Title: Wire seam welding method for steel sheet can barrel
Inventor: BAN KUNIKATSU
IPC: B23K101/12
Filed: 1992-09-24
Abstract: PURPOSE:To always maintain welding conditions constant by supplying a wire electrode between a lower roller electrode and an overlap joint so that the flat straightened surface comes into contact with the lower roller electrode. CONSTITUTION:An overlap part 41 of the can barrel 4 is energized and pressurized between upper and lower roller electrodes 1 and 2 and wire-seamed. At that time, one common wire electrode 3 is supplied and passed between the upper and lower roller electrodes 1 and 2 and the overlap part 41. After the wire electrode 3 passes the upper roller electrode 1, the contact surface with the overlap part 41 of the wire electrode 3 is pressurized and the wire electrode 3 is supplied between the lower roller electrode 2 and the overlap joint 41 so that the flat or the substantially flat straightened surface comes into contact with the lower roller electrode 2. The pressurizing force between the upper and lower roller electrodes is increased to 60-90kg/cm<2>. Consequently, even either chemical conversion-treated steel sheet can be subjected to wire seam welding.

IPC: G11B19/20
Filed: 1987-11-05
Abstract: PURPOSE:To prevent the breakdown of a disk by driving the disk a little by rotational driving when the non-rotating state of the disk continues for a prescribed period by providing a timer which drives rotationally the disk at every fixed time in case of the non-rotational time of a magnetic disk. CONSTITUTION:At the non-rotational time of the magnetic disk 14 of an electronic still camera, a timer means 20 counts prescribed time and a system controller 16 drives a disk motor M for a short time through a motor driving circuit. Besides, it transfers a head not shown in a figure successively until the head meets an unrecorded track, and it envelope-detects a reproduced output from the head, and transfers the head until the detected output disappears. After the unrecorded track is detected, the system controller 16 stops power supply to circuits except the means 20, and resets the means 20. When this means 20 begins counting, and it counts the prescribed number, it outputs a count finishing signal, and begins the counting again. The operation of the system controller 16 is stopped until this signal is outputted.

Title: Flip chip mounting method of semiconductor device
Inventor: HARADA YUTAKA
IPC: H01L21/56
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of connection failure in connections and realize high yield after sealing and high reliability in a long term, by applying a pressurizing force on the backside of a semiconductor device at the injection of sealing resin, and excluding the pushing-up of the semiconductor device which is caused by the sealing resin. SOLUTION: A wiring board 1 is put on a stage tilted at 0-20 deg., and sealing resin 7 is spread in the vicinity of a semiconductor device 6 with a dispenser 14. When an extremely narrow gap between the semiconductor device 6 and the wiring board 1 which is 40-60 μm is filled with the sealing resin 7 by using capillary phenomenon, a force pushing the semiconductor device 6 upward works. As a result, a slight gap is generated on the interface of conductive resin 3 of weak adhesive strength and a wiring electrode 2, the sealing resin 7 enters, and open defect is caused. In this case, a weight 9 is so put on the back-side of the semiconductor device 6 that the center of gravity is applied to the spread edge side of the semiconductor device 6, or air blow is performed on the backside.  Thus sealing is performed while the pressurizing force is held on the semiconductor device 6 and the wiring board 1.
