A reinforcing cord of the present invention is a reinforcing cord (10) for rubber reinforcement including a fiber core (11) and a plurality of strands (12) disposed around the fiber core (11). The fiber core (11) is formed of one or a plurality of highly elastic fibers having a tensile elastic modulus of at least 100 GPa. Each of the plurality of strands (12) is formed of a plurality of glass fibers that are primarily twisted, and the plurality of strands (12) are finally twisted to be disposed around the fiber core (11). The direction of the final twist of the plurality of strands is opposite to the direction of the primary twist in each of the plurality of strands (12). The number of final twists of the plurality of strands (12) is 1.0 to 3.0 times/25 mm, and a ratio of the number of primary twists in each of the plurality of strands (12) to the number of final twists of the plurality of strands (12) (the number of primary twists/the number of final twists) is in a range of 1.5 to 2.5.

The present invention provides a heat-reflecting windshield that includes a laminated glass sheet and a detecting device for optically detecting a target object such as water droplets. The laminated glass sheet includes a first glass sheet, a heat-reflecting film formed on the first glass sheet, an intermediate film and a second glass sheet. The detecting device is disposed on a main surface of the laminated glass such that a light-emitting element and a light-receiving element in the device are arranged in a predetermined region of the main surface, and the predetermined region is rubbed by a windshield wiper. The heat-reflecting film includes at least three dielectric layers and at least two metal layers, and the heat-reflecting film is not formed in said predetermined region.

摘要:
The present invention provides an object-sensing device capable of estimating the presence of an object attached on a sensing surface, the kind of the object and the state of the object. An image is formed by a lens with light via the sensing surface, and the light is received by a light-receiving element portion in which a plurality of micro-light-receiving elements are arranged. In the object detection mode, totally reflected light from the sensing surface is received by the light-receiving element portion. The components are arranged at an angle that allows total reflection when there is no object, and does not allow the total reflection condition to be satisfied when there is an object. In the light scattering object detection mode, scattered light from the sensing surface is received by the light-receiving element portion. A signal pattern is obtained by joining detection signal levels of the micro-light-receiving elements in accordance with the arrangement of the micro-light-receiving elements. An increase portion or a drop portion of the signal pattern that appears in accordance with the presence of the object or a difference in the state thereof is analyzed, so that the kind and the state of the object such as a rain drop, muddy water, fogging, ice or the like are estimated.
