Title: Method for production of heat-resistant structured layers
Inventor: HELLMUT ANNE
IPC: C08G18/48
Filed: 1986-06-24
Granted: 1994-09-29
Abstract: A cost-efficient method for producing dimensionally precise and high-grade heat-resistent structured layers by applying a single coating of a radiation-sensitive soluble polyether-based photopolymer in the form of a layer or foil on a substrate; irradiating the layer or foil through a negative with actinic light or by guiding a light, electron, laser, or ion beam; removing the nonirradiated layer or foil portions; and subsequent optional annealing, wherein the photopolymer comprises an addition product of an olefin-unsaturated monoisocyanate and a polether having at least one hydroxyl group. The layers provided according to the invention can withstand the thermal and mechanical stresses of dip soldering process, and protect circuit surfaces effectively and durably against moisture and corrosion; they are therefore suitable in particular as solder resist and insulating layers in microconductor technology.

Title: Tdm communication system with synchronizing circuit in receiver responding the coding of words inserted in the transmitted information
Inventor: WEIS BERND X
IPC: H04J3/06
Filed: 1990-07-07
Granted: 1998-12-01
Abstract: There are time division multiplex information transmission systems in which synchronisation takes place by means of code words transmitted at regular time intervals and coded in a particular code. In systems in which the signals to be transmitted are transmitted in packets of uniform length, the code words in each case contain the information of the so-called header of a packet. The test device according to the invention tests all n-bit bit groups (Xj to Xj+n-1) beginning with an (Xj) of the successive bits of the bit sequence received successively for whether they are coded in the particular code. This is done by calculating the syndrome (S1 to Sn-k) in several parallel networks (N1 to Nn-k), each of which calculates one syndrome component. The bit sequence received is delayed until the networks have calculated the syndrome for a particular n-bit bit group and a syndrome evaluating circuit (LS) indicates, by means of the calculated syndrome, whether the bit group is a code word. <IMAGE>

Title: Method of fabricating a nand type mask rom
Inventor: JO HUNG-SHIK
IPC: H01L27/112
Filed: 1991-07-11
Granted: 1993-12-24
Abstract: The mfg. method of a NAND type mask ROM is  characterized  by (a) forming a source/drain junction region (12), a gate  electrode (13) and an aluminium wiring layer (15) on the  P  type  substrate (11), (b)  covering  an  insulating  film  (16)  of  500-2000 ∦ thickness, (c)  patterning  a  photoresist   and   implanting   a phosphorus, and (d) removing the photoresist and heat treating the metal wiring at 450-550 deg.C to activate the implanted phosphorus ion. The method can be applied  for  an  after  metal  programming (AMP) and an after passivation programming (APP).

Title: Extended memory access method
Inventor: JONG JAE-HAK
IPC: G06F12/06
Filed: 1991-12-05
Granted: 1994-06-23
Abstract: The method for accessing an extended memory includes the steps of writing data contents of a file and generating a higher address corresponding thereto; checking whether a memory position to be written is an end of a block; if not, writing data to an extended memory, increasing a lower address by 1, and requesting data processing; if the memory position is the end of the block, displaying the use of the block and checking whether the next block is overflow; if so, terminating the whole series of steps; if not, returning to the step of writing data, thereby reducing the processing time of a central processing unit.
