摘要： A dual structure for a multiplexing section extended to an OSU is obtained without adding a dynamic function, such as an optical switch, to a W-MULDEM. The W-MULDEM of an optical wavelength division multiplexing access system divides, among ports corresponding to the individual ONUs, downstream optical signals having wavelengths λd1 to λdn, which are received along a current-use optical fiber, or downstream optical signals having wavelengths λd1+Δλ to λdn+Δλ, which are received along a redundant optical fiber. The W-MULDEM also multiplexes, for the port that corresponds to the current-use optical fiber or the redundant optical fiber, upstream optical signals having wavelengths λu1 to λun or wavelengths λu1+Δλ to λun+Δλ, which are received along optical fibers corresponding to the ONUs. A wavelength difference between the downstream optical signal and the upstream optical signal that are consonant with each ONU is defined as an integer times the FSR of an AWG.

摘要： A brake control device to be used for brake control and traction control of a motor vehicle includes a shuttle valve, a modulator, a traction control valve and a throttle valve. The shuttle valve selects a higher air pressure either from a brake valve, which operates when the brake is applied, or from a traction control valve, which opens during traction control to prevent wheel slippage. The shuttle valve allows the higher of the two air pressures to enter the modulator, which converts the entering air pressure to a brake hydraulic pressure to be supplied to the wheel cylinders of the motor vehicle. The throttle valve provided between the traction control valve and the shuttle valve decreases the air pressure from the traction control valve to be transmitted to the modulator when the traction control is activated. The throttle valve and the shuttle valve cooperate to increase the number of discharge air passages so that the brake control device has a greater discharge capacity when the brakes are released.

摘要翻译： 用于机动车辆的制动控制和牵引力控制的制动控制装置包括梭阀，调节器，牵引控制阀和节流阀。 梭阀选择来自在施加制动器时操作的制动阀或来自在牵引力控制期间打开以防止车轮打滑的牵引控制阀的较高气压。 梭阀允许两个空气压力中的较高者进入调节器，其将进入的空气压力转换成制动液压，以供应到机动车辆的轮缸。 设置在牵引控制阀和梭阀之间的节流阀在牵引控制被启动时减小来自牵引控制阀的空气压力，以传递到调制器。 节流阀和梭阀配合以增加排放空气通道的数量，使得制动控制装置在制动器被释放时具有更大的放电容量。

摘要： In a brake control device with a traction control function, there is provided a traction control valve for connecting a first conduit extending from a first pressure source to a brake valve to a second conduit extending from a second pressure source for arbitrarily switching the route of the pressure of air supplied from the traction valve to the modulator. With this construction, it is possible to obtain the compact brake control device capable of reducing the number of parts and enhancing the brake responsiveness with a low cost.
