Title: Method of throwing foundation stone onto water bottom
Inventor: SHIYUDOU YASUNOBU
IPC: E02D15/10
Filed: 1978-12-27
Abstract: PURPOSE: To accurately throw foundation stones inside of a throw-in area even in the deep water.  
     CONSTITUTION: A guide 2 is sent to a predetermined position at the sea bottom by partly filling a buoyancy tank 3 after expanding the spaces between ejection pipes 4, 10 and 11 by extending out wire ropes 7, and the buoyancy tank 3 is located at a reguired depth under the sea level by controlling the drawn out length of the wire ropes 7 so as not to prevent novigation of drump ships 25 or the like. On this occasion, sinkers 6 land at the sea bottom so as to prevent the guide 2 from moving sideways. The foundation stones 26 are then thrown inside water flow film formed above required part of boundary of the foundation stone throw-in area at the sea bottom by ejecting the water supplied with a pump 20 as indicated with 4, 10 and 11.

Filed: 1983-09-07
Abstract: PURPOSE:To elevate the measuring accuracy of plane level by coaxially using an optical path in common for the entire effective diameter of an object lens both in the light transmitting optical system and the light receiving optical system. CONSTITUTION:According to a command from a measurement control circuit 35, first, the calibrated optical path length is measured when light emitted from a light emitting diode reciprocates in reflection on a eflection sheet 7 on the back of a shutter plate. Then, the shutter plate 6 is opened with a motor 10 to measure the external optical path length up to the water surface. By a final measuring command, the shutter plate is returned to the original closed position to complete a single measurement. Meanwhile, an arithmetic unit 34 in an electric circuit subtracts the internal optical path length from the external optical path length and the real measured value is shown on a display 36 or recorded with a recorder.

Abstract: PURPOSE:To enable the focusing or spreading of light without executing of three-dimensional working by constituting a lens body of such a material, the refractive index of which changes continuously from a central part diametrally toward the outer side. CONSTITUTION:The lens body 2 formed on a substrate 1 is a thin-film convex lens constituted of such material which is low in the refractive index in the central part and is increased in the refractive index diametrally toward the peripheral part. The lens body 2 is constituted of such material having the refractive index changing continuously from the central part diametrally toward the outer side and, therefore, the focusing and spreading of the light are possible without executing the three-dimensional working. The miniaturization and the enhancement of quality are thus possible. This process for production consists in depositing either of a high-refractive index material and low-refractive index material by evaporation at equal beam intensity over the entire surface of the lens forming part on the substrate 1 and simultaneously depositing either of the high-refractive index material and low-refractive index material in such a manner that the beam intensity is high in the central part of the lens forming part and is low in the peripheral part.
