Patent DE-4221251-A1 (DE)
Title: Laser welding composite sheet - without encountering problems resulting from vaporised plastic gases
Inventor: KINZEL ANDREAS
IPC: B23K26/242
Filed: 1992-06-26
Abstract: Method of welding together plate which consist of two steel layers sandwiching a plastic central layer consists of using the laser-thermal conduction welding process in which the cover layers are bonded together without touching the central plastic layer. The two outer layers can be simultaneously welded using two lasers or one layer with a divide beam. Alternatively the weld can be a deep weld forming across the whole thickness of joint. In this case the plastic layer in the area of the weld is removed prior to welding by mechanical, or thermal means, esp. by laser beam. USE/ADVANTAGE - In metal sheet working, esp. body work. Provides the problems of vaporised plastic gases which lead to deteriorationin the weld quality.

Title: Semiconductor memory device circuit and semiconductor memory device structure realising the latter
Inventor: CHOI JUNG-DAL
IPC: G11C17/12
Filed: 1994-03-04
Abstract: To increase the integration density, it is known to combine a plurality of memory elements into chains and to connect one or more chains to a single bit line. The accompanying increase in stray capacitance of the bit line and in the capacitance of the transition of bit line and memory element chain leads to higher delay times on the bit line and consequently to a lower operating speed. In the case of the novel semiconductor memory device circuits, a bipolar current-driver transistor (Q4, Q5, Q6) is respectively provided between one end of a memory element chain and a bit line (BL-1, BL-2, BL-3), so that the current flow through the bit lines is increased and consequently so too is the operating speed. A layered structure for realising such a circuit is also specified. In addition, a SRAM device with current-driver transistors is proposed. <IMAGE>
