Filed: 1987-01-27
Abstract: PURPOSE:To correct the lowering in the output of a road surface reflecting apparatus due to the contamination of said apparatus, by providing a contamination correcting beam receiving element and detecting the attenuation quantity of beam due to contamination. CONSTITUTION:A part 14a of the beam of a beam source 2 is incident to a condenser lens 6 by a beam splitter 4 to be transmitted by an optical fiber 5 and converted to parallel beam 14b by a collimator lens 7 to be emitted. The parallel beam 14b is incident to a lens 8 and reflected by the mirror surface 9a of a prism 9 to transmit through the surfaces 9b, 9c of the prism 9 and reflected by the mirror surface 9d thereof to advance through the lens 8 and condensed to a contamination correcting beam receiving element 10. Now, when a contaminant 18 is adhered to the surface of the lens 8 and the surfaces 9b, 9c of the prism 9, luminous flux attenuates and the output signal of the element 10 lowers. The transmissivity at that time is calculated to correct the output signal of a signal detecting beam receiving element 11 and the effect due to the attenuation of beam caused by the surface contamination of the lens or window glass of a road surface reflecting apparatus can be corrected.

Title: Optical amplifier
Inventor: ONO HIROTAKA
IPC: H04B10/294
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To control the gain of a signal light to be constant, by making the signal light of optional integer wavelength a monitor signal light, and performing the adjustment so that the gain of signal light may come to a fixed value in case of the singular wavelength, and adjusting the quantity of excited light so that the average value of the ripple of the gain of signal light may be minimum in case of a plurality of wavelengths. SOLUTION: Out of the signal lights of n wavelength (n is an integer not less than 1), the signal light of optional m wavelength (m is an integer not less than 1 and not more than n) is made a monitor signal light. This gain control decreases the quantity of excited light so that the gain of the signal light of monitor wavelength may come to a fixed value, making one signal wavelength 1570 nm or the like the monitor wavelength. Hereby, the maximum gain ripple can be suppressed to about 0.2 dB (1598 nm) in all channels, and even in case that the monitor wavelength is changed to 1598 nm or the like, the maximum gain ripple can be suppressed to about 0.5 dB or under. Moreover, it becomes the same results, even if it monitors two waves or more, and controls the average value of the ripple of the gain of each signal light to be minimum. Hereby, the gain can be controlled to be constant.

Title: Manufacture of rare earth-iron permanent magnet
Inventor: YAMASHITA FUMITOSHI
IPC: H01F1/055
Filed: 1989-01-27
Abstract: PURPOSE:To maintain and ensure the same shape arbitrariness and thermal stability as a resin magnet and realize a rare earth-iron permanent magnet having performance superior to the magnetic stability of a hot press magnet by making a rare earth-iron thin piece obtained by ultra-quenching be an aggregate of an arbitrary shape and by fixing the thin films. CONSTITUTION:By using DC discharge used as a method of generating discharge plasma, an aggregate of a rare earth-iron thin piece obtained by ultra-quenching is made to transit to an active state, and thereafter is resistance-sintered. Therefore, since not only a rare earth-iron permanent magnet of an arbitrary shape can be obtained very speedily, but the production or/and growth of phase B of R2Fe(Co)14 is suppressed, the thermal stability of a permanent magnet is not degraded due to a considerable decrease in the specific coercive force Hcj of the original thin piece or in its temperature coefficient. Further, since a plastic deformation of the thin piece is promoted, partial magnetic anisotropy in a pressure axial direction progresses, and high magnetic performance can be ensured.
