摘要:
An automatic exposure control system permitting for a photographic camera to make an exposure in either of the shutter preselection automatic exposure range and the diaphragm preselection automatic exposure range is established by combination of an adapter unit with the camera. This adapter unit has a housing attachable to and detachable from the camera body, and includes an exposure operation and control circuit capable, upon preselection of an exposure time, of deriving an exposure value representing an effective exposure aperture, and, upon preselection of diaphragm value, of deriving an exposure value representing an exposure time. Responsive to the output of the adapter unit, the control device in the camera body controls operation of the shutter and diaphragm mechanisms thereof selectively in accordance with the exposure value derived from said exposure operation and control circuit. The provision for permitting the camera to make an exposure in an automatic flash exposure range is also made at the exposure operation and control circuit of the adapter unit in a manner to determine the period of energization of a flash unit associated with the camera.

An arteriosclerosis diagnostic device according to various embodiments is a simple device, resistant to an external factor, such as an error resulting from a skin surface, and capable of measuring the degree of hardness of an artery. The arteriosclerosis diagnostic device detects a heart sound and a pulse wave at least one location of a living body, the pulse wave propagating through an artery in relation to the heart sound, converts detected signals thereof into respective frequency signals, specifies the peak frequency of each of the frequency signals, and determines the degree of arteriosclerosis on the basis of the difference between the peak frequency of the heart sound and the peak frequency of the pulse wave. Accordingly, the degree of arteriosclerosis can be determined by comparison between the frequency signals.
