The invention provides a test method and a device for an audio communication system, the audio communication system includes a first communication terminal and a second communication terminal, wherein, the method includes: first step, a first video signal pre-produced is imported into the first communication terminal under the condition that the first communication terminal is communicated with the second communication terminal; second step, frequency and / or amplitude of a second video signal are / is imported by the second communication terminal; third step, the frequency and / or the amplitude between the first video signal and the second video signal are / is compared with each other, and frequency different and amplitude different of both are judged whether to be in the range of pre-established inaccuracy or not, the audio communication system is decided to normally work if the difference is in the range of the pre-established inaccuracy; else, the video communication system is decided to work abnormally. The device includes: a signal import module, a signal export detection module and a comparison module. The invention can eliminate the inaccuracy of a subjective test in a prior art depended on man-made subjective feeling.

Provided are a peeling member that can suppress the phenomenon of peeling sheet creasing, can have sufficient linear contact with a roller, can prevent deformation by jamming of paper, and can exhibitsuperior paper peeling performance, and a peeling device provided with this peeling member. The peeling member, which has a peeling sheet (10) for peeling paper from an electrophotographic device fuser roller (6), is formed from one metal plate and has a peeling part (2) constituting a tip part and a support part (3) that is thicker than the peeling part (2). The peeling part (2) is provided on one long side of the metal plate, a paper passing surface (2b) thereof is a flat surface continuous with the surface of the support part (3), and the side opposite from the paper passing surface is aninclined surface (2c) inclined with respect to the paper passing surface (2b) such that the thickness of the peeling part (2) increases from the very tip (2a) of the peeling part (2) toward a boundarypart (2d) with the support part (3). The inclined surface (2c) is the surface disposed on the fuser roller (6) side, and distance (D1) between the very tip (2a) and the roller and distance (D2 from the boundary part (2d) and the roller satisfy D1<=D2<=5*D1.

The present invention relates to an assembly-type non-adhesive floorboard that tightly contacts the floor and can be easily installed, dismantled, and maintained and a method for tightly installing a floorboard using same, the floorboard comprising: a base panel made of an elastic material; a surface material, which is made of a material that is harder than the base panel, and which is laminated on the upper surface of the base panel; and an anti-slip sheet laminated on the lower surface of the base panel, wherein a protrusion and a coupling groove, to which the protrusion is coupled, are formed on both sides of the base panel such that the floorboard can tightly contact the floor firmly while facilitating installation and dismantling thereof. The present invention is advantageous in that, when floorboards are assembled by coupling protrusions to the coupling grooves and are placed on the floor of a building, anti-slip panels are forced against the floor; the base panels are made of calcium carbonate boards, which are elastic, such that, even if the floor is not completely level but is curved, the base panels are deformed appropriately and the entire anti-slip panels make a completely tight contact with the floor without detaching upward from the floor; accordingly, the assembly-type floorboards can be effectively forced against and fixed to the floor without having to use an adhesive, thereby facilitating installation and dismantling thereof; and, during heating, heat is effectively transferred from the floor to upper surfaces, and no jolt occurs even when the floor is uneven.

The invention relates to a hierarchical virtual closed-loop control method and system for a turntable. The method comprises: writing a closed-loop function of each loop in the closed-loop system, wherein the closed-loop functions are hierarchically independent, and each loop comprises a position loop, a speed loop and a current loop; and determining a closed-loop mode and selecting a closed-loop function according to the corresponding closed-loop mode for closing loops, wherein the closed-loop mode comprises a position loop closed-loop mode, a speed loop closed-loop mode and a current loop closed-loop mode. The hierarchical virtual closed-loop control method and system for the turntable solve the problem of complex multi-loop function nested debugging in the prior art.
