Title: Vehicle azimuth detector
Inventor: ITOU TAKENORI
IPC: G01C21/12
Filed: 1992-09-30
Abstract: PURPOSE:To prevent the generation of a large error in the azimuth of a vehicle even when front wheels slip. CONSTITUTION:The numbers of rotations of left and right front wheels M1, W2 are detected by wheel sensors 1A,1B and a handle steering angle is detected by a steering sensor 2. A vehicle azimuth operation device 3 calculates wheels azimuths from the detected numbers of rotations of the front wheels and calculates a steering azimuth from the handle steering angle. The wheel azimuths and the steering azimuth are compared and, when the wheel azimuths are within a predetermined range with respect to the steering azimuth, the wheel azimuths are outputted as a vehicle azimuth and, when the wheel azimuths are not within the predetermined range, the steering azimuth is outputted as the vehicle azimuth. When the front wheels slip, the wheels azimuths are largely different from the actual vehicle azimuth and become large so as to exceed the predetermined range with respect to the steering azimuth. In this case, the steering azimuth is used as the vehicle azimuth and the error with the actual vehicle azimuth is suppressed to the min.

Title: Light amplifier
Inventor: KOGA MASABUMI
IPC: H04B10/291
Filed: 1987-11-14
Abstract: PURPOSE:To obtain a constant gain with respect to injected light without depending upon the state of polarization of the light by mutually crossing the thickness directions of active layers in two semiconductor laser elements arranged onto the same optical path in a cascade manner at right angles to the deflection of light on the optical path. CONSTITUTION:Light propagated in a single-mode optical fiber 1 is injected to an active layer 4 in a light amplifier 3 through a SELFOC lens 2, and amplified respectively to TE waves and TM waves only by gains GTE1, GTM1 and output. Amplified light is injected to an active layer 7 in a light amplifier 6 through a lens 5'', and amplified respectively only by gains GTE2, GTM2 and output. When an optical isolator 10 having no polarized wave dependency is inserted between the light amplifiers 3, 6, light returns to the light amplifier 3 at a pre-stage owing to the incompleteness of a nonreflective film, thus preventing the generation of the increase of noises and the saturation of gains. When an optical filter is used at an outgoing end, the quantity of spontaneous emission light of the light amplifier 3 is reduced.
