  • Patent number: 7418102
    Abstract: An echo sounder includes front and rear masses and a layered product of piezoelectric ceramics sandwiched therebetween, and a hollow space is formed in the front mass for defining a bending vibratory plate portion; a ring-shaped piezoelectric vibrator is accommodated in the hollow space, and has flat major surface or an outer side surface held in contact with the front mass without being fixed to the bending vibratory plate; while the layered product of piezoelectric ceramics gives rise to bending vibrations in the bending vibratory plate, the ring-shaped piezoelectric vibrator is driven for vibrations at the resonant frequency so that an acoustic wave with a large amplitude is radiated from the echo sounder; the bending vibratory plate and ring-shaped piezoelectric vibrator are independently designed so that the echo sounder achieves a high acoustic radiation efficiency without sacrifice of high withstand water pressure.

  • Patent number: 7061544
    Abstract: A digital television receiver includes a CS receive circuit (12). This CS receive circuit receives a digital television broadcast signal. The digital television broadcast signal contains video data from which first video data is created as well as EPG data from which second video data is created. First and second video compression circuits (18, 20) respectively compress first and second video data and output first and second compression video signals. The first and second compression video signals are composited together by a video compositing circuit (22). Consequently, on the monitor (24) are displayed EPG and broadcast video picture in a 2-screens form.

  • Patent number: 6731346
    Abstract: A television including a CS digital circuit to receive a CS digital television broadcast signal. A micom circuit detects a broadcast mode of the digital television broadcast. Where the broadcast mode is in a first mode, or usual broadcast mode, the power supply to a video output section and audio output section, for example, is turned on to output video images and sound respectively through a CRT and a speaker. Also, where the broadcast mode is in a second mode, or radio broadcast mode, the power supply to the video output section is turned off. Where the broadcast mode is in a third mode, or data broadcast mode, the power supply to both the image output section and the audio output section is turned off.

  • Patent number: 5470374
    Abstract: The present invention is directed to a method for a continuous mass-production, on an industrial scale at a high efficiency, of magnetic metal particles having excellent magnetic properties by preventing particle deformation and mutual sintering of the particles in a reduction process, and/or by preventing deterioration of the magnetic properties and unevenness in the properties, particularly in the saturation magnetization, upon oxidation in a stabilization process. In this method, an iron compound based on iron oxyhydroxide can be thermally dehydrated in a thermal dehydration process. These processes can be conducted using apparatuses of the present invention which have a gas flow reactor; a belt conveyor being installed in the reactor and having a gass-passable belt for transporting the material; a gas dispersion plate; and a heating means.
