A display device including a pixel section provided between a pair of substrates and including plural pixels; one or plural active components disposed in a frame region around the pixel section on one substrate of the pair of substrates; an insulating film provided in the frame region on the one substrate to cover the one or plural active components; and a sealing layer provided to seal the pixel section and cover an end edge portion of the insulating film in the frame region.

Display device and electronic apparatus

A display device includes: a pixel section provided between a pair of substrates and including plural pixels; one or plural active components disposed in a frame region around the pixel section on one substrate of the pair of substrates; an insulating film provided in the frame region on the one substrate to cover the one or plural active components; and a sealing layer provided to seal the pixel section and cover an end edge portion of the insulating film in the frame region.

A portable device having compact size while accommodating a mechanical key therein. The mechanical key has an opening and an internal space, which are in communication with each other. An engagement member, arranged in the internal space, is movable between a first position where it partially projects from the opening and a second position where it is accommodated in the internal space. A resilient member, which urges the engagement member from the second position toward the first position is arranged in the internal space, includes a fixing portion fixed to the mechanical key in the internal space. The portable device further includes a case having a key accommodation portion for removably accommodating the mechanical key. The key accommodation portion includes an engaged portion that is engaged with the engagement member when the mechanical key is accommodated in the key accommodation portion.

Portable device including mechanical key

A vehicle electronic portable key system including a master key and sub-key. A retainer is arranged in the vehicle to retain the sub-key. A control unit determines whether the master key or sub-key is located in a vehicle interior or exterior wireless communicatable area. When the key is located in one of the wireless communicatable areas, the control unit permits various operations of the vehicle in accordance with the communicable area in which the key is located. The control unit determines that the sub-key is in a lent state if the sub-key is removed from the retainer when the master key is located in the interior wireless communicatable area. In a state in which the sub-key is located in one of the wireless communicatable areas after removal from the retainer, the control unit limits the operations of the vehicle unless the sub-key is determined as being in the lent state.

Vehicle electronic key system

A cylinder lock includes a sleeve, and a key plug housed in the sleeve and having an output portion to output an interrupted motion of a clutch device by moving in an insertion and extraction direction by an insertion and extraction of a matching key. The key plug is formed by a pivoting spindle in which the output portion pivotally supports an input clutch element and an output clutch element of the clutch device in the output state by an insertion of the matching key.

Cylinder lock, clutch device and unlocking device comprising thereof

The portability of a mechanical key and a locking/unlocking key having the mechanical key is improved. The mechanical key is housed in a portable device in such a manner that a key plate is folded into two at a portion formed with an inner groove. Thus, the housing space for housing the mechanical key can be reduced and the portable device can be made smaller. Accordingly, the portability of the locking/unlocking key can be improved.

Mechanical key and locking/unlocking key

A cylinder lock includes a sleeve having a plurality of locking holes, a key plug housed in the sleeve and having an output portion to output an interrupted motion of a clutch device by moving in an insertion and extraction direction by an insertion and extraction of a matching key, and a plurality of key matching members movably supported to the key plug, arranged to be insertable and removable in the plurality of locking holes respectively, and withdrawn from the plurality of locking holes respectively by an insertion of the matching key into the key plug. A portion of key matching members among the plurality of key matching members has a hook protruding toward a key insertion direction, and the sleeve has an engaging portion engaging with the hook by a movement in a key insertion direction of the key plug in locking holes among the plurality of locking holes which correspond to the portion of key matching members in the state that the plurality of key matching members are inserted into the plurality of locking holes.

Cylinder lock and unlocking device comprising thereof

A portable device includes a main body, which has a mechanical key retainer, and a mechanical key, which is removably retained in the mechanical key retainer. An engagement projection extends from the mechanical key in a direction perpendicular to the direction in which the mechanical key is inserted into the mechanical key retainer. The engagement projection is formed from a resilient material. The mechanical key retainer includes an engagement recess for engaging the engagement projection when the mechanical key is retained in the mechanical key retainer. This structure reduces the size of the portable device and improves portability of the portable device.

Portable device and mechanical key

In a key cylinder a stopper plate is pressed into an imposing hole of a rotor, latching to a body and also intruding into engagement grooves of a second sleeve. When an authentic key is inserted into the rotor and rotated, a first sleeve is not rotated, and a second sleeve is rotated through the stopper plate. When a false key is inserted into the rotor the first sleeve rotates and the second sleeve is slid to the rear by slide bars, therefore the stopper plate separates from the engagement grooves, and the second sleeve is not rotated. The stopper plate has the function of being able to stop the movement of the rotor in the forward-rearward direction, and also the function of making the second sleeve rotatable by the rotation of the rotor, and so the construction of the key cylinder is simplified.
