20090028373 | PLANT FOR PRODUCTION OF PAPER-MADE PART FOR SPEAKER, PAPER-MADE PART FOR SPEAKER PRODUCED THEREBY, AND SPEAKER UTILIZING THE SAME - The production equipment of paper-made components for loudspeakers includes a mixing device, a fining device, a paper-making device, and a shape processing device. The mixing device mixes material of a paper-made component for a loudspeaker into liquid to generate mixed liquid. The fining device includes a pressure unit, an orifice, and an inner wall. The pressure unit applies pressure on the mixed liquid to cause the mixed liquid to pass through the orifice, and the mixed liquid collides against the inner wall to cause the fining device to generate fined material. The paper-making device paper-makes the fined material to generate a paper-made component. The shape processing device processes the shape of the paper-made component. This structure provides production equipment of the paper-made components for loudspeakers, which prepares material for paper-making in a short time and reduces producing time. | 01-29-2009 |
20090080687 | SPEAKER DIAPHRAGM, SPEAKER DUST CAP, SPEAKER SUB-CONE, SPEAKER USING THESE COMPONENTS, AND ELECTRONIC APPARATUS USING THE SAME - A loudspeaker of high sound quality is achieved by improving rigidity of a material used for a diaphragm, a dust cap and a sub-cone. The diaphragm, the dust cap and the sub-cone of the loudspeaker are made of a paper beaten with the material containing bamboo fibers obtained from a bamboo tree aged one year or older, of which the fibers are finely beaten to an extent of micro-fibrillated form. The diaphragm and the dust cap are also made with a beaten paper containing at least 2 wt % of “A fibers” having stems of no greater than 30 μm in diameter, and surfaces of the stems are fibrillated into shaggy branches having diameters of 1 μm or less. | 03-26-2009 |
20100027826 | MANUFACTURING METHOD OF PAPER MAKING PART FOR LOUDSPEAKER, PAPER MAKING PART FOR LOUDSPEAKER, DIAPHRAGM FOR LOUDSPEAKER, SUB CONE FOR LOUDSPEAKER, DUST CAP FOR LOUDSPEAKER AND LOUDSPEAKER - A manufacturing method of a paper making part for a loudspeaker has freedom of adjusting a characteristic and a sound quality, and has a higher productivity. Accordingly, a fibrillating step of a paper making material is achieved by an explosive crushing step. Alternatively, the step is achieved by a mixing step of a paper making material and a liquid, a material micro-fabricating step of applying a pressure to a mixed solution obtained by the mixing step so as to pass through an orifice and thereafter run into a device wall, and a paper making step including the micro-fabricated material. | 02-04-2010 |
20120145345 | MANUFACTURING METHOD OF PAPER MAKING PART FOR LOUDSPEAKER, PAPER MAKING PART FOR LOUDSPEAKER, DIAPHRAGM FOR LOUDSPEAKER, SUB CONE FOR LOUDSPEAKER, DUST CAP FOR LOUDSPEAKER AND LOUDSPEAKER - A manufacturing method of a paper making part for a loudspeaker has freedom of adjusting a characteristic and a sound quality, and has a higher productivity. Accordingly, a fibrillating step of a paper making material is achieved by an explosive crushing step. Alternatively, the step is achieved by a mixing step of a paper making material and a liquid, a material micro-fabricating step of applying a pressure to a mixed solution obtained by the mixing step so as to pass through an orifice and thereafter run into a device wall, and a paper making step including the micro-fabricated material. | 06-14-2012 |
20120250930 | SPEAKER DIAPHRAGM AND SPEAKER USING SAME, AND ELECTRONIC EQUIPMENT AND DEVICE USING SAID SPEAKER, AND SPEAKER DIAPHRAGM MANUFACTURING METHOD - A diaphragm is formed of paper manufactured from a first fiber material and a second fiber material. The first fiber material is beaten to have a given freeness, and the second fiber material is made by carbonizing bamboo fiber that has been fibrillated into a microfibril state. This structure allows the second fiber material to increase a rigidity of the diaphragm and also increase an internal loss, so that sound quality of the speaker that employs this diaphragm can be improved. | 10-04-2012 |
20120257781 | SPEAKER DIAPHRAGM, SPEAKER DUST CAP, SPEAKER FRAME, SPEAKER USING SAID PARTS, AND ELECTRONIC EQUIPMENT AND DEVICE USING SAID SPEAKER - Each of a speaker diaphragm, a dust cap, and a frame includes a resin and a plant opal that is extracted from a bamboo leaf, and is formed by injection molding or sheet molding. The configuration can enhance stiffness of each of the diaphragm, the dust cap, and the frame and implement high performance. | 10-11-2012 |
20130301867 | LOUDSPEAKER RESIN MOLDING COMPONENT AND LOUDSPEAKER USING THE SAME AND ELECTRONIC DEVICE AND MOBILE APPARATUS USING THE LOUDSPEAKER - A loudspeaker resin molding component includes resin and bamboo fibers refined to have a microfibril status and carbonized. By this configuration, such a loudspeaker resin molding component can achieve both of a high elastic modulus and a large internal loss. | 11-14-2013 |

20150013907 | MICROWAVE PLASMA PROCESSING APPARATUS, SLOT ANTENNA, AND SEMICONDUCTOR DEVICE - Disclosed is a microwave plasma processing apparatus. The microwave plasma processing apparatus includes a cooling plate. In addition, the microwave plasma processing apparatus includes an intermediate metal body installed on a processing container side of the cooling plate to be spaced apart from the cooling plate so that a spacing between the intermediate metal body and the cooling plate forms a waveguide of microwaves. The intermediate metal body is in contact with the cooling plate at one or plural convex portions arranged to block a portion of the waveguide. Further, the microwave plasma processing apparatus includes a coaxial waveguide configured to supply microwaves to the waveguide, a slot antenna plate configured to radiate microwaves via the waveguide, a dielectric window installed on the processing container side of the slot antenna plate, and a processing container installed to be sealed by the dielectric window. | 01-15-2015 |
