A laminated composite pipe is produced by employing a pre-formed pipe as a core and applying a layer of reinforcing fiber onto the outer surface of the pipe core which is being lowered vertically in the direction of its length through a hopper and a tubular outer mold. Resin supplied to the hopper is drawn into an annular space between the wound pipe and the outer mold and forms a layer on the wound pipe core. A flexible pipe may be used as the core, together with a resin that can be subsequently cured, thereby forming a flexible laminated composite pipe which can be covered with a parting tape, stored in reel form, and given a permanent set after installation by curing the resin. Depending upon the nature of the resin employed and upon the number of resin layers applied to the pipe core, reinforcing, insulating and stiffening properties, or any combination of such properties, may be imparted to the composite pipe. A multi-channel pipe may be formed by the application to one of the composite pipes described above of an additional tape provided with spacer projections, followed by the application of reinforcing fiber and resin.

The invention relates to a yacht. The yacht has a body, and this body comprises at least outer and inner skins formed of a resin material incorporating reinforcement fibers therein, and a formed styrol material as a foamed synthetic resin member filled between the skin layers. Therefore, the body is resistant to compression force, tensile force, and bending force, and well withstands the impact force of waves. By use of these materials, the yacht is inexpensive to construct and is lightweight so that good improvement in speed can be obtained.

A butterfly valve comprises a substantially cylindrical casing (20) having an annular valve seat (A) on its inner peripheral surface, and a valve disk (44) disposed within the casing (20) and rotatable about an axis (35). The valve disk (44) is formed at an outer peripheral edge portion with an annular groove (52) in which an annular valve seal (51) is partially fitted. The valve seal (51) is adapted for pressing contact with the valve seat (A) at a predetermined pressure and anchored in the annular groove (52) by resin (58) pressure-injected into the annular groove (52) through a resin injection channel (53) in communication with the groove. Accordingly, the seal pressure of the valve seal (51) on the valve seat (A) can be set to the predetermined value at all times even if the dimensions of the valve seat (A) and the valve disk (44) and the position of the axis of rotation (35) involve errors.

[Problem]To completely close the space between the hot-water valve 3a and the hot-water valve seat a when ejecting the cold water, without increasing the size of the temperature-sensitive coil spring 5 constituted by the SMA spring. [Solution]In a hot water-water mixing faucet for holding a control valve body 3 in a balanced position between two springs, a bias spring 4 and a temperature-sensitive coil spring 5, and moves an adjusting screw 6a, which supports the bias spring 4, in an axial direction to change setting of the supporting position of the bias spring 4, a rear end side of the bias spring 4 is supported by a supporting member g which is formed separately from the adjusting screw 6a, the supporting member g is slidably inserted in the axial direction into a through-hole 63 provided on the adjusting screw 6a and is connected detachably to the adjusting screw 6a by means of an abutting section t1 provided in an area protruding from the through-hole 63 toward the bias spring 4 side, and a lifting spring 7, which biases the supporting member g to pull the supporting member g back toward the side opposite to the bias spring 4 to the adjusting screw 6a, is provided between an area protruding from the through-hole 63 toward the side opposite to the bias spring 4 and the adjusting screw 6a.
摘要:
An apparatus for exposing the fibrous reinforcements of a fiber reinforced resin body comprises at least one stage in which a portion of the resin body is brought into contact with a heated resin removing liquid while the resin body is vibrated. According to this apparatus subsequent processing of the resin body, e.g., connecting to another similarly treated resin body, can be advantageously conducted by utilizing the exposed fibrous reinforcement.
摘要:
A method and apparatus for manufacturing bent pipes of a composite material composed of resin and filling materials such as reinforcing materials and aggregates by employing a cylindrical molding tool which is deformable between straight-axis form and bent-axis form. Materials are supplied into the molding tool held in horizontally straight condition while the tool is rotated about a horizontal axis, and are molded into a pipe by centrifugal molding. Rotation of the tool is stopped when the pipe molded therein is in uncured state, then the tool is subjected to bending. The resulting bent pipe is removed after it is cured. Before the tool is bent, a bag made of a flexible sheet material is inserted into the pipe and inflated to straighten out the inner periphery of the pipe so as to protect the pipe from any possibility of deformation during bending operation. The molding tool is preferably made of such resilient material as rubber, is incased in a peripherally divisible frame or bellows-type flexible frame which, in turn, is suitably incased in a rotary frame. More preferably, the molding tool has a hollow space provided between its inner and outer walls; by filling liquid in the hollow space it is possible to achieve fine roundness in pipe molding irrespective of dimensional errors with the molding tool or frame.

A hot water-water mixing faucet holds a control valve body in a balanced position between a bias spring and a temperature-sensitive coil spring. An adjusting screw 6a supports the bias spring in an axial direction to change setting of the supporting position of the bias spring, and a rear end side of the bias spring is supported by a supporting member which is formed separately from the adjusting screw. The supporting member is slidably inserted in the axial direction into a through-hole provided on the adjusting screw and is connected detachably to the adjusting screw by an abutting section provided in an area protruding from the through-hole toward the bias spring side. A lifting spring biases the supporting member to pull the supporting member back toward the side opposite to the bias spring to the adjusting screw 6a.
