A sheet feeding device includes a stacking plate, a moving mechanism, a pick-up device, a detection plate, a detecting device, and a control section. The stacking plate is movably supported inside the sheet feeding device. The mechanism moves the stacking plate up and down. The pick-up device sends a top one of sheets stacked on the stacking plate, out in a direction from a sheet feeding position within a predetermined level range. The detection plate is mounted above the position and below a top inner surface of the sheet feeding device, with a lower surface thereof facing an object to be placed on the stacking plate. The detection plate is movably supported at a support portion provided at a predetermined location in an upper surface thereof. The detecting device detects upward and downward displacement of the detection plate. According to the detection result, the section controls operation of the mechanism.

The present invention relates to an amorphous silica-based coating film with a low specific dielectric constant of 2.5 or below and the Young's modulus of 6.0 GPa or more and having excellent hydrophobic property, and to a method of forming the same. A liquid composition containing a silicon compound obtained by hydrolyzing tetraalkyl ortho silicate (TAOS) and specific alkoxysilane (AS) in the presence of tetraalkyl ammonium hydroxide (TAAOH) is prepared. The liquid composition is then applied on a substrate, heated and cured to obtain a coating film. The coating film obtained as described has a smooth surface and also has specific micropores therein.

A rear structure of a gaseous fuel vehicle in this invention includes right and left rear frame members, and a support frame mounted to the right and left rear frame members, on which support frame a gaseous fuel tank is mounted. Each of the right and left rear frame members is constituted by a curved member which includes a curved portion curving upward, and a front linear portion and a rear linear portion which are lower than the highest portion of the curved portion. The support frame is attached to the front linear portions and the rear linear portions. The front linear portions are attached to the rear end of a vehicle frame to provide a low floor in a passenger compartment. A load applied to the rear ends of the right and left rear frame members is dispersed into the right and left rear frame members and the support frame, and transmitted to the vehicle frame.

Silica particles for polishing have a three-dimensional polycondensation structure with an average particle diameter in a range from 5 to 300 nm. The silica particles have residual alkoxy groups therein and a carbon content in a range from 0.5 to 5 weight % retained in the residual alkoxy groups.
摘要:
A movable sheet separating unit is pushed all the time by a lifting spring in a direction toward a feeding roller. In a non-feeding state, a sheet lifting plate is engaged with an operating fraction so that the movable sheet separating unit is held in a standby position where a separating pad is separated from the feeding roller. In a feeding state, the sheet lifting plate rises and disengages from the operating fraction so that the movable sheets separating unit moves to a pressing position where the separating pad is pressed against the feeding roller. In the pressing position, the separating pad is pressed against the feeding roller via a rotatable support base by a pressing spring, and is displaced by rotation in a direction away from the feeding roller in accordance with a thickness of a sheet S passing through between the separating pad and the feeding roller. Thus, durability of the separating pad can be improved, and a feeder suitable for a fixing type feeding cassette can be provided.

摘要:
The present invention provides a method of forming on a substrate a particle layer highly adherent to the substrate, which comprises the steps of spreading a dispersion (I) comprising a dispersing medium and, dispersed therein, solid particles being surface treated with a compound acting as a binder on a liquid (II) having a specific gravity higher than that of the dispersing medium, said liquid (II) being immiscible with the dispersing medium, subsequently removing the dispersing medium from the dispersion (I) to thereby arrange the solid particles on the liquid (II) so that a particle layer is formed on the liquid (II) and thereafter transferring the particle layer onto a substrate. Moreover, the present invention provides a method of planarizing an irregular surface of a substrate, which comprises transferring the above particle layer to an irregular surface of a substrate and removing parts of the particle layer formed on protrudent parts of the substrate to thereby planarize the irregular surface of the substrate and also provides a particle-layer-formed substrate comprising a substrate and, superimposed on a surface thereof, the particle layer obtained by each of the above methods.
