Title: Line multiplexing device
Inventor: KAISE HIROSHI
IPC: H04J3/00
Filed: 1990-03-01
Abstract: PURPOSE:To switch data with a small line capacity by providing a line table management mechanism and changing contents of a line management table in accordance with the demand. CONSTITUTION:An exchange 1 assigns input lines of a multiplexer 2 and releases connection to exclusively switch data at each time of a request of a data terminal equipment 7 or a telephone set 8. The exchange 1 is provided with a line management table 6. The multiplexing mechanism 2 allows lines from the telephone set and the data terminal to correspond to plural logical lines, into which a high-speed line is divided with respect to time, in 1:1. A line table managing mechanism 3 registers information of an assignment ratio of audio lines and data lines or the like set in a table data holding mechanism 4 and develops this information on the table 6 by a console 5. In accordance with information in a line management table 6, the number of extensions is limited and a fixed line capacity for response holding is reserved at the time of switching. Since the circuit constitution can be dynamically changed, data is switched with the same line capacity as a conventional system even at the time of peak superposition of audio lines and peak lines.

IPC: G01N3/42
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To perform indentation hardness measurement without receiving any influence even from the noise produced on a screen by a worn indenter. SOLUTION: An indentation hardness measuring instrument can easily specify the shape of an indentation even in such a case that the conventional instrument is not able to specify the shape of the indentation from the inside of the indentation due to noise mixed in the indentation by setting an indentation searching extent 12 on the outside of a photographed indentation 21 and searching the boundary line of the indentation 21 by scanning the extent toward the indentation 21 from the outside of the indentation 21. In addition, since the exchanging cycle of the indenter of the instrument is extended, the burden of the indenter exchanging work and the parts cost of the indenter can be reduced.
