Patent JP-H0494181-A (JP)
Title: Laser oscillator
Inventor: HAMAGUCHI MASAHIRO
IPC: H01S3/038
Filed: 1990-08-10
Abstract: PURPOSE:To make it possible to obtain the optimum mode during each processing time by providing an induction means formed with a dielectric capable of moving freely between a discharge tube and a discharge electrode and changing the distribution of the intensity of discharge generated in said discharge tube. CONSTITUTION:When high frequency AC voltage from a high frequency power source is applied between discharge electrodes 11a and 11b, a laser medium filled in a discharge tube 10 is excited, thereby generating laser oscillation between a total reflected mirror 14 and a partial reflected mirror 15, a part of which is output as laser light by way of the partial reflected mirror 15. When a dielectric 12 is between the discharge electrode 11 and the discharge tube 10, it is possible to equalize application voltage to unit discharge length added the discharge electrode even in the central part of the electrode to an electrode section so that uniform discharge may be available, thereby obtaining single mode as a result. When the dielectric 12 is not between the discharge electrode 11 and the discharge tube 10, the discharge will be concentrated to the end of the electrode, which results in lower dimensional mode available.

Title: Motor drive controller
Inventor: NISHIBE TAIJI
IPC: H02P7/06
Filed: 1993-08-25
Abstract: PURPOSE:To control a motor so that the motor continues to be driven when a motor drive voltage fluctuates and no excessive current flows when the motor is overloaded. CONSTITUTION:A voltage fluctuation detection circuit 26 is provided for outputting a low-level signal (prohibition signal) to a control circuit 20 by the amount of time corresponding to a fluctuation width when a motor drive voltage increases to a specific width or more by monitoring the fluctuation of the motor drive voltage. Therefore, when the motor drive voltage increases on normal operation when a motor 12 is not overloaded, the voltage fluctuation detection circuit 26 outputs a prohibition signal to the control circuit 20 by the amount of time corresponding to the fluctuation width, thus driving the motor 12 while the prohibition signal is input even if the output of a comparator 22 is high in the control circuit 20. On the other hand, when an overload occurs in the case of the increase in motor drive voltage less than a specific width, the control circuit 20 controls the motor 12 so that no overcurrent flows based on the output of the comparator 22.

Title: Internal combustion engine with exhaust emission controlling catalyst
Inventor: TSUTSUMI YASUHITO
IPC: F01N3/24
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To uniformize engine output without correcting and controlling the ignition timing when an exhaust emission control device functions, by controlling a cylinder to the rich air-fuel ratio and the other cylinder to the lean air-fuel ratio when an exhaust emission controlling catalyst is not poisoned, and increasing or decreasing the amount of air to be introduced to respective cylinders according to air-fuel ratios of respective cylinders. SOLUTION: When an individual cylinder air-fuel ratio control means 30 is operated, the amount of air to be introduced to respective cylinders is increased or decreased by an individual cylinder air amount control means 50 according to the air-fuel ratio of a cylinder and the other cylinder. When the amount of fuel to be injected to respective cylinders is increased or decreased according to the increased or decreased air amount simultaneously with the increase or the decrease, output of cylinders 1A, 1D controlled to the rich air-fuel ratio is decreased, and output of cylinders 1B, 1C controlled to the lean air-fuel ratio is increased. As a result, torque (output) of respective cylinders can be made constant without changing the air-fuel ratios of respective cylinders.  Therefore, the difference of output between respective cylinders is eliminated, and operating feeling can be improved.
