摘要： An ultrasonic sensor includes an ultrasonic detecting element, an acoustic matching member, and an oscillation damping member. The ultrasonic detecting element detects an ultrasonic wave. The acoustic matching member has a receiving surface that is adapted on a side of the certain object to be exposed to a space, in which the detected body exists. The receiving surface receives the ultrasonic wave reflected by the detected body. The acoustic matching member is made of a material having an acoustic impedance larger than that of air and smaller than that of the ultrasonic detecting element. The oscillation damping member is disposed between an attachment portion and the acoustic matching member. The attachment portion is adapted for attaching the ultrasonic sensor to the certain object. The oscillation damping member damps transmission of oscillation from the certain object to the acoustic matching member.

摘要： A concentration sensor device includes a sensor unit, a substrate, and a sedimentation limit unit. The sensor unit detects a concentration of a specific component contained in liquid. The substrate has a face to which the sensor unit is arranged. The sedimentation limit unit is integrally arranged with the sensor unit or arranged at an upstream side of the sensor unit in a flowing direction of the liquid. The sedimentation limit unit is configured to prevent sedimentation of a foreign object on the sensor unit. The sedimentation limit unit includes a piezoelectric element to vibrate when electricity is supplied so as to promote the foreign object to be separated from the sensor unit. The substrate has a recess recessed in a thickness direction of the substrate.

摘要： A detector device of the present invention detects densities of components, such as gasoline and ethanol, contained in mixture fuel even when some water is included in the mixture fuel. The detector device includes a sensor having a pair or electrodes, an electronic device for calculating the densities and a memory device for storing permittivities of pure components including water measured beforehand. Alternating current having two different frequencies f1, f2 is applied to the pair of electrodes immersed in the mixture fuel to detect the permittivities of the mixture fuel under f1 and f2. The two frequencies, f1 and f2, are so chosen that the premittivities of gasoline and ethanol show no change between f1 and f2, while the permittivitiy of water shows a substantial difference between f1 and f2. The electronic device calculates the densities of the components based on permittivities of the mixture fuel detected by the sensor and those of components stored in the memory device.

摘要： A fluid sensor detects property of fluid by dipping the sensor in the fluid. The sensor includes: a semiconductor substrate; and a comb-teeth electrode made of a first diffusion layer and disposed on a first surface of the substrate. Although the comb-teeth electrode is capable of directly contacting the fluid without a protection film, corrosion resistance of the sensor against the fluid is improved. Further, since the sensor has no protection film, the sensor can detect the property accurately.

摘要： A semiconductor device includes a molding resin layer and a semiconductor element encapsulated with the molding resin layer. The molding resin layer has an opening. A surface of the semiconductor element is partially exposed outside the molding resin layer through the opening. A groove is located in the surface of the semiconductor element around the opening of the molding resin layer. The groove is filled with the molding resin layer to produce anchor effect that enhances adhesive force of the molding resin layer to the surface of the semiconductor element around the opening.
