The invention provides an observation system capable of observing a formation position of a target shape that cannot be directly irradiated with an electron beam. The observation system includes an electron microscope and a computer. The electron microscope is configured to irradiate, with an electron beam, a first surface position on a specimen, which is different from a formation position of a target shape on the specimen, detect predetermined electrons that are scattered in the specimen from the first surface position and that escape from the formation position of the target shape to an outside of the specimen, and output the predetermined electrons as a detection signal. The computer is configured to output one or more values related to the target shape based on the detection signal.

A wire for a medical device includes a wire body and a solid lubrication film. The wire body has an outer circumferential layer formed of a plurality of metal strands that are twisted with each other. The solid lubrication film is formed at least on outside exposed surfaces of the plurality of metal strands. When a virtual circle as a smallest circle enclosing the outer circumferential layer is assumed in a cross section perpendicular to a central axis of the wire body, a part of an outer edge of the solid lubrication film of the cross section is inside the virtual circle and a cross-sectional area of the solid lubrication film in the cross section satisfies A/B&#x3e;0.7 where A is a size of a portion outside the virtual circle and B is a size of a portion inside the virtual circle.

The purpose of the present invention is to provide a shape measuring device and method, wherein the separation of light from one distance sensor increases measurement precision without increasing the size of the device. The present invention provides 'a shape measuring device comprising: a distance sensor that radiates a laser toward a measurement target and detects the reflected light so as to calculate the distance to a measurement point; a separation unit that separates the light from the distance sensor into a plurality of light rays; a rotation unit that rotates the distance sensor and the measurement target relative to each other; and a data processing unit that integrates measurement results obtained from the distance sensor for the distances to a plurality of measurement points.'

Shape measuring method and device

The purpose of the present invention is to provide a shape inspection device that improves, without making the device larger, durability and measurement precision by measuring a plurality of points with a single distance sensor. The present invention provides a shape measuring device that measures the shape of an object to be measured and that comprises: a distance sensor that calculates the distance to the object to be measure by irradiating a measurement light toward the object to be measured and detecting the reflected light from the object to be measured; a separating unit that separates the measurement light from the distance sensor into a plurality of measurement light rays to be irradiated onto a plurality of measuring points; and a selecting unit that selects, from the plurality of measurement light beams separated by the separating unit, the measurement light to irradiate the object to be measured.

The present invention improves a method of forming a surface unevenness using a difference in etching rates, and relaxes limitations on substrates in this method. In a method of the present invention, an uneven surface is formed by a method including applying pressure to a predetermined region in a surface of a thin film formed on a substrate, and etching a region including at least a portion of the predetermined region and at least a portion of the reminder of the surface that excludes the predetermined region. An etching rate difference within the thin film increases freedom in selecting a substrate material.

An apparatus for preventing a vibration of an elevator tail-line having one stationarily held end and an opposite end connected to an elevator carriage to move together therewith. An absorber absorbs the vibration of the elevator tail-line, and a supporter bears a weight of the elevator tail-line to prevent the weight of the elevator tail-line from being applied to the absorber so that the absorber does not bear the weight of the elevator tail-line.
