  • Four-wheel drive hybrid vehicle
    Patent number: 6569055
    Abstract: A hybrid vehicle includes a first motor generator (1) and an engine (3) connected to first drive wheels (7) via a transmission (5), a second motor generator connected to a second drive wheel (17), a battery (8) electrically connected to the first and second motor generators (7,17), a sensor (25) which detects a running state of the vehicle, a sensor which detects a charge state of the battery (8), and a controller (10,11,12). The controller (10,11,12) controls a drive force of the engine (3) and the first motor generator (1) according to the running state of the vehicle and the charge state of the battery (8), and drives the second motor generator (2) by the battery (8) or the power generated by the first motor generator (1).

  • Optical recording and reproducing apparatus for verifying correct writing of information signal
    Patent number: 4935914
    Abstract: An optical recording and reproducing apparatus includes a controlling circuit for controlling a light intensity of a laser beam emitted by a laser diode. The controlling circuit sets the light intensity in a verifying mode at a level lower than those in data read and write modes. The verifying mode is a mode for verifying whether or not the recording or reproducing apparatus can operate correctly. The apparatus also comprises a verifying circuit for comparing the reproduced information signal obtained in the verifying mode with a reference information signal which corresponds to the information signal written into the optical disc.
