  • Radio-frequency module and communication apparatus
    Patent number: 12278425
    Abstract: A radio-frequency module includes a first base made of a first semiconductor material; a second base that is made of a second semiconductor material having a thermal conductivity lower than that of the first semiconductor material and which includes a power amplifier circuit; a third base including a transmission filter circuit; and a module substrate having a main surface on which the first base, the second base, and the third base are arranged. The first base is joined to the main surface via an electrode. The second base is arranged between the module substrate and the first base in a sectional view and is joined to the main surface via an electrode. At least part of the first base is overlapped with at least part of the second base and at least part of the third base in a plan view.

  • Power transmission belt
    Patent number: 5584771
    Abstract: A power transmission belt includes a belt body having a tooth portion and made of a rubber stock of hydrogenated nitrile having a Mooney viscosity at 100.degree. C. of at least 90, whereby the internally generated heat of the belt body during use in a high temperature environment is suppressed. A cashew-modified phenol resin layer is formed at the outermost layer of the cords for bonding with the belt body. The cords are embedded in the longitudinal direction of the belt body.
