A liquid drop discharge device provides a head unit 420 which discharges filter element material relative to each of various colors of color filters. The head unit 420 is composed of an ink jet heads which are arranged on one end of a print substrate plate having a shape of rectangular card and head devices 433 which are arranged on the other end of the print substrate plate comprising connectors 441. The head devices 433 are aligned in two rows, as two groups, in a staggered arrangement so that a portion on which the connectors 441 are aligned in one of the two rows does not face to the same portion of the other in the two rows and protrudes outside of the print substrate plate. The head unit 420 discharges the filter element material onto predetermined portions in a superimposing manner while shifting along a direction which intersects to a direction along which the head devices 433 are arranged.

A semiconductor device comprises: a p-type semiconductor substrate (1); an insulating film (3); a gate electrode (2) formed on the substrate via the insulating film; and an n-type source/drain region (5) formed on both sides of a channel forming region (4) located under the gate electrode (2) formed on the substrate (1). In particular, the thickness (TOX) of the insulating film (3) is determined to be less than 2.5 nm at conversion rate of silicon oxide film (silicon oxide equivalent thickness); a gate length (Lg) of the gate electrode (2) is determined to be equal to or less than 0.3 &mgr;m; and further a voltage applied to the gate electrode (2) and the drain region (6) is determined to be 1.5 V or less. Therefore, in the MOSFET having the tunneling gate oxide film (3), the reliability of the transistor under the hot carrier stress can be improved, and the gate leakage current can be reduced markedly, so that the transistor characteristics can be improved markedly.

According to a waste water treatment method and apparatus of the present invention, a permeable sheet 3 is fed into a treatment tank 2 in which a stream is formed. The waste water, which flows downstream, is caused to pass through the permeable sheet 3, while the permeable sheet 3 travels in the treatment tank 2 so as to traverse the surface of the waste water on a downstream side in the flowing direction of the waste water. Therefore, not only the sludge in the waste water but also the oily substances floating in the waste water can be collected and removed because they cling to the permeable sheet 3 and are gathered by it. As a result, a waste water treatment tank 2 and the like can be maintained in a usable state for a long time. In addition, there can be obtained a treated water to which microbial treatment can be applied.

In floating substance removing, collecting and treating method and apparatus capable of securely separating and collecting floating substances floating on a water surface without adversely affecting an ecological system regardless of the type and state of the floating substances, a permeable sheet 4 is successively or intermittently moved through a drive unit 5 so as to traverse the treating water P taken from an intake port 3 and at the same time the treating water P is forcibly moved relatively to the permeable sheet 4. Accordingly, floating substances F on the water surface can be effectively collected by being deposited on and separated from the permeable sheet 4, whereby filtered clean water can be obtained.
摘要:
A liquid crystal device is constituted by a chiral smectic liquid crystal and a pair of substrates sandwiching the chiral smectic liquid crystal therebetween and each having thereon an electrode for applying a voltage to the liquid crystal. At least one of the substrates being provided with an alignment control film comprising a specific aromatic polyimide which has been subjected to a uniaxial aligning treatment. The chiral smectic liquid crystal assumes bistability in a chiral smectic temperature range when incorporated in a test cell which is not provided with an alignment control film and has been subjected to shearing treatment. In the liquid crystal device including the polyimide alignment control film, the chiral smectic liquid crystal at least has a voltage-transmittance characteristic such that an effective tilt angle and a transmittance continuously change depending on an electric field applied thereto.
