  • Publication number: 20110042591
    Abstract: A first bar code that is reproduced by linearly polarized red light (first read light) parallel to a short-side direction and a second bar code that is reproduced by linearly polarized green light (second read light) parallel to a long-side direction are recorded on a birefringence label. A probe is a reading device that reads the first and second bar codes from the birefringence label and includes first and second light sources and an imaging unit. The first light source emits the first read light to the birefringence label. The second light source emits the second read light to the birefringence label at a time different from that of the first read light. The imaging unit captures the birefringence label through a polarizing plate having a transmission axis aligned with the short-side direction of the birefringence label, and acquires reproduced images of the first and second bar codes.

  • Patent number: 7838791
    Abstract: A metal coating removing apparatus (1) includes a first electrode (13) arranged so as to be opposed to a metal coating (101) as an object to be removed, a second electrode 14 arranged so as to be opposed to the metal coating (101) at a predetermined distance from the first electrode (13), and a pulse power generator (11), for example, that functions as a discharge energy supply portion. The pulse power generator (11) supplies discharge energy between the first electrode (13) and the second electrode (14) so as to allow discharging to occur between the first electrode (13) and the second electrode (14). By allowing discharging to occur between the first electrode (13) and the second electrode (14), the metal coating (101) can be removed.

  • Patent number: 7282174
    Abstract: The present invention provides a Sn—Zn based lead-free solder which can prevent peeling of solder from soldered portions even after the passage of long periods after soldering of portions to be soldered made of Cu. A Sn—Zn based lead-free solder according to the present invention comprises 5-10 mass percent of Zn, a total of 0.005-1.0 mass percent of at least one substance selected from the group consisting of Au, Pt, Pd, Fe, and Sb, optionally a total of at most 15 mass percent of at least one substance selected from the group consisting of Bi and In, and a remainder of Sn. This Sn—Zn based lead-free solder can be made into a solder paste using a rosin flux containing a halide such as an amine hydrochloride as an activator.
