  • Publication number: 20250171225
    Abstract: Various trash can assembly embodiments are disclosed. In some embodiments, the trash can assembly includes a body and a lid assembly. The lid assembly can include a lid, and a multicomponent trim ring. The lid assembly can be rotatably connected with the body via a hinge unit. In certain embodiments, a flange of the trim ring is guided into and/or received into the hinge unit. A translating pin of the hinge unit can engage into the flange, thereby providing a rotatable connection between the trim ring and the body. In various embodiments, the translating pin is coupled with a handle to facilitate movement of the pin by a user during engagement of the trim ring and the hinge unit. A positioner can help to position the trash can against or adjacent to a wall or other structure. The movement of both the trim ring and the lid can be dampened.

  • Publication number: 20250093278
    Abstract: In a method for inspecting pattern defects, a plurality of patterns are formed over an underlying layer. The plurality of patterns are electrically isolated from each other. A part of the plurality of patterns are scanned with an electron beam to charge the plurality of patterns. An intensity of secondary electrons emitted from the scanned part of the plurality of patterns is obtained. One or more of the plurality of patterns that show an intensity of the secondary electrons different from others of the plurality of patterns are searched.

  • Publication number: 20250030338
    Abstract: A three-phase resonant converter includes a three-phase transformer, an input bridge arm assembly, an output bridge arm assembly, and a control unit. The input bridge arm assembly has three input switch arms, and each input switch arm has an upper switch and a lower switch. The output bridge arm assembly has three output synchronous rectification switch arms respectively coupled to the three secondary-side windings. Each output synchronous rectification switch arm has an upper rectification switch and a lower rectification switch. The control of each output synchronous rectification switch arm is corresponding to the control of each input switch arm. The control unit controls the upper rectification switch or the lower rectification switch to be turned on with a leading phase angle to the corresponding upper switch or the lower switch so as to maintain an output voltage of the resonant converter to be higher than a voltage threshold.

  • Publication number: 20240386768
    Abstract: A bill receiving box includes a box body having a bill pressing opening intercommunicating with a receiving space of the box body for receiving bills. Front and rear pressing boards are slidably received in the receiving space and spaced from each other. Front and rear springs are disposed in the receiving space of the box body. Two ends of the front spring respectively abut against the front pressing board and the rear pressing board. Two ends of the rear spring respectively abut against the rear pressing board and a rear end of the box body. The rear spring biases the rear pressing board and the front spring forward, and the front spring biases the front pressing board forward, such that the front pressing board presses the bills forward to abut against a rear side of the bill pressing opening. The receiving space receives at least 700 sheets of stacked bills.

  • Patent number: 11926149
    Abstract: A printer includes a paper roll, a printing device, a paper cutting device, a paper output device, and a panel, which are disposed, from rear to front in sequence, on a frame. The printing device includes a printer seat on which a printer head, a paper delivering roller, and a guiding member are disposed. The guiding member forms a paper insertion gap between a guiding piece and a printer seat. The paper insertion gap can smoothly guide a front end of a paper sheet to be inserted downwards to contact with a paper delivering roller. Then, the guiding member pivots back to a positioned state. Thus, the paper sheet can be conveniently and rapidly installed. A paper guiding gap is formed between at least one guiding roller and the printer seat. The paper delivering roller can reliably pull the paper sheet to pass through a printer head for printing.

  • Patent number: 11813855
    Abstract: A barcode printer includes a frame on which a paper receiving device, a printing device, a cutting device, and a paper output device are disposed. The paper receiving device receives a plurality of printing papers which is interconnected and folded in a zigzag manner. A front edge of the uppermost printing paper is inserted downward into a paper inlet passage of the printing device. A paper delivering motor moves the uppermost printing paper forward to pass through a gap between a printer and a paper delivering roller. A printer is activated to print a barcode on a lower face of the uppermost printing paper. The front edge of the uppermost printing paper is moved to pass through the cutter and the paper output roller unit. The paper delivering motor is then stopped, and a rear edge of the uppermost printing paper is cut under operation of a paper output motor.
