Abstract: An imaging apparatus controls a focus position of an optical system by switching between a first mode where the focus position is moved alternately to first and second positions to determine an in-focus direction and a second mode where the focus position is moved in the in-focus direction. The apparatus includes an imaging unit that captures an image formed by the optical system, a detection unit that detects a vibration amount of the apparatus, a determination unit that determines, based on the vibration amount, a correction amount for reducing blurring, a correction unit that corrects the blurring by clipping a part of the image based on the correction amount, and a control unit that controls switching to the second mode if the in-focus direction is the same a predetermined number of times or more in succession. The predetermined number is changed based on the correction amount or the vibration amount.

Abstract: This invention provides a heating device ensuring sufficient adhesive force, even when it is removed from clothing and then reattached to different clothing. The heating device of the present invention comprises a bag unit 2 containing an exothermic composition A including an oxidizable metal that can generate heat by contact with air, one surface of the bag unit 2 being air-permeable; an adhesive layer 3 formed on the other surface of the bag unit 2; a first release sheet 4 provided on the adhesive layer 3 to cover the adhesive layer 3; and a second release sheet 5 provided on the first release sheet 4 to cover the first release sheet 4, wherein the first release sheet 4 has a release portion 41 and a residual portion 42; when the second release sheet 5 is removed from the first release sheet 4, the release portion 41 is removed together with the second release sheet 5 and the residual portion 42 remains on the adhesive layer 3.

Abstract: A thermotherapy device worn on a joint that includes a tubular holder composed of a stretchable material and a chemical warmer held in the holder. The holder has an accommodating portion in which the chemical warmer can be placed and removed therefrom, or to which the chemical warmer can be attached. The thermotherapy device can maintain temperatures suitable for thermotherapy for a long period, remains in place despite the motion of the joint, and can hold a heat-generating member in a suitable area. The thermotherapy device is thus effective for use on joints.
