摘要： A printer for printing a photograph which includes an exposing portion, a processing portion, a collecting portion, and an optical system is provided. The optical system includes a light source, color filters for color-correcting light from the light source in a light passing area, and a light diffusion box for diffusing the light transmitted from the color filters. The color filters in the optical system each include a pair of opposing filter members for interposing the light passing area. The pair of filter members are installed so as to be movable toward/away from each other and to thereby be superposed/detached. Moreover, the central portion of the opposing front ends of the pair of filter members are convex in the direction of superposition.

摘要： Filter adjustment apparatus for adjusting cut-off frequencies or dip frequencies, for example, may be adjusted to desired optimum properties, during application of an input signal of a constant frequency. The optimum filter adjustment data are found, based on data manifested when the level detected output of the filter output crosses a prescribed reference level whereby the filter adjustment operation is simplified and accuracy is improved with a simplified structure, and it is possible to achieve automatic adjustment of the filter characteristics.

摘要： A novel 5-fluorouracil derivative of the formula: ##STR1## wherein R.sup.1 is a fluorine-containing C.sub.1 -C.sub.10 organic group which optionally contains sulfur, oxygen and/or nitrogen. The novel 5-fluorouracil derivative is useful as a carcinostatic substance, which has a high carcinostatic activity but which is less toxicity against digestive tract and causes less autonomic imbalance than other known 5-fluorouracil derivatives.
