Abstract:
There is disclosed a silver halide color photographic material comprising a photosensitive silver halide emulsion layer that contains an acylacetamide yellow dye-forming coupler whose acyl group is represented by formula (I) and a high-boiling organic solvent, wherein the weight ratio of the high-boiling solvent to the coupler contained in said layer is 0.3 or below. ##STR1## wherein R.sub.1 represents a monovalent group, Q represents a group of nonmetallic atoms required to form together with C a 3- to 5-membered hydrocarbon ring or a 3- to 5-membered heterocyclic ring that contains a hetero atom selected from the group consisting of N, O, S, and P, provided that R.sub.1 is not a hydrogen atom and it does not bond to Q to form a ring.
Abstract:
A high-cut and high-blend control voltage generating circuit for activating a noise reduction circuit of an FM stereo receiver is configured to be simply responsive to multipath noises and never to plug noises. A changing and discharging circuit in the control voltage circuit may have a relatively long charging time constant, and the voltage control circuit may be configured to be simply responsive to multipath noises above a predetermined level. Thus the circuit is much less liable to operate erroneously.
Abstract:
An information processing apparatus that calculates a similarity between a plurality of pieces of content stored in a content storage unit, stores content information including information of the similarity obtained by the similarity calculation, generates a virtual three-dimensional display screen for content selection on the basis of stored content information, and allows selection of a piece of content from the virtual three-dimensional display screen.
Abstract:

Abstract:
An information selecting apparatus includes a computer, and makes a user select an arbitrary item from a plurality of items by a direction input of the user. Each of the items is assigned to a direction based on an input frequency, for example. In a case that a direction input is performed by means of a polygonal guide, the items are assigned to directions corresponding to the vertexes of the guide and directions corresponding to the parts except for the vertexes. For example, a high-frequency item is assigned to the direction corresponding to the vertex, or a range of the direction assigned to the high-frequency item is relatively made larger. Furthermore, when a direction corresponding to the vertex is input, items assigned to the parts except for the vertexes may temporarily be assigned to other vertexes. In addition, when predetermined operation data is input, the items of the directions corresponding to the vertexes and the items of the directions corresponding to the parts except for the vertexes may be interchanged.
