Abstract: Disclosed herein is a light concentrating device which is arranged in a space defined by three axes orthogonal to each other and has a first specular surface and a second specular surface. The first specular surface concentrates incident lights in any one two-dimensional direction and reflects the incident lights as first reflected lights, and the second specular surface concentrates the first reflected lights in the other two-dimensional direction and reflects the first reflected lights as second reflected lights to reach a target area. Accordingly, the first specular surface and the second specular surface are easy to manufacture. The first specular surface, the second specular surface, and the target area are arranged not to block the first reflected lights and the second reflected lights, so there is no light loss. The first specular surface, the second specular surface, and the target area occupy small areas with respect to a plane perpendicular to the incident lights.

The module for cooling the heating element, according to the present invention, can comprise: a flat plate-shaped heat pipe containing working fluid therein, coming into close contact with the heating element, and including a condensation region which does not come into contact with the heating element; and a cooling channel connected to the condensation region, and cooling the heat pipe by a refrigerant.

Abstract: A lithium secondary battery is provided. Electrolytes of the lithium secondary battery are divided between an anode and a cathode into a plurality of regions not to contact with each other, thereby limiting movement paths of lithium ions. In this way, the lithium secondary battery inhibits growth of dendrite and improves energy density. Also, the lithium secondary battery that has a partition wall structure reduces leakage even when liquid electrolytes are used and actively copes with pressure applied to the battery.

Abstract: A multi-reflecting device includes a plurality of double reflecting surfaces formed serially on the rear of a light guide plate having a taper shape. A light incident upon the light guide plate is double-reflected, and progress in a desired direction. The multi-reflecting structure is applied to a backlight unit and a display device so that the backlight unit and the display device can be slimmer economically.

Abstract: Disclosed is a squeeze for a screen printer. The present invention provides a squeeze for a screen printer, which coats a printed circuit board with an adhesive paste while moving parallel over a metal mask on the printed circuit board, the printed circuit board being open through an opening of the metal mask, the squeeze including a solvent storage unit for storing solvents; and solvent discharging holes for discharging the solvents, stored in the solvent storage unit, to an adhesive paste. Accordingly, the squeeze for a screen printer of the present invention may be useful to prevent a dog ear phenomenon, namely that an adhesive paste layer is asymmetrically formed in an indented manner, by controlling a viscosity of an adhesive paste by discharging a solvent onto an adhesive paste layer that comes in contact with the squeeze when the adhesive paste layer is formed in the printed circuit board.

Abstract: A piston head of a hydraulic injection molding machine is screwed with a tie rod inside a hydraulic cylinder of the hydraulic injection molding machine. The piston head has a second screw formed in an inner circumference of a hollow of the piston head and engaged with a first screw formed in an outer circumference of the tie rod. An insert groove having a predetermined shape is formed in the inner circumference of the piston head in front of the second screw.

Abstract: A mold adjustment device of an injection molding machine is required for movement of a rear template that moves depending on a size of a mold in a toggle clamp of the injection molding machine. At this time, a spherical bearing and/or a bushing is attached to an outer circumference of a nut of a tie bar gear that rotates along a tie bar and a tie bar screw enduring a clamping force of the toggle clamp so as to be contacted with the rear template. This mold adjustment device clears up any factor generating vibration or noise during the injection molding, thereby remarkably decreasing stoppage generated during the mold adjustment process and also relatively reducing vibration and noise.

Abstract: When an optical fiber preform is manufactured using MCVD (Modified Chemical Vapor Deposition), dehydration gas supplied into a tube on which soot particles are deposited is preheated at 600 to 1200° C. so that an internal temperature of the tube is kept over 500° C. in order to improve efficiency of the dehydration process for removing hydroxyl groups. At this time, a preheater for preheating is installed near a front end of the tube where the dehydration gas is introduced, or installed at a predetermined position of a gas supply line, or installed on a gas path in a main pillow. In addition, the preheater is capable of controlling thermal capacity, and a heatproof plate is installed around the preheater.
