Abstract:
An active vibration insulator includes an electromagnetic actuator, a control-signals generator, a control-signals compensator, and a driver. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The control-signals generator generates control signals, which actively inhibit vibrations generated by a vibration generating source of a vehicle from transmitting to a specific part of the vehicle, based on cyclic pulsating signals output from the vibration generating source. The control-signals compensator compensates the cyclic control signals, which the control-signals generator generates, depending on output voltages of a battery. The driver is connected between the battery and the electromagnetic actuator, and makes the electric-current supplies variable based on the cyclic control signals, which the control-signals compensator has compensated, and the output voltages of the battery, thereby driving the electromagnetic actuator.
Abstract:
An active vibration insulator includes an electromagnetic actuator, a control-signals generating device, a driver, a calculator, and a judging device. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The control-signals generating device generates cyclic control signals based on cyclic pulsating signals output from a vibration generating source of a vehicle. The cyclic control signals actively inhibit vibrations generated by the vibration generating source from transmitting to a specific part of the vehicle. The driver drives the electromagnetic actuator by making the electric-current supplies variable based on the cyclic control signals. The calculator calculates an estimated transfer function composed of estimated values of a transfer function for a transfer system including the electromagnetic actuator and the driver. The judging device judges an inoperative malfunction of the electromagnetic actuator based the estimated transfer function.

Thus, it is possible to inhibit the vibration generating source from vibrating effectively and less expensively.
Abstract:
A damper main body of a dynamic damper comprises a long flat mounting plate portion, a rod-like central supporting metal member which is erected vertically in the center of a top face of the mounting plate portion, constituting a supporting member together with the mounting plate portion, cylindrical rubber bushings placed on the central supporting metal member in succession from its bottom side, a coil member, a magnet portion, a yoke and a cylindrical case mounted over the yoke. Grommets, which are cylindrical supporting portions made of rubber elastic bodies, are inserted into mounting holes in side plate portions of the mounting plate portion. The damper main body is fixed on a mating plate member through the compressed grommets such that it is floated over the mating plate member.
Abstract:
When a fuel reforming system for a fuel cell comprising an autothermal reformer 1 wherein a partial oxidation reaction and steam reforming reaction proceeds simultaneously, is stopped, firstly, a supply valve 6 is closed to stop supply of fuel and water for steam reforming, and a supply valve 7 is closed after a predetermined time has elapsed to stop supply of air. In this way, the partial oxidation reaction which is an exothermic reaction is continued temporarily and the catalyst layer temperature of the reformer 1 is raised, so the catalyst layer temperature can be maintained high until the system restarts, and the time required for restarting the system can be shortened.
Abstract:
Disclosed is a pneumatically operated fluid-filled active vibration-damping device including: a primary fluid chamber partially defined by an elastic body and filled with a non-compressible fluid; a movable member being elastically displaceable and partially defining the primary fluid chamber its one side; a working air chamber disposed on the other side of the movable member; and an air reservoir directly extending from the working air chamber and fluid-tightly closed at its protruding end portion. A fluid pressure variation in the primary fluid chamber is induced by an elastic deformation of the elastic body while being actively controlled by transmitting an air pressure variation applied to the working air chamber from an external area to the primary fluid chamber via the movable member. A vibration-damping apparatus using the vibration-damping device is also disclosed.
Abstract:
The color determination circuit 308 detects hue of the color image information, and the controller 205 decides a color component to be separated (separation color) in accordance with the detected hue. Output color by the printer 204 is set in correspondence with the separation color. The two-color-separating circuit 303 separates the color image information into image information on at least two color components in accordance with the decided separation colors. The separated image information on the each color is transmitted to the printer 204 via printer density correction circuits 304 and 305, and a buffer 306. Thereby it is possible to provide an image processing apparatus capable of setting and changing the separation color and the output color by automatic operation or by simple manual operation, thus the expression of the image forming can be improved.
Abstract:
Two A-shaped brackets for clamping three linearly located injectors onto a cylinder head of an engine. Each bracket has one top branch and two foot branches. Two top branches of the two brackets cooperatively press down a center injector among the three, and two pairs of foot branches of the two brackets press down two side injectors, respectively. Each injector has a flange that is pressed down by the two top branches of the two brackets or the two foot branches of the associated bracket Each bracket has an opening at its approximate center so that a screw shaft extending from the cylinder head can penetrate. Each bracket is secured on a cylinder head by tightening a nut over the screw shaft.
Abstract:
A wheel support device which is easy to assemble and compact in size. A pair of tapered roller bearings are mounted on the outer periphery of an axle. The pair of tapered roller bearings rotatably support an axle hub that rotates together with a wheel. A seal assembly is mounted between the outer and inner rings of one of the tapered roller bearings. The seal assembly prevents leakage of grease sealed in the axle hub and entry of muddy water from outside, and makes it unnecessary to provide a separate seal member, thus making it possible to assemble the wheel support device easily and to reduce its size.
