摘要:
In the rolling process, a rolling amount at each time of rolling by a rolling machine is set to 1 μm to 20 μm, and a magnesium substrate is heated by a constant temperature oven and rolled by rollers. Thus, a magnesium sheet of 30 μm to 100 μm is produced. This magnesium sheet is used to form a bobbin and a diaphragm integrally molded with each other, and the diaphragm is molded into a semi-dome shape or a dome shape. Thus, a bobbin integrated type magnesium diaphragm having the semi-dome shaped diaphragm or the dome shaped diagram is manufactured. The bobbin integrated type magnesium diaphragm is applied to a dynamic speaker device. As a result, the high-quality dynamic speaker device, which realizes high rigidity, high sensibility, high internal loss, less distortion and the like, is obtained.

There is provided an electrically conductive damper device for a speaker in which local bending is reduced and break-downs of material of the damper and metallic wires incorporated in the damper are prevented, by additionally providing one or more sheets of damper fabric as a reinforcing damper 142 and by bonding it to a main damper 141 by way of various kinds of resin, in order to reinforce a neck portion of the electrically conductive damper. Further, properties of the damper can be adjusted by varying an outer diameter of the reinforcing damper 142, or by selecting the resin to be employed as an adhesive.

An example of an optical disc apparatus includes a top case and a bottom case. The top case includes a tab extending downward from one end of the top case. The tab includes a protrusion protruding inward. The bottom case includes a lower-side folded portion formed by folding inward an upper end of one side surface of the bottom case. The lower-side folded portion includes a cantilever spring. The cantilever spring includes a spring portion extending in a vertical direction and a curved portion formed by folding inward an upper part of the spring portion. The protrusion comes into contact with the curved portion when the top case is being affixed to the bottom case and is in contact with the spring portion under a state where the top case is affixed to the bottom case.

A server (3) includes a server communication unit (302) for communicating with a portable terminal (1) and a home appliance (2), a position-determining unit (304) for acquiring information on a position of the terminal (1) during communication, an initial screen storage (305) for storing different position conditions and a collection of screen information defining respective content of initial screens corresponding to the conditions, and an activation unit (306). If position information obtained based on the information on the position acquired through the position-determining unit (304) corresponds to any position condition of the different position conditions, the unit (306) retrieves screen information defining content of an initial screen corresponding to the position condition from the storage (305) to provide the terminal (1) with the information.

A magnetic recording medium includes a recording layer having a granular structure in which magnetic particles are dispersed within a non-magnetic base, and a non-magnetic material embedded in grooves of patterns formed on the recording layer. The magnetic particles have an inverted truncated cone shape with a diameter larger in an upper region of the recording layer than in a lower region of the recording layer.

Provided is a wavelength selective switch which includes: at least one input port; a dispersive portion for dispersing wavelength-multiplexed light input from the input port into wavelength-demultiplexed lights; a condenser element for condensing the wavelength-demultiplexed lights dispersed by the dispersive portion; a deflection portion having deflection elements for deflecting, for each wavelength-demultiplexed light condensed by the condenser element; at least one output port for outputting the wavelength-demultiplexed lights deflected by the deflection portion. A light-condensing position shift compensating element is disposed in an optical path between the input port and the dispersive portion or in the dispersive portion, for compensating light-condensing position shift of the wavelength-demultiplexed lights relative to the deflection element, light-condensing position shift being generated based on the arrangement of the input ports.

摘要:
In an optical disc apparatus, convex portions are provided on the inner surface of a top cover that covers the top surface side of the apparatus such that the convex portions are directly opposite or directly above a flexible printed circuit board during the slide-in/slide-out movements of a tray. The convex portions are positioned further outwardly from the outer circumference of an optical disc with respect to the rotation center of the optical disc upon completion of the slide-in movement of the tray. The convex portions guide or slide part of the flexible printed circuit board along the tip end surfaces of the convex portions in the direction of the slide-in movement of the tray when the part of the flexible printed circuit board comes into contact with the inner surface of the top cover during the slide-in movement of the tray.
