Abstract: An electromagnetic valve device having two electromagnetic valves comprises a solenoid unit having a unit construction in the form of a hollow cylinder and having a pair of solenoids, and a valve unit having a pair of valve mechanisms and having a unit construction in the form of a substantially solid cylinder. The solenoid unit has a pair of coil bobbins, and a pair of caps accommodating said coil bobbins. The valve unit is fitted through a central through hole of the solenoid unit and thus mounted therein. The coil bobbins are fixed to a yoke interposed therebetween and thus joined together.

Abstract: A signal is received from a key having predetermined information. A discriminator determines whether the received signal from the receiver represents the predetermined information. An actuator performs a predetermined anti-theft operation in response to output signals from first and second detectors indicating that at least one predetermined one of the covering members is closed and locked. The operation of the actuator is disabled in response to an output signal from the discriminator indicating that the received signal represents the predetermined information. The key includes a magnetic element forming first predetermined information, and light emitting elements for emitting infrared ray carrying second predetermined information. The actuator performs the predetermined anti-theft operation in response to an output signal from a third detector indicating that the key has been removed from a predetermined key hole, in addition to the output signals from the first and second detectors.

Abstract: A signal is received from a key having predetermined information. A resulting output signal is discriminated as to whether it represents the predetermined information. A predetermined anti-theft operation is actuated in response to output signals from first and second detectors indicating that at least one predetermined one of the covering members is closed and locked. Operation of the actuator is disabled in response to an output signal indicating that the received signal represents the predetermined information. The key includes a magnetic element forming first predetermined information, and light emitting elements for emitting infrared ray carrying second predetermined information. The predetermined anti-theft operation is actuated in response to an output signal from a third detector indicating that the key has been removed from a predetermined key hole, in addition to the output signals from the first and second detectors.

Abstract: When a key is inserted into a key hole of a lock, magnetism creating means creates a magnetic flux corresponding to a predetermined magnetic code set in the key. Magnetism detecting means detects the magnetic flux and outputs a signal representing the detected magnetic flux. Decision means compares the signal value with a predetermined value, and outputs an agreement signal when the two values are the same. Driving means enables at least unlocking by key operation in response to the agreement signal. The magnetism detecting means outputs, as the above signal, a voltage corresponding to the magnitude of the detected magnetic flux or pulses having a frequency corresponding to same. At least one of material, dimensions, and thickness of the magnetic element determines the predetermined magnetic code. Further, an unlocking mechanism has a magnetic actuator which unlocks the lock by coupling the lock with unlocking means via a cam in response to the agreement signal.

Abstract: A folding key for vehicles, in which a key body is pivotally mounted in a dished cap so as to be capable of pivoting with respect to the cap. The key body has a pivot portion which is directly supported by a bearing bore formed in the cap, or which is clamped and supported between a first bearing portion provided in a bottom surface of a recess in the cap and a second bearing portion provided in a support member fitted in the recess in the cap. In the latter case, a resilient tongue is resiliently engaged with an inward end of the key body to retain the same. The cap has formed therein a cut-out with which the key body is engaged upon ultimate levelling of the key body. Preferably, the cut-out is formed in a portion of a peripheral edge of the cap, which is located at a rear of the peripheral edge with reference to an advance direction of the vehicle.
