Abstract: A timing transmission mechanism (T2) in an engine is formed of a chain transmission system (C) that is formed from a drive sprocket (20) mounted on a crankshaft (4), a driven sprocket (25) mounted on a pump input shaft (24) of a high pressure fuel pump (P), and a chain (22) wound around the drive sprocket (20) and the driven sprocket (25); and a gear transmission system (G) that is formed from a drive gear (26) mounted on the pump input shaft (24) coaxially with the driven sprocket (25) and a driven gear (27) mounted on a camshaft (13b) and meshing with the drive gear (26). This enables a timing transmission mechanism to be provided that can increase the degree of freedom in layout of the high pressure fuel pump without causing any increase in the number of components, the weight, or the backlash.

Abstract: A cover member fastening method and fastening structure are provided which can surly fasten and fix an abutting portion needing firm abutment and fixing and suppress a deformation of the cover member while suppressing a transmission of vibration to the cover member by further reducing the contact area with an engine body. In a fastening structure for a head cover (2) fastened to a cylinder head (1) by a fastening member (7) so as to cover the upper face of the cylinder head (1), an abutting portion (27) that abuts the upper face of the cylinder head (1) is formed on the internal face of the head cover (2). The lower face of a head-cover-side fastening boss (26) protrudes beyond the lower face of a head-cover-side attaching flange (22).

Abstract: A large number of microscopic recess portions are formed on a surface of a glass substrate in a single dimension or two dimensions by conducting a wet etching through a mask. The large number of microscopic recess portions are aligned densely by again conducting the wet etching but not through the mask. A separating agent is applied upon the surface of the glass substrate and a light-curable or heat-curable resin material of high refractive index is applied thereon. The high refractive index resin material is cured, after piling a first glass substrate upon the high refractive index resin material so as to extend the high refractive index resin material thereon. The high refractive index resin material which is cured and the first glass substrate are separated from the glass substrate, and a low refractive index resin material is applied on the high refractive index resin material which is cured on the first glass substrate.

Abstract: A coated plastic molded article comprising a plastic molded article on the surface of which are laminated (a) a first layer comprising a cured composition containing a partially hydrolyzed product of at least one silicon compound, (b) a second layer comprising a cured, partially hydrolyzed product of a second silicon compound, and (c) a third layer comprising silicon dioxide from an aqueous hydrosilicofluoric acid solution supersaturated with silicon dioxide, the coating layers being applied to the plastic molded article in the order stated; and alternate embodiments of a process for preparing the coated plastic molded articles.

Abstract: A plastic lens formed by laminating, in the order as described below,(A) a plastic lens substrate having a refractive index in the range of 1.50 to 1.70,(B) a primer layer containing a metal compound of at least one metal selected from the group consisting of Al, Ti, Zr, Sn and Sb and a polyurethane, or(B') a primer layer formed from a polyurethane containing at least one element selected from the group consisting of Cl, Br, I and S,(C) a hard coating layer, and(D) a single-layered or multi-layered anti-reflection layer formed by vapor-depositing an inorganic substance.

Abstract: An inorganic or organic glass product, or tempered glass product excellent in weatherability, water resistance, moisture resistance and abrasion resistance, which is formed of a) a silicate glass substrate, b) a porous modified layer enriched with silicon oxide through removal of components other than silicon oxide in a surface layer of the silicate glass substrate, and c) a water-repellent layer formed of at least one compound of an organic silicon compound and an organic fluorine compound on a surface of the porous modified layer.

Abstract: A process for producing a light control plate which selectively scatters incident light of a specific angle, which comprises:(1) bringing at least one photopolymerizable compound of a photopolymerizable monomer and a photopolymerizable oligomer into contact with a transparent plastic film or sheet, each of the monomer and the oligomer having a polymerizable carbon-carbon double bond and being capable of forming a polymer having a refractive index different from a refractive index of said transparent plastic film or sheet, to allow said photopolymerizable compound to infiltrate into said transparent film or sheet through a surface of said transparent film or sheet, thereby forming a swollen surface layer, and(2) irradiating the swollen surface layer with light from a linear light source at a predetermined angle to cure said swollen surface surface layer.

Abstract: A laminated structure composed of (A) a layer comprising a polyester resin, (B) a layer comprising a cured (meth)acrylate polymer containing an epoxy group in the molecule, and (C) a layer comprising a cured organopolysiloxane compound, the layers (A), (B) and (C) being laminated in this sequence. The laminated structure is suitable for use in a safety glass, for example.

Abstract: A laminated structure comprising a polyester film and a polyvinylbutyral sheet which are laminated through an adhesive layer obtained by curing a composition comprising an amino group-containing organosilicon compound of the following formula ##STR1## preferably its hydrolytic condensation product and a diamine of the formulaH.sub.2 N--R--NH.sub.2 (II)All symbols in these formulae are as defined in the specification. The structure is particularly useful in an automobile safety glass.
