    • A semiconductor integrated circuit device is disclosed which comprises a plurality of cell rows each including a plurality of standard cells, signal connection cells provided one at each of the cell rows and located on one straight line across that cell row array, a line for connection cells which is connected to the signal connection cell and adapted to supply a signal which is propagated via the signal connection cell to the cell in the corresponding cell row, and cell-to-cell connection lines each connecting the signal connection cells together and having a broader connection width than that of an ordinary connection line. In the semiconductor integrated circuit device of the present invention the respective signal connection cells are connected together by the cell-to-cell connection line having a broader connection width than that of the ordinary connection line, so that a signal is propagated to the respective cell row in a low-resistance way. The respective signal connection cells are each arranged at the respective cell row in a manner to be located on a single straight line to achieve the reduction of a distance between the signal connection lines. Since a signal coming from the signal connection cell at each cell row is supplied in a row unit to the associated cell in the respective cell row via the connection line for cell rows, a signal propagation over a minimum connection line length is assured.

    • A mechanical seal comprises, in addition to a rotating seal element, a stationary seal element, and a support ring: means for securing the support ring to a rotating shaft in such a manner that, between a casing and the shaft, the ring remains nonrotatable by the shaft but can travel axially following any axial movement of the shaft. The securing means comprises nonrotational stop means located between the casing and support ring and means located between the ring and shaft to permit the both to rotate relative to each other but keep them from moving axially. The nonrotational stop means is a combination of pins and holes, key ways and keys, or the like, and the means located between the ring and shaft to permit the both to rotate is either a pair of rolling bearings or a plurality of journal bearings plus a thrust sliding bearing.
