It is an object of the present invention to provide an ultrasonic transducer, which is so configured as to reduce the variations in characteristics, thereby to enable the stabilization of the precision, as well as to enable the improvement of the durability, and the like, a method for manufacturing the ultrasonic transducer, and an ultrasonic flowmeter. In order to attain this object, in accordance with the present invention, the ultrasonic transducer is so configured as to include a piezoelectric element and an acoustic matching layer, wherein the acoustic matching layer is made of a dry gel of an inorganic oxide or an organic polymer, and a solid skeletal part of the dry gel has been rendered hydrophobic. With this configuration, it is possible to obtain the ultrasonic transducer having an acoustic matching layer 3 which is very lightweight and has a small acoustic impedance due to the solid skeletal part of the dry gel which has been rendered hydrophobic. Further, it is also possible to obtain the ultrasonic transducer which shows a narrow range of characteristic variations, and is stable due to the high homogeneity of the dry gel.

A bumper beam assembly for a vehicle comprises a bumper beam having at least two round pipes, a bracket, first and second support members, first and second side frames, and a bracket formed into a rounded shape to match the external shape of the round pipes. The round pipes are arranged vertically and the sum of the diameters of the round pipes is smaller than the height of the bumper beam. The first and second support members have arc-shaped recesses which conform to the external shape of the round pipes and support the round pipes to connect the side frame to the round pipes, and one of the round pipes is positioned below a central point of the first and second side frames, and one of the round pipes is positioned above the central point.

An acoustic matching layer according to the present invention includes a powder of a dry gel. The dry gel preferably has a density of 500 kg/m3 or less and an average pore diameter of 100 nm or less. By using the dry gel powder, a variation in the property of the acoustic matching layer can be reduced.

摘要:
Dirt, particularly of inorganic matter, attached to a substrate, such as a glass substrate for liquid crystal devices, is effectively removed by irradiating the substrate with ultraviolet rays including 184.9 nm and 253.7 nm in an oxygen-containing atmosphere in advance of wet cleaning with pure water. As a result, the wet cleaning time and the amount of pure water can be reduced.

The present specification discloses a compressor characterized in that a nonpolar solvent is used as a working fluid and an insulation part of a rotating section is formed from a low dielectric constant plastic film having a specific dielectric constant of 1.2 to 3.0. This compressor has been reduced in leakage current and improved in safety and reliability, and therefore can realize energy savings for devices such as a refrigerant system device.
摘要:
A composite material having a plurality of laminated polysilylenemethylene layers each having an inside region adjacent to a surface thereof in which nanoparticles of a metal of Au, Pt, Pd, Cu or Ag are dispersed. The composite material is produced by heating a layer of disilacyclobutane overlaid with a layer of nanoparticles of the above metal to polymerize the disilacyclobutane. The above procedure is repeated at least once more.

摘要:
A liquid crystal display device is constituted by a pair of oppositely disposed first and second substrates each having thereon a plurality of transparent stripe-shaped electrodes so that the transparent stripe-shaped electrodes on the first and second substrates intersect each other to form an electrode matrix, each stripe-shaped electrode being provided with a sub-electrode superposed thereon; and a liquid crystal disposed between the first and second substrates so as to provide a plurality of pixels each at an intersection of the stripe-shaped electrodes on the first and second substrates, thereby forming a display region including the pixels and a visible peripheral region surrounding the display region. In the visible peripheral region of the display device, the sub-electrodes on the first and second substrates are extended to mask or light-interrupt the stripe-shaped electrodes and spacings between the stripe-shaped electrodes on the first and second substrates.
