Inventor: BOLLIGER DANIEL
IPC: B23K20/00
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To obtain a method and means for enabling simple calibration of a wire bonder. SOLUTION: For parameter calibration of a wire bonder 3, a test chip 2 is used together with sensors 5 and 6. The sensors 5 and 6 are built beforehand in the test chip 2. Time passages of signals of the sensors 5 and 6 are detected at a distance from a connection point 4 to a bonding point thereabove, and then subjected to an electronic evaluation for the use of calibration of the wire bonder. The bonder itself can be calibrated with the use of these sensors 5 and 6. Furthermore, in normal operation of the wire bonder 3, the time at which application of ultrasonic waves to a capillary 11 is to be stopped is determined by a time passage of an impedance of an ultrasonic wave transducer which is supplying the capillary 11.

Filed: 1982-03-01
Abstract: PURPOSE:To prevent an air-fuel ratio from being overrich, by carrying out an increase  in quantity after engine starting and an air-fuel ratio compensation in time of idling,  while stopping the air-fuel ratio compensation at the idle in time of the starting increment, in case of a method to proeperly compensate for the basic injection quantity  in accordance with a state of engine rotation. CONSTITUTION:In a digital control circuit 54, the basic injection time is read out of a read-only memory on a basis of both the suction pipe pressure by a suction pipe  pressure sensor 23 and the engine speed by a crank angle sensor 44 whereby injection  30 is controlled. In this case, after engine starting, a fuel increment compensation is carried out in accordance with a coefficient of compensation read out according to the warm-up state by a water temperature sensor 46 and then the compensation is attenuated after the lapse of the specified time. Likewise, at the time of idling, the increase  and decrease compensation of fuel is carried out according to the coefficient of compensation being varied with the suction pipe pressure and the change of engine speed.  And, at this time, during the performance of increasing in quantity after the former's  starting, this method causes the latter so as not to carry out the air-fuel ratio compensation in time of idling.
