Title: Wire dividing and controlling device
Inventor: SAITOU YOSHIYUKI
IPC: B21C47/00
Filed: 1980-06-17
Abstract: PURPOSE:To cut the prescribed position although the rolling conditions vary, by detecting the two division points of a rolled member from the rolling length and then tracking these division points until they reach a coil converging device. CONSTITUTION:When the tip of a rolled member 1 is detected by a material detector 16, a counter CTR1 counts the pulses sent from a pulse transmitter 18. Then a coincidence signal 21 is transmitted to a counter CTR2 when a coincidence is obtained between the count value of the pulse and the value set to a setter DSW1, and thus the counter CTR2 counts the pulses sent from a pulse generator 20. When a coincidence is obtained between the value of the counter CTR2 and the set value of a setter DSW2, a detection signal S2 is delivered to drive an iris driving device and a cutter driving device 13. In this case, the value from a detection of the tip to an arrival of the two division points to a conveyer 5 is set to the setter DSW1; while the value with which the two division points reach a cutter 11 is set to the setter DSW2 respectively.

Title: Thin film wiring structure
Inventor: DOI HIROAKI
IPC: H01L23/538
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent exfoliation which is the bottleneck of multilayered wiring, by forming a plurality of protrusions on the bonding surface to insulator. SOLUTION: Cu wiring 12 is formed in polyimide 1 on an Si substrate 2, and connects LSI chips 4. Many cylindrical protrusions 13 are formed on the Si substrate 2. The manufacturing method is as follows; photosensitive resist is spread on the Si substrate 2 and baked, a circular pattern resist is developed by photolithography, and a lot of the protrusions are formed by etching the Si substrate 2. Thereby, spin-coated polyimide 1 is sufficiently stuck around the protrusions 13 of the Si substrate 2, and the bonding area is increased, so that the bonding strength is increased.  Since the coefficient of linear expansion of the polyimide 1 is large as compared with that of the Si substrate 2, the protrusions 13 are fastened by the polyimide 1 as the result of thermal contraction of the polyimide 1 caused by cooling, and compressive force is generated on the surfaces of the protrusions 13, so that the bonding strength of the polyimide 1 and the protrusions 13 is further increased.
