Inventor: TAKENAKA SHINYA
IPC: G06K7/10
Filed: 1990-01-09
Abstract: A mark reading device that reads marks such as a bar code, or the like on a remote surface.  A laser beam is outputted, deflected through a scan angle and the reflected energy is read at a detector. This energy is processed and converted to a usable format for input into a computer, cash register, or any type of data collection device. The present invention improves depth of field and readability by varying the output energy of the laser after each successive scan, thus providing a range of energy levels at the detector.

Abstract: The invention relates to a blind riveting member of the type comprising a tubular sleeve (1) and a mandrel (2) passing through said sleeve. The stem portion (5) of the tubular sleeve (1) comprises successively along its length, a first articulation zone (5a), an inclined portion (5b), a second articulation zone (5c) and an end portion (5d). These zones or portions are arranged in such a manner that the sleeve is subjected to a double folding during setting of the rivet which causes the inclined portion to expand and fold back upon itself toward the materials being assembled, forming a continuous rest surface at the periphery of the hole which contains the riveting member. The invention is applied in particular for assembling fragile materials such as composite materials. It permits providing a good vibration resistant holding for these materials without risk of damaging the same.

Abstract: A  multitool punch holder (12) having a head  member  (26) coupled  to  a punch press ram (16) as the press  upper  turret plate  (22)  rotates  to  bring  the  punch  holder  (12)  into alignment with the ram (16).   The punch holder (12) includes a rotary  tool  carrier (56) carrying a series of  punches  (80), each  able  to be selectively rotated into alignment beneath  a striker  rod  (100)  slidably mounted in a  non  rotating  body member  (30).   Stroking of the ram (16) causes  an  engagement feature  (108)  to engage the striker rod (100) when  the  head member  (26)  telescopes into the body member (30) after  axial movement  of  the holder (12) is arrested by contact  with  the workpiece (120).  The striker rod (100) is then driven to force the  coupled  individual punch (80) into the  workpiece  (120). The  striker  rod  (100) is urged to a raised  position  by  an encircling  stripper spring (110).   A separation  spring  (42) urges  the ram (16) and body member (30) to retracted  position with  the  striker  rod (100) out of engagement  with  the  ram engagement  feature (108).   A detachable striker plate (88) of urethane provides non-marring contact with the workpiece (120).
