摘要： The optical amplification gain of an optical amplifier consisting of an optical amplifier unit and a single-mode erbium-doped fiber can be optimized when the length of the fiber L in meters and the optical absorption in dB/meter of the fiber per unit length at a wavelength of 1.53 .mu.m satisfy the relationship that L.times.y is in the range from 70 to 170 dB by appropriately selecting the doping level of the glass with erbium and the length of the fiber.

摘要： A novel method is proposed for the preparation of a transparent fused silica glass body co-doped with a rare earth element and aluminum each in a high uniformity of the dopant distribution. The method comprises the steps of: (a) flame-hydrolyzing a silicon compound and an aluminum compound in an oxyhydrogen flame to form a porous silicon oxide body containing aluminum; (b) soaking the porous body having a specified bulk density with a solution of a rare earth compound; (c) drying the solution-soaked porous body; and (d) sintering and vitrifying the dried porous body into a transparent glass body.

摘要： In a long-distance high-speed optical communication scheme in which multiple optical amplifiers are provided at a large number of stages in optical fibers, an optical signal from a light source which has a desired small line width and oscillates at a single wavelength is modulated at a high speed by an external modulator and then transmitted in the fibers which are dispersion shifted optical fibers, the zero-dispersion wavelength in which is set to be larger than the oscillation wavelength of the light source. Therefore, noises and the modulation instability, which would occur due to the phase fluctuation in the oscillation wavelength of the light source, and the influence of a waveform distortion due to the dispersion in the optical fibers can be avoided to make it possible for the first time in history to transmit the optical signals at the high-speed in the long-distance optical communication system employing the optical amplifiers.

摘要： An ultrathin cross-roller bearing composed of outer and inner rings, more than one roller rolling through between the outer and inner rings, and a separator interposed between any two adjoining rollers. With the ultrathin cross-roller bearing constructed as stated earlier, the separator lying between the adjoining rollers is in the form of right cylinder better for keeping constantly the roller in proper posture, getting the bearing itself downsized and lightweight as small as possible, and further making sure of positive lubrication. The outer and inner rings are each made into one-piece construction. The inner ring has an inside diameter in a range of from 20 mm to 50 mm. The roller used in the ultrathin cross-roller bearing has a diameter of 2 mm to render a transverse section given by a product of a radial height and a bearing width in transverse section small or ultrathin in thickness.

摘要： A lubricating structure for a hydrostatic continuously variable transmission. The structure includes an oil path arranged at an outer circumferential side of a clutch valve, and a lubricant oil ejection hole communicating with the outer circumferential side oil path of the clutch valve and formed in the transmission shaft toward the outer circumference of the transmission shaft. In addition, the structure includes a communicating oil path that is also formed in the transmission shaft for communicating between an oil feeding passage communicating with an lubricant oil feeding source and the outer circumferential oil path of the clutch valve. A single orifice is arranged in the communicating oil path, rather than in the lubricant oil ejection hole. This configuration provides for efficient manufacturing and a high degree of freedom in setting of the lubricant oil ejection hole.

摘要： A hydrostatic continuously variable transmission includes a hydraulic pump and a hydraulic motor, supported by a common support shaft, and hydraulically connectable to each other through a hydraulic circuit including an inside passage and an outside passage. A clutch device includes a valve spool, which is slidably disposed in a hollow internal bore formed in the transmission support shaft. The valve spool is operable to make or interrupt fluid communication between the inside passage and the outside passage, according to the movement thereof. A governor mechanism is mounted to a pump casing of the hydraulic pump, and the governor mechanism generates a governor force corresponding to the rotating speed of a clutch cap, by use of centrifugal force generated by the rotation thereof. The valve spool is effectively moved in the hollow internal bore, using the governor force generated from the governor mechanism, to engage or disengage the clutch.
