Patent number: 8025020Abstract: To provide the auxiliary float of a floating structure which can prolong the lifetime of the floating structure by reducing external force acting on the brace and can be used even at very deep water by increasing buoyancy, and to provide a remodeling method of the floating structure. The auxiliary float (11) comprises two floats (12) coupled, respectively, to lower portions of two lower hulls (1) constituting a floating structure, two main coupling members (13) for coupling the floats (12) to each other, and four sub-coupling members (14) for coupling the main coupling member (13) and the float (12). The auxiliary float (11) is produced in advance and the floating structure is mounted on the auxiliary float (11), and then the lower hull (1) and the float (12) are connected, thus remodeling the floating structure.Type: GrantFiled: July 5, 2007Date of Patent: September 27, 2011Assignee: IHI Marine United Inc.Inventors: Tetsuya Yasuda, Masanori Nemoto, Hiromitsu Yamamoto, Kozo Yokokura

Patent number: 6306481Abstract: A multilayer circuit board having a resolution in the range of 25-80 &mgr;m, and blind via-holes between layers, the blind via-holes having an aspect ratio in the range of 2.0-0.6 for effecting access between the layers, wherein an insulating layer having the blind via-holes between the layers has a glass transition temperature in the range of 150-220° C., and an epoxy group photosensitive resin composition is used therefor. A photosensitive resin composition having a preferable resolution and heat resistance is obtained. A multilayer circuit board is provided in which the thermal stress generated in the steps of a reflow process, a gold wire bonding process and a repairing process in a bare chip mounting process are reduced, and peeling off of the conductor wiring and deformation of the multilayer circuit board caused by mechanical stresses during the heating processes are suppressed. Accordingly, a decrease in the size and weight of an electronic apparatus is possible.Type: GrantFiled: June 22, 1999Date of Patent: October 23, 2001Assignees: Hitachi, Ltd., Hitachi Chemical Company, Ltd.Inventors: Satoru Amou, Masao Suzuki, Tokihito Suwa, Mineo Kawamoto, Akio Takahashi, Masanori Nemoto, Hiroyuki Fukai, Mitsuo Yokota, Shiro Kobayashi, Masashi Miyazaki

Patent number: 5849460Abstract: A photosensitive resin composition for use in manufacture of multi-layer circuit boards with connecting holes between layers is disclosed. The resin composition has excellent adhesion with a plating metal, resolution, photo-curing, thermosetting, thermal resistance, and is capable of being developed using an alkaline solution or an aqueous solution containing a non-halogen based organic solvent as the developing solution. The resin composition comprises a photosensitive epoxy resin, a thermosetting epoxy resin, a reactant of a carboxylic acid added to an acrylonitrile-butadiene rubber and an epoxy resin, a photo-polymerization initiator and a thermosetting agent. This reactant facilitates a high density pattern of connecting holes for circuit boards of the layered type.Type: GrantFiled: July 16, 1997Date of Patent: December 15, 1998Assignee: Hitachi, Ltd.Inventors: Yoshinori Kawai, Mineo Kawamoto, Junichi Katagiri, Masanori Nemoto, Akio Takahashi

Patent number: 4728557Abstract: A molded part including a metal plate formed with a plurality of through holes, a plurality of resin portions connected to a resin filled in the through holes and protruding on opposite sides of the metal plate, the resin portions having a planar cross section larger than a cross section of the through holes, and a plurality of resin components each integrally formed with one of the resin portions. The resin components are secured in place on the metal plate separate from and independent of each other by virtue of residual thermal stress produced by the difference in the coefficient of thermal expansion between the resin portions and the metal plate in such a manner that a radially oriented residual thermal stress in each resin portion is symmetrical with respect to a center axis of one of the resin components.Type: GrantFiled: May 6, 1982Date of Patent: March 1, 1988Assignee: Hitachi, Ltd.Inventors: Hideki Asano, Morimichi Umino, Masanori Nemoto

Patent number: 4445159Abstract: A chassis for video tape recorder molded integrally with a fiber-reinforced plastic composition is light in weight and can meet the requirements for attainment of high precision. It is possible to obtain a chassis with even higher precision and higher rigidity while preventing deformation with time as well as creep deformation, by properly selecting the components of the composition, the number and the position of the gates, and/or the reinforcing measures. In case of using glass fiber as the reinforcing fiber component of the composition, it is desirable to use the type in which 5% by weight or more of the whole glass fiber component is occupied by those glass fibers which have a length of over 1.0 mm and a diameter of 15 .mu.m or less.Type: GrantFiled: November 24, 1981Date of Patent: April 24, 1984Assignee: Hitachi, Ltd.Inventors: Masanori Nemoto, Hideki Asano
