  • Patent number: 7804380
    Abstract: An acoustic wave duplexer has a satisfactory isolation characteristic between a reception acoustic wave filter chip and a transmission acoustic wave filter chip, and includes a reception surface acoustic wave filter chip and a transmission surface acoustic wave filter chip mounted on a substrate. The substrate includes first and second balanced terminals and a common terminal. At least one of the transmission surface acoustic wave filter chip and the reception surface acoustic wave filter chip is a balanced filter unit that includes, as an input terminal or an output terminal, a first balanced signal terminal and a second balanced signal terminal. The acoustic wave duplexer further includes a first interconnection arranged to connect the balanced filter unit and the first balanced terminal and a second interconnection arranged to connect the balanced filter unit and the second balanced terminal. The first and second interconnections intersect with each other while being insulated from each other.

  • Patent number: 5866833
    Abstract: Automatic play progresses automatically with each sound generating operation based on timing data that indicates the timing for sounding a tone. In this manner, performance information for time count automatic play can be used with one-step automatic play. In addition, the information based on the tone generation operation for one-step automatic play and the information based on the sound generating operation for manual play are assigned to tone generating channels, which enables one-step automatic play and manual play to be performed together (in soli). Also, whether or not one-step automatic play is performed can be selected for each respective performance part or instrumental part.

  • Patent number: 5760591
    Abstract: A method of and an apparatus for determining an electric wiring state, having the steps of: feeding at least one pulse voltage signal into one of two lines short-circuited at their two source portions; detecting the pulse voltage signal at two end portions corresponding to the two source portions; and discriminating wiring state between the two source portions and the corresponding two end portions upon a comparison of polarities between the fed pulse voltage signal and the detected signal.

  • Patent number: 5247514
    Abstract: A multiple channel transit call control apparatus includes a transit message storage queue unit, a node message counter, a node transit trunk call opportunity message definition count memory, and a control unit. The transit message storage queue unit stores transit messages arriving at a storage and forward switching system according to destination node identity. The node message counter counts messages in the transit message storage queue unit according to destination node identity. The node transit trunk call opportunity message definition count memory defines the number of channels to be called for every predetermined count of the node message counter according to destination node identity. The control unit outputs a call request signal when the value of the node message counter exceeds a predetermined count stored in the node transit trunk: call opportunity message definition count memory.
