What is claimed is:
1. A process for producing a conductive damper for use in a speaker, in the process a workpiece of the conductive damper, in which knitted tinsel wires are integrated with a sheet-shaped workpiece, is set between top and bottom molds, on the surface of each of which a plurality of corrugations are formed concentrically, then the workpiece of the conductive damper is pressed by the top and bottom molds so as to be molded in a damper-shape, the process comprising:
a first step, in which the workpiece of the conductive damper is set on the bottom mold;
a second step, in which the top mold is moved in the direction nearer to the bottom mold so as to mold one corrugation or a plurality of corrugations for the inner part of the workpiece of the conductive damper; and
a third step, in which the top mold is further moved in the direction nearer to the bottom mold so as to mold one corrugation or a plurality of corrugations for the outer part of the workpiece of the conductive damper, wherein the third step is repeatedly performed so that the workpiece of the conductive damper is molded in a damper-shape.
2. The process for producing a conductive damper for use in a speaker according to claim 1, wherein the third step is performed once and the second step is performed twice.
3. An apparatus for producing a conductive damper for use in a speaker, including top and bottom molds, on the surface of each of which a plurality of corrugations are formed concentrically, by using the apparatus a workpiece of the conductive damper, in which knitted tinsel wires are integrated with a sheet-shaped workpiece, is set on the bottom mold, then the workpiece of the conductive damper is pressed by moving the top mold so as to be molded in a damper-shape, the apparatus comprising:
a bottom mold, on the surface of which a plurality of corrugations are formed concentrically;
at least two divided top molds including a first top mold and a second top mold, which are formed by concentrically dividing the top mold into the inner part and the outer part and provided with a plurality of corrugations at positions corresponding to the corrugations of the bottom mold; and
a moving mechanism moving up and down independent of the first and second top molds, including:
a base, to which the second top mold is mounted;
guiding means provided to the base for controlling a movement of the first top mold in the up-and-down direction; and
energizing means provided to the base for energizing the first top mold to press the second top mold, wherein by moving the base downward, the inner part of the workpiece of the conductive damper is press-molded between the first top mold and the bottom mold, then the outer part of the workpiece of the conductive damper is press-molded between the second top mold and the bottom mold.
4. The apparatus for producing a conductive damper for use in a speaker according to claim 3, wherein the first top mold is divided concentrically into a plurality of divided molds, each of which has the guiding means and the energizing means.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A device for facilitating conveyance of a substance out of a receptacle, comprising a connector and a container which form an integrated unit, wherein said connector comprises a first connector element for connection to said receptacle, said container is designed to have a flexible portion, said container or said flexible portion comprises a displaceable spring-loaded element that is arranged to allow fluid to flow into said container or said flexible portion wherein said container is pre-filled with a cleaned fluid to be transferred from said container to said receptacle, wherein said receptacle is connectable to said connector element of said connector, during conveyance of a substance out of said receptacle, wherein said cleaned fluid is gas, liquid, or a combination of gas and liquid, and wherein conveyance of said substance out of said receptacle is capable of occurring as soon as said connector element is arranged on said receptacle since cleaned fluid will be transferred from said container to said receptacle as said substance is conveyed out of said receptacle, wherein said container and receptacle are positioned orthogonal to each other.
2. A device according to claim 1, wherein said fluid is sterilized.
3. A device according to claim 1 or 2, wherein the volume of the container is variable.
4. A device according to claim 3, wherein said container is made of a compressible material to make the volume of the container variable.
5. A device according to claim 3, wherein the container comprises a locking element configured to prevent fluid from flowing into the container.
6. A device according to claim 3, wherein said connector comprises a second connector element for connection to a transfer member for conveyance of a substance out of a receptacle.
7. A device according to claim 1, wherein said container is pressurized by cleaned or sterilized fluid to cause an overpressure in the container which overpressure is adapted to the size of the receptacle to which the connector is to be connected.
8. A device for facilitating conveyance of a substance out of a receptacle, comprising a connector and a container which form an integrated unit, wherein said connector comprises a first connector element for connection to said receptacle, said container comprises a bellow that is collapsible and extendable by affecting the container manually by a user wherein said container is pre-filled with a cleaned fluid to be transferred from said container to said receptacle, wherein said receptacle is connectable to said connector element of said connector, during conveyance of a substance out of said receptacle, wherein said cleaned fluid is gas, liquid, or a combination of gas and liquid, and wherein conveyance of said substance out of said receptacle is capable of occurring as soon as said connector element is arranged on said receptacle since cleaned fluid will be transferred from said container to said receptacle as said substance is conveyed out of said receptacle, wherein said container and receptacle are positioned orthogonal to each other.
9. A device according to claim 8, wherein said fluid is sterilized.
10. A device according to claim 8, wherein the volume of the container is variable.
11. A device according to claim 10, wherein said container is made of a compressible material to make the volume of the container variable.
12. A device according to claim 10, wherein the container comprises a locking element configured to prevent fluid from flowing into the container.
13. A device according to claim 10, wherein said connector comprises a second connector element for connection to a transfer member for conveyance of a substance out of a receptacle.
14. A device according to claim 8, wherein said container is pressurized by cleaned or sterilized fluid to cause an overpressure in the container which overpressure is adapted to the size of the receptacle to which the connector is to be connected.
