摘要:
Method and apparatus for the surface-hardening treatment of a synthetic resin shaped article is provided, wherein the shaped article is dipped in a surface-hardening solution; the shaped article is gradually pulled up therefrom thereby to be coated with the surface-hardening solution; and the coated article is irradiated with ultraviolet rays to cure the coating. The shaped article is dipped in succession in a washing tank, a drying tank having warm water or an organic solvent and a hardening solution tank while the shaped article is conveyed by a first conveyor, and then, the shaped article is transferred from the first conveyor through an intermediate conveyor to a second conveyor whereby the shaped article is conveyed to an ultraviolet ray-curing step. The shaped article is introduced to and withdrawn from the respective steps in the state where the shaped article is hung on a hanger, and one or a plurality of hangers are attached to each of a plurality of portions of the first conveyor so that the shaped articles are simultaneously subjected to the dipping treatment in the respective tanks, whereas the hangers are conveyed one by one from the intermediate conveyor to the second conveyor where the shaped articles are separately hung. In each of the tanks, organic solvent and the hardening solution tank, the liquid is overflowed therefrom and circulated via a filter to each tank. The surface-hardening treatment is carried out under such conditions that the hardening solution and the atmosphere above the hardening solution tank are maintained at room temperature and the dew point of said atmosphere is maintained at least 3.degree. C. lower than the temperature of the hardening solution.

A recording medium for sublimation type heat-sensitive transfer recording process, in which an image receiving layer comprising a resin composition containing a dyeable resin and at least one phosphite antioxidant shown in Formulas (1), (2), or (3) is formed on a substrate surface. This recording medium for sublimation type heat-sensitive recording methods has extremely superior light resistance, and the image recorded on this recording medium suffers little fade out or discoloration as a result of exposure to light, so that this recording medium is expected to contribute greatly to the spread of video printers and the like. ##STR1## (In Formula (1), R.sub.1 and R.sub.2 represent H or an alkyl group having a number of carbon atoms within a range of 1-20, R.sub.3 and R.sub.4 represent alkyl groups having a number of carbon atoms within a range of 1-20, X represents H or an atomic group having 1-10 carbon atoms as a main skeleton thereof, and n has a value of 1, 2, 3, or 4.) ##STR2## (In Formula (2), R.sub.5 and R.sub.6 represent H or an alkyl group having a number of carbon atoms within a range of 1-20, R.sub.7 represents an alkyl group having a number of carbon atoms within a range of 1-20, Y represents H or an atomic group having 1-10 carbon atoms as a main skeleton thereof, and n has a value of 1, 2, 3, or 4.) ##STR3## (In Formula (3), RS, R.sub.9, R.sub.10, and R.sub.11 represent H or an alkyl group having a number of carbon atoms within a range of 1-20, Z represents H or an atomic group having 1-10 carbon atoms as a main skeleton thereof, and n has a value of 1, 2, 3, or 4.)
摘要:
Disclosed is a recording media for a sublimation-type heat-sensitive transfer recording process. The purpose of the present invention is to supply a recording media for a sublimation-type heat-sensitive process possessing an extremely high whiteness degree. The recording media comprises an image receiving layer composed of a dyeable resin which can be dyed by a sublimable dye; a crosslinking agent; and an anthraquinone based bluing agent. With the recording media for a sublimation type heat-sensitive recording process according to the present invention, a recording media having a high whiteness degree which does not turn yellow following curing can be obtained. As a result of the high whiteness degree of the foundation, this recording media is of an extremely high grade, and due to its extremely vivid recording image, it will be widely adopted and marketed in video printers.

Provided is a data replication method capable of reducing the number of communication times when a processing result of an active system is replicated to a standby system. The data replication method, in which a first computer receives a first message containing a first processing request, and a plurality of second computers replicates the first message, includes the steps of: sending, by a third computer, the first message to the first computer and the second computers; sending, by each of the second computers, a message receive notification of the first message to the first computer; sending, by the first computer, after reception of the message receive notification from the second computers, the message receive notification of the first message to the third computer; and sending, by the first computer, a notification indicating that the first processing request becomes executable by the first computer to the second computers.
