  • Publication number: 20230381849
    Abstract: A workpiece processing apparatus comprises a base member formed with a hydraulic chamber fillable with liquid, a punch and a piston. The hydraulic chamber has a workpiece processing chamber and a hydraulic-pressure generation chamber. The punch is movable between an initial position which is apart from the workpiece processing chamber and a received position at which the punch is partially received in the workpiece processing chamber. When the punch is moved from the initial position to the received position, the punch presses the workpiece into the workpiece processing chamber. The piston is partially received in the hydraulic-pressure generation chamber and receives a pressing force directed into the hydraulic-pressure generation chamber in a course of movement of the punch from the initial position to the received position, and the piston is moved in accordance with the pressing force and increases hydraulic pressure of the liquid.

The hydraulic chamber has a workpiece processing chamber and a hydraulic-pressure generation chamber which are coupled together. Each of the workpiece processing chamber and the hydraulic-pressure generation chamber extends in the upper-lower direction and opens upward. The base member comprises a piston which is partially received in the hydraulic-pressure generation chamber. When the slider is moved downward, the punch is moved downward and presses the workpiece into the workpiece processing chamber, and the piston receives a downward force and is moved downward. The thus-moved piston increases hydraulic pressure of the liquid.

  • Patent number: 11815475
    Abstract: The present invention provides a novel method for identifying a molecular structure by a single crystal X-ray analysis. A single crystal that gives an X-ray diffraction spectrum sufficient for determining a structure of a molecule can be efficiently obtained by including a test molecule in a metal complex, and then crystallizing the test-molecule included in the metal complex. By analyzing this single crystal by an X-ray analysis, it is possible to determine a structure of the test molecule without obtaining a single crystal of the test molecule. With the novel method according to the present invention, the structure of a test molecule in a trace amount of a sample can also be determined.
