  • Publication number: 20250015720
    Abstract: A control apparatus for a DC-to-DC converter includes a switching controller working to selectively perform a first control task and a second control task. The first control task is to control on-off operations of switching devices of the DC-to-DC converter not to have at least one of an all-on period and an all-off period. The all-on period being a period of time in which all the switching devices are turned on. The all-off period is a period of time in which all the switching devices are turned off. The second control task is to control the on-off operations of the switching devices to have both the all-on period and the all-off period. The switching controller works to change the first control task to the second control task before a current mode is switched from a continuous current mode to a discontinuous current mode.

  • Patent number: 11596924
    Abstract: Superabsorbent particles have a median size of from about 50 to about 2,000 micrometers and contain a porous network that includes a plurality of nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers, wherein the superabsorbent particles exhibit a Vortex Time of about 80 seconds or less and a free swell gel bed permeability (GBP) of 5 darcys or more, of 10 darcys or more, of 20 darcys or more, of 30 darcys or more, of 60 darcys or more, or of 90 darcys or more. A method for forming such superabsorbent particles includes forming a composition that contains a superabsorbent polymer and a solvent system; contacting the composition with a non-solvent system to initiate formation of the porous network through phase inversion; removing non-solvent from the composition; and surface crosslinking the superabsorbent particles.

  • Patent number: 11092197
    Abstract: A rolling bearing device includes: a bearing portion; an oil supply unit that has a pump; a first detection portion that detects operation of the pump; a second detection portion that detects the rotational state of the bearing portion; and a processing portion that generates determination information related to the lubrication state of the bearing portion on the basis of a detection signal from the first detection portion and a detection signal from the second detection portion. The processing portion outputs, to the pump, an instruction signal for oil supply when it is determined that operation of the pump is appropriate and that the rotational state of the bearing portion is not appropriate, and re-determines, after the lapse of a predetermined time, whether or not the rotational state of the bearing portion is appropriate.

  • Patent number: 10801548
    Abstract: A pump includes a piezoelectric element that deforms when a drive voltage is applied to it, and a reservoir that has a capacity to store lubricating oil and that is at least partially deformed elastically to change in the capacity when the piezoelectric element deforms. The pump discharges the lubricating oil when the reservoir decreases in the capacity. A drive circuit unit is switchable between an application state where the drive circuit unit applies the drive voltage to the piezoelectric element, and a release state where the drive circuit unit releases the drive voltage applied to the piezoelectric element. A controller controllably switches the drive circuit unit between the application state and the release state. An electric power storage unit stores electric power that is output from the piezoelectric element when the drive voltage applied to the piezoelectric element is released.

  • Patent number: 10788074
    Abstract: A rolling bearing device includes a bearing portion and a power generation portion. The power generation portion has a plurality of projecting portions provided on an outer ring spacer, a pair of core members provided on an inner ring spacer, a magnet, and a coil. The power generation portion generates an induced current in the coil as the projecting portions pass in the vicinity of first side end portions of the core members during rotation. There are two different loop paths along which magnetism generated by the magnet flows: a first loop path formed when the projecting portions are close to the first side end portions of the core members; and a second loop path formed when the projecting portions and the first side end portions of the core members are away from each other.
