Abstract: The present disclosure relates to a molded case circuit breaker. In accordance with one aspect of the present disclosure, a molded case circuit breaker for use in connection with a main busbar provided on a distribution board panel includes a power-source-side terminal provided to a front portion of a case and having a terminal assembly hole formed at an upper portion thereof; a base bus supporter comprising a connector protruding from a front surface thereof so as to engage with the main busbar installed on one side of the distribution board panel, the base bus supporter being coupled to an upper surface and a lower surface of the power-source-side terminal; an auxiliary cover plate coupled to an upper portion of the power-source-side terminal and provided with a temperature measurement hole communicating with the terminal assembly hole.

Abstract: A display panel includes a first substrate, a second substrate, a liquid crystal layer, a first polarizer, a second polarizer and a viewing angle control layer. The second substrate faces the first substrate. A liquid crystal layer is disposed between the first substrate and the second substrate. A first polarizer is disposed on a lower surface of the first substrate and includes a first polarizing layer and a second polarizing layer stacked on each other. A second polarizer is disposed on an upper surface of the second substrate. A viewing angle control layer is disposed on the first polarizer and is configured to control a viewing angle of a column direction of the display panel.

Abstract: Disclosed herein is a method of manufacturing a color-controlled sapphire, comprising: vaporizing a metal material, irradiating the vaporized metal material with electron beams or high-frequency waves to form the vaporized metal material into a plasma state, and then implanting the metal ions into a sapphire by extracting the metal ions from the plasma and accelerating the metal ions (step 1); and heat-treating the sapphire implanted with the metal plasma ions in an oxygen atmosphere or in air (step 2). According to the method of manufacturing a sapphire of the present invention, a sapphire, which can exhibit various colors, can be manufactured by implanting the ions, which can cause optical band gap changes into the sapphire, and a sapphire, which cannot be damaged by radiation and can exhibit colors uniformly, can be manufactured by conducting heat treatment under an oxygen atmosphere.

Abstract: A wireless network-based portable wireless flashing light system is based on a wireless network-based portable wireless flashing light. The wireless network-based portable wireless flashing light includes a wireless communication module, a display unit, an emergency alarm unit, and a control unit. The wireless communication module transmits and receives a wireless signal to and from an outside. The display unit displays predetermined information. The emergency alarm unit provides notification of an emergency. The control unit extracts status information about manufacturing machines from the signal received from the wireless communication module, displays information about a manufacturing machine in which an abnormality occurs on the display unit based on the status information, and operates the emergency alarm unit.

Abstract: An apparatus and a method of controlling a water supply of a washing machine, which naturally discharges the water within a detergent dissolving unit when the water level within the detergent dissolving unit is more than a designated water level so as to prevent the water within the detergent dissolving unit from overflowing, and warns of a clogging error in a water supply path when a number of times the water level within the detergent dissolving unit is more than a designated water level, is more than a designated number of times. Whether or not the water supply is provided is determined according to the number of times the water level within the detergent dissolving unit is more than the designated water level sensed by the water level sensor, thereby controlling a water supply action so as to stop the water supply only under abnormal conditions from supplying the water to a water tank, and improving a reliability of the apparatus.
