  • Patent number: 11987243
    Abstract: A control mode of speed control includes a first control mode in which an actual speed is caused to follow a target speed through active use of a brake and a second control mode in which the actual speed is caused to follow the target speed while use of the brake is suppressed. An autonomous driving system changes a threshold value to a value larger than a value in the first control mode when the control mode is switched from the first control mode to the second control mode, and changes the threshold value to a value smaller than a value in the second control mode when the control mode is switched from the second control mode to the first control mode.

  • Publication number: 20240113810
    Abstract: A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts that encode transport data; a mapping part that performs such a mapping that encoded data sequentially formed by the encoding parts are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

  • Patent number: 11404265
    Abstract: A film deposition method is provided. In the method, chlorine gas is activated in a plasma generator, and an adsorption inhibitor group is formed by adsorbing the activated chlorine gas on a surface of a substrate in a processing chamber. A source gas containing chlorine and one of silicon and a metal is adsorbed on a region without the adsorption inhibitor group of the surface of the substrate, and a nitride film is deposited by supplying a nitriding gas to the surface of the substrate and causing the nitriding gas to react with the source gas. The substrate on which the nitride film is deposited is carried out of the processing chamber, and an inside of the plasma generator is purged with activated oxygen gas.

    Abstract: A developing device includes a developer bearer, a developer regulator, a developer supply passage, and a stopper. The developer bearer includes a magnetic field generator and is configured to bear a developer containing toner and magnetic carriers and conveys the developer to a developing area by rotation. A stopper prevents the developer blocked by the developer regulator from moving to a surface of the developer bearer, while securing a supply path for passing the developer in the developer supply passage to the developer bearer between the stopper and an upper end of a side wall of the developer supply passage that is opposite to the developing bearer. A width of the supply path in a direction perpendicular to a direction of a rotation axis of the developer bearer is in a range of 7%-10% of a circumference of an outer diameter of the developing bearer.
