  • Patent number: 10954962
    Abstract: An object is to provide a vacuum pump that enables, without being affected by a flow rate of gas to be discharged, concentrated and efficient heating of only a stator component of an exhaust side gas channel that needs to be heated in order to prevent deposition of products and that also enables prevention of deposition of products in the exhaust side gas channel as a result of the heating, and improvement of pump emission performance. The vacuum pump has a rotor rotatably arranged on a pump base and a gas channel through which gas sucked by rotation of the gas is guided to an outlet port, and further includes heat insulating means for thermally insulating a stator component, which forms an exhaust side gas channel in the gas channel, from other components and heating means for heating the thermally insulated stator component.

  • Publication number: 20210078586
    Abstract: Provided is a vehicle control device capable of accurately estimating a self-vehicle location with a yaw angle error occurring when a vehicle starts to travel due to an initial phase shift between pulsed waveforms of left and right wheels when the vehicle starts to travel suppressed. The vehicle control device further estimates a direction of wheel rotation while the vehicle is at a stop. A yaw angle deviation when the vehicle starts to travel is estimated and corrected on the basis of a weighted average of discrete yaw angle values obtained immediately after the vehicle starts to travel from wheel speed sensors installed on left and right non-steered wheels of the vehicle. A yaw angle while the vehicle is at a stop and a yaw angle when the vehicle starts to travel are also estimated, and the direction of wheel rotation while the vehicle is at a stop is also estimated from a difference between the yaw angles. The yaw angle and coordinates are corrected on the basis of the estimation result.
