Abstract: The present invention provides a novel use of a Maydis stigma extract in prophylaxis, alleviation, or therapy of sleep disorder. A Maydis stigma extract has the effect of reducing sleep onset latency and increasing sleep duration, as high as or higher than the effect of ketamine or pentobarbital, which are conventionally used as soporifics. As a natural substance, the Maydis stigma extract does not cause side effects, such as cytotoxicity, resistance, or dependency, even when used for a long term.

Abstract: The present invention relates to a multifunctional locking device for a container of a trailer, in which a lock is operated by the weight of the container, whereby it is possible to automatically or manually lock the container to the trailer, and it is possible to prevent movement and disengagement of the container due to the increased fixing force of the container during trailer operation, thereby improving stability.

Abstract: The present invention provides a locking apparatus of a container for a trailer that can fixing a container by automatically or manually coupling the container to a trailer, using a locking pin that is operated by the weight of a container, and can improve stability by preventing movement and separation of a container from a trailer in transportation. The locking apparatus includes: an outer housing; an inner housing; an automatic actuator; a locking pin having a cylindrical body, a head, a first locking protrusion, and a guiding portion; a guide member; and a manual actuator having an extension, a length adjusting portion, and a lever.

Abstract: A solderable electric connector formed of a metal sheet as a single body includes a flat bottom portion soldered to a conductive pattern of a printed circuit board (PCB), an elastic fastening portion bent and extended from one end of the bottom portion in a longitudinal direction thereof, and a housing vertically bent and extended from one end of the bottom portion in a width direction and surrounding the elastic fastening portion. Herein, a front end of the housing is vertically bent downwards and forms a supporting plate and a penetration hole is formed in a certain location on the supporting plate. Also, a pressurizing projection projects from a top surface of the elastic fastening portion and a metal core of a wire passing through the penetration hole is pressurized between the pressurizing projection and a bottom surface of the housing and coupled therewith.

Abstract: Disclosed is a junction box which includes voltage and current sensors that are connected to both ends of bypass diodes provided within the junction box to sense currents and voltages of the solar cell module; a MPPT controller that tracks a maximum power point from current and voltage values sensed from the voltage and current sensors; and a voltage controller that includes a switch for controlling an operation of the solar cell module, and controls a voltage corresponding to the tracked maximum power point to be output.

Abstract: The present invention relates to a smart junction box for a solar cell module, and provides a smart junction box for a solar cell module which enables an operator to easily connect and separate ribbon cables using the operation of the levers of pressing units, thereby being able to improve the contact stability of ribbon cables, and which has a heat sink structure, thereby effectively emitting the heat generated by the ribbon cables and the diodes to the outside. For this purpose, the smart junction box for a solar cell module of the present invention includes bus bars for transmitting electricity flowing from ribbon cables; and pressing units for selectively fastening and separating the ribbon cables located on contact portions of the bus bars depending on whether both ends of the lever projected by the manipulation of an operator are inserted into recesses formed in a body.

Abstract: Disclosed is a light diffusion plate for use in a backlight unit of a liquid crystal display or an illumination apparatus, which includes polycarbonate resin or polystyrene resin as a base resin, so that appropriate brightness and high hiding properties or appropriate hiding properties and high brightness are exhibited, and thus, while minimizing the use of additional optical films, brightness is sufficiently high, therefore maintaining good light emission quality. The diffusion plate has high ability to hide a light source, is inexpensively manufactured, and has high dimensional stability, so that no curling occurs even under high-temperature and high-humidity conditions, leading to excellent light properties.

Abstract: A test method for testing a semiconductor device includes providing a tester which generates a plurality of general clock signals and which has a minimum test cycle time greater than an operational cycle time of the semiconductor device. Then a modulated clock signal is generated from a first general clock signal and a second general clock signal so that the modulated clock signal has a minimum cycle time no greater than the operational cycle time. The next steps include supplying the modulated clock signal to the semiconductor device as a predetermined control signal, supplying test signals to the semiconductor device as specified by a functional test item, and comparing an output of the semiconductor device to a reference value.
