According to the present invention, there is provided a disk cartridge capable of being made compact although the disc cartridge has double structure, which cartridge is improved in light blocking effect and dustproof property, and is particularly suitable for use as a media disk. In this disk cartridge, a shutter is slidably mounted between an inner case and an outer case, and a joint surfaces of upper and lower halves of the inner case, and joint surfaces of upper and lower halves of the outer case are provided at positions at different heights. Light incidence preventing parts which consist of sets of a plurality of lines of ribbed projections are formed on an inner surface of the upper half and an inner surface of the lower half of the outer case.

A camera for imaging the periphery of a vehicle is provided, images imaged by the camera are stored, and a processed image obtained by processing a past image which has been imaged before reaching a current position is overlaid on a part of a current image, which is currently imaged, being a blind spot region by being hidden by a car body or the like so that a combination image is created. A contour line symbolizing the car body is combined with the combination image and the image is displayed.

A camera includes an outer cover; a lens barrel which is housed inside the outer cover in the state that a front face of the lens barrel is substantially in flush with a front face portion of the outer cover surrounding the front face of the lens barrel, whereas when the lens barrel is in a photographing-waiting state in which photographing is possible, the front face of the lens barrel is projected from said surrounding front face portion of the outer cover; a lens barrel state selector for selecting either one of setting the lens barrel in the housed state and keeping the lens barrel at a position in the photographing-waiting state, when a power supply of the camera is turned off; and a controller for controlling the camera such that the lens barrel is set in the housed state when the power supply of the camera is turned off in the state that the lens barrel state selector is selecting setting the lens barrel in the housed state, whereas the lens barrel is kept at the position in the photographing-waiting state when the power supply of the camera is turned off in the state that the selector is selecting keeping the lens barrel at the position in the photograph-waiting state.
摘要:
An immobilization carrier containing an electron acceptor compound is used in addition to glutaraldehyde and poly-L-lysine to immobilize an enzyme and an electron acceptor compound simultaneously to an electrode. For example, here are used diaphorase as the enzyme and 2-amino-3-carboxy-1,4-naphthoquinone (ACNQ) as the electron acceptor compound.
