  • Patent number: 11124194
    Abstract: A wakefulness inducing system is capable of appropriately inducing a wakeful state in a driver even in a self-driving vehicle. A wakefulness inducing system includes a wakefulness degree sensing apparatus that senses the degree of wakefulness of a driver, a touch operation apparatus including a touch operation interface that detects contact by the operating hand of the driver, and a self-driving apparatus that controls self-driving of a vehicle. When the wakefulness degree sensing apparatus senses a reduction in the degree of wakefulness of the driver, the self-driving apparatus provides an instruction to the driver to move the operating hand to the touch operation interface, and the temperature of the operating hand is lowered in the touch operation interface upon detection of contact of the operating hand by the touch operation interface.

  • Patent number: 10639162
    Abstract: The present invention provides an artificial knee joint that can reconstruct an anterior cruciate ligament in a state close to an original function. An artificial knee joint (1) that is used in a total knee replacement includes a femur member (10) and a tibia member (20). The tibia member (20) has a ligament insertion hole (20h) which pierces the tibia member (20) and which is formed at a position where once an anterior cruciate ligament (ACL) exists in a knee replaced for the artificial knee joint (1). Therefore, a ligament can be provided such that a distal end (DT) of a femur (F) and a proximal end (PE) of a tibia (T) are joined to each other by passing the ligament through the ligament insertion hole (20h), which allows the anterior cruciate ligament (ACL) to be reconstructed so as to be in the substantially same state as a knee replaced for the artificial knee joint (1).

  • Patent number: 7766725
    Abstract: A loader arrangement 7 of a shot-blasting machine includes a bucket loader 29 having a tip opening that can be opened and closed by means of a lid 35. The loader arrangement 7 also includes a swivel arm 32, which is vertically and pivotally attached to a frame 4 via a linkage 31, for vertically swiveling the bucket loader 29, and a chain block 34 for swiveling the arm 32. Once the bucket loader 29 has reached the upper position above a rotary drum 5 by means of the swivel arm 32, a guide means 30, which is attached to the arm 32, allows the bucket loader 29 to approach the drum 5 through its top opening by driving a hydraulic cylinder 33, while the tip of the bucket loader 29 is opposed to the bottom wall of the drum 5. Once the tip of the bucket loader 29 is close to the bottom wall or the inner peripheral wall of the drum 5, the lid 35 is opened to drop the work pieces in the bucket loader 29 into the drum 5.

  • Patent number: 7042188
    Abstract: A servo motor with a built-in drive circuit is provided in which, when power is off, positional data including multiple-rotation counting values is stored in a nonvolatile memory to thereby eliminate battery back-up, and in which the CPU of a drive control circuit portion is in charge of the multiple-rotation counting itself to thereby eliminate the circuit for multiple-rotation counting. Due to a reduction in the number of lines involved and an elimination of battery back-up, a reduction in size is achieved. The servo motor with a built-in drive circuit includes an absolute encoder for detecting rotation of a servo motor portion and an electromagnetic mechanical brake, in which, when the power is off, the positional data at that time is stored in a nonvolatile memory.

  • Publication number: 20040239196
    Abstract: The present invention provides a motor with a brake in which, after an initial stage, a voltage applied to the brake is reduced to thereby restrain heat generation in the brake. In the motor with a brake, after signal drive, a voltage of a drive signal supplied to an electromagnetic drive portion of the brake is reduced, whereby heat generation in the brake during motor rotation is restrained, which makes it possible to increase a load to be applied to the motor.
