  • Publication number: 20240128808
    Abstract: A stator for a rotating electric machine includes a stator core and a stator coil. The stator core is formed of a band-shaped steel sheet that is helically bent and laminated. The stator core has slots each opening at an inner periphery of the stator core and spaced from one another in a circumferential direction. The stator coil is formed of electrical conductor segments that are inserted in the slots of the stator core and connected with one another. The band-shaped steel sheet has slits each of which is formed, at a position corresponding to one of the slots, to be open to the corresponding slot. Each of the electrical conductor segments is substantially U-shaped and has a pair of leg portions respectively inserted in corresponding two of the slots of the stator core; the corresponding two slots are circumferentially apart from each other by two or more slot-pitches.

  • Publication number: 20240089065
    Abstract: Provided is a radio communication device which can prevent interference between SRS and PUCCH when the PUCCH transmission bandwidth fluctuates and suppress degradation of CQI estimation accuracy by the band where no SRS is transmitted. The device includes: an SRS code generation unit (201) which generates an SRS (Sounding Reference Signal) for measuring uplink line data channel quality; an SRS arrangement unit (202) which frequency-multiplexes the SRS on the SR transmission band and arranges it; and an SRS arrangement control unit (208) which controls SRS frequency multiplex so as to be uniform in frequency without modifying the bandwidth of one SRS multiplex unit in accordance with the fluctuation of the reference signal transmission bandwidth according to the SRS arrangement information transmitted from the base station and furthermore controls the transmission interval of the frequency-multiplexed SRS.

  • Publication number: 20230126938
    Abstract: An electric work vehicle includes a mounted body enabling execution of a specific work. The electric work vehicle further includes a main frame, a cab in a front portion of the main frame, an electrical component unit on the main frame in a position lower than a lower surface of the cab, and a power take off (PTO) unit having a work machine drive unit for driving a work machine to execute the specific work by the mounted body, and a mounted motor for supplying rotational power, by electric power of the battery, to the work machine drive unit. In the PTO unit, the mounted motor is in a position lower than the lower surface of the cab and in a lowermost layer region of a space where the electrical component unit is disposed, and the work machine drive unit is disposed in a position rearward from the mounted motor.

  • Patent number: 4192545
    Abstract: A seat-back frame for automotive vehicles comprising a rectangular frame of a rigid material, the frame having two upper and two lower corners, a seat belt connected to one upper corner and a tensile member obliquely extending between an upper and a diagonally lower corner of the frame to reinforce it against rhombic deformation due to external force applied in a lateral direction of the frame due to load applied to the frame, the tensile member being flexed or bowed to some extent in the rearward direction of the seat-back frame to avoid any interference with a cushioning material and cushioning springs when they are pushed backward by an occupant leaning on the seat-back and being flexible enough to straighten under tensile load.

  • Patent number: 4160565
    Abstract: A tongueless type seat belt having a grip which is slidably affixed to the belt to protect the hand of the user when pulling out the belt, to prevent any twisting of the belt, and to be readily locked and unlocked with a tongueless buckle with a one-touch operation. On one end the belt is fixed to a portion of the car, and at the other end it is wound up in a retractor. In the intermediate portion of the belt there is a belt grip for mating with a tongueless buckle. The belt grip is slidable in the lengthwise direction of the belt and encloses the belt. The belt is made so that the front and back surfaces are readily distinguishable from each other.
