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： A glass substrate having fine holes formed therein by use of a laser beam without cracks or fragmentation occurring. A glass substrate is used in which silver is contained in the form Ag atoms, Ag colloid or Ag ions, to a predetermined depth from a surface of the glass, and further the concentration gradient of the silver is a maximum at one side surface on which the fine hole machining is performed and gradually decreases toward the other side surface, whereby ablation and evaporation occurs from the surface having the maximum concentration of silver layer by layer without causing cracking or fragmentation.

摘要： An object sensor is provided, which has a high object detection rate with respect to an object such as a raindrop adhering to a detection surface, and which is capable of detecting the presence/absence of an object with a high sensitivity. A light source 10, a detection surface 110, a focusing lens 40, and a plurality of photodetecting elements of a photodetecting unit 50 form a focusing system of equal magnification that is capable of catching an image in a size smaller than an object to be detected. Light emitted from the light source 10 is incident on the detection surface 110 via a prism 20 at a predetermined incident angle. Without a raindrop 120, the total internal reflection condition is satisfied as shown by a path 140 of a beam, so that the beam is subjected to the total internal reflection. Then, the beam passes through a prism 30, and is focused on a photodetecting surface of the photodetecting unit 50 by the focusing lens 40. On the other hand, with a raindrop 120, the total internal reflection condition is not satisfied as shown by a trail 130 of a beam, so that the beam passes therethrough and is not focused on the photodetecting unit 50. A difference in signal level is determined on the photodetecting element basis, so that an object covering the detection surface 110 is detected.
