    • In a motor driving device where a motor having a winding wire with small inductance value is driven by a digital control means comprised of control means including a current command value calculating means, a current control means and a PWM control means whose sampling periods are different from each other, when discrete signals sampled by the respective control means are zero-order-held, a motor current includes a lot of higher harmonic waves due to a quantization error, thereby increasing a motor noise.When an n-th-order hold means is provided between the respective control means with different sampling periods, the quantization error can be reduced remarkably, and thus the higher harmonic wave components included in the motor current are reduced, thereby greatly reducing the motor noise.

    • A control system of a lockup clutch of a torque converter of a vehicle automatic transmission. A basic manipulated variable is determined in response to the vehicle operating condition in accordance with a predetermined characteristic, and the lockup clutch engaging force is controlled in response to the variable. In the system, fuzzy reasoning is carried out using the detected vehicle operating parameters to correct the basic manipulated variable, and the engaging force is controlled in response to the corrected manipulated variable, when the control condition is met. The corrected manipulated variable is gradually decreased with respect to time when the vehicle driving state has shifted from a region in which the engaging force is controlled in response to the corrected manipulated variable to a region in which the lockup clutch is disengaged. In addition, the corrected manipulated variable is gradually increased when the vehicle driving state has shifted from a region in which the lockup clutch is disengaged to a region in which the engaging force is controlled in response to the corrected manipulated variable.

    • In the method for forming an optical waveguide according to this invention, an optical waveguide comprising a core of quartz as a main component, and a cladding layers surrounding the core is formed by deposition of glass fine particles by flame hydrolysis deposition and vitrifying the glass fine particle layers. This method includes a step of transiently increasing a feed amount of phosphorus to a flame burner in forming glass fine particle layers to be the cladding layers. Feeding phosphorus in this step for the first time after a glass fine particle layer is deposited without feeding phosphorus to the flame burner, whereby generation of foreign objects near the core dan be suppressed. The method for fabricating an optical waveguide according to this invention is for fabricating a core 132a or cladding layers 122 142 surrounding the core 132a by flame hydrolysis deposition and is characterized in that the glass fine particle layers are vitrified after the deposition of the phosphorus-content glass fine particle layer, whereby glass films 122a, 122b with a thickness of below 10 .mu.m are formed. This glass film forming step is repeated twice or more times to form the core or the glass layers to be the cladding layers surrounding the core. This invention can suppress inhomogeneous vitrified films and especially can make phosphorus concentrations in the cladding layers uniform. As a result, prapagation losses can be made small.
