Abstract: A vibration isolator having an inner passage of a communication tube that communicates the negative pressure chamber with the valve chamber. A pipe connection part and a supply/discharge pipe communicate the valve chamber with the supply/discharge port of a switching valve on the outside of the vibration isolator. The switching valve selectively communicates the supply/discharge port to either an intake manifold as the negative pressure supply source, or an atmosphere space. The negative pressure chamber communicates with the valve chamber through the communication tube on the inner peripheral side of the outer cylinder member. Thus, either of a negative pressure and an atmospheric pressure, which is same as a pressure in the valve chamber, can be supplied into the negative pressure chamber, by supplying either of the negative pressure and the atmospheric pressure into the valve chamber through the supply/discharge pipe and the pipe connection part.

Abstract: An earthquake-proof plinth includes a display floor plate that has an aperture configured to fit a middle section of an article seated on the plinth and that has a seat panel passing through the aperture and supported by a shaft extending vertically downward from the seat panel; a vibration sensor; a shaft stopper that stops the seat panel and shaft in a shock-absorbing elastic fashion when the article still on the seat panel falls and eventually has its middle section fitted in the aperture of the floor plate; and a retainer that normally retains the shaft in position to keep the seat panel flush with the display floor plate while it releases the shaft in response to a detection signal from the vibration sensor to let the seat panel and shaft drop.

Abstract: The present invention describes a device for locking a lever of a motor vehicle. The device permits an operator to quickly lock the lever in an engaged position and unlock the lever from the engaged position. The device may be used even when the manual dexterity of the operator is limited by protective equipment. The device includes a pin and spring. The pin passes through aligned holes in the flange and lever. Releasing the lever exerts a lateral force on the pin, thereby preventing the pin from lifting from the lever hole and locking the lever in the engaged position. The spring lifts the pin from the locked position when the lateral force is reduced. The device may be used on a brake or clutch lever of a motorcycle, thereby permitting the operator to have at least one free hand at a stop.

Abstract: A brake cylinder for pneumatically actuated vehicle brakes includes a parking brake spring-loaded brake section and a service brake section combined to form a structural unit in a housing. The housing is divided into two chambers by a piston. A cylinder spring of the spring-loaded brake section acts on another spring-loaded piston in the chamber, which can be blocked in relation to the first piston by a pneumatically actuated locking mechanism, and can be released from the first piston by the releasing action of the blocking mechanism. Following the release, the cylinder spring acts between the two pistons and moves the two pistons in relation to each other during a parking brake process. The pneumatically actuatable blocking mechanism acts only in an expansion direction of the spring.

Abstract: A hybrid brake apparatus for a vehicle includes a front hydraulically actuated brake circuit, a rear electrically actuated brake circuit, and a controller. The front hydraulically actuated brake circuit includes a master cylinder for providing pressurized fluid to the front brake circuit in response to an input applied to the master cylinder for applying a frictional front braking force. The rear electrically actuated brake circuit is controllable in response to the input for providing a frictional rear braking force. The rear brake circuit is controlled in accordance with a first predetermined relationship between the input and rear braking force during normal operation of the front brake circuit. If the controller detects a degradation of front braking force, the rear brake circuit is controlled in accordance with a second predetermined relationship between the input and the rear braking force, to thereby compensate for the degradation of front braking force.

Abstract: A status of one or more subsystems positioned on one or more trailers is communicated to a tractor electrically and mechanically connected to the trailer. The status may be automatically supplied by the subsystem or may be requested either by the operator of the tractor/trailer combination or automatically by another subsystem on either the tractor or the trailer. A spread spectrum data communications signal representing the status of a respective subsystem is superposed on the power bus. The status of the respective subsystem can then be determined from the spread spectrum data communications signal. Preferably, the status of the subsystem is indicated to an operator positioned on the tractor. A command for controlling a subsystem on a trailer can also be communicated from the tractor to the trailer over the power bus. A spread spectrum data communications signal representing the command is produced on the power bus, and the subsystem is controlled based on the spread spectrum data communications signal.

Abstract: A pressure balanced supply valve for use in a vehicular braking system. A housing defines a first chamber, a second chamber, a first fluid conduit for connection to a master cylinder, a second fluid conduit for connection to a hydraulic pump, and a third fluid conduit connected between the first and second fluid conduits. The second fluid conduit communicates with both the first chamber and the second chamber. A valve seat is defined in the third fluid conduit. A movable valve element is movable to a first position sealing against the valve seat to prevent fluid flow between the first and second conduits through the third conduit, and to a second position permitting fluid flow between the first and second conduit through the third conduit. The movable valve element is exposed to pressures in both the first and second chambers so as to be pressure balanced in operation.

Abstract: The power-off electromagnetic brake (2) attracts an armature that is pressed by a spring force to a rotating member by a magnetic attraction force that is generated by energizing an exciting coil, and brake force that is acting on the rotating member is released. A voltage control circuit (12) continuously energizes the exciting coil for a fixed length of time and generates a considerable magnetic attraction force in order to attract the armature to a yoke when a brake power source (14) is switched on during brake release. After the armature has been attracted to the yoke, the voltage control circuit (12) intermittently energizes the exciting coil at a set cycle and a set on/off duty ratio to hold the armature in an attracted state to the yoke, thereby reducing power consumption and heat generation.

Abstract: An energy absorbing tubular structure is formed of a molded or extruded polymer. The tube has a quadrangular cross-section with rounded corners. The walls of tube are corrugated with alternating convex and concave corrugations surfaces having a continuous constant radius, preferably with no flat spots. The corrugated walls have a constant thickness. The corrugations progressively deform during impact thereby providing a near perfect square wave force vs. deflection energy absorption curve at any predetermined nearly constant force level. The tube may be filled with polymer foam to vary the impact performance of the structure.
