A roller shaft is inserted into a mold including molding members respectively having a first mold surface that defines an outer circumference of a roller portion and second and third mold surfaces that respectively define first and second flat portions of the roller portion, and the mold is then closed. A molding material is injected around the roller shaft to integrally mold the roller portion. The roller portion includes the outer circumference and the first and second flat portions rising from the roller shaft to the outer circumference. The roller shaft includes flange portions at portions corresponding to the first and second flat portions. The flange portions prevent the molding material from leaking outside the first and second flat portions when the roller portion is integrally molded around the roller shaft by injection molding.

The method of manufacturing kinesio brace includes steps of: preparing an elastic body which is tube-shaped to have a first face inside and a second face outside, the elastic body defining an axial direction; inserting an inner mold into the elastic body so that the first face faces to the inner mold; placing the inner mold with the elastic body into an outer mold and closing the outer mold, the outer mold being formed with at least one groove on an inner surface thereof; injecting a plastic material into the groove to shape into a plastic layer which is engaged with the second face of the elastic body; removing the outer mold and the inner mold from the elastic body, reversing the elastic body to make the second face and the plastic layer face inward to provide a kinesio brace.

A safety connector has a needle, and includes a tubular protective sleeve with a distal section, having a movable wall portion arranged in the peripheral wall thereof. The movable wall portion is selectively movable between a retracted position and a protection position. In the retracted position, the movable wall portion is aligned with the peripheral wall of the proximal section of the tubular protective sleeve. In the protection position, the movable wall portion projects into the inner space of the tubular protective sleeve.

Microscale valves for use in, e.g., micropump devices, may be formed of a slitted diaphragm bonded o the interior of a valve tube. A bump in the diaphragm and/or a backward-leakage stopper may increase the breakdown pressure of the valve. A push-rod may be used to pre-load the valve membrane to thereby increase the cracking pressure.

The present invention relates to a system (100) for manufacturing a Field Joint Coating (11), the system comprising: a heating device (102) for heating a quantity of a polymer, an upstream pump (104) for pumping the quantity of heated polymer into a storage compartment (106) of an ejection device (108), the ejection device (108) which is constructed for each time ejecting the heated polymer from its storage compartment, the ejection device comprising: o a barrel (1 10) which defines the storage compartment, the barrel being reinforced and configured for repeated use, o a plunger (1 1), o an actuator (1 14) for driving the plunger through the barrel for emptying the storage compartment, a downstream pump, the downstream pump being constructed for increasing the operating pressure of the ejected polymer, —a mould (200) configured to be positioned at a field joint (13) around a pipeline.
摘要:
An electrochemical cell (10), in particular a fuel cell and/or an electrolytic cell and/or a metal-air cell, having at least one functional layer system (12), which is distinguished by the fact that at least one tubular support body (14) is formed, in which at least one tunnel-like structure (16) is formed, which adjoins the at least one functional layer system (12). A method for producing an electrochemical cell (10).
摘要:
A process of producing a hollow item by injection-moulding thermoplastic material, which has a rigid external shell and at least one soft internal portion, which uses a mould comprising a matrix, a first semi-mould including a first cavity and a second semi-mould including a second cavity counter-shaped to the matrix to reproduce a respective semi-shell of said rigid external shell. The process includes the phases of positioning at least one insert made of a soft material, constituting the soft internal portion, on the matrix; covering the insert with a connecting layer; hermetically sealing the first and second semi-moulds onto the matrix along the edges of the cavities; injecting into the space between the cavities and the connecting layer a thermoplastic material that forms the rigid external shell to create a permanent connection of the soft insert to the shell. The connecting layer substantially retains the characteristics of the soft insert.

A syringe (20) is disclosed including a needle (22) and a barrel (24). The needle can have an outside surface (32), a delivery outlet (34) at one end, a base (36) at the other end, and an internal passage (38) extending from the base to the delivery outlet. The barrel can have a generally cylindrical interior surface portion (40) defining a lumen. The barrel also can have a front passage (44) molded around and in fluid-sealing contact with the outside surface of the needle. A method of making such a syringe is also disclosed. A mold (80) for making the barrel defines a front opening of the barrel to be molded around and in fluid-sealing contact with the outside surface of the needle. The needle is positioned within the mold cavity, with its base abutting the core. The barrel is molded against the needle to join the barrel and the needle.

A blow-by heater includes a metal pipe for flowing a blow-by gas therethrough. The metal pipe includes a flat portion on one side along an axis direction and a curved portion on a side opposite to the flat portion and is formed of a metal plate with a joining portion abutting against each other at edges of the metal plate at the curved portion. The blow-by gas heater further includes a resin molded over the metal pipe, and a heating source provided inside resin and directly contacting the flat portion.
