Abstract: A region of a side surface of a tip part of a spindle, the region being opposed to an inside surface of a cover with a gap therebetween, is formed with a groove going round the spindle one time. At a location where the groove is formed, the sectional area of the gap between the tip part and the cover is enlarged. Hence, the gap between the tip part of the spindle and the cover can be expressed as a space (passage) in which a small sectional area and a space (expansion chamber) having a large sectional area are alternately disposed. If processing liquid containing processing swarf enters into the gap, the processing liquid is not likely to enter into the passage. Deposition of the swarf onto the tip part of the spindle is restrained, making it possible to reduce the frequency of cleaning of the tip part.

Abstract: A method of correcting print images in an electrophotographic printer wherein an image formed by a print head (3) on a peripheral surface of a photoconductor drum (1) is transferred and printed on a sheet of paper. The method comprises: furnishing the print head with a standard tacho signal in the form of pulses and thereby printing on a sheet of paper a check mark (9) for each given number of pulses of the standard tacho signal while the photoconductor drum makes one rotation; by means of a camera (10), detecting a periodic deviation in each spacing between successive such check marks; in response to the deviation in each spacing between the successive check marks, varying the pulse width of pulses of the standard tacho signal for each spacing between the successive check marks, thereby to provide a modified tacho signal; and effecting printing thereafter based on the modified tacho signal.

Abstract: A electronic photograph printer includes a density-measurement section and a density controller section. The density-measurement section includes a density sensor 31 for measuring densities of images printed on a web by electronic-photograph-printing units. The density controller section adjusts densities of images which are about to be printed on the web by the electronic-photograph-printing units based on measurement data obtained by using the density sensor 31 associated with the densities of the image on the web. This configuration enables accurate and stable print-density control at a low cost.

Abstract: To cut a protecting sheet adhered over the obverse of a wafer, an inclination angle of a cutting tool is adjusted according to a form of a chamfered part of the wafer and a finishing thickness of the wafer so that the protecting sheet is cut into the required minimum size for protecting the obverse of the wafer. Thus, the protecting sheet is not included inside a removed portion in a grinding process of the reverse of the wafer with a grindstone even if the wafer is ground to have extremely thin finishing thickness. Hence, the protecting sheet is not ground while the reverse of the wafer is ground, and the grindstone is thus prevented from being clogged up with ground material of the protecting sheet.
