The present invention provides a material for an antireflective film characterized by high etching selectivity with respect to a resist, that is, which has a fast etching speed when compared to the resist, and in addition, can be removed without damage to a film which is to be processed. The present invention also provides a pattern formation method for forming an antireflective film layer on a substrate using this antireflective film-forming composition, and a pattern formation method that uses this antireflective film as a hard mask, and a pattern formation method that uses this antireflective film as a hard mask for processing the substrate. The present invention provides an antireflective film-forming composition comprising an organic solvent, a cross linking agent, and a polymer comprising a light absorbing group obtained by hydrolyzing and condensing more than one type of silicon compound, a crosslinking group and a non-crosslinking group.

To provide a light-emitting device having an airtight container sealed at a lower temperature by means of a sealing material not containing a harmful component such as lead, which is free from heat deterioration of a phosphor, particularly a blue-emitting phosphor. A light-emitting device having an airtight container sealed by means of a sealing composition comprising a curable methylphenyl silicone resin and a refractory filler, wherein the amount of the refractory filler based on the sum of the methylphenyl silicone resin and the refractory filler in the sealing composition, is from 10 to 80 mass %, and the methylphenyl silicone resin has a molar ratio of phenyl groups to methyl groups (i.e. mols of phenyl groups/mols of methyl groups) of from 0.1 to 1.2.

In exhaust gas purification system (10) including catalyst unit (50) carrying a NOx occlusion-reduction type catalyst, a first-stage rich control having a target air-fuel ratio lower than theoretical air-fuel ratio is conducted through addition of the amount of reducing agent meeting the amount of oxygen emitted in the initial stage of regeneration control. In the first-stage rich control, the completion of oxygen emission is judged on the basis of the oxygen concentration on the downstream side of catalyst unit (50). Upon determination of the completion of oxygen emission, a later-stage rich control close to the theoretical air-fuel ratio with the target air-fuel ratio increased over that of the first-stage rich control is carried out to thereby accomplish regeneration of the catalyst unit (50). As a result, during the regeneration control of the catalyst unit (50), there can be prevented not only any outflow of unpurified NOx occurring in the initial stage of regeneration but also any outflow of virgin reducing agents, such as HC and CO, occurring in the later stage of regeneration.

The collecting bag is intended for human body wastes and has a bag member (1) and a discharge portion (8) including a discharge opening (9). The bag member (1) and the discharge portion (8) are formed by a first and a second film blank (2, 3). A first plate member (21) is positioned on the first film blank (2) and a second plate member (22) is positioned on an extension (3e) of the second film blank (3) such that the plate members have a distance (d) between them. Two strap members (23, 24) are positioned between the first and the second plate member (21, 22).

An image forming apparatus includes a recording sheet storage unit for storing recording sheets substantially in an upright position, an image forming unit which forms an image on a recording sheet conveyed from the recording sheet storage unit, and a recording sheet receiving unit for storing the recording sheet conveyed from the image forming unit substantially in an upright position. In this image forming apparatus, a paper conveyance passage for conveying the recording sheet extends upward from a lower portion of the recording sheet storage unit toward the recording sheet receiving unit. The image forming unit positioned on the paper conveyance passage comprises a fixing device and a developer unit at least including a developer carrier, and the fixing device is arranged above the developer unit.

The collecting bag is intended for human body wastes and has a bag member (1) and a discharge portion (8) including a discharge opening (9). A first plate member (21) is positioned on a first film blank (2) forming part of the bag and a second plate member (22) is positioned on an extension (3e) of a second film blank (3) forming part of the bag. At least one of the edges (21b, 22a) of the plate members (21, 22) is provided with a fillet or chamfer (21c, 22c).
