    Abstract: A mechanical deformation amount sensor includes a sensor structure which is formed by a semiconductor substrate or an insulating substrate. The sensor integrally includes a deformation portion deformable when a physical quantity to be detected is applied to the sensor structure. The sensor also includes a support portion for supporting the deformation portion, a carbon nanotube resistance element disposed on the deformation portion so as to be mechanically deformed in response to deformation of the deformation portion and a wiring pattern which is formed in a pattern on the sensor structure so as to be connected to the carbon nanotube resistance element. By applying a voltage to the carbon nanotube resistance element via the wiring pattern, a change of electrical conductivity of the carbon nanotube resistance element upon mechanical deformation of the carbon nanotube resistance element is transduced in an electrical signal.

    Abstract: A photoelectric smoke detector has a circuit substrate coupled to an optical-system base as disposed in a circuit accommodating zone defined within a detector housing by the base together with a smoke supervisory zone, a light projecting element and an integrated circuit incorporating therein a light receiving element and smoke detecting means are mounted to the circuit substrate, and the optical-system base holds therein a light receiving lens which is capable of condensing scattered light from smoke particles onto the light receiving element in the integrated circuit on the circuit substrate. Effective reduction in the number of constituent parts is thereby attained, to promote reduction in manufacturing costs, and to effectively realize dimensional minimization.

    Abstract: A photoelectric smoke detector has a circuit substrate 17 coupled to an optical-system base 14 in a circuit accommodating zone 16 defined within a detector housing 10 by the base together with a smoke supervisory zone 15. A light projecting element 22 and an integrated circuit 18 incorporating therein a light receiving element and smoke detecting means are mounted to the circuit substrate, and the optical-system base holds therein a light receiving lens 25 in the form of a prism section 26 integral with a lens section 27 which is capable of condensing scattered light from smoke particles onto the light receiving element in the integrated circuit on the circuit substrate. Effective reduction in the number of constituent parts is thereby attained, to promote reduction in manufacturing costs, and to effectively realize dimensional minimization.
