Publication number: 20230026069Abstract: A pressure-sensitive adhesive sheet capable of allowing a small electronic part to be temporarily fixed in a satisfactory manner and satisfactorily peeled. The pressure-sensitive adhesive sheet includes: a gas-generating layer; and a gas barrier layer arranged on at least one side of the gas-generating layer, wherein the gas barrier layer is a layer that is deformed through laser light irradiation of the pressure-sensitive adhesive sheet, wherein a thickness (?m) of a highly elastic portion of the gas barrier layer is equal to or smaller than a value calculated by the following expression (1), and wherein the thickness (?m) of the highly elastic portion of the gas barrier layer is equal to or larger than a value calculated by the following expression (2): 12546×EXP(?0.728×log10(Er×106)) . . . (1); 18096×EXP(?0.949×log10(Er×106)) . . . (2), where Er represents a modulus of elasticity (MPa) of the highly elastic portion of the gas barrier layer by a nanoindentation method at 25° C.Type: ApplicationFiled: November 30, 2020Publication date: January 26, 2023Applicant: NITTO DENKO CORPORATIONInventors: Shusaku UENO, Takamasa HIRAYAMA

Patent number: 10000262Abstract: A terminal device stores ship characteristic data that indicates a relationship between rotation speed and ship speed, and rotation speed and fuel consumption when a ship is navigated under various navigation conditions. If a user inputs data that indicates draft state and wind and wave state on a performance display screen displayed on the terminal device, the terminal device generates relationship data that indicates a relationship between rotation speed and ship speed, and rotation speed and fuel consumption when a ship is navigated under wind and wave states corresponding to the input data and each of a plurality of Beaufort states that are set in the terminal device in advance on the basis of the ship characteristic data. The terminal device displays a graph that displays the relationship between rotation speed, ship speed and fuel consumption for each of a plurality of navigation conditions using the relationship data.Type: GrantFiled: September 27, 2013Date of Patent: June 19, 2018Assignee: Nippon Yusen Kabushiki KaishaInventors: Hideyuki Ando, Shusaku Ueno
