摘要:
An active matrix cell includes a first conductor group formed on a transparent substrate, two-layered regions consisting of a semiconductor film and a first insulating film, a second insulating film and a second conductor group. The first conductor group forms the source and drain of a thin film transistor, pixel electrode, data line. One of the two-layered regions serves as an active region of the thin film transistor and the other of the two-layered regions serves as the intersection between the data and scanning lines. The second insulating film is buried in the gap between the two-layered regions and the first conductor group, and has substantially a same thickness as the two-layered regions. The second conductor group forms the scanning line and the part of the data line. A method of manufacturing the active matrix cell is also disclosed.
摘要:
An apparatus for controlling idling revolution speed of an internal combustion engine in which air at an upstream side of a throttle valve of an intake tube of the internal combustion engine is injected nearby a fuel injection valve from an injection port provided in an intake manifold of the internal combustion engine through a bypass passage and a flow rate control device. The flow rate control device is provided with a valve housing and a valve seat retaining member having a cylindrical wall disposed within the valve housing and a valve body which is moved forwardly and backwardly by a stepping motor is seated on a valve seat. A flow space is formed between the valve seat and an outlet port provided in the valve housing for communicating thereof with the injection port. The flow space includes an annular or semi-annular space formed between the valve housing and the valve seat retaining member and provides a long folded air flow passage to remove oil mist and dust from the air flowing toward the injection port.
