Abstract: A planetary gear speed reduction device may include a magnetic sun gear; a plurality of magnetic planetary gears which each revolve around the magnetic sun gear while rotating; and a magnetic internal gear arranged surrounding the multiple magnetic planetary gears from an outer circumferential side. An outside diameter of the magnetic sun gear and an outside diameter of the magnetic planetary gears may be equal.

Abstract: An electronic locking system provided with an electronic lock may include a lock detecting part to detect locking condition of the lock; a power outage-detecting part to detect power outage; a charging part to supply electric power to the lock during power outage; a power-supplying part to supply power to the lock and charging part; and a switching part structured such that power is supplied to the lock from the power-supplying part in a primary state, and power is supplied to the electronic lock from said charging part in a secondary state. The switching part is in said primary state during normal operation where no power outage is detected. The switching part is structured such that, when power outage is detected, said switching part is switched from said primary state to said secondary state.

Abstract: An automatic open-close device for use with a fitting, the device may include a rack secured to the fitting; a pinion structured to mesh with the rack; a turn-driving mechanism structured to drive the pinion to turn; and a holding member structured to rotatably hold the pinion. The holding member may be movable between a meshing position in which the rack and the pinion are engaged and a disengaging position in which the rack and the pinion are disengaged. The rack and the pinion may be configured such that, when the holding member is in the meshing position and the driving mechanism drives the pinion to turn, the fitting opens and closes.

Abstract: A tubular motor may include a tubular case, a motor unit provided inside the case, and a first planetary gear unit placed inside the case at an output side in the motor shaft direction with respect to the motor unit. On the motor unit, a concave part may be formed in an output side end surface of an output side end plate section that supports a rotor, at an output side of the rotor. On the first planetary gear unit, a planetary carrier may include a supporting plate that overlaps with planetary gears at an counter-output side in order to support the planetary gears from the counter-output side. The first planetary gear unit may be immediately adjacent to the output side end plate section at an output side.

Abstract: An optical device may include a flat optical member; a reinforcement member which is bonded to a back side of the optical member and demonstrates stronger rigidity in a center area thereof than two side portions thereof when curved in a thickness direction in a first direction within an in-plane direction; and a driving device which switches a shape of the optical member together with the reinforcement member between a flat state and a curved state in which the optical member is curved in the first direction.
