  • Patent number: 11614713
    Abstract: Provided is a timepiece including: hands being an hour hand, a minute hand and a second hand; a movement for driving the hands; a first dial; a first dial ring having upper and lower surfaces provided with an upper projection and a lower projection, respectively, the first dial ring being disposed on the first dial and positioned relative to the first dial by the lower projection; and a transparent second dial disposed on the first dial ring and positioned relative to the first dial ring by the upper projection, wherein one of the hands is disposed between the first dial and the second dial, while the others of the hands are disposed above the second dial.
    Type: Grant

  • Patent number: 11452256
    Abstract: An auto guide vehicle (20) that conveys a cart (10), wherein the auto guide vehicle (20) is provided with: a fluid pressure cylinder (22) that is able to be extended and retracted vertically, and that applies an upward pressing force to the floor surface of the cart (10); a fluid pressure supply device (70) that supplies a fluid to the fluid pressure cylinder (22); pressure regulating means (50) that regulates the fluid pressure of the fluid supplied from the fluid pressure supply device (70) to the fluid pressure cylinder (22); a control board (40) that outputs a fluid pressure command value to the pressure regulating means (50); and a pressure sensor (100) that detects the fluid pressure of the fluid supplied to the fluid pressure cylinder (22); wherein the control board (40) computes derivatives of the fluid pressure detected by the pressure sensor (100), estimates a timing at which the cart begins to leave the ground based on a pattern of the computed derivatives, and computes the command value by multipl
