Title: Copper alloy for terminal and connector having superior migration resistance
Inventor: MIYATO MOTOHISA
IPC: H01B1/02
Filed: 1986-04-21
Abstract: PURPOSE:To improve the migration resistance of a Cu alloy by specifying the amounts of Ti, Fe and Zn in the alloy so as to increase the electric conductivity. CONSTITUTION:The composition of an alloy is composed of 0.1-1.0wt% Ti, 0.2-2.5wt% Fe, 1.5-4.0wt% Zn and the balance essentially Cu. In the composition, Zn is an essential element required to inhibit the migration of Cu and the generation of a leakage current in case where water infiltrates between electrodes under applied voltage. By the composition, 50% IACS electric conductivity can be satisfied. The Cu alloy is usable as a material for household and industrial machine parts and automotive parts requiring a large current capacity, e.g., a terminal and a connector.

IPC: H04N5/335
Filed: 1985-05-01
Abstract: PURPOSE:To achieve deep isolation characterized by the small amount of etching and the narrow isolating width, by forming a high concentration semiconductor region beneath an insulating region. CONSTITUTION:On an N-type silicon substrate 1, an N<-> type epitaxial layer 4 is formed. A P-type base region 10, an N<+> type emitter region 12, a capacitor electrode 11 and the like are formed in the layer 4. A collector electrode is formed on the back surface of the substrate 1. An element isolating region is formed by an insulating region 8 and an N<+> type region 7 directly beneath the region 8. The insulating region 8 is formed by embedding an oxide in a recess part that is formed by etching. A suitable voltage is applied to the N<+> region 7 with an element isolation controlling electrode 14. Since the high concentration semiconductor region is formed beneath the insulating region, deep isolation characterized by the small amount of etching and the narrow isolating width can be achieved. Since the amount of etching is small, damage on the semiconductor can be alleviated.

Title: Data transfer method
Inventor: NAKAYAMA RYOHEI
IPC: H04L12/46
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To reduce the processing load of an IP router and to cancel the processing neck of the router by establishing the transfer route of an IP packet, omitting the assembling processing of the IP packet after that and executing data relay. SOLUTION: A transmission passage between the IP routers is established during the transfer of the IP packet. In the transmission passage, a virtual channel(VC) is set between the routers when a wide range network is ATM and a transfer path is set in the routing table of the IP router at the time of private line. After the transmission passage is established, an FC header is removed from an FC frame received from the FC terminal of the IP router, the FC frame is dissolved into cells through applying VC so as to be transferred when the wide range network is the ATM network and a routing header is added so as to execute transfer at the time of the private line. Since transfer frame destinations where connection is set are the same in the IP router after the establishment of the transmission passage, transfer is executed to the transmission passage at every frame without assembling the FC frame in the IP packet.

Title: Manufacture of soi substrate
Inventor: SEGUCHI YOHEI
IPC: H01L21/20
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a silicon-on-insulator(SOI) substrate, which enables efficient restoration of damages due to ion implantation. SOLUTION: A high concentration of oxygen ions is first implanted into a silicon substrate 1 to form a high-concentration oxygen-implanted layer 3. Then, in order to form a buried oxide layer 5, the substrate is subjected to a heat treatment at 1350 deg.C for about 4 hours in an Ar atmosphere containing oxygen having a concentration of 0.5%. Next, for melting and re-crystallization of a surface silicon layer, the substrate is subjected to a pulse laser annealing process. A pulse laser emits a beam having an energy density of 1200 mJ/cm<2> or more. Since the power density of the beam at the time of the emission is as very great as 10<7> W/cm<2> , the semiconductor surface can be melted in several tens of nsec.  When the pulse laser annealing is repeated, the melting and re- crystallization are repeated, whereby the movement of crystal defects can be activated and crystal damage restoration based on crystal seeds can be realized.
