  • Patent number: 12099323
    Abstract: A power supply apparatus generates an output voltage. A boost circuit boosts a voltage supplied from a reference voltage source and generates a first power supply voltage. A processor controls switching the boost circuit on and off. A first transistor is connected to the first power supply voltage. A second transistor is connected to a collector of the first transistor. A resistance element is connected to a collector of the second transistor. A voltage source is connected to the resistance element and generates a second power supply voltage. A collector voltage, which is an output voltage, of the second transistor is controlled by controlling an amount of base current of the first transistor.

  • Publication number: 20240308326
    Abstract: A ball bearing on one rotary shaft, out of a first rotary shaft and a second rotary shaft, on which a rotation member corresponding to a larger value of a ratio out of values of ratios of a rotation speed of a first rotation member and a rotation speed of a second rotation member relative to a rotation speed of a third rotation member is arranged does not include an inner race. Thereby, a ball PCD can be reduced while securing durability of a ball bearing on the one rotary shaft, and dragging loss between balls of the ball bearing and the inner race can be reduced. Since the ball bearing integrally configured with the rotary shaft is arranged on the one rotary shaft, reducing dragging loss of the ball bearing relatively largely reduces motive power loss on the third rotary shaft due to dragging loss of the ball bearing.
