Abstract:
A system and method for controlling speed of a vehicle include determining whether or not a stand-by braking torque is applied, determining an actual distance from a preceding vehicle in front of a vehicle, comparing the actual distance to a desired distance to determine whether the actual distance is greater than the desired distance, determining motor/engine torque to increase vehicle speed, and applying the motor/engine torque when the actual distance is greater than the desired distance. The system and method terminates application of stand-by braking torque upon receiving operator torque request.
Abstract:
A sheet supply system includes a sheet support table which is movable up and down and on which a stack of a plurality of sheets are supported, a sheet feed-out roller which feeds out the sheets on the sheet support table one by one from the uppermost one, and a table drive mechanism which moves the sheet support table up and down relative to the sheet feed-out roller. A level sensor detects the level of the uppermost sheet on the sheet support table, and a sheet feed-out level at which the uppermost sheet is kept during sheet supply operation of the system is set by use of an entry key. A controller actuates the table drive mechanism to move upward the sheet support table when the level of the uppermost sheet on the sheet support table as detected by the level sensor lowers by a predetermined value from the sheet feed-out level and stops the table drive mechanism when the level of the uppermost sheet on the sheet support table as detected by the level sensor reaches the sheet feed-out level.
Abstract:
In the speaker system, an acoustic pipe for conducting a sound wave is arranged in front of a speaker for reproducing a middle and low frequency sound. The acoustic pipe has a rectangular open end portion. A speaker for reproducing a high frequency sound is disposed within the acoustic pipe coaxially with and in front of the speaker for reproducing the middle and low frequency. With this construction, attenuation of middle and high frequency components of sound signals which are produced from the middle and low frequency sound reproducing speaker is suppressed. Moreover, it is possible to conduct the high and middle frequency components and a high frequency component, which is reproduced by the high frequency sound reproducing speaker, as naturally composed sound signals to the open end portion of the acoustic pipe. The speaker system thus exhibits excellent characteristics in sound image localization and articulation of sound, thereby providing a high tone quality to the TV. The TV may be miniaturized with the speaker system.
Abstract:
A vehicle turning behavior control apparatus for use with a multi-wheel automatic vehicle. The apparatus provides a difference between the braking forces applied to the nearside and offside wheels of the vehicle to produce a yaw moment in a direction to which the vehicle turns. The difference is determined based upon the vehicle steering angle and is modified based upon the vehicle lateral slip angle.
Abstract:
An electrostatic recording apparatus includes a magnet roll for conveying a developing agent along a predetermined developing agent convey path. A plurality of recording electrodes are arranged to oppose the magnet roll and along the developing agent convey path. An opposite electrode has a portion opposing the plurality of recording electrodes and is arranged with a predetermined gap from the plurality of recording electrodes. A voltage applying unit applies a recording voltage corresponding to supplied dot recording information to each of the plurality of recording electrodes to generate a transferring electric field for transferring the developing agent to the opposite electrode between the opposite electrode and the plurality of recording electrodes, thereby forming a dot recording image corresponding to the dot recording information on the opposite electrode. The voltage applying unit applies, between the plurality of recording electrodes and the opposite electrode, a recovering electric field for recovering a part of the developing agent transferred on the opposite electrode to the plurality of recording electrodes within one-dot recording period in which one dot of the dot recording information is recorded in the conveying direction of the developing agent.
Abstract:
An electrostatic recording apparatus includes a developing agent carrier member arranged along a predetermined developing agent convey path. A developing agent conveying section conveys a developing agent along a surface of the developing agent carrier member. A plurality of recording electrodes are arranged on the surface of the developing agent carrier member at a predetermined pitch. An opposite electrode is arranged to oppose the plurality of recording electrodes at a predetermined gap. A voltage applying section applies a voltage corresponding to recording information to each of the plurality of recording electrodes to selectively transfer the developing agent, which is conveyed along the surface of the developing agent carrier member, to the opposite electrode. The developing agent carrier member has a step at a portion on its surface shifted to an upstream side of a developing agent convey direction from a position closest to the opposite electrode. At least distal end portions of the plurality of recording electrodes project from this step toward the closest position to form projections. The projections are swingable in a direction of approaching or going away from the opposite electrode.
Abstract:
In order to improve the cornering of a vehicle under braking, control is based on the single angle and the rate at which the steering angle is changing. When the rate at which the steering angle is changing is high the braking force on the outboard side of the vehicle with respect to the direction in which it is turning, is reduced with respect to that on the inboard side while in the case that the steering angle is relatively large, the braking force on the inboard side is reduced with respect to that on the outboard side. As an alternative to brake force reduction, it is possible to increase the braking force on the side opposite to that wherein reduction would be implemented. Parameters which are used to weight the control are steering angle acceleration, which speed, and vehicle deceleration.
Abstract:
A vehicle turning behavior control system is mounted in an automotive vehicle having an anti-skid braking system. The control system has an electronic control unit to which a signal representative of a vehicle turning condition is input. The control unit is arranged to establish a difference between braking forces applied respectively to inside and outside wheels (with respect to a vehicle turning direction) in accordance with the turning condition representative signal so as to develop a yaw moment between the inside and outside wheels to promote a turning of the vehicle. The control unit also functions to control the braking force applied to the outside wheel in accordance with the braking force applied to the inside wheel by the anti-skid system in a manner such that the former braking force changes in a similar pattern to the latter braking force.
Abstract:
An apparatus for use with an automotive vehicle for controlling movement of a throttle valve in response to a change of the position of an accelerator pedal. A control circuit receives electrical signals indicative of accelerator-pedal and throttle-valve positions for calculating a value corresponding to a setting of the position of the throttle valve. The control circuit is connected to an actuator which moves the throttle valve to the calculated setting. The control circuit decreases the speed of closing movement of the throttle valve when the throttle valve position is at an angle less than a reference angle.
Abstract:
A speaker diaphragm of the present invention is prepared in a manner such that a boron layer is formed on one face of a dome-shaped metal foil by means of a physical vapor deposition method such as ion-plating, cathode sputtering, vacuum evaporation or the like, when necessary the metal foil is thinned by etching, and then, if necessary, another boron layer is formed on the other face of the metal foil. Alternatively, a metal layer is formed on the surface of the boron layer. The resultant speaker diaphragm is light in weight and high in modulus and also has appropriate internal mechanical resistance against vibration, thereby providing a speaker of high efficiency and satisfactory characteristics.
