A service providing system includes an information processing system including an information processing apparatus including a memory and a processor; and a terminal device configured to receive execution of an application. The information processing system and the terminal device communicate with each other. The processor of the information processing apparatus is configured to execute storing information on the application of which a user has a license, and controlling a function of a first application depending on whether the user who requested execution of the first application via the terminal device, has a license of a second application.

A charged-particle beam instrument is offered which can cancel out deflection aberrations arising from a first deflector or oblique incidence on the surface of a workpiece without (i) increasing the electrode length, (ii) reducing the inside diameter of the electrode, or (iii) increasing the deflection voltage too much. The instrument has an electron source for producing an electron beam, a demagnifying lens for condensing the beam, an objective lens for focusing the condensed beam onto the surface of the workpiece, the first deflector located behind the demagnifying lens, and a second deflector located ahead of the demagnifying lens. The first deflector determines the beam position on the surface of the workpiece. The second deflector cancels out deflection aberrations arising from the first deflector.

An FRP is produced using a prepreg comprising reinforcing fiber, a sheet-like reinforcing fiber substrate containing reinforcing fiber, and a matrix resin, wherein the matrix resin is impregnated into the sheet-like reinforcing fiber substrate and also covers one surface of the sheet-like reinforcing fiber substrate, and the matrix resin impregnation ratio is within a range of 35% to 95%; a prepreg comprising reinforcing fiber, a sheet-like reinforcing fiber substrate containing reinforcing fiber, and a matrix resin, wherein the matrix resin exists on both surfaces of the sheet-like reinforcing fiber substrate, and the portion inside the sheet-like reinforcing fiber substrate into which the matrix resin has not been impregnated is continuous; or a prepreg comprising reinforcing fiber, a sheet-like reinforcing fiber substrate containing reinforcing fiber, and a matrix resin, wherein at least one surface exhibits a sea-and-island-type pattern comprising resin-impregnated portions (island portions) where the matrix resin is present at the surface and fiber portions (sea portions) where the matrix resin is not present at the surface, the surface coverage ratio of the matrix resin on those surfaces with said a sea-and-island-type pattern is within a range of 3% to 80%, and the weave intersection coverage ratio for the island portions, represented by a formula (1) shown below, is at least 40%, displays excellent external appearance, with no internal voids or surface pinholes, even when molded is conducted using only vacuum pressure. Island portions weave intersection coverage ratio (%)=(T/Y)×100 (1) (wherein, T represents a number of island portions that cover weave intersections, and Y represents a number of weave intersections within said reinforcing fiber woven fabric on said surface with said sea-and-island-type pattern).

A drilling control apparatus for automatically controlling the drilling operation of a rock drill includes a control unit for storing known criteria drilling patterns for various rock properties. A specific drilling pattern is selected based upon a collaring procedure for operation of the rock drill. A detector continually monitors variables such as rotational pressure, feed pressure and flushing pressure during the drilling process to determine a change in condition of the rock for determination of automatic selection of another more appropriate drilling pattern.

Disclosed is a method for recovering carbon dioxide from a gas containing carbon dioxide, comprising the step (1) of bringing a gas containing carbon dioxide into contact with an aqueous solution containing 2-isopropylaminoethanol and at least one substance selected from the group consisting of piperazines and alkanolamines to absorb carbon dioxide into the aqueous solution; and the step (2) of heating the aqueous solution containing carbon dioxide absorbed therein, which is obtained in the step (1), to separate and recover carbon dioxide from the solution.
摘要:
A method of calibrating the beam position in a charged-particle beam system starts with finding a focus deviation on the material surface for each point within a deflection field. A focus correction voltage VF necessary to cancel out the focus deviation is determined. A beam position deviation fi per unit focus correction voltage is found. The deflection voltage is corrected so as to cancel out the product fi·VF. The deflection voltage is corrected so as to cancel out the sum of the product fi·VF and the measured deflection field distortion while correcting the focus based on the voltage VF.

A charged-particle beam system has a demagnifying lens for reducing the dimensions of an electron beam produced from an electron beam source, an objective lens for focusing the demagnified beam onto the surface of a target, a first deflector located before the demagnifying lens, a second deflector placed such that the deflection field produced by it is totally or partially superimposed on the objective lens field, and a third deflector located in a stage following the second deflector. An image of the light source is created by the demagnifying lens. An image of the light source image is formed on the target by the objective lens.

摘要:
There is disclosed an electrostatic deflector having four pillar-like identical electrodes spaced from each other by 90°. An even number of pillar-like electrodes are disposed in each space between the four electrodes. Spaces are formed on both sides of each one of the first electrodes and have bent portions. The even number of electrodes are arranged symmetrically relative to a third or fourth vertical plane including an axis spaced from the X-axis by 45° or −45°, respectively. Holes are formed across each of the third and fourth vertical planes. Rod-like members are inserted in the holes.
