The repetitive shock irritation device and the shock irritation method disclosed by the invention can be widely used underground repetitive shock irritation in oil and gas well drilling operations in which signals are required.

The invention discloses a corner supporting thin-wall shell structure which comprises a shell structure body. The shell structure body is formed by connecting a plurality of panels. Connecting corners of every three adjacent panels are connected through a corner supporting component, the corner supporting components comprise corner supports, each corner support comprises three intersection faces, each intersection face is provided with a connecting hole position, and every three panels are fixedly connected with the corresponding three intersection faces through bolts. Through the corner supporting structure, the overall rigidity of the thin-wall shell structure can be improved, the relative position relation between the panels of a shell can be guaranteed, the number of screw holes in the outer surface can be reduced, the appearance is made to be changeable, and the period feel is achieved.

The invention discloses an integrated cover sorting and arranging mechanism for an automatic can seamer. Only one driving air cylinder is used as a power source; and sorting and arranging operation for abnormally-shaped can covers in square, polygon and the like is realized at the same time. The integrated cover sorting and arranging mechanism comprises a stander, a cover bin part, a sliding boltpart, the driving air cylinder, a can body clamp and a can cover positioning baffle plate, and is characterized in that: a small sliding bolt capable of sliding forth and back along a large sliding bolt and a cover sorting fork which is positioned at the front end of the large sliding bolt and capable of sliding up and down are arranged in the sliding bolt part; inclined surfaces which are matched with each other are formed at the front end of the small sliding bolt and in the middle of the cover sorting fork; and when the small sliding bolt moves forwards relative to the cover sorting fork, the cover sorting fork is forcibly pressed down. An aim of sorting and arranging covers is fulfilled by using only one air cylinder; and the system has a simple structure, is convenient to control, and has high work efficiency.

In the self-service bill processing terminal and its bill processing method described in the present invention, execution information is input through an input module, and then converted into execution instructions by a main control chip circuit. The bill scanner scans the bills and displays them in the display module. The scanned bills fall into the bill temporary storage component, waiting for the user’s confirmation on the operation component side. The main control chip circuit commands the limit device to perform an opening action, takes out the bill through the bill exit window, and terminates the bill processing flow. If the bills in the bill temporary storage component are correct, the main control chip circuit sends an opening command to the baffle, the baffle opens, and the bills fall into the bill storage platform under the action of gravity for storage. The mechanical structure is simple and reliable. If the bill is found to be wrong, it can be taken out under the control of the user. After the bill is taken out, the bill processing process will be terminated immediately, so as to prevent the process from continuing and the paper bill from being damaged.
