  • Patent number: 6853941
    Abstract: Methods and apparatus, including computer program products, implementing and using techniques for open-loop waveform acquisition. In general, in one aspect, the invention provides a method for open-loop waveform acquisition. The method includes acquiring an S-curve of an acquisition loop of an electron-beam probe system. The S-curve represents a response of the acquisition loop to changes of potential differences between the acquisition loop and a device under test. The method includes calibrating the acquisition loop to obtain a linear region in the acquired S-curve and using the linear portion of the acquired S-curve to calculate voltage at a probe point of the device under test.

  • Patent number: 4285659
    Abstract: The present invention relates to a mold device for an injection molding machine which consists of an injection machine and a mold device. The mold device is divided into two portions, namely, a mounting portion and a molding portion, which are designed so that they may be handled individually and/or integrally. The present invention further provides an arrangement in which the molding portion may be installed on the mounting portion with considerable transverse tolerance, despite employment of a hot runner system therein.
