  • Patent number: 11955919
    Abstract: An electric motor system includes a battery, an inverter, an electric motor, a zero-phase switching arm and a control unit. The inverter converts DC power output from the battery into three-phase AC power and outputs the three-phase AC power to the electric motor. A rotor of the electric motor rotates by the three-phase AC power output from the inverter. A neural point of the electric motor is connected to the zero-phase switching arm. A zero-phase current flowing through respective windings of the electric motor is adjusted by switching of the zero-phase switching arm. By this means, in the electric motor system, torque is generated at the rotor also using the zero-phase current as well as a three-phase AC current flowing through the respective windings.

  • Publication number: 20240087807
    Abstract: A powder magnetic core according to an aspect of the present disclosure is a powder magnetic core in which a magnetic powder is bonded via a binder layer. The powder magnetic core contains 88 volume % or more of magnetic powder, and when a cross-sectional photograph of the powder magnetic core is taken, an area of the cross-sectional photograph having a size of 10000 ?m2 is divided into unit areas, one or more of the unit areas in which the size of a cross-sectional area of a binder accounts for 50% or more of the unit area are extracted as specific unit areas, and the percentage of the number of specific unit areas with respect to the total number of unit areas is equal to or larger than 0.2% but equal to or smaller than 3.0%.

  • Publication number: 20240087781
    Abstract: A powder magnetic core capable of achieving a low loss in a high frequency range is provided. A powder magnetic core according to the present disclosure is a powder magnetic core in which a magnetic powder is bonded via a binder layer. A volume filling percentage of the magnetic powder included in the powder magnetic core is 85 volume % or higher, and a value obtained by dividing a BET specific surface area (m2/g) of the powder magnetic core by a specific surface area (m2/g) calculated using outer dimensions of the powder magnetic core is 5000 or less.

  • Patent number: 5530468
    Abstract: An image recording apparatus comprises a temporary storing magazine for temporarily retaining a recorded photosensitive material sheet. The temporary storing magazine stocks the recorded photosensitive sheet received therein from an image recording section while discharging the recorded photosensitive material sheet into an automatic developing machine. Hence, image recording is executed without interruption and parallel to discharge of the recorded photosensitive material sheet into the developing machine, enhancing the capability of the image recording apparatus.

  • Patent number: 5089845
    Abstract: In a printing apparatus, a supply pallet storing an original and a photosensitive film is located above a printer. The films are carried onto a transparent plate of the printer in this order by a carrier. Then, light from a light source of the printer is directed toward the transparent plate, whereby an image provided on the original film is printed onto the photosensitive film. Thus, the printing apparatus is small in plane size.
