Abstract: A vehicle control device includes a processor and memory. The memory stores relation-defining data for defining a relation between a state of a vehicle and an action variable that is a variable relating to operations of a transmission installed in the vehicle. The processor is configured to execute acquisition processing, operation processing, reward calculation processing, updating processing, counting processing, and limiting processing. The processor is configured to output the relation-defining data updated so that an expected income is increased when the transmission is operated following the relation-defining data, based on an updating map.

Abstract: There is provided a syringe capable of preventing the occurrence of “link-thread” from the distal end nozzle when the cap is pulled out, even in the case where the medicinal liquid filled has a high viscosity. The inner peripheral surface (631) of the seal cap (63) in the cap (6) is brought into close contact with the outer peripheral surface (214) of the distal end side portion of the distal end nozzle (21) in the barrel (2) so that the distal end opening (211) is hermetically closed off. At the same time, the outer peripheral side of the luer lock adapter (22) is covered with the outer tubular cover (62) of the cap. The bulge part (213) is formed in the distal end side portion of the inner aperture (212) in the distal end nozzle so that the aperture diameter (d) of the distal end opening is reduced to a small aperture diameter and, in addition, the length of seal (s) by the seal cap (63) is made to be a relatively short, predetermined length.

Abstract: There is provided a injector in which a backstop function is realized by a collar part at a position situated away from a gasket in the direction of the side of the proximal end and adequate sterilization can be carried out, with a plunger rod (in which the collar part is formed) assembled, while aiming to secure airtightness. (A backstop function is realized by means of a collar part at a position situated away from the gasket in the direction of the side of the proximal end, thereby providing a injector capable of being adequately sterilized with a plunger rod (in which the collar part is formed) assembled, while aiming to secure airtightness.) A gasket (3) is inserted from a proximal end opening (22) of a barrel (2). Next, a plunger rod (4) is inserted as to establish connection of its distal end and the gasket (3). Then, a finger grip (5) is mounted to a flange (23).
