Title: Light pulse train generator
Inventor: ITO HIROKI
IPC: G02F1/35
Filed: 1988-04-22
Abstract: PURPOSE:To reduce the cost of the device and to generate light pulse trains which are highly stable over a long period of time by executing the repetitive adjustment of frequencies by the selective amplification of a modulation side wave band. CONSTITUTION:The feed back loop constituted of an optical fiber 4 an refractive index coupler 5   an optical fiber code 7   an objective lens 8  a diffraction grating 9   a space filter 11   an objective lens 12   an optical fiber coupler 3   an optical fiber 4 acts as the resonator to the light of the wavelength in the modulation side wave band. The light is amplified by the modulation unstable effect of the optical fiber 4 and the self-amplification modulation to a carrier light wave is deepened. Further, the light is made into the pulse trains by the above-mentioned amplification coupled with the soliton pulse effect possessed by the optical fiber 4. These pulse trains are outputted as light pulse trains via the optical fiber coupler 4 and the objective lens 6. The generation of the light pulse trains at the low cost with high reliability is thereby enabled.

Title: Rush-mat crease removal method
Inventor: TANAKA TADASHI
IPC: E04F15/02
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To remove a crease without causing any drop in elasticity and strength, as well as without causing any appearance of a new crease, gloss, glaze or the like by applying the constitution that a rush-mat is made to contain the prescribed amount of water, left as it is over the preset time and dried under tension. SOLUTION: A rush-mat having a plurality of rows of strong and weak creases is laid on a rush-mat base, and tension is applied across both ends thereof. Then, each end of the rush-mat is fixed to the stile of the base with marking pins, with the rush-mat kept under tension. In this state, 150 ml/m<2> or more, or preferably 180 ml/m<2> or more of water or preferably charcoal water is sprayed to and contained in the whole surface of the rush-mat. Then, the rush-mat is left as it is over the preset time. Subsequently, the rush-mat is naturally dried at temperature equal to or lower than 40 deg.C and, then, dried at high temperature equal to or above 60 deg.C. As a result, any of the strong crease and the weak crease becomes almost invisible on the rush-mat. Furthermore, elasticity and strength do not drop, and a new crease, gloss, glaze or the like does not appear.
