Abstract: An antifouling coating composition comprising (A) a silyl ester copolymer containing constituent units derived from a polymerizable unsaturated carboxylic acid silyl ester; (B) a carboxylic acid; (C) a bivalent or trivalent metal compound; and (D) a dehydrating agent. It is preferred that the component (C) be contained in an amount of 1.2 equivalents or more, in terms of the number of equivalents of metal as a constituent of the component (C), per equivalent of carboxyl group of the carboxylic acid (B); that the component (C) be a bivalent metal compound; and that the component (C) be a compound of at least one metal selected from the group consisting of zinc, copper, magnesium, calcium and barium.
Abstract: In the prior art, a user bore a heavy burden on operating together different products having the same functions. A user 102 calls a job net managing function 105 via GUI/CLI 103, and defines a job net 106. A job net execution controlling function 109 interrupts a definition of the job net 106, and sequentially executes the defined jobs. The defined jobs call not real commands directly, but switchers 110 to 114 that define regularized interfaces. The switchers, referring to environment variables 101, select adaptors 115 and 116 properly to call real commands 117 and 118 corresponding thereto.
Abstract: A predetermined contact pressure required between the two metal pieces 60, 70 when they are come into contact with each other is produced by a pressing force of the two metal pieces 60, 70 acting in the direction of height or width of the connector 1. This arrangement prevents the inserted card from coming off and reliably and stably holds the inserted card.
Abstract: The present invention is to lighten the burden imposed on a network manager. In a management host for managing a management object group on a network, a management information storing unit stores management informations containing attribute informations of management objects and has states of the management objects reflected every management object, a network drawing receiving unit receives design drawing data containing symbols correspond to the management objects and has the attribute information of the management object set, a data converting unit generates the management information, on which the states of the management objects corresponding to the symbols of the design drawing data received by the network drawing receiving unit are reflected, from the attribute information of the symbols, and a management information registering unit registers the management information generated by the data converting unit in the management information storing unit.
Abstract: A method for manufacturing a polyimide sleeve where a polyimide sleeve of a high quality can be manufactured easily with a superior yield. A sleeve of a release resin is fitted on a planished metal core or a core at least whose outer surface is made of a release resin, and a polyimide precursor solution is applied on its outer surface. Next, after generating an imide reaction of the polyimide precursor by heating to form an almost completely cured polyimide sleeve, this polyimide sleeve is removed from the core together with the sleeve of the release resin. Furthermore, the polyimide sleeve is separated from the sleeve of the release resin.
Abstract: Disclosed is a silyl (meth)acrylate copolymer which comprises 20 to 80% by weight of (a) silyl (meth)acrylate constituent units (I), 0.01 to 40% by weight of (b) acrylic unsaturated monomer constituent units (II) and 5 to 79.9% by weight of Ĉ unsaturated monomer constituent units other than the constituent units (a) and (b). Also disclosed is a process for preparing the silyl (meth)acrylate copolymer, an antifouling paint composition comprising the copolymer, a coating film formed from the paint composition, a hull with the coating film and an antifouling method using the paint composition.
Abstract: An object integrated management system achieves flexibility for modifications of management targets, efficiency of integrated management processing, and reduction in system management, building, and maintenance costs. The object integrated management system manages real data managed by data management systems in an integrated manner, and comprises: a repository that stores virtual objects respectively created correspondingly to real data, virtual object metamodels defining the virtual objects, adapter objects having configuration information of the data management systems and a function of access processing for real data stored in the data management systems, and adapter object metamodels defining the adapter objects; a metamodel management part that manages the virtual object metamodels and adapter object metamodels within the repository; and an object management part that manages the virtual objects and adapter objects, and uses the adapter objects to access real data.
Abstract: A card connector that reliably holds an inserted card with a compact mechanism to prevent the falling of the card due to unexpected external forces. The card 10 is formed with the recess 18 to receive the locking portion. The elastic locking piece 50 is mounted to the eject member 41 that slides together with the card 10 as the card is inserted or retracted. The locking piece guide means 50b, 61 converts the motion of the eject member 41 in the card insertion/retraction direction into the motion of the locking portion 50c of the elastic locking piece 50 toward or away from the card so that the locking portion 50c is engaged in the recess 18 during the card insertion and, during the card ejection, is disengaged from the recess 18.
Abstract: An electrical connector used for interconnecting one or more conductors on the same or different printed circuit boards comprising two mold members having terminal bodies with each end inserted into the mold members until they protrude from the bottom and with a bent portion between the mold members maintaining a distance greater than the distance required to insert the mold members and terminal bodies into through holes of a printed circuit board. The connector is used in conjunction with a pair of chuck members and a stop member to place the connector mold members in alignment so that the protruding terminal portions can be accurately inserted into through holes of a printed circuit board with the use of automatic robot means.
Abstract: Burner operating air equivalence ratio is monitored and controlled by a method comprising measuring OH radical spectral emission intensity at a base of a flame while combustion is in progress at a burner, employing a linear relationship between the intensity and an actual burner operating air equivalence ratio to determine the ratio while combustion is in progress, comparing the determined ratio with a desired burner operating air equivalence ratio to determine the difference therebetween, and controlling the amount of air supplied to the burner on the basis of the difference.
