摘要： To permit releasing an excessive rod pressure from a first hydraulic cylinder and also effectively using pressure oil of its rod chamber upon performing such an operation that pressure oil is fed to a bottom chamber of a second hydraulic cylinder, a hydraulic drive unit is provided with a boom cylinder, an arm cylinder, a communication line communicating a rod chamber of the boom cylinder and a bottom chamber of the arm cylinder with each other, and a switching valve arranged on the communication line for communicating or shutting off the communication line in accordance with a rod pressure of the boom cylinder. When an arm-crowding single operation is performed and by its digging counterforce, a rod pressure of the boom cylinder rises to a high pressure of at least a predetermined pressure, the switching valve is changed over from a shut-off position to a communicating position to feed pressure oil from the rod chamber of the boom cylinder to the bottom chamber of the arm cylinder. The boom cylinder is hence caused to automatically extend, thereby avoiding lifting of a body of a hydraulic excavator.

摘要： An optical amplification system capable of operating without being affected by the waveform of the incoming optical signal is provided for amplifying the optical signal in its optical waveguide by the effect of stimulated emission of a fluorescent substance induced by pumped light. According to a first aspect of the invention, an optical amplification system turns on its pumping source 8 when there is an optical signal s1 in the optical waveguide 5 whereas the pumping source 8 is kept off as long as no optical signal s1 is found in the optical waveguide 5 so that, when the pumping source 8 is turned on, pumped light from the pumping source 8 is fed to the optical waveguide 5 with a delay of time relative to the incoming optical signal s1. According to a second aspect of the invention, the inside of the optical waveguide 5 is constantly kept under an excited condition so that, when no optical signal s1 is found in the optical waveguide 5, dummy light s3 is fed to the optical waveguide 5, whereas no dummy light s3 is fed to the optical waveguide 5 once an optical signal s1 is introduced to the optical waveguide 5. With such an arrangement, since no optical amplification takes place at the rising edge of an incoming optical signal and hence the operation of optical amplification is not dependent on the waveform of the incoming optical signal, a safe and stable optical amplification system can be established.

摘要翻译： 提供能够在不受入射光信号的波形影响的情况下工作的光放大系统，用于通过受泵浦光引起的荧光物质的受激发射的影响来放大其光波导中的光信号。 根据本发明的第一方面，当在光波导5中存在光信号s1时，光放大系统接通其泵浦源8，而在源极8中没有发现光信号s1的情况下，泵浦源8被保持关闭 光波导5使得当泵浦源8接通时，来自泵浦源8的泵浦光相对于入射光信号s1以相对于时间的延迟被馈送到光波导5。 根据本发明的第二方面，光波导5的内部恒定地保持在激发状态，使得当在光波导5中没有发现光信号s1时，虚拟光s3被馈送到光波导5， 而一旦将光信号s1引入到光波导5中，就不会向光波导5馈送伪光s 3。通过这样的布置，由于在入射光信号的上升沿不进行光放大，因此， 光放大不依赖于入射光信号的波形，可以建立安全稳定的光放大系统。

摘要： A hydraulic drive system for a civil-engineering and construction machine, includes an unloading valve connected to a discharge line of a hydraulic pump for relieving a hydraulic fluid from the hydraulic pump to a tank when a differential pressure between a delivery pressure of the hydraulic pump and a load pressure of an actuator exceeds a first predetermined value, for controlling the differential pressure. The unloading valve has a spool, a first receiving chamber arranged adjacent to one end of the spool, and a second pressure receiving chamber arranged adjacent to the other end of the spool, the delivery pressure of the hydraulic pump being introduced into the first pressure receiving chamber and the load pressure of the hydraulic actuator being introduced into the second pressure receiving chamber. The unloading valve is provided with a restrictive communication path for selectively communicating the first pressure receiving chamber and the second pressure receiving chamber with each other, whereby when a phase deviation exists between the delivery pressure P.sub.s of the hydraulic pump and the maximum load pressure P.sub.L transmitted to the unloading valve as signal pressures, oscillation of the unloading valve is prevented.

摘要： In a network having a plurality of node apparatus connected to a transmission line, each node apparatus segmenting a transmission message into information blocks of a predetermined length and transmitting them to the transmission line in the form of a fixed length packet (cell) having a source address, each node apparatus sequentially stores packets having different source addresses in vacant memory blocks of a buffer memory. There is written in each memory block the packet data as well as a next address pointer indicating a memory block in which the next received packet having the same source address is stored. When a packet containing the last information block of a message is received, stored in a read address queue is the address indicating the memory block which stores the first information block of the same packet. Reading the first block of a message from the buffer memory is executed in accordance with an address read from the read address queue, and reading the following blocks is executed in accordance with the next address pointer. Read/write of the buffer memory is alternately executed in units of memory block.

摘要： A sensing system using optical fibers having loss characteristics subject to variations of a signal light wave as a pumping light wave with a wavelength different from that of a pumping light wave is coupled into said optical fiber. Unlike conventional OTDRs that utilizes a light back scattering in an optical fiber, a sensing system using optical fibers according to the invention utilizes the light passing through an optical fiber as a detected signal in order to enhance the efficiency and effectiveness of the system and, therefore, it has a significantly improved S/N ratio and a dynamic range of measurement as compared with conventional OTDRs. Moreover, continuous light may be used for the signal light wave (detected signal) to increase the rate of light emission for detection and to reduce the time required for measurement.
