摘要： A directional sound apparatus includes a planar shape plate and a sound wave generator. The planar shape plate has a plurality of grooves formed on a surface of the planar shape plate. The sound wave generator is configured to radiate a sound wave to outside from the surface of the planar shape plate. A width of each of the grooves and a distance between the grooves adjacent to each other are smaller than a wavelength of the sound wave. The planar shape plate has a plurality of cell areas in which at least one groove is included. A structure of the groove included in a first cell area is different from that of the groove included in a second cell area adjacent to the first cell area, so that surface admittance in the first cell area is different from that in the second cell area.

摘要： A liquid resin in which conductive particles are dispersed is supplied to between a circuit substrate and a semiconductor chip disposed so as to face each other and an ultrasonic wave having an amplitude in a perpendicular direction to a surface of the circuit substrate to generate a standing wave in a resin. Then, the conductive particles dispersed in the resin are captured at nodes of the standing wave to form connection bodies of aggregation of the conductive particles between connection terminals of the semiconductor chip and terminals of the circuit substrate. Thus, the semiconductor chip is mounted on the circuit substrate via the connection bodies. The terminals are arrayed so as to be spaced apart from one another by half a wavelength of the standing wave and each of the nodes of the standing wave are generated at a position between the terminals in the resin.

摘要： An ultrasonic structure which has a thin planar sheet of material forming a Lamb wave propagation medium The propagation medium is coated with a gel. The structure may also include a Lamb wave generator for generating Lamb waves in the propagation medium and an output device for producing an electrical signal representative of the propagation characteristics of the Lamb waves propagating along the propagation medium. A measuring device can be included to measure selected characteristics of the output electrical signal. The propagation medium has some physical characteristics that are determined by the value of a measurand acting on the medium and the determined physical characteristics determine the propagation characteristics of the Lamb waves which are propagated along the medium. When the sensor is acted on by a measurand to determine the physical characteristics of the propagation medium, the characteristics of the electrical signal are also determined. The measuring device measures the electrical signal and provides an indication of the measurand value.

摘要： An apparatus is featured for controlling remote devices. The status or one or more switches associated with remote devices may be transmitted along a single transmission line. One end of the transmission line contains a surface acoustical wave (SAW) delay line. The SAW delay line responds to an interrogation pulse of radio frequency electromagnetic energy with a series of delayed pulses, each of which transmits the status of a switch by means of the presence or absence of the pulse. The SAW delay line and switches are completely passive, requiring no power source. The transmission line may optionally be interrupted and coupled by means of a pair of inductive coils. This offers the potential for rotation, as within a steering column of an automobile, without wear or damage to the transmission line. The other end of the transmission line contains electronic circuitry to provide the interrogation pulse, to decode the return delayed pulses, and to drive other circuitry as required by the switch positions.

In one embodiment, signal leads extend beneath the substrate to areas adjacent the rear portions of the comb structures and are capacitively coupled thereto via the substrate which is a dielectric. In another embodiment, inductive coupling loops interconnect the rear portions of the comb structures of a respective transducer and another inductive loop is carried on the opposite side of the substrate for signal coupling. In both embodiments both symmetrical and asymmetrical signal coupling is provided by utilizing a grounding plate or layer as a signal lead.
