Abstract: A contrast mask for a transparent photographic original may be formed by illuminating a photochromic body (11,41) through the original with white light. Preferably the photochromic body (11,41) is optically neutral (grey) and contains a silver halide as a photochromically active substance. Preferably the mask-forming exposure is performed separately from the photographic exposure of a recording medium through the original and the mask, by a different light source (27). The optical contrast range of the mask can be varied in response to the optical contrast range of the original by varying the amount of the mask-forming exposure. This variation is preferably effected by varying the number of flashes of the light source (27).The photochromic body is preferably incorporated in the holder (1,33) for the transparent original.Photographic reproduction apparatus may include an automatic densitometer, the output of which controls the amount of the mask-forming exposure.

Abstract: The present invention relates to a sheet which may be used in firing ceramic faced base plates, glass faced base plates and metal faced base plates. The sheet comprises a combustible sheet such as a pulp paper and a coating layer coated on at least one surface of the combustible sheet. The coating layer comprises a powder of a material with a high melting point and a powder of carbon which may be formed separately from the layer comprising the powder of a material having a high melting point. The coating layer comprising the powder of carbon effectively prevents shrinkage of the sheet during firing, and thus prevents adhesion between adjacent stacked base plates and between the base plates and the supporting base. The sheet of the present invention further provides a layer of a uniform breadth which prevents the formation of undulations and pin-holes in the base plates during firing.

Abstract: A resist is coated on a photomask and a predetermined pattern is exposed on the resist. The photomask is dipped in a developing solution together with an electrode which exhibits a stable potential in the developing solution, so that a change in current flowing between the photomask and the electrode is detected on the basis of a change in capacitance between the photomask and the developing solution, while developing the pattern formed on the resist. The current abruptly changes (e.g., exhibits its peak) around the time at which the resist is removed and a chromium underlying layer of the photomask is exposed. The time obtained by multiplying the time until the change appears by a predetermined coefficient is regarded as the time corresponding to the end of the developing step.
