  • Publication number: 20220350572
    Abstract: A random number generation unit and a computing system using the same, the unit including a magnetic tunnel junction element and being capable of developing the characteristics required for the execution of probabilistic computing and operating at a higher speed. A magnetic tunnel junction element includes a fixed layer having a ferromagnet and having a magnetization direction fixed substantially, a free layer having a ferromagnet and having a magnetization direction varying with a first time constant, and a barrier layer disposed between the layers configured with an insulator. The magnetic tunnel junction element has a shift magnetic field of an absolute value of 20 millitesla or smaller. The fixed layer has a plurality of ferromagnetic and non-magnetic coupling layers laminated one upon another, and ferromagnetic layers adjacent to each other among the respective ferromagnetic layers are coupled in terms of magnetization by the non-magnetic coupling layers in an antiparallel manner.

  • Patent number: 7730997
    Abstract: The present invention provides an air intake noise reducing device, an internal combustion engine fitted with the air intake noise reducing device and a structure for fitting the air intake noise reducing device to the internal combustion engine. The air intake noise reducing device comprises a gasket (2) comprising a ring member (2a) held by connecting surfaces of an air intake passage (100) and protrusion holding portions (2b) extending from the ring member (2a) toward a center of the air intake passage (100); and a net member (3) comprising a net (3a) for rectifying intake air and connecting protrusions (3b) extending outward from the net (3). The connecting protrusions (3b) are held in the protruding holding portions (2b) such that the ring member (3) is firmly secured to the gasket (3). The air intake noise reducing device constituted by in the above-mentioned manner can reduce assembly man-hours without deteriorating a sealing property of the air passage.

  • Patent number: 7435371
    Abstract: The present invention provides a method for manufacturing rubber parts monolithically combined with the substrate capable of molding, vulcanizing and adhering at a relatively low temperature. The method by the present invention for manufacturing rubber parts monolithically combined with a completed substrate 111, is a method to form rubber parts at precise positions on a substrate 101 comprising: a placing step to place the substrate 101 in a die assembly K for molding rubber parts; a molding step to mold the rubber parts by casting unvulcanized rubber material 102 into the die assembly K in which the substrate 101 is placed; a releasing step to take unvulcanized rubber parts 104 monolithically combined with the substrate 101 out of the die assembly and a vulcanizing step to vulcanize the rubber parts monolithically combined with the substrate.
