Title: Perfluoro polyether composition and its manufacturing method
Inventor: BURKUETE MARIO D
IPC: G11B5/72
Filed: 1984-09-19
Granted: 1992-02-18
Abstract: Polymeric compositions are provided in which perfluoropolyethers have been solubilized in non-fluorinated solvents by combining them with a solubilizing agent such as azotic conjugated compounds, and phosphorylated compounds. Typical of the perfluoropolyethers isTypical of the solubilizing agents is phosphorylated methacryloyloxyhydroxypropylisophthalate. The perfluoropolyether and the solubilizing agent are mixed to form a paste which is soluble in organic solvents such as methylethylketone. These compositions find utility as protective lubricant coatings for thin film magnetic recording media. They have the advantage that only one coating step is required in order to apply both the phosphorylated compound and the lubricating polyether. Recording media lubricated with these compositions have demonstrated excellent wear characteristics.

Abstract: 아치형 부재에 의해 지지되는 구조하에서 토양을 굴착한 후 그 결과로서 발생하는 터널위의 토양의 무게로 인한 아치형 부재의 하강을 막기 위하여, 아치형 부재의 다리부 아래에 배치되는 아치형 부재 지지장치 및 그를 이용한 지지방법을 제공한다. 상기 다리부에는 체임버의 양 측면을 형성하는 두 표면으로 구성되는 베이스가 제공되는 바, 다리부에 연결된 표면은 단단한 반면 지면에 놓인 표면은 유연하며 완충적이다. 상기 두 표면 사이에는 체임버가 배치되며, 상기 체임버는 아치형 부재의 하강을 막기 위해 완충지면상에 변형을 일으키는 유체로 가압된다.

Title: Method for stabilizing image screen of tv system
Inventor: KIM CHOL-MIN
IPC: H04N5/44
Filed: 1991-07-08
Granted: 1993-07-22
Abstract: The image system provided with a picture stabilizing  circuit includes a receiving demodulator (30) for  receiving  an  external image signal to tune and demodulate the signal of a  corresponding channel, an automatic gain control  unit  (40)  for  automatically controlling the output signal gain from the demodulator (30),  and a sync. detector (60) for sensing a sync. signal with  respect  to the image signal of the received channel from the  demodulator.  A microcomputer (20) outputs  two  state  signals  according  to  an external channel altering signal input from a  keyboard  (10)  and the sync. signal, and a switch (50) selects any  one  output  from the unit (40) and a memory (80). When the channel altering  signal is received, the microcomputer outputs the first state  signal  to both the switch and memory.

Title: Spindle motor control circuit of optical recording system
Inventor: HWANG YONG-HA
IPC: G11B7/085
Filed: 1991-07-23
Granted: 1993-08-25
Abstract: In the spindle motor control  circuit,  data  signal  can  be picked up from disk (1) and then  the  signal  transformed  by  RF amplifier is converted to the EMF  rectified  signal  on  the  DSP (30). Next, the switching control signal is produced by the  Micom which receives the input signal from DSP. The  sled  servo  signal from the sled servo (50)  drives  the  sled  motor  (M1)  and  the spindle motor (M2) is  driven  by  the  gain-modulated  rotational servo signal from the gain modulator  (80)  which  receives  input signal from rotational servo (70).
