Abstract: In an injection molding machine, a hydraulic actuator and a hydraulic pump are arranged close to each other to make a hydraulic pipe as short as possible so as to improve maintenanceability and improve reliability of a hydraulic drive part. The injection molding machine has one movable part configured to be movable with respect to a body frame. The hydraulic actuator and the hydraulic pump unit are fixed to the movable part. The hydraulic pump unit supplies a generated fluid pressure to the hydraulic actuator. The hydraulic pump unit and the hydraulic actuator are connected by a hydraulic passage provided to the movable part. The hydraulic actuator, the hydraulic pump unit and the hydraulic passage are moved with a movement of the movable part.

Abstract: A plasma display apparatus (10) is provided with: a control device 100; a PDP 900 including a display panel device 200 and a driving device 400; and a functional device 500. In operation of the PDP 900, an X driving device 420 and a Y driving device 430 of the driving device 400 are drive-controlled by the control device 100, and sustain pulse voltages are applied to sustain electrodes 213 of the display panel device 200. This generates unnecessary radiant electromagnetic wave near the display panel device 200 and the driving device 400. A coil 610 of a power regenerating apparatus 600 is provided such that the core direction of an air core portion 611b is perpendicular to the radiant direction of the unnecessary radiant electromagnetic wave, and the coil converts the unnecessary radiant electromagnetic wave to an AC voltage. The AC voltage is converted to a DC voltage by a rectifying device 620 and it is regenerated as DC power for the functional device 500 through a power supply line.

Abstract: A rear axle apparatus for a tractor having differential gear shafts driven by power transmitted from a transmission, rear axles connected to the differential gear shafts through planetary reduction mechanisms, and brakes for braking the differential gear shafts through brake disks engaged with the differential gear shafts. The apparatus includes a rear axle case connectable to a case of the transmission and having an inner peripheral surface. Each planetary reduction mechanism includes a ring gear mounted on the inner peripheral surface of the rear axle case. A brake support receives one of the brake disks. The brake support is mounted on the inner peripheral surface of the rear axle case, and arranged parallel to the ring gear substantially along the rear axles. A rotation stopper limits rotation of the brake support and the ring gear relative to the rear axle case.
