Abstract: A silicate mixture and a combustion accelerator increase combustion efficiency in a combustion engine. The silicate mixture is formed by mixing a first component including one or two or more materials selected from silicon compounds including silicon, glass, and quartz, and a second component including one or two or more materials selected from materials formed by sintering a silicate mineral at a temperature of 1300° C. or higher and 2000° C. or lower and ores emitting a terahertz wave.

Abstract: Provided are a silicate mixture and a combustion accelerator for increasing combustion efficiency in a combustion engine. The silicate mixture is formed by mixing a first component including one or two or more materials selected from silicon compounds including silicon, glass, and quartz, and a second component including one or two or more materials selected from materials formed by sintering a silicate mineral at a temperature of 1300° C. or higher and 2000° C. or lower and ores emitting a terahertz wave.

Abstract: A first sealing member and a second sealing member are disposed respectively on a lower mold and an upper mold. During a process of closing the lower mold and the upper mold, a gap between the molds is sealed by the first sealing member, thereby forming an enclosed space between the molds. Thereafter, a gas in the enclosed space is discharged. As the closing process progresses, the enclosed space is divided by the second sealing member into a sealed room and a production cavity, followed by a liquid resin being supplied to the production cavity.

Abstract: In a molding method and an apparatus for the method, a base material is placed on mounting portions of bottom support pins, which protrude from a first inner surface of a lower mold in an open state. Pressing portions of top support pins, which protrude from a second inner surface of an upper mold, are brought into contact with the base material. Consequently, the base material is sandwiched between the mounting portions and the pressing portions. Thereafter, pre-forming preferably is carried out. For example, the bottom support pins and the top support pins are lowered toward the lower mold, such that the base material is brought into contact with the first inner surface. Then, the lower mold and the upper mold are closed, and the base material is molded into a molded article.

Abstract: A method for bonding a plurality of non-magnetic members includes the steps of (1) mating the non-magnetic members via an uncured adhesive interposed between their surfaces to be bonded; (2) applying pressure to their mated portions between a pressing magnet jig and a pressure-receiving, soft-magnetic jig; and (3) curing the adhesive while applying pressure.

Abstract: A honeycomb sandwich panel is produced by (a) mounting a honeycomb core on a lower prepreg laminate skin placed on a forming die, (b) superimposing thereon an upper prepreg laminate skin to cover the honeycomb core, (c) mounting flat plate-shaped elastic jigs on a portion of the resulting assembly where the lower prepreg laminate skin and the upper prepreg laminate skin are overlapping each other, (d) superimposing flat plate-shaped press jigs on the elastic jigs, and (e) heating the assembly under pressure for adhesion forming.

Abstract: A method for efficiently producing a stiffened hollow structure from a first skin member, a second skin member and a stiffener each made of a fiber-reinforced composite with reduced steps, the stiffened hollow structure comprising a hollow skin portion and a stiffening portion for strengthening the hollow skin portion from the inside. The method comprises the steps of: (1) disposing the first skin member and the second skin member on the stiffener, an adhesive being provided between the stiffener and each of the first skin member and the second skin member; (2) placing a band on the outer surface of the first skin member and the second skin member; and (3) setting the adhesive while tightening the band and applying a tensile force to the first skin member and the second skin member.
