Title: Device for transferring single sheets to the offset cylinder of a rotary sheet-feed printing press
Inventor: GERMANN ALBRECHT JOSEF
IPC: B41F21/00
Filed: 1991-07-20
Granted: 1999-03-30
Abstract: The device has a transfer cylinder (2) with a drum (4) which is adjustable in the circumferential direction relative to its shaft (3) and which carries sheet grippers (8) with a front stop (8a) for the sheets (B). The diameter of the transfer drum (2) is equal to 1/N of the diameter of the plate cylinder which carries N printing plates. The shaft (3) of the transfer cylinder (2) rotates at a constant speed and executes N revolutions when the plate cylinder is executing one revolution. By means of a controllable setting device, the drum (4) is so displaced relative to the shaft (3) during each revolution that the front stop (8a), when its transfer position in which a sheet is transferred to the impression cylinder (D) is passed, assumes a position by which the exact register of this sheet in relation to the position of the printing plate printing it on the plate cylinder is set. This guarantees that the width of the front margin between the sheet front edge and print start is of the same size on all the printed sheets, without the need to adjust the printing plates exactly on the plate cylinder in a time-consuming way.

Abstract: An automatic opener of a pack(P) having an inlet conveyer(20) mounted in one side of a frame(10) to moving a sack filled with contents; a disk shape fixed cutter(30) mounted in central upper part of the inlet  conveyer(20) to cut the partial front part and one side of the pack(P); a moving cutter(40) mounted in central upper part of the inlet conveyer(20) to cut the other front part and the other side of the pack(P); a pair of pinch rollers(50) pulling one end of the opened pack(P); a discharging  conveyer(70) feeding the opened pack(P); a discharging hoper(80) guiding contents dropper from the pack(P) and mounted in lower part of the discharging  conveyer(70); and a shaking  shaft(90) shaking out the remnant contents of the pack(70) is disclosed. Thereby, a number of packs can be quickly and simply opened without many labor, thus it is possible to greatly reduce working time and costs.

Abstract: Method of forming a solder bump using lapping technique defines a photoresist of a solder bump deposition thickness, uses a lapping process, thereby solving a problem of a thick film photoresist pattern process of a prior lift-off method. Also, the method obtains a desired solder volume by adjusting a height after depositing a solder, thereby increasing an accuracy of a solder bump forming process. The method includes the steps of: sputtering a predetermined UBM(under-bumped metal) layer on a semiconductor bonding pad, and forming a damping oxide film(3) on a part excepting the bonding pad(1) area; forming a thick film photoresist(4); light-exposing and developing the thick film photoresist(4) by a predetermined light-exposer having a hydrogen or cadmium ultraviolet rays source; depositing a solder(5) on the thick film photoresist(4) and on the bonding pad(1); performing a lapping until the solder bump deposited on the bonding pad(1) is exposed in order to remove the solder(5); removing a remaining thick film photoresist(4); reflowing the solder bump(6) on the bonding pad(1) defined as the damping oxide film(3) in 5 minutes of 350deg.C and N2 atmosphere, and making a solder ball format.
