Provided is a broadcast control apparatus that realizes broadcasting to a predetermined distribution area, as in an existing public mobile communication network in a communication system using a femto cell base station. The broadcast control apparatus includes a database, in which location information of the femto cell base station existing in a predetermined distribution area section is associated with the distribution area section. The broadcast control apparatus also includes update means for updating the association in the database based on the location information of the femto cell base station received by reception means.

The femto cell base station is a femto cell base station that connects a UE (User Equipment) to a core network side and includes storing means and control means. The storing means retains subscriber information of the UE visiting an area under control of the femto cell base station. The control means deletes the subscriber information of the UE, that is removed from the control of the femto cell base station, from the storing means.

A flat speaker comprising a vibrating plate including a spiral voice coil, a lead portion extracted from the vice coil and reinforced by the reinforcing member, and an electric supply line; an edge portion supporting the vibrating plate; and a yoke, supporting the edge portion, on which the permanent magnet arranged to face the voice coil. The flat speakerof the invention includes a vibrating membraneof an insulating base filmwith a spiral or meandering voice coilformed on one or both faces thereof, a permanent magnetarranged on corresponding location facing the voice coil; and a yokeon which the permanent magnetis arranged. The vibrating membraneis avoided from hitting the permanent magnet by providing a perforated sheet on the back face of the yoke to control acoustic resistance.

A zoom lens includes, in order from an object side to an image side, a first lens unit having a negative refractive power and a second lens unit having a positive refractive power. In the zoom lens, an interval between the first and second lens units becomes smaller at a telephoto end than at a wide-angle end during zooming. The first lens unit includes, in order from the object side to the image side, a first lens having a negative refractive power, a second lens having a negative refractive power, which is made of a plastic and has an aspheric lens surface, and a third lens unit having a positive refractive power. In the zoom lens, a refractive index and an Abbe number of the plastic (Nd, &#x3bd;d), a focal length of the second lens (fn), and a focal length of the first lens unit (f) are appropriately set.

Disclosed is a key sheet having a base sheet equipped with a hard resin plate and a key sheet manufacturing method, wherein a reduction is achieved in the thickness of the base sheet and in the effort and cost for the molding. Further, accurate depressing operation is realized without impairing the outward appearance of the key sheet. The key sheet has a hard base plate having a communicating groove connecting through-holes with each other. The communicating groove has a connecting portion formed so as to be continuous and integral with operating portions formed respectively at the through-holes. Thus, there is no need to form inlets for a rubber-like elastic material respectively corresponding to the through-holes in the mold. As a result, the mold structure can be simplified to thereby achieve a reduction in cost. Further, since the entire front or back surface of the hard base plate is not covered with the rubber-like elastic material, it is possible to achieve an overall reduction in the thickness of the base sheet.

A zoom lens includes first to fourth lens units which respectively have negative, positive, negative, and positive refractive powers in order from the object side to the image side. Distances between the first and second lens units, the second and third lens units, and the third and fourth lens units at the telephoto end are respectively smaller, larger, and smaller than those at the wide-angle end. An Abbe number &#x3bd;1n and a partial dispersion ratio &#x3b8;1n of a material of at least one negative lens included in the first lens unit, an Abbe number &#x3bd;1p, a partial dispersion ratio &#x3b8;1p, and a refractive index N1p, respectively, of a material of at least one positive lens included in the first lens unit, a focal length f1 of the first lens unit, and a focal length fw of the entire system at the wide-angle end are adequately set.
