Abstract: Provided is a method for manufacturing a polarizing plate, comprising a step of irradiating an optical laminate with ultraviolet rays having an emission wavelength band of 380 nm to 410 nm. The optical laminate sequentially comprises a first base film, a first adhesive layer, a linear polarizer, a second adhesive layer, a second base film and a reverse dispersion liquid crystal layer. The first adhesive layer and the second adhesive layer each comprise a photosensitizer for initiating a curing reaction in a wavelength band of 350 nm to 410 nm, and the ultraviolet rays are irradiated on the first base film side of the optical laminate.

Abstract: A gripper includes a body part, a finger base part coupled to the body part to be rotatable, the finger base part including a first finger base part and a second finger base part configured such that when the first finger base part is rotated in a first direction with respect to the body part, the second finger base part is provided to be rotatable in a second direction opposite the first direction with respect to the body part, and a finger part coupled to a first side of the body part or the finger base part to be reciprocal.

Abstract: A gripper includes a body part, a finger base part coupled to the body part, and a finger part coupled to a first side of the body part or the finger base part and coupled to the body part or the finger base part to be reciprocal, wherein the finger part comprises a first link structure and a second link structure, sides of which are coupled to the finger base part, respectively, and wherein, in the first link structure and the second link structure, a first support area of the first link structure and a second support area of the second link structure reciprocate in only one of a plurality of directions that cross a direction in which the finger part reciprocates with respect to the finger base part.

Abstract: Provided are a filter unit which may easily replace a filter, and a refrigerator including the same. To this end, a filter unit according to the present disclosure includes a filter which purifies water, a filter head which is disposed on one end portion of the filter, and includes an inlet port which supplies raw water to the filter and is formed to protrude from one side thereof, and an outlet port which discharges pure water purified by the filter and is formed to protrude from the other side thereof, a filter housing which is formed with a filter accommodation space in which the filter is accommodated, a filter bracket which is coupled to the filter housing, and includes an inlet port coupling part to which the inlet port is coupled rotatably, and an outlet portion coupling part to which the outlet port is coupled rotatably, and a filter door which is coupled to the filter housing to open and close the filter accommodation space.

Abstract: An embodiment device includes an input module including a motor configured to generate a rotational force, an output module configured to receive power from the input module to be rotatable, and a connection module having a first side coupled to the input module and a second side, opposite the first side, coupled to the output module, wherein the connection module is configured to transmit the power from the input module to the output module.

Abstract: The present invention relates to an eddy current sensor for detecting a crack in a battery cell, and a system for detecting a crack of a battery cell including the eddy current sensor. According to the present invention, it is possible to easily detect a crack generated in an electrode, an electrode tab or a welded portion.

Abstract: A lens module includes a lens and a lens barrel accommodating the lens. A distance between an internal surface of the lens barrel and an optical axis varies in a circumferential direction of the lens barrel.
