摘要： Titanium is added in the form of atoms, a colloid, or ions to a glass to be subjected to laser processing in which the ablation or vaporization caused by the energy of an absorbed laser light is utilized. Since titanium can be incorporated into the glass through melting, the threshold value for processing can be easily regulated by changing the amount titanium to be added and a material having evenness in processability can be obtained.

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.

摘要： A liquid drop detector which may be fixed or attached by a simple operation, without machining, to a window glass, includes a light emitting element, a light receiving element and light guiding bodies wherein the light emitted by the light emitting element is introduced through a diffraction grating into a first light guiding body and after undergoing total internal reflection within the first light guiding body it is introduced through a silicon member, through an elongated light guiding body, through an additional silicon member, and into a windshield. After traveling within the windshield by total internal reflection, the light passes through a silicon member, reenters the elongated light guiding body, passes through another silicon member and enters a second light guiding body which guides it to a receiver. When rain drops adhere to the outside surface of the windshield at points corresponding to the total internal reflection points at the outer surface of the windshield, the light will leak out of the windshield. As a result of this, the amount of light received by the light receiving element is lessened, thereby providing for detection of the adhesion of rain drops based thereupon so as to output a signal for driving a device such as the windshield wiper.

摘要： The present invention improves a method of forming a surface unevenness using a difference in etching rates, and relaxes limitations on substrates in this method. In a method of the present invention, an uneven surface is formed by a method including applying pressure to a predetermined region in a surface of a thin film formed on a substrate, and etching a region including at least a portion of the predetermined region and at least a portion of the reminder of the surface that excludes the predetermined region. An etching rate difference within the thin film increases freedom in selecting a substrate material.
