The invention discloses a draining-spinning control method for a multi-drum washing machine. The washing machine at least comprises a first washing drum and a second washing drum; before the first washing drum executes a draining procedure or a spin-drying procedure, whether the second washing drum is in execution of the draining procedure or the spin-drying procedure is judged; if the second washing drum is in execution of the draining procedure or the spin-drying procedure, the first washing drum continues to execute a washing procedure or a rinsing procedure, or the draining or spin-drying execution is suspended until spin-drying of the second washing drum is finished; if the second washing drum is not in execution of the draining procedure or the spin-drying procedure, the first washing drum starts the draining procedure and the spin-drying procedure. By means of the method, the first washing drum and the second washing drum cannot execute the draining-spinning procedures simultaneously and one washing drum continues to execute the washing procedure or the rinsing procedure during waiting, so that waiting time of the washing machine is used reasonably, and the clothing washing efficiency is increased. Meanwhile, the draining-spinning control method is simple, reliable, remarkable in effect and suitable for being popularized and used.

The invention provides a card device driving circuit which is used for providing driving voltage for a plurality of communication cards of a terminal device which comprises a main board. The card device driving circuit comprises a power supply connector, a time delay circuit, a first signal generation circuit and a second signal generation circuit. The power supply connector receives a control signal from the main board and transmits the control signal to the first signal generation circuit and the time delay circuit; the first signal generation circuit receives the control signal and outputs driving voltage to at least one communication card; the time delay circuit receives the control signal and outputs a time delay control signal to the second signal generation circuit after time delay; and the second signal generation circuit receives the time delay control signal and outputs the driving voltage to another at least one communication card. The card device driving circuit leads different communication cards not to need to be started simultaneously and reduces power of the main board of the terminal device during instant starting.

A washing machine comprises a first washing drum with a first heater and a second washing drum with a second heater. Before the first washing drum performs a heating procedure, it is necessary to determine whether the second washing drum is performing the heating procedure; if not, the first washing drum performs the heating procedure; if yes, it is necessary to determine whether the remaining heating time of the second washing drum is less than a set value, T min; if yes, the first washing drum pauses the heating procedure; when the second washing drum finishes performing the heating procedure, the first washing drum then performs the heating procedure; if not, remaining heating time of the first washing drum and that of the second washing drum are determined, whichever drum having the shorter remaining heating time performs the heating procedure first, while the other drum performs the heating procedure second.

The invention provides a color regulation method of a color sequence type liquid crystal display, which is applied to the color sequence type liquid crystal display comprising at least one white light source. The color regulation method comprises the following steps: firstly, converting an original image signal into a bit of target color point in a color degree map in a color space; then, calculating a modified image signal with a white datum according to the original image signal; next, using a matrix group for converting the modified image signal into a bit of main color point in the color degree map; and then, calculating a plurality of sub map field data according to the main color point and the target color point. The main color point falls on the target color point through the sub map field data.

The invention discloses an auxiliary power source bootstrapping circuit of a power source converting device, comprising an input filtering capacitor, a surge protection resistor, a surge protection switch, a bootstrapping charging resistor, a bootstrapping energy storage capacitor and an auxiliary power source. One end of the input filtering capacitor is connected with a high-voltage input positive end while the other end of the input filtering capacitor is connected with a common end of the surge protection switch; a normally-opened point of the surge protection switch is connected with a high-voltage input negative end; the surge protection resistor is connected in parallel between the common point and the normally-opened point of the surge protection switch; one end of the bootstrapping charging resistor is connected with a normally-closed point of the surge protection switch; the other end of the bootstrapping charging resistor is connected with one end of the bootstrapping energystorage capacitor; the other end of the bootstrapping energy storage capacitor is connected with a high-voltage input negative end; and a control power supply end of the auxiliary power source is connected in parallel at the two ends of the bootstrapping energy storage capacitor. The auxiliary power source bootstrapping circuit of the power source converting device has the advantages of reducing the power consumption and the occupation space and improving the reliability.
