Patent JP-S60198887-A (JP)
Title: Light amplifier
Inventor: SHIRASAKI MASATAKA
IPC: H01S3/23
Filed: 1984-03-23
Abstract: PURPOSE:To directly amplify light and to obtain a large amplification factor by a method wherein a light to correspond to one of multiplex modes is made to incide in a laser, which oscillates on the multiplex modes, and the light is amplified in the laser. CONSTITUTION:A laser 1 can oscillate two modes of a TE mode and a TM mode, both having the same frequency, and a dichroic material 2 disposed in the optical resonator has a slightly larger absorption factor of the TE mode than that of the TM mode in the two modes. The laser 1 oscillates in the TM mode when there is no incident light 3 from the exterior. A ploarizer 4 allows a light alone of the TE mode to transmit and intercepts a light of the TM mode. Therefore, when there is no incident light 3, no light emits from the polarizer 4. When the incident light 3 of the TE mode is made to incide in the laser 1 from the exterior, the incident light is amplified in the laser and after receiving attenuation in the dichroic material 2, the incident light is reflected by the reflecting mirror of the resonator and is further amplified by reciprocating the interior of the resonator.

Filed: 1986-03-14
Abstract: PURPOSE:To separate specific gas by low energy, by allowing a gaseous mixture to flow so as to provide a speed component vertical or parallel to the direction of an AC electric field and generating an AC magnetic field of a vertical component in an area where the AC electric field and said gas are present. CONSTITUTION:An AC electric field E is generated between electrode plates 10, 12 provided so as to be opposed to each other. A coil 14 for generating an AC magnetic field B is provided outside the electrode plates 10, 12 and the AC magnetic field B proportional to a coil current is applied. When a gaseous mixture 16 is made to flow to the direction shown by an arrow A at a low speed between the electrode plates 10, 12, the gas molecules of the gaseous mixture are separated toward the electric field direction by the AC electric field E and this time differentiation comes to be a current. Gas molecules receive deflection toward the surface of paper by Lorentz force based on the action of the AC magnetic field B due to an exciting current having the same frequency and phase as those of said current. By this method, gas molecules having mass difference can be enriched or separated.

Abstract: PURPOSE:To prevent the electric discharge between a high-frequency induction heating coil and a crystal rod and obtain a crystal, melting the crystal rod with a divided concentrator in which the respective electrical central points are connected to give the same potential in the crystal rod. CONSTITUTION:A current (I) indicated by an arrow in an induction heating oil 2 is not used directly for melting a crystal rod 1, and an induction current (I') indicated by arrows in divided parts (5a) and (5b) of a concentrator 5 is used for melting the crystal rod 1. In the process, the respective electrical central points (4a) and (4b) of the divided parts (5a) and (5b) of the concentrator 5 are connected to the inner wall of a melting chamber with connections 3. Thus, the inner wall of the chamber is electrically connected to the crystal rod 1 as shown by a connection 3', and the maximal potential difference between the crystal rod 1 and the divided parts (5a) and (5b) becomes (1/4) of the potential 6 across the induction heating coil electrodes. The concentrator 5 is not only halved as mentioned above but also can be divided into many parts. The potential between the concentrator 5 and the crystal rod 1 can be reduced further if necessary.

IPC: G02B6/13
Filed: 1994-03-28
Abstract: PURPOSE:To provide a manufacturing method for an optical waveguide by which the optical waveguide whose substrate is not deformed is formed without increasing the number of manufacturing processes and an optical waveguide whose substrate is not deformed. CONSTITUTION:At a step 2, the film of a mask material 3 is formed on the substrate 1. At a step 3, the mask material 3 is patterned so that the width of the optical waveguide becomes 4mum and the width of a mask becomes 15mum. At a step 4, the substrate 1 covered with the mask material 3 is immersed in benzoic acid 5 and ion is exchanged. At a step 5, the substrate 1 is annealed in an electric furnace and the exchanged ion is diffused. Thus, the optical waveguides 2a and 2b are formed at the aperture parts 4a and 4b of the mask material 3 on the surface of the substrate 1 and all the ion is exchanged at the other aperture parts 4c, 4d and 4e. Besides, the ion is exchanged on the whole of the back surface. As the result, the difference of the area of the parts where the ion is exchanged, becomes small on the front surface and the back surface and the deformation of the substrate 1 such as warp is not caused. Besides, the substrate 1 is manufactured by a small number of processes.

Abstract: PURPOSE:To improve safety without causing a willey (floating up of front wheel) condition by providing a rotating direction changing member for changing a rear-wheel side sprocket in the reverse direction between the rear-wheel side sprocket and a rear wheel. CONSTITUTION:A sprocket 2 on an engine 1 side, an endless flexible member 5 and a sprocket 4 on a rear wheel 3 side are rotated in the reverse direction and, after the rotation of the sprocket 4 is further changed in the reverse direction by means of a rotating direction changing member 6, the rotation is transmitted to the rear wheel 3. At this time, the moment which acts on the sprocket 2 on the engine 1 side via the endless flexible member 5 at the time of driving the rear wheel 3 acts in the direction of grounding a front wheel 9 as shown by the void arrow. Hence, even if the rotation of the engine 1 is suddenly transmitted to the rear wheel 3, a willey condition in which the front wheel 9 is floated up does not take place, enabling safe driving even by an unskilled person without incurring the dangerous condition of the willey.
