摘要： A polishing pad (1) is provided with higher polishing efficiency for polishing an outer circumferential edge part (3d, 3e) of a disc-shaped wafer (3). An unpolished part is less likely to occur during a polishing process with the polishing pad (1), and the polished wafer (3) is cleanable easily. In the polishing pad (1), a polishing surface is formed of a polishing body, and the polishing body includes a base material and polishing particles. The base material is composed of a binder resin and fibers and has a plurality of pores formed therein. The polishing particles are retained in the base material or in the pores and are diamond particles. The polishing pad (1) has a durometer hardness in a range from 16 to 27, a density in a range from 0.58 to 0.81 g/cm3, and an elastic modulus in a range from 21.5 to 37.5 N/mm2.

摘要： The present disclosure provides a technology of obtaining a ceramic product including a decorative film which has a sufficient chemical resistance and can reduce damage during cleaning. A decorative composition disclosed herein contains at least a noble metal element and a glass matrix element. The glass matrix element contains a rare-earth element and a first element which is at least one selected from the group consisting of Si and Al. In the decorative composition disclosed herein, the content of the rare-earth element in the glass matrix element is from 1 mol % to 45 mol % inclusive, and the content of the first element in the glass matrix element is from 50 mol % to 90 mol % inclusive. This allows the decorative film having both alkali resistance and acid resistance at high level to be formed.

摘要： A method for producing a high-porosity vitrified grinding stone that has a plurality of pores communicating with each other. The method includes: (a) a grinding-stone-material preparing step of obtaining a grinding-stone raw material slurry that is a mixture fluid of abrasive grains, a vitrified bond, a gellable water-soluble polymer and a water; (b) a molding step of obtaining a molded body, by gelling the grinding-stone raw material slurry with use of a molding mold; (c) a freeze vacuum drying step of generating a plurality of frozen particles inside the molded body by freezing the molded body, and placing the molded body under a vacuum state, so as to sublimate the frozen particles generated inside the molded body for thereby drying the molded body; and (d) a firing step of obtaining the high-porosity vitrified grinding stone, by binding the abrasive grains with the vitrified bond by firing the molded body.

摘要： A touch panel is formed by laminating: a glass substrate having a touch surface; an X-axis sensor unit having parallel patterns, each of which having diamond-shaped X-axis lattices 10A and 10B aligned in an X-axis direction; an Y-axis sensor unit having parallel patterns each of which having Y-axis lattices 14A and 14B aligned in a Y-axis direction; and an insulation layer arranged between the X-axis sensor unit and the Y-axis sensor unit. The X-axis lattices and the Y-axis lattices are not overlapped when seen from a side of the touch surface. A gap 17 is formed between a frame line 10a of the X-axis lattice and a frame line 14a of the Y-axis lattice. A protrusion part 12 extended parallel to a lattice side of a fine lattice from the frame line 10a of the X-axis lattices 10A and 10B is arranged in the gap 17.

摘要： The present invention provides an inkjet ink for a ceramic substrate, the inkjet ink making it possible to prevent a printed layer from peeling away after firing and allowing a desired image to be better fixed on a ceramic substrate. In the inkjet ink for a ceramic substrate disclosed here, the proportion of a monofunctional monomer in a monomer component is at least 90 mass %, the volume ratio of an inorganic solid relative to the total volume of the inkjet ink is 10 vol % to 20 vol %, and the ratio of the content of an N-vinyl compound to that of the monomer component (N-vinyl compound/monomer component) in the inkjet ink is 0.05 to 0.8 in terms of mass.
