Title: Semiconductor laser device
Inventor: IKEDA SOTOMITSU
IPC: H01S5/042
Filed: 1989-04-04
Abstract: PURPOSE:To manufacture a semiconductor laser for dynamic-single-longitudinal mode oscillations having optical wave guides of low loss which are suitable for integration by providing two channels of optical waveguide layers which are combined optically by diffraction gratings and performing current injection from a transverse direction to an active layer. CONSTITUTION:At least the 1st and 2nd optical waveguides 2 and 5 which are used for emitting light and for combining optically with an active layer 4 respectively are provided and both of them are combined optically by diffraction gratings 21 and 22 in which their degree are high, i.e., more than second order. In a dynamic-single-longitudinal mode oscillation laser that is manufactured in this way, carriers are injected horizontally from a transverse direction to the active layer 4 and then the carriers combine each other again in an active waveguide to emit light. Distributed feedback of light emitted is performed by the diffraction gratings of the 2nd optical waveguides 5 and its light combines optically with the 1st optical waveguide 2. Then it is induced and emitted in an active region by being reflected in the form of distribution. The waveguides of oscillating light become uniform and even when amplitude modulation takes place, they may oscillate at a stable, dynamic-single-mode.

Title: Radar reflection reducing device for aircraft and the like
Inventor: SHINGOU MIKA
IPC: F41H3/00
Filed: 1991-04-16
Abstract: PURPOSE:To reflect radio wave regardless of the rear rim of a predetermined body to make acquisition by radar difficult by a method wherein an electroconductive thin film layer, whose rear end rim with respect to the estimated comming direction of radar waves is formed so as to be oblique with respect to the direction of the radar wave, is bonded on the outer surfaces of the predetermined body. CONSTITUTION:An electroconductive foil 3 is bonded on the surface of the main wing 2 of an aircraft 1. The rear end rim of the electroconductive foil 3 is cut and aligned with a different angle from the sweepback angle of the main wing 2. When radar wave 4 is projected from the front direction of the aircraft 1, an induced electric current 5, generated on the upper surface of the main wing 2, arrives at the rear end rim 8 of the electroconductive foil 8 before it arrives at the rear end rim 7 of the main wing and reflected radio wave 6 is formed by the discontinuous reduction of conductivity. The direction of the reflected radio wave 6 is the same as in the case, in which the plane configuration of the main wing 2 is only a part covered by the electroconductive foil 3. Accordingly, the reflecting direction of the radar wave 4 can be changed without changing any sweepback angle of the main wing 2. Accordingly, acquisition by radar can be made difficult without spoiling any characteristic of the main wing 2.
