Abstract:
A heat blow molding apparatus includes a supply section 110, a heating station 112, a transfer section 114 and a blow molding station 116, all of which are disposed linearly in a direction A in which preforms 118 are carried. The supply section 110 supplies the preforms 118 each having a neck portion in their inverted state. The heating station 112 simultaneously heats the inverted preforms 118 while they are being carried parallel to each other. The transfer section 114 transfers the inverted preforms 118 after they have been heated by the heating station. The blow molding station 116 simultaneously blow molds the inverted preforms 118 transferred from the transfer section 114 into containers.
Abstract:
A heat-resistant container molding apparatus and method which are compact and inexpensive and can reliably increase the crystallinity, reduce the residual stress in a container filled with a hot content such as thermally sterilized fruit juice, and prevent a thermal deformation with improved container stability at a raised temperature. The apparatus has a receiving and removing unit for receiving primary moldings obtained by blow-molding preforms and for removing final products, a heat treatment section for heating the primary moldings by bringing the primary moldings into contact with the inner wall of a heat treatment mold while pressurizing the interior of the primary moldings within the heat treatment mold, a final molding section for blow molding intermittent moldings into final products within a final blow mold, and a rotary plate, neck support fixing plate and neck support member for conveying the moldings through the receiving and removing unit, heat treatment section and final molding section.
Abstract:
A rear fork for motorcycles swingably supported at its front end portion from a body frame and supporting at its rear end portion a rear wheel axle, is built-up by interconnecting a plurality of constituent elements. The interconnection between the respective constituent elements is effected in a mutually fitted relationship with an adhesive agent interposed between their fitting surfaces, and if necessary, it is preferable to employ at the connecting portion reinforcing connection means such as rivets.
Abstract:
A pipe frame for a two or three-wheeled vehicle is formed by joining lugs having pipe receptors to other frame components such as seat rails and back stays. The parts are dimensioned so as to provide a slight clearance into which thermosetting resin is inserted. After assembly and finishing of the frame, the resin is set simultaneously with the baking on of the finish.
Abstract:
The present invention provides a method of producing a graded refractive index optical element, the method being capable of easily forming a graded refractive index distribution in a desired portion of a glass substrate without the need for a specific treatment atmosphere, and without using a molten salt. More specifically, the present invention provides a method of producing a graded refractive index optical element comprising applying a paste containing a copper compound, an organic resin and an organic solvent to a glass substrate containing an alkali metal component as a glass component, and then performing heat treatment at a temperature below the softening temperature of the glass substrate.
Abstract:
In an injection stretch blow molding method, at least one injection molded preform is transferred from a preform molding section to a blow molding section by way of a transfer section and the at least one preform is blow molded into at least one container in the blow molding section. In the preform molding section the at least one preform is injection molded in an upright state with an open neck section thereof facing upward. In the transfer section, the at least one upright preform is turned upside-down and transferred to the blow molding section in an inverted state. Then, the blow molding section blow molds at least one container from the at least one inverted preform.

Abstract:
An injection stretch blow molding apparatus and method wherein while the preforms are amply cooled the injection molding cycle time is shortened and furthermore a small number of blow cavities are used. In an injection molding section, N (N.gtoreq.2) preforms are injection molded in an upright state and then released from the injection cavity mold. While the preforms are cooled by the injection core mold, they are carried to a preform ejecting section. After the preforms cool to a temperature at which they can be ejected, the preforms are ejected from the injection core mold. In a transfer station, an array pitch of the simultaneously molded preforms are changed to a blow molding pitch, and then the preforms are transferred to a blow molding station in an inverted state. In the blow molding station, each preform is carried by a carrier member through a heating section into a blow molding section. In the blow molding section, n bottles are simultaneously blow molded from n preforms.

An injection stretch blow molding apparatus and method wherein while the preforms are amply cooled the injection molding cycle time is shortened and furthermore a small number of blow cavities are used and the operation rate of these blow cavities is increased. In an injection molding section, N (N.gtoreq.2) preforms are injection molded and then released from the injection cavity mold at a relatively high mold-release temperature. While the preforms are cooled by the injection core mold, they are carried to a preform ejecting section. After the preforms cool to a temperature at which they can be ejected, the preforms are ejected from the injection core mold. In a transfer station, n (1.ltoreq.n
Abstract:
A suspension in an off-road motor vehicle, includes a vehicle frame, a front wheel, and a trailing arm suspension mechanism by which the front wheel is suspended from the vehicle frame. The trailing arm suspension mechanism comprises two parallel arms having front ends pivotally mounted on a front portion of the vehicle frame and rear ends on which the front wheel is steerably supported, and a joint member connected between the front ends of the arms and including a portion coupled to the vehicle frame.
