Abstract: To assist an operator in setting an observation conditions, so as to acquire an image with a desired image quality (such as contrast) in a charged particle beam device without falling into trial and error based on the experience of the operator. Therefore, the charged particle beam device includes a stage 115 on which a sample is placed, a charged particle optical system configured to irradiate the sample with a charged particle beam, detectors 121 and 122 configured to detect an electron generated by an interaction between the charged particle beam and the sample, a control unit 103 configured to control the stage and the charged particle optical system according to an observation condition set by the operator and configured to form an image based on a detection signal from the detectors, and a display 104 configured to display an observation assist screen for setting the observation condition.

Abstract: According to one embodiment an electronic apparatus includes a housing, a heat generating element, a plurality of sensors, and an index calculator. The heat generating element is housed in the housing. The index calculator calculates an index corresponding to a physical quantity or an index indicating performance of the electronic apparatus, based on a correlation between detected values of the sensors and the index.

Abstract: An electric wire connecting device connects a conductor of an electric wire formed of a plurality of core wires to a terminal. The connecting device includes a pair of clamping members for clamping a part of an end portion of the conductor, and a ultrasonic welding horn for connecting the conductor to the terminal via ultrasonic welding in a state where the end portion of the conductor clamped by the clamping members is placed at the terminal.

Abstract: A structure of an electric wire for connection includes a conductor end portion of the electric wire comprised of a plurality of core wires. The conductor end portion is compressed by press-forming that pressurizes from the side of an outer peripheral surface thereof toward the side of the axis thereof. The conductor end portion is formed with a press-formed surface by the press-forming on an outer peripheral surface thereof, the press-formed surface being a surface that extends in an axial direction of the conductor end portion and being in the shape of steps that come close to the axis of the conductor end portion from a root side of the conductor end portion toward a tip side of the conductor end portion.

Abstract: A structure of an electric wire for connection includes a conductor end portion of the electric wire comprised of a plurality of core wires. The conductor end portion is compressed by press-forming to pressurize from the side of an outer peripheral surface thereof toward the side of the axis thereof. A tapered surface is formed by the press-forming on the outer peripheral surface of at least a tip side of the conductor end portion, which inclines toward a direction crossing an axial direction of the conductor end portion. The conductor end portion on which the tapered surface is formed is electrically connected with a connected portion by ultrasonic joining.

Abstract: A method for producing a fluorene derivative by reacting fluorenone with a phenol or a phenoxyalcohol in the presence of an acid catalyst includes: adding an alkali to an obtained reaction liquid containing a fluorene derivative; and concentrating a resultant mixture liquid without removing the alkali thus added and a reaction product of the alkali, thereby separating an unreacted phenol or unreacted phenoxyalcohol.
