Title: Discriminating method of quantity of solder by image processing
Inventor: YAMAMOTO TAKAHIRO
IPC: G06T7/00
Filed: 1989-06-28
Abstract: PURPOSE:To detect the quantity of solder of an IC lead by a method wherein irradia tion lights from ordinary light sources are applied at different angles to a solder part at the fore end of the IC lead on a land of a reflow base and the amount of discrepancy between positions of luminance peaks of the solder part and the direction of the discrepancy are identified by an image processing. CONSTITUTION:Irradiation lights from ordinary light sources 15a and 15b are applied at different angles to a solder part 3 at the fore end of an IC lead 2 on a land 1 of a reflow base, the amount of discrepancy between positions of luminance peaks of the solder part 3 and the direction of the discrepancy are identified by an image processing and the quantity of solder is determined in the process of this image processing. When the quantity of the solder in the solder part 3 is adequate, the irradia tion lights 12a and 12b turn to be reflected lights 13a and 13b while forming points of reflection or the luminance peaks 14a and 14b, and enter a camera 16. On the occasion, the point 14b of reflection of the irradiation light 12b at a low position is formed at a position nearer to the fore end of the lead 2 than the point 14a of reflection of the irradiation light 12a at a high position. In this way, the quantity of the solder of the lead 2 can be detected.

Title: Semiconductor circuit
Inventor: BABA TATSUO
IPC: H03K19/096
Filed: 1979-12-24
Abstract: PURPOSE:To obtain an output at a high speed by detecting input signals with high sensitivity, by automatically driving a control circuit according to the potential difference between input signals. CONSTITUTION:Nodes N4 and N5 are previously charged to high potentials and at a proper stage, clock phi2 is held at a high potential. In this state, FETs Q1, Q2 and Q3 are all on and the potential of node N2 is determined by the beta ratio among FETs Q1, Q2 and Q3. Next, when nodes N4 and N5 have a potential difference by the 1st and 2nd input signals S1 and S2, FETQ3 decreases in conductivity and the potentials of nodes N2 and N1 rise. When the potential difference between nodes N4 and N5 exceeds the sensitivity of a control circuit, the voltage of node N1 turns on FETQ8 to drive the control circuit, increasing the potential difference between nodes N4 and N5. Consequently, the conductivity of FETQ3 further decreases and through regenerative feedback, node N4 is held at a low potential to the end to turn off FETQ3, thereby holding node N2 (output terminal) at a high potential.
