Abstract: A visual sense examination device includes: a beam source that emits a visible beam and an invisible beam; a visible beam optical system that includes a first scanner scanning the visible beam; an invisible beam optical system that includes a second scanner scanning the invisible beam; a detector that detects the invisible beam reflected by a retina of a subject; a controller that performs a first control; a synthesizer that synthesizes the visible beam scanned by the first scanner and the invisible beam scanned by the second scanner; and wherein scanning angles of the visible beam by the first scanner and the invisible beam by the second scanner are substantially the same, and projectable ranges of the visible beam scanned by the first scanner and the invisible light scanned by the second scanner are substantially the same on the retina of the subject.

Abstract: A terminal device (300) includes a projection target holding unit that holds projection information to be projected by an image projection device (200), a storage unit that stores position information indicating a position on the retina of a user (P) at which the projection information is to be projected, a position information acquisition unit that acquires the position information from the storage unit, an image data generation unit that generates image data (D) of an image (202G) that projects the projection information at the position indicated by the position information, and an image output processing unit that outputs the image data (D) to the image projection device (200). The image projection device (200) includes a light source unit that emits a light beam, an image input unit that inputs the image data (D) from the terminal device (300), a control unit that generates an image light beam based on the input image data (D) and controls emission of the image light beam from the light source unit, a scanning mirror that scans the image light beam, and a projection unit that projects the image light beam on the retina of the eyeball of the user (P) as the image (202G) represented by the image data (D).

Abstract: The present invention is a method for producing a cyclopentyl alkyl ether compound comprising reacting substituted or unsubstituted cyclopentene with an alcohol compound represented by a formula (2): R1OH in the presence of an acidic zeolite, the cyclopentyl alkyl ether compound being represented by a formula (1): R1—O—R2, wherein R1 represents a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, or a substituted or unsubstituted cycloalkyl group having 3 to 8 carbon atoms, and R2 represents a substituted or unsubstituted cyclopentyl group. The present invention provides a method that can produce a cyclopentyl alkyl ether with high reaction efficiency through a liquid-phase reaction even when the raw material feed rate (amount) is increased.
