Abstract: A robot device according to an embodiment of the present disclosure includes: an input acceptor configured to accept an input to a robot device; an expression content decider configured to decide a set of expression contents in which the expression contents are associated with each other, the expression contents each indicating a response of the robot device with respect to the input; and the signal generator configured to generate an instruction signal that causes another device other than the robot device to execute an operation corresponding to one portion out of the set of expression contents.

Abstract: 5-Fluorouracil derivatives of this invention are represented by the general formula: ##STR1## wherein R indicates an alkylene group having 1-8 carbon atoms, A indicates an atomic group of --NH-- and --CO--, n is 0 or 1, and Y indicates an alkyl group having 1-10 carbon atoms, an aryl group, a heteroaryl group, a pyridinium ion having a halogen as a pair ion or an isocyanate group.These derivatives are useful as anticancer medicines and intermediates therefor.These derivatives are produced by six specified methods of this invention. A representative method is a process which comprises reacting 5-fluorouracil and an isocyanate represented by a general formula:Y--(A)n--R--NCO (VII)wherein R, A, n and Y are the same as those indicated in the formula (I).

Abstract: A commercial method for producing 2,3,3-trimethylindolenine useful as an intermediate for cationic dyes, etc., with a high yield is provided, which comprises mixing aniline with 3-chloro-3-methylbutane-2-one in a mixing ratio by mol of 3:1-10:1; reacting the resulting mixture at a temperature of 50.degree.-150.degree. C. for 2-20 hours; thereafter elevating the temperature of the reaction liquid; and maintaining the liquid at a reflux temperature of aniline for 0.5-2 hours to complete the reaction.
