  • Patent number: 6122257
    Abstract: In a bus type LAN, the data transmitted from a terminal (14) is detected by an adapter (1) connected to one end of a bus (3), and in response thereto the adapter (1) transmits a pulse signal onto the bus (3). An adapter (2) connected to the other end of the bus (3) receives the data transmitted from the terminal (14) and detects its source terminal address. A difference in time between the arrival of the data from the terminal (14) and the arrival of the pulse signal from the adapter (1) is measured by a counter circuit (21), and the count value obtained is stored in a memory (23), forming a pair with the corresponding source terminal address. Thus, the count value can be obtained for each terminal during the normal operation of the LAN. The data of the memory (23) are extracted by a personal computer (5), where the physical position of each terminal is calculated in accordance with the bus propagation velocity, and is displayed or printed out as a physical constitution diagram.

  • Patent number: 5477976
    Abstract: A brightening chemical polishing solution for a hardened steel article (e.g., a carburized and quenched gear) comprises hydrofluoric acid having a molar concentration of from 0.2 to 2 mol/l, hydrogen peroxide having a molar concentration of from 0.4 to 4 mol/l, and water, a molar ratio of the hydrofluoric acid to the hydrogen peroxide being from 1:1.5 to 1:2.8. The steel article is quench hardened and is chemically polished in the solution. A shot-peening is additionally performed, prior to the polishing.

  • Patent number: 5184346
    Abstract: A switching system exchanges communication information as fixed length cells between a plurality of incoming and outgoing highways. The fixed length cells each have a plurality of data portions with one data portion designated as a header portion for containing switching information. An address generating circuit generates read addresses and write addresses in response to the header portion of each cell and a control circuit. The plurality of cells from the incoming highways are simultaneously rotated in a rotation matrix with each of the cell's data portions rotated to a unique internal path. The data portions are then transmitted to identical write addresses in a plurality of memories via delay circuitry. The write addresses are transmitted through shift registers to the plurality of memories to allow the data portions of a single cell to occupy identical addresses within a plurality of memories.

  • Patent number: 4947388
    Abstract: A fixed-length packet switching system, in which fixed-length packets (cells) each composed of a header portion and a data portion are received from a plurality of input lines, and after conversion of the header portions, the received packets are transmitted onto selected ones of output lines designated by their header portions.

  • Patent number: 4821551
    Abstract: There is disclosed a technique characterized by the following steps. An axial load is applied from both ends of a primary tube while locally heating the primary tube by use of a high frequency coil in the peripheral direction, and the heated portion is thereby bulged. The application of load is stopped almost concurrently with termination of the heating process. The heated portion is forcibly cooled with a cooling liquid, thus molding one crest. Then the primary tube and the high frequency coil are relatively moved. The next crest is formed by repeating the foregoing steps. Such operations are consecutively repeated in the axial direction of the primary tube, thereby obtaining a corrugate tube formed with crests having a large amount of bulge and a small pitch.
