Abstract: The new organic electroluminescent display device has a carrier-transporting layer and/or an organic luminous layer composed of a nematic liquid crystal or a liquid crystal dispersing a carrier-transporting low-molecule therein. When the organic luminous layer is to be bestowed with faculty as a liquid crystal, it is made of a nematic liquid crystal. Both the carrier-transporting layer and the organic luminous layer may be bestowed with faculty as a liquid crystal. Since the liquid crystal is incorporated in the carrier-transporting layer and/or the organic luminous layer, the display device can be driven as a liquid crystal display device in a dark place by charging with a voltage lower than a light emission initiating potential. Of course, it is driven as an electroluminescent display device when it is charged with a voltage higher than the light emission initiating potential. Use of an electroluminescent liquid crystal as a organic luminous layer enables omission of a carrier-transporting layer.

Abstract: A Vibration system part for a speaker device includes a woven fabric or a non-woven fabric made of basalt fiber produced by twist yarn or roving yarn being a continuous long-fiber. The vibration system part for the speaker device may be a diaphragm, a center cap, an edge or a damper, for example. In a preferred example, the woven fabric or the non-woven fabric is impregnated with thermosetting resin or thermoplastic resin. Additionally, a lamination member, such as paper, foam material, resin or a film, is preferably laminated (coated) on the woven fabric or the non-woven fabric. Thus, the vibration system parts for the speaker device, having excellent acoustic property and reliability, can be obtained at a low price.

Abstract: A speaker device where the dip in the middle sound range is reduced, which provides reproduced sound of comparatively high quality, and provides reproduced sound of comparatively high sound pressure. In the speaker device, a support member for a speaker vibrator is adopted for an edge. The speaker device has a movable part (85) having bent parts, or more specifically, having a top bent part, an inner bent part, and an outer bent part. Because the movable part (85) is formed such that the top bent part is positioned closer to the radial center of the speaker device than the radial center between the inner bent part and the outer bent part, the edge (8) has comparatively high rigidity. Consequently, the dip in the middle sound range can be reduced by a simple structure without forming, for example, a damping agent layer and a resin layer on the support member for a speaker vibrator.

Abstract: A thread winding part or a reinforcing wire winding part is formed by winding a heat resistant fiber thread or a reinforcing wire around the voice coil bobbin in contact with both coil ends of the wire winding part or a coil end of the same on a magnetic-circuit side. A bent part bent outward is formed on the lower end of the voice coil bobbin on the magnetic circuit side. This prevents the wire winding part from shifting from its mounting position and from coming off to the lower side. In the resulting voice coil, the wire winding part hardly comes off the voice coil bobbin even if the wire binding of the wire winding part is loosened by Joule heat, speaker vibrations, etc.

Abstract: A voice coil bobbin is formed by skinpass rolling of pure titanium. A manufacturing method of a voice coil bobbin includes a process which manufactures a rolled pure titanium material, a process which executes skinpass rolling of the rolled material, and a process which forms the rolled material after the skinpass rolling to manufacture the voice coil bobbin.

The peak brightness control means 29 is controlled using this APL value so that PLE operation of controlling a peak brightness of the picture signal is realized.
