Abstract:
A light emitting device includes a substrate and a plurality of protrusions protruding from a top surface of the substrate. A first semiconductor layer is provided on top surfaces of the protrusions and a plurality of seed patterns protrudes from a bottom surface of the first semiconductor layer toward the protrusions. A medium layer is provided between the protrusions and a light emitting structure on a top surface of the first semiconductor layer. The bottom surface of the first semiconductor layer is located at a higher position than that of each of the protrusions, and the first semiconductor layer contacts a c-plane of each protrusion.
Abstract:
Disclosed herein are a stature measuring method and a stature measuring device using the method. The method includes securing an anchoring unit, coupled to a main body via a tape, to a building wall, moving the main body to a bottom in a state in which the anchoring unit is secured to the building wall, inputting a reference point setting signal in a state in which the main body comes into contact with the bottom, and moving the main body from the bottom to a position above an examinee's head, and measuring a distance from a point where the reference point setting signal is input to a point where the main body is moved above the examinee's head, thus determining the examinee's stature.
Abstract:
Provided are a light emitting device and a light emitting device package. The light emitting device comprises a light emitting structure comprising a first conductive type semiconductor layer, an active layer on the first conductive type semiconductor layer, and a second conductive type semiconductor layer on the active layer; a first electrode on the first conductive type semiconductor layer, the first electrode being electrically connected to the first conductive type semiconductor layer; a plurality of reflective islands on the second conductive type semiconductor layer; a second electrode on the second conductive type semiconductor layer and the plurality of reflective islands, the second electrode being electrically connected to the second conductive type semiconductor layer; and a conductive support member on the second electrode.
Abstract:
Disclosed herein is a tape measure with a self-regulating speed control mechanism. In the present invention, when a bobbin rotates, a rubber roller rotatably provided on a movable mounting plate alternately comes into contact with an inner surface of a support ring and a rubber acceleration prevention member provided on the inner surface of the support ring, so that the speed of the bobbin can be smoothly and reliably reduced.

Abstract:
Disclosed herein is a tape measure with a self-regulating speed control mechanism. The tape measure is capable of self-regulating its speed so that the retraction speed of a blade is not too fast or slow, and does not introduce any noise to the working environment in the case where the speed of the blade is not reduced. According to the present invention, a rotary brake part is elastically biased by a second elastic member, and is brought into contact with a stationary brake part only when the rotating speed of a bobbin is very fast.
Abstract:
A tape measure includes an automatic blade extension mechanism. The tape measure allows a user to draw and lock a blade using only one hand, when measuring a dimension of an object, thus allowing the other hand to be freely used in a workplace where several operations must be carried out. Therefore, the tape measure allows the user to simultaneously perform a cutting operation, a hammering operation, a marking operation, etc. during the measuring operation. Thereby, the tape measure of this invention is convenient to use, and increases work efficiency.
Abstract:
The present invention relates to a flat wiper blade for a vehicle, and more particularly, to a flat wiper blade for a vehicle, which is constructed to allow a blade and spoilers to be integrally assembled with each other via an auxiliary coupler so that the blade and spoilers, fitted into and coupled to the auxiliary coupler, can be easily decoupled from the auxiliary coupler and replaced with new ones or different ones. According to the present invention, spoilers and a blade, which are fitted and coupled into an auxiliary coupler, can be easily replaced through simple manipulation. Spoilers having a variety of colors or patterns can be easily installed, so that a wiper blade for a vehicle can be decorated in various ways in conformity with the taste and character of a user. Also, since manufacturing and assembling processes can be simplified, manufacturing costs can be significantly reduced.
Abstract:
A combination of a transparent resin and a paper cover sheet and a coupling method thereof. The combination comprises a piece of transparent resin having a receiving space, which is defined in the center portion thereof, and marginal portions, which are formed in the periphery of the center portion and are folded inward such that upper and lower bonding parts are formed; and a paper cover sheet inserted between the upper and lower bonding parts of the marginal portions of the piece of transparent resin and having one or more through-holes which are defined through peripheral portions thereof, wherein, after the paper cover sheet is inserted into the piece of transparent resin, the upper and lower bonding parts of the piece of transparent resin are bonded with each other through the through-holes in the paper cover sheet.
