  • Patent number: 7250706
    Abstract: The present invention achieves the wideband operation of a bolted Langevin-type echo sounder transducer by enabling low frequency operation with securing a sound pressure level above a certain level without changing the external dimensions of the echo sounder transducer. This is an echo sounder transducer includes a Langevin-type vibrator having a front mass and a rear mass, and a cylindrical active vibrator which is sandwiched between the front mass and rear mass, a bend vibrator constituted of a diaphragm arranged in an acoustic radiation surface section of the front mass of the Langevin-type vibrator, and a disc type active vibrator fixed to the diaphragm. This has such structure that a slit, communicating from an outer peripheral side face toward an axial center, is provided on the circumference in the side of the lower portion of the front mass of the Langevin-type vibrator toward the rear mass.

  • Patent number: 7209696
    Abstract: An image heating apparatus includes a rotation made of a metal, a heater to which a current is applied, whereby heat dissipates from the heater and the heater contacts an internal surface of the rotation member, and a pressure roller for pressurizing the rotation member together with the heater to form a nip, wherein the rotation member is electrically grounded via a fuse. By the virtue of the invention, it is rendered possible to suppress charging of the metal rotation member and to suppress a current leak to a main frame of an image forming apparatus.

  • Patent number: 7187105
    Abstract: A transducer includes a Langevin type vibrator, a bending vibrator, and a ring-like member. The Langevin type vibrator has a construction in which a front mass, a cylindrical vibrator, and a rear mass are provided in tandem, and those elements are tightened by a bolt. The bending vibrator is provided apart from the front mass. The ring-like member is provided in outer peripheral portions of the front mass and the bending vibrator to couple the front mass and the bending vibrator to each other. The transducer generates a large sound pressure over a wide frequency band since a sound wave radiation surface is wide and its amplitude amount is large.
