Perhaps you should try some spelling variations:
"raja ravi cmos roy" » "raja ravi cmos from", "raja ravi cmos co", "raja ravi cmos ram"
"raja ram cmos ics" » "raja m cmos ics", "raja r cmos ics", "raja roy cmos ics", "raja from cmos ics", "raja a cmos ics"
"raja nm cmos rf" » "raja m cmos rf", "raja n cmos rf"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("raja ravi cmos roy") OR ("raja ram cmos ics"))) OR ("raja nm cmos rf")).
• Removing quotes may allow a broader search: (((( raja ravi cmos roy ) or ( raja ram cmos ics ))) or ( raja nm cmos rf )).
• Adding a wildcard symbol may retrieve word variants: (((("raja ravi cmos roy") or ("raja ram cmos ics"))) or ("raja nm cmos rf"))*.
