The invention can be basically described as a gasket for converting a standard mechanical joint to a restricted mechanical joint without changing the configuration of the bell, plug or gland of the joint and without additional fittings or equipment. In the practice of the present invention, the bell and gland configuration of a standard mechanical coupling can be used to connect the plug end of one length of pipe to the bell end of another length of pipe in a constrained relationship that exceeds more than The force of friction of the rubber against the tube. In a more specific discussion of the taught embodiments, the invention includes forming the liner to fit within the bell in such a manner that during rest there is a void or groove in which the liner compresses, which in turn affects slice rotation. In this way, the configuration of the pads affects the synchronization and degree of rotation throughout the process of securing the gland to the bell.

The invention discloses a surface microphone calibration device, in particular relates to a calibration device specifically designed for special microphones such as surface microphones, and belongs to the field of calibration of microphones. Aiming at the special nonstandard flat type structure of the surface microphone, the device is designed with a new flat type asymmetrical short coupled cavity structure, a flat large-diameter gland structure, and an independent and simplified surface microphone sleeve cover structure, thus consistency and airtightness of sound fields of receivers of the surface microphone and the standard microphone are ensured, and the universality of the device for different sizes of surface microphones is ensured. Compared with the universal calibration device of the existing conventional microphone, the calibration device is specifically applied to the surface microphone, and can improve the calibration accuracy of the surface microphone, and the universality of the device can be improved.

The invention discloses a double chip and double seat checking-valve without washing, which is characterized by the following: comprising gland, access flow passage, outlet flow passage and valve body of valve seat; connecting bottom end of valve rod A (1)to valve chip A (2)as the gland structure; penetrating valve rod B (3)through the hole in the valve chip A (2); connecting spring (4)to valve chip B (5); connecting one end of valve rod C (6)to the valve chip A (2); connecting the other end to valve chip C (7). This invention possesses the advantages of long age and simple structure.

The invention discloses a method for enlarging the field of view of an optical engine. The method is realized by pressing a pressing plate of a transparent quartz observation window of an extended piston and a pressing cover of a transparent material with bolts. The transparent material of the gland is made of plexiglass, and the material of the pressure plate is made of aluminum. The application of the transparent material gland can expand the internal field of view of the combustion chamber in the cylinder to the entire combustion chamber space. The transparent material gland can be replaced according to different combustion chamber structures, that is, it can be designed in the shape of a constricted mouth, a straight mouth and an open combustion chamber. The mechanism of spray impingement on the wall and the influence of different combustion chamber structures on spray development, mixing, combustion and emission are thoroughly studied to meet the needs of different optical tests.

The invention relates to washing machines, in particular to a control method for washing quilts by the washing machines. The method includes the following steps that water is fed to a set washing water level while an intermittent rotation of an impeller inner barrel and an internal circulation spray are performed; the impeller is in the intermittent rotation, and the quilts are washed while the internal circulation spray is performed; an intermediate dewatering is performed; water is fed to a set rinse water level while the impeller inner barrel is in the intermittent rotation; the impeller is in the intermittent rotation, and the quilts are rinsed; and the intermediate dewatering, rinse water feeding and rinsing are repeated, and the final dewatering is performed. The invention further relates to a washing machine using the control method. The spraying is performed by means of an internal circulation pump, the washing is performed by the aids that the cycle of starting and stopping of a motor is prolonged and the starting and stopping of the motor are alternately changed, and three-time rinsing at a medium high water level and a gland structure are utilized, so that when the quilts are washed by the washing machines, the cleaning ratio is high, the rinsing effect is good, the abrasion is slight, and the individual needs of consumers are met.

The invention discloses application of dioscin which has the acute gastrointestinal injury protecting effect and can be prepared into acute gastrointestinal injury protecting medicine.An MTT method and morphological observation prove that the dioscin has the obvious protecting effect on GES-1 cells, Caco-2 cells and IEC-6 cells which are injured by in-vitro hypoxia and reoxygenation; meanwhile, the dioscin has the obvious down-regulation effect on MDA and MPO increasing caused by an acute gastrointestinal injury and has the obvious up-regulation effect on T-SOD and GSH-PX decreasing.After intervening is performed with the dioscin, the phenomena that the injury index of the ischemia reperfusion injury gastric mucosa is increased, the gastric mucosa is eroded and bleeds, and the partial gland structure is disordered are obviously improved, and the phenomena that after an ischemia reperfusion injury is generated, villus falling is obvious, the blood capillaries are expanded, gland damage is obvious, and parts of the glands bleed and are ulcerated are obviously improved.The dioscin can be prepared into the medicine by serving as a single effective ingredient and also can be prepared into a compound preparation by being cooperatively used with other medicine according to the clinical medication requirements.

The invention relates to an ultra-wideband breast tumor imaging method based on magnetic resonance image compensation. The method comprises the following steps of based on a MRI slice atlas based on breasts, constructing a three-dimensional discrete breast model of a gland; modeling a gland structure and approximating structures of gland tissues in the breasts into an elliptic cone shape; using spatial coordinate transformation and ''righting'' an elliptic cone to an auxiliary coordinate system; creating an isosceles triangle area in a plane projection area of the elliptic cone, carrying out a finite element on the area and determining an elliptic cone surface capable of best describing a change trend of a rough gland surface; and carrying out microwave propagation time error estimation and accurate imaging. In the invention, ultra-wideband breast tumor imaging can be accurately performed.

The invention discloses a multifunctional schoolbag. The multifunctional schoolbag comprises a schoolbag body and a water cup pocket, wherein a lifting structure, a limiting structure and a sealing gland structure are arranged at the opening of the water cup pocket; the lifting structure comprises a spring, a rack and a support block; the support block is in slide connection with an inner wall ofthe opening of the water cup pocket; the limiting structure comprises a rotary shaft, a gear combination and a limiting rod; the rotary shaft is arranged at the opening of the water cup pocket; the gear combination comprises a bull gear and a pinion, the bull gear is meshed with the pinion; a through hole is formed in the opening of the water cup pocket; the limiting rod is in slide connection with an inner wall of the through hole; the limiting rod is provided with rack teeth. By adopting the multifunctional schoolbag, a structure matched with the water cup is arranged at the opening of the water cup pocket of the schoolbag, when water cup is not put into the water cup pocket, the schoolbag cannot be taken out from a desk or other slots for accommodating the schoolbag, so that the problemof loss of a water cup due to forgetting is solved, and unnecessary trouble is avoided.
