摘要:
In a four wheel simultaneous control mode when a regeneration cooperative braking is implemented, a pair of electromagnetic control valves 17A, 17B and one of normally closed electromagnetic valves 19FL, 19FR corresponding to regeneration side left and right wheel brakes 5FL, 5FR and normally closed electromagnetic valves 19RL, 19RR corresponding to non-regeneration side left and right wheel brakes 5RL, 5RR are caused to operate to open and close, while the other of the normally closed electromagnetic valves 19FL, 19FR corresponding to the regeneration side left and right wheel brakes 5FL, 5FR and the normally closed electromagnetic valves 19RL, 19RR corresponding to the non-regeneration side left and right wheel brakes 5RL, 5RR are put in inoperative states in which the valves concerned are kept closed, and all normally open electromagnetic valves 18FL, 18RR, 18FR, 18RL are put in inoperative states in which the valves concerned are kept opened.

There is provided a vehicle system, including an electromobile having a fuel cell power generator mounted therein, and a predetermined mobile unit jointable to the electromobile, such that cogeneration within the mobile unit can be realized even during the travel of the electromobile. Via a joint section 30, a vehicle 10 including a fuel cell 13 as a source of motive power is jointed to a mobile unit 20 capable of travelling and at least including a storage battery 23 and a water tank 25. The water produced in the fuel cell 13 is recovered by a water recovery section 21 via the joint section 30. The heat produced in the fuel cell 13 is recovered by a heat recovery section 22 via the joint section 30. The recovered water is warmed up with the recovered heat, and thereafter stored in the water tank 25. The hot water stored in the water tank 25 is utilized as hot water to be used for controlling the temperature of the mobile unit 20 or supplied as hot water. Any excess electric power generated by the fuel cell 13 is stored in the storage battery 23, and supplied onto electric wiring within the mobile unit 20.

A power driven circular saw includes a base able to slidingly contact a workpiece and a saw unit positioned above the base and supported by the base. The saw unit includes a motor case accommodating an electric motor, a handle extending from the motor case and able to be grasped by an operator, a circular saw blade rotatably driven by the electric motor and positioned to partly extend downward below the lower surface of the base, and a blade case for substantially covering the upper half of the saw blade. A power indication lamp is disposed on one side of the handle and is illuminated when power is supplied to the circular saw.

A drying apparatus for drying a moist material includes a container having an opening for receiving the material therein. A top cover is provided for closing the opening of the container. A heater and fan are provided on the bottom of the top cover so as to confront to the opening of the container when the top cover is closed. The heater and fan produce and blow a heated air stream toward the material to vaporize the moisture therein. A rotary drive unit is provided under the container to rotates the container for mixing the material. By the mixing operation, the material is stirred such that the inside portion the of material is moved up and is exposed to the heated air stream. The vapor released from the heated material is vent ed to the outside of the apparatus through a ventilation unit.
摘要:
A traction control method for a vehicle according to the present invention for generating braking forces in the brake devices for driving wheels when excessive slipping has occurred in the drive wheels involves an independent control mode for independently controlling respective braking forces of the plurality of drive-wheel brake devices and a collective control mode for collectively controlling the braking forces. These two control modes are interchangeable with each other. This enables traction control which can insure both reliable driving force and high stability.

A method for traction control of a vehicle, includes detecting a slipping tendency of a drive wheel in a driven state, and controlling the braking force of a drive wheel brake device in an increasing and decreasing manner in accordance with the degree of the detected slipping tendency, wherein a rapid increase mode of rapidly increasing the braking force of the drive wheel brake device and a slow increase mode of slowly increasing the braking force can be switched from one to the other, so that at an initial stage in increasing the braking force of the drive wheel brake device on the basis of the decision that the drive wheel is in an excessive slipping tendency, the braking force is increased in the rapid increase mode.
摘要:
An atomizer for atomizing liquid, having a disc clamped between two plate members, the disc being provided with a plurality of radial slits which, in combination with the flat surfaces of peripheral regions of the plate members, constitute liquid atomizing nozzle ports having a tetragonal cross-section. This arrangement permits an easy formation of a plurality of nozzle ports and remarkably suppresses the tendency of clogging of the nozzle ports by foreign matter. In addition, it is possible to form precisely fine nozzle ports of a diameter which could never be attained by the conventional process. The tetragonal cross-section of the nozzle ports provide peculiar jetting characteristics for attaining good atomization of the liquid.
