摘要:
Crude N,N'-bis(2,2,6,6-tetramethyl-4-piperidyl)alkanediamine represented by the formula: ##STR1## wherein n is an integer of 2 to 10, is purified by crystallization from a ketone solvent of 3 to 9 carbon atoms. The purified product thus obtained has a purity of 98% by weight or more, a 2,2,6,6-tetramethyl-4-piperidone content of 150 ppm or less, and an initial APHA value of 30 or less. The purified product is also inhibited from discoloration with the passage of time.
摘要:
An information processing apparatus includes circuitry to designate an attribute of an image object to be superimposed with an additional object and perform first identification to identify an image object indicating the attribute designated, among image objects included in image data. The circuitry performs second identification to identify an image object that has not yet been superimposed with an additional object, among image objects identified by the first identification, and generates the additional object to be superimposed on the image object identified by the second identification.

摘要:
A folding machine includes a conveyance roll configured to come into contact with both a first region and the second region being flush with each other; a web guide mechanism configured to cause the first region and the second region to face each other with reference to the folding line so that an angle between the first region and the second region becomes smaller toward downstream; a press mechanism configured to press at least any one of the first region and the second region. The press mechanism changes a pressing strength on the web to change at least either a track length (first track length) in which one side edge provided on a downstream of a conveyance roll is conveyed or a track length (second track length) in which other side edge is conveyed.
摘要:
An elastic thread supply device including a tension controller configured to control the stress acting upon an elastic thread drawn from an elastic thread package, and a drive roll configured to supply the elastic thread dispensed from the tension controller to a processing line. The drive roll operates at a supply velocity slower than a conveyance velocity of a web, and increases or decreases the supply velocity depending on the fluctuation in the conveyance velocity.
