Abstract: A rotating electrical machine includes a rotor and a magnet unit. The rotating electrical machine also includes a cylindrical stator and a housing. The stator is equipped with a stator winding made up of a plurality of phase windings. The stator is arranged coaxially with the rotor and faces the rotor. The housing has the rotor and the stator disposed therein. The rotor includes a cylindrical magnet retainer to which the magnet unit is secured and an intermediate portion which connects between a rotating shaft of the rotor and the magnet retainer and extends in a radial direction of the rotating shaft. A first region located radially inside an inner peripheral surface of a magnetic circuit component made up of the stator and the rotor is greater in volume than a second region between the inner peripheral surface of the magnetic circuit component and the housing in the radial direction.

Abstract: A sheet detection device includes, as detection pieces, a first detection piece integrally provided on a rotary shaft and a second detection piece attached to the first detection piece via a biasing member. The second detection piece is capable of rotation in conjunction with the first detection piece under a biasing force of the biasing member. When the second detection piece is brought into contact with a ceiling at an upper part of the rotary shaft, the second detection piece stops further rotation while the first detection piece is capable of rotation together with the rotary shaft against the biasing force.

Abstract: An image forming apparatus includes a paper discharging tray and a paper detection part disposed at an upstream end of the paper discharging tray in a paper discharge direction. The paper detection part includes a base end member provided rotatably around a first axis extending in a direction perpendicular to a paper discharge direction and a tip member pivoted to the base end member to rotate around a second axis parallel to the first axis, and extending downwardly to incline toward an upstream side of the paper discharge direction in a state where the base end member is not subjected to pressure from the paper being discharged. The base end member is disposed to face a discharge opening when being at the reference position, and the image forming apparatus stops discharging paper from the discharge opening when the base end member rotates by a predetermined threshold or more with respect to the reference position.

Abstract: This information processing system includes: a controller including an operation element, a restriction member, a resistance section using a magnetorheological fluid whose viscosity changes with an applied-magnetic-field intensity and which serves as a resistance corresponding to the viscosity when the position of the operation element is displaced, and a magnetic field generation section to provide the magnetic field; and a circuit capable of controlling the magnetic field generation section. In a first state, a movable area of a position of the operation element is restricted to a basic movable area. In a second state, the magnetic field generation section is controlled so that the viscosity becomes a first viscosity, when the operation element is in a first area, and so that the viscosity becomes a second viscosity when the operation element is in a second area.

Abstract: An example of a controller includes a housing including an opening, and an operation member, a part of which is exposed through the opening. The operation member includes a key top exposed through the opening and operated by a user, a shaft portion extending downward from the key top, and a protruding portion protruding from the shaft portion. Further, in the housing, a pedestal with which the protruding portion of the operation member comes into contact when the operation member is tilted is provided. The tilt of the operation member is limited by the protruding portion coming into contact with the pedestal.

Abstract: An example input apparatus includes an elastic member, a base portion and a strain gauge. The elastic member includes a first end portion and a second end portion, and at least a part of the elastic member is elastically deformable. The base portion holds the opposite end portions of the elastic member so that a ring is formed by the base portion and the elastic member. The strain gauge is provided on the base portion and detects a strain generated on the base portion due to deformation of the elastic member in response to an input from the user. Note that instead of the configuration where a ring is formed by the base portion and the elastic member, the input apparatus may be configured so that two elastic members are held by the base portion.
