As a result, a signal detecting section 17 detects a scanning signal (a first scanning signal) corresponding to a pattern formed on the photomask 12. The detected scanning signal is supplied to a defect judging section 19, together with a scanning signal (a second scanning signal) generated by a reference signal (generating section 18 on the basis of design data employed to form the pattern which is under inspection. The defect judging section 19 obtains a reference value from the reference signal generating section 18 in correspondence with a measuring position, the reference value being calculated on the basis of resolution characteristics of the sensor, and the section 19 calculates a difference between the reference value and the measured value obtained from the signal detecting section 17.

IPC: G03G7/00
Filed: 1982-05-24
Abstract: PURPOSE:To obtain transfer paper superior in fixability, by setting the bulk density of the transfer paper to a specific value or higher. CONSTITUTION:Though sheets of paper are made normally with a bulky density of 0.70-0.82 in consideration of the paper making efficiency, the stiffness, the opaque property, etc., the linear pressure of the wet press and a machine calender of a paper machine is raised or the smoothing treatment due to a super calender is intensified after coating a paint on raw paper to enhance the bulk density of raw paper in the finishing stage, and a transfer form suitable for purposes is obtained. If the transfer form has <0.85 bulk density and is bulky, pressure is consumed to compress the form and does not contribute to the compression of toner particles effectively, and the fixability is low. It is desirable that a resin compatible with a binder of the toner is used as the paint coated to raw paper and has a high electric resistance by itself. For example, an ester acrylate polymer, a polyvinyl acetate, or the like is used as this resin.
