  • Publication number: 20210091725
    Abstract: In a limiting circuit that limits an output voltage of an operational amplifier, the signal quality of the output voltage is improved. The limiting circuit includes a short-circuit transistor and a gate voltage supply unit. In the limiting circuit, the short-circuit transistor short-circuits a path between an input terminal and an output terminal of the operational amplifier in a case where a voltage between the input terminal of the operational amplifier and the gate is higher than a predetermined threshold voltage. Furthermore, in the limiting circuit, the gate voltage supply unit supplies a voltage to the gate, the voltage depending on the threshold voltage and the output voltage of the output terminal.

  • Publication number: 20200358148
    Abstract: The present invention states a method of producing new cathode materials for lithium ion batteries by recycling metals from depleted lithium-ion batteries using green reagents, and a method of deriving green reagents from agricultural products. The green reagents are used to replace corrosive acids that are used in the recycling process of depleted lithium-ion batteries. Metal ions, such as nickel, cobalt, manganese, and lithium are recovered as precipitates from the depleted lithium-ion batteries which can further be sintered to produce lithium-containing transition metal oxides that can be used as new cathode material for lithium-ion batteries.

  • Publication number: 20200326891
    Abstract: In a method for accessing a storage system, a client in the storage system identifies a logical address of a storage device, and queries a management server regarding a mapping between the storage device and a start address of a submission queue (SQ) in the memory of the storage node. The client then sends an access request including the logical address of the storage device directed to the start address of the SQ to a network interface card NIC of the storage node. The NIC receives and sends the access request to the start address of the SQ in the memory. The storage device obtains the access request from the start address of the SQ and executes the access request.

  • Patent number: 10086645
    Abstract: Disclosed is a hydraulic bushing and a rail vehicle. The hydraulic bushing comprises: a core shaft; a sleeve mounted on the core shaft, wherein a first rubber body is filled in a space formed between the core shaft and the sleeve, and a groove is provided on an outer surface of the sleeve; and an outer housing, which is mounted on the sleeve through press fit. Two liquid chambers for accommodating liquids are provided diametrically opposite to each other on the first rubber body, and the groove and the outer housing together define a flow channel, through which the two liquid chambers communicate with each other. Use of the hydraulic bushing on the rail vehicle not only can assure stable operation of the vehicle in a straight running state thereof, but also can reduce abrasion of a wheel and a rail in a curve running state.

  • Publication number: 20170039359
    Abstract: An electronic device controlling method and a user registration method are provided. In the electronic device controlling method, when a target device receives a first and a second control commands which are identical, but performed by different users simultaneously or separately, the target device performs a first predetermined operation based on an identity of the user performing the first control command, and performs a second predetermined operation based on an identity of the user performing the second control command. In the user registration method, a user registered identity model corresponding to a user to be registered is established according to identity information of the user, and is mapped to a user profile comprising a relationship between the control commands and the predetermined operations. By acquiring the registered information, the target device is able to perform the user dependent operations.
