Title: Load port door assembly with integrated wafer mapper
Inventor: MEYHOFER ERIC
IPC: H01L21/00
Filed: 2000-06-20
Granted: 2002-11-21
Abstract: A load port interlace for determining the presence or absence of wafers in a cassette, i.e. a wafer mapper, is integrated with a port closure assembly in a load port interface separating a process environment from an operator environment. A cover plate and a door are arranged in an L-shape, with both members being able to seal the port in a bulkhead of the load port interface. In one configuration, the cover plate seals the port, while door panel members rest horizontally on the operator side of the bulkhead. In this position, a wafer stack, W, inside of a cassette may be placed on the inside door panel, with the top of the wafer stack, W, being open. As the door is raised from the horizontal position to a vertical position, the wafer stack, W, is rotated through an opening in the bulkhead so that the wafer stack, W, is now on the process side. The wafer mapper features a moveable trolley connected to, or within, the door. The trolley can move parallel to the wafer stack, W, under control of a stepper motor and examine each row of the stack, counting wafers as light is reflected or scattered from the edges of the wafers. Each wafer may be optically probed through a window in a cover plate and characteristic signals may be plotted to provide subsequent wafer manufacturing operations with wafer locations. A movable air knife on a side of the window opposite the trolley is magnetically coupled to the trolley and is moved together with the trolley in order to clear the window of liquid droplets from the process environment. When the load port interface positions the cassette and wafer stack, W, in the process environment, a fine spray of liquid droplets may be directed about the wafer stack, W.

Title: Method for fast charging of a battery
Inventor: YAMASHITA TAKAHIRO
IPC: H02J7/00
Filed: 2000-11-22
Granted: 2002-02-01
Abstract: The present invention is to charge the over-discharged battery quickly and correctly, so that it is fully charged. In the fast-charging method of the present invention, full-charge state is determined on the basis of a peak battery voltage or a decrease ΔV in the voltage of the secondary battery 1 after the peak voltage. At the beginning of the fast-charge process, an initial battery voltage is measured. In case where the initial voltage is higher than a preselected voltage, the battery is fast-charged with a normal fast-charge current. In case where the initial voltage is lower than the preselected voltage, the battery is fast-charged with a restricted fast-charge current that is weaker than the fast-charge current.

Granted: 2002-08-21
Abstract: A method for tuning a dielectric filter comprises determining filter characteristics of a filter including a cut-on wavelength and a cut-off wavelength taken at a selected gain level. The filter Is rotatably attached to a collimator assembly and a light source having a wavelength approximately equal to the cut-on frequency Is applied to the filter and rotated to adjust the filter to the cut-on wavelength, and the spectral performance Is measured and compared and compared with a cut-on rating value. The method further includes applying a light signal having a wavelength set to a cut-off wavelength, to the filter rotating the filter relative to the collimator assembly, measuring spectral performance, and comparing the measured spectral performance with a cut-off rating value. The light source having a wavelength set to the cut-on wavelength is reapplied to the filter, and the difference in measured spectral performance with the rating values for each of the low cut-on wavelength and high cut-off wavelength are compared to determine if the difference is within an acceptable range. The steps are repeated until the difference is within an acceptable range and the filter is thus fixedly attached to the collimator assembly to complete the resultant filter.
