Title: Operation mode setting circuit apparatus for semiconductor DRAM
Inventor: SAWADA SEIJI
IPC: G11C7/22
Filed: 1996-12-10
Abstract: The apparatus includes a correspondence setting circuit (10) and a mode-determining-signal generator circuit (20). Provided with the holding circuit is a locking circuit (12), e.g. an inverter, and a non-locking circuit (14), e.g. a buffer, both connected to a selection circuit (16), e.g. a CMOS transfer gate. Both the inverter and the transfer gate are in receipt of one mode change signal (MCHG) and the buffer is in receipt of a second mode change signal (ZMCHG). The setting circuit changes the correspondence between the state of externally supplied signals (EXT) and the state of internal signals (INT) according to an operation mode change signal (MCHG). These internal signals are then supplied to the mode determination circuit from the setting circuit. The mode determination circuit then supplies a mode signal (MODE) to an internal circuit according to the state of the signal (INT) from the setting circuit.

Patent DE-19818098-A1 (DE)
Title: Implant with improved tissue integration
Inventor: KESSLER HORST
IPC: C12N5/00
Filed: 1998-04-23
Abstract: An implant, for use in various human or animal organs, comprises a carrier matrix enveloped by a peptide coating. The coating contains peptides (I) useful for targetted stimulation of adhesion of body cells. (I) include sequences which recognise binding sites on integrin receptors responsible for adhesion.  The carrier matrix has reactive surface groups capable of forming stable covalent bonds with corresponding functional reactive groups on the peptide layer. (I) are positioned on the surface of the implant such that, due to their structure-related, cell adhesion stimulatory activity, they specifically correspond to the natural complementary integrin pattern in the particular region of the tissue cells neighbouring the area where the implant is to be introduced. Thus a locally differentiated, selective, bioactive coating pattern of the implant surface is provided.
