摘要： An embodiment of the invention is an optical node configured to transmit/receive a wavelength-division-multiplexed signal. An optical monitoring unit monitors power levels of the wavelength-division-multiplexed signal on a wavelength-by-wavelength basis to acquire wavelength-by-wavelength power level values of the optical signals. A comparison arithmetic unit performs a comparison between each of the acquired wavelength-by-wavelength power level values of the optical signals, and a predetermined upper limit value and a predetermined lower limit value. A target value calculation unit determines target values of power levels at wavelengths whose acquired power level values exceed the upper limit value to be values between a center value and the upper limit value, and determines target values of power levels at wavelengths whose acquired power level values fall below the lower limit value to be values between the center value and the lower limit value.

摘要： A bearingless hub structure for rotary-wing aircrafts comprising a hub bodyecured to a rotor shaft, a plurality of radially extending flexbeams integrally formed with the hub body, and pitch housings enclosing each of the flexbeams in spaced relationship, the pitch housing having a radially outer end portion rigidly secured to an inboard end of a rotor blade and a radially inner end portion supported by a spherical bearing in the vicinity of a root end of said flexbeam.The flexbeam consists of a flexible element of low lead-lag stiffness and a torsion element of low torsional stiffness located radially outside the flexible element. The flexible element consists of two beam-like members having radially inner ends spaced in the lead-lag direction and extending radially outward with narrowing the distance between them, the beam-like member having radially outer end connected to a radially inner end of the torsion element.

摘要： In an ion implantation system, an ion beam generator generates and emits an ion beam containing ions of a target impurity element. A mass analyzing system derives desired ions from the ion beam to output an ion beam containing the desired ions. The ion beam emitted from the mass analyzing system becomes incident upon an inner cavity defined by a beam line. An electrostatic lens is being disposed in the inner cavity. The electrostatic lens converges the ion beam entered the inner cavity. The ion beam emitted from the beam line impinges upon a substrate into which impurities are to be implanted. A vacuum pump is being mounted on the beam line to evacuate the inner cavity of the beam line.

摘要： A three-dimensional digital map prepared by an satellite or the like is stored in a first memory as a wide-area information. Narrow-area information obtained by a laser radar is stored in a second memory. Obstacle information on obstacles, such as high-voltage power lines, high buildings and cranes, is stored in a third memory. These three information are read out to generate virtual images on a see-through type display mounted on a helmet of a pilot so that the virtual images is superimposed on the actual field of vision.
