Title: Manufacture of stem for semiconductor device
Inventor: YATANI TATSUO
IPC: H01L23/373
Filed: 1984-04-23
Abstract: PURPOSE:To prevent the creep-up of solder by increasing the effective area of the top by a method wherein a heat sink is fitted into the through-hole of a flange so that a surface having a curved part at its shoulder may become the bottom, and the gap is filled by forming an annular groove. CONSTITUTION:The surface having the curved part 5a at the shoulder being made as the bottom, the heat sink 5 is fitted into the through-hole 3 of the flange 1. When the annular groove 10 is formed by caulking the neighborhood of the curved part 5a, the thickness present at the part of the groove 10 is pushed away to the outer periphery, and the gap 9 between the flange 1 and the heat sink 5 becomes then eliminated. Glass bullets 7, 7' are fitted into the through- holes 4, 4 of the flange 1, assembled by inserting leads 8, 8, and heated to 950- 1,050 deg.C, when the leads 8, 8 are sealed, and the heat sink 5 is hermetically brazed to the flange 1 with a solder 6. Such a manner enables the increase of the effective area of the top on account of the absence of a curved part at the shoulder of the heat sink top and prevents the fused solder from creeping up to the heat sink top across the curved part.

The X and Y stages 12, 13 are controlled from a controller 17 so that the fringe section 19a section is projected by a TV camera 15. A picture processor 16 recognizes and processes the picture of the fringe section 18A section while taking in the picture signal of the fringe section 18A section, turns a table 11 and detects a notch section 10A. The X and Y stages 12, 13 are moved, and the picture of the fringe section 18A section is photographed by the TV camera 15. The X and Y stages 12, 12 are moved again, and the leftest position of the tabular article 10 is measured regarding the picture at the fringe 18B section.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To perform accurate position tracking in spite of small scale remodeling by tracking the position of a carried object using only the rotation speed of the carried object carrying rollers on which the carried object is placed in order. SOLUTION: The calculation to detect the position of a steel material 8 is started when it is recognized that the steel material 8 is positioned at a reference position by the head and tail detection signals output from the inlet side hot metal detector of a certain speed control section, and the movement from the place is performed by integrating the pulses sent from the first roller rotation detector PL1, and then multiplying the result by the moving distance per one pulse. In the tracking using this roller rotation detector PL1, it is required for accurate tracking to switch the first roller rotation detector PL1 to a roller rotation detector PL2 when the steel material 9 passes through the first roller rotation detector PL1 and moves to the next roller rotation detector PL2.  This switching operation is performed by detecting that the steel material 8 has moved to the carrying roller R3, on which the roller rotation detector PL2 is provided, from the load torque current of the motor M3 of the carrying roller R3.

Filed: 1989-03-31
Abstract: PURPOSE:To stick a developer on the surface of a supporting body to constant thickness irrelevantly to the thickness of the supporting body even if the thickness of the supporting body varies by adjusting the coating amount of the developer on the supporting body according to information from a measuring means. CONSTITUTION:This developer coating device consists of a means 50 which measures the thickness of the supporting body P and a developer coating amount adjusting means which adjusts the coating amount of the developer S on the supporting body P according to the information from the measuring means 50, and the developer coating amount adjusting means consists of a control means 41 and a rotation control mechanism for a conductive roller 22. Then an electric field matching the polarity of the developer S which is charged electrostatically in a developer transfer area 27 is applied to move the charged developer S from a developer carrier roller 21 to the supporting body P and stick it on the supporting body. At this time, the coating amount of the developer on the roller 21 varies by the variation in the scatter amount of the developer S with the thickness of the supporting body P, so the feed speed of the supporting body P is controlled by the control means 41 to a value matching the thickness of the supporting body P. Consequently, even if the thickness of the supporting body P varies, the developer can be stuck on the surface of the supporting body to the constant thickness irrelevantly to the thickness of the supporting body P.
