Abstract:
The present invention relates to an apparatus for drying a material in a mold cavity, comprising: a microwave device for supplying microwave to the material; and a walking device disposed outside the microwave device and allows the microwave device to be movable along a guide rail disposed inside the mold cavity. The present invention also relates to a method for manufacturing a molded article, comprising: a moisture removing step, in which microwave is applied to the material in the mold cavity to phase the moisture contained in the material into vapor by means of the preceding apparatus, and then the vapor in the mold cavity is removed; and an infusing step, in which a macromolecule material resin is infused into the mold cavity under a negative pressure to manufacture the molded article.
Abstract:
A system for the radiation treatment of substrates, which comprises, in a chamber above the substrate holders for fitting substrates to be treated, at least one radiation source, and wherein the chamber comprises means for maintaining a gas flow in the chamber with at least one gas inlet and at least one gas outlet, characterized in that the at least one gas inlet is disposed in the region of the substrate holders in such a way that gas flowing in through the at least one gas inlet first flows around the substrate holders prior to leaving the chamber again, either directly and/or after flowing around the at least one radiation source, through the gas outlet.
Abstract:
A method of forming a coated medical device is described. A coating may be applied inline to a continuous tubing formed by extrusion, prior to cutting and secondary operations. Thus, inefficient and labor-intensive steps associated with preparing individual tubes for coating may be avoided. The method may include forcing a flowable material through an exit port of an extruder, depositing a coating onto at least a portion of the continuous length of extruded tubing after the tubing is forced through the exit port, cutting the coated tubing to a desired length after depositing the coating, and performing one or more secondary operations on the coated tube at a temperature in the range of from about 15° C. to about 375° C.
Abstract:
A photosensitive material-drying apparatus for drying a photosensitive material after being dipped in a treatment solution to wet the same. Water-absorbing rollers for contact with the same surface of the photosensitive material are provided in the vicinity of a photosensitive material-introducing inlet, and are arranged along a direction of transfer of the photosensitive material. The water-absorbing abilities of the water-absorbing rollers is increased progressively in the direction of transfer of photosensitive material.
Abstract:
A process of cooling a heated polyethylene terephthalate film by applying cooling liquid to both surfaces of the heated film and, after the temperature of the film has decreased sufficiently, removing the cooling liquid from the film, wherein the cooling liquid has a pH value between 6 and 3.
Abstract:
Drying rollers for use in the dryer section of an automatic X-ray or other film developing machine which incorporates a pair of tangentially contacting, thermoplastic, micro-porous rollers which form a nip therebetween to receive the developed film from the wash tank. The rollers serve to dry the film surface by absorbing the moisture into the roller pores by capillary action. The usual dryer section heater continuously dries the rollers as they are rotated in the dryer section when the film travels through the developing apparatus.
Abstract:
A system for the radiation treatment of substrates, which includes at least one radiation source above the substrate holders in a chamber, which holders are to be equipped with substrates that are to be treated, and the chamber has means for maintaining a gas flow in the chamber, having at least one gas inlet and at least one gas outlet, characterized in that the at least one gas inlet is situated in the vicinity of the substrate holders so that gas flowing in by means of the at least one gas inlet first flows around the substrate holders before either exiting the chamber directly via the gas outlet or exiting after flowing around the at least one radiation source.

Abstract:
A process for preparing low moisture content polymer biomaterial composites and expandable polymer biomaterial composites by extrusion through a die plate (18) into a waterbox (16) and pelletizing with cutter blades (14). Polyolefins or condensation polymers are melt blended with a solid or semi-solid biomaterial component (155), such as polysaccharides, including cellulosics and starches, or proteinaceous materials, including polypeptides, and are extruded, pelletized underwater, and processed with accelerated drying to achieve moisture levels as low as one percent (1%) or less.
Abstract:
Disclosed herein are an apparatus and method for manufacturing a balloon catheter in which a non-contact type laser perforator and printer are separately provided above a primary extruder such that inflation apertures can be uniformly perforated through a non-vulcanized lumen tube and simultaneously, tube cutting positions can be printed on the lumen tube at positions uniformly spaced apart from the inflation apertures without stopping a primary extrusion process. Also, a bond preventing agent layer is coated on the lumen tube at balloon inflating portions prior to cutting the tube, to facilitate a secondary extrusion of the tube. With this configuration, continuous and accurate perforation of inflation apertures is possible and automatic tube cutting can be achieved based on the printed tube cutting positions. Also, the present invention can compensate for a time delay due to a bond preventing agent application process and achieve high productivity and minimized loss of material.
