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 field emission-type electron source 10 includes an insulative substrate 11 in the form of a glass substrate having an electroconductive layer 8 formed thereon. A strong electrical field drift layer 6 in the form of an oxidized porous polycrystalline silicon layer is formed over the electroconductive layer 8. This electroconductive layer 8 includes a lower electroconductive film 8a, made of copper and formed on the insulative substrate 11, and an upper electroconductive film 8b made of aluminum and formed over the electroconductive film 8a. The strong electrical field drift layer 6 is formed by forming a polycrystalline silicon layer on the electroconductive layer 8, rendering the polycrystalline silicon layer to be porous and finally oxidizing it. The upper electroconductive film 8b has a property that reacts easily with silicon and, therefore, formation of an amorphous layer which would occur during formation of the polycrystalline silicon layer can be suppressed.

摘要： In a field emission-type electron source (10), lower electrodes (8) made of an electroconductive layer, a strong field drift layer (6) including drift portions (6a) made of an oxidized or nitrided porous semiconductor, and surface electrodes (7) made of a metal layer are provided on an upper side of a dielectric substrate (11) made of glass. When voltage is applied to cause the surface electrodes (7) to be anodic with respect to the lower electrodes (8), electrons injected from the lower electrodes (8) to the strong field drift layer (6) are led to drift through the strong field drift layer (6) and are emitted outside through the surface electrodes (7). A pn-junction semiconductor layer composed of an n-layer (21) and a p-layer (22) is provided between the lower electrode (8) and the strong field drift layer (6) to prevent a leakage current from flowing to the surface electrode (7) from the lower electrode (8), thereby reducing amount of power consumption.

The process for, forming the surface electrode (7) includes the steps of forming a first layer composed of Cr on the drift layer (6), forming a second layer composed of Au on the first layer, and alloying the two layers. The surface electrode (7) has higher adhesion for the drift layer 6 and/or stability for the lapse of time. In addition, the surface electrode (7) has lower density of states in an energy region near energy of emitted electrons, in comparison with the simple substance of Cr. In the surface electrode (7), scattering of the electrons is less so that electron emitting efficiency is higher.

摘要： A pressure wave generator is provided, which has excellent output stability over time. This pressure wave generator comprises a substrate, a heat generating layer, and a heat insulating layer formed between the substrate and the heat generating layer. A pressure wave is generated in a surrounding medium (air) by a change in temperature of the heat generating layer, which is caused upon energization of the heat generating layer. The heat insulating layer comprises a porous layer and a barrier layer formed between the porous layer and the heat generating layer to prevent diffusion of reactive substances such as oxygen and moisture in the air and impurities into the porous layer. By the formation of the barrier layer, it is possible to prevent a reduction in output of the pressure wave generator caused by a change over time of the porous layer.

摘要： Even when compression stress is generated because a volume of a thermal insulation layer 2 is expanded due to oxidized by oxygen in the air, occurrence of cracks and fractures of the thermal insulation layer and a heating conductor 3 caused by the cracks are prevented by dispersing the compression stress. A pressure wave generator comprises a substrate 1, the thermal insulation layer 2 of porous material which is formed on a surface of the substrate 1 in thickness direction, and the heating conductor 3 of thin film formed on the thermal insulation layer 2, and generates pressure waves by heat exchange between the heating conductor 3 and a medium. When a thickness at the center of the thermal insulation layer 2 in width direction W is used as a reference thickness, and it is assumed that distribution of thickness of thermal insulation layer in the width direction is averaged with the reference thickness, porosity in an outer peripheral portion of the thermal insulation layer is made smaller than porosity in the center portion. By making the porosity in the outer peripheral portion of the thermal insulation layer 2 smaller, a number of immovable points on the outer periphery of the thermal insulation layer 2 restricted by the substrate 1 is increased and the positions of them are dispersed, so that the compression stress compressed in the outer peripheral portion of the thermal insulation layer 2 can be dispersed.
