    摘要: A surface acoustic wave device (e.g., filter or convolver) is designed to increase an electromechanical coupling factor K2 and is basically configured by a substrate, a buffer layer, a piezoelectric layer and an electrode layer. Herein, the substrate is made of a bulk material (e.g., SrTiO3), which allows growth of a perovskite compound crystal being expressed by a general chemical formula of SrZO3 (where Z denotes an element such as Zr and Sn whose valence is 4). The buffer layer is formed on the substrate and is made of the perovskite compound crystal (e.g., SrZrO3, SrSnO3), which has good lattice matching with KNbO3. The piezoelectric layer is made of a KNbO3 single crystal and is formed on the buffer layer with a thickness of 500 nm or so. The electrode layer is formed on or below the piezoelectric layer. An interdigital transducer consisting of input and output electrodes is formed by patterning using photolithography technique being effected on the electrode layer, which is made of a metal material (e.g., Al). In addition, it is possible to form a temperature stabilization layer between the piezoelectric layer and electrode layer. The temperature stabilization layer is made of a material (SiO2) having a temperature coefficient reverse to a temperature coefficient of the piezoelectric layer so as to ease distortion being caused to occur due to differences in thermal expansion between the piezoelectric layer and electrode layer. Incidentally, the temperature stabilization layer has a prescribed thickness, which is approximately 1000 nm.

    摘要: A drum pad has a knitted material that is strechable and has a top surface to be beaten by a stick and a rear surface opposite to the top surface, a resin member that is strechable and thinner than the knitted material and that is capable of being thermally fused and bonded to the knitted material, and a rubber. The drum pad is formed of a first layer portion, a second layer portion, and a body portion. The first layer portion is formed in a region of the knitted material including the top surface thereof but not including the rear surface. The body portion is formed of the rubber. The second layer portion is formed in a remaining region of the knitted material other than the first layer portion and formed between the body portion and the first layer portion.

    摘要: A microreactor comprises a reaction chamber, into which prescribed materials are introduced, a production chamber, and a channel for connecting the reaction chamber and the production chamber together. A plurality of temperature adjusting devices (e.g., Peltier elements), each of which can be independently controlled in temperature, are arranged at prescribed positions with prescribed distances therebetween on a substrate in proximity to the reaction chamber, the production chamber, or the channel. Herein, the reaction chamber causes reaction of the materials in response to differences of boiling points, differences of state changes, or difference of solubility, thus producing a new substance, which is transmitted from the reaction chamber to the production chamber via the channel while being adequately controlled in temperature.

    摘要: In the production of a hollow FRP article such as a wood type carbon black golf club head, a hollow resin shell is formed via blow molding, heat-resistant fine particles are filled as a filler into the interior of the resin shell, the interior of the resin shell is decompressed to form an inner mold, the inner mold is covered with FRP prepreg including thermoplastic resin to form a prepreg composite, the prepreg composite is heated in a metallic mold under pressure and the fine articles are removed after demolding. A golf club shaft is formed by heating a mandrel, applying thermoplastic resin powder to the mandrel and then winding a lamellar prepreg around the mandrel to thereby form a hollow shaft. A golf club is formed from a head and shaft formed as described above by enlarging the end of the shaft, placing the shaft and the head in a mold and heating the mold under pressure.
