  • Publication number: 20240127982
    Abstract: An information processing apparatus includes a converting portion having a plurality of electrical conductors to be arranged in mutual separation and a medium arranged so as to mutually connect the plurality of electrical conductors, wherein the converting portion is the information processing apparatus to convert an input signal to an output signal. The medium includes the electrolyte and is configured to be capable of controlling an electrical conductivity of an electrically conductive path mutually electrically connecting the plurality of electrical conductors, and the medium is selected such that the electrical conductivity of the electrically conductive path changes over time with the input signal not being present.

  • Patent number: 6220758
    Abstract: A roller supporting device which comprises a pair of supporting arms, a supporting shaft attached between the pair of supporting arms in a non-rotatable manner, and a roller having an inner hole in the central part thereof, the roller being disposed between the pair of supporting arms and being supported in a rotatable manner by the supporting shaft inserted through the inner hole, the roller being arranged to rotate along with the relative movement with a mating member by making the roller contact with the mating member, wherein a cut out portion, which extends in the axial direction on the outer circumferential surface of the supporting shaft, is formed at an appropriate portion except the portion on which the inner circumferential surface of the inner hole of the roller is pressed due to the load applied to the roller from the mating member, thereby defining an oil passage which extends in the axial direction between the supporting shaft and the inner circumferential surface of the inner hole of the roller

  • Patent number: 6176621
    Abstract: A rotary slide bearing part of a rotary slide slit bearing for supporting a rotary shaft thereon in a rotatable manner, has a first bearing surface portion adapted to be arranged adjacent to a second bearing surface portion of another rotary slide bearing part of the rotary slide slit bearing, a load from the shaft to be borne by the first bearing surface portion is larger than a load from the shaft to be borne by the second bearing surface portion, the first bearing surface portion includes a fluidal pressure generating surface facing close to the shaft to generate a fluidal pressure between the fluidal pressure generating surface and the shaft, a main groove arranged at an circumferential end of the first bearing surface portion adjacent to the second bearing surface portion, and a sub-groove extending from the main groove in a circumferential direction of the first bearing surface portion, and an axial width of the sub-groove is smaller than that of the main groove.

  • Patent number: 5727885
    Abstract: A positioning lug 13 is formed which curvedly expands outwardly along the circumference of a half-circular bearing body 11 from the external surface of the bearing body. The positioning lug 13 is provided so that both transition sections thereof are integrated at a circumferential ends 12 with the bearing body 11. Unlike a conventional sliding bearing half shell provided with a tongue-like positioning lug protruding from a proximal end line 14, with transition sections separated from the bearing body, the sliding bearing half shell according to the present invention does not undergo the failure of its positioning lug due to the fatigue of the proximal end line 14 caused by cyclic bending stress.
