摘要:
A work to be exposed to light beams in an exposing section is fitted to an alignment table in an automatic aligning apparatus under the effect of suction caused by a suction unit. Then, cameras for optically recognizing alignment marks in the form of images are displaced to positions where the alignment marks can optically be read through wide transparent windows on an alignment table so that positions representative of displacement of the cameras are taken into position representative of the alignment marks on the work within image receiving regions recognizable by the respective cameras. The alignment table is then displaced in such a manner that the positions assumed by the alignment marks on the work are located in correspondence to preset positions in the exposing section. The apparatus is preferably used for automatically aligning a copper-plated laminar plate to be exposed with a mask film when wiring patterns on a printed wiring board are to be exposed.

In a method for detecting the freezing of water within a fuel cell, precise detection can be performed using a phenomenon specific to the time when water starts to freeze to allow a reduction in erroneous activation. Detection at an early stage after the start of freezing is allowed, and hence measures can be taken against an output reduction before the water within the fuel cell completely freezes.

A source driver supplies a grayscale voltage to a liquid crystal capacitor and a storage capacitor provided in parallel with the liquid crystal capacitor, a voltage that changes in synchronization with a polarity inversion timing being applied to one end of the storage capacitor. The source driver includes an offset value calculation section that calculates an offset value based on grayscale data corresponding to respective color components of one pixel, a grayscale data correction section that corrects the grayscale data using the offset value corresponding to the respective color components, and a source line driver section that drives a source line corresponding to the respective color components based on the grayscale data that has been corrected by the grayscale data correction section. The source line driver section drives the source line corresponding to the respective color components based on the grayscale data that has been corrected by the grayscale data correction section, and then drives the source lines corresponding to the respective color components based on the grayscale data before being corrected by the grayscale data correction section.
