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： In an acoustic wave sensor for detecting a distance to an object and an orientation where the object is located with using acoustic waves, an acoustic wave generating device generating an acoustic wave by applying thermal impact to the air with no mechanical vibration is used as a wave transmitting device, and an electric capacitance microphone converting variation of pressure due to acoustic wave to variation of an electric signal is used as each wave receiving device. Therefore, dead zone caused by reverberation component included in the acoustic wave transmitted from the wave transmitting device and dead zone caused by reverberation component included in wave receiving signals outputted from the wave receiving devices can be shortened and angular sensitivity of the acoustic wave sensor can be increased, in comparison with a conventional acoustic wave sensor using piezoelectric devices as the wave transmitting device and the wave receiving devices.

摘要： A field emission type electron source 10 is provided with an n-type silicon substrate 1, a strong field drift layer 6 formed on the n-type silicon substrate 1 directly or inserting a polycrystalline silicon layer 3 therebetween, and an electrically conductive thin film 7, which is a thin gold film, formed on the strong field drift layer 6. Further, an ohmic electrode 2 is provided on the back surface of the n-type silicon substrate 1. Hereupon, electrons, which are injected from the n-type silicon substrate 1 into the strong field drift layer 6, drift in the strong field drift layer 6 toward the surface of the layer, and then pass through the electrically conductive thin film 7 to be emitted outward. The strong field drift layer 6 is formed by making the polycrystalline silicon 3 formed on the n-type silicon substrate 1 porous by means of an anodic oxidation, and further oxidizing it using dilute nitric acid or the like.
