    摘要： Provided are a small-sized, low-cost, and easy-to-use laser optical path length difference detecting device, a laser optical path length difference detecting device, and a coherent optical coupling device. The laser optical path length difference detecting device detects an optical path length difference between propagation paths of a first laser beam (1) and a second laser beam (2), which are mutually coherent when the beams are propagated through two arbitrary optical paths of a plurality of laser beam optical paths. The laser optical path length difference detecting device is provided with an optical path length difference variable means (4) for changing the optical path length difference between the first laser beam (1) and the second laser beam (2), a wavefront inclination generating means (5) for inclining a wavefront of at least one of the first laser beam (1) and the second laser beam (2), and a two-dimensional detector (6) for detecting the interference light intensity distribution of the first laser beam (1) and the second laser beam (2) which have passed through the wavefront inclination generating means.

    摘要： A method and apparatus for selecting paths to route incoming traffic through a data communication network, which is capable of effectively dispersing the traffic load to the selected paths on the network and effectively optimizing the use of network resources. In a communication network, a plurality of label switched paths between an ingress node and an egress node are provided. Incoming traffic at the ingress node is labeled and delivered through the network to the egress node. In a method and apparatus for selecting paths to route the incoming traffic through the network, a plurality of forwarding equivalent class elements (FEC) of the incoming traffic at the ingress node are allocated for the plurality of label switched paths. The labeled traffic is delivered on the plurality of label switched paths on an FEC-element basis so as to route the labeled traffic through the network to the egress node. The traffic load on the respective label switched paths can be effectively dispersed and the sequence of data packets, sent by the same terminal, may be maintained.

    摘要： The rays of light from an object under observation are condensed by objective lens. The incident light from the objective lens is reflected by plane reflector mirror to form a focused image on a detector. The plane reflector mirror floats in at least three reflector mirror floating vessels and even if the telescope tilts, a surface of the fluid in the vessel remains leveled and the plane reflector mirror does not vibrate. Further, the plane reflector mirror includes at least three pads, each of the pads floating in a corresponding reflector mirror floating vessel.

    摘要： A phase difference detecting device includes a splitter for splitting laser beams into a first group which will travel along a first path and a second group which will travel along a second path, a beam selection/extraction unit for selecting, as reference light, one beam from the first group to allow it to pass therethrough, a path length changing unit for changing the length of the first path, a combining unit for combining the reference light and beams which construct the second group to produce interference light, and a detector for detecting the intensity of the interference light. The device changes the length of the first path using the path length changing unit to detect a path length which maximizes the intensity of the interference light for each of the beams which construct the second group, and determines a phase difference among the beams from the detected path length.

    摘要： A computer-readable recording medium recording a service control program whereby providable services can be determined by using highly secure information. A device detector collects, via a controller, service profiles of devices connected to a network, and also acquires identification information of the controller. A usage condition acquisition unit acquires, from a management database, usage conditions for using nearby devices. An available service decision unit determines available services which can be provided by one or more devices including those on the network and which meet the usage conditions. A device controller remotely controls the device which is used for providing an available service among those determined by the available service decision unit, to provide the available service.

    摘要： A readhead control mechanism serves to control a readhead included in an optical encoder that measures a mechanical displacement between a fixed portion and a movable portion by reading out a gradation mark on a scale provided on the fixed portion, by using the readhead that is provided on the movable portion. The readhead mechanism includes a securing member that secures the readhead onto the movable portion, an actuator that is directly or indirectly secured onto the readhead to shift the readhead in an approaching direction or in a distancing direction, and an actuator controller that controls the actuator to maintain a constant distance between the readhead and the scale.
