    摘要： A delay measuring device according to the present invention comprises a memory cell, a delay element and a selector. The memory cell is provided with a non-inversion output terminal and an inversion output terminal, and the memory cell fetches a data value inputted from outside in synchronization with a clock, retains the fetched data value and outputs the retained data value from the non-inversion output terminal and the inversion output terminal. The delay element is connected to the inversion output terminal. The selector selects one of the data value and a delayed data value outputted from the delay element and supplies the selected data value to the memory cell. In the present invention, a comparison result of making a comparison between a delay amount generated in the delayed data value and a time length defined based on the clock is outputted from the non-inversion output terminal.

    摘要： With use of separated alloy powder (10) as a sintering material, it is possible to utilize characteristics of metals of different types (SUS steel and Cu, for example). Further, a boundary surface between regions constituted by different metals is at least partially alloyed. Thus, it is possible to enhance bonding strength between the regions, and possible to enhance strength of a sintered bearing.
