  • Patent number: 6976836
    Abstract: In a biaxial stretch blow molding apparatus (10) for wide-mouthed containers, preforms (6) that are in an inverted state are conveyed on a single plane by preform carriers (40) that go around a carrier circuit (30) in the form of a loop, are heated via a heating station (60), and are then transferred via a transfer station (80) to stretch blow molding mold assemblies (72) that go around a circular looped path (71). The molded wide-mouthed containers (1) are taken out of the stretch blow molding mold assemblies (72) along a conveying path on a same plane and collected by a collection station (90). Wide-mouthed containers can be formed continuously and at high speed, which is less wasteful and more economical than the case where wide-mouthed containers that are formed from films.

  • Patent number: 6457967
    Abstract: A biaxially stretching blow molding apparatus perform biaxial stretch-molding for a preform into a predetermined shape by transporting a preform carrier supporting the preform along a transporting path extending across a heating portion and a stretch-molding portion, has first and second reversing means for reversing the preform carrier, and first and second transporting paths forming the transporting path. The first reversing means receives the preform carrier transported in up-side-down position along the second transporting path, reverses the received preform carrier into elected position, and transfers the preform carrier thus reversed to the first transporting path. The second reversing means receives the preform carrier transported in elected position along the first transporting path, reverses the received preform carrier into the up-side-down position, and transfers the preform carrier thus reversed to the second transporting path.

  • Patent number: 6198601
    Abstract: A magnetic head element has one or more rails formed on the surface thereof. Each rail is formed so as to have a tapered angle of 55-85°. To form such a rail, ion milling is conducted; the rail substrate used is allowed to have an inclination angle to 15-60° and is rotated; and there is used, as the ion milling gas, a fluorinated hydrocarbon (e.g., CH2FCF3) gas alone or a mixed gas of said fluorinated hydrocarbon gas and Ar, SF6 or the like. Accordingly, a magnetic head rail shape gives a small variation in flying height between magnetic bead and magnetic disc.

  • Patent number: 5780069
    Abstract: The invention aims at enabling inexpensive manufacture of a preform carrying mechanism of a simple construction for a blow molding apparatus for biaxial stretching of hollow moldings such as PET bottles from preforms. The molding apparatus is provided with a linear carrying line for carrying preforms (P), and the carrying line comprises a beam (81), on which a multiplicity of carrying members (82) are supported, a carrying mechanism (83) and a lifting mechanism (84) for the beam. The carrying members (82) on the beam are repeatedly moved back and forth at a constant feed pitch by means of the mechanisms. A preform grasping/releasing mechanism (85) is actuated in synchronism with the movement so that while the respective carrying members (82) are caused to advance from backward positions, the preforms are delivered to the respective carrying members (82).

  • Patent number: 5687045
    Abstract: A thin film magnetic head comprising a sintered ceramic substrate, an underlayer, a bottom magnetic core film, a magnetic gap film, an insulating film containing coil windings, a top magnetic core film, and a protective layer. The substrate and other films and layers form an air bearing surface. The under layer, the magnetic gap film and the protective layer comprise Al.sub.2 O.sub.3, and the bottom and the top magnetic core films comprise Ni--Fe alloy. This structure gives substantially the same etching rate, when the air bearing surface is polished using a working fluid of pH 6-8, for any of the substrate, the films comprising Al.sub.2 O.sub.3 and metal oxide described above, and the films of Ni--Fe alloy. Thus, steps (pole top recessions) on the air bearing surface can be made as small as 0.015 .mu.m or less. Accordingly, the magnetic head can be held in a stable attitude, thus obtaining good recording characteristics.

  • Patent number: 5668685
    Abstract: A magnetic disc apparatus is disclosed, in which a magneto-resistance effect film converts a magnetic signal into an electrical signal by use of the magneto-resistance effect, a pair of electrodes supplies a signal detection current to the magneto-resistance effect film, and a magnetic domain control layer controls the magnetic domain of the magneto-resistance effect film. The magneto-resistance effect film, the electrodes and the magnetic domain control layer constitute a magnetic head of magneto-resistance effect type. An isolation film is formed in a magneto-sensitive portion of the magneto-resistance effect film between the magneto-resistance effect film and the magnetic domain control layer to break the magnetic coupling between the magneto-resistance effect film and the magnetic domain control layer.

  • Patent number: 5641451
    Abstract: A heat-resistant container forming method includes a step of thermally shrinking a primary blow molded article in a heating furnace before secondary blow molding the primary blow molded article into a final product or container. Into the furnace, hot air which flows along the longitudinal direction of the first blow molded article and whose temperature enough to facilitate crystallization of the primary blow molded article. The primary blow molded article is thermally shrunk by exposing the entire circumferential surface of a barrel of the primary blow article to the hot air and by blowing the hot air longitudinally along the primary blow molded article to heat the barrel circumferentially uniformly. Since hot air touches the barrel as flowing longitudinally thereof, it is possible to increase the heat conductivity of boundary film of the primary blow molded article, without increasing the hot air temperature too high, so that temperature rise of the primary blow molded article is facilitated.

  • Patent number: 5540879
    Abstract: A method of producing a blow-molded PET container suitable for hot-filling includes the steps of injection molding a preform, blow-molding the preform into a primary molded article larger than the desired final container, heating the primary article in a series of oven chambers while its mouth is sealed so that pressure builds within the article to thereby control shrinkage, and blow-molding the shrunken article into the desired container. The two molds are preferably heated, and the mold contact time is as long as allowed by the manufacturing process to help remove internal stresses in the article. An apparatus for carrying out the method includes a first machine having an injection station, a thermal conditioning station, a primary blow-molding station, and an exit station. A second machine includes the oven chambers and a final blow-molding station.

  • Patent number: 5178816
    Abstract: A method of manufacturing a heat resistant plastic vessel including: injection molding a preform; primary stretch blow molding the preform to obtain a primary blow-mold object; heat-shrinking the primary blow-mold object; and secondary stretch blow molding the heat-shrunk object to obtain a secondary blow-mold object as a heat-resistant plastic vessel. In the primary stretch blow molding process, a concavity is formed on a body of the primary blow-mold object. The concavity has a thickness larger than the other body portion. In the heat-shrunk object, the large thickness portion has a lower heat retaining capacity than the other body portion. The heat-shrunk object then undergoes the secondary stretch blow molding process, thereby obtaining the secondary blow-mold object, which has a large thickness portion corresponding to the concavity of the primary blow-mold object to assure high mechanical strength such as buckling strength of the final product.
