A method of sample analysis is offered which provides improved quantitative accuracy. This method starts with irradiating a sample with an electron beam. Characteristic X-rays emanating from the sample are detected. Plural data sets about intensities of characteristic X-rays corresponding to a specific element contained in the sample are obtained. The element is quantitatively analyzed based on the plural data sets. This method includes a step (S) for calculating quantitative values for the element for the plural data sets, respectively, about the characteristic X-ray intensities, a step (S) for calculating weights for the quantitative values, respectively, based on the plural data sets about the characteristic X-ray intensities, and a step (S) for calculating a weighted average of the quantitative values based on the weights.

The present disclosure provides a power conversion apparatus and an initial charging method of the same to control a closing phase angle at the time of switching on a power source, to suppress an overvoltage of a DC voltage, and to prevent overcharge and breakage of parts caused by the overvoltage. A peak voltage value of an input voltage, a total secondary side converted winding resistance of a primary side and a secondary side of an input transformer, a total leakage inductance of the primary side and the secondary side of the input transformer, a capacitor, and a power source frequency are substituted in a mathematical expression, and a closing phase angle is varied at predetermined intervals to obtain first half-wave peak voltage values of the capacitor voltage at the closing phase angles to close a circuit breaker.

A license administration device manages grant or denial of each optional function in a plurality of licensee devices. The licensee device stores key information encrypted with a cipher key so as to issue a license change request activating or restricting the predetermined optional function. Upon receiving a license change request restricting the predetermined optional function, the license administration device overwrites the key information of the licensee device with a default key. Subsequently, upon receiving a license change request activating the predetermined optional function, the license administration device applies an upgrade key to the key information of the licensee device. The default key or the upgrade key can be decrypted using a cipher key unique to the licensee device. The license administration device manages the licensed maximum for the predetermined optional function and reflects an increment or decrement to the licensing maximum by applying the default key or the upgrade key.

A license management device causes a wireless device to enter a state in which all functions are restricted by overwriting key information of the wireless device with a default key specific to the wireless device. A key generating device generates an upgrade key specific to the wireless device, and transmits the update key to the license management device. The license management device can release a restriction of a function in the wireless device by applying the upgrade key to the key information of the wireless device overwritten with the default key.

A sample analyzer is offered which creates a ternary scatter diagram representing a concentration ratio distribution of three elements out of several elements to be analyzed. This three-dimensional graph is created by adding an axis to the ternary scatter diagram and representing concentration information about the two additional elements on the added axis. The sample analyzer performs elemental analysis of a sample by scanning a primary beam over the sample and detecting a signal emanating from the sample. The added axis intersects the plane of the ternary scatter diagram.

A tag device causes a second calculator to read a confidential value from a confidential value memory and to apply a second function Fwhich disturbs a relationship between elements of a definition domain and a mapping thereof to generate tag output information. The tag device delivers the tag output information to a backend apparatus. Subsequently, a first calculator reads out at least part of elements of the confidential value from the confidential value memory, and applies a first function F, an inverse image of which is difficult to obtain, and a result of such calculation is used to update a confidential value in the confidential value memory by overwriting.

A recipient identifier and communication condition information stored in a recipient-identifier storing unit are encrypted by an identifier-for-disclosure creating unit of a recipient terminal to create an identifier-for-disclosure. An identifier-for-disclosure notifying unit notifies a sender terminal of the identifier-for-disclosure. When a communication request using the identifier-for-disclosure is sent from the recipient terminal, a restoring unit of a relay system extracts the communication condition information from the identifier-for-disclosure. Only when communication conditions included in the communication condition information are satisfied, communication between the recipient terminal and the sender terminal is established.
