Provided is a substrate positioning device, comprising a datum plane which can transmit substrates one by one and moves horizontally. Firstly, an end positioner stops the movable substrate of the datum plane, and then a side edge positioned contacts with and corrects the substrate of the datum plane, and finally a lifter lifts the substrate to leave the datum plane through movement from bottom up. The device stops and positions the substrate through mechanical assemblies, so as to remove configuration of sensing components.

The invention provides a flip mobile communication terminal, which is used for solving the problems that the conventional flip mobile communication terminal is inconvenient to utilize of a television antenna and easy to be worn and broken, and cannot meet the performance requirements of a communication antenna and the television antenna simultaneously. The flip mobile communication terminal comprises a lower turning cover and an upper turning cover in rotary connection with the first end of the lower turning cover through a rotary connection device. The flip mobile communication terminal further comprises a single-pole communication antenna, a television antenna, an antenna impedance matching network, a low-noise amplifying circuit and a filtering processing circuit, wherein the single-pole communication antenna is arranged inside the first end of the lower turning cover; the television antenna is arranged inside a second end of the lower turning cover; the second end of the lower turning cover is opposite of the first end of the lower turning cover; the antenna impedance matching network is arranged inside the lower turning cover; the low-noise amplifying circuit is arranged inside the lower turning cover and is connected with the television antenna through the antenna impedance matching network; and the filtering processing circuit is arranged inside the lower turning cover. The flip mobile communication terminal is convenient to use and not easy to be worn and broken, and can meet the property requirements of the communication antenna and the television antenna simultaneously.

The invention discloses a proportional pump constant power control method for research and distribution of hydraulic presses, the steps are as follows: Step 1. During the working process of research and distribution hydraulic presses, the proportional pump changes the opening of the spool through the amplifying plate according to the process action to output different flow rates, thereby ensuring The control module judges whether the motor should enter the constant power control according to the running speed and beat of the slider down; step 2, the control module reads the power signal of the instrument, if the actual power P of the motor is equal to or exceeds the rated power P0 for more than 0.3s, then Execute step three, if the actual power P of the motor is less than the rated power P0, then execute step four; step three, the control module collects the pressure information of the slider through the pressure sensor, and outputs the proportional pump flow according to the constant power control method, power = pressure × flow ( P=P×Q), the pressure of the slider continues to rise and the speed is continuously slowed down, so as to ensure the rated power value of the motor and complete the pressing and forming action of the workpiece; step 4, the slider enters the pressure maintaining and subsequent process actions.

The invention relates to a front-end power output structure of a diesel engine. The front-end power output structure comprises a crankshaft fixed on a diesel engine body, and the front end of the crankshaft is sleeved with a crankshaft timing gear. The front-end power output structure is characterized in that the crankshaft timing gear comprises an arc-shaped shaft, one end of the arc-shaped shaft is a large end, the other end of the arc-shaped shaft is a small end, the small end of the arc-shaped shaft extends out of a gear chamber cover, a gear ring is arranged at the large end of the arc-shaped shaft, and the small end of the arc-shaped shaft is sleeved with a crankshaft pulley. An extending-out part is formed by extending outwards in the axial direction of the arc-shaped shaft at the position of the gear chamber cover where the arc-shaped shaft extends out, and a front-end oil seal, a space ring and a front-end bearing are sequentially arranged in a cavity between the extending-out part and the arc-shaped shaft. A concave cavity is formed on the rear end face of the crankshaft pulley, and the extending-out part of the gear chamber cover extends into the concave cavity on the rear end face of the crankshaft pulley. The front-end power output structure is reasonable in structure, flexible to produce, high in output power and load bearing capability and convenient to dismantle.
