  • Publication number: 20190307503
    Abstract: An energy treatment device includes a movable handle including a jaw and a first through hole, an elongated member, and a sheath including a hollow portion and a second through hole, wherein the hollow portion is configured to receive the elongated member.

  • Patent number: 7791821
    Abstract: A lens drive apparatus includes: a base member; a holder having a cylindrical shape and movably supported in an optical axis direction relative to the base member; a cam member and moving the holder in the optical axis direction by abutting with the holder; and a biasing member urging the holder such that the holder 40 comes into contact with the cam member 50. The holder is formed such that a lens frame holding a lens is inserted and assembled into the holder from one side of the holder to another side of the holder. The cam member is disposed close to the one side with respect to the holder.

  • Patent number: 6510544
    Abstract: The wiring design software 3 reads in design information, analyzes it to generate a wiring problem and correlates bonding pads and pins of a semiconductor package to each other (S102, S104). The wiring design software 3 then searches a wiring route while permitting crossing by using the Dijkstra method and the like, calculates an evaluation value by weighting the length of a candidate route with a coefficient W when the candidate route crosses a monitoring side E, and selects a candidate route having a minimum evaluation value as a partial route (S110).

  • Patent number: 5332950
    Abstract: A driver circuit for a display device, in which first and second clock pulse generator circuits generate first and second clock pulses to a gate circuit for allowing the first clock pulse to pass when the first and second clock pulses are a high level, and by the output of the gate circuit, a combination of a transistor and an inductance generate a high voltage pulse. The high voltage pulse is rectified in a triple voltage rectifying circuit to output a high voltage output for driving the display device such as EL elements, and the high voltage output can be reset by a low frequency pulse output from a discharge circuit. As a result, no inverter is required, and a small-sized and light-weighted driver circuit is achieved with a long luminescence life of the EL elements and without noises offensive to the ear.

  • Patent number: 4868816
    Abstract: A polling communication method which asks whether or not there is a request with data from a range of answer requesting terminals. A request is determined by a binary looking-up to terminals by a center. The center and the terminals are connected through a common signal transmission line, replying to the center that there is a request with a self-address to the requesting terminal. There is a further reducing of the range of answer requesting terminals by sequentially determining, according to a binary looking-up to specify one of the requesting terminals when a collision of the requests occurs between the terminals at the replying time. The center then asks the content of the request to the specified terminal. Thus, this method can process requests at a high speed, not only when the rate of requests of terminals is low but also when the rate of requests of terminals is high and often collide.
