Abstract: PURPOSE: To prevent a change in black reference level due to a light blocking pixel by forming a potential barrier. CONSTITUTION: Sources or drains 14 of transistors, and photodiodes 13 which constitute light blocking pixel covered by a light blocking layer 16 are formed in a surface of a highly doped well 20 formed in a lightly doped substrate 11, forming the potential barrier ΔV from the lightly doped substrate 11 toward the heavily doped well 20. Even if spot light of a strong intensity is incident into part of a light receiving pixel, causing part of light 17 to reach a neutral region of the lightly doped substrate 11, part of diffused charges 18 which have been subjected to photoelectric transfer in there are prevented from entering the heavily doped well 20 because there is the potential barrier. Consequently, an output signal level of the light blocking pixel never changes, resulting in keeping the black reference level as it is.

Abstract: 본 발명은 승용자동차의 타이어공기압력자동 가변장치에 관한 것으로서  자동차의 타이어 공기압력 상태가 자동차 운행이나운전과 그 성능에 큰 영향을  주게 된다는 점은 운전 경험자들의 일반적인 상식이다. 승용자동차의 타이어 공기압력을 한 예로서 자동차 제조회사에서 지정한 2.25㎏/㎤ 인 중형자동차의 경우를 검토하여 보면 사용자의 취향에 의하여 경쾌한 운전성과 연비향상등을 고려하여 타이어압력을 2.46㎏/㎤ 이상으로 높여서 사용하는 경우를 흔히 볼 수 있다. 이 경우에는 우선 승차감에 있어서 진동이 심하여 고속도로 같은 잘 포장된 노면이외에서는 견디기 어려운 불쾌한 승차감을 겪어야 할 것이다. 또한 안정성에 있어서도 고속주행시 코너링(Cornering)이 불안하고 습기있는 노면에서는 미끄럼현상도 발생된다. 한편 승차감을 중요시하는 사용자의경우를 보면 타이어 공기압력을 1.96㎏/㎤ 이하로 운행들을 하게된다. 이 경우에는 승차감은 확실히 향상되고 미끄럼등에 대한 안전성 또한 크게 개선된다. 그러나 운전에서 자동차의 운동성이 둔해지고 연비도 크게 떨어지는 결점이 있다. 본 발명에서는 이상과 같은 결점을 해결하기 위하여 승용자동차의 타이어 공기압력을 적절하게 가변(Variable)장치로 변화시켜서 항상 만족한 상태의 운전을 유지시키고자  하는데 있다.
