Title: Ocean sailing vessel designed to prevent adherence of oceanic life
Inventor: SAITOU MASAHIRO
IPC: B63B59/04
Filed: 1981-03-31
Abstract: PURPOSE:To economically and effectively prevent the adherence of oceanic life without allowing to form a pollution resistant film all over the outside shell surfaces of the captioned sailing vessel by forming a thin surface layer of said pollution resistant metal only over the front of the ocean sailing vessel, where friction resistance tends to increase. CONSTITUTION:The front part of carbon steel hull 1 of an ocean sailing vessel, constantly kept in contact with the sea water, i.e, the bow 2, is covered and bonded with an approx. 1mm. thick oceanic life prevention copper plate 4 through an electric insulation layer such as glass cloth from the level about one meter above the draft line down to the bottom of the curved outside shell member. Therefore, the characteristic capacity of the copper plate 4 prevents oceanic life from adhering to the bow 2, and constantly maintains a smooth lower outside surface of the bow 2, which otherwise tends to increase the friction resistance of the hull 1. With this construction, the decrease in speed of vessel and the increase in fuel consumption can be prevented.

Abstract: PURPOSE:To obtain the fire-resisting composition having heat shock resistance, high strength and excellent reaction resistance and percolation resistance against basic materials and alkali salts by specifying the composition of quaternary components system, MgO, Al2O3, SiO2 and ZrO2. CONSTITUTION:The fire-resisting composition is composed of four main components, MgO-Al2O3-SiO2-ZrO2, the sum of the four components in wt.% >=90, MgO >=18.9, SiO2 >=2.0 and ZrO2 >=4.0 and is in the coexistence area of these four components. In case of sum of the four components <90% components such as Ca, Fe, etc., in a raw material react with the four components, MgAl2O4 and Mg2SiO4 to form low melting minerals, thus lowering corrosion resistance. In case of MgO<18.9% no effects on corrosion resistance of glasses, etc., against basic materials are obtained when particle adjustment is done. In case of SiO2 2.0% the amount doesn't reach enough to form a high viscosity composition and it cannot control percolation. In case of ZrO2 4.0% corrosion resistance will be hindered, the amount doesn't reach enough to form a high viscosity composition and percolation resistance will also be lost.

Title: Sound insulating structure
Inventor: NAGATA MAKIO
IPC: B32B5/06
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To increase the sound insulating performance in a low-frequency band by mechanically and thermally processing a surface layer section to form a high-ventilation resistance layer, and setting the ventilation quantity difference between the high-ventilation resistance layer and the other layer within a specific range at a specific air pressure. SOLUTION: A heating process is applied to a surface layer section as a thermal process, the fusion of binder fibers is accelerated, and the binding points of the fibers can be increased. The thickness of a high-ventilation resistance layer is set to the range of 1-10mm. When the thickness is below 1mm, the high-ventilation resistance layer is difficult to manufacture. When the thickness of the high-ventilation resistance layer exceeds 10mm, a low-ventilation resistance layer cannot secure a sufficient thickness, and the sound isolating performance is deteriorated. The ventilation quantity difference between the formed high-ventilation resistance layer and the other layer must be within the range of 400-1400cc/cm<2> .min at the air pressure of 0.01kg/cm<2> . When it is below 400cc/cm<2> .min, a double-wall structure cannot be formed.  When it exceeds 1400cc/cm<2> .min, the target of the sound insulating performance in a low-frequency band cannot be attained.
