Abstract: A liquid jet discharge device including an ejection section, a pressure generation section, and an impulse force impartation means. The ejection section is open at both end portions and internally houses a liquid such that a contact angle between the liquid and at least an inner face of the ejection section is less than 90°. The pressure generation section is in communication with one end portion of the ejection section, has a cross-sectional area larger than a cross-sectional area of the ejection section, has a length in a discharge direction of a liquid jet that is longer than a length in the discharge direction from the one end portion of the ejection section to a surface of the liquid, and houses the liquid at least at a bottom face side onto which the one end portion opens. The impulse force impartation means is configured to impart an impulse force to the pressure generation section.

Abstract: A liquid jet discharge device includes: a narrow tube having a tube shaped body that is open at both ends, and in which a discharge liquid being disposed therein, the discharge liquid contacting at least at an inner face of the narrow tube at a contact angle of less than 90 degrees; a container in which a transmission medium being disposed at a base side thereof where one end of the narrow tube is disposed, so as to enable pressure to be transmitted to the discharge liquid; an adjustment mechanism that causes a liquid surface of the discharge liquid inside the narrow tube and an interface of the transmission medium outside the narrow tube and inside the container to be staggered in position along an axial direction of the narrow tube; and a generation mechanism that generates a pressure wave in the transmission medium such that a liquid jet is discharged from the discharge liquid inside the narrow tube.

Abstract: A light guide body rotates integrally with an operation knob, has an incident surface that is a concavely curved surface recessed to a side opposite to a light source side, and rotates about a rotation shaft located so as to intersect the incident surface of the light guide body. The incident surface of the light guide body is a concavely curved surface recessed toward the side opposite to the light source (toward a Z1 direction) on a cross-section taken along an X-Z plane.

Abstract: An input device includes: a switch unit that has a fixed contact and a movable contact placed so as to be movable away from and toward the fixed contact; a rubber member provided so as to be elastically deformable, the rubber member pressing the movable contact; and a slide member placed so as to be movable so that the slide member can press the rubber member. The rubber member has a first load generating part, which presses the movable contact, and a plurality of load adjusting parts disposed so as to enclose the first load generating part. The slide member has a first pressing part, which presses the first load generating part, and a plurality of second pressing parts, which press the plurality of load adjusting parts.
