nip width compatible with an increase in speed and free from “pressure-absence” leading to image abnormality such as misregistration, thus enabling an image having a sufficient gloss to be obtained.
