Abstract

This rod lens array 10a comprises a plurality of refractive index distribution-type rod lenses 1b arranged such that optical axes thereof are parallel to each other, and forms an erecting equal magnification image. A refractive index distribution-type rod lens 1b has a refractive index distribution in a radial direction. The radius of the refractive index distribution-type rod lens 1b is represented by r0. The central refractive index, which is the central refractive index of the refractive index distribution-type rod lens 1b, is represented by no. The refractive index distribution constant of the refractive index distribution-type rod lens 1b is represented by vA. The refractive index at a distance r from the center of the refractive index distribution-type rod lens 1b is approximated as n(r) = n0 ? {1 - (A/2) ? r2}. The opening angle ? represented by sin-1 (n0 ? vA ? r0) is 3 to 6°. The imaging distance of the rod lens array 10a is 45 to 75 mm. The depth of field, in which the value of a modulation transfer function (MTF) at a spatial frequency of 6 lines/mm is 30% or more, is 1.5 to 3.0 mm.

Abstract

A greenhouse according to the present invention is provided with a ceiling part and a coating-film-attached glass plate which is arranged at at least a part of the ceiling part. The coating-film-attached glass plate has a total light transmittance of 90% to 98%, a haze rate of 20% to 80%, and a hemispherical transmittance of 80% to 90%. When a test is carried out in accordance with JIS R 1703-1:2007 in which oleic acid is applied onto a surface of a coating film and is then irradiated with ultraviolet ray having an intensity of 1.0 mW/cm2, the time from the start of the irradiation with ultraviolet ray to the time at which the water contact angle on the surface becomes 5° is 24 hours or less.

Abstract

A vehicular glass module (1) that includes vehicular window glass (2) on which a conductive pattern (4) is formed and an on-glass connector (3) that is attached to the vehicular window glass (2). The on-glass connector (3) has a hollow part (11) and a circuit board (6) that is arranged inside the hollow part (11). The hollow part (11) communicates with the outside of a case (5) via a through hole (15) that is provided in a partition wall (14) that defines a portion of the hollow part (11). The through hole (15) is positioned below the circuit board (6). Water that condenses inside the hollow part (11) is discharged to the outside via the through hole (15).

Abstract

A reinforcing cord for rubber reinforcement of the present invention that is used for reinforcing a rubber product is provided with a plurality of strands. The strand includes bundled fibers and a coating layer formed so as to cover the bundled fibers. The plurality of strands are in tight contact with one another via the coating layer. The coating layer contains a material that is crosslinkable by thermal treatment. A method of manufacturing the reinforcing cord for rubber reinforcement includes the steps of (i) forming strands that include bundled fibers and a coating layer formed so as to cover the bundled fibers, and (ii) bringing the strands into tight contact with one another via the coating layer by twisting the strands together. The coating layer contains a material that is crosslinkable by thermal treatment.
