  • Patent number: 11236817
    Abstract: A gear shift operation device for a vehicle to which a multiple-stage automatic transmission is mounted, is provided. By a control lever being manually operated in a range switchable mode, a range position is switched at least between a D-range where automatic transmission is performed and an R-range, and by the control lever being manually operated in a manual transmission mode, a gear change is performed. An operation reaction force when the control lever is manually operated is set larger when the gear change is performed in the manual transmission mode than when the range position is switched in the range switchable mode.

  • Patent number: 11240912
    Abstract: A cavity elongated in one direction is formed in a protective film covering the conductive pattern of the topmost conductive layer of a multilayer wiring substrate. The cavity exposes part of the conductive pattern. A first via-conductor extends downward from the conductive pattern of the topmost conductive layer at least until that of a second conductive layer. Second via-conductors extend downward from the conductive pattern of the second or third conductive layer at least until that of a conductive layer one below. As viewed from above, the first via-conductor and the cavity partially overlap each other. At least two second via-conductors are disposed to sandwich the cavity therebetween. The difference between the smallest gap between the cavity and the second via-conductor at one side and that between the cavity and the second via-conductor at the other side is smaller than the smallest gap between the cavity and the second via-conductors.

  • Publication number: 20210404552
    Abstract: A transmission system configured to perform a gear change based on a shift operation by an operator is provided, which includes a power transmission system including a transmission and configured to transmit an engine driving force to wheels, a shift operation detecting module, and a transmission controlling module adapted to be executable of a manual rotation synchronizing mode having first and second steps. In the first step, when a first shift operation for changing the transmission to a lower-speed side is detected, the transmission controlling module sends a control signal to a connecting-and-disconnecting mechanism provided to the power transmission system to suspend the transmission of the driving force. In the second step, when a second shift operation is detected, the transmission controlling module sends a control signal to the connecting-and-disconnecting mechanism to resume the transmission of the driving force while the transmission is switched to the lower-speed side.

  • Publication number: 20210137078
    Abstract: Provided are a livestock sensor device, a livestock astasia inference method, a livestock astasia inference program, and a livestock management system that are capable of preventing damage to stockbreeders. According to an embodiment of the present technology, there is provided a livestock sensor device including a postural-state determination unit, a state inference unit, a transmission unit, and a casing. The postural-state determination unit determines in which of a prostrate state and a non-prostrate state a livestock animal has been on a basis of output values from an acceleration sensor. The state inference unit infers whether or not the livestock animal has developed astasia on a basis of a duration of the prostrate state. The transmission unit transmits, to a server, an astasia-notification data item indicating that an inference that the livestock animal has developed the astasia is made when the inference that the livestock animal has developed the astasia is made.
