The invention relates to a method for preparing activated carbon with the high specific surface area through rapid activation under fluidization. The method is characterized by comprising steps as follows: 1) a biomass raw material with the particle size ranging from 0.3 mm to 0.9 mm is selected, soaked in a chemical reagent for 3-6 h and dried in a constant-temperature drying box at the temperature of 100-150 DEG C after soaking; 2) after drying, the dried material is stirred or crushed to form particulate materials; 3) a fluidized bed or a spouted bed is used as an activation reactor, the activation reactor is heated to 700-800 DEG C, fluidizing gas is introduced, quartz sand and the particulate materials obtained in the step 2) are placed, activation is performed for 1-10 min, a mixture is discharged immediately after activation and washed to be neutral with water, and the activated carbon with the specific surface area being 1267-1359 m<2> / g is obtained. According to the method, a chemical activation method is combined with the fluidized bed technology, rapid activation preparation of the activated carbon can be realized, the activation time is short, the prepared activated carbon has the relatively high specific surface area, the energy consumption is effectively reduced, and the production cost is reduced.

A station-side communication device connected to subscriber-side communication devices via an optical combining device; sending, to the subscriber-side communication devices, a distance measurement request signal; computing transmission delay times of optical signals from the individual subscriber-side communication devices by receiving distance measurement signals, and including: a threshold control part identifying the level of distance measurement signals; a signal detection part detecting breaks in the distance measurement signals from the threshold control part; a transmission granting part determining the timing at which transmission of optical signals is granted, and a reset timing generation part that, there is notification of detection of a break in the distance measurement signal from the signal detection part while it is being notified that distance measurement is carried out to and from the subscriber-side communication devices from the transmission granting part, sends a reset signal indicating that the voltage level is reset to the threshold control part.

A method to limit overheating of a brake equipped with an electromechanically actuable parking brake including the steps of: driving a threaded spindle by an electric motor until a power drain (Imax), corresponding to a brake application force (F), is reached; detection of a travel distance (x0) of the piston corresponding to the brake application force (F) of the brake caliper in a locked state; determination of a second travel distance (x1) by adding a further travel distance value (x11), which corresponds to the desired clearance value, to form (x0); driving of the electric motor until the second travel distance (x1) has been covered by the brake piston; and comparing the vehicle speed with a predefined first speed value, at the upward transgression of which the electric motor is driven once more in the release direction until a further, previously defined travel distance (x12) has been covered.

When a content is playbacked via a network, if a transmission-sided terminal of the content is under stopping condition, then a lengthy time is required until the content is playbacked. When an activation time of a recorder is measured and contents are recorded on this recorder, a content corresponding to the activation time is copied to another recorder so as to be shared by the own recorder and another recorder. In the case that the content is playbacked via the network, the content held in the own recorder is firstly playbacked, and when the recorder holding the content is activated, so that the content can be transmitted, the own recorder directly receives the content from the recorder holding the content to playback the received content.
