A sensor driving device includes a first substrate; a second substrate disposed on the first substrate; and an image sensor. The second substrate includes a body having first and second lateral surfaces; a first protrusion part protruding from the first lateral surface; and a second protrusion part protruding from the second lateral surface. The first protrusion part includes a first extension part, and a second extension part extending in a direction different from the first extension part. The second protrusion part includes a first extension part, and a second extension part extending in a direction different from the first extension part. The first extension parts are disposed parallel to an optical axis of the image sensor. The second extension part of the first protrusion part is closer to the second extension part of the second protrusion part than to the first extension part of the second protrusion part.

A molded coil includes a bobbin, a coil, and an exterior member. The coil is wound around the bobbin, and generates a magnetic force in reaction to power supply. The exterior member covers the coil and the bobbin therewith. Two seams, a first seam and a second seam are provided between the bobbin and the exterior member. A first seal member is disposed on an upstream side of the first seam and between a cover member and the exterior member. A second seal member is disposed on an upstream side of the second scam and between a flange portion of a stator core main body and the exterior member.

An enhanced safety coil that prevents crack formation and propagation to the coil windings from external sources and prevents exposure to fuel is provided. The enhanced safety coil may be used in a solenoid operated gas admission valve (SOGAV), and includes a plastic encapsulation body having at least one body de-stress feature, a coil wound on the plastic encapsulation body, a sleeve forming an outermost side protective wall configured to accommodate the plastic encapsulation body and coil therewithin, and potting provided between the plastic encapsulation body and the sleeve to seal the coil therein. The body de-stress feature is configured to reduce at least one of a formation or a propagation of a crack through the potting to the coil. The plastic encapsulation body forms retention latches configured to mate with a stator.

Provided is a secondary shutdown structure of a nuclear reactor, which uses sliding doors, and more particularly, to a secondary shutdown structure of a nuclear reactor, which uses sliding doors and is capable of shutting down a nuclear reactor reliably with a simple structure without using a boric acid solution.

An electromagnetic actuating device includes a sleeve, an armature situated radially inside the sleeve, and an electromagnetic coil situated radially outside the sleeve, the armature having a first armature end face on one end and a second armature end face on the opposite end. The sleeve has a channel on or in the sleeve wall, which extends in the longitudinal direction of the sleeve and forms a fluid connection between the armature end faces.

An electromagnetic actuating device (8) is for a variable valve drive, in particular electromagnetic switching valve lever systems. The electromagnetic actuating device comprises a base plate (3), a housing which is secured to the base plate (3) and a coil. The housing is designed as a bracket housing (12) and can form part of the magnetic circuit.

An optical member supporting device is described that includes, in an XYZ rectangular coordinate system, spherical bodies, a first holding portion and a second holding portion, an optical member held by the first holding portion or the second holding portion, first yokes protruding from the first holding portion facing the second holding portion, and second yokes protruding from the second holding portion facing the first holding portion and opposed to the first yokes in a predetermined direction in the X-Y direction. The first holding portion and second holding portion extend in an X-Y direction and are opposed in a Z direction with the spherical body interposed therebetween. The second holding portion includes a second magnet and the first yokes and the second yokes are opposed to the second magnet in the Z direction.

A controller for a linear solenoid valve is configured to: calculate an average value of an exciting current within a period including a natural number multiple of the dither cycle as an average current value; execute a feedback control on a control value of the pulse width modulation signal such that a target value of the exciting current and the average current value match; and calculate a dither correction amount by multiplying a ratio between the control value of the pulse width modulation signal obtained by the feedback control and the average current value by a dither current value that is a current value corresponding to the dither correction amount and calculating the dither correction amount such that an increase in the exciting current due to the dither correction amount is canceled out by a decrease in the exciting current due to the dither correction amount within one dither cycle.

A washing machine includes a washing tub rotatably disposed to accommodate laundry, a pulsator rotatably disposed in the washing tub, a drive shaft to rotate the pulsator, a dehydration shaft to be connected to the washing tub and through which the drive shaft passes, a solenoid to form a magnetic field when a current is applied, a fixing core to surround the solenoid, and a clutch to couple and uncouple the drive shaft and the dehydration shaft. The clutch includes an armature to be lifted by a magnetic force of the solenoid, and a clutch coupler to be elevated along the dehydration shaft, perform coupling between the drive shaft and the dehydration shaft in a first position, and perform uncoupling between the drive shaft and the dehydration shaft in a second position lifted from the first position.
