There is provided a polygermane compound forming a film having a high refractive index and thermal stability, and containing a sulfur atom-containing organic group as a group bonded to a germanium atom. A polygermane compound comprising a sulfur atom-containing organic group as a group bonded to a germanium atom, in which the sulfur atom-containing organic group is a group of Formula [1]:-L-Z&#x2003;&#x2003;[1]where L is a single bond, a Calkylene group, or a Carylene group optionally substituted with a Calkyl group; and Z is a Csulfide group, a Ccyclic sulfide group optionally substituted with a Calkyl group, a Calkyl group containing a sulfide bond, or a Caralkyl group containing a sulfide bond, with a proviso that when L is a single bond, Z is not a Csulfide group.

High heat-resistant polygermane compound with sulfur-containing organic group

Fluorine-containing silicon network polymer, insulating coating thereof,

A bridge apparatus for interconnecting networks in which at least two networks including a plurality of stations are connected, and which, when a transmission frame including an identifier of one station and an identifier of another station of a destination is received from the one station, forwards the transmission frame to a network to which the another station belongs based on the identifier of another station. A processor of the bridge apparatus for interconnecting networks performs delivery control of the transmission frame using an information which has been read out of an address check circuit for identifying the network to which the another station belongs with the identifier of the another station which is included in the transmission frame. The address check circuit comprises at least one hash memory in which hash computation results of respective addresses have been stored at respective address positions, and an address memory for storing a plurality of address informations showing a corresponding relationship between identifiers of respective stations and identifiers of respective networks at respective address positions.

A microstrip line having a shortened line length, includes at least one conductive wire connected between two desired points of a strip conductor through a medium having a second dielectric constant which is smaller than a first dielectric constant. The strip conductor is formed on a substrate which has the first dielectric constant. The effective length of the microstrip line is therefore shorter than the physical length of the microstrip line.
