Title: Dimer control circuit
Inventor: FUKUHARA SHIGEO
IPC: G09G3/08
Filed: 1987-12-09
Abstract: PURPOSE: To cut off an unnecessary short-circuit current at extinction or a modulated light time and reduce the power consumption by providing a 1st current bypass switch which is connected to a light emitting element in parallel, a 2nd current cutoff switch which is connected to a main current path in series, and a turn-on current supply part. CONSTITUTION: The turn-on current supply part is equipped with a high-frequency power source, diodes D1 and D2 for rectification, and a ballast transformer BT1. The turn-on power supply part supplies turn-on electric power to the light emitting element such as a discharge lamp LP through the 2nd switch S7. Further, the light emission time of the light emitting element is adjusted by turning on and off the 1st switch Q4 connected to the light emitting element in parallel with a pulse-width modulated(PWM) signal to turn off or misdulate the light emitting element. For example, when the 1st switch Q4 is turned on, the 2nd switch Q7 is turned off to cut off the short-circuit current flowing from the turn-on current supply part to the parallel circuit of the light emitting element and 1st switch Q4.  Consequently, a state wherein the short- circuit current flows although the light emitting element is in the modulated or turned-off state is suppressed.

Title: Robot with track error correcting function
Inventor: KATO TETSURO
IPC: G05B19/404
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To obtain a robot capable of correcting a track in reproducing operation by an operation program generated without considering the effect of gravitation. SOLUTION: Error corrections of respective axial position command values as outputs based upon a normal function as the CNC of a robot controller are made. Error correction quantities are found by interpolation cycles from the attitude of the robot and the relational expression of the axial moments and error quantities. The addition of the correction quantities is done after filtering. The transfer function of the filter is represented as 1/(K*(A/K*S+1)) (A: coefficient of dynamic friction, K: spring constant). Filtered commands are inputted for servocontrol to perform the servocontrol based upon the corrected position commands as inputs, thereby compensating track errors caused under the effect of the deflection of an arm, the strain of a rotary mechanism part, and play of a backlash, clearance, etc., due to the moment of gravitation and a force of inertia.

Abstract: PURPOSE:To delicately execute the input control of a motor-driven air blower by obtaining floor surface information by adding up an output of a sensor for detecting the dust, processing the output of the sensor for detecting the dust by the floor surface information and the dust quantity, and discriminating automatically the floor surface. CONSTITUTION:Passing of dust 12 is counted by a counting means 16 by an interruption function. When a unit time elapses, a count value of the counting means 16 is added up by an adding-up part 17. By executing a fuzzy inference from the count value of the counting means 16 and floor surface information obtained from an added-up value previously, an optimal input of a motor-driven air blower 2 is determined, and the count value of the counting means 16 is cleared. When a prescribed time elapses, the floor surface information is obtained from the contents of the adding-up part 17. As far as this is concerned, in the case of 'the carpet surface having many wasteful flocks', the counting means 16 tends to increase continuously, therefore, since the added-up count value also increases, the floor surface information is obtained from the count value of the adding-up part 17.

Title: Engine controller
Inventor: KURONISHI KIYOSHI
IPC: F02D41/22
Filed: 1994-11-19
Abstract: PURPOSE: To prevent torque-down performance from being degraded due to generation of mis-fire in a working cylinder, in some cylinders to which fuel supply has been stopped after receiving a prescribed torque-down request, by promoting combustion of the working cylinder when the number of the cylinders which require fuel supply stop is numerous. CONSTITUTION: An ECU 23 which controls a fuel injection value 18 receives a torque down signal TCS from a traction control unit when slippage occurs in a driving wheel to perform ignition timing delay angle correction and traction control due to fuel stop for some cylinders. While fuel supply to some cylinders is stopping, the air-fuel ratio of mixture supplied to the cylinders working without requiring fuel stop is changed to fuel leaner side than the one when fuel supply is not stopped because of no request of torque-down. The more the number of the cylinders which require fuel supply stop is, the lean degree of the air-fuel ratio of the working cylinder is decreased more to promote combustion and restrain mis-fire.
