Abstract: A lubricating oil composition for a sliding guide surface, which includes a lubricant base oil, an acid phosphate ester mixture having a structure represented by the following Formula (1) and including an acid phosphate monoester and an acid phosphate diester, and an aliphatic monoamine, and which satisfies a predetermined condition A or condition B, is provided. In Formula (1), each of R1 and R2 represents a hydrogen atom or a saturated or unsaturated straight-chain aliphatic hydrocarbon group having from 1 to 30 carbon atoms, and R1 and R2 are not simultaneously hydrogen atoms.

Abstract: Provided are a liquid ejection cartridge and a liquid ejection device each having a simple structure capable of surely mixing a plurality of liquids. An example of the liquid ejection cartridge includes a liquid ejection portion (12) for ejecting a liquid; a first liquid storage portion (3) which is separated from the liquid ejection portion (12) through a film (10); a second liquid storage portion (4) which is separated from the first liquid storage portion (3) through a film (9). Further, the liquid ejection cartridge further includes a first penetrating member (8) for penetrating the film (10) which separates the liquid ejection portion (12) and the first liquid storage portion (3); and a second penetrating member (7) for penetrating the film (9) which separates the first liquid storage portion (3) and the second liquid storage portion (4).

Abstract: A liquid cartridge of the present invention has a liquid ejection portion 1 for ejecting liquid droplets, a reservoir E1 for storing liquid, and a communicating member 3 for providing communication between both of them. The reservoir E1 has first and second storage portions 10a, 10b isolated by films 6 to 8 arranged spaced from each other and an atmospheric release portion. When a small diameter portion 5a is inserted into an applied concave portion 4 of the liquid ejection portion 1, a tip 3a of the communicating member 3 breaks through the first to third films 6 to 8 sequentially in the period from the beginning to the end of insertion. Consequently, liquid in the first storage portion 10a is filled into the ejection head 2 and thereafter liquid stored in the second storage portion 10b is filled.

Abstract: The shortcomings inherent in prior art coupling fluids are eliminated by combining 1) a polyorganosiloxane fluid as the base oil with 2) sulfur or certain sulfur compounds and 3) at least one cyclic organosiloxane. These three ingredients form a suitable coupling fluid for use in viscous coupling systems.

Abstract: A fiber grid reinforcement is of a flat shape and has first and second directions perpendicular to each other. The fiber grid reinforcement includes a plurality of first fiber bundles, a plurality of second fiber bundles, and a resin material. The first fiber bundles are generally disposed along the first direction and generally parallel to one another. Each of the first fiber bundles includes at least one first group of fibers. The second fiber bundles are generally disposed along the second direction and generally parallel to one another. Each of the second fiber bundles inbcludes at least one second group of fibers. The second fiber bundles intersect perpendicular to the first fiber bundles at intersecting sections so as to form a grid structure. The first group and the second group of fibers are layered alternately at the intersecting sections in such a manner that at least one outermost layer is the second group. The resin material bonds fibers in each group, and bonds the groups to one another.

Abstract: A process for the separation and purification of vinylphenol which comprises contacting crude vinylphenol containing vinylphenol and impurities such as phenol, alkylphenols, vinylphenol polymers and hydrocarbons countercurrently with an aqueous alkali solution together with a specific organic solvent.Vinylphenol obtained is useful as the raw material for the production of polyvinylphenol or a vinylphenol copolymer which is utilized as a thermoplastic resin, an ion exchange membrane, an adhesive, a glass fiber-reinforced composite or the like.
