  • Publication number: 20230077553
    Abstract: The present invention is a method for manufacturing a secondary battery. An electrode assembly and an electrolyte are accommodated into a body of a battery case. The body of the battery case has an accommodation part and a gas pocket part, and a passage that extends from the accommodation part to the outside discharges an internal gas from the accommodation part through the gas pocket part. The battery case is seated in a seating step on a support block, which has an inclined part on a side surface thereof, to support the battery case. The body is pressed to discharge a gas accommodated in the accommodation part through the gas pocket part in the battery case. This method allows easy discharging of internal gas while reducing discharge of the electrolyte with the gas.

  • Publication number: 20220273880
    Abstract: A needleless syringe having a multi-nozzle and a manufacturing method therefor are proposed. The needleless syringe injects a drug solution through an injection nozzle by expanding a pressure-generating liquid by means of energy generated from a pressure-generating unit, wherein precise branch channels are stably formed so as to inject drugs into a plurality of parts by using multiple injection nozzles. Further, the present disclosure has advantages in that: one energy-generating unit is used and thus nozzles can be densely arranged with a small distance therebetween; when several injections into an affected part are needed, the treatment time can be shortened using multiple injection nozzles; and an inner chamber is inserted into and coupled to or is insert injection-molded in an outer chamber so that more stable and precise branch channels can be formed, and thus multiple drugs can be stably injected into an affected part through multiple injection nozzles.

  • Patent number: 11398584
    Abstract: Disclosed is an ultraviolet light-emitting element which uses an electron emission operation. The ultraviolet light-emitting element is sealed to maintain a high degree of vacuum. A emission substrate is prepared for the electron emission and an electron emitted from the emission substrate passes through a control substrate. The electron, which has passed through the control substrate, collides with a light-emitting substrate, from which formation of a p-type semiconductor has been excluded, and thus forms ultraviolet light.

  • Patent number: 9829392
    Abstract: The present disclosure relates to an apparatus and method for estimating a temperature of a motor using a Hall sensor. The method includes detecting, at a digital Hall sensor, a position of a rotor included in a motor and outputting an on signal in an operating period and an off signal in a release period according to a relative position of the rotor, calculating, at a temperature determining module, a difference between duration of the operating period and duration of the release period according to an output waveform of the digital Hall sensor, and then determining, at the temperature determining module, a temperature of the motor with reference to a temperature corresponding to the duration difference. Accordingly, it is possible to estimate the internal temperature of a motor without installing a temperature sensor in the motor, to maintain a small size of the motor, and to reduce production costs.
