Abstract: A bending and extending device 1 comprises an elastic hollow guide unit 2 and a movable part 3 to be movably inserted into the guide unit 2. The movable part 3 is constituted, either partially or entirely, of a plurality of belt-like flexible parts 30a and 30b, which extend in the axial direction of the guide unit 2 and the flexible parts 30a and 30b are connected at distal ends.

Abstract: A weight of a movable portion in a shutter unit is reduced. For this purpose, an imaging device according to the present technology includes: an imaging element that receives light from a subject and performs photoelectric conversion; a control unit that controls a timing of a charge reset of the imaging element; and a shutter unit including a base part that is disposed on a front surface of the imaging element and includes an opening through which light passes, an opening and closing blade that shields a part of the opening from light depending on the timing of the charge reset, and a support part that supports the opening and closing blade. As a result, only one opening and closing blade is included, a width of the opening and closing blade in a traveling direction is smaller than a width of the opening in the traveling direction, and the weight of the movable portion in the shutter unit can be reduced.

Abstract: A vibration generation device capable of feeding back execution of image capturing to an image capturing person without affecting hand-shake correction control includes a vibration unit that generates vibration and a vibration control unit that performs vibration control on the vibration unit. In accordance with image capturing operation of an image capturing device, the vibration control unit causes the vibration unit to generate vibration at a second frequency band different from a first frequency band that the image capturing device has as a vibration range used for hand-shake correction control.

Abstract: [Problem] Image capturing is fed back to an image capturing person without affecting hand-shake correction control. [Solution] A vibration generation device capable of feeding back execution of image capturing to an image capturing person without affecting hand-shake correction control includes: a vibration unit configured to generate vibration; and a vibration control unit configured to perform vibration control on the vibration unit. In accordance with image capturing operation of an image capturing device, the vibration control unit causes the vibration unit to generate vibration at a second frequency band different from a first frequency band that the image capturing device has as a vibration range used for hand-shake correction control.

Abstract: A sterilization method is provided which acquires microbicidal activity equivalent to plasma-treated solution or more powerful than the same without the use of a plasma generation device. The sterilization method includes applying liquid containing peroxynitric acid (HOONO2) produced by chemical reaction to an object to be sterilized under acidic conditions of a pH value of 4.8 or lower. The liquid containing the peroxynitric acid is produced by mixing nitrous acid and peroxide together, for example, mixing nitrite and peroxide together.

Abstract: A method of producing a toner including the steps of: mixing resin fine particles, an organic solvent, and a resin R with a dispersion medium containing carbon dioxide, to prepare a dispersion of resin R-containing droplets; and removing the organic solvent by flowing carbon dioxide, wherein the resin fine particles contain one or more resins that have a partial structure A, B, and C, and are soluble in chloroform; the SP value of the partial structure A, the resin R, and the partial structure B satisfy particular relationships; a resin A constituted of the partial structure A and a resin B constituted of the partial structure B are soluble in the organic solvent; and a resin C constituted of the partial structure C is insoluble in the organic solvent.
