The application module is used for executing a main function of the portable electronic device. The active near area communication module is coupled to the application module and used for communicating with the near area communication devices outside the portable electronic device. The passive near area communication module is used for communicating with the near area communication devices outside the portable electronic device. The power supply unit is coupled to the application module and the active near-area communication module, and is used for providing power required by the application module and the active near-area communication module.

The invention discloses a repeatedly opened and closed anti-leakage valve with a cylindrical panel valve sealing structure. The anti-leakage valve comprises a valve body formed by combining a positioning connector, a locking cylinder and a lower connector, and a tubular mandrel a capable of moving in a reciprocating mode is arranged in the valve body and driven by an opening and closing tool to move in the reciprocating mode; a valve plate and a valve base which are matched are arranged at the position, close to the lower end, in the valve body, the valve plate is installed on a supporting base and arranged close to one side of the mandrel a, the supporting base is fixed to the inner wall of the valve body, and the valve base can move in a reciprocating mode in the axis direction of the valve body. When the anti-leakage valve is opened, the mandrel a moves downwards, the valve base is pushed to move downwards through a transmission mechanism, and when continuing to move downwards to make contact with the valve plate, the mandrel a pushes the valve plate to rotate in the side direction so that the anti-leakage valve can be opened; when the anti-leakage valve is closed, the mandrel a moves upwards, the valve plate is automatically reset under the action of a reset spring, and the mandrel a continues to move upwards and drives the valve base through the transmission mechanism to move upwards to press the valve plate in an abutting-against mode so that the anti-leakage valve is closed. The contact faces of the valve plate and the valve base are cylindrical surfaces.

The invention relates to a parking lot management device. The parking lot management device includes a platform selector configured to refer to information associated with a parking lot having a plurality of platforms and select one or more platforms from among the plurality of platforms in response to a leaving request for requesting movement of a vehicle parked in the parking lot from a parkingposition of the vehicle to the platform.

The invention discloses a bending die for producing an electric box. The bending die comprises an upper bending module and a lower bending module. A sliding block pedestal is arranged at the bottom of an upper die base. Bending sliding blocks are correspondingly arranged on the left side and the right side of the sliding block base. The bending sliding blocks are connected with the upper die base through locating rods. A plurality of sliding chutes are formed in the outer wall on each of the left side and the right side of the sliding block pedestal. Sliding rails are arranged on the outer walls of surfaces, in contact with the sliding block pedestal, of the bending sliding blocks. The sliding block pedestal is connected with the bending sliding blocks through the sliding chutes and the sliding rails. The lower bending module comprises a lower die base and a lower die pedestal, which are arranged in sequence from top to bottom. The bending die is simple in integral structure, and is reasonable in design; the bending sliding blocks are connected with the sliding block pedestal in a sliding manner, and after the four sides of the electric box are bent, a tool can be withdrawn smoothly, in this like, the four sides of the electric box are bent synchronously by using one die, so that the production cost is reduced greatly, the production efficiency is improved, and the product quality is more stable.

The invention provides a lenticular nucleus supporter for a cataract surgery. The supporter is formed by an infusion handle, an infusion tube tail cover, an infusion tube, an infusion rod, a spring, an infusion tube cover, an infusion needle head and an infusion three-jaw. The infusion tube is hollowed, one end of the infusion tube is embedded into the infusion tube tail cover, the other end of the infusion tube is embedded into the rear end of the infusion tube cover, the front end of the infusion tube cover is in a cone shape, one end of the infusion needle head is embedded into the front end of the infusion tube cover, the infusion three-jaw is three thin steel wires, the tail end of each steel wire is fixed with the front end of the infusion rod, the spring is sleeved outside a front section of the infusion rod, a middle section of the infusion rod is adapted to the infusion tube in diameter, and the infusion handle is fixedly connected with the tail end of the infusion rod. According to the lenticular nucleus supporter, the infusion three-jaw is utilized to form a fan-shaped strut in an eye when the laceration of a posterior lens capsule occuring in an ultrasonic emulsification operation so as to support a downfallen nucleus, so that the operation is enabled to be carried out smoothly. The infusion needle head can also be used as an auxiliary hook, and the functions of chopping and rotating the nucleus can be played. The supporter has reasonable design, is simple and convenient to manufacture, adopts metal materials, can be disinfected at high temperature and high pressure, can be used repeatedly, and is low in cost.

When optical disk is placed to tray, first functional force is applied to tray optical drive to overcome a lesser magnetic attraction, when optical disk is not placed to tray, second functional force is applied to tray optical drive to overcome a larger magnetic attraction. Maximum of second functional force is larger than maximum of first functional force.

The invention discloses a helical gear heading mold. The helical gear heading mold consists of an upper die and a lower die, and is characterized in that the upper die comprises an upper die sleeve and a punch, wherein the punch is arranged in an inner hole of the upper die sleeve in a vertically moving manner; the lower die comprises a lower die sleeve and a rotary die body; the rotary die body is rotatably arranged in a cavity of the lower die sleeve through upper and lower planar bearings; an inner hole is formed in the middle of the rotary die body for fixing an alloy die core; the alloy die core is provided with a helical gear heading die cavity; the upper section of the die cavity is provided with a straight hole; the lower section of the die cavity is provided with a helical gear cavity which has the same shape as that of a headed helical gear; the bottom of the die cavity is communicated with a rear through ejector rod guide hole; a rear through ejector rod is movably arranged in the rear through ejector rod guide hole; during cold heading forming of the helical gear, the bottom surface of the upper die sleeve is tightly attached to the top surface of the alloy die core, and the head of the punch extends into the die cavity of the alloy die core. According to the helical gear heading mold, cold heading forming of helical gears on cold heading equipment can be realized, the helical gear machining efficiency is greatly improved, the helical gear machining period is shortened and the helical gear manufacturing cost is reduced.
