摘要： A fire alarm system, determining existence or nonexistence of a fire by using an ultrasound wave, comprises a sound wave generator and a sound wave detector to detect sound waves propagated through two propagation paths having different lengths each other. The system comprises a calculation means for calculating a pressure ratio between a first sound pressure, which is a sound pressure of a sound wave propagated through a first propagation path, and a second sound pressure, which is a sound pressure of a sound wave propagated through a second propagation path, and a smoke density estimator. The smoke density estimator calculates a change ratio between the pressure ratio calculated by the calculation means and a predetermined standard pressure ratio, and determines a smoke density from the change ratio based on a predetermined relational expression describing the relation between the change ratio and the smoke density, and determines existence of a fire when the smoke density exceeds a predetermined threshold.

摘要： A semiconductor substrate is anodized to be shaped into an optical lens. Prior to being anodized, the substrate is finished with an anode pattern on its bottom surface so as to be consolidated into a unitary structure in which the anode pattern is precisely reproduced on the substrate. The anodization utilizes an electrolytic solution which etches out oxidized portion as soon as it is formed as a result of the anodization, to thereby develop a porous layer in a pattern in match with the anode pattern. The anode pattern brings about an in-plane distribution of varying electric field intensity by which the porous layer develops into a shape complementary to a desired lens profile. Upon completion of the anodization, the semiconductor substrate is shaped into the lens by etching out the porous layer and the anode pattern from the substrate.

摘要： An infrared detection unit includes a base carrying an infrared sensor element, and a cap configured to be fitted on the base to surround the infrared sensor element. The cap has a top wall with a window in which a semiconductor lens is fitted to collect an infrared radiation onto the infrared sensor element. The semiconductor optical lens is formed from a semiconductor substrate to have a convex lens and a flange which surround said convex lens. An infrared barrier is formed on the semiconductor lens to block the infrared radiation from passing through the boundary between the circumference of the convex lens and the window. Accordingly, the infrared sensor element can receive only the infrared radiation originating from a detection area intended by the convex lens.
