Abstract: A method for controlling a darkness of an image is disclosed. First, a white image is generated to an A/D converter. At this time, an input compensation value is set in order to sense a white image to an white value. And then the output of the ABC circuit is connected to the input of the A/D converter by a switching process. The image data is read based on the compensation value which is obtained by the input compensation value and a limit value. Thereafter, it is determined whether the read image data exists within an image spec range. When the read image data does not exist within an image spec range, the limit value is changed and a previous process is repeated. When the read image data exists within an image spec range, the compensation value is stored as a comparing compensation value.

Abstract: 강재표면에 이온비임을 조사한 후, 표면온도를 100∼400℃로 유지하고, 계속하여 강재를 진공상태 하에서 증착도금한다. 이온비임의 조사는, 0.05쿨롱/㎡ 이상의 조사량으로 실시하는 것이 바람직하다. 증착도금은 종류가 다른 금속재료를 순차적으로 또는 동시에 증착시키면서 실시한다. 
     또, 강재의 현열을 이용할 수도 있다. 이 경우, 이온비임조사 후의 강재가 강온하는 과정에서 표면온도가 100∼400℃의 범위에 있을 때, 진공상태하에서 증착도금한다. 강재표면의 온도를 100∼400℃의 범위로 유지하는 것에 의해서, 피도금재료 표면에 형성된 다수의 활성점을 기점으로 하여 도금금속이 증착되어서, 밀착성, 가공성, 내식성, 도막밀착성이 우수한 도금층이 형성된다.

Abstract: 본 발명은 코어가 있는 회전전기기계의 스테이코어의 돌극에 권선의 단부처리구조의 개량에 관한 것으로서, 단자나 후크등의 돌기부품을 이용하지 않고 돌극으로의 권선의 권회 및 회로기판으로의 결선을 가능하게 하여 스테이터의 박형화와 아울러 권선공정에서 결선공정에 이르기까지의 공정의 자동화를 도모하고 비용절감을 가능하게 하는 것을 목적으로 한다. 
     본 발명의 회전전기기계의 스테이터는 방사상으로 돌출하는 여러개의 돌극(132), …, (132)을 가지는 스테이터 코어(13)의 링부분에 장착된 절연성의 코어홀더(131)에, 돌극(132)에 권회된 권선(15)의 권회개시단과 권회종료단을 유지하는 유지부(133b)와, 권선(15)의 권회개시단 혹은 권회종료단의 사대측단자부를 접속하는 부위(15a)를 노출시킴과 동시에 이 권선(15)의 권회개시단 및 권회종료단을 대응하는 단자부 예를들면 회로기판의 납땜랜드에 납땜하고 땜납을 수용하는 접속부(133a)를 마련하고, 권선(15)의 권회개시단 혹은 권회종료단을 코어홀더(131)로 유지하여 겹쳐쌓인 방향으로 돌출시키지 않는 상태 그대로 회로기판의 납땜랜드 위에 직접 납땜하도록 하고 있다.
