Patent JP-H01192237-A (JP)
Title: Digital subscriber line transmission system
Inventor: SUZUKI TOSHIO
IPC: H04L12/28
Filed: 1988-01-27
Abstract: PURPOSE:To recognize the constitution of a subscriber line automatically and to provide each node address automatically by establishing its own address every time address information passes a node and inhibiting the propagation of address information to the outgoing node when the address is not established. CONSTITUTION:A relay circuit 3 converts address information received via an address channel in an outgoing information channel 10 from a station side terminal circuit 1 to a subscriber side terminal circuit 2 based on prescribed conversion and the result of conversion is propagated as address information of the outgoing node. The subscriber side terminal circuit 2 converts the address information from the incoming side based on the same conversion and returns the result as the final address to the station side terminal circuit 1 via the incoming information channel. The station side terminal circuit 1 based on the final address recognizes the node number and constitution up to the subscriber side terminal circuit 2 by the known conversion. Moreover, a provided inhibition address is set and informed during address uncertainty and the provision of erroneous address due to error address information during uncertain address or updated address is prevented without preparing individual display channel.

Title: Core drill and core drill with holder
Inventor: KOIDE AKIMICHI
IPC: B23B51/00
Filed: 1995-02-06
Abstract: PURPOSE: To set each length of diameter of both holding and wire tool parts to the desired size in an easy manner by installing this wire tool whose base end side is fitted in a minimum diameter pipe out of multistage pipeattached tight thereto, and the tip side is projected at the specified length from a tip of the minimum diametral pipe. CONSTITUTION: A maximum diametral pipe 1a of about 0.5mm in diameter, about 20mm in length and 0.11mm in thickness and a minimum diametral pipe 1b of about 0.25mm in diameter, about 20mm in length and about 0.07mm in thickness both are fitted in two stages in a bushing manner forming a multistage pipe. In addition, a wire tool 2 made of a piano wire of about 0.09mm in diameter and about 50mm in length is fitted in this minimum diametral pipe 1b and attached tight. Each gap among those of pipes 1a, 1b and wire tool 2 is secured tight by means of brazing of silver or the like. Thus a core drill D1 is formed up, and thereby a variation ranging from a diameter of the maximum diametral pipe of this multistage pipe to that of the wire tool is reducible stepwise, so such a possibility that a stress might be partially concentrated is preventable, insofar as possible.

Abstract: PURPOSE:To effectively utilize the two-dimensional excitons formed at crystal boundaries by laminating plural layers of org. nonlinear optical materials consisting of condensed polycyclic hydrocarbon respectively via intermediate layers. CONSTITUTION:The nonlinear optical material layers 2 consisting of anthracene and the intermediate layers 3 consisting of, for example, polymethyl methacrylate are laminated successively on a quartz substrate 1. The org. nonlinear materials are laminated in the form of layers in such a manner and since the respective layers are set at thicknesses of one molecular layer to several molecular layers, the bulk excitons do not exist in the org. nonlinear materials of the respective layers and, therefore only the two-dimensional excitons are formed. The two-dimensional excitons formed at the crystal boundaries of the nonlinear optical material consisting of the condensed polycyclic hydrocarbon, such as anthracene, are effectively utilized in this way.
