Abstract:
A semiconductor substrate has a major surface, another major surface on the opposite side of the first major surface, a strain gauge stripe formed in the central portion of the second major surface by diffusing an impurity therein, and electrodes connected to the strain gauge stripes. These strain gauge stripes are spaced from the peripheral edge of the second major surface by a distance greater than 1/3 of the length of the same major surface. The first major surface of the semiconductor substrate is bonded to an elastic metal load plate.

Abstract:
A stimulus is presented at a predetermined position of a visual field coordinate system set on a visual field dome (118). When measuring the visual field of an eye under examination, quantitative information of a three-dimensional retinal layer structure is acquired that is obtained by means for detecting a range of disappearance of a peak in the reflectance distribution of the retina obtained by a retinal OCT scan. The position of the fovea of the fundus is identified from the three-dimensional retinal layer structure. From the positional relationship with the identified fovea, it is identified to which position in a two-dimensional fundus image the range of disappearance of the peak corresponds. The position corresponding to the range where the peak disappears is marked on the two-dimensional fundus image, and the marked region is detected. A visual field examination region including visual field examination points to be presented on the visual field dome is generated on the basis of the position of the marked region. The visual field examination points in the visual field examination region are presented to the subject using the visual field dome to perform a visual field examination for the eye under examination.

A method includes extracting a first vector used to code a specific block belonging to a coded field picture arranged chronologically adjacent to a field picture to be coded and to a block to be coded, generating a second vector by scaling the first vector based on a temporal distance between the field picture and a second picture specified by a reference index and referenced for the block and included in the field picture and a temporal distance between a first picture pointed by the first vector and the coded field picture arranged chronologically adjacent to the field picture, and correcting the second vector based on a parity of the field picture, a parity of the first picture, a parity of the second picture and a parity of the coded field picture and forming the corrected second vector.
Abstract:
A perimeter performs a kinetic visual field examination on the basis of a response as to whether a subject visually recognizes a displayed stimulus for kinetic visual field examination. The stimulus is displayed a series of times on an inner surface of a visual field dome. An operation is performed in which the subject is made aware of an operating sound of the perimeter while no stimulus is actually displayed. The operation is performed at a predetermined frequency during the display times of the stimulus, and a duration of the operation is determined in accordance with a response time by the subject to the displayed stimulus. The reliability of the kinetic visual field examination is evaluated on the basis of the response of the subject in the performed operation.
