  • Patent number: 10087759
    Abstract: An electric compressor includes an inverter housing accommodating an inverter, a compressor housing accommodating a compression mechanism and an electric motor, and a seal member having an annular shape and interposed between an end surface of a peripheral wall of the compressor housing and an end surface of the inverter housing. The compressor housing has the peripheral wall in which the inverter is disposed. The seal member is retained to the inverter housing by a retaining structure which is disposed inside the peripheral wall of the compressor housing. The retaining structure includes a first projection and a second projection. The first projection is formed on the seal member and projects radially inward. The second projection is formed on the inverter housing. The first projection is located between the second projection and the end surface of the inverter housing so as to restrict movement of the seal member in a direction.

  • Patent number: 10065643
    Abstract: In a vehicle travel control apparatus configured to determine a target acceleration of an own vehicle based on an inter-vehicle distance to a predicted cutting-in vehicle predicted to cut in between the own vehicle and a following target vehicle as well as an inter-vehicle distance to the following target vehicle, it is necessary to notify a driver of the presence of the predicted cutting-in vehicle at an appropriate timing. A cutting-in probability, which is a probability that the predicted cutting-in vehicle carries out the cutting in, is acquired, and information on the predicted cutting-in vehicle is notified to the driver from a time point when a state where the cutting-in probability is higher than a start probability threshold has continued for a predetermined period to a time point when a state where the cutting-in probability is lower than an end probability threshold has continued for a predetermined period.

  • Publication number: 20180199506
    Abstract: “A self-propelled grass mower and a self-propelled wheeled apparatus that can perform precise guidance control by reliably detecting a guidance signal with a guidewire are provided. The self-propelled grass mower includes wheel motors for driving wheels, a cutting blade motor for driving a cutting blade, a rechargeable battery for supplying electrical power to these motors, and a guidewire sensor for detecting a magnetic field generated by a guidewire formed into a loop. In the self-propelled grass mower that detects whether is inside or outside of a region enclosed by the guidewire and runs autonomously in a grass cutting region, only the supply voltage for the cutting blade motor is reduced when a magnetic field is detected by the guidewire sensor. Driving of the cutting blade motor is restarted after detection of the magnetic field has completed. Thereby, the impact of noise due to the cutting blade motor is eliminated.
