  • Patent number: 9910754
    Abstract: A duplexed control system comprises: two control devices, whereof one is set to operate as a reserve system and the other is set to operate as a regular system; a tracking bus that connects the two control devices to enable these to exchange tracking signals; and a control transmission channel that transmits computational information of these two control devices; wherein: the control devices respectively have: an own-system state evaluation section that transmits the result of state evaluation of its own system as a tracking signal through the tracking bus to the other system; an other-system signal confirmation section that receives the tracking signal through the tracking bus from the control device of the other system and thus performs state confirmation; and a transmission channel changeover section that, if the tracking signal cannot be received through the tracking bus, effects transmission of the tracking signal to the other-system signal confirmation section of the other system, through the control tr

  • Patent number: 8041069
    Abstract: A high efficiency loudspeaker without a damper is provided. The loudspeaker includes magnetic circuit having a magnetic gap and a voice coil member, which has movable coil, disposed in the magnetic gap of the magnetic circuit. The loudspeaker also includes a diaphragm, whose inner peripheral part is linked with the voice coil member, outside the magnetic gap and a frame linked with an outer peripheral part of the diaphragm via a first edge. An inner peripheral part of a suspension holder is linked with the voice coil member at a linked position which is closer to the magnetic circuit than a linked position of the diaphragm and the voice coil member. An outer peripheral part of the suspension holder is linked with a frame via a second edge. The first edge and the second edge are substantially symmetrical with each other about a median of a first edge and a second edge.

  • Patent number: 7359668
    Abstract: There is described a fixing device equipped in an image forming apparatus, which employs an electro-photographic method for forming an image on a transfer material, and having a lifetime longer than conventional one. The fixing device includes a first roller having a first elastic layer formed in a cylindrical shape on an outer surface of the first roller; and a second roller having a second elastic layer formed in a cylindrical shape on an outer surface of the second roller. A hardness of the second elastic layer is higher than that of the first elastic layer, and a nip section is formed between the first elastic layer and the second elastic layer. A longitudinal length of the first elastic layer in an axial direction of the first roller is greater than that of the second elastic layer in an axial direction of the second roller.

  • Patent number: 7324659
    Abstract: A frame is provided with an opening allowing insertion of a jig for setting an inner rim of a suspension holder to a proper position. The jig ensures positive alignment of the suspension holder when making connection to the frame. The jig also ensures reliable bonding of a diaphragm to the suspension holder with a bonding agent, since it steadily supports the suspension holder in position during the bonding process. The positioning of the bobbin and a voice coil is thus reliable when being assembled, thereby improving acoustic performance of a speaker.
