Title: Substituted phenyl esters of alpha-fluoroacrylic acid
Inventor: HEUMULLER RUDOLF
IPC: C07C51/367
Filed: 1987-06-12
Granted: 1995-07-25
Abstract: Certain esters of  alpha -fluoroacrylic acid are available via hydrolysis of  alpha -hydroxymethyl- alpha -fluoromalonic esters, followed by decarboxylation of the hydrolysis product. Phenyl  alpha -fluoroacrylates which are substituted on the phenyl radical can be prepared by hydroxymethylation of dimethyl  alpha -fluoromalonates, decarboxylation and dehydration of the resultant dimethyl  alpha -hydroxymethyl- alpha -fluoromalonate and esterification of the resultant  alpha -fluoroacrylic acid with substituted phenols. The substituted phenyl  alpha -fluoroacrylates are colourless liquids or colourless solids which are polymerisable. They are suitable as starting material for the preparation of fluorinated polymers.

Title: Checking machine of leakage of steam
Inventor: YUMOTO HEDEAKI
IPC: G01M3/26
Filed: 1987-08-10
Granted: 1990-08-03
Abstract: The liquid-retaining chamber (12,14,16) with inlet and outlet ports (18,20) is partitioned by a bulkhead (22) which divides the central measuring chamber (14) from the outlet chamber 916), and a shorter inclined partition (24) separating the inlet chamber (12) from the measuring chamber (14). The bulkhead incorporates an opening (26) below port level. The water level is measured by a set of electrodes (36a-36n) of different lengths which protrude from an insulating insert (28) in the top of the measuring chamber. Steam leakage is computed from the relationship between the water level and the volumn of gas passing through the opening in the bulkhead. A steam passage (37) is provided through the partition.

Title: Method for reinforcing the steelplate to constructional things
Inventor: LEE SONG-WOO
IPC: E01D19/00
Filed: 1987-10-14
Granted: 1991-03-30
Abstract: This method is to attach the  steel  plate  to  the  existing concrete structure for reinforcement.

Title: Display apparatus and method for contents of self testing in vcr
Inventor: BAEK BOK-HYUN
IPC: G11B27/36
Filed: 1991-12-30
Granted: 1997-05-22
Abstract: The apparatus and method is for displaying self-diagnosis content of VCR. The display apparatus includes: a dew detecting part(2) for detecting whether or not dew is generated on a drum of VCR to input the detected result into a micom(1) which controls display operation of self-diagnosis content; a servo part for generating a hardware signal of 30Hz or 25Hz according to NTSC or PAL mode; a mode switch part(5B) for detecting a converted operation mode according to the operation of a mode converting motor(5A) to input the converted operation mode into the micom(1); a reel pulse signal detecting part(7) for detecting a reel pulse signal generated by the operation of a video tape; and an OSD part(8) for generating a character signal representing abnormality, mixing the character signal with the video signal of the VCR, and outputting the mixed signal according to the control of the micom(1).

Title: Manufacturing method for polor separating membrane
Inventor: KIM JONG-HAK
IPC: B01D61/20
Filed: 1991-12-30
Granted: 1995-05-16
Abstract: The new structure separation membrane module did not use the adaptor and spacer which were the essential parts for the conventional modules by the heat- deformation of tube container which was the body of the module, and it enabled the improvement of the pressure resisting property and the manufacture workability. The tube container which was used as the housing of the separation membrane module was molded and some bundles of hollow fibers were filled into the tube container and adhesion-fixed and then capped for finishing the membrane module.
