Abstract: A medicament for treatment of cancer comprising a compound represented by the following general formula (I) or a physiologically acceptable salt thereof: Ar1—S—R1—S—Ar2 wherein R1 represents a nonmetal bridging group; Ar1 and Ar2 independently represent a group selected from the group consisting of an aryl group which has, on its ring, one to three hydroxyl groups optionally substituted with a monovalent group and said aryl group may have one to three substituents other than hydroxyl group on its ring; and a heteroaryl group which has, on its ring, one to three hydroxyl groups optionally substituted with a monovalent group, and said heteroaryl group may have one to three substituents other than hydroxyl group on its ring.

Abstract: An imaging signal obtained from CCD is supplied to the pre-processing circuit to form the pre-processing signal consisting of a luminance signal and a color signal and the pre-processing signal is supplied in turn to the post-processing circuit to form the post-processing signal to be outputted to the external circuit or to be recorded. The circuits from CCD to pre-processing circuit are driven by the first clock CKH or the second clock which is slower than the first clock, while the post-processing circuit is driven by the first clock. A clock exchange circuit is provided between the pre-processing circuit and the post-processing circuit, and when the circuits up to the pre-processing circuit are driven by the second clock, the clock exchange circuit is operated to supply the pre-processing signal exchanged to the first clock from the second clock is supplied to the post-processing circuit. Thereby, the post-processing circuit can used in common.

Abstract: A picture signal recording device for recording color video signals having a color signal detection circuit detects the quantity of motion of chroma signals from an inter-frame difference between a color difference signal from a chroma recording processing circuit and a signal delayed by one frame from the color difference signal. A dynamic change smoothing filter circuit smoothes sudden changes in the quantity of motion of the chroma signal. A luminance signal motion detection circuit detects the quantity of motion of chroma signals from an inter-field difference between a luminance signal from a luminance recording processing circuit and a signal delayed by one field from the luminance signal. A maximum value detection circuit detects the maximum value of the quantity of motion of the chroma signal and the quantity of motion of the luminance signal. An adaptive processing circuit controls the quantity of transmission of the sub-Nyquist sampled color signal depending on the maximum value.
