Abstract: In a system comprising a data processing unit and at least one output device, the data processing unit extracts from output information prepared by an application program media resource information needed in outputting the output information from the output device. The data processing unit reads needed media resource information from media resource storage on the basis of the extracted information, downloads the read media resource information into the output device and then outputs the output information to the output device to initiate an outputting process.

Abstract: A process for producing an aqueous resin dispersion is disclosed, which comprises dissolving a macromonomer having a radical polymerizable group at the terminal thereof and an oil-soluble radical polymerization initiator in a hydrophobic vinyl monomer copolymerizable with the macromonomer to form a solution, emulsifying the solution in an aqueous medium in the presence of an emulsifying agent selected from (A) an alkali sulfosuccinate anionic surfactant and (B) a surfactant comprising from 2 to 98% by weight of (i) an alkali sulfonate anionic surfactant other than (A) or (ii) an alkali sulfuric ester anionic surfactant, and from 98 to 2% by weight of a nonionic surfactant having an HLB value of 10 or more, and copolymerizing the macromonomer and the vinyl monomer at an elevated temperature. The aqueous resin dispersion has a high content of a graft polymer with a reduced content of unreacted macromonomer.

Abstract: A projection optical apparatus used for projecting a pattern in the photolithographic operation for semiconductor device fabrication and a photographic mask used with the apparatus. In the projection optical apparatus, the reflected light from the pattern of a mask is utilized in place of the transmitted light through the pattern of the mask for the purpose of projecting the pattern. For this purpose, the projection optical apparatus includes illuminating optical means for projecting an illuminating light to the pattern of the mask and light guide means for directing the illuminating light reflected by the pattern of the mask to a projection optical system. A mask adapted for use with the apparatus contains a pattern composed of two opaque areas which are different in reflectance from each other.

Abstract: The invention provides a color image pickup device in which image light from a white object to be photographed or image light integrated by a diffusion plate or the like is incident on a pickup tube through an electrochromic element. Two primary color signals are separated from a video signal from the pickup tube, a voltage corresponding to a difference between the two primary color signals is detected by a differential amplifier, and the voltage is then applied across an electrochromic element. A spectral transmittance of which is then controlled, thereby achieving an optimal white balance.

Abstract: A television camera equipped with an active filter section capable of producing dynamic special effects in the picture. The filter section of the camera includes an electro-optic light control device which is arranged in the optical path of the imaging optical section of the television camera such that its light transmittance for the incident light to the image screen of the camera is varied in response to the application of an electric signal, and the variable transmittance area is divided into a plurality of sections adapted to be controlled and drived selectively.

Abstract: This invention provides a commercially advantageous process for producing a foamed article of an aromatic polyester, especially a large-sized foamed article of aromatic polyester having a high expansion ratio. The process comprises mixing an aromatic polyester, a polyepoxy compound, a compound of a metal of Group Ia, IIa or IIIa of the periodic table and a blowing agent in a melt extrusion molding machine optionally with a fibrous filler while introducing the blowing agent thereinto under pressure, extruding the molten mixture from the molding machine, further expanding the foamed unsolidified extrudate in an atmosphere maintained at reduced pressure, and solidifying it by cooling in an atmosphere maintained at reduced pressure. The resulting aromatic polyester foamed article has numerous fine cells having uniform volumes, shapes and distribution.
