Abstract: PURPOSE:To prevent a crack from being caused while a thermal stress is absorbed by using a coupling particle and to enhance heat-dissipating performance by forming a gap between substrates by a method wherein, when the semiconductor substrates for lamination use are laminated three-dimensionally, the semiconductor substrates are laminated mutually by using the coupling particle. CONSTITUTION:A conductive coupling particle composed of a metallic substance which has been filled into a hard cylindrical body and a hard cylindrical body, whose inside diameters differ from each other, in such a way that the particle protrudes partly from an end part at the side of a smaller inside diameter is fixed to a pad 3 of a coupling hole 7 in a semiconductor substrate 6 for lamination use. As this fixing method, the semiconductor substrate 6 for lamination use is set on a retention stage 35 in such a way that an opening of the coupling hole 7 faces upward; after that, a gun barrel 32 is aligned with the coupling hole 7 in the semiconductor substrate 6. A temperature of the retention stage 35 is increased to 300 deg.C by using a built-in heater 34; after that, the outside of the gun barrel 32 is maintained at about 350 deg.C by using a heater 31; a conductive coupling particle 19 is inserted into the gun barrel 32 and is discharged with accelerated velocity while the coupling particle 19 is being heated by compressed nitrogen 36. The semiconductor substrate 6 for lamination use where the conductive coupling particle 19 has been fixed to an exposed part of the pad 3 corresponding to the coupling hole 7 via a protruding part 17 is thereby obtained.

Abstract: A device for manufacturing molded articles of plastics material which have an outer skin of a plastics material free of expanding agents and a porous core of a plastics material containing an expanding agent includes an extruder head with a main duct in communication with a discharge opening. Two feed ducts for the two plastics materials lead angularly offset into the main duct at locations axially spaced from the discharge opening and from each other. A closing needle is axially movably placed in the main duct. The two feed ducts can be separated from the main duct by means of the closing needle. The closing needle defines a connecting duct extending essentially in axial direction. The connecting duct ends at the end face of the closing needle and at the circumference of the closing needle radially toward the more remote feed duct. In the closed axial position of the closing needle and in an at least partially open axial position of the closing needle, the radial circumferential opening of the connecting duct is located approximately on the same level as the inner radial outlet opening of the more remote feed duct. The closing needle is rotatable about the longitudinal axis of the extruder head relative to the outlet opening in any axial position of the closing needle.

Abstract: This invention relates to apparatus for offering wireless telecommunication service. Pairs of the transceivers (21,31; 22,41; 23,42) of a wireless cell site (1) are directly interconnected. When a request for service is received, a controller allocates a pair of the transceivers to handle the call. If the call is to the public switched telephone network, an unconnected transceiver (24,32) is connected to a switching system, such as a toll switch (80), and a protocol converter (60) converts between call control messages to and from the cell site and call control messages to and from the toll switch. If the cell site has directional antennas, a pair of transceivers connected to the directional antennas for serving the calling (8) and called stations (35) is selected; transceivers (51,52) connected to an omni-directional antenna can be used for overflow traffic and for traffic between the toll office and the cell site. Advantageously, the need for switching is avoided by selecting appropriate transceiver pairs and tuning the mobile stations to the correct channels. <IMAGE>

Abstract: A portable device is disclosed which can deliver various combinations of scents in rapid succession directly to a user's nose. The device uses a blower fan (2) which forces air through a fragrance chamber (4). The flow into the chamber is regulated by an inlet valve (5) and an outlet valve (6). The valves (5,6) can be manually, electrically or pneumatically actuated. The valves (5,6) can be of an on/off or proportional flow type. The air carries away the scent molecules which have entered the gas phase. This air is then mixed with the air from all other fragrance holders in the packed bed mixer (11). The final mixture is delivered to the user via nasal tubing (20) and is emitted right below the wearer's nose. A mask covering the nose can be used to deliver the scent to the user. The scent is then drawn away from the nose and into a scent scrubber (38).
