摘要： In homogeneous materials, etching characteristics depend on properties inherent in these materials regardless of whether they are isotropic or anisotropic, and there have been limitations in realizing various desired shapes. A subject for the invention is to provide a gradient material which eliminates these limitations. A gradient material is provided in which the rate of etching with a specific chemical substance changes continuously or by steps from the outermost surface to an inner part thereof. This gradient material is made of a main material which contains an additive capable of changing the etching rate of the main material so that the concentration of the additive changes continuously or by steps. Especially when a glass material containing SiO2 as the main component is used as the main material and fluorine is used as the additive, then a gradient material in which the rate of etching with an aqueous solution of hydrofluoric acid changes in the depth direction can be obtained.

摘要： In the present invention, a surface 7 of a glass substrate 1 is irradiated with a laser beam 2 to thereby form a V-shaped groove 6. At that time, the laser beam 2 is condensed outside and above the glass substrate 1. The distance between a beam-condensing point 4 of the laser beam 2 and the surface 7 of the glass substrate 1 is changed to thereby make it possible to change the angle between opposite side surfaces of the V-shaped groove. The angle is in a range of from 30 degrees to 120 degrees. Further, the laser beam used in the present invention is pulsed light, preferably with a pulse width not larger than 10 picoseconds.

摘要： In a method for detecting liquid drops adhering upon a front windshield with superior sensitivity but without obstructing drivers, a light beam emitted from a light emitting element 4 is guided into a light guiding body 7, and after undergoing total internal reflection within light guiding body 7, it is guided into a front windshield G. The light guided into the front windshield G is received by a light receiving element 5 after repeated total internal reflections within the front windshield G. In this instance, when raindrops adhere on the outside surface of the front windshield G and the adhering points are at the total internal reflection points of the light mentioned above, then the light beam guided into the front windshield G passes through and goes out from the windshield G without undergoing total internal reflection therein. As the result of this, the amount of the light beam received by the light receiving element decreases, thereby enabling detection of adhesion of raindrops based thereon, so as to output a signal for driving a wiper equipment or the like.

摘要： A sheet of silicate glass having a thickness of 2 mm and composed mainly of SiO2, and containing Al2O3, B2O3, Na2O, F, etc., is immersed in a molten salt comprising a mixture of 50 mol % of silver nitrate and 50 mol % of sodium nitrate. Na ions in the surface of the glass are eluted, diffusing Ag ions in the molten salt into the glass. When a laser beam is applied to the glass substrate thus formed, the glass substrate is evaporated or ablated progressively from its surface. The glass substrate is processed to a smooth finish without causing cracking or breakage.

摘要： In a method for forming a hole for fitting an optical fiber only at a core portion without having to precisely match or accord the focus of a laser beam with the end surface of an optical waveguide, when a laser beam is irradiated onto the end surface of the optical waveguide, the focus of the laser beam is turned away from the end surface of the optical waveguide and a region of the irradiation includes the core and the periphery thereof. Thereafter, the energy of the laser beam is increased step by step, and a few pulses thereof are radiated with the intensity fixed when ablation occurs at the core portion, so that the hole is formed only at the core portion.
