Abstract: A cognitive impairment diagnostic apparatus includes: a display which displays a video for diagnosis of cognitive impairment on a display surface; an imaging unit which captures images of an eye of a subject; a detection unit which detects viewpoints of the subject on the display surface in time series based on the images captured by the imaging unit; a creation unit which creates a distribution map representing a distribution of the viewpoints detected by the detection unit; a storage unit which stores case characteristic data indicating a characteristic of a viewpoint distribution corresponding to a typical case in cognitive impairment; and a diagnostic unit which diagnoses cognitive impairment of the subject by determining whether the distribution map has the characteristic indicated by the case characteristic data.

Abstract: A SOI substrate fabricating method comprises the steps of: making a first etch-stop layer on a silicon substrate; polishing the surface of the first etch-stop layer; making a silicon buffer layer on the polished surface of the first etch-stop layer; making a silicon layer on the silicon buffer layer; making an insulating layer on the silicon layer; bonding one of major surfaces of a support substrate onto the insulating layer; and removing the silicon substrate, the first etch-stop layer and the silicon buffer layer and maintaining the insulating layer and the silicon layer on the one surface of the support substrate.

Abstract: An automatic temperature control system for a vehicle air conditioner including a cool air supply mechanism having an air flow control device, an air flow dividing device for dividing a cool air flow supplied from the cool air supply mechanism into a primary flow and a secondary flow, a heat source for heating the primary flow, and a mixing mechanism for mixing the primary flow as warmed past the heat source, and the secondary air which remains cool, with each other.
