Abstract: The trench structure part includes a field plate electrode, a first insulating film, a second insulating film, the second insulating film extending to be more proximate to the first surface than the first insulating film, a gate electrode including a first portion located on the second insulating film, and a second portion located on the first insulating film, the second portion being thicker than the first portion, and a third insulating film. The gate contact part extends from the gate wiring layer toward the second portion and contacts the second portion. The gate contact part is not positioned between the first portion and the gate wiring layer. The first portion is positioned adjacent, in a second direction orthogonal to the first direction, to a lower end portion of the gate contact part contacting the second portion.

Abstract: Measurement of 3D displacement based on successively captured images of an object becomes difficult to be performed due to a load imposed on an operator along with an increase of the number of target portions defined on the object and that of time steps for displacement measurement. A device for displacement measurement executes stereo measurement relative to a stereo image to generate 3D shape information and orthographically projected image of an object for each time, and tracks the 2D image of the target portion through pattern matching between orthographically projected images at successive times to obtain a 2D displacement vector. The device for displacement measurement converts the start point and the end point of the 2D displacement vector into 3D coordinates, using the 3D shape information, to obtain a 3D displacement vector.

Abstract: This invention provides a novel structure for forming a suspender to be attached to an article. The suspender 12 is partly adhered to an article 13 to be suspended with an adhesive 14 or the like. The suspender 12 can be stretched in a length direction and is composed of a strip made of plastics film having properties of rarely shrinking after elongation. The suspender is stretched when used.
