摘要:
In the process where a shaped product of expanded polystyrene is continuously produced by passing preliminarily expanded beads of polystyrene interposed inside a carrying means comprising a circulating steam-permeable single belt or a set of belts of the same nature through a pressurized steam chamber provided with pressure-sealing means at the inlet and the outlet thereof, thereby closely integrating the beads into a sheet through softening and expansion of the beads by steam heating, then cooling the resulting shaped product, and separating the shaped product from the carrying belt or belts, while withdrawing the shaped product to a successive step and returning the carrying belt or belts to the inlet side of the pressurized steam chamber, at least one of the surfaces of the carrying belt(s) is wetted with water before supplying the preliminarily expanded beads onto the belt(s) on the inlet side of the pressurized steam chamber, and thereafter the preliminarily expanded beads are supplied in excess onto the wetted surface(s) of the belt(s), the beads free from the adhering action due to the surface tension of water on the surface(s) of the belt(s) are removed from the belt(s), and the remaining beads attached to the wet belt(s) are fed into the pressurized steam chamber, while being interposed between the belts.

An object of the present invention is to provide a process according to which 5-ene-3-one or 3,6-dione derivatives of sterols can be synthesized with a better yield, as well as a process for production of lipid metabolism improvers, foods, drinks, and animal feeds containing the 5-ene-3-one or 3,6-dione derivatives of sterols.The process for production of 5-ene-3-one or 3,6-dione derivatives of sterols of the present invention involves preparing a culturing solution containing an Arthrobacter bacterium, which is a microorganism exhibiting a cholesterol oxidase activity, and then, adding to the culturing solution an equivalent amount of hexane so as to prepare a bilayer solution consisting of an aqueous layer and a hydrocarbon-based solvent layer. Thereafter, sterol, or a derivative thereof, is made as a substrate contained therein, a reaction performed with cholesterol oxidase at 30° C. for 2 days, and, ethanol then added to separate a hydrocarbon-based solvent layer. Thereafter, the layer is dried to a state of dryness by means of a vacuum dryer so as to obtain 5-ene-3-one or 3,6-dione derivatives.

摘要:
A paper feeding apparatus is provided for use in a web threading apparatus of a rotary press for threading a web along a web threading path by drawing a leading end of the web using a web threading member movably provided on an outside portion of the web threading path and along the web threading path. The paper feeding apparatus includes a pair of an upstream roller and a downstream roller extending substantially parallel to a width direction of the web in the web threading path, and a driving mechanism for driving the upstream and downstream rollers in a feeding direction of the web and for ensuring that a peripheral speed of the downstream roller is at least equal to a moving speed of the web threading member. The upstream and downstream rollers are offset on an upstream side and a downstream side in a direction of the web threading path so that the web is not nipped by both the upstream roller and the downstream roller. A peripheral surface of one of the upstream and downstream rollers contacts a first side surface of the web and a peripheral surface of the other of the upstream and downstream rollers contacts a second side surface of the web, in a manner such that slipping between the rollers and the web is increased in response to a lowering of a tension on the web and such that slipping between the rollers and the web is decreased in response to an increase of the tension on the web. In addition, the upstream roller is displaceable in accordance with a variation of the tension on the web so as to constantly apply a force against the tension.

An improved semiconductor device is disclosed which is free from current leakage due to pin-holes or other gaps. Also an improved method for provessing a semiconductor device is shown. According to the invention, gaps produced in fabricating process of the semiconductor layer are filled with insulator in advance of deposition of electrodes. By virtue of this configuration, short current paths do not result even if transparent electrode is provided on the semiconductor layer.

A solar cell comprises a plurality of series connected photoelectric conversion structures formed on a substrate. The conversion structure consists of a first semiconductor film on a P-type, an intrinsic semiconductor film formed on the first semiconductor film such that one end thereof extends beyond an end of the first semiconductor film and a second semiconductor film of a second, opposite conductivity type formed on the intrinsic semiconductor film such that one end thereof extends beyond the extended end of the intrinsic semiconductor film and makes direct electrical contact with an end of the first semiconductor film of the adjacent structure.

An improved semiconductor processing is desclosed. In the manufacturing process, just formed semiconductor layer undergoes photo annealing and latent dangling bonds are let appear on the surface and gaps, then neutralizer is introduced to the ambience of the semiconductor. The semiconductor thus formed demonstrates SEL effect in place of Staebler-Wronski effect.
