摘要:
A photosensitive material and comprises a photosensitive and heat-developable element and a polymer, and is capable of being endowed with stickness by a change of pH value or being subjected to exposure and heating. An image formation process comprises the steps of subjecting to imagewise exposure the photosensitive material, heating the photosensitive material, electrifying the photosensitive material, and transferring the iamgewise exposed or unexposed portion of the photosensitive material. The photosensitive and heat-developable element comprises a least a photosensitive silver salt and a reducing agent and the polymer has a cross-linked structure.
摘要:
A printing process using an ink which is substantially non-adhesive but can be imparted with an adhesiveness when subjected to a pH change. In the printing process, the ink is subjected to a pH change to be provided with an adhesiveness to a desired depth, and the resultant adhesive ink is supplied to a printing plate having a pattern of ink receptibility to form thereon an ink pattern corresponding to the ink receptibility pattern. The ink pattern is then transferred to a transfer-receiving medium such as plain paper to form thereon a recorded image. In the above-mentioned printing process, a uniform thin ink layer can be supplied to the printing plate by chemically regulating the amount of the ink to be supplied.

A method of producing surface-treated barium sulfate is disclosed which has an improved dispersibility in resins and coating compositions. The method comprises adding an aqueous solution of an alkali silicate to an aqueous slurry of barium sulfate which contains barium ion in excess to deposit barium silicate on the surface of barium sulfate, and then adding to the slurry a mineral acid to decompose the barium silicate to hydrous silica. The thus surface-treated barium sulfate may be further coated with hydrous metal oxides such as alumina or with a silane coupling agent so as to have a more improved dispersibility.

An upper sealing ring and a lower sealing ring are adhered by sealing solder. The width of tip end of sealing projection is narrower than the width of the lower sealing ring. Therefore, the sealing solder is placed on lower sealing ring and on the side surface of upper sealing ring. Further, an upper connection pad and a lower connection pad are adhered by connecting solder. The width of a tip end of a connection projection is narrower than the width of lower connection pad. Therefore, the connecting solder is placed on the lower connection pad and on the side surface of upper connection pad. Thus, a package is provided, which attains satisfactory electrical connection and hermetic seal after solder joint of the upper and lower substrates.

A sheet stack cutter cuts sheet stacks by means of a moving cutter edge and a stationary cutter edge disposed upward and downward along a predetermined cutting-plane line. The sheet stack cutter includes a sheet loading table for supporting the sheet stack, a press device for pressing and holding the sheet stack on the sheet loading table, a moving cutter edge disposed in up and down cutting directions for cutting the sheet stack on the sheet loading table along the cutting-plane line, a stationary cutter edge disposed to the side of the sheet loading table for pressing the moving cutter edge to cut the sheet stack, and an apparatus frame furnished with the press device and the moving cutter edge. A drive device moves the moving cutter edge in up and down cutting directions.
