Title: Electronic time piece with at least two motors
Inventor: TRIPONEZ ANDRE
IPC: H02K16/00
Filed: 1990-04-20
Granted: 1999-06-15
Abstract: The timepiece comprises an electromagnetic motor (100) whose stator (2) is flat and covered at least partially by a strengthening plate (68) made of non-magnetic material or, if need be, material with very low magnetic permeability which has been fixed thereto, preferably by soldering, before it was subjected, in bulk, together with others, to an annealing in order to protect it at the time of this operation against the risks of deformations and of fractures which would have rendered it subsequently unusable. According to the invention and in order to prevent this plate becoming a useless supplementary piece which takes up space in the timepiece, it comprises means which enable it to constitute, at the same time, another element of this timepiece. This element may be, for example, a spring/setting-lever jumper (72) which interacts with a setting lever (212) in order to define stable positions of a manual control rod (184) which may be displaced axially. <IMAGE>

Abstract: 본 발명은 피복된 디이프 드로잉 가공 캔의 제조 방법에 관한 것이다. 특히, 본 발명은 피막의 접착성, 내부식성, 내열성 및 내덴팅성이 우수한 피복된 디이프 드로잉 가공 캔의 제조 방법에 관한 것으로서, 본 발명의 주목적은 열가소성 수지로 피복된 금속판을 드로잉 또는 디이프 드로잉 가공하여, 수지 피막이 접착성이 향상되고, 내부식성, 내열성 및 캔의 덴팅 저항성이 향상된 피복된 디이프 드로잉 가공 캔을 제조하는 방법을 제공하기 위한 것이며, 또 다른  목적은 수지 피막이 원래 갖고 있는 필름 특성을 손상시키는 일이 없이 금속판에 대한 수지 피막의 접착성이 향상되고, 그 수지 피막의 내열성이 향상된 피복된 디이프드로잉 가공 캔의 제조방법을 제공하기 위한 것이다. 
     본 발명에 따르면, 금속판을 열가소성 수지로 피복하고, 이 피복된 금속판을 드로잉 및 디이프 드로잉 가공하여, 피복된 디이프 드로잉 가공 캔을 형성한 다음 성형시킨 피복된 디이프 드로잉 가공 컵을 열가소성 수지 피막의 유리 전이점보다 높은 온도에서, 그러나 열가소성 수지 피막의 융점 이하의 온도에서 열처리하는 것을 현저한 특징으로 한다. 
     또한, 상기 온도에서 수행되는 열처리에 의해, 드로잉 및 재드로잉에 의해 연신되고 분자 배향되는 수지층은 금속 컵에 고정되고, 변형이 억제된 상태에서 열경화된다. 즉, 이러한 열처리에 의해, 내부 응력이 제거되고, 결정화도가 증가되며, 수지층의 분자 배향을 완화시키는 일이 없이 접착 부위의 활성화가 일어남으로써 피복된 디이프 드로잉 가공 캔에 대한 덴팅시험을 수행한다 하더라도, 수지 피막에 균열이 발생하지 않는다. 더욱이, 피복된 디이프 드로잉 가공캔은 표면 광택, 즉 광택이 우수하다는 이점이 있다.

Title: Powder coating method for metallic surfaces
Inventor: PROBST THOMAS
IPC: B05D1/14
Filed: 1991-09-20
Granted: 1999-09-15
Abstract: In electrostatic powder coating, the starting materials used are metal surfaces which are furnished with an oil film for protection against corrosion during storage and transport. The polymer powder is applied to the surface without removing the oil film. The powder layer is then melted in an oven and is finally cured by cooling. The heat applied by the oven should be sufficient to volatilise the oil. An oil is preferably used which remains stable or resistant during the heating process as long as it remains on the workpiece surface. This includes the possibility that individual components or the entire oil diffuse through the powder layer and evaporate during the heating-up process, or alternatively that part or all of the oil quantity remains on the workpiece during the heating process and mixes with the powder layer. In both cases, the quality of the plastic coating is not adversely affected by the oil film.

Abstract: 본 발명은 광디스크 시스템에 있어서 디스크면의 불량을 검출하여 디스크면의 불량을 보상하기 위한 것이다.  이를 위하여 디스크면의 불량상태를 검출하기 위한 디스크면 불량검출부와, 포커싱 제어신호를 증폭시키기 위한 포커싱 제어신호 증폭부와, 주변환경변화에 대하여 안정되고 동일한 레이저 파워를 출력하도록 제어하기 위한 레이저 파워 제어부와, 레이저 다이오드를 구동하기 위한 레이저 다이오드 구동부를 구비한 광디스크 시스템의 광디스크면 불량보상장치에 있어서, 디스크면 불량검출부에서 출력되는 신호를 소정의 증폭값을 갖도록 증폭하기 위한 증폭수단과, 증폭수단에서 출력되는 신호와 포커싱 제어신호 증폭부에서 증폭되는 신호를 선택적으로 스위칭하기 위한 스위칭수단과,  수위칭수단으로 선택적으로 출력되는 신호를 레이저 파워 제어부에서 출력되는 신호에 가산하여 레이저 다이오드 구동부로 인가하기 위한 가산부를 포함하도록 구성된다. 
     따라서 디스크면의 불량정도에 따라서 레이저 파워를 증감시켜 출력함으로써 디스크면의 불량을 보상할 수 있다.

Title: Image encoding apparatus
Inventor: LIM JONG-TAE
IPC: H04N19/625
Filed: 1992-12-11
Granted: 1997-11-26
Abstract: the first means compressing sequential pixel data presented as data format using 2-dimensional relation of digital image signals to present the first compression encoded signal in case that intra mode is selected; the second means compressing sequential pixel data presented as data format using 1-dimensional relation of digital image signals to present the second compression encoded signal in case that inter mode is selected; and a switching means(112) receiving control signals from the means determining said inter or intra modes to connect the digital image signals inputted as prescribed image processing unit to said first or second means; is disclosed.
