The invention relates to the field of power engineering and, more specifically, to systems for generating electricity based on the use of solid fuel, primarily brown and black coal. In the coal gasification method, a gasifier is fed with a uniform activated coal water fuel, the droplets of which are of equal size and the coal particles in said droplets having a similar granulometric composition. The fuel droplets are introduced intermittently in separate doses of fuel with a certain amount of motion being imparted thereto. The milling of the coal for the activated coal water fuel preparation method is adjusted adaptively according to the criterion of the actual amount of volatile substances given off by the coal, and the coal is thoroughly classified according to its granulometric composition. The invention provides for more extensive recovery of thermal energy from coal and more efficient electricity generation.

Disclosed is a method for performing a liquid processing on a substrate using an aqueous solution of a chemical agent at a predetermined concentration as a processing liquid. The method includes: storing the processing liquid in a processing liquid storage unit; and supplying an aqueous solution of the chemical agent at a different concentration from the concentration of the processing liquid to the processing liquid storage unit, discharging the processing liquid from the processing liquid storage unit so as to update the processing liquid stored in the processing liquid storage unit. The aqueous solution in a predetermined amount is supplied to the processing liquid storage unit, and the processing liquid is discharged from the processing liquid storage unit, the processing liquid containing the chemical agent in the same amount as the amount of the chemical agent contained in the aqueous solution supplied to the processing liquid storage unit.

The invention relates to a five-charge three-discharge storage battery container formation method. The method is characterized by adopting a five charging steps and three discharging steps to complete the container formation and comprising the following steps of first-time charging: charging the storage battery for 3min through the current of 1.8A, and standing for 2h; second-time charging: charging the storage battery for 3h through the current of 1.8A, then charging the storage battery for 14h through the current of 2.4A, and charging the storage battery for 5h through the current of 1.2A; first-time discharging: discharging the storage battery for 2h through the current of 3A; third-time charging: charging the storage battery for 12h through the current of 2.4A, and then charging the storage battery for 5h respectively through the currents of 1.8A and 1.2A; second-time discharging: discharging the storage battery for 2h through the current of 3A; fourth-time charging: charging the storage battery for 10h through the current of 2.4A, then charging the storage battery for 5h respectively through the currents of 1.8A and 1.2A, and standing for 2h; third-time discharging: discharging the storage battery to 10.5V through the current of 6A; and fifth-time charging: charging the storage battery for 4h through the current of 2.4A, charging the storage battery for 5h through the current of 1.8A, charging the storage battery for 5h through the current of 1.2A, charging the storage battery for 3h through the current of 0.1A, and finally extracting the acid. The method is simple in process, a great amount of working hours and energy can be saved, and the economic benefit of enterprises can be improved.

An overmolding process for a hollow receptacle provided with a neck, and an axial body with a shoulder a sidewall and a bottom, the hollow receptacle, having axial height H and larger cross-section S. When the mould is open, the neck bears in contact with an axial support so as to mask the neck during the overmolding process. Before closing the mold, the sidewall is placed in a lateral positioning device that can be moved along an axial direction of the mold. After the mold has been closed, the lateral positioning device is displaced in the axial direction as the material flow injected into the axial cavity and forming an annular flow.

An anti-fatigue manufacturing method of a car transmission gear comprises the steps that forging blanking, heat pretreatment (isothermal normal fire), gear blank processing, gear hobbing, gear strengthening and toughening treatment (the gear part is subject to two times of induction heating and circulatory quenching), modification of criteria to the drawing demand, gear hobbing, gear shaving and gas nitrizing process are carried out in sequence. By adopting the method, 6-grade or more than 6-grade precise car gears can be efficiently produced in batch at low price, and the produced car gears has the bearing/carrying capacity almost as well as that of alloy cemented steel. The car transmission gear manufactured by adopting the method can replace the carburized and quenched gear in the prior art.
