Abstract: An integrated certification system is a system for performing integrated certification on products to which genuine-product certification labels are attached. The integrated certification system includes an integrated certification management server. The integrated certification management server includes a distribution management module configured to acquire distributor identification information and a distribution number of each of the products from each distributor and match the distribution number to an identification number assigned to a corresponding distributor and a genuine-product certification module configured to receive a genuine-product certification request including user-related information and an identification number extracted from each of the genuine-product certification labels from a user terminal and perform genuine-product certification according to the received genuine-product certification request.

Abstract: An embodiment rehabilitation robot control apparatus includes a brainwave signal measuring device configured to measure a brainwave signal of a user, a preprocessing device configured to preprocess the measured brainwave signal, a classification device configured to classify a motor intention of the user based on the brainwave signal preprocessed by the preprocessing device, and a controller configured to reflect the motor intention of the user in real time to control an operation or a stop of a rehabilitation robot.

Abstract: A tripod constant velocity joint includes: a spider having a plurality of trunnions; a plurality of roller assemblies which are respectively assembled to the plurality of the trunnions; and a housing defining a plurality of track grooves which respectively receive the plurality of roller assemblies. The respective roller assembly includes: an inner roller which is coupled to the trunnion; an outer roller which is disposed to surround the inner roller; a needle roller which is interposed between the inner roller and the outer roller; and an elastic member which elastically supports the outer roller outwardly in a radial direction with respect to the inner roller.

Abstract: A constant-velocity universal joint includes: an outer joint member having a plurality of outer ball grooves; an inner joint member having a plurality of inner ball grooves; a plurality of torque transmitting balls; and a ball cage. The outer ball groove and the inner ball groove respectively have a double shape, and a ratio O/H of an offset value O which is a distance between an inflection point of the outer ball groove and a line connecting centers of the torque transmitting balls in a state that the outer joint member and the inner joint member form 0 angle and a distance H between a center line of the inner joint member and a center of the torque transmitting ball in a state that the outer joint member and the inner joint member form 0 angle is within a range of 0.07 to 0.11.

Abstract: Provided are a hollow drive shaft and a method for manufacturing the same in which a concentrated load to a weak point which may be occurred by differences of sectional thicknesses and outer diameters of the shaft is dispersed so that the strength may be uniform throughout the whole length of the drive shaft. The hollow drive shaft includes: one or more small-diameter portion having a hollow shape; and a large-diameter portion which is disposed in a vicinity of the small-diameter portion and has an outer diameter relatively greater than the small-diameter portion. A sectional thickness of the large-diameter portion is less than a sectional thickness of the small-diameter portion, and a first sectional portion from an outer surface to a point corresponding to 35% to 60% of a sectional thickness of the large-diameter portion is carburized to have a first hardness.

Abstract: A mouthpiece for an endoscope includes a main body disposed to closely contact an outer side of a mouth and provided with an central insertion hole through which the endoscope is inserted, an guide body supported on the central insertion hole of the main body to guide insertion of the endoscope, and a movement preventing unit disposed in an oral cavity to prevent the mouthpiece from moving in the oral cavity. The guide body and the movement preventing unit may designed to be separable from the main body.

Abstract: A method for treating the surface of a silicon substrate, which has been subjected to a dry etching process, including applying an electron cyclotron resonance process to the exposed surface to thereby etch away a thin layer of the exposed surface. The ECR etching process is preferably conducted in an SF.sub.6 --O.sub.2 gas mixture and the thickness of the thin layer is no greater than 500 .ANG.. The silicon wafer damaged and contaminated by the dry etching processes can be repaired to the level of virgin, bare silicon wafer by this method. This silicon wafer treatment method allows the semiconductor device thereby fabricated to have improved operating characteristics. For example, the leak current generated in a semiconductor device fabricated on the silicon wafer which has undergone the present treatment is markedly diminished to approximately one-tenth of the leak current generated in the semiconductor device fabricated on the silicon wafer which has not undergone this treatment.
