Patent JP-H053606-A (JP)
Title: Controller for electric vehicle
Inventor: SASAKI TOSHIO
IPC: B60L9/18
Filed: 1991-06-24
Abstract: PURPOSE:To prevent idling and lowering of average acceleration by operating the difference between a circumferential acceleration detected from a driving wheel and an acceleration command value and the derivative of the difference and following up the acceleration command when the adhesive condition is good whereas restricting torque when the adhesive condition is bad. CONSTITUTION:Outputs from the motor speed detectors 4A-4D for driving wheels 3A-3D are converted through motor frequency operating means 5A-5D into rotational frequencies of motors for respective shafts which are then subjected to time differentiation 6A-6D and converted 7A-7D into circumferential accelerations of driving wheels. A maximum circumferential acceleration of driving wheel is then selected 8 and added to a command value fed from an acceleration command generating means 9 thus obtaining a difference (e). The difference (e) is then normarized 12X, differentiated 11 and further normarized 11Y to be subjected to fuzzy inference 13. The acceleration command is followed up when the adhesive condition is good and the difference (e) is low but when the difference (e) exceeds a predetermined value, a current control means 107 limits the input to an inverter 101 according to an integration results 14 thus restricting the torque of motors 2A-2D. According to the constitution, idling of each wheel is absorbed smoothly resulting in the improvement of comfortableness.

Filed: 1990-07-06
Abstract: PURPOSE:Always to perform marking made up of dots stable in quality by deciding whether an image signal is normal or defective in an image processor and restarting a laser beam oscillator with a marking controller until a dot satisfying a quality reference is marked. CONSTITUTION:The laser beam is projected from the laser beam oscillator 1 and condensed by a lens 6 through an optical fiber 4 to mark dots on a work 12. When the oscillation of the laser beam comes to an end, the marking controller 11 gives a command to a mirror driving device 3 to move a reflecting device 2 to a position (a), a picture of dots marked on the work 12 changes into parallel beams through a lens 6 and is reflected by the reflecting device 2 through an optical fiber 4. This picture of dots is converted by an image pickup device 9 to an electrical signal to decide whether it can be recognized normally in the image processor 10. When it cannot be recognized normally, another marking is indicated to the marking controller 11 and again the laser beam irradiates this dot and whether or not the dot which was irradiated again can be recognized normally is decided.

Abstract: PURPOSE:To attain a call from a subscriber with priority even in the congestion of a channel by providing the channel connecting an incoming channel of a line concentration circuit and an outgoing channel into the subscriber line concentration circuit by one to one. CONSTITUTION:A program stored in a central control unit 1 manages l sets of multiplexed channels of incoming channels 101-10m, 111-11n and outgoing multiplex channel 12 of a line concentration circuit 41 and checks the idle state of the outgoing channel when the call request takes place from subscribers 81-8m, 91-91n.
