Title: Field emission type display and its manufacture
Inventor: SEN IHAN
IPC: H01J9/02
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent such trouble with spacer members for a field emission type display that the spacer members are often scattered onto electron-emitting elements when glass beads are used, because the scattering positions of the spacer members are hard to control accurately, and if a fluorescent substrate overlaps on a FEA(field emitter array) substrate in such a state, some of the electron-emitting elements are destroyed to cause black points in a display. SOLUTION: An electron-emitting element array substrate 4 on which field emission type electron-emitting elements are arranged in an arrayed state face opposite a fluorescent substrate 8 to emit fluorescence with the injection of electrons, emitted from the electron-emitting elements to form this display. In this case, in order not to put both substrates in mutual contact, spacer members 9A, 9B formed by an overlapping and embedding method are provided on the electron-emitting element array substrate 4 or on the fluorescent substrate 8.

Title: Production of substrate for photographic paper
Inventor: KITAGAWA KEIJI
IPC: D21H27/30
Filed: 1981-12-03
Abstract: PURPOSE:To prevent the contamination of cut surfaces in the stage of extrusion coating of molten polyolefin by specifying the temp. of cooling rolls. CONSTITUTION:After molten polyolefin is coated on both sides of base paper, the surface temp. of cooling rolls for the purpose of cooling and solidifying is set in a 35-100 deg.C range. Heretofore, the substrate for photographic paper is manufactured by controlling the surface temp. in an about 10-32 deg.C range in order to improve productivity, but if such substrate is cut, the paper receives shearing forces between the upper and lower knives of a cutter and is cut in the form that the polyolefin coating layers are stretched, which is unsightly and is more significant on the side where no emulsions are coated. Cutting quality is improved if the surface temp. is controlled in said range, more preferably at 40-90 deg.C.
