The invention relates to an article having a single-layered or multilayered main body having elastic properties, in particular an air spring bellows, a metal-rubber element or a vibration damper.

To improve the flame-retardant properties the main body of the article consists of or contains at least one layer D which is constructed from a rubber mixture which is free from halogen-containing flame retardants and contains at least one carbon black having a BET surface area according to DIN-ISO 9277 between 35 and 140 m.sup.2/g and an oil absorption number (OAN) according to ISO 4656 between 70 and 140 ml/100 g.

Provided is a sensor comprising a non-conductive substrate; and a conductive layer electronically printed on one side of the substrate, wherein the conductive layer comprises: an antenna pattern for transmitting and receiving a radio signal with an external device; a sensing electrode connected to the antenna pattern via a circular wiring for sensing an impedance change due to contact with a sensing target material; and a coating electrode stacked on the sensing electrode for removing an occurrence of noise of the impedance change. Accordingly, the present invention solves the problem of a sensor, in the form of a terminal, not being compact and the problem of high manufacturing costs and low manufacturing quality of a sensor manufactured using a deposition method in order to replace such sensor with a sensor manufactured by a printing method, and solves a corrosion problem of a sensing electrode, a durability problem, etc. that may occur in the sensor of the printing method.

Provided is a gravure printing method by which high printing density and excellent highlight suitability are obtained, even if a gravure plate having high resolution and reduced thickness is used. The gravure printing method comprises: using an aqueous ink having a Zahn cup #3 viscosity at 20 C. of 11.0 seconds or more and 20.0 seconds or less, and having an evaporation rate of 30 mass % or less in a drying test, the drying test involving drying 1 g of the ink at a temperature of 40 C. and an air flow of 1,400 L/min for 30 minutes; and transferring 1 ml/m.sup.2 or more and 7 ml/m.sup.2 or less of the ink onto a printing medium.

An optical fiber ribbon manufacturing device includes: fiber-supplying units that respectively supply optical fibers; a printing device that prints a mark on each of the optical fibers; and a ribbon-forming device that manufactures an optical fiber ribbon by connecting the optical fibers on each of which the mark has been printed. The printing device includes: a supplying roller that supplies an ink; and a printing roller that includes a printing pattern on a surface thereof and that prints the mark on each of the optical fibers that are lined up in a width direction of the optical fibers by causing the ink supplied from the supplying roller to adhere to the printing pattern and transferring the ink onto the optical fibers. Projections and depressions are disposed on a surface of the supplying roller. The surface of the supplying roller opposes the printing pattern of the printing roller.

There is described a sheet-fed printing press (1000; 1000*) comprising at least two printing units (200; 200.1, 200.2; 200.1*, 200.2*) located one after the other, each printing unit (200; 200.1, 200.2; 200.1*, 200.2*) being adapted to carry out simultaneous recto-verso printing of the sheets (S) and including two printing cylinders (105, 106) cooperating with one an other and forming a printing nip, the two printing cylinders (105, 106) each collecting ink patterns from at least two associated plate cylinders (15A, 15B, 16A, 16B) wherein the two printing cylinders (105, 106) are located one above the other such that the sheets (S) travel laterally through each printing unit (200; 200.1, 200.2; 200.1*, 200.2*) from a first lateral side (201 a; 201 a*) located upstream of the printing nip to a second lateral side (201 b; 201 b*) located downstream of the printing nip, wherein a number of at least two sheet transfer elements (110, 120, 95) is provided downstream of the printing nip of a first one (200.1; 200.1*) and upstream of the printing nip of a second one (200.2; 200.2*) of the at least two printing units (200.1, 200.2; 200.1*, 200.2*) to transfer the sheets (S).
