Title: Radio channel lan system and its control method
Inventor: SHIGESA HIDEHIKO
IPC: H04W12/08
Filed: 1993-03-05
Abstract: PURPOSE:To attain re-transmission in a MAC layer by a base station equipment by providing a mobile terminal equipment management database and a mobile terminal equipment verification database to the base station equipment and providing a management source recognition database to a mobile terminal equipment respectively. CONSTITUTION:A base station equipment 10 executes re-transmission only to a mobile terminal equipment 20 registered in a mobile terminal equipment management database.

Filed: 1985-03-08
Abstract: PURPOSE:To attain the application of address interleave by providing a means to each main memory to receive access start designations for the data and key memory parts independently of each other and executing the access to one or both of the data and key memory parts. CONSTITUTION:A main memory 1 designates a byte address by an access request address 10 with 32 bits (the 0-th-31st). It is shown that the desired data exists at the data memory parts MSU 0 and 1 when the 25th bit is equal to '0' and '1' respectively. Thus either one of data memory part start latches 11-0 and 11-1 is turned on by the 25th bit. Then it is decided centering on 8 mega-bytes whether a key exists in a main memory 5-0 or 5-1. As a result, the access starts are carried out at a time with the same address to both memories 5-0 and 5-1. However, one of four cases is designated by the combination of latches, and the accesses are carried out in parallel to both data and key memory parts by both main memories.

Abstract: PURPOSE:To improve the dimensional accuracy of a resin section in a coaxial type resin molding semiconductor device, and to enhance printing and the positional accuracy of taping by inserting the semiconductor device between an elastic roller and a pedestal and giving revolution and downward pressure by pressure. CONSTITUTION:Lead wires at both ends of a coaxial type resin molding semiconductor device 1 to which a projecting burr 2 is formed are placed on conveying chains 6 moved in the direction of the arrow first. The coaxila type resin molding semiconductor device is moved among elastic rollers 7 manufactured by a rubber, etc. and pedestals 5 manufactured by ceramics, etc. by the conveying chains second. The lead wires 3 are inserted gradually among several elastic roller 7 and pedestal 5 by the conveying chains. The moving coaxial type resin molding semiconductor device is not inserted among the pedestals 5 and the pedestals 5 because the projecting burr 2 is formed, and is elevated only by the size of the burr. Downward pressure is applied to the lead wires 3 inserted among the pedestals 5 and the elastic rollers 7 by the elastic rollers because the pedestals 5 and the elastic rollers 7 are brought into contact shortly. Accordingly, the projecting burr 2 can be removed by the hard sharp edge sections of the pedestals 5.

Title: Fabrication method of semiconductor device
Inventor: YONEMURA TOSHIO
IPC: H01L21/52
Filed: 1978-04-18
Abstract: PURPOSE: To prevent migration with the reduction of the material cost by placing noble-metal foil on the surface of a pad and by coating the surface with a high-speed rotating bar pushed.  
     CONSTITUTION: The tip of metal-bar polymer 2 coated with hard-to-migrate copper, Ni, etc., is flattened to make pad 6. Metal bar 8 which is thick enough to be inscribed in pad 6 and has its tip flattened is fitted to rotary shaft 9 rotating at a speed of more than 3000 r.p.m. Then, pushing bar 8 against pad 6 by force of 10 to 20kg via noble-metal foil 7 of 80 to 100μ in thickness cleans the pad surface, so that noble-metal film 12 will be fused by fricton. In the above method, fusion-welding of copper and silver is possible. Further, since the only pad surface is coated with noble metal, the material cost is reduced and coating the metal wire with inexpensive copper prevents migration after resin sealing.
