Abstract: The present invention relates to a multi-temperature control refrigerator, in which an ice machine is installed and the cooling mode of the refrigerator is a mixed air-cooling and direct cooling mode. Particularly, the present invention relates to a refrigerator having ice-making function, in which the refrigeration cycle is a dual cycle and two different evaporators are included. Due to that the ice making room of the of the refrigerator of the present invention adopts a mixed air-cooling and direct cooling mode, and that impulse solenoid valves and dual temperature control device are introduced to the dual cycle system, the energy is optimally distributed and utilized, the fluctuation of temperature is small and the ice making efficiency of the ice making room and the quality of the ice cubes are much improved. And the whole refrigerator makes less noise, consumes fewer refrigerants and makes ice of good quality rapidly.

Abstract: A transmission mechanism suitable to be used in a washing machine for creating dual-direction driving comprises a drive power input end and two drive power output ends, in which one of drive power output ends is connected to an agitator shaft (10) to drive the agitator shaft rotating in a first direction; while the other of drive power output ends is connected with an inner basket shaft (11) to drive the inner basket shaft rotating in a second direction opposed to the first direction. A washing machine for creating dual-direction washing and a washing method for creating dual-direction washing in a washing machine are disclosed in the present invention. Furthermore, an agitator and an inner basket suitable to be used in the washing machine are disclosed in the present invention.

Abstract: The invention discloses a method and device for data-flow protection of an optical interface in data communication equipment. First, receiving an optical-signal from a source-neighboring device, then duplicating the received optical signal into two duplicated optical signals. One of them is sent to a protected device for processing. According to the protected device working status, either the optical signal having been processed by the protected device or the second duplicated optical signal is selected and sent to a destination-neighboring device. The device of the invention includes a first optical-signal duplicating unit and an optical-signal selecting unit. The first optical-signal duplicating unit is used for duplicating an optical signal, and the optical-signal selecting unit is used as a selector. The method and device proposed by the invention are independent to network topology and can protect data-flow reliably.
