An anti-piracy storage media comprises a first storage space and a second storage space. The first storage space is of read-only attribute, and stores an anti-piracy software installation program, and the second storage space is used for storing a hardware identification code of an electronic device. When software is installed, the anti-piracy software installation program runs automatically, accesses the second storage space and reads the hardware identification code of the electronic device which operates the storage device, when the second storage space is accessed and has a hardware identification code which is the same as the read hardware identification code of the electronic device, or the second storage space has a write-once region which is not written and the hardware identification code is written in the region, the anti-piracy software installation program of the storage media can continue running and install the corresponding software in the electronic device. The invention further provides an anti-piracy method. By the anti-piracy storage media and the anti-piracy method, piracy can be prevented and the number of the electronic devices installed with the software canbe limited.

The invention relates to a burglar-proof safety hinge. The burglar-proof safety hinge comprises a hinge formed by two flat plates, and further comprises a built-in block corresponding to the flat plates. The flat plates are provided with an inserting block inserted in the built-in block. The inserting block is provided with a lock hole. The built-in block is provided with a slider. The slider is provided with a lock pin. The built-in block is provided with a stop dog passing through the slider. The stop dog is provided with a limiting chute. The flat plates are provided with a stopping block installed in the limiting chute. The slider is connected with the built-in block through a tension spring. The built-in block is provided with a second spline hole and an inserting hole. The flat plates are provided with an avoidance hole corresponding to the inserting hole. The burglar-proof safety hinge further comprises a spline shaft. A hinge installing method comprises the following steps: through combined action of a position change of the stop dog and a tension of the tension spring, controlling sliding of the lock pin towards the lock hole, and realizing cooperation and separation of the lock pin and the lock hole, thereby completing locking or unlocking between the flat plates and the built-in block.

The invention discloses a protective semiconductor device, which relates to a semiconductor device and solves the technical problems that the response speed, robustness and reliability of the protective semiconductor device are not fast enough under high voltage or high power, and the main points of the technical scheme It includes an N-type substrate region, a P-type anode region is arranged at the bottom of the N-type substrate region, a P-type base region is arranged on the top of the N-type substrate region, and a horizontally variable doping region is arranged in the P-type base region. Complex N-VLD region. Multiple electron-hole-electron-hole cycles can be formed between the N-VLD region and the P-type anode region, thereby forming a strong current between the anode and the cathode, and the dynamic current sharing effect of the N-VLD region Keep the working status of each cell highly consistent. Therefore, when there is a surge current in the external circuit, a very large current channel can be formed between the anode and the cathode by actively controlling the trigger electrode, which improves the ability of the device to pass the surge current and realizes the active protection of the circuit system.

The invention relates to an anti-disassembly hinge. The anti-disassembly hinge comprises a hinge, internal blocks and sleeves, wherein the hinge is formed by hinging of two plates, and the internal blocks correspond to the plates. An insertion portion provided with a lock hole is arranged on each plate, and a slider with a lock pin is arranged on each internal block. Stop blocks, penetrating the plates to be inserted into the internal blocks and penetrate the sliders, are arranged on the internal blocks. Limiting sliding grooves are formed in the stop blocks. Retaining blocks located in the limiting sliding grooves are arranged on the plates, and are connected with the internal blocks through springs. A first connection rod and a second connection rod are arranged on each internal block, and one end of the first connection rod is hinged with one end of the second connection rod. The first connection rods are hinged with the sliders, and the second connection rods are connected with rotating shafts. Hexagonal splines are arranged at the ends of the rotating shafts. The internal blocks are provided with insertion holes matched with the hexagonal splines. The sleeves are matched withthe hexagonal splines, and clearance holes are formed in the plates. A hinge disassembly prevention method includes inserting the lock pins into the lock holes slidably through a triggering device andseparating the lock pins from the lock holes through a pulling device so as to achieve locking and unlocking between the plates and the internal blocks.

The invention discloses an automatic anti-running mine car for inclined lanes and an anti-running braking method thereof. The inclined lane automatic anti-running mine car includes a mine car body, which can run along the inclined lane guide rail through the wheels; an anti-running clutch mechanism is arranged between the mine car body and the inclined lane guide rail; the anti-running clutch mechanism includes a speed limit sensing device , anti-running and arresting device and car arrester; the speed limit sensing device can sense the wheel speed, and when the wheel speed reaches the preset limit speed, it can send a trigger signal to the driving mechanism of the anti-running and arresting device; The catching device includes a catching component, a driving mechanism and a braking winch. The driving mechanism and the braking winch are fixedly installed on the mine car body; The active protection of alley transport vehicles can eliminate the occurrence of sports car accidents from the root cause and improve the safety of inclined alley transport.

The present invention provides a service request processing method and device, wherein the method includes: sending a query request for querying the server domain name to the domain name server DNS; receiving a query response returned according to the query request, wherein the query response carries an identifier The first identifier of the gateway IDGW; send a service request to the IDGW according to the first identifier, wherein the service request is used for the IDGW to convert the first identifier into the second identifier of the server, and according to the The second identifier forwards the service request to the server; and receives a service response message returned by the server in response to the service request.
