Chip orientation sensor

Claim 1

AN APPARATUS FOR SUCCESSIVELY SENSING THE ANGULAR POSITION OF SEMICONDUCTOR CHIPS HAVING THREE BALL CONTACTS ARRANGED IN A TRIANGULAR RELATION COMPRISING, A BASE, A HEAD MOUNTED ON SAID BASE, A BLADE GUIDE MOUNTED ON SAID HEAD AND HAVING A CONCAVE DEPRESSION AND FOUR RELATIVELY THIN RADIALLY ARRANGED SLOTS, FOUR PIVOTED LSHAPED ARMS, MEANS PIVOTALLY SUPPORTING SAID ARM ADJACENT SAID BLADE GUIDE, EACH OF SAID L-SHAPED ARMS ARRANGED WITH A RELATIVELY LONG LEG PORTION EXTENDING DOWNWARDLY AND A RELATIVELY SHORT LEG PORTION DIRECTED INWARDLY GENERALLY IN ALIGNMENT WITH ONE OF SAID SLOTS, A RELATIVELY THIN BLADE MOUNTED ON EACH OF SAID ARMS ON THE SHORT LEG THEREOF WITH A PORTION DISPOSED IN ONE OF SAID SLOTS IN SAID BLADE GUIDE, AN ELECTRICAL SWITCH ASSOCIATED WITH EACH OF SAID BLADES, EACH OF SAID ELECTRICAL SWITCHES HAVING A FIRST FLEXIBLE ELECTRICAL CONTACT ON SAID BASE POSITIONED IN OVERLYING RELATION TO THE END PORTION OF A DOWNWARDLY EXTENDING LONG LEG PORTION OF ONE OF LSHAPED ARMS, AND SECOND ELECTRICAL CONTACT ON SAID BASE POSITIONED IN SPACED RELATION TO SAID FIRST FLEXIBLE ELECTRICAL CONTACT, MEANS FOR ALIGNING A CHIP RELATIVE TO SAID BLADES COMPRISING, A PAIR OF SLIDABLE DIAMETRICALLY POSITIONED GUIDE JAWS ON SAID HEAD, CHIP ENGAGING PORTIONS ON SAID JAWS POSITIONED ABOVE SAID ADJACENT SAID BLADE GUIDE, RESILIENT MEANS BIASING SAID JAWS INWARDLY, MEANS FOR OPENING SAID JAWS, SAID LAST MENTIONED MEANS HAVING LSHAPED LEVERS, EACH LEVER HAVING ONE END IN ABUTTING ENGAGEMENT WITH ONE OF SAID JAWS, A PISTON AND CYLINDER, A PISTON ROD IN OPERATIVE ACTUATING ENGAGEMENT WITH THE OPPOSITE ENDS OF SAID LEVERS, AN AIR PASSAGE COMMUNICATING WITH SAID CYLINDER AND TERMINATING IN SAID BLADE GUIDE, SAID APPARATUS IN USE ADAPTED TO SENSE THE ANGULAR POSITION OF THE CHIP WHEN THE CHIP WITH THE BALL CONTACTS DOWN IS MOVED DOWNWARDLY GUIDED BY SAID JAWS INTO CONTACT WITH SAID BLADES, AND PRODUCE AN ELECTRICAL SIGNAL WITH THE ELECTRICAL SWITCHES IN RESPONSE TO ACTUATION OF SAID BLADES BY THE BALL CONTACTS.

Claim 2

AN APPARATUS FOR SUCCESSIVELY SENSING THE ANGULAR POSITION OF SEMICONDUCTOR CHIPS HAVING THREE BALL CONTACTS ARRANGED IN A TRIANGULAR RELATION COMPRISING, A BASE, A HEAD MOUNTED ON SAID BASE, A BLADE GUIDE MOUNTED ON SAID HEAD AND HAVING A CONCAVE DEPRESSION AND FOUR RELATIVELY THIN RADIALLY ARRANGED SLOTS, FOUR PIVOTED LSHAPED ARMS, MEANS PIVOTALLY SUPPORTING SAID ARM ADJACENT SAID BLADE GUIDE, EACH OF SAID L-SHAPED ARMS ARRANGED WITH A RELATIVELY LONG LEG PORTION EXTENDING DOWNWARDLY AND A RELATIVELY SHORT LEG PORTION DIRECTED INWARDLY GENERALLY IN ALIGNMENT WITH ONE OF SAID SLOTS, A RELATIVELY THIN BLADE MOUNTED ON EACH OF SAID ARMS ON THE SHORT LEG THEREOF WITH A PORTION DISPOSED IN ONE OF SAID SLOTS IN SAID BLADE GUIDE, AN ELECTRICAL SWITCH ASSOCIATED WITH EACH OF SAID BLADES, EACH OF SAID ELECTRICAL SWITCHES HAVING A FIRST FLEXIBLE ELECTRICAL CONTACT ON SAID BASE POSITIONED IN OVERLYING RELATION TO THE END PORTION OF A DOWNWARDLY EXTENDING LONG LEG PORTION OF ONE OF LSHAPED ARMS, AND SECOND ELECTRICAL CONTACT ON SAID BASE POSITIONED IN SPACED RELATION TO SAID FIRST FLEXIBLE ELECTRICAL CONTACT, MEANS FOR ALIGNING A CHIP RELATIVE TO SAID BLADES COMPRISING, A PAIR OF SLIDABLE DIAMETRICALLY POSITIONED GUIDE JAWS ON SAID HEAD, CHIP ENGAGING PORTIONS ON SAID JAWS POSITIONED ABOVE SAID ADJACENT SAID BLADE GUIDE, RESILIENT MEANS BIASING SAID JAWS INWARDLY, MEANS FOR OPENING SAID JAWS, SAID LAST MENTIONED MEANS HAVING LSHAPED LEVERS, EACH LEVER HAVING ONE END IN ABUTTING ENGAGEMENT WITH ONE OF SAID JAWS, A PISTON AND CYLINDER, A PISTON ROD IN OPERATIVE ACTUATING ENGAGEMENT WITH THE OPPOSITE ENDS OF SAID LEVERS, AN AIR PASSAGE COMMUNICATING WITH SAID CYLINDER AND TERMINATING IN SAID BLADE GUIDE, SAID APPARATUS IN USE ADAPTED TO SENSE THE ANGULAR POSITION OF THE CHIP WHEN THE CHIP WITH THE BALL CONTACTS DOWN IS MOVED DOWNWARDLY GUIDED BY SAID JAWS INTO CONTACT WITH SAID BLADES, AND PRODUCE AN ELECTRICAL SIGNAL WITH THE ELECTRICAL SWITCHES IN RESPONSE TO ACTUATION OF SAID BLADES BY THE BALL CONTACTS.
