A safety apparatus for a fuel tank in a vehicle includes a fuel tank for storing fuel, a gelling agent tank for storing a gelling agent which can gelatinize the fuel, a supply system for supplying the gelling agent in the gelling agent tank to the fuel tank, a tank-emergency detecting system for detecting an emergency in the fuel tank, and a control system for outputting a drive signal to drive the supply system. The control system outputs the drive signal under the condition that the tank-emergency detecting system outputs an emergency detection signal indicating an emergency in the fuel tank.

There is disclosed a fluid clutch device for controlling transmission of motive power of a vehicular engine to accessory equipment such as an oil pump for a power steering mechanism or an air compressor for an air conditioner. The clutch device includes first and second members arranged for relative rotation about a common axis. The first member is operated by the vehicular engine while the second member is constructed to operate the accessory equipment. The first and second members are accommodated in a hermetically sealed clutch casing which is filled with an electroviscous fluid. A source of high voltage potential is provided for applying a voltage to the electroviscous fluid, and various units for generating information regarding driving of the accessory equipment are also used. A clutch control unit is electrically connected to the source of high voltage potential and the information-generating units, and regulates the voltage applied to the electroviscous fluid based on the information generated from the information-generating units to vary a driving power for operating the accessory equipment.

An apparatus for regulating the pneumatic pressure of a tire according to the invention calculates the pressure difference between the specified pneumatic pressure entered therein through an input section and the actual pneumatic pressure of a tire measured by a pressure sensor and operates its air charging or discharging valve by specifying an extent of openness of the valve and a time for keeping the valve open as a function of the obtained pressure difference. Thereafter, it calculates the rate of change in the pneumatic pressure of the tire from the actual pneumatic pressure of the tire measured for the second time during the valve is kept open and, at the same time, the pressure difference between the specified pneumatic pressure value and the actual pneumatic pressure of the tire measured for the second time. Then, it calculates second time for keeping the valve open by dividing the pressure difference by the rate of change in the pneumatic pressure of the tire and operates its air charging or discharging valve by specifying for the second time the time for keeping the valve open while keeping the extent of openness of the valve same as that for the first time.

An electrical connector is disclosed which includes first and second connector housings for holding first and second terminals, respectively, a short-circuiting element accommodated in the first housing in electrical contact with two first terminals, a sliding element arranged on the second housing, and an urging element for urging the sliding element in a direction forward from the second housing. The first housing includes a pair of resiliently-deformable engaging arms each having an engaging protrusion. The second housing, releasably fitted to the first housing, includes a pair of first guide grooves for receiving the engaging arms. Each first guide groove has an engaging portion with which the engaging protrusion is held in engagement and a stepped wall portion formed adjacent to the front end of the second housing. The sliding element has a front tongue engageable with the short-circuiting element to disengage the same from the two first terminals. The engaging arms and the first guide grooves are constructed so that upon fitting of the connector housings, the engaging arms are resiliently deformed by the stepped wall portions to be brought into abutment with the sliding element to move the same towards the rear end of the second housing, whereas upon completion of the fitting, the engaging arms are restored to a released position where the engaging protrusions are held in engagement with the engaging portions of the first guide grooves, while permitting the sliding element to move in a direction forward from the second housing.
