摘要： A steam iron includes a sensor for detecting and measuring movement of the steam iron. The sensor is coupled to an actuator that regulates the flow of steam via a valve located between a steam chamber and steam outlets. The sensor can detect movement in three directions (X, Y, Z) and adjust steam generation based on speed of movement of the iron and tilt angle. A pre-heater is used to pre-heat water in a water chamber. The pre-heated water is provided to a steam chamber where it is later converted to steam.

摘要： A vertical contour correcting circuit that provides contour correction of a luminance signal at a horizontal color transition area of an image, thereby minimizing dot interference at the color transition area of a reproduced image. The vertical contour correcting circuit includes a vertical band-pass filter which outputs a level difference signal. The level difference signal is delayed to produce a first delay signal. The first delay signal is delayed to produce a second delay signal. An intermediate value signal is determined from the level difference signal, the first delay signal, and the second delay signal. The intermediate value signal and the first delay signal are added together so that their carrier color signal band components are canceled out.

摘要： A battery charging circuit and a battery charger that stabilizes operation when switching between charging modes. The battery charging circuit includes first and second transistors that form a current mirror circuit with an output transistor. The source terminal of the first transistor is connected to a first resistor, and the source terminal of the second transistor is connected to a second resistor. Each source terminal is connected to a switch circuit, which controls switching between a trickle charge mode and a fast charge mode. The supply of current to the first and second resistors from the discrete transistors reduces the difference in phase lag resulting from the CR time constant and stabilizes operation in the trickle charge and the fast charge modes.

摘要： A battery charging circuit that stabilizes operation when switching between charge modes includes first and second transistors. The first transistor has a source connected to a first switch circuit. The first switch circuit connects the second transistor to either one of first and second external terminals. A mode switch circuit generates a switch signal for switching from a trickle charge mode to a fast charge mode. The mode switching circuit provides the switching signal to a comparison circuit. After a predetermined time elapses, the mode switching circuit provides the switching signal to the switch circuit. The comparison circuit lowers a current restriction reference voltage, which determines a charging current value, and returns the current restriction reference voltage to its original value after switching modes.
