  • Patent number: 12095050
    Abstract: A secondary battery protection apparatus includes a temperature sensitive element and a secondary battery protection circuit with a first terminal coupled to an external device and the temperature sensitive element to control charge and discharge using a switching circuit to protect a secondary battery from temperature, and a conversion circuit of the secondary battery protection circuit is controlled such that a first input of a comparison circuit to compare a voltage against a threshold is electrically coupled to the first terminal of the secondary battery protection circuit, the voltage corresponding to a change in temperature of the secondary battery.

  • Patent number: 11969662
    Abstract: There is provided a robot device including: a head portion coupled to a trunk; four leg portions on a front left, a front right, a rear left, and a rear right coupled to the trunk; a first indirect portion that tilts the head portion left and right; and a second joint portion that rotates, with respect to the trunk, one of the leg portions on the rear left and the rear right to a front side, and the other to a rear side. It is possible to faithfully reproduce the movement of the four-legged animal by providing the first joint portion and the second joint portion.

  • Patent number: 11575161
    Abstract: A secondary battery protection circuit for controlling charge and discharge using a switching circuit to protect a secondary battery from temperature is provided. The switching circuit is configured to be provided in a charge-and-discharge path between the secondary battery and an external device. The secondary battery protection circuit includes a detection terminal configured to be electrically connected, via a resistor, to between the switching circuit and the external device. The secondary battery protection circuit includes a first terminal configured to be electrically connected to a temperature detection terminal of the external device. The secondary battery protection circuit includes a second terminal to which a temperature sensitive element is configured to be electrically connected, the temperature sensitive element having a characteristic value varying in accordance with a change in temperature of the secondary battery.

  • Patent number: 11465193
    Abstract: There is provided a conveying device that reliably discharges only scrap when simultaneously conveying the scrap and a pressed product without sacrificing cycle time. A conveying device for use in press forming includes: a conveying part that holds a product part and a scrap part of a workpiece after a cutting process, and conveys the product part and the scrap part to a next process; a nozzle part that is provided in the conveying part, and discharges compressed fluid toward the scrap part; and a controller that performs a control to release holding of the scrap part during conveyance of the workpiece and to blow compressed fluid toward the scrap part.

  • Patent number: 4440128
    Abstract: The idle air flow is adjusted by a step motor depending upon a drive signal applied to the step motor, so as to control the idling rotational speed of the engine. When the engine is under a certain operating condition during cranking, in which condition the step motor cannot be normally actuated, the drive signal is inhibited from being applied to the step motor.
