  • Patent number: 11156170
    Abstract: A control device for an internal combustion engine includes an internal combustion engine and a valve opening-closing timing control device. The valve opening-closing timing control device has a phase adjustment mechanism for setting a relative rotation phase of a driving-side rotator and a driven-side rotator. The phase adjustment mechanism overlaps a timing of opening an intake valve with a timing of opening an exhaust valve, by setting, in a predetermined period, the relative rotation phase such that the exhaust valve closes after a top dead center position has been reached, and a bypass passage is provided that connects an exhaust passage of one cylinder that is in an exhaust process to the exhaust passage of another cylinder that is in an intake process at the same time as the exhaust process.

  • Patent number: 10818617
    Abstract: Examples of a package for a flange mount device are described. In one example, the package includes a thermally conductive base, a base substrate, and a lid having a cavity. The base substrate includes a through hole and radio frequency (RF) input, RF output, and bias traces that extend to a perimeter of the through hole. The lid includes a cavity and RF input coupling, RF output coupling, and bias coupling traces. A device can be secured to the thermally conductive base, and the lid can be secured to the thermally conductive base, with the base substrate secured between the lid and the thermally conductive base, coupling the traces of the base substrate to the traces of the lid. Other components, such as biasing, blocking, and bypassing components can be easily integrated into the package. Impedance matching and electromagnetic shielding components can also be easily integrated into the package.

  • Patent number: 10175402
    Abstract: A phase difference film layered body is obtained by stretching a film before stretching, the film before stretching including: a P1 layer formed of a resin p1 containing polyphenylene ether having a positive intrinsic birefringence value and a polystyrene-based polymer having a negative intrinsic birefringence value and having a syndiotactic structure; and a P2 layer disposed in contact with the P1 layer and formed of a resin p2 containing an acrylic resin or an alicyclic structure-containing polymer. In the resin p1, the weight ratio of (the content of the polyphenylene ether)/(the content of the polystyrene-based polymer) is 35/65 to 45/55. A method for producing the phase difference film layered body and a method for producing a phase difference film using the phase difference film layered body are also provided.
