Title: A-d converter
Inventor: NEJIME YOSHITO
IPC: H03M1/00
Filed: 1988-02-12
Granted: 1990-10-31
Abstract: The AD converter includes a group of comparators divided into blocks each including 2(power N) comparators (N= 1,2) each comparing an input signal with one of several reference signal, each having individually different voltage levels. One of the comparators may correspond to a level change point where the voltage level of the input signal is higher than that of the reference signal of that comparator which then generates a specific output different from those of the remaining comparators. The converter generates a binary- coded output on the basis of the specific output generated from the level change point comparator. When any one of the comparators generates the specific output, the specific output is applied as an inhibit signal.

Title: Cyclic process for the preparation of (cyclo) aliphatic diisocyanates
Inventor: BOHMHOLDT GERD
IPC: C07C263/04
Filed: 1989-08-18
Granted: 1997-04-28
Abstract: In the preparation of diisocyanates from diamines, urea and alcohols with thermal cracking of the biscarbamate formed, it has hitherto been impossible to utilise the by-products formed in the cracking stage, and thus to arrive at a technically practicable and economical process. It was therefore the object of the invention to search for an appropriate way which avoids the said disadvantages. 
<??>The object was achieved when a cyclic process for the preparation of (cyclo)aliphatic diisocyanates was found wherein, starting from diamines, by-products from the thermal cracking, urea and alcohol, the biscarbamate is produced in the presence of N-unsubstituted carbamates and dialkyl carbonates and with removal of NH3, the subsequent cracking of the biscarbamate is carried out in the liquid phase without solvent, the diisocyanate and alcohol are condensed, the diisocyanate is subjected to a final distillation and a part of the reaction mixture from the cracking with the by-products formed is purged and, after first being reacted with raw alcohol arising, is recycled to the biscarbamate preparation stage.

Title: Polyamide resin composition for manufacturing film
Inventor: YUN KYUNG-KEUN
IPC: C08J5/18
Filed: 1992-06-30
Granted: 1995-12-22
Abstract: Novel polyamide resin compsn. contains 0.01-1.0 wt.% aluminosilicate having 0.1-5 micrometer of ave. particle size and 1.44-1.54 of refraction ratio. The aluminosilicate comprises more than 40 wt.% SiO2 and more than 30 wt.% Al2O3. The film, which is manufactured from the obtd. polyamide resin composition, has excellent friction property, surface glossy property and transparency, then is useful for wrapping food products.

Title: Photomask for control the near pattern effect
Inventor: BAE SANG-MAN
IPC: G03F1/36
Filed: 1992-12-31
Granted: 1996-12-09
Abstract: The photomask increases the process margin by controlling the near pattern effect. The photomask(1) comprises: a chrome substrate(1) transmitting a light; a number of main patterns(2) which copy the image onto a wafer(9), being formed on the chrome substrate(1); and a number of subsidiary patterns(3) which are formed on the chrome substrate(1) where the density of the main pattern(2) is relatively lower than the other regions, and diffract the light transmitted into the region, and are so small that the images are not copied onto the wafer(9).
