An offset correction method for a potential difference measuring apparatus (100) includes placing a pair of electrode portions (10) including a first electrode (11a) and a second electrode (12a) at a predetermined first position and measuring a first potential difference (V1), placing the pair of electrode portions (10) at a second position at which positions of the first electrode (11a) and the second electrode (12a) at the first position are reversed, and measuring a second potential difference (V2), and calculating an underwater electric potential (Vs1) in which at least an offset of a potential difference caused by a factor other than a test object (80) has been corrected, based on the first potential difference (V1) and the second potential difference (V2).

A current density measuring apparatus (100) includes an underwater electric field sensor (1) including a pair of electrode portions (10) and a potential difference (V) measuring unit configured to measure a potential difference (V) between the pair of electrode portions (10) without contacting a test object (80) placed in water, a conductivity meter (2) configured to measure a conductivity (σ) in the water, and a controller (3) configured or programmed to acquire a current density (J) of a current (70, 71) flowing from the test object (80) into the water using the potential difference (V) measured by the underwater electric field sensor (1) and the conductivity (σ) measured by the conductivity meter (2).

An analysis support system (1) is an analysis support system (1) for supporting an analysis task in an analysis apparatus (200), comprising: a voice device (10) configured to be worn by each analyst using the analysis apparatus (200) and to perform analysis support by voice; and a terminal device (100) provided corresponding to the analysis apparatus (200) and connected to the voice device (10) via wireless communication. The terminal device (100) includes: a storage unit configured to store support information for the analysis apparatus (200) and analyst information including a proficiency of the analyst in the analysis task; a communication unit configured to authenticate wireless communication with the voice device (10) of the analyst who is within a predetermined range of the analysis apparatus (200); and a terminal processing unit configured to identify the analyst authenticated by the communication unit and capable of wireless communication, and to output the support information for the analysis apparatus (200) corresponding to the proficiency of the identified analyst to the voice device (10).

An image display device (1) comprising: an image generation unit (10) that emits a light flux forming a predetermined image as a parallel light flux; and a light guide (20) that propagates the parallel light flux internally, the light guide (20) having a light flux introduction unit (23) into which the parallel light flux emitted from the image generation unit is introduced, a propagation unit that propagates the introduced parallel light flux while totally reflecting it internally, and a light extraction unit that extracts a part of the parallel light flux propagated through the propagation unit by a beam splitter (22), wherein the beam splitter is one in which reflective portions (222) that reflect the parallel light flux are formed in a two-dimensional arrangement.
