Abstract: The utility of a call waiting service is enhanced. When telephone A is engaged in voice communication with telephone B, if there is a call from telephone C, the telephone number of the telephones B and C are temporarily stored in a CCB. If the telephone C goes on-hook before the telephone B does, the telephone number of the telephone C is transferred from the CCB to subscriber data and stored as a recall number. Thereafter, when a switchhook operation is performed on the telephone A during communication with the telephone B, an automatic call is made to the telephone C by using the stored telephone number. If the telephone B goes on-hook before the telephone C does, the telephone number of the telephone B is transferred from the CCB to the subscriber data and stored as a recall number. Thereafter, when a switchhook operation is performed on the telephone A during communication with the telephone C, an automatic call is made to the telephone B by using the stored telephone number.

Abstract: A waste-to-energy incineration system, in which the amount and the heat value of exhaust gas changes during operation, includes an incinerator for burning waste, a boiler in the incinerator for generating steam with exhaust heat generated by the incinerator, and a superheater for superheating steam generated in the boiler. A steam turbine is provided which is driven by steam superheated by the superheater and a generator is driven by the steam turbine. A fuel reformer is provided for reforming source fuel. A combustor burning fuel gas reformed by the fuel reformer and at least a part of exhaust gas fed from the incinerator is provided which decomposes generated dioxin in waste incineration exhaust gas.

Abstract: A method for preparing a (meth)acrylic acid ester, which comprises reacting (meth)acrylic acid with a C.sub.1-3 alcohol in the presence of a strongly acidic ion exchange resin as a catalyst, wherein the reaction is carried out under reduced pressure while the molar ratio of the alcohol to the (meth)acrylic acid is adjusted to be less than 1, whereby it is possible not only to improve the esterification yield by one pass but also to reduce the amount of a by-product alkoxypropionate which is problematic in the purification system.

Abstract: In a crystallization method, a liquid mixture containing a crystallizable component is cooled so as to form and separate crystals of the crystallizable component. Then, a purified melt having purity substantially equal to that of the separated crystals, to which a polymerization inhibitor is added and which is heated to a temperature higher than a freezing point of the separated crystals, is circulated to flow contacting the crystals so as to accelerate melting. Then, the melted crystals are recovered along with the purified melt containing the polymerization inhibitor.

Abstract: A method of controlling the scanning of the thermal head to insure uniform printing density. The method comprises scanning thermal sensitive paper with the thermal head in a first direction while supplying the printing signal to the thermal head to thereby effect desired printing, terminating the printing signal after the completion of the printing while continuing the scanning of the paper in the first direction until heat accumulated in the thermal head has dissipated, and thereafter returning the thermal head while in contact with the thermal sensitive paper in a second direction opposite to the first direction. In the alternative, the thermal head can be disengaged from the thermal sensitive paper after the completion of printing a single line until heat accumulated in the thermal head has dissipated, and subsequently returning the thermal head while in contact with the thermal sensitive paper in the second direction. In this manner, the printing density can be maintained at a uniform level.
