Abstract: The invention provides a dental gypsum-bonded investment material powder which can inhibit air bubbles from being generated in a mixed material, only by being mixed with water without using any special device or tool, and is easily mixed with the water. A specific siloxane is blended at a specific amount in relation to the dental gypsum-bonded investment material powder which includes an anionic surfactant and is excellent in a mold releasing action. In other words, the dental gypsum-bonded investment material powder is structured such as to have 0.001 to 0.2 weight % anionic surfactant, and 0.00001 to 0.0005 weight % cyclic siloxane having 3 to 10 SiO(CH3)2 units.

Abstract: A paper sheet processing system has a paper sheet processing apparatus and a paper sheet bundle wrapping apparatus. The paper sheet processing apparatus sends category information of a bundle of 100 paper sheets to the paper sheet bundle wrapping apparatus when discharging the bundle of 100 paper sheets. The paper sheet bundle wrapping apparatus classifies and accumulates the bundle of 100 paper sheets based on the category information when receiving the bundle of 100 paper sheets. The paper sheet bundle wrapping apparatus bands ten bundles of 100 paper sheets as a bundle of 1000 paper sheets. Since the paper sheet bundle wrapping apparatus receives the bundle of 100 paper sheets of different category from the paper sheet processing apparatus and accumulates the bundle of 100 paper sheets for every category to form the bundle of 1000 paper sheets, the usage rate of the paper sheet bundle wrapping apparatus becomes high.

Abstract: A sheet processing apparatus and a sheet take-out apparatus that prevents a sheet conveyed by a take-out portion from hanging-down and falling, when the take-out portion is stopped due to an emergency. If a take-out emergency process state occurs during the take-out of sheets, the sheet take-out apparatus stops upward movement of a backup plate, moves down feed stoppers, and presses a sheet bundle from above to prevent the sheet on the uppermost surface from being taken out. The sheet take-out apparatus also keeps a rotor air valve on and takes out the sheet caught in a sheet take-in port. When residual sheets on the backup plate are later detected, the sheet take-out apparatus moves down the position of the backup plate, turns off air valves for the rotor, fixed absorbing unit, and handling, and loads a hanging-down sheet on the backup plate, to prevent the sheet from scattering.
