Abstract: A sulfide-based solid electrolyte contains a nickel (Ni) element and a halogen element. For example, a sulfide-based solid electrolyte can include, with respect to 100 parts by mole of a mixture of lithium sulfide (Li2S) and diphosphorus pentasulfide (P2S5), 5 parts by mole to 20 parts by mole of nickel sulfide (Ni3S2), and 5 parts by mole to 40 parts by mole of lithium halide.

Abstract: A slot die coater is configured for making a coating width of a multi lane model uniform and reducing a condition adjustment loss in the subsequent production. The slot die coater includes an upper plate; a lower plate; and shims interposed between the upper plate and the lower plate and defining at least two individual lanes to form a slot. The shims defining the individual lanes include a fixing pin to improve positional precision when fixing to the upper plate or the lower plate and a fixing bolt for fixing to the upper plate or the lower plate.

Abstract: A method and apparatus for supplying insulating liquid to form an insulating coating layer on an electrode is disclosed herein. In some embodiments, an apparatus includes a storage tank for storing an insulating liquid; a coating die for coating the insulating liquid on an electrode; a supply line which supplies the insulating liquid from the storage tank to the coating die; a pump connected to the supply line; a defoaming tank connected to the storage tank and supplies defoamed insulating liquid to the storage tank; a vacuum pump which defoams bubbles of the insulating liquid by applying vacuum to the defoaming tank; a bubble sensor connected to the supply line, wherein the bubble sensor senses generation of bubbles in the supply line in real time; and a controller for adjusting an operating condition of the apparatus based on an amount of bubbles sensed by the bubble sensor.

Abstract: Disclosed herein is a roundness measuring device and a roundness measuring method of a coating roll for battery manufacturing. The roundness measuring device of a coating roll that supports an electrode sheet when the electrode sheet is coated with an electrode slurry, the roundness measuring device comprising: a displacement sensor spaced apart from the coating roll and configured to measure roundness of the coating roll in a non-contact manner; and a support member on which the displacement sensor is installed and which extends in a length direction of the coating roll, wherein the displacement sensor is installed as a plurality of displacement sensors on the support member in the length direction of the coating roll.

Abstract: Disclosed is a use of rice, rice bran or rice hull extract as a histamine receptor antagonist. The rice, rice bran or rice hull extract may be used as a natural antihistamine to prevent or treat allergic rhinitis, inflammatory bowel disease, asthma, bronchitis, nausea, gastric and duodenal ulcer, gastroesophageal reflux disease, sleep disorder, anxiety and depression. It provides comparable or better effect of decreasing sleep latency, increasing sleep duration and increasing non-REM sleep as compared to diazepam, which is currently used as sleeping drug. Derived from the natural product rice, rice bran or rice hull, it has no side effect such as cognitive impairment, resistance or dependency even after long-term use.

Abstract: Disclosed are a novel 8-hydroxyquinoline acetamide compound, an 8-hydroxyquinoline thioamide and use thereof. More specifically, disclosed are a novel 8-hydroxyquinoline thioamide compound suitable for use as a selective chemodosimeter that shows considerably high detection sensitivity to mercury ions, an 8-hydroxyquinoline acetamide compound as an intermediate thereof, preparation thereof, and a chemodosimeter for mercury ion-selective detection, the chemodosimeter comprising the 8-hydroxyquinoline thioamide compound. The compounds as disclosed herein exhibit considerably effective fluorescence specificity of an off-on type, detect a micromole of mercury ions from chemical and biological aqueous systems, and allow 100% desulfurization within 5 minutes, thus being considerably useful in the chemical industry.

Abstract: Disclosed herein is a stepping motor. The stepping motor include a bracket including a fixing hole; a shaft supporter rotatably supporting one end of a shaft and fitted into the fixing hole; and a pressure supporter pressing and supporting the fixing hole and the shaft supporter while forming a plurality of pressure support points between the fixing hole and the shaft supporter. As such, the plurality of pressure support points is formed between the shaft supporter and the fixing hole, thereby enabling the shaft supporter to be stably press-fitted into and fixed to the fixing hole of the bracket.

Abstract: Disclosed herein is a bracket for a stepping motor. The bracket includes a plate-shaped welding section, through which a shaft passes, and a welding zone formed on one side of the welding section and having a smaller thickness than the welding section. The bracket has improved welding strength with respect to a housing of the stepping motor.
