Title: The method of herical type magnetic recording
Inventor: UCHIUMI SATOSHI
IPC: G11B15/087
Filed: 1985-07-30
Granted: 1990-05-14
Abstract: The method uses a system storing in the tape an identification signal when only sound or data is being recorded. The ident. signal is put down at a given place in each scan and when detected during subsequent scanning is taken to indicate the presence of sound and causes the rotary head to act in its audio mode during that scan. The information is recorded across the tape at several places. The ident. signal is placed at least at one blank part amongst the places. The blank part lies immediately after one edge of a switching pulse.

Abstract: The actual engine speed of an engine in an idling state and a difference between the actual engine speed and a targeted idling engine speed preset in accordance with the operating state of the engine are detected.  The detected difference and a reference difference are compared with each other to determine whether the power steering system is operated to a point close to an operatable limit when the automobile is at a standstill.  The engine speed is rapidly returned to the targeted idling engine speed by increasing a proportional term of a gain in proportional-integral type feed-back control.

The detector comprises a voltage controlled oscillator (15)  providing the reference frequency signal, a N  divider  (17)  providing  two clock signals in oposite phases, a phase detector  (10)  detecting the  phase  and  frequency  deviation,  and  a  loop  filter  (15) providing the control voltage for varying  the  frequency  of  the oscillaotr.

Title: Position control method of robot
Inventor: SONG JIN-IL

Abstract: The  method  controls  position  of  a  robot  arm  based  on differential  state  equation   and   S-shape   acceleration   and deceleration profile so that chattering of a robot arm is  reduced and high speed and  precise  position  control  is  obtained.  The method includes the steps of: (A) calculating the  maximum  number of position deviation of each axis; (B) calculating  the  distance of each axis  to  be  moved  during  sampling  intervals  when  no accerleration and deceleration motion occurs; (C) calculating  the moved distance of each axis; (D) calculating position deviation of each axis; and (E) calculating control input of  each  axis  using proportional integral and differential control scheme (PID).

Title: Assemblies of ptc circuit protection device
Inventor: HORSMA DAVID A
IPC: H01C7/02
Filed: 1989-07-14
Granted: 1999-05-15
Abstract: A device assembly in which a plurality of PTC circuit protection devices are connected in series. Assemblies of this type are useful in providing protection under voltage conditions which would be unsafe for an individual protection device. In a preferred system the device assembly is connected in series with a circuit breaker.

Abstract: 패드형 완충깔개 제조용 스티칭 장치 및 콘버터기 
     완충 깔재 제조용 콘버터기에 사용하는 기어형 스티칭 장치에 관한 것임. 시이트상 원자재는 공급 로울로부터 공급되고 양측 연부가 내측으로 말려 패드상으로 형성됨. 스티칭 장치는 서로 치합되는 한쌍의 기어형 회전부재로 구성되고 두 부재사이를 통과하는 시이트상 원자재의 중앙부를 압착함. 기어형 부재중의 최소한 한 부재의 기어치에 돌조가 형성되어 있어서 패드상 제품의 중앙 연결부를 압착할 때 구멍 또는 함입부를 형성하므로서 연결부에서 양측에서 말린 연부가 서로 합체되어 완제품이 패드상을 유지하게 된 것임.
