A pressure control device with a fluid discharge prevention mechanism such that operation is reliable, size is small, weight is light, and cost is low. The pressure control device according to the present invention comprises a novel valve body housing a weight and a fluid discharge prevention valve together, a vessel body with a tank-communicating port, and a lid with an atmosphere-communicating port. The top circumferential surface of the valve body serves also as a vacuum pressure regulation valve in cooperation with the vessel body.

In order to keep the latched condition of a door lock proper even when the associated door is considerably deformed due to a vehicle collision or the like, the outside lever extending from the door lock proper is provided with a pointed portion which is directed toward an outer panel of the door. Upon deformation of the outer panel, the pointed portion is forced to stick into the deformed outer panel establishing a locked engagement therebetween and thus preventing the door lock proper from taking the unlatched condition.

A device for detecting the removal of a cylinder lock used on cars, trunks, etc. when an unjust force is applied to the cylinder lock. The device also detects the locked and unlocked conditions of the cylinder lock. Magnets and magnetic sensor switches are used. A magnetic shield plate shields the flow of magnetic flux between the magnet and the magnetic sensor switch. When an unjust force is applied to the cylinder lock to take off the cylinder lock, the magnetic shield plate will be removed from between the magnet and the magnetic sensor switch, causing the magnet to energize the magnetic sensor switch, thereby detecting the removal of the cylinder lock.In addition, when the cylinder lock is turned by a key, another magnet connected to a rotor of fixed on the cylinder lock approaches either of a pair of magnetic sensor switches, whereby the locked and unlocked conditions of the cylinder lock are detected.

A push-pull cable arrangement for selectively transmitting longitudinal motion to two separate destinations has an inner wire having a front end, a rear end and an intermediate node between the front and rear ends. The inner wire is enclosed with a first outer casing between the front end and the intermediate node, and with a second outer casing between the intermediate node and the rear end. A front end of the first casing facing the front end of the wire is stationary, and a rear end of the second casing facing the rear end of the inner wire is also stationary. There is further provided an intermediate unit having a first member to which a rear end of the first casing is fixed, and a second member to which a front end of the second casing is fixed. One of the first and second members is a stationary housing, and the other is a sliding member slidably contained in the housing. The housing and the sliding member receives the inner wire with the intermediate node slidably, and the sliding member is movable longitudinally of the wire in the housing. When the inner wire is pulled, the sliding member abuts against the housing and can not move, so that a pull motion is transmitted to the rear end of the wire. When the wire is pushed, the intermediate node causes the sliding member to move away from the housing, and this movement is transmitted to another destination.

An electronic lock system is provided with an audible entry monitor for confirmation of entry of an input code and a mischief preventive circuit for disabling the audible entry monitor for a given period of time in response to an excessive number of inaccurate code input attempts. The audio signal generator is associated with a pushbutton input unit having a plurality of push buttons. The audio signal generator is adapted to produce an audible signal whenever an input code is entered through the input unit. The audible signal generator is also associated with a comparator for comparing the input code and a permanent code. The comparator is adapted to allow the system to change a voluntary code and operates the audible signal generator to produce another audible signal for a predetermined period while the system is capable of accepting entry of the new voluntary code to be preset.

A stopper is provided on the inner wire of a Bowden cable type arrangement. The stopper allows the wire to be pulled in a first axial direction to operate one of two latch mechanisms and engages a shoulder defined in the second latch mechanism when driven in a second axial direction to produce a reaction which causes the tubular housing disposed about the wire between the second latch mechanism and a single handled actuating mechanism, to flex and pull a lever of the second latch mechanism for operating same, whereby a single lever can be used to selectively operate two different mechanisms.

A locking means for a trunk in an automobile is disclosed which can be unlocked by the rotation of a key inserted in a key cylinder of the trunk and which comprises a first switch provided at a proper location in the room of the automobile to open and close a D.C. circuit including an actuator means for unlocking the locking means. A second switch which is usually closed is provided in said D.C. circuit in such a way as to be opened by the rotation of said key inserted in the key cylinder of the trunk in a direction contrary to that for unlocking the locking means, thereby it becomes possible for a proprietor of the automobile who stands outside the automobile near the trunk to actuate the second switch so as to prevent the opening of the trunk by any other person against the will of the proprietor.
