Title: Address filter correction system
Inventor: HIRANO TSUGIKAZU
IPC: H04L12/28
Filed: 1987-12-25
Abstract: PURPOSE:To relieve the software load for timer management by eliminating a coincident address when there is any address coincident with a sender address of a packet generated in other local area network. CONSTITUTION:When an address (a) of a terminal equipment of a LAN 1 is moved to a LAN 2, a terminal equipment of the moved address (a) sends a packet to a terminal equipment of an address (d). Since a sender address memory M12 has no address (d), a bridge device 81 transfers the packet to the LAN 1 to store the address (a) to the memory M12. Simultaneously, the bridge device B1 checks whether or not the address (a) is stored in the M11, and since the address is stored, the address (a) is deleted from the sender address memory M11. Thus, the sender address memory M11 of the bridge B1 is corrected. Thus, the address filter is corrected correctly automatically.

Abstract: PURPOSE:To realize an extra-fine and highly integrated circuit by a method wherein high impurity concentration regions of which an NMOS element and/or source and drain regions of the NMOS are composed in a high breakdown strength are formed by utilizing source and drain electrode lead apertures. CONSTITUTION:N-type impurity is implanted by using a gate electrode 13 as a mask to form n<->-type impurity regions 11a and n-type impurity is implanted again through contact holes 14a drilled in a silicon oxide film 14 to form n<+>-type impurity regions 11b. Then a source lead electrode and a drain lead electrode 15 and 15 are formed. Therefore, the source and drain lead electrodes 15 are brought into contact with the n<+>-type impurity regions 11b in a self-alignment manner. Moreover, the source and drain lead electrodes 15 and the high impurity concentration regions 11b can be formed in one photolithography process, so that a margin for the discrepancy of mask alignment can be reduced. With this constitution, an extra-fine and highly integrated circuit can be realized.

Title: Sliding resin composition
Inventor: KANAZAWA SHUJI
IPC: C08L67/00
Filed: 1991-10-17
Abstract: PURPOSE:To obtain a sliding resin composition excellent in slidability and suitable for use especially at high temperature by mixing a thermotropic liquid crystal polymer comprising 4-hydroxybenzoic acid units with a specified fluororesin in a specified mixing ratio. CONSTITUTION:100 pts.wt. thermotropic liquid crystal polymer which is a (co)polymer essentially consisting of monomer units of formula I (e.g. aromatic polyester of formula II) is mixed with 3-50 pts.wt. fluororesin (e.g. polytetrafluoroethylene) having a weight loss of 0.8wt.% or below when kept at 410 deg.C for 30min in air to produce a sliding resin composition. Because the obtained resin composition contains the high-melting polymer, a sliding material made thereof rarely undergoes fusion, seizure, etc., due to frictional heat. Because it contains the fluororesin, it rarely damages a metallic material as a mating member for slide.

Abstract: PURPOSE:To reduce power consumption without decreasing number of stages by providing a coefficient replacement means replacing a coefficient into zero and a coefficient updating means storing plural coefficients after the replacement as required by the coefficient replacement means to plural coefficient storage means to the system. CONSTITUTION:A selection register is provided to each stage comprising a data register, a coefficient register and a multiplier or the like, and a logic 0 is written to a selection register corresponding to a coefficient register in which a coefficient whose absolute value is smaller than a prescribed value is stored, and a logic 1 is written to a selection register corresponding to a coefficient register in which a coefficient whose absolute value is larger than a prescribed value is stored. Thus, no multiplier clock is inputted to a multiplier corresponding to the selection register in which logic 0 is written and then no multiplication is implemented by the multiplier. An output of the multiplier in which no multiplication is executed is replaced to 0 by an AND gate and the result is inputted to an adder. Thus, the power consumption as the entire FIR filter is reduced.
