  • Publication number: 20250030403
    Abstract: A filter device includes a first signal terminal, a second signal terminal, and a plurality of resonators including a plurality of series arm resonators and a plurality of parallel arm resonators. At least one of the plurality of series arm resonators and the plurality of parallel arm resonators is an excitation angle change resonator. The excitation angle change resonator includes a piezoelectric substrate including a piezoelectric body layer, and an IDT electrode including a plurality of electrode fingers provided on the piezoelectric substrate. The piezoelectric body layer has a propagation axis. The plurality of electrode fingers are curved. An excitation direction of an acoustic wave in a portion of an electrode finger in the plurality of electrode fingers is one of first to third directions.

  • Patent number: 8346797
    Abstract: A search device and an information providing system are structured, to lessen a user's operation load, such that a crawling portion executes a crawling while sequentially changing an expansion header indicating a voice display capacity in an HTTP request into a voice display capacity of a typical model within each of model groups, and registers the obtained result in a search index in correspondence to the model name within the model group, a search service providing portion executes a search from the search index in correspondence to a search condition like a key word from a cellular phone terminal unit and the model name in the HTTP request, and a response portion generates a search result in correspondence to a template, and sends to a Web browser of the cellular phone terminal unit via an HTTP server.

  • Patent number: 5126128
    Abstract: Periplanone-B analogue of (4E, 8R, 9R, 10R)-8,9-epoxy-5-methyl-10,10-methylene-oxy-4-cyclodecen-1-one, suitable as cockroach attractant can be prepared by reacting 6-methyl-2,6-cyclodecadien-1-one with a silylating reagent under the presence of a basic catalyst to form a silyldienol ether, reacting the resultant ether with an organic peracid to obtain (2Z, 6E)-10-hydroxy-6-methyl-2,6-cyclodecadien-1-one, reacting the resultant product with a peroxide under the presence of a basic catalyst after protecting hydroxy groups thereof with protection groups to obtain an epoxide, reacting the epoxide with chloromethyl lithium or dimethyl sulfonium methylide thereby introducing a spiroepoxy group and then removing the protection groups, to obtain (1S, 4E, 8R, 9R, 10S)-8,9-epoxy-5-methyl-10,10-methyleneoxy-4-cyclodecen-1-ol and, further, oxidizing the resultant product with a chromic acid type or dimethyl sulfoxide type oxidizing agents.

  • Patent number: 4893199
    Abstract: A digital recording apparatus for recording signals received by means of a digital interface format composed of a category code, specifying a device on the transmission side, digital main data, and digital subdata for control, includes means for judging the category code of the received data. When the judged category code is different from the category code of a recording apparatus, means are provided for converting the digital subdata into the necessary digital subcode data for the recording apparatus and the data is thereafter recorded.
