  • Patent number: 11113297
    Abstract: A website server provides a program for a web page of a predetermined website to a user terminal. The program for the web page causes the user terminal to implement a display module and a search module. The display module causes a first article selected by a user to be displayed and causes a search window to be displayed at a position after a position where the first article ends. The search module searches for a second article related to a character string entered in the search window. The display module causes information related to the second article identified by a search using the search module to be displayed near the search window.

  • Patent number: 7679474
    Abstract: A surface acoustic wave resonator has a piezoelectric substrate (11), an IDT (13) formed of a plurality of electrode fingers (12) disposed on piezoelectric substrate (11), and reflectors (14) disposed near the opposite ends of IDT (13). The IDT (13) has a gradation region where the electrode finger pitch of the plurality of electrode fingers (12) at the opposite ends is different from the electrode finger pitch near the center of the IDT (13). In this gradation region, the electrode finger pitches are sequentially varied in the range from the electrode finger at the farthest end that is one end of the gradation region to the electrode finger lying at the other end of the gradation region. The electrode finger pitch of the electrode fingers at the farthest end that is one end of the gradation region is set to be 1 through 5% smaller than the electrode finger pitch near the center of the IDT (13).

  • Patent number: 6972509
    Abstract: A surface acoustic wave (SAW) device includes a piezoelectric substrate, and on this substrate there are provided comb electrodes for forming an inter digital transducer (IDT), reflector electrodes placed closely along a traveling direction of a surface wave generated by the IDT, and a frame-like short-circuited auxiliary electrode having a width varying depending on its portions. This structure allows to uniform electric charges overall the electrode-surfaces, where the electric charges are generated in a heat treatment applied to the piezoelectric substrate during the manufacturing of the SAW device. Thus even after the device is diced into pieces, this structure can prevent damages of the electrodes or degradation in electrical properties due to an electric discharge generated by accumulated electric charges caused by pyroelectricity of the substrate.
