  • Patent number: 11386878
    Abstract: A broadband ultrathin sound absorption or sound insulation structure controlling an acoustic wave propagation path has at least one sound absorption unit or one sound insulation unit; and each sound absorption unit or sound insulation unit has at least one acoustic wave focused section and at least one acoustic wave absorption section. The acoustic wave focused section is formed by an acoustic wave focused cavity filled with acoustic material. The acoustic wave focused section controls the acoustic wave propagation path through the change of a section of the cavity and the change of material equivalent parameters in the cavity, so that the acoustic waves are focused and propagate along the curve. The acoustic wave absorption section realizes efficient broadband sound absorption through the filled sound absorption materials and the arranged periodic local oscillators along an ultralong path of acoustic wave absorption labyrinth passage.

The plate is made by brazing hard particles into a matrix of brazing material attached to a steel plate. Nickel-Silver brazing material is used to form the matrix on the steel plate, and tungsten carbide particles of 8-10 mesh are secured within the matrix, with the hard particles of tungsten carbide partially exposed, presenting a roughened surface with angular pieces of tungsten carbide to the drilling attack.

    Abstract: Systems and methods consistent with the present invention provide a thermoplastic resin-laminated structure having an exterior layer, a base layer, and a binding layer that is placed between the exterior layer and the base layer. The exterior, base and binding layers include at least one material selected from a group consisting of electric resistance-heat generating materials and heat-conductive materials, and has at least one connection terminal at a certain region for supplying at least one of electricity or heat. The resin-laminated structure has excellent properties such as adhesive strength between a base layer and an exterior layer, and recycling utility as well as surface quality in feeling, thermal durability, acoustic absorptivity, heat-shielding property, and impulse-durability.

  • Patent number: 6475635
    Abstract: A copper alloy sliding material which can bring about superior resistance to fatigue as well as good anti-seizure property without containing any Pb. The copper alloy sliding material is made to have the structure in which both of the hard copper alloy phase and the soft copper alloy phase coexist in a mixture state. On the surface of the sliding material, the soft copper alloy phase comes to have a shape more concave than that of the hard copper alloy phase when receiving a load or when being in a sliding wear relation, in which concave portions is retained lubricant with the result that the anti-seizure property is enhanced. Further, since the soft phase and the hard phase are made of the same copper alloy, the wettability thereof becomes good, and Ni and etc. contained in the hard copper alloy phase are diffused into the soft copper alloy phase, so that the hardness of the boundary portion defined between the phases come to be gradually varied.

  • Patent number: 6372362
    Abstract: A method for forming a composite vapor-deposited film one side of which suitable for vapor-deposition on a phosphor surface of a CRT, such as a color television picture tube, has high light reflectivity, and the other side of which has a property to absorb radiant heat, and a composite vapor-deposition material suitable for vacuum deposition are disclosed. The composite vapor-deposition material has a high vapor-pressure metal envelope and a low vapor-pressure metal in the core region of the envelope. Low vapor-pressure metal powder should preferably be dispersed and held by high vapor-pressure metal powder in the core region. Vacuum deposition using this composite vapor-deposition material yields a composite deposited film having a composition comprising almost 100% of the high vapor-pressure metal formed in the initial stage of evaporation, and a composition comprising 100% of the low vapor-pressure metal formed in the final stage of evaporation.
