Abstract:
The present invention relates to a catalyst having surface-modified metal nanoparticles immobilized in a stationary phase in which a polymer electrolyte membrane is formed, and a preparation method thereof. The catalyst of the present invention may be used in a process for producing hydrogen peroxide by direct synthesis from oxygen and hydrogen.
Abstract:
A one hand lipstick container includes: a container main body having a cylinder standing at the center of a body and a center through-hole; a container cover rotatably connected to the upper portion of the container main body and having an open inlet; a cover holder combined by a spiral with the outer side of the cylinder of the container main body and vertically moving up/down by rotational force of the container cover; a door hinged to the cover holder to open/close the upper portion of the cover holder; a lipstick housing combined by a spiral with the inner side of the center through-hole of the container main body and vertically moved up/down by rotational force of the cover holder; and a vertical guide transmitting the rotational force of the cover holder to the lipstick housing and vertically guiding the lipstick housing to move up/down.
Abstract:
A dual type cosmetics case includes a plurality of liquid containing parts and inlets partitioned from each other by a vertical partition wall. A plurality of stems immersed into the respective liquid containing parts are mounted in such a way as to be detachably coupled to the liquid containing parts. Each stem is selectively coupled to a cap and then used. The dual type cosmetics case is advantageous in that different kinds or colors of cosmetic liquids are held in one case, so that a user need not carry or keep several different cosmetics, and thus, especially while traveling, the volume of items which are to be carried by a person can be reduced. Further, costs for purchasing cosmetics can be reduced, so that the cosmetics case is very economical.

Abstract:
Disclosed herein is a catalyst, including, in one example: a carrier, a polymer electrolyte multilayer film formed on the carrier, and metal particles dispersed in the polymer electrolyte multilayer film. The catalyst can be easily prepared, and can be used to produce hydrogen peroxide in high yield in the presence of a reaction solvent including no acid promoter.
Abstract:
A device (110) and method (700) for providing windows in a multi-environment operating system is provided. A first operating system environment (first OSE) (222) is executed in a native mode on a mobile device (110). The mobile device comprises a first graphical user interface (GUI) 112. The first OSE generates graphical data for a first OSE window (118). The first OSE window can be used on the first GUI for interfacing with the first OSE. A second operating system environment (second OSE) (224) is executed in a native mode on the mobile device, wherein the second OSE generates a GUI desktop (318) that is displayed on a second GUI (312). A second window (320) is rendered on the GUI desktop that comprises the first OSE window. The second OSE communicates relevant events to the first OSE, which are used by the first OSE to update the information used to render the first OSE window within the second OSE window.
Abstract:
The present invention relates to a patch for treating constipation, which contains rhubarb ingredients selected from among crude drugs (medical herbs). More particularly, the present invention relates to a patch for treating constipation in which powder obtained by boiling, filtering, and free-drying rhubarb selected from among pure crude drugs is applied to the patch, and the patch is attached to the recesses (arched parts) below the wrists of both hands of a patient, to thereby increase the metabolism of internal organs of the patient and exhibit the effects of treating or preventing constipation. The patch of the present invention can be simply attached to the skin of the patient instead of directly administering agents for treating constipation to the patient.
Abstract:
Provided is a modulation-index adjustable amplitude shift keying (ASK) transmitter including: a bias current supply unit supplying one or more bias currents in response to a digital signal that is to be transmitted and one or more bias current control signals; and a modulation signal generator generating a modulation signal corresponding to the digital signal by modulating a carrier signal in response to the one or more bias currents.
Abstract:
The present invention relates to a one-hand lipstick container, which includes: a container main body having a cylinder stood at the center of a body and a center through-hole formed through the center of the cylinder; a container cover that is rotatably connected to the upper portion of the container main body and has an open inlet formed through the upper surface; a cover holder that is combined by a spiral with the outer side of the cylinder of the container main body in the container cover and vertically ascends/descends by rotational force of the container cover; a door that is hinged to the cover holder to open/close the upper portion of the cover holder, opens a passage when the cover holder descends, and closes the passage when the cover holder ascends; a lipstick housing that is combined by a spiral with the inner side of the center through-hole of the container main body in the cover holder, vertically ascends/descends by rotational force of the cover holder, and ascends/descends in the opposite directions to the ascent/descent directions of the cover holder; and an anti-rotation means that transmits the rotational force of the cover holder to the lipstick housing and vertically guides the lipstick housing to ascend/descend in the opposite directions to the ascent/descent directions of the cover holder.
Abstract:
A method of manufacturing a cutting tool is disclosed. An object of the manufacturing method of a cutting tool is to reduce contamination of an abrasive layer surface, particularly, agglomeration contamination due to slurry by improving hydrophobicity maintaining performance of an abrasive layer. A cutting tool according to the method of manufacturing comprises an abrasive layer on a base member, the abrasive layer having abrasives bonded to a surface thereof; and a coating on the surface of the abrasive layer that is a hydrophobic material film.
