There is provided a method of manufacturing an optical module comprises a component fixing step in which an optical waveguide and at least one optical device are detachably held by a fixing member capable of holding an uncured light curable resin in a required position, and a core forming step in which light of a wavelength for curing the light curable resin is emitted from the leading end of the optical waveguide to the light curable resin uncured and thus the light curable resin is cured to form a shaftlike core. According thereto, the optical waveguide and the optical device are connected by the core.

A flange is provided at the opening metal of a pressure container, and it extends toward the periphery of the container body at the bonding part thereof at which it bonds to the container body. The liner of the pressure container has a self-sealing part at which it abuts the flange to be sealed up together. On the outer peripheral side of the self-sealing part, a ring-shaped constraint member is provided in the outer periphery of the liner, and the constraint member is to restrict the diameter expansion of the liner to be caused by the expansion of the container body. The liner has an easily-displaceable part that is readily elongable and deformable, at the outer periphery thereof in the radial direction of the self-sealing part.

An intake air duct serves as a passage for supplying air to an engine, and includes a first intake air passage, a second intake air passage, an opening-and-closing valve, an interlocking member and a coiled spring. The opening-and-closing valve is disposed swingably in the second intake air passage so as to open and close the second intake air passage. The interlocking member is disposed outside the first intake air passage or the second intake air passage, and swings by interlocking with the swinging of the opening-and-closing valve. The coiled spring is disposed swingably outside the first intake air passage or the second intake air passage, and has a swinging end, which is brought into contact with a surface of the interlocking member. The swinging end slides on a surface of the interlocking member as the swinging of the interlocking member. The second intake air passage is opened by the opening-and-closing valve when a first urging force, which acts onto the coiled spring while the interlocking member swings so as to interlock with the opening-and-closing valve being swung in an opening direction by a negative pressure exerted in the second intake air passage, is larger than a second urging force, which is exerted by a spring elasticity of the coiled spring. The second intake air passage is closed when the first urging force is smaller than the second urging force.

Intake air duct

An intake duct capable of reducing intake noise when an engine runs at a low speed and supplying a sufficiently large amount of air when the engine runs at a high speed without using any electron control circuit or electromagnetic valve, which is produced at low costs. The intake duct includes valve adjusting means which restrains the movement of the valve member when the valve member brings a second intake passage from the closed state to the open state, and facilitates the movement of the valve member when the valve member brings the second intake passage from the open state to the closed state. When the second intake passage is brought to the open state from the closed state, the restraining force of the valve adjusting means is great to restrain the movement of the valve member, and when the second intake passage is brought to the closed state from the open state, the valve member readily pivots to open the second intake passage. Thus, the valve member is free from the half-closed state, and consequently, the generation of low-frequency booming noise can be prevented.
