Abstract: A floating body for an offshore wind turbine includes: one first column; two second columns; two lower hulls connecting the first column to each of the second columns; and a beam member connecting the two lower hulls. The beam member is disposed within a height range between an upper surface and a lower surface of each lower hull.

Abstract: A process for purification treatment of wastewater according to the present invention is a process for conducting a purification treatment of wastewater containing polyvinyl alcohol by using a membrane bioreactor process, the process including adding a nutrient to a treatment system. The nutrient is preferably added to an aeration tank. The nutrient preferably contains nitrogen. An amount of the nutrient initially added is preferably 5% or more and 25% or less in terms of nitrogen. The process for purification treatment of wastewater preferably includes a step of measuring a nitrogen content after a treatment, and an amount of the nutrient added is preferably adjusted on the basis of the result of this measurement while checking the effect on the basis of a chemical oxygen demand. The nutrient may be added to the aeration tank by a mechanism that adds the nutrient to the treatment system or by feeding the nutrient manually to the treatment system.

Abstract: An optical recording medium is produced in which air trapping or air bubbling in a resin layer is suppressed, and the resin layer formed has a uniform thickness. A disk cap member 9 having an diameter greater that the diameter of a central hole 2 of a circular substrate is placed on a recording medium 1 provided with the circular substrate so as to close the central hole 2, while a resin film A prepared by curing a liquid resin material a that covers a step formed by the cap member 9 and the recording medium 1 is formed. On the cap member 9, a curable resin material c for forming a resin layer 11 is supplied, and the recording medium is rotated to spin-spread the curable resin material c. During or after the spin spreading, the curable resin material c is cured so that the resin layer 11 is formed on the recording medium 1.

Abstract: An optical information recording medium for recording, retrieving and erasing mark length-modulated amorphous marks, which comprises a substrate, and a lower protective layer, a phase-change recording layer, an upper protective layer and a reflective layer having a thickness of from 40 to 300 nm and a volume resistivity of from 20 to 150 n.OMEGA..multidot.m, formed in this sequence on the substrate.

Abstract: A hierarchical processing system includes processors connected in a hierarchical formation having first, second and third hierarchical levels, for down loading information to the processors in parallel. The system comprises a memory unit provided at the first hierarchical level, for storing information to be down loaded to the processors located at the second and third hierarchical levels and for receiving configuration data about the processors located at the second and third hierarchical levels therefrom, a receiving unit provided at the second hierarchical level, for receiving the information to be down loaded to the processors located at the second and third hierarchical levels from the memory unit and for sending the configuration data about processors located at the second and third hierarchical levels to the memory unit.

Abstract: A facsimile communication system includes a transmitter for transmitting data in a state where a minimum value of a total amount of data to be transmitted for each scanning line is secured, the data for each block including image data, and a receiver for receiving the data transmitted from the transmitter.

Abstract: A liquefied carbonated gas abyssal casting apparatus prevents freezing at an outlet of a casting tube and flotation of cast carbonated gas. The liquefied carbonated gas is fed from a reservoir to a single casting tube and discharged to the abyss through an inner tube of a double casting tube from a lower end of the single casting tube. A heat medium fluid is recirculated between the inner tube and an outer tube of the double casting tube. The liquefied carbonated gas which flows through the inner tube is heated to an abyssal temperature of from -1.degree. to 5.degree. C.

Abstract: A communication terminal connected to a line of an exchange of a public network, includes a main body of the communication terminal, and a line branching detection controller coupled to the main body. The line branching detection controller includes a communication state detector enabling the communication terminal to call and receive a call when a communication operation of the communication terminal is detected, a line signal monitoring part activated when the communication state detector detects no communication operation and monitoring signals on the line connected to the exchange when activated, and an interference signal generator driven when the line signal monitoring part detects a signal indicating a communication made on the line and generating an interference signal on the line when driven.

Abstract: A multi-ferrule structure comprising a plurality of ferrule units each for a single optical fiber. The ferrule units are disposed in contact with an adjacent one(s) in such a way that the respective axes of the ferrule units are in parallel with each other in one and the same plane. The ferrule units make one multi-ferrule set. The maximum deviation of the distance between optical axis of the optical fibers inserted in the respective ferrule units of the multi-ferrule set is very small. When a number of optical fibers are connected with the same number of other photoconductive components by using the multi-ferrule structure, the positioning accuracy for abutting connection is remarkably improved. In addition, the multi-ferrule structure becomes small in size and compact one.
