  • Publication number: 20220166227
    Abstract: There is fear that some battery cells among battery cells which are serially connected may consume electric power all the time, thereby causing expansion of unbalance in voltage of the battery cells and hindering electric discharge of a battery system. When a second battery has a sufficient voltage, an electric current control board supplies operating power to a battery control unit and a relay via an external minus line and an external plus line. On the other hand, when the voltage of the second battery has decreased, the electric current control board supplies the operating power from a first battery to the battery control unit and the relay via an internal minus line and an internal plus line. A first electric current control unit and a second electric current control unit control the supply of the operating power according to, for example, the decrease in voltage of the second battery.

  • Patent number: 11180260
    Abstract: A conventional parachute requires a velocity pressure during descent in order to open the parachute. As a result, a minimum descent distance and time are required from the beginning to the end of the parachute opening operation and use at low altitude has to be restricted. In order to remedy this issue, an airtight tube and a compressed gas device are provided together in a section of the parachute having the largest annular shape when the parachute has been opened. The tube is annularly expanded by the pressure of the gas, and the parachute is forcibly deployed and opened.

  • Patent number: 10975091
    Abstract: The problem to be solved by the present invention is to provide a compound suitable for a pharmaceutical composition, specifically a pharmaceutically composition for treating nocturia. The inventors have assumed that inhibition of nocturnal activity of placental leucine aminopeptidase (P-LAP), i.e. aminopeptidase that cleaves AVP, would maintain and/or increase an endogenous AVP level to enhance the antidiuretic effect, which would contribute to a decreased number of nocturnal voids, and have extensively studied compounds which inhibit P-LAP. As a result, the inventors have found that (2R)-3-amino-2-{[4-(substituted pyridine)-2-yl]methyl}-2-hydroxy-propanoic acid derivatives have excellent P-LAP inhibitory activity. The inventors have evaluated antidiuretic effects in water-loaded rats and have found that the compounds increase endogenous AVP levels by inhibiting P-LAP and consequently reduce urine production.
