Title: Needle pole's trim finishing method
Inventor: KIM SONG-SHIK
IPC: D04B3/00
Filed: 1985-07-25
Granted: 1987-03-12
Abstract: The bamboo needle, which rotates and is fed by the transfer roller, is ground by a high rotator with th e surface of cotton fabrics. The rotator grinds first the side of a needle at the inclined angle of the rotator side and secondly at an angle of 80-90degrees toward the rotator and by the generated friction heat of 300-330≰C at this time a resin component of the bamboo needle is smelted. Then the mixtures of the resin and dust proceeding from the grinding are coated on a side and an apex part of the needle.

Granted: 1990-05-26
Abstract: An optical disc (D) for audio and video signal recordings is located on a drive unit which has a pair of motors that are selected for the specific use. The output of the head (101) is received by a demodulator (102) with a circuit (103) to separate out the synchronising signal that is compared (105) with a reference signal (107) to close the loop around the motor. Information is demodulated (108) and is entered into a RAM memory (111). Playback is controlled by a signal generator (102) that provides one input to a phase detector (117), with a second input provided by VCO (119). A control signal is provided for read out of the RAM contents that is of a stable time base.

Title: Write clock generator for time base corrector including frequency fluctuation and write clock difference signal reduction
Inventor: TAKAMORI TSUTOMU
IPC: H04N9/89
Filed: 1986-03-20
Granted: 1994-08-31
Abstract: A write clock generator (2, 10) for a time base corrector incorporated in a video tape recorder can generate a write clock signal (WCK) including accurate phase and frequency fluctuation information on a reproduced video signal (VDIN) in spite of a simple circuit configuration. A write clock signal (WCK) is generated from a VCO (12) which oscillats in response to a reproduced burst signal (BURST). Further the VCO (12) is so controlled on the basis of frequency difference (S21) between said generated write clock signal (WCK) and a frequency fluctuation signal (S19) that the frequency difference (S21) may be eliminated. The frequency fluctuation signal (S19) is generated in response to a horizontal synchronizing signal H (SYNC) so as to include time base fluctuations in a reproduced video signal (VDIN).

Abstract: A breakstem blind rivet comprises a deformable tubular shell (11) of aluminium alloy having a bore (12) inside it. A stem (13) of low-carbon steel is a close fit within the bore, extending along the bore and having a head (14) adjacent the tail end (15) of the shell. The outside of the shell is formed with at least three zones (27, 28, 29) of modified strength spaced apart along its length, these zones being in the form of shallow grooves rolled into the surface. The spacing between each zone (27, 28, 29) and the next progressively decreases as the distance along the shell from the tail end (15) increases. Alternatively the grooves may be formed by a turning process.

Title: Active spall suppression armor
Inventor: MUSANTE RONALD E
IPC: F41H5/04
Filed: 1989-09-16
Granted: 1995-03-08
Abstract: A spall backing material (40) contiguously attached to an armor plate (20) at least suppresses the formation of lethal armor spall (24) from being propelled from the inner surface of the armor plate when the outer surface of the armor is impacted by a weapon with sufficient impact to release high velocity spall from unprotected armor. When the impedance of the spall suppression armor is equal to or greater than the impedance of the armor plate, the formation of lethal spall in the armor will be prevented. When the spall backing material is reduced in thickness to minimize weight and has an impedance lower than that of the armor plate, or a more powerful weapon is used, armor spallation will occur but will be suppressed by the spall backing material to minimize lethality.

Title: Method of preparaing expansion carbon
Inventor: KIM JE-YONG
IPC: C01B31/02
Filed: 1991-12-30
Granted: 1994-12-27
Abstract: The pitch that softening point is over 250 deg.C and has optically a potential anisotropy is crushed to below 250 μm of particle size and is dipped in a mixed acid that a volume ratio of nitric acid to sulphuric acid is 1:1 - 1:3 and is agitated at room temperature and filterated. After enough washing filterated residue by water and drying, the expansive carbon is made by heating at over 600 deg.C under inert gas. This can expand to several hundred times.
