摘要： PROBLEM TO BE SOLVED: To uniformly and sufficiently humidify entire faces of printing papers, by providing a printing paper-humidifying apparatus set in a cooling apparatus of a rotary printing machine with a porous hollow roller which can be close to and away from a printing paper-cooling cylinder and, a water feed system supplying water to a hollow part of the hollow roller. SOLUTION: A printing paper (web) is sent and supplied to a cooling apparatus 1 through a drying apparatus and transferred to a folding machine of a next process at a predetermined speed with keeping touch with cooling cylinders 2 and guide rollers 3 in the cooling apparatus 1. Each cooling cylinder 2 is provided with a humidifying apparatus which has a hollow humidifying roller 5 and a water feed system 6 supplying water to a hollow part 5a of the humidifying roller 5. When the humidifying roller 5 is rotated in pressed touch with the cooling cylinder 2, the water is fed to the cooling cylinder 2, thereby humidifying the printing paper. The humidifying roller 5 preferably uses a porous material of physical properties values of a pore diameter of 70-140 μm, a porosity of 60-96%, a thickness of 12.5-50 mm and a 25% compression stress of 100 g/cm or larger.

摘要： PROBLEM TO BE SOLVED: To provide a heat cycle engine utilizing a heat pump that can improve the heat efficiency of the engine by lowering the temperature of a low- temperature heat source. SOLUTION: This heat cycle engine has a heat engine which works by using a working fluid, a working fluid evaporating means which is installed on the upstream side of the heat engine and evaporates the working fluid by heating the fluid through a high-temperature heat source, and a working fluid condensing means which is installed on the downstream side of the heat engine and condenses the working fluid by cooling the fluid through the low-temperature heat source. This engine also has a circulating means which circulates the working fluid among the heat engine, working fluid evaporating means, and working fluid condensing means. The low-temperature heat source constitutes an adsorption/desorption type heat pump equipped with an adsorbent and provides a temperature lower than an ordinary temperature by utilizing the latent heat caused by the adsorption medium adsorbing/desorbing actions of the adsorbent.

摘要： PURPOSE:To prevent hot air from remaining in a pocket area by providing on a pocket box a central discharge opening arranged in parallel with slits on both sides and opens ranging to upper and lower surfaces of the box, and a loophole which opens at the upper surface of the box. CONSTITUTION:A hot air to be discharged from slits 3 flows to the center of a nozzle by the Coanda effect due to a curved face 5 at a slit outlet. At the same time, a hot air to be discharged from a central discharge opening 17 is discharged vertically due to a preliminary running interval between upper and lower faces of a box 4. Among the discharged hot airs, the hot air which flows toward a pocket area 11 enters boxes 14a and 14b through a loophole 18. The hot air which flows toward both sides of a one-way nozzle to be discharged into a dryer from opened both ends flows along a web 6, thereafter, discharged in the dryer through a hot air loophole 10. Thus, retention of the hot air in the pocket area 11 is prevented so that a distribution of the local heat transfer rate to be obtained from the nozzle will be improved. As a result, the length of the dryer can be shortened.

摘要： PROBLEM TO BE SOLVED: To provide a casting drum composed of a Cu-alloy made sleeve and an SUS-made core light in weight, free from the sliding of a fitting part in thermal loading, and long in durable life, in a twin drum type continuous casting drum used for twin drum type continuous casting equipment. SOLUTION: By constituting the SUS made core, which is fitted into a Cu- alloy made sleeve, of ring-shaped cores juxtaposed in the axial direction with a space with one another as a plurality of splitted bodies, the sleeve is movable in the axial direction at the part where the core does not exist, and the relative sliding on the fitting part becomes hard to be caused at the part where the core exists owing to that the length in the axial direction of the fitting part of the sleeve and the core is cut to be short, as a result, enabling the tightening force to be small in fitting of the sleeve and the core, which enables the sleeve to be formed thin.
