An object of the present invention is to create, from a titanium alloy and an FRP prepreg, a composite of a titanium alloy and an FRP material that is suitable for bolt fastening. The composite can bring out excellent characteristics in CFRP members in mobile electronic-electric devices, mobile equipment, medical instruments, marine devices and the like. It has been found that titanium alloy having a special constant surface shape adheres strongly with an epoxy adhesive. In a composite obtained using this technique to integrate a titanium alloy member as a cover material and a CFRP material, the metal alloy portion deforms and disperses locally strong forces so that the CFRP material is not damaged, even when the composite is assembled to another metal member through bolt-fastening. As a result, the composite is expected to be effective for applications in mobile equipment or mobile device casings, where lightweightness, corrosion resistance, toughness and ease of assembly are required.

Titanium alloy composite and bonding method thereof

The invention provides the advantages of a metallic housing and those of a synthetic resin structure for electronic devices, home electrical devices, etc., achieves high productivity and mass productivity, and enables a desired configuration and structure to be designed freely. As a pretreatment, a shaped aluminum alloy material is dipped in an aqueous solution of at least one selected from the group consisting of ammonia, hydrazine, and a water-soluble amine compound. A thermoplastic resin composition containing polyphenylene sulfide as a component is integrally bonded to the surface of the treated shaped aluminum alloy material by injection molding or other method. The molded article is a product made of the shaped aluminum alloy material and the thermoplastic resin composition containing PPS. Thus, the characteristic features of metal can be utilized in terms of mechanical strength and external appearance design. Moreover, a complicated configuration and structure can be formed inside the housing.

The present invention is useful for achieving a reduction in weight and for attaining increased strength in not only electronic devices and domestic electric devices but also various parts and structures. As a pretreatment, a rib () is dipped in an aqueous solution of ammonia, hydrazine, a hydrazine derivative, or a water-soluble amine compound. A metal frame () is inserted into an injection mold for forming ribs () by injection molding. A thermoplastic resin composition is injected to the surface of the metal frame () by injection molding to form ribs (). In the housing of a casing cover () thus formed, the metal frame () and the ribs () made of the thermoplastic resin composition are integrally bonded together. Thus, the housing improves strength and external appearance. Moreover, a complicated configuration and structure can be formed in the housing.

An optical ring system having: a wavelength demultiplexer to which wavelength-multiplexed optical signal to be sent through an optical fiber from a previous node of multiple nodes is input and in which optical signal with each wavelength assigned to itself is demultiplexed; an optical ring device which is disposed in a predetermined node of the multiple nodes to the each wavelength assigned and which is composed of a failure existence judging part which terminates an overhead of each optical signal with a wavelength demultiplexed by the wavelength demultiplexer and judges whether a failure occurs in regard to a wavelength in a previous section through which optical signal with the assigned wavelength is sent, and a switching part which, when the failure existence judging means determines the occurrence of failure, selects a path that allows optical signal with the wavelength to be transmitted to the previous node while avoiding the previous section incurring the failure; and a wavelength multiplexer which multiplexes optical signal to be output from the optical ring part and then outputs it to an optical fiber connected to a next node.

According to a connection switching method of a switch for selectively setting a connection path between a plurality of input lines and a plurality of output lines, the types of faults which may occur on the input lines are defined. Connection destination information indicating connection states of the switch are stored in accordance with the types of faults. The type of fault is specified on the basis of the defined types of faults when a fault occurs on an input line. Connection destination information corresponding to the specified type of fault is read out. The connection state of the switch is switched on the basis of the readout connection destination information. A connection switching apparatus is also disclosed.
