摘要： The control apparatus for controlling a voltage transforming apparatus having a transformer, power switching elements disposed in a primary side, and synchronous-rectifying switching elements disposed in a secondary side includes a judging circuit making a judgment as to whether or not an output current of the voltage transforming apparatus is smaller than a specified current on the basis of a primary-side current of the transformer and an inhibition circuit inhibiting the synchronous-rectifying switching elements from performing their synchronous-rectifying control operation when the judging circuit judges that the output current is smaller than the specified current. The judging circuit makes the judgment on the basis of the primary-side current flowing through the primary coil of the transformer immediately before the power switching elements are turned off.

摘要： A power converter is preferably mounted in a vehicle. The converter has a power converting unit including an electrical switching element electrically switched on and off selectively in response to a duty ratio of PWM (pulse-width modulation) signal given to the switching element. The converter further has a controller including a drive unit that generates the PWM signal, in addition to a controlling unit and a limiting unit. The controlling unit controls the duty ratio of the PWM signal such that a voltage inputted to the power converter is converted to a voltage to be outputted depending on the duty ratio. The limiting unit limits at least one of a time change amount of the duty ratio of the PWM signal and a maximum duty ratio of the PWM signal.

摘要： A driving circuit has a p-channel transistor and an n-channel transistor. A power switching element is set at an on state each time the p-channel transistor sets a charging line at a conductive state in response to a leading edge of an output pulse to supply a positive charge to a gate of the element through the charging line. The element is set at an off state each time the n-channel transistor sets a discharging line at a conductive state in response to a trailing edge of the output pulse to discharge the supplied charge through the discharging line. A through current occasionally flows through the transistors set at the on state together. The driving circuit has resistors between the transistors to suppress the through current.

摘要： An impact resistant styrene resin is prepared by the continuous bulk polymerization of a styrene monomer in the presence of a second component having a 5 wt % styrene solution viscosity which may be polybutadiene, styrene-butadiene copolymerization rubber, or mixtures thereof. Preliminary polymerization is carried out in a reactor having a dynamic mixing structure and which is integrated between and connected to the material feed line and the initial-stage polymerization line.
